PACKET RADIO NETWORK FOR ACTIVATION OF A PACKET DATA PROTOCOL CONTEXT

摘要

A packet radio network provides a facility for communicating internet packets to and/or from a mobile user equipment. The packet radio network comprises a gateway support node, a serving support node and a radio network part. In response to a packet data protocol activation request message requesting a common packet data protocol context, the serving support node is operable in combination with the gateway support node to establish a common packet data protocol context in association with a packet communications bearer. The common packet data protocol context is established to communicate internet protocol packets via the packet communications bearer according to an internet protocol version specified by the mobile user equipment for one or more communications sessions. The common packet data protocol context therefore provides more flexibility, because a mobile user equipment can send both IPv4 internet packets and IPv6 internet packets as specified by the mobile user equipment. Furthermore a packet radio network according to example embodiments is provided with an arrangement for sharing the same GPRS/UMTS session, using a common packet communications bearer including the high-speed broadband radio bearers.
