Method and arrangement in a communication network

摘要

Method and arrangement in a network control node, for performing access control of a mobile node in a handover from a source cell to a target subscriber group cell. The method comprises obtaining a network based allowed subscriber group list, receiving a target subscriber group identification, checking if the target subscriber group identification is comprised in the obtained network based allowed subscriber group list. If it is, information from a target network control node is obtained, verifying that the received subscriber group identification corresponds to the target subscriber group cell. Still further, the method comprises granting the mobile node access to the target subscriber group cell.;Also, a method and arrangement in a target network control node, for assisting a network control node in performing access control for a mobile node in a handover from a source cell to a target subscriber group cell is provided.
