Embodiment Construction

[0047] A mobile handover method oriented to multi-user single-terminal coordination scenarios proposed by the present invention will be further specifically described below in conjunction with the accompanying drawings.

[0048]When establishing the terminal revenue function, the received signal strength (RSS) of the idle terminal, the channel quality between the idle terminal and the service terminal, and the degree of preference of different service types to the network are comprehensively considered, and the network parameters are normalized. Then, in order to ensure the business continuity of the handover process, reduce the handover delay, and realize the terminal pre-handover, a terminal prediction handover method based on network parameters is proposed. This method includes the initialization and update of the prediction function, which makes the handover judgment more accurate precise.

[0049] If there are n idle terminals (1≤i≤n) around the service terminal. accordi...

Abstract

The invention provides a mobile switching method aiming at multi-user single-terminal synergetic scenes. The method includes: designing a revenue function with a plurality of parameters to comprehensively evaluate idle terminals, and selecting several idle terminals with high revenues for serving; in consideration of that flexible relative positions among users results in quality dynamic change of channels among the idle terminals and service terminals, comparing revenues of the idle terminals to effectively avoid ping-pong switching; predicating network parameters to accurately predicate revenues of the idle terminals at the next moment, performing pre-switching, accurately selecting the idle terminals providing service transfer for the service terminals to reduce mistaken switching. Using the mobile switching method aiming at the multi-user single-terminal synergetic scenes can acquire high avenues, decrease user service packet loss rate and meet QoS (quality of service) requirements of users, and the method is simple and easy to implement and has bright application prospect.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a mobile handover method oriented to multi-user single-terminal cooperation scenarios. Background technique [0002] With the development of microelectronics, chips and information communication technology, human beings will gradually enter the era of ubiquitous network, and the edge of the network will undergo great changes. Wired or wireless way to achieve interconnection. Due to the development of information service bandwidth, diversified content forms, and intelligent service provision, higher requirements are put forward for various network terminals. Therefore, the increase of business types, the rapid growth of service quality requirements and the slow improvement of terminal capabilities have become a contradiction. [0003] At present, it is an objective reality for a user to have multiple terminals. It is not feasible to expect users to aba...
