Explain the call flow when Paging a Mobile for an Incoming Call? nishanth 24-May-2008 07:28:08 AMComments wareseeker.com/free-gsm-sms-call-flow Posted by crouse www.soft411.com/software/call-flow.html Posted by crouse Step 1 In the idle state the mobile monitors the paging channel to receive incoming calls. A General Page Message on the Paging Channel notifies an incoming call. BS->MS PCH: General Page Message MSG_SEQ = 1 IMSI_S = 9876543210 SERVICEJDPTION = 2 Step 2 The paged mobile sends a Page Response Message on the access channel.
