A method for realizing automatic switching between td-scdma cellular network and wireless local area network in heterogeneous network

Abstract

The invention provides a method for realizing automatic switch between time division-synchronization code multiple access (TD-SCDMA) cellular network and a wireless local area network in a heterogeneous network. In the method, simple hardware update on a wireless terminal, a cellular base station and a wireless access point is made on the basis of an original network; and the automatic switch between the two networks is realized by only redesigning part of frames in the two networks and by certain flow control. The method comprises the following steps of: firstly, judging the network coverage situation of an area where a terminal is positioned and judging whether the area wherein the terminal is positioned has an available network through real-time detection of the signal strength of the two networks; secondly, judging the resource utilization situation of respective network and judging whether the network can provide an available channel for the terminal through the real-time detection of the frequency band resource remaining amount of the two networks; and finally, automatically selecting an available network for access according to detection results by the terminal.

Description

[0001] Technical field A method for automatically switching between a TD-SCDMA cellular network and a wireless local area network in a heterogeneous network belongs to the technical field of wireless communication networks, specifically, it relates to cellular networks, wireless local area networks, and both cellular networks and wireless local area networks. Design of frame formats under different network protocols. Background technique [0002] In the field of wireless communication, cellular network and wireless local area network are the two most mainstream wireless communication networks today. With the development of wireless communication technology, the amount of data generated by users in the communication process increases rapidly, and the requirements for data processing capabilities It is also getting higher and higher, but in the actual wireless communication network, it faces such a main problem: the cellular network has a wide coverage area, but its data throughp...

[0002] In the field of wireless communication, cellular network and wireless local area network are the two most mainstream wireless communication networks today. With the development of wireless communication technology, the amount of data generated by users in the communication process increases rapidly, and the requirements for data processing capabilities It is also getting higher and higher, but in the actual wireless communication network, it faces such a main problem: the cellular network has a wide coverage area, but its data throughput rate is low; while in the wireless local area network, its data throughput rate is very high, but Its coverage is limited

Although this method realizes free switching between the two networks, adding corresponding devices to the network link not only increases the cost of networking, but also increases the complexity of networking, and the Once a fault occurs, professional personnel are required to check the network, so that the problem cannot be solved in time
