Problems solved by technology

[0008] Therefore, it can be seen from the above that the above-mentioned patent documents retrieved technically do not fully guarantee the network throughput and reduce the handover delay. In addition, the measures that may affect the network QOS such as service interruptions that may exist in the network are insufficiently considered, and there is no Considering that wireless terminals are actually accompanied by the laws of human activities
In the prior art, there is no technical means that can solve the above problems well at the same time, so there is an urgent need for a better WLAN handover technology solution in the LTE-WLAN environment

Embodiment Construction

[0016] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0017] An overlapping and converged LTE-WLAN network, such as figure 1 shown. The current WLAN has been deployed on a large scale. A WLAN usually contains hundreds to thousands of wireless access points (AP, Access Point). The coverage of a single AP is limited. Usually, it is necessary to deploy many APs to form a WLAN. An overlapping WLAN is formed, and then integrated with various heterogeneous networks, especially the integration of LTE networks, to form an LTE-WLAN network.

[0018] Different from traditional wired networks, WLAN mainly uses media such as radio waves or infrared and ultraviolet light for signal transmission.

[0019] Such as figure 2 As shown, the WLAN system consists of a wireless terminal or mobile node (Moblie ...

Abstract

The invention provides a method and a device for switching WLAN (Wireless Local Area Network) under intercommunication between LTE (Long Term Evolution) network and WLAN network, wherein three switching methods of switching communication between the current WLAN hotspot and any target WLAN hotspot, switching communication from the current WLAN hotspot to any target WLAN hotspot through the next WLAN hotspot most probably entering for switching and switching communication from the current WLAN hotspot to any target WLAN hotspot through the LTE network are provided, the communication switching from the current WLAN hotspot to any target WLAN hotspot can be realized by a wireless terminal or a mobile node under any condition, and no interruption of data transmission in the switching process is efficiently ensured, so that QOS (Quality of Service) and network throughput are guaranteed.

Description

technical field [0001] The invention relates to the field of handover and connectivity between communication networks, in particular to a WLAN handover method and device under intercommunication between LTE-WLAN networks. Background technique [0002] Wireless Local Area Network (WLAN) devices provide untethered freedom of mobility. WLAN uses wireless communication technology to establish a network within a certain local area, and is the product of the combination of computer network and wireless communication technology. It uses the wireless multiple access channel as the transmission medium, provides the functions of the traditional wired LAN, and enables users to truly realize broadband network access anytime, anywhere and at will. WLAN technology uses electromagnetic waves to send and receive data in the air, making computers on the network mobile, and can quickly and conveniently solve the problem of network channel connectivity that is difficult to achieve by wired me...
