25.10.1 Process Subscriber_Present_VLR
The VLR invokes the process Subscriber_Present_VLR when the mobile subscriber becomes active. The general description of the short message alert procedures is in clause 23.4 of the present document.
25.10.2 Process SubscriberPresent_SGSN
The SGSN invokes the process Subscriber_Present_SGSN when it receives a Page response, a GPRS Attach request or a Routing area update request message (3GPP TS 24.008 [35]). The general description of the short message alert procedures is in clause 23.4 of the present document.
