 Jambala-Intelligence beyond digital wireless

New,high-value services that target an increasingly segmented end-user market are instrumental in retaining and expanding an operator's subscriber base. Scalable and flexible application platforms are needed to provide the basis for network nodes that cater to such needs.

Jambala is a next-generation application platform that truly fulfills these requirements. In its initial installation, it accommodates HLR/AC and SCP applications and services for D-AMPS/AMPS networks.
Future releases will address the area of mobile-to-mobile and fixed-to-mobile covergence.
In describing Jambala's architecture and implementation, the author shows how the platform provides a unique combination of availability, reliability, scalability and Internet readiness, all based on commercially available hardware. He further explains how platform support for Java and CORBA technologies yields a flexible, high-value, platform-independent environment in which wervices can becreated as rapidly as the technoloht will allow.

Application platforms of different sizes and configurations are needed for building efficient and manageable intelligent network (IN) nodes. Operators must be able to expand these platforms smoothly and flexibly
in response to market needs. Sustaining network growth means ensuring that node growth can be scaled within broad limits, while at the same time maintaining the redundancy, reliability, and availability of performance that is required in network nodes. Tis must be done in a way that is cost-effective and compatible with future modifications, in order to provide support for operators' rapidly changing needs.

The principal features and benefits of Jambala are:

- a cost-effective solution;
- efficient, cost-effective operation, administration and maintenance (OA&M);
- zero system downtime;
- flexible and future-compliant architecture;
- multi-application support;
- open service-creation environment (SCE);
- support for convergence.

Commercial hardware

The application platform on wich Jambala is implemented consists of Ericsson's tel ORB operating system/middleware (Box B) combined with off-the-shelf hardware components:
- Two OA&M UltraSPARC 300 MHz processors;
- 200 MHz Pentium boards with 512 Mbytes RAM;
- Two 100 Mbit/s Ethernet switches;
- One CD-ROM drive;
- One 40 GB hard drive;
- One SS7/C7 stack;

Figure 1 shows a block diagram of the different components on the Jambala platform, some of the application it can run, and te external applications and operating systems with which Jambala can communmicate. Network nodes-such as a service control point (SCP) or a home location register/authentication center (HLR/AC), which require a high degree of scalability and must meet stringent, real-time, fault - tolerance requirements - are implemented directly in Jambala.

Other IN nodes with less strict performance criteria, such as service-creation environments (SCE) and service-management systems (SMS), can be implemented in off the - shelf operating systems and hardware.

These nodes can make use of the open CORBA 2.0 interface  to access resources and communicate with applications in Jambala.

Zero - downtime operation
To implement traffic - and memoryintensive network nodes, such as HLRs or SCPs, high levels of reliability, redundancy and availability must be built into the nodes. Jambala offers an extensive range of features that
satisfy these requirements:
- Automatic recovery from software errors
- Data fault tolerance and redundancy
- On-line backup
- Adaptive hardware configuration
- Smooth software upgrade
- n+1 hardware redundancy
- Hot-swap replacement
- Heograpical node redundancy

The execution environment provides mechanisms for handling faulty code and erroneous data that can lead to failures in execution. These mechanisms ensure automatic recovery from execution failure, or that execution is terminated without affecting network node operation.

The integrated database supports distributed transactions, thus providing fault tolerance by continuously replicating data. For example, HLR and SCP data is spread out over several processors, where it is partitioned, distributed and replicated as distributed transactions.. In the event of processor failure, traffic processes or OA&M processes in the nodes are automatically diverted, allowing the nodes to make use of replicated data in other

Box B TelORB
TelORB is a distributed operation system for large-scale, embedded (soft), real-time applications that require very high availability. This requirement can be met thanks to
- the Tel ORB operating system (OS) kernel with appropriate mechanisms;
- a reak-time database;
- software-configuration control;
- an associated development environment.
In addition, CORBA-compliant object request broker and a Java virtual machine run on top of TelORB

Features and benefits of TelORB

Execution environment-programs are executed in processes that
- are distributed over several processor;
- interact primarily by invoking remote operations.

Real-time, object-oriented database in primary memory-data is replicated at several physical processors. This configuration makes the system tolerant to hardware faults and serious software faults.

