Embodiment 1

[0071] Such as figure 2 As shown, a heterogeneous network cross-domain fusion switching method, the method steps are as follows:

[0072] Step S1: The mobile terminal connected to the heterogeneous network performs adaptive scanning on the currently connected wireless network and surrounding wireless networks, and uploads the collected data to the wireless access point;

[0073] Step S2: Each wireless access point within the control range of the centralized hub node periodically measures the network attribute data within its range, and uploads it to the centralized hub node;

[0074] Step S3: The centralized hub node performs service perception according to the data uploaded by the wireless access point, and performs handover pre-judgment;

[0075] Step S4: The centralized hub node performs service quality perception according to the network attribute data in the available network list, and selects the optimal network among the remaining networks for switching;

Abstract

The invention provides a heterogeneous network cross-domain fusion switching method, which comprises the following steps that: S1: a mobile terminal accessed to a heterogeneous network adaptively scans a currently accessed wireless network and surrounding wireless networks, and uploads collected data to a wireless access point; S2, each wireless access point in the control range of the centralizedhub node periodically measures network attribute data in the range of the wireless access point and uploads the network attribute data to the centralized hub node; S3, the centralized hub node performs service awareness according to the data uploaded by the wireless access point and performs switching pre-judgment; S4, the centralized hub node performs service quality perception according to thenetwork attribute data in the available network list, and selects an optimal network from the remaining networks for switching; and S5, the attribute data of the current connection network by the centralized hub node is periodically measured, the attribute data is kept unchanged if the performance meets the requirement, and otherwise, it is returned to the step S1 to execute.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a heterogeneous network cross-domain fusion handover method. Background technique [0002] With the development of communication technology, various wireless access technologies emerge as the times require, thus creating a new scenario where multiple wireless networks coexist. In this scenario, users need to perform vertical switching in various wireless networks, and heterogeneous vertical switching technology is required to ensure normal communication. Heterogeneous vertical handover mainly includes three stages: network discovery stage, handover judgment stage and handover execution stage. [0003] In the network discovery phase, users can search for available networks in the heterogeneous wireless network area. During this process, it is necessary to balance the network discovery time and terminal energy consumption. The shorter the network discovery...
