Claim of US Patent No. 10,485,053

1. A method for preempting simultaneous control plane (“C-Plane”) load collisions from simultaneous user equipment (“UE”) releases on a group call, the method comprising:determining, by an Evolved Node B (“eNB”), whether at least one of a plurality of UEs has data activity, wherein each UE in the group call is included in LTE cells that use an identical C-Plane processing pool;
determining, by the eNB, whether a simultaneous C-Plane UE release condition has been met for the plurality of UEs;
generating randomized values; and
setting, by the eNB, an inactivity timer countdown value for each of the plurality of UEs using the generated randomized values over a first time interval for the inactivity timer countdown value.
