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

Abstract

The invention discloses a method for realizing heterogeneous fusion of cellular network-wireless local area network, comprising: embedding a cellular network terminal module in the network access point of the original wireless local area network to form a new network access point; A communication connection is established between the access point and the network control unit of the cellular network through the cellular system, which is only used to transmit signaling related to network management; through the signaling, the new network access point is set as a network control unit. The subordinate unit of the unit, which is set as the same layer site of the cellular base station, is managed by the network control unit. The invention also discloses a cellular network-wireless local area network heterogeneous fusion system and device. Through the present invention, the position management and heterogeneous switching of the dual-mode terminal between the network access point of the wireless local area network and the cellular base station of the cellular network are realized, thereby realizing good heterogeneous fusion of the cellular network and the wireless local area network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system and device for realizing heterogeneous fusion of a cellular network and a wireless local area network. Background technique [0002] In recent years, with the widespread use of portable devices such as mobile phones and notebook computers, people have put forward more and more demands for mobile Internet access. 3G (WCDMA, CDMA2000, TD-SCDMA) systems 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. For example, a cell in the current WCDMA system can only provide a data rate of 2Mbps, which is far from meeting the user's demand for Internet services. By adopting high-speed downlink packet access technology (HSDPA, High Speed ​​Downlink Packet Acce...

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

[0006] figure 1 The problem of the heterogeneous fusion solution under the architecture is: when the dual-mode terminal enters the cellular network from the wireless LAN, the signal of the wireless LAN may suddenly weaken or disappear, which will make the dual-mode terminal unable to achieve heterogeneous switching normally. , resulting in the termination of the current transmission service; and when the dual-mode terminal enters the wireless local area network from the cellular network, it will need to re-authenticate the terminal, resulting in a large access delay

Therefore, this heterogeneous fusion solution is difficult to be recognized by users in practice, and it cannot meet the needs of users for heterogeneous fusion services.
