Attachment, handover, and traffic offloading between 3GPP RANS and Wi-Fi RANS

摘要

A source base station supports a 3GPP radio access network (RAN). The source base station determines that a data session between a user equipment (UE) and a Wi-Fi RAN associated with the source base station needs to be handed over. Based on the determining, the base station transmits a request to a target base station that supports a 3GPP RAN to determine a current Wi-Fi service capability of the target base station, and receives a response that indicates the current Wi-Fi service capability. The source base station transmits a handover request to the UE, based on the response, requesting that the UE handover the data session to one of: the 3GPP RAN of the target base station; or a Wi-Fi RAN associated with of the target base station. A UE and/or target base station may have similar and/or corresponding features.
