Method and means for providing enhanced subscriber identity confidentiality during roming in a cellular radio communication system |
摘要 |
The present invention relates to a method and means for roaming in a cellular radio communication system with a pool of core network nodes, e.g. an MSC-pool (201). A Subscriber Identification Service Node (SISN) is used to handle roaming from a service area supported by a previous MSC/VLR (205) in the MSC-pool to a service area supported by a new MSC/VLR (303) arranged outside of the MSC-pool. The SISN (301) receives an identity request from the new MSC/VLR (303) and forwards it to the previous MSC/VLR (205). The SISN receives a response from the previous MSC/VLR and relays it to the new MSC/VLR. This means that the SISN helps the new MSC/VLR (303) to retrieve data from the right MSC/VLR within the MSC-pool (201).
