ACCESS NETWORK DISCOVERY AND SELECTION FUNCTION, ANDSF, NODE DISTRIBUTING CLOSED SUBSCRIBER GROUP, CSG, INFORMATION

摘要

The invention relates to a method in an Access Network Discovery and Selection Function, ANDSF, node for distributing Closed Subscriber Group information. The CSG information comprises an Allowed CSG List of a first UE and cell information indicating position of a cell with controlled access associated to the Allowed CSG List. The method comprises retrieving an Allowed CSG List of the radio cell from a CSG Database over a first network 10 interface (CSGi) between the ANDSF node and the CSG Database. Furthermore, the ANDSF node triggers the first UE to establish a connection to the ANDSF node over a second network interface (ANDSFi) between the ANDSF node (90) and the first UE. In addition, the ANDSF node receives cell information indicating the position of the cell with controlled access and the Allowed CSG List is sent to the first UE.
