Embodiment Construction

[0015] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0016] figure 1 Represent the network topology diagram of the GPRS network of the embodiment of the present invention, as figure 1 As shown, the BSS is connected to the SGSN through the Gb interface, the latter is connected to the GGSN through the Gn interface, and the GGSN is connected to the PDN through the Gi interface. In addition, the SGSN is connected to the SCDR reading device, and the Gn interface of the SGSN is connected to the data monitoring device. Both the reading device and the data detection device of the Gn interface are connected to the analysis server.

[0017] In order to obtain the cell ID of the user, the data monitoring device of the Gn interface captures the data flow of this interface on the Gn interface and analyzes it to form the flow record of each mobile phone, that is, the corresponding information between the ...

Abstract

The invention discloses a cell ID getting method at the moment of monitoring Gn interface, belonging to the field of communication technology. The method of the invention includes: a) corresponding information between a user and IMSI is obtained according to monitored data at the moment of monitoring Gn interface; b) SCDR on an SGSN is read, and corresponding information of a user, cell ID and IMSI is obtained according to the SCDR; and c) corresponding information of the user and cell ID is obtained based on the same IMSI according to the corresponding information of step a and step b. The method of the invention can be applied to GPRS and 3G network, and the cell ID of the user can be obtained by monitoring the Gn interface.

Description

technical field [0001] The invention relates to GPRS and 3G networks, in particular to a method for obtaining user's cell ID when Gn interface is performing data monitoring. It belongs to the field of communication technology. Background technique [0002] In GPRS and 3G networks (such as UMTS), the data monitoring of the Gn interface is of great significance to the maintenance of the wireless data network. Through the monitoring of the Gn interface, the detailed content, performance and error conditions of the user's data service can be obtained. Gn interface monitoring has the advantage of a simple monitoring interface, and only needs to be connected to the Ethernet interface to monitor the traffic of the entire network. However, currently the data monitored by the Gn interface cannot distinguish which cell the mobile phone sending these data is located in, and the cell information is the most important information for optimizing data services. Due to the lack of cell i...
