Method and apparatus for determining neighbor district base station scanning type of mobile terminal

Abstract

The invention provides a method and device for assuring adjacent area base station scanning type for a moving terminal, wherein the method for assuring adjacent area base station scanning type of a moving terminal end comprises the following steps: selecting a scanning type with highest priority level and a scanning type with lowest priority level from a plurality of scanning types according to the supporting condition of the moving terminal and a service base station to a plurality of scanning types, and assuring the scanning types of the adjacent base station according to the relative information of last scanning adjacent base station of the moving terminal and the scanning type with highest priority level and the scanning type with lowest priority level. The invention solves the problems that the moving terminal how to set adjacent area scanning type in the scanning request, which can reduce unnecessary scanning and correlation process according to actual condition, improve terminal scanning efficiency, and provides accurate and high-efficiency support for future switching when the base station rear stage network resource utilization ration is improved and is used as a switching preprocessing process.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for determining the scanning type of a neighboring cell base station for a mobile terminal. Background technique [0002] The IEEE802.16 standard has undergone a series of developments since 2001. 802.16d and its previous versions are dedicated to fixed broadband wireless access air interface standards. The 802.16e completed at the end of 2005 adds The support for mobility enables mobile terminals to switch and roam among different base stations. [0003] Handover is a basic requirement of a mobile communication system. As a preprocessing process of the handover process, the scanning process of adjacent cell base stations plays an important role in handover. According to the parameters obtained in the scan, when the signal quality of the serving base station is poor, the terminal can quickly switch to the neighboring base station with good quality to avoid the ter...

AI Technical Summary

Problems solved by technology

By solving the problem in the prior art that the terminal cannot set the scanning type of the neighboring cell base station according to the actual situation of the neighboring cell base station, the scanning efficiency of the terminal can be improved, the interaction process of the scanning request and the scanning response management message between the terminal and the serving base station can be accelerated, and the scanning process can be reduced. Unnecessary waste of time and background network resources of service base stations; at the same time, the channel parameters and ranging parameters of neighboring base stations with good signal quality can be obtained to the maximum extent, so as to better prepare for future handover
