Claim Text:
1. In a wireless communication system in which a user equipment (UE) is being served by a first radio access network (RAN) entity, the first RAN entity having a respective coverage area, a method comprising: the UE receiving from the first RAN entity an indication of a size of the first RAN entity's coverage area; the UE calculating the UE's speed; the UE determining that the calculated speed exceeds a threshold speed, the threshold speed being based on the size of the first RAN entity's coverage area; in response to the UE determining that the calculated speed exceeds a threshold speed, the UE handing over to a second RAN entity; after the UE handing over to the second RAN entity, the UE entering a coverage area of a third RAN entity and receiving from the third RAN entity an indication of a size of the third RAN entity's coverage area; the UE conducting an additional calculation of the UE's speed; the UE determining that the additional calculation of the UE's speed indicates that the UE's speed has remained less than a second threshold speed for at least a threshold amount of time, the second threshold speed being based on the size of the third RAN entity's coverage area; and in response to determining that the additional calculation of the UE's speed indicates that the UE's speed is less than a the second threshold speed, the UE handing over to the third RAN entity.