Software--configuration control--this ensures that the processes in the system execute on available processor resources, which is especially useful when hardware fails.

A separated management layer for TMN-like operaton and maintenance through an object model stored in the target system. The object model is displayed via a user interface on a workstation.

A driver concept that allows application-specific hardware to be used without having to modify the operating system kernel.

A built-in CORBA 2.0 - compliant object-request-broker core that supports the IIOP for inter-operability with other systems.

Run-time environments for C/C ++ and Java code.

A software-structuring model in which interfaces can be maintained as separate product items (which aids the development of large Software systgems). The model is supported by tools that- compile the source code in the structure;
- build load modules;
- collect information that is needed for configuring the target system.

In-service upgrades of software and hardware with little or no disturbance to operation. This includes the option of adding processors to increase capacity.

HLR and SCP data stored in the database is log-marked, which means it can be backed up on line at regular intervals. Backups can be made automatically by the operating system's backup scheduler, or initiated manually by a system administrator. Theapplication data is copied to the hard disk, where it is sorted into files in the partitioned backup archive of the file system. Because it is scaled to use additional hardware resources, the hardware platform configuration can eliminate any adverse effects that making backups might have on HLR or SCP performance.

When a processor board is added to the plarform, the platform configuration manager automatically reallocates data and processes to the new processor according to configuration data. The configuration manager monitors platform processors and trigers appropriate alarms should a failure occur. Moreover, if a failure is detected, the configuration manager will attempt to recover the faulty processor by automatically reloading processor data and processes with replicas kept in other processors. If these attempts fail, the configuration manager scarches its information to find an alternate configuration. The faulty processor's data and processes are then automatically reallocated to the processors defined in the alternate configuration, and the faulty processor is blocked.

Upgrading application software in Jambala does not require any system downtime. During an upgrade, the new version of application software coexists with the old version--the platform allows for concurrent execution of old and new software in the same processor. All software proscsses running while the upgrade takes place are allowed to continue using the old software, whereas all new processes are channeled into the new software.

Jambala offers n+1 redundancy for all processing elements, memory units, and signaling links contained in a network node, which means that a Jambala network node can have no single point of failure. The OA&M processor operates in hot-standby mode to ensure continuous OA&M system availability. The network's signaling links and processor boards operate in load-sharing mode --a highly suitable mode for distributing traffic and providing continuous high-capacity operation. The application platform can also be readily deployed in a configuration based on geographical redundancy, which ensures that network node failure resulting from, say, a natural catastrophe at the site of an HLR or SCP will not have an impact on overall network performance.

Linear scalability

Increasing numbers of wireless subscribers and predicted increases in cellular voice, data and services are pressing HLR and SCP vendors to offer solutions with scalavble memory, processing, and signaling capabilities. The Jambala platform offers a linearly scalable solution for all of these areas

Jambala's scalability allows operators to expand network nodes to accommodate traffic growth patterns. The HLR, for example, is used in areas where subscriber levels are high but where the number of active subscribers is relatively low, typically 25% to 40% of the total number. Where this ratio applies, operators can configure the initial system with tailored memory/processing capacity and a signaling capacity that matches the activity level. As the number of subscribers and subscriber activity increases, operators can expand the system in a cost-effctive way.

Internet-ready OA&M
Internet-based OA&M solutions are becoming more prevalent in the mobile-communication industry. Flexibility, platform-independence, low cost, and rapid application development are among the strongest drivers toward solutions of this kind. Jambala offers an OA&M solution using a telecommunications management network (TMN) model and a management information base (MIB). The features of this OA&M system include:
- a managed object view of node resources;
- a manager-agent system that performs node-resource operations;
- CCITT-based notification formatting;
- Common management information services element-based (CMISE) manager-agent interaction;
- CORBA-based alarm/notification service;
- alarm management functions;
- security management functions;
- performance management functions;
- system management functions;
- Web-based graphical user interface;
- oper SCE for the differentiation and customization of service

Communication with the OA&M agent takes place over an interface that is compliant with CORBA 2.0,
CORBA compliance is achieved by using inter-ORB (the general inter - ORB protocol, GIOP) together with with the Internet inter-ORB protocol (IIOP). The GIOP specifies a set of message formats and common data reqresentations for communicating with other ORB-based systems or nodes. GIOP messages are exchanged over TCP/IP networks by means of the IIOP, which allows the Internet/intranet to serve as a bridge that customer operating systems can straddle to perform on-line, on-site and remote OA&M operations. This gives operators a Web-based OA&M solution and the ability to develop and use new OA&M applications.

