A Realization Method of Micro Cell Pre-handover Based on Time Slot Calculation

Abstract

The present invention discloses a method for implementing micro cell pre-handover based on time slot calculation, which includes the following steps: step S1, pre-defining N period is the number of time slots in one frame, and is used to calculate the detection time slot of the MS position, wherein, the first bit time slot N of each frame period 1 and the third bit slot N period 3 is the detection time slot, and other time slots are used to send data; Step S3, through the first time slot N of each frame period 1 and the third bit slot N period 3. Determine the position of the terminal: pos 1 =x 1 +y 1 *j,pos 2 =x 2 +y 2 *j, and get the moving speed v: where t 0 is the time interval of a time slot. The present invention is applied to a communication system with an indoor or micro-cell structure, including multiple communication access points APs and mobile terminals MSs. Through an efficient switching algorithm, it realizes simple calculations and significant gains in reducing overhead, and achieves a high accuracy rate in The frequent handover communication mode under the micro cell structure reduces the handover overhead and redundancy of the communication system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication handover, in particular to a method for implementing micro cell pre-handover based on time slot calculation. Background technique [0002] The communication radius of an AP in a WLAN is generally less than 100 meters. In order to cover a relatively large area, a large number of APs must be deployed. In many cases, because a wireless connection client needs to move, when the user gradually leaves the range of a certain AP, its mobile terminal (MS) should switch to another AP within a short time. Handover directly determines the user's communication quality of service (QoS), because if the handover cannot be completed or the handover delay is too long, the user's communication, especially some sessions with strong real-time nature, will be affected or even completely interrupted. [0003] The communication coverage of each AP in this system is small, and there are overlappin...

Problems solved by technology

[0003] The communication coverage of each AP in this system is small, and there are overlapping areas. The mobile rate of MS in the system is not high, but the mobile frequency is high. Due to the small coverage of AP, the mobility of MS is strong, so MS needs to switch between different APs.
