A method according to any of the preceding claims, wherein a forced selection of the service area identifier.
A telecommunications system, comprising:
- a plurality of service areas, each of the service areas being provided with a service area identifier;
- a location service node arranged to requests a service area identifier associated with a mobile station and to provide location information concerning the mobile station based on the service area identifier;
- and
- selection means that are arranged to select one service area identifier associated with the mobile station from a plurality of possible service area identifiers associated with the mobile station in accordance with at least one predefined rule for the selection of the service area identifier.