Java support
The Jambala platform contains an integrated, real-time Java virtual macine (Figure 10) that allows Java applications to be developed on or ported to the application platform. The SCP and associated wireless IN (WIN) services are examples of applications that have been developed in Java.

In addition, the built-in database provides an application program interface (API) that is compliant with the object database management group (ODMG), thus enabling application portability across different database management systems (DBMS). The API adds to the Java programming laguage the binding that Java applications need for interfacing directly with the database and for exploiting its strong reliability, availability and redundancy characteristics.

Support for convergence
Support for convergence is becoming increasingly important in a world of deregulation, new end-user demands, multiple network operators, and merging technologies. The key features of a convergence node are adaptability and flexbility; that is, the node's ability to reuse existing infrastructure and technology as well as to incorporate new developments and technologies. Jambala's Internet readiness and scalable support of real-time Java applications and multiple protocols make it an ideal mobile-to -mobile and fixed-to-mobile covergence node

One of the first applications to be implemented on the Jambala platform will be an HLR/AC for digital, advanced mobile phone service (D-AMPS). Operators will obwerve that the scalability of memory and signaling links offered by the new platform allow them to dimension the HLR/AC to match subscriber and traffic in their mobile network.

A WIN Phase 1-capable SCP (PN-3660,Figure 9) has also been implemented on the Jambala platform. This application uses the platform's distribution mechanisms to trigger WIN services in the SCP , a network node that is implemented using the Java virtual machine and the platform's built-in DBMS API. By using the Java virtual machine to implement the SCP, operators can also use JavaBean technology and commercially available software development tools (such as Java Studio) to design and implement end-user servvices. An important feature of JavaBean is its modular nature, which lends itself to reusability when operators create multiple services. For example, JavaBean provides the basic blocks that operators need to build WIN services.

By using JavaBean technology, operators can use commercially available design environments as SCEs, creating, implementing and customizing their own WIN services. JavaBean technologies provide a library concept of sorts,whose components can be used for customizing and enhancing end-user services. Furthermore, operators can use other technologies, such as push technologies, to remotely update and add to their JavaBean libraries. Because SCE/SMSs have less stringent real-time and fault-tolerance requirements than SCPs or HLRs, they can exploit the application platforms' ability to allow application to be run on other operating systems, as well as its capacity for interfacing with the platform's SCP via the CORBA 2.0 interface.

Future architecture
Since the architecture of the apllication platform is modular, each component in the system can be independently evolved and upgraded. Therefore, the evolution of the system is best discussed in terms of its individual components.

Processing capability
The processing system consists of several commercially available processor boards that can be replaced without affection system availability. Thus, operators can capitalize on innovations in processor technology that are gaining ground in the computer industry, thereby maximizing the price-to-performance ratio for node growth in their own networks.

Signaling capability
Te signaling system provides support for SS7 and C7 signaling. Because the system consists of commercially available network signaling products, operators can integrate improvements and upgrade the system in a cost-effective manner.

TelORB operating system/middleware
TelORB is a real-time, fault-toterant and scalable operating system/middleware solution. The ongoing in-house development of this product, which is supported by Ericsson's patnerships in the industry, insures that the product and its external interfaces will evolve in response to market demands.

OA&M support
The system's OA&M component will be the first commercial implementation of a TMN-based interface that is compliant with CORBA 2.0 IIOP. In addition, it can easily be integrated into other operation system; for example, those of new or established operators.

Jambala provides operators with a unique combination of cost-effectiveness, performance and scalabilety. It uses commercially available hardware, which ensures that its price-to-performance ration is second to nonein the industry.

The Tel ORB operating system gives the robust Jambala platform outstanding, realtime node performance, and Jambala's modular hardware design provides flexible scalability wihtin broad limits.

