Abstract: When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.
