COMMUNICATION CONTROL METHOD AND USER TERMINAL

摘要

A communication control method for performing an offload from a cellular RAN to a wireless LAN, includes a step of performing, by a user terminal, a network selection operation to select an appropriate access network with which a traffic of the user terminal is exchanged, from the cellular RAN and the wireless LAN on the basis of determination parameters. The determination parameters comprises at least one of: a cellular network status that is a network status concerning the cellular RAN; a wireless LAN network status that is a network status concerning the wireless LAN; a cellular radio link status that is a radio link status between the cellular RAN and the user terminal; and a wireless LAN radio link status that is a radio link status between the wireless LAN and the user terminal.

主权项

1. A communication control method comprising:
controlling a network selection operation to select, from a cellular radio access network (RAN) and a wireless local area network (WLAN), an access network with which traffic of a user terminal is exchanged; transmitting dedicated parameters from a first cellular base station to the user terminal by unicast, the first cellular base station included in the cellular RAN, the user terminal connected to the first cellular base station, and the dedicated parameters used for the network selection operation to prompt traffic steering between the cellular RAN and the WLAN; and transferring configuration information of the user terminal from the first cellular base station to a second cellular base station, in response to the user terminal performing a handover from the first cellular base station to the second cellular base station, the configuration information including the dedicated parameters.
