METHOD FOR SIMPLE RETRIEVAL OF NETWORK ACCESS SELECTION INFORMATION.

摘要

The invention relates to a method and system for network access selection comprising an Access Selection Server (ASS) (113) being arranged in a communication network comprising at least one User Equipment (UE) (109) and communication nodes. The ASS (113) collects (127) access selection information used in the network for the selection of network access for the UE (109) in a multi-access environment to a Packet Data Network Gateway (PDN GW). The network access enables a traffic bearer (116) between the UE (109) and the PDN GW for the traffic flow between an application (AP) (115) in the UE (109) via the PDN GW to a first node. The method and system is particularly characterized in that an Access Selection Client (ASC) (118) arranged in the UE (109) performs activation of new network accesses and/or selection, modification or deactivation of existing network accesses on the basis of the access selection information in order to enable the traffic flow (116). The selection/activation/modification/deactivation of the network access is triggered by a socket request sent from the application (AP) to the ASC (118) for the purpose of establishing means for end-to-end communication the traffic bearer (116).
