LOCATION UPDATE IN A SUPER-CHARGED ENVIRONMENT

摘要

The present invention relates to a method and network entity for performing a location update in a Super-Charged environment of a mobile network, wherein a release message is transmitted from the mobile network to an old network entity having served a mobile terminal, in response to a location update request message received from a new network entity (31) serving the mobile terminal (1). A subscriber identity allocated to the mobile terminal (1) at the old network entity (30) is released or de-allocated in response to the receipt of the release message. Thus, even in a Super-Charged environment, the old network entity is informed of the fact that the mobile terminal (1) has left its service area, and may re-allocate the subscriber identity which has been allocated to the mobile terminal (1).
