ALLOCATING IDENTIFIERS TO COMMUNICATION DEVICES

摘要

A method of allocating a routing identifier to a subscription (FIG. 2) in order for an application server (218) to be able to send a message to or call a mobile terminal (108) comprising the steps of sending a request for the routing identifier from the application server to a subscription database (step 1); selecting a routing identifier (steps 2 and 3); using the request to create an association between the routing identifier and a subscription identifier in the subscription database (steps 2 and 3); and de-allocating the routing identifier once message sending or calling is complete (step 7).
