Step (4), eMME returns to the cluster switch failure information to source eNodeB;
Step (5), eMME initiates to create cluster S1 load bearing process, and to target eNode B signalling of bouquet handover request message;
Step (6), target eNode B are carried out to switch to admit and are controlled, and configure needed bearing resource and other relevant information, and to eMME signalling of bouquet switching request acknowledgement message;
It should be noted that, for step (6), if target eNode B not yet configures the Radio Resource of this cluster multi call business, target eNode B need to be shared Radio Resource for this group-calling service configurating downlink, and sends to eMME to get final product by the cluster switching request acknowledgement message configuration information of descending shared Radio Resource; If be configured the Radio Resource of this group-calling service in target eNode B, target eNode B only need to send to eMME to get final product by the cluster switching request acknowledgement message existing descending shared wireless resource configuration.
Step (7), eMME switches indication to source eNodeB signalling of bouquet, carries the wireless resource configuration of target eNode B;
Step (8), source eNodeB sends eNodeB state transitions message to eMME, and eMME forwards eNodeB state transitions message to target eNode B;
Step (9), after the monitoring users terminal is completed down-going synchronous with target eNode B, the cluster control channel data of receiving target eNodeB, complete the uplink synchronous with target eNode B, and complete handoff procedure to target eNode B transmission RRC connection reconfiguration message, at this moment, the cell-of-origin in eNodeB discharges and is connected with the RRC of monitoring users terminal.
Step (10), the cell-of-origin connects to the new measuring control information of monitoring users terminal transmission by RRC, remeasures according to new measuring control information for the monitoring users terminal.
