Mikka,

thanks for straightening me out <GGG>

However, in that report I felt there wasn't alot of meat. More like a bunch of hand waving.

<< Research in the UK was non-conclusive apart form Vodafone saying there was no financial incentive to go the GSM-cdmaOne overlay route. Chaz, my comment is "I didn't write it!" >>

For Chaz. <g>

This was what was "officially" written re the 1997 Newbury trials:

* The stated objectives of the trial were:

>> Demonstration of and gaining experience in CDMA wireless access on a GSM
network.

Assess the ability of the GSM network to support an alternative air-interface for 3rd generation.

Testing of Globalstar key concepts; particularly use of the A-interface, GSM SIM and GSM authentication. <<

* The stated conclusions drawn from the trial:

>> This trial has demonstrated the technical feasibility of the GSM-CDMA concept through:

· Integration of a CDMA BSS with a core GSM switching (MAP) network using the
standard A-interface. Phased integration of the CDMA BSS and GSM MSC was
completed to test compatibility at MTP and BSSMAP levels.

· Validation of the performance of the CDMA air-interface when integrated to the GSM network. A set of radio performance tests were completed. The tests included coverage and soft-handoff in a standalone CDMA network, with further confidence and performance testing following integration.

· Demonstration of stable and reliable GSM services. The trial demonstrates that the GSM-CDMA concept supports supplementary services such as call forwarding, call waiting, call hold, and the short message service. Set-up time and failure rate tests show these services are stable and reliable.

· Demonstration of a security feature with the GSM authentication algorithm. The trial supports GSM authentication, which is part of GSM Mobility Management, using the same algorithm, SIMs and Authentication Centre as used in the operational GSM network.

This research trial has achieved the agreed objectives that were set at the start of the project, namely:

· It has demonstrated and provided experience using a CDMA wireless access on a GSM network. A CDMA BSS has been integrated at a standard A-interface, and experience was gained on the flexibility of the interface for third generation.

· Test Globalstar key concepts. The Globalstar system design relies on integration at the A-interface, use of the GSM SIM and of GSM style authentication, all concepts being demonstrated by the trial.

Although the scope of the trial did not include further third-generation topics, such as intersystem handover, both companies believe this has been a successful collaboration with valuable lessons for third generation implementation. <<

So no GSM-cdmaOne overlay's but we have Globalstar as a consequence.
