Abstract

The object of the present invention is to provide a method and equipment for realizing load balancing in a heterogeneous network of a cellular network and a wireless local area network. Wherein, the cellular network and the wireless local area network constitute a heterogeneous network; the cellular network access device acquires load information of an adjacent wireless local area network, and determines the load status of the wireless local area network according to the load information of the wireless local area network; according to the The load status of the wireless local area network is configured, and the user equipment corresponding to the wireless local area network is configured to perform switching or routing, so as to realize load balancing under the heterogeneous network. Compared with the prior art, the present invention proposes a self-optimization method for realizing load balancing in a heterogeneous network of a cellular network and a wireless local area network. Manual participation, better user experience, control and management of wireless local area network based on cellular network, realize self-optimization of load balancing of 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...
