Method and equipment for load balancing of heterogeneous network composed of cellular network and wireless local area network

Abstract

The invention aims to provide a method and equipment for realizing load balancing of a heterogeneous network composed of a cellular network and a wireless local area network. The method involves acquiring load information of a neighboring wireless local area network by cellular network access equipment, wherein the heterogeneous network is composed of the cellular network and the wireless local area network; according to the load information of the wireless local area network, determining the load condition of the wireless local area network; and according to the load condition of the wireless local area network, configuring user equipment corresponding to the wireless local area network to perform switching or routing, thereby achieving load balancing of the heterogeneous network. Compared with the prior art, the self-optimizing method for realizing load balancing of the heterogeneous network composed of the cellular network and the wireless local area network overcomes the problem of load unbalancing of the cellular network and the neighboring wireless local area network, does not need intervention of maintainers, provides relatively good user experience, controls and manages the wireless local area network based on the cellular network, and realizes self-optimization of the load balancing of the heterogeneous network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a technology for realizing load balancing under heterogeneous networks of a cellular network (Cellular Network, CN) and a wireless local area network (Wireless Local Area Networks, WLAN). Background technique [0002] Due to the wide available frequency spectrum and its extensive deployment, WLAN has become an effective method for load shedding in carrier networks. 3GPP (The 3rd Generation Partnership Project, third generation partnership project) has standardized the integration of wireless local area network and cellular network at the core network level. However, at the air interface level, cellular and WLAN still work independently. Also, the handover or routing between the cellular network and the WLAN is always initiated by the user equipment based on its own decision. [0003] Due to the passage of time and the movement of user equipment, different WLANs often hav...
