Data transmission method, terminal and network device

Abstract

The invention provides a data transmission method, a terminal and a network device, relates to the field of communication, and solves the problems that in the prior art, when a network side WLAN device and a terminal working in an unlicensed frequency band are accessed to a channel, the CMSA must pass through, the realization complexity is high, and the interference elimination effect is poor. Themethod is applied to a terminal and comprises the following steps: acquiring first data which needs to be sent to network equipment through a first wireless access network; wherein the first wirelessaccess network works in an unlicensed frequency band or a shared frequency band; and sending the first data to the network equipment through the second wireless access network. According to the scheme provided by the invention, the second wireless access network is used for sending the data which should be sent through the first wireless access network. According to the embodiment of the invention, the resource competition between the terminal and the network equipment is avoided, so that the network equipment does not need to depend on CSMA and other channel sharing technologies to access the channel or the complexity of the channel sharing technology is reduced, the equipment realization complexity is reduced, the same-frequency interference can be effectively removed, and the channel utilization rate is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, terminal and network equipment. Background technique [0002] At present, 3GPP supports a variety of LTE (Long Term Evolution, long-term evolution) and WiFi (Wireless Fidelity, wireless fidelity) offloading data technologies, including offloading data from the core network to WiFi and from the radio access network (RAN, Radio Access Network) The data is distributed to WLAN (Wireless Local Area Networks, wireless local area network). The WLAN can be connected to the PGW (Packet Data Network Gateway) of the core network in a trusted or untrusted manner, and the PGW offloads part of the data from the core network to WiFi. The RAN-level LTE and WLAN aggregation (LWA, LTE and WLAN Ran Level Aggregation) technology of 3GPP R13 can support LTE base stations to offload some traffic to WLAN for transmission to UE. In this technology, the LTE eNB offloads par...
