Method and device for paging message group packets

Abstract

The invention discloses a method for paging message group packets. The method comprises the following steps that a BSC (base station controller) receives paging messages sent by a MSC (mobile switching center); and the BSC carries out group packet processing on the paging messages. Through the embodiment of the method disclosed by the invention, the BSC carries out group packet processing on the paging messages from the MSC according to cells or sites, the paging messages subjected to the group packet processing are sent to a base station, the total length of the paging messages and the sending number of the paging messages on paging links are reduced, and the load of down links for issuing the paging messages is effectively reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for grouping paging messages. Background technique [0002] With the development of mobile communication technology, GSM (Global System for Mobile Communications, Global System for Mobile Communications) network system has become the most widely used wireless communication system in the world today, and the number of users of this system is still increasing. The network element deployment of the existing GSM system is as follows: figure 1 shown. figure 1 Among them, the interface between BSC (Base Station Controller, Base Station Controller) and BTS (Base Transceiver Station, Base Transceiver Station) is called Abis interface, and the interface adopts LAPD (Link Access Protocol on the D-Channel, D-channel on Link Access Protocol) communication protocol. Abis interface protocol stack such as figure 2 As shown, among them, BTSM (Base Transceiver Stat...

Problems solved by technology

[0006] A big disadvantage of this existing paging technology is that under the current paging signaling process, the paging message is sent to each cell at the BSC, which makes the downlink load of the link transmitting the paging message on the Abis interface very heavy , seriously affecting the stability and business reliability of the BSC system

Especially in peak hours of traffic or network conditions where traffic volume increases instantaneously, it is likely to cause congestion in the downlink of the BSC sending paging messages, and a large number of paging messages will be discarded, which in turn may cause MSC to The same user resends a large number of paging messages or initiates network-wide paging, which may cause further congestion on the downlinks of the Abis interfaces of all cells in the current location area, resulting in a decrease in BSC traffic capacity, and the called service may even be completely blocked. Can't be done

[0007] Therefore, the disadvantages of the prior art are: the downlink load of the Abis interface to transmit paging messages is heavy, which easily leads to the downlink congestion of the Abis interface, the BSC traffic capacity decreases, and the called service is not smooth
