Embodiment Construction

[0036] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Based on above-mentioned purpose, technical scheme of the present invention realizes as follows, comprises:

[0038] The mobile terminal initiates a scan to the serving base station. When setting the scanning type of the neighboring cell base station, the mobile terminal should consider the support of the scan capability of itself and the serving base station (completed through the basic capability negotiation process of access), the channel quality of the neighboring cell base station, and the historical scanning Type and association result to determine the scan type of neighboring cell base stations.

[0039] Wherein, the channel quality of the adjacent cell base station includes: signal-to-noise ratio (CINR), signal strength (RSSI), and relative time delay (RTD), etc.; the history scanning type of the adjacent cell base ...

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...
