Embodiment Construction

[0074] The method of the present invention uses the generated network information list to establish a connection with the target network access point that has the highest priority in the network list and has not established a connection each time; if the connection fails to be established, it will connect with the next The target network access point establishes a connection.

[0075] The method of the present invention will be described in detail below in conjunction with the accompanying drawings. Refer to FIG. 2 for the method steps of the present invention.

[0076] Step S201: the mobile node makes a handover decision, and obtains the information of its neighboring network access points;

[0077] Step S202: Establish a connection with a target network access point in the information of the surrounding neighbor network access points;

[0078] Step S203: If the establishment of the connection fails, the connection is established again with the target network access point t...

Abstract

The method comprises: the mobile node makes a switching decision and gets the information about its neighboring network access points; the mobile node establishes connection with one target network point in the list of its neighboring network access points; if the establishment of network connection fails, the mobile node establishes connection with other one un-connected target network access point in list of its neighboring network access points.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for switching between heterogeneous wireless communication systems. Background technique [0002] With the development of wireless communication technology, more and more wireless communication standards have realized commercial network operations, such as 802.11 / 802.15 / 802.16 wireless protocol standards of the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers), 2G, 2.5G Wireless communication standards and the 3G standard that will soon realize network operation. [0003] Wireless networks such as IEEE 802.11 / 802.15 have developed into microcells, and wireless networks such as 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), 3rd Generation Partnership Project 2 (3GPP2, 3rd Generation Partnership Project 2), IEEE802.16, etc. The network evolves into a...
