Abstract:
1. A radio access network (RAN) node apparatus of a mobile telecommunications network comprising: at least one processor; and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: receive a request message for initiation of a communications session with a mobile terminal serviced by the RAN node, wherein the request message comprises one of a packet data protocol (PDP) context initiation message and a session initiation protocol (SIP) message received from a serving general packet radio service support node (SGSN) of the mobile telecommunications network; determine a priority level associated with the communications session based on service information reflected by the request message, and determine that the priority level is pre-designated for high priority alerting; determine occurrence of a paging procedure timeout based on a lack of receipt of a response to a paging signal transmitted to the mobile terminal; and initiate a high penetration alerting procedure based on the paging timeout and the determination that the priority level associated with the communications session is designated for the high priority alerting, wherein the high penetration alerting procedure is configured for a higher probability of reaching the mobile terminal than that of the paging procedure.
