Release with redirect to LTE

摘要

A Radio Network Controller (RNC) and method in a non-Long Term Evolution (non-LTE) radio access network for controlling a Release with Redirection (RwR) procedure in which a User Equipment (UE) operating in the non-LTE radio access network is released and redirected to an LTE radio access network. When the RNC detects that the UE has been inactive for a defined period of time, and the UE is capable of operating in the LTE radio access network, the RNC determines whether the UE will have adequate signal quality to operate in the LTE radio access network. If so, the RNC performs the RwR procedure to release the UE from the non-LTE radio access network and redirect the UE to the LTE radio access network. If not, the RNC performs a normal release procedure.

1. A method in a Radio Network Controller (RNC) in a non-Long Term Evolution (non-LTE) radio access network for controlling a Release with Redirection (RwR) procedure in which a User Equipment (UE) operating in the non-LTE radio access network is released and redirected to an LTE radio access network, the method comprising:
detecting by the RNC, that the UE has been inactive for a defined period of time; in response to detecting that the UE has been inactive for the defined period of time and when the UE is capable of operating in the LTE radio access network, determining by the RNC, whether the UE will have adequate signal quality to operate in the LTE radio access network; and performing by the RNC, the RwR procedure to release the UE from the non-LTE radio access network and redirect the UE to the LTE radio access network only upon determining that the UE will have adequate signal quality to operate in the LTE radio access network.
