Problems solved by technology

[0052] Embodiments of the present invention provide an MS handover method, system and device, which solve the problem of whether the MS's neighbor RS is suitable as an MS because the serving MR-BS of the MS's neighbor RS cannot obtain the information of the MS's neighbor RS in the prior art. The judgment of the potential target station is not accurate, which leads to the technical defect of MS handover performance degradation

Embodiment Construction

[0080] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments:

[0081] The embodiment of the present invention is mainly to enable the serving MR-BS of the neighbor RS of the MS to communicate with the RS, so that the serving MR-BS of the RS can obtain the relevant information of the RS, such as the MS related information maintained at the RS, Interference detection results, whether the RS suggests that the RS itself becomes a potential target station of the MS, and other relevant information. Based on the relevant information reported by the RS, the MR-BS serving the RS can better determine whether the RS is suitable for the potential of the MS. The target station, so that the MS serving MR-BS can more appropriately determine the potential target station recommended to the MS, thereby improving the MS handover quality and reducing the MS handover failure rate.

Abstract

The invention discloses a handoff method for MS, which comprises the following steps: a service multi-hop relay base station MR-BS receives auxiliary handoff information sent by RS; and the service MR-BS judges whether to recommend RS as an object station to a mobile station or not according to the auxiliary handoff information. The embodiment of the invention ensures that the service MR-BS obtains the relevant information from RS, so that the service MR-BS of MS can determine to better recommend a potential object station and the relevant information to MS, thereby improving the handoff quality of MS and reducing the failure rate of handoff of MS.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, and in particular to an MS handover method, system and device. Background technique [0002] With the continuous development of communication technology, the requirements for the access rate of the communication system are also increasing. In order to meet the requirements of the access rate, the communication system adopting the broadband wireless access (BWA) method has attracted more and more attention. According to wireless communication theory, the higher the transmission frequency, the faster the radio wave decays with distance. The working frequency of the 802.16e communication system is relatively high, so the coverage of a BS (Base Station, base station) is very limited. For this reason, the Relay task group of the IEEE 802 working group is establishing a multi-hop wireless relay communication system standard, so that the new system can support MS (Mobile Station) based ...
