A method by a network node controls connectivity of UEs by identifying a group of UEs for communication with an application controlling parameters used by the UEs for operation in a vehicle platoon. 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.