The combination of object-oriented design, Java support, and Internet readiness offered by the platform gives operators the versatility and flexibility they need to remain competitive as they enter the next century.

It's a Local Call
If you need a primer on just how quickly cyber technology evolves, consider Internet protocol (IP) telephony. A mere two years ago, critics were dismissing Internet telephony as little more than a toy for computer nerds. At the time, IP telephony --inwhich voice signals are transmitted over the Net--required users to speak into microphones on their PCs. Not exactly the most convenient way to old a conversation. Worse, since the voice signals travelled over the public Internet, the sound quality was, at best, spotty.

While IP telephony was initially targeted at the consumer market--driving long distance calling rates down to ridiculously low levels in deregulated markets--the service is now being packaged for corporate users. According to Heidi Bersin, senior vice-presi-dent at Clarent Corporation, a US-based IP telephony specialist, the first business applications for Internet communications will be the merging of voice onto corporate intranets for long distance call and faxes. Like consumers, business users should save a bundle wiht these services--some analysts say as much as 60 percent on overseas calls. Down the road, industry experts say Internet telephony should also dramatically cut costs on toll free numbers for company call centers.

But the killer IP telephony application for corporates may be jst around the corner. US - based oCen, which operates the largest managed Internet telephony network in Asia, has already begun beta testing a product called CommPortal.Accessed via a single graphical interface on a user's PC screed, CommPortal offers a suite of communications aplications--voice and fax messaging, unified messaging (consolidation of all your voice mail, e-mail and faxes into one mailbox), video conferencing, as well as the ability to hold real-time conversations with anyone on the network, Because these applications are transmitted via a managed IP system, they should be much cheaper than comparable offerings sent out over leased - line or standard phone networks.

James Courtney, COO at oCen, sees IP telephony as the future of business communications. "There is a merging of tecnoloty," he explains. "Finally, the barriers between phones and PCs are breaking down." For corporate managers tired of operating separate computer and telephone networks, the crumbling of those walls can't come soon enough.

Power to the board

At 23.5 x 57 millmeters wide and eight millimeters high ( one by two inches and 0.3 inches high ) , Ericsson 's Macrodens Power module is about the size of a pack of chewing gum. Essentially a DC to DC converter, the power module converter 24 or 48 volts into anywere from 2 to 10 volts. Widely used within the telecom industry , as well as in avionics and high-end computers , the MacroDens power Module comes in 40 varieties, with five to 10 new models introduced each year.
A phone for the tough

Not much can shock an R250 PRO. The Ericssonn mobile phone , due in the third quarter of 1999, is made for outdoor communications in tough environments. It is shock-, dust- and waterproof.

It was developed for use on GSM 900 an GSM 1800 networks and support both GSM phase2+techology and the GSM Pro system , combining the advantages of GSM phones with Private Mobile Radio ( PMR ) fuctionality.

Features include enhanced full rate ( EFR ) speech coding , data and fax capabilities , built-in speaker phone, automatic answer on group calls and push -to-talk functionality with loudspeaker.
The award-winning switch is on

It's blue, it's the size of a large notebook, and it can tackle the telephone traffic of an entire office.Even better , it can be set up to run across a local area network, the Internet, or a wide area network. This means you don't nneed separate wiring for your phone system ad you significantly reduce voice transmission costs between offices.

The WebSwitch 2000, was developed by Touch-Wave, which was recently accquired by Ericcson. Controlled from a PC running Windows95/NT or an ordinary phone with a flash key, the WebSwitch 2000 is an Internet-based PBX solution for office phone needs such as voicemail and call conferencing . The WebSwitch has won nine industry awards in the last 15 months.

Flow of Tigris solutions

Ok, so the Tigris MultiService Remote Access Platform won a "Hot Product of the yeat"award last year from Data Communications magazine. The question is, why ? Probablybecause Tigris delivers a scalable, carrier-class solution capable of supporting a variety of remote access and backbone
flow4.jpg (7611 bytes) communications technologies from a single chassis.The platform provides both dial-in add dedicated access as well as high-performance routing. This means Tigris can meet the needs of carrier and Internet services providers' customers while consolidating access lines , equipment and network management.

