Switch judging method of mobile communication service and mobile communication system

Abstract

The invention provides a mobile communication service switching decision method. The invention is characterized in that the method comprises the quality of the signal channel measurement of the mobile station. The switching decision entity obtains the average value of the signal channel quality, and a plurality of base stations are selected as the candidate base stations according to the sequenceof the average value from the larger to the smaller, and the switching request signaling containing the mobile stable service request information is transmitted to the candidate base stations; the candidate base stations judges whether to be switched into the mobile station through the received mobile station service request information, if the candidate base stations can be switched, the candidate base stations can return back to the affirmative signaling and the sub-signal channel information required by the service; in the candidate base stations with returned affirmative signaling, the switching decision entity selects the largest average value of the signal channel quality as the target base station, and transmits the switching instruction to the base station; corresponding to the method, the invention also provides a mobile communication service switching decision system, and the system comprises: a measurement unit, a computing unit, a selection unit, and a judgment unit.

Description

technical field [0001] The present invention relates to a switching method in a mobile communication system, in particular to a switching method between an OFDMA (Orthogonal Frequency Division Multiple Access) mobile communication system and an SC-FDMA (Single Carrier Frequency Division Multiple Access) mobile communication system. Background technique [0002] In the mobile communication system, the network entities involved in the handover include: the serving base station of the mobile station, the base station of the adjacent cell of the mobile station, and the handover decision entity controlling the handover. The handover process is generally controlled by the handover decision entity, which can be located in the serving base station, or in the Radio Network Controller (Radio Network Controller) or the Access Gateway (Access Gateway), depending on the network structure used in the implementation of the mobile communication system. There are interfaces between the hando...

Problems solved by technology

However, since the target website does not know the channel quality requirements of each sub-channel of the mobile station, it can only allocate resources to it randomly

This random resource allocation increases the probability of the mobile station occupying a sub-channel in deep fading, which degrades the handover performance, that is, the access control performance is poor.
