Problems solved by technology

[0011] (1) The method of detecting and locating the ping-pong effect cell through the drive test instrument adopts a passive discovery mechanism, and the analysis range is limited;
[0012] (2) The method of analyzing and locating the ping-pong effect cell through the call signaling record of the A interface of the signaling monitoring system is subject to the user's call behavior, and the call whose call time is shorter than the judgment threshold will not be included in the analysis sample, which will lead to analysis accuracy reduce

Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0074] In one embodiment, such as figure 1 As shown, a method for analyzing and locating a ping-pong effect cell by Gb interface signaling comprises the following steps:

[0075] S1. Obtain the FLUSH-LL message sent by the SGSN, and when the SGSN finds that the mobile station is updating the cell or the routing area, it sends the FLUSH-LL message;

[0076] S2. Extract the relevant fields for analyzing the ping-pong effect sub-district in the described FLUSH-LL message, generate the FLUSH-LL process record table, the fields include start time, TLLI, SGSNIP, PCUIP, BVCI_1 and BVCI_2, the FLUSH-LL The TLLI values ​​of all records in the process record table are the same, and one of the records is shown in Table 1:

Abstract

The invention relates to a method for positioning a ping-pong effect cell by means of Gb interface signaling analysis. Packet domain core network Gb interface signaling is analyzed, and an algorithm for judging a ping-pong effect is designed, and the ping-pong effect cell is directly obtained. According to the invention, an active discovering mechanism is adopted, the ping-pong effect cell analysis based on FLUSH-LL signaling is realized, and the method for positioning the ping-pong effect cell by means of Gb interface signaling analysis has the advantages that the protocol stack is simple, the realization difficulty is low, the hardware cost is low, the accuracy of ping-pong effect cell analysis is high, etc.

Description

technical field [0001] The invention relates to a telecommunication operation system, in particular to a method for analyzing and locating a ping-pong effect cell through Gb interface signaling. Background technique [0002] In the GSM network, all handovers are hard handovers. When handover occurs, the mobile phone always releases the channel of the original base station first, and then can obtain the channel allocated by the new base station. It is a "release-establishment" process. A base station or sector is a competitive relationship. If the signal strength of the two base stations changes drastically in a certain area, the mobile phone will switch back and forth between the two base stations, resulting in the so-called "ping-pong effect". [0003] If there are ping-pong effect cells in the network, it will have an impact on the voice quality and data service quality. Therefore, the analysis and optimization of the ping-pong effect cells is one of the key points of th...
