<P>PROBLEM TO BE SOLVED: To appropriately release PDN connection #1 when receiving user data for a UE which is under the control of an MME#1 and is in an idle state after the MME#1 recovers from suspension due to failure or the like. <P>SOLUTION: The mobile communication method comprises: a step in which reattachment to an MME#2 is started when a UE receives a paging signal; a step in which an MME#1 sends a "DDN Ack" message, which contains an "EPS Bearer ID#1" included in a "DDN" and a "Cause=Re-Attach Success" message (information indicating that reattachment processing has succeeded), to an S-GW#1 specified by an S-GW address #1 included in the DDN; and a step in which the S-GW#1 releases PDN connection #1, which corresponds to the "EPS Bearer ID#1" included in the "DDN Ack" message, between a P-GW#1 and the S-GW#1 upon receiving the "DDN Ack" message. <P>COPYRIGHT: (C)2012,JPO&INPIT |
