Is It Possible Or Desirable? These mobile users will have identical requirements and expectations to the fixed users, for on-demand applications of telecommunications requiring high bit-rate channels. It will be necessary for these fixed and mobile networks to interoperate in order to pass data, in real time and at high speeds, between their users.
But how far must this interoperation be taken? How much integration of the fixed and mobile network structures is needed? Here, a fixed network, B-ISDN, and a mobile network, UMTS, under development at the same time, are examined to see how well and closely they should work together in order to meet expected user needs.
Work already taking place on this is discussed. The aim of UMTS is to implement terminal mobility and personal mobility within its systems, providing a single world mobile standard.
UMTS must also support the traditional mobile services presently offered by separate networks, including cordless, cellular, paging, wireless local loop, and satellite services. This gives mobile users an importance ranking alongside fixed-network users.
UMTS is expected to be introduced within the next ten years, and integration with narrowband and broadband ISDN is possible in this time.
This would be incompatible with anything else. Services from all fixed networks would be passed through via gateways. This design-from-scratch method would result in highly efficient intra-network operation, at the expense of highly inefficient inter-network operation, high development cost, scepticism relating to non-standard technology, and slow market take-up.
True integration with fixed networks is not possible in this scenario. Given the drawbacks, this is not a realistic option, and it has not been considered in depth. Integration with and evolution from the existing Global System for Mobile telecommunication.
GSM is currently being introduced on the European market. This option has the advantage of using already-existing mobile infrastructure with a ready and captive market, but at the expense of limiting channel bit-rate considerably, which in turn limits the services that can be made available over UMTS.
Some of the technical assumptions of UMTS, such as advanced security algorithms and distributed databases, would require new protocols to implement over GSM. However, integrating UMTS and N-ISDN would require effective use of the intelligent network concept for the implementation of mobile functions, and modification to existing fixed network protocols to support mobile access.
Fewer restrictions are placed on the possible uses and marketability of UMTS as a result. For these reasons, integration of UMTS with B-ISDN has been accepted as the eventual goal for interoperability of future fixed and mobile networks using these standards, and this integration has been discussed in depth.
Flexible support of fixed, multi-party calls, to allow B-ISDN to be used in conferencing and broadcasting applications, has many of the same requirements as support for mobile switching, so providing common solutions to allow both could minimise the number of mobile-specific extensions that B-ISDN needs.Industry Acronyms.
