Abstract: A wireless device (“UE”) that is operable to communicate with a network node of a group communication services (“GCS”) network can receive first data from the network node over a first type of GCS transmission based on a first location of the UE in a network coverage area. The UE can detect that the UE has moved to a second location. Responsive to detecting that the UE has moved to the second location, the UE can transmit a message to the network node based on the second location. Responsive to transmitting the message to the network node, the UE can receive second data over a second type of GCS transmission that is different than the first type of GCS transmission.
