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

Abstract

The invention discloses a method for heterogeneous integration of a cellular network and a wireless local area network. The method comprises the following steps of: embedding a cellular network terminal module in a network access point of the original wireless local area network to construct a new network access point; connecting a dual-module terminal with the cellular network terminal module embedded in the network access point through the cellular network for communication; and exchanging a signaling related to heterogeneous network management to realize the heterogeneous integration of the cellular network and the wireless local area network. The invention also discloses a system and a device for the heterogeneous integration of the cellular network and the wireless local area network. With the adoption of the method, the system and the device, the heterogeneous integration of the cellular network and the wireless local area network can be realized in no need of changes on a core network in a cellular communication system center, and the scheme for the heterogeneous integration has the advantages of low implementation cost and fast implementation period.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and device for 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 Access...

Problems solved by technology

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

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

One is: the performance of its heterogeneous switching cannot be guaranteed, for example: when the dual-mode terminal enters the cellular network from the wireless LAN, the signal of the wireless LAN may suddenly become weak or disappear, which will make the dual-mode terminal unable to realize normally Heterogeneous handover cannot meet the needs of users for heterogeneous fusion services; second, such a solution may also require certain upgrades and changes to the core network of the cellular network, although this technical upgrade does not need to be like the 3GPP solution Increase core network equipment on a large scale, but it will also expose operators to operational risks
