MOBILE COMMUNICATION METHOD, MOBILE MANAGEMENT NODES, AND SERVING GATEWAYS
Document Type and Number:
WIPO Patent Application WO/2012/093531
Kind Code:
A1
Abstract:
This mobile communication method is for a mobile communication system, whereby, when MME#1 is restarted in a first state in which PDN connection #1, which includes one or multiple EPS bearer #1s, is established between a UE and S-GW#1 and P-GW#1, the system transitions to a second state in which PDN connection #1 is released between the UE and S-GW#1, and PDN connection #1 is maintained only between S-GW#1 and P-GW#1. The second state has a step in which, after MME#1 detects that the UE involved is being reattached, the UE is not paged when a DDN containing the IMSI of the UE is received.
