Arrangements and method in mobile internet communications systems

摘要

The present invention relates to a session control unit (16) for use in a communication network (11a) for providing wireless access to the Internet for mobile nodes (2). The communication network comprises one or several access routers (3) for wireless communication with mobile nodes and one or several anchor points (12a) for muting data packets to and/or from the mobile nodes via the access routers. The session control unit is arranged to allocate a session identifier to a mobile node (2) requesting access to the network, select an anchor point (12a) to route data packets to and/or from the mobile node, and communicate an IP-address associated with the selected anchor point to the access router communicating with the mobile node. The allocated session identifier is independent of the selected anchor point. The invention also relates to a method for providing session control to a communication network.
