The invention comprises a method for establishing a signaling connection with a mobile station, which method is particularly applicable to third-generation mobile communications networks. A database is created at a node of a mobile communications network, and a mobile station connected with the network sends to said database information about all its subscriber identities (403). In the database, information is added (404) to the subscriber identity information which may be useful when said mobile station is paged (410, 411). Such contactability information includes e.g. the mobile station's location information, information about existing signaling connections and information about the primary paging channel monitored by the mobile station. The contactability information is updated according to changes detected in the status of the mobile station (406). The database will be discontinued for a mobile station that has had no connections for a predetermined time. The method reduces paging channel load in cells, reduces the need of mobile stations to listen to paging channels and makes radio access networks connections to multiple core networks more practical. |
