RELEASE OF REMAINING ACTIVE SERVICES IN VPLMNS

摘要

A method and apparatus for releasing remaining subscriber activities through the use of a service termination command. A home public land mobile network (HPLMN) is informed of remaining activities by visited PLMNs (VPLMN) and interrogating PLMNs (IPLMN). The HPLMN sends a timer to the VPLMNs and IPLMNs in a MAP operation. If upon expiration of the timer the subscriber has remaining activities in the node, then the node sends an alert to the HPLMN. The timer may be based upon a fraud risk of the PLMN and/or of the fraud risk of the subscriber. Accordingly, the HPLMN waits for an alert from a particular node before sending a service termination to the node.
