In one aspect, network nodes maybe configured for improving predictability of application performance in a wireless communication system. A mobile network domain predicts an upcoming network event affecting a UE operating in the wireless communication system and notifies an application server (AS) providing an application service to the UE of the predicted network event.

The method controls connectivity for a UE in the group with a RAN node responsive to characteristics of the other UEs in the group. For each of the UEs the characteristic relates to functional operation of the UE with the application. Another method by an application server identifies the group of UEs, and identifies a characteristic of each of the UEs with the application. A message identifying the group of UEs and their characteristics is communicated to a network node for controlling connectivity for individual UEs in the group with a RAN node responsive to the characteristics of the other UEs in the group.
