A system (100) for generating by an Access Network Discovery and Selection Function, ANDSF, access network discovery information, ANDI, for transmission to a User Equipment, UE (180), of a network subscriber. The system comprises an ANDI repository (110) storing for each of a plurality of access networks an ANDI data entry comprising ANDI for the respective access network. Each of the ANDI data entries is stored in association with: an access technology type identifier identifying an access technology type of the respective access network; a location identifier associated with a location of the respective access network; and an access network group identifier identifying a group of a plurality of groups of access networks, to which group the respective access network belongs. The system further comprises an ANDI generating policy repository (120) storing a plurality of ANDI generating policies, each said policy identifying one or more of the groups of access networks for use in generating, from the ANDI data entries in the ANDI repository, the ANDI for transmission to the UE (180). The system (100) also includes an association component (130) arranged to associate each of a plurality of network subscriber identifiers with at least one of the ANDI generating policies stored in the ANDI generating policy repository (120), and an identification component (140) arranged to identify the at least one ANDI generating policy corresponding to a network subscriber identifier associated with the UE (180). The system (100) further comprises an ANDSF component (150) arranged to apply the at least one identified policy to the ANDI data entries stored in the ANDI repository (110) to generate the ANDI for transmission to the UE (180). |
