METHOD AND ARRANGEMENT, NODE AND ARTICLE FOR OPTIMIZED PS DOMAIN IN GAN

摘要

The present invention relates to methods and arrangements to optimize a Packet Switched domain of a Generic Access Network GAN that communicates with a Serving GPRS Support Node SGSN in the Packet Switched domain. The method comprises the following steps: Detecting in the Serving GPRS Support Node SGSN that GAN access is being used by a Mobile Station/ Subscriber MS. Performing communication between the Mobile Station/Subscriber MS and the Serving GPRS Support Node SGSN by using a light-weight version protocol, so that functionality that is unnecessary in GAN mode of operation is decreased.
