Abstract
The invention discloses a determination method and a determination device of a time division-synchronization code division multiple access (TD - SCDMA) channel switch boundary. The method comprises the steps of collecting and saving switch signaling and position measurement information in real time, choosing a channel with the switch boundary not determined, determining switch events corresponding to the channel according to the saved switch signaling and finding out position measurement information before the switch events happen, dividing the peripheral region of the channel into sectors, finding out a sector to which each switch event belongs, deleting switch events with small probability of occurrence in each sector and averaging position measurement information corresponding to remaining switch vents in each sector to obtain an average switch point position of each sector, connecting average switch points of all sectors and a base station position corresponding to the channel in sequence to obtain the switch boundary of the channel, and determining a switch boundary of the next channel until switch boundaries of all channels are determined. The determination method and the determination device of the TD - SCDMA channel switch boundary is good in instantaneity and high in accuracy.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for determining a TD-SCDMA cell switching boundary. Background technique [0002] In the prior art, the method for determining the cell handover boundary of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is generally to use wireless network planning simulation software, based on wireless network basic data, service density distribution data and High-precision, high-accuracy maps, etc., use Monte Carlo simulation methods (random simulation and inductive statistics) to determine cell handover boundaries. [0003] This method of prior art has following several shortcoming: [0004] High cost: In order to improve the accuracy of the simulation, it needs to be based on a high-precision map, and the purchase cost of this map is relatively high. [0005] Poor real-time performance: With the continuous development of my country's economy...
