摘要

According to the invention in a first aspect, there is provided a communication device (114, 200) configured to form part of a telecommunications network and to carry out an access network discovery and selection function, ANDSF. The communication device comprises a receiver (204) configured to receive a request for access network policy information relating to a user equipment, UE, (100, 300) and current UE location data. The communication device comprises a policy information unit (214) configured to determine primary information comprising access network policy information for the UE based at least in part on the current UE location data. The policy information unit is further configured to determine secondary information specifying one or more further UE locations at which the UE should make a further request for access network policy information. The communication device comprises a transmitter (202) configured to transmit the primary and secondary information towards the UE.
