Abstract: A communication control method is a method for performing offload to transfer a traffic load of a cellular base station to an access point. The communication control method comprises a step of maintaining without releasing the first connection, by a user terminal that have established a first connection with the cellular base station, even when the offload is started after establishing a second connection with the access point; and a determining step of determining, by the user terminal, whether the offload is continued or canceled after the offload is started.

Abstract: A cellular base station is configured to execute functions of: a plurality of packet data convergence protocol (PDCP) entities corresponding to a plurality of bearers used in performing a communication with a user terminal in which the user terminal is configured to utilize radio resources of the cellular base station and a wireless local area network (WLAN) access point; and a specific entity that provides a PDCP packet with a header including a bearer identifier to generate a specific packet, the PDCP packet generated by each of the plurality of PDCP entities. The bearer identifier is for identifying a bearer to which the specific packet belongs, from the plurality of bearers. The specific entity transmits the specific packet to the user terminal via the WLAN access point.