Tigris was developed by Advanced Computer Communications, now part of Ericsson 's Boston-based Datacom Network and IP Services.


WAP--The wireless application protocol
Christer Erlandson Per Ocklind

Today, the wireless network is mainly used for voice communication, where voice mail is the most popular value-added service. However, a new buzz word is increasingly being mentioned in the marketplace:WAP, which stands for the wireless application protocol. With the WAP, a new dimensionwill be added to the use of mobile phoned, through the introduction of new data-oriented mass-market service.

The authors discribe the WAP concept. its historical and technological backgound, and the widerange of applications offered by this new approach to wireless data communication.

The wireless application protocol (WAP) is a completely new concept. It provides data oriented (non-voice) services to the massmarket and is capable of benefiting ---any where and at any time ---farmore end-users than the personal computer.
The wireless application protocol is a global standard for all wireless systems .The number of WAP subscribers is expected to skyrocket in the next file years: from its debut in 1999 to about 800 aillion in the year 2003 (Figure 1 )

Estimated increase in the number of wireless
subscribers in the next five-year period.


The WAP stack
One of the objectives of specifying the wireless application protocal was to make the mobile phone a "first-class citizen" of the Internet. ^Therefore, it was only natural that an Internet-oriented appraoch
be adopted. As Figure 2 shows,the WAP stack is similar to the layers used in the Internet.
The following entities are defined in the wireless application protocol:

A comparison between the layered communication stack in the wireless application protocol and corresponding Internet hierarchy.

Can be compared to a standard Internet browser; for example, Netscape Navigator or Microsoft InternetExplorer.

WML Script (wireless markup language, specified by the WAP Forum), similar to JavaScript. The script provides a means of reducing airtime by enhancing the capability of the handset; that is,it enables the handset to process more information locally before sending it to the server.

Wireless telephony application/WTA interface
The telephony part of the wireless application protocol. Makes it possible to create call-control andcall handling applications; for example, the definition of call chains and various options when a callis received.

Content formats
Includes business cards, calendar events and so on.

A layered telecommunicaton stack Includes transport, security and session layers.

WAP applications
The wireless application protocol encompasses the entire wireless community. Examples of applications include :

Information retrieval on the Internet
    The wireless application protocol can be employed to reach information on the Internet.   However, the WAP browser can not be used in the same way as an ordinary " surfing tool, "  since the mobile phone sets some limits on input and out put capability, memory size, and so forth.

The " serviceman application "
    With a WAP -enabled mobile phone, servicemen on duty can access their company inventory to check  whether or not a spare part is avaliable and directly inform customers about the situation.  Of course, they can use te same application to order spare parts, and will immediately receive a confirmed  delivery date.

Notification applications
    By means of agents residing in servers, users can be notified of e-mail and voice mail message that  have been sent to them. They can interactively request that more information be sent to their phones,  or order a printout on a fax machine of their choice. 

    Users interested in buying or selling shares can define a buying/selling profile that shows, for example, what stocks they are interested in, and at what quotation they might be willing to buy or sell. When a specific quotation has passed a defined trigger value, the agent notifies them and asks if they  want to make a transaction.

Mobile electronic commerce
                                      3 ), and to tickets offices and  wagering systems.

                      Telephony applications
    A user can have access to services that handle call setup, in combination with other services provided  by a wireless operator. A typical example involves a menu ( Figure 4 ), defined by the user, that is displayed  for each incoming call. This menu allowes the user to decide whether to answer or reject the call, or to  forward it to another extension or to a voice-mail service.

Via her terminal, a user chooses a particular service, which is the same as instructing her terminal to download the" deck of cards " associated with that service. She then folows the directions fot the service, making selectionsand entering relevant information, as necessary. To finish, she enters a command and the requested action is carried out.

Optimized for wireless communication

    In addition to providing end-users with new services, the wireless application protocol has been designed  for the economical use of the resources avalible in te telecommunications network. Over the air interface,  communication is binary-coded so as to use the bearer services as efficiently as possible. Headers and parts of messages that are frequently sent are represented by figures. The original content  is then restored in the receiver.

