1. A method comprising:
- receiving in an uplink message a first list of closed subscriber group identities for cells which are neighbors to a network access node;
creating a third list by checking the first list received in the uplink message against a second list which is a user equipment'"'"'s list of allowed closed subscriber group identities; and
sending the third list downlink to at least the network access node which provided the first list.

Abstract
A core network (MME or RNC for example) receives in an uplink message a first list of closed subscriber group (CSG) identities for cells which are neighbors to a network access node. The core network creates a third list by checking the first list received in the uplink message against a second list which is a user equipment'"'"'s list of allowed CSG identities; and then sends the third list downlink to at least the network access node which provided the first list. In different embodiments the neighbors of the first list include only cells which are direct neighbor CSG cells; or alternatively is also has cells which are adjacent to the direct neighbor CSG cells.
