Data transmission method and data transmission device under dual-mode networking

Abstract

The invention discloses a data transmission method and a data transmission device under dual-mode networking. A traditional wireless local area network (WLAN) or a traditional long term evolution (LTE) network is utilized by the data transmission method and the data transmission device under the dual-mode networking. On by utilizing a backhaul network of one of the two networks or by simultaneously utilizing the backhaul network of one of the two networks and a partial backhaul network of the other network, core networks of the two networks can be accessed, and therefore, up data is transmitted to core network equipment of the LTE network or the WLAN by the backhaul network, and down data sent by the core network equipment of the LTE network or the WLAN is transmitted to a dual-mode base station by the backhaul network. Only a network element in a transmission network needs to be slightly improved but a traditional core network framework does not need to be improved, and thus, the dual-mode networking of the WLAN and the LTE network can be realized by the unified backhaul network, so that the throughput of a system is effectively improved, the data transmission cost is reduced, and the effective coverage of indoor and outdoor wireless networks is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and device under a dual-mode network. Background technique [0002] At present, the LTE (Long Term Evolution, Long Term Evolution) network has attracted widespread attention due to its high data transmission rate, high spectrum efficiency, and flexible spectrum allocation. Since the frequency bands of the existing LTE network are concentrated in higher frequency bands such as 2.3GHz and 2.6GHz, using outdoor base stations in high frequency bands for indoor penetration will greatly reduce indoor coverage. [0003] WLAN (Wireless Local Area Network, wireless local area network) is a network widely used indoors. When there are many data services in the 4G network, it can play a role in offloading the data services of the 4G network. In terms of indoor coverage cost, WLAN technology is very mature, and the construction cost of WLAN network is far lo...
