Method, system and device for realizing heterogeneous convergence of cellular network and wireless local area network

Abstract

The invention discloses a method for realizing heterogeneous convergence of a cellular network and a wireless local area network. The method comprises the following steps that: a terminal module of the cellular network and a terminal module of the wireless local area network are combined, such that an intermediate connection site is formed; the intermediate connection site is put in an overlaid coverage area of a cellular base station and the wireless local area network; the terminal module of the wireless local area network of the intermediate connection site is communicated with a network access point of the wireless local area network through connection of the wireless local area network; the terminal module of the cellular network of the intermediate connection site is communicated with a dual-mode terminal through connection of the cellular network; due to dual-connection of the intermediate connection site, the dual-mode terminal is communicated with the network access point of the wireless local area network; signalling related to management of a heterogeneous network is switched; and thus, heterogeneous convergence of the cellular network and the wireless local area network is realized. Heterogeneous convergence of two networks can be realized without changing a core network in a cellular communication system; and the advantages of being low in cost and rapid in period can be realized.

Description

[0001] This application is a divisional application, and its parent case is a patent application with an application date of September 7, 2011, an application number of 201110264346.9, and an invention title of "Method, System and Device for Realizing Heterogeneous Convergence of Cellular Network-Wireless Local Area Network". technical field [0002] The present invention relates to the field of wireless communication, in particular to a method, system and device for realizing heterogeneous fusion of cellular network and wireless local area network.

Problems solved by technology

The 3G (WCDMA, CDMA2000, TD-SCDMA) system can provide users with a certain amount of communication traffic for surfing the Internet, but it is difficult to meet the needs of mobile phone users for large data traffic on the Internet, and it is also difficult to provide users with high-speed data services

The 3GPP solution needs to be implemented by upgrading the equipment of the core network of the cellular network, which will face disadvantages such as high equipment cost and long commercial implementation cycle

The disadvantages of this solution are: compared with the wireless local area network, the cost of deploying HomeNodeB is expensive, and it is not easy to promote; and both indoor and outdoor base stations use the frequency band of the cellular network, and there will be interference between the two base stations, which will affect the performance of the system