Service management
    Deck of cards
    The handling of services is based on a " deck-of-cards " metaphor. A " deck " is sent from  the network to a user's terminal when he or she enters a command to invoke a service.  The user can then navigate through the complete deck to make a choice.  If te desired choice is not included in the deck, another deck can be requested by command. When the user has made his or her choice and entered the relevant command, the requested  action is performed or information is retrieved.
    Depending on the capacity of thhe mobile phone, the decks and cards can be cached in the phone ( terminal ) for future use.

Benefits and market opportunities
    Benefits to the content provider
    The content provider writers or creates content that be read practically anywhere.
    The content, which is avalible on a server, can be accessed from any wireless device almost anywhere on the globe.

    Benefits to the network operator
    Network operators can offer a new category of service to end-users. They can create new, unique  service, and provide access to services that are avalible on Internet.
    Operators can reduce their cost of customer services and Help Desks by providing acess to information  resinding on their networks. With te introduction of the wireless application protocol, they will also remotely  be able to tailor te mens and te interface of customers' telephones to further differentiate their services.
    End-uers benefits
    More and more people are using their PCs to retrieve information from global sources.  Many users have found increased possibilities of executing services on their fixed phones, around the clock using an interactive voice-response system. Now , even greater possibilities are facilities throught services based on WAP technology ( Figure 5 ). To make it practical to use a  phone for accessing services, the user must be able to personalize the services; for example, from a Web page.
    Thanks to wireless application protocol, end-users can access the following services, and many more, by  entering the relevant choice via their terminal:
stock exchange quotations;
inventory balance;
geographics information.

WAP technology will bring any number of services directly to your fngertips.

Challengers to the network operator

    In the world of new services and opprtunities, network operators are likely to meet new challenges. They run high-quality networks with good coverage as a basis for their business, but they must also  decide on the next step in developing their business: Should they remain pure network operators only, providing access to a multitude of new services, or shoul tey take an active part in provinding  the services themseleves?
    With the wireless application protocol, operators can choose to open up access to all sites on  the Internet, by allowing all universal resource locators ( URL ) to be accessed by their subscribers.  Or they can opt to exercise full control, solely allowing access to those sites that are included in a  service package.

Creating a service package

    Network operators can do everything themselves; for instance, developing all sorts of services and  bundling them in an atttractive fashion.It is doubtful whether anyone will choose to do so, however, since a wide varety of companies already offer sets of services wiith attractive content.
    The other extreme is to outsource all services to a partner that handles te services, including  subscriptions.
    To keep control and yet allow access to content that is already avalible on the Internet, operators  will negotiate directly with content providers , or with content brokes that providers an assortment of services. In addition, the opreators will have to introduce a service-management system that allows  end-users to select the services they want.

Mass market
    The wireless application protocol enables network operators and content providers to reach a mass  market. Although WAP-enabled phones have not yet been manufactured, there are today approximately 200 million subscribers using wireless devices. Looking less than five years ahead, this figure will  probably have risen to 700 or 800 million, and we have good reason to believe that te majority of      handsets in use will support the wireless application protocol.

The Ericsson view
    Ericsson holds firm to the belief that the wireless application protocol will be a major enabling  component in the telecom business, and is the obvious technology for providing data communication services to mobile phones. However, this process will not happen by itself. We are therefore doing our part to develop and offer WAP-supporting products to the market, and to make sure that there are     applications in need of them , in order to stimulate the use of the wireless application protocol. Recently, Ericsson launched its first two WAP produced: a generic service development kit and a  WAP gateway for GSM.

    Ericsson, in cooperation with Motorola, Nokia and Unwired Planet, has defined a new protocol  for wireless data communication. The wireless application protocol provides end-users with  new services in a wide range of application, such as information retrieval on the Internet, mobile  electronic commerce, and telephoy applications. At the same time it is designed for the economical  use of the resources avalible in today's telecom networks.
    The new wireless application protocol enables network operators and content providers to  reach a mass market.
    By combining the wireless application protocol and bluetooth--Ericsson's universal radio interface for ad hoc, wireless connectivity --we will have an even more powerful conncept.
