Problems solved by technology

However, the handover method based on location information has certain requirements for the accuracy of location estimation. When the accuracy of location estimation is not high enough, for low-speed users, the width of the overlapping area of ​​the corresponding soft cell is small. The ping-pong effect based on location switching is generated due to the error of location estimation, that is, when th

Embodiment Construction

[0027] Hereinafter, further detailed description will be given by taking the handover method of the present invention applied to a layered soft cell wireless network system of a distributed antenna system as an example.

[0028] The switching method first needs to determine the threshold for classifying the speed type of the mobile terminal according to the performance of the speed estimation method and the position estimation method used in the space sampling process, and complete the judgment of the classification switching method. For the low-speed mobile terminal using the handover method based on signal strength, it is necessary to determine the system parameters required to complete its handover, such as handover threshold, hysteresis margin, and terminal receiving sensitivity (see Document 3: P.P.Gregory. "Trends in Handover Design," IEEECommun .Mag., pp.82-90, March 1996.). For a high-speed mobile terminal using a position estimation-based handover method, it is necess...

Abstract

A switch method that uses for the wireless mobile communication system, uses the switch method based on the position estimation to the high-speed mobile terminal, uses the switch method based on the position estimation to the low-speed mobile terminal, according to the characteristic of the bed soft plot and the different mobile speed of the mobile terminal when it switches, uses the pre-contract switch method of the position information assistant to the blur type terminal because the speed estimation error can not confirm the speed type. The invention can solve that the existing technology use same switch mode to process the different type mobile terminal, can not provide different switch quality of service assuring issue, ensure the user to get the continuous switch effectively.

Description

technical field [0001] The invention relates to switching technology of a communication system, belonging to the field of information technology. Background technique [0002] In traditional cellular networks, handover is mainly due to the fact that users may pass through multiple cells during their movement, and the use of wireless resources in each cell is independent of each other. In order to provide users with a continuous service, it is necessary to When the user moves to a different cell or when the communication quality cannot meet the user's requirements, the use of system resources is adjusted in time, which is the so-called handover. The main basis for handover is signal strength and channel quality. When the user's current receiving power is lower than a certain threshold, it will consider using other cells whose base station signal strength is higher than the receiving threshold to serve the user. When the quality of the channel currently used by the user cann...
