Claim of US Patent No. 11,071,137


1. A data transmission method applied to a base station, the method comprising:receiving a buffer status report (BSR) sent by a terminal, the BSR indicating an amount of data required to be transmitted by the terminal;
receiving information about a currently accessed wireless local area network (WLAN) access point (AP) sent by the terminal, the WLAN AP and the base station belonging to the same network operator;
determining, by the base station, an amount of data transmitted by the terminal to the base station through a long term evolution (LTE) network according to the received information about the WLAN AP using a standardized interface, wherein the amount of data transmitted by the terminal is determined by using a network parameter of the WLAN when the network parameter of the WLAN is changed and is acquired by the base station, wherein the network parameter of the WLAN that is used to determine the amount of data transmitted by the terminal when the network parameter of the WLAN is changed and is acquired by the base station comprises both a load and link quality; and
sending an Uplink Grant (UL Grant) to the terminal, wherein the UL Grant indicates the amount of data transmitted by the terminal through the LTE network, and the terminal is configured to determine the amount of data to be transmitted via the LTE network according to the UL Grant, subtract the amount of the data to be transmitted via the LTE network from the amount of the data required to be transmitted by the terminal to obtain an amount of data to be transmitted via a WLAN; and transmit data through the LTE network and the WLAN,
wherein the information about the WLAN AP at least comprises a WLAN AP identifier; and
determining the amount of data transmitted by the terminal through the LTE network according to the information about the WLAN AP comprises:determining a WLAN termination (WT) according to the WLAN AP identifier, the WT being configured to provide the network parameter of the WLAN to the base station:
interacting with the WT through the standardized interface to obtain the network parameter of the WLAN, and
determining the amount of data transmitted by the terminal through the LTE network according to a network parameter of the LTE network and the network parameter of the WLAN, the network parameter comprising the load and the link quality.
