Abstract
The invention disclose a paging method of a secondary system of a base station of a global mobile communications system, the method comprises the following steps: first, organizing an integral paging information to send to each BTS site of each transmitting and receiving table of each base station after a base station controller BSC receives the paging information of an A hole or a Gb hole, second, the BTS sites are distributed to each district after the BTS sites receive the integral paging information according to district information which is allocated by the BTS or district listing in the integral paging information, and paging information of a Um hole is finally generated, and a mobile station is paged. Compared with the prior art, the invention can release the paging processing bottleneck of the BSC, and can greatly saves communication bandwidth of an Abis interface.
Description
Technical field
The present invention relates to GSM (Globe System for Mobile Communications, global system for mobile telecommunications) system, relate in particular to the method for BSS in a kind of gsm system (base station sub-system) paging.
Background technology
Under the background that communications industry develops rapidly, the number of users of global system for mobile telecommunications network increases fast, and the demand of the disposal ability of the network equipment is also improved constantly.Along with BSC (base station controller) with the improving constantly of carrier frequency number, user capacity constantly increases, and causes the rapid increase of beep-page message, network MSC (mobile switching centre) side is generally still carried out paging according to the lane place for beep-page message.But the lane place is considered from aspects such as the network planning, network management, paging success rates; And impossible be provided with too small, so the increase of beep-page message all is a very serious test to the disposal ability of BSC, the bandwidth of Abis interface (being the interface between BSC and the BTS (base transceiver station)).
As shown in Figure 1, be the schematic flow sheet of BSS paging in the prior art gsm system, comprise the steps:
Step 101, BSC receives beep-page message from A mouth (being the interface between BSC and the MSC) or Gb mouth (being the interface between BSS and the SGSN (service GPRS (integration gprs) support node));
Step 102, BSC splits into many corresponding beep-page messages with this beep-page message according to the number of cells in the corresponding paging territory of this beep-page message and sends to the sub-district among the corresponding BTS;
After step 103, each sub-district are received corresponding beep-page message, finally generate the beep-page message of Um mouth (being the interface between BSS and the MS (travelling carriage)), paging MS.
In 3GPP (3rd Generation Partnership Project, third generation partner program) 48058 agreements, the structure of Paging Command (paging command) message of sending at Abis interface is as shown in table 1 below:
| Information unit | Bibliography | There is type | Form | Byte length |

The structural table of the Paging Command message of table 1 Abis interface
The Channel number (channel number) of table 1 and Paging Group (paging group) information unit, all the cell channel configuration with concrete is relevant with the paging parameters configuration, and each cell configuration is different, and final these two information units that form are also different.Because these two unit decision beep-page messages send to the sub-district, network capacity improve constantly now, three sub-districts of common configuration even six sub-districts much more more under the same website.Like this, a beep-page message just need split into three perhaps beep-page messages of more when mailing to a website, and BSC handles and concentrates, and the Abis bandwidth that causes simultaneously taking is multiplied, and has a strong impact on the transmission of normal message related to calls during insufficient bandwidth.
Summary of the invention
The present invention provides the method for base station subsystem paging in a kind of global system for mobile communications, and too big to solve the paging message data amount, the BSC that causes handles the problem of concentrating with the Abis insufficient bandwidth.
In order to solve the problems of the technologies described above, the present invention provides the method for base station subsystem paging in a kind of global system for mobile communications, comprises the steps:
(1) after base station controller BSC is received the beep-page message of A mouth or Gb mouth, organize a centralized beep-page message to send to each base transceiver station BTS website;
(2) after said BTS website is received said centralized beep-page message,, be distributed to each sub-district, and finally generate the beep-page message of Um mouth, mobile paging station MS according to the cell information of this BTS configuration or the cell list in this centralized beep-page message.
The method of the invention; Wherein, in the step (1), after said BSC receives the beep-page message of A mouth or Gb mouth; Give the paging process module; This paging process module is searched the BTS website that database finds all to send according to the paging territory in the beep-page message of receiving, organizes a centralized beep-page message to send to said each BTS website then.
Further, said centralized beep-page message sends to each BTS website through the ultra channel of Link Access Procedure LAPD on the D channel of operation maintenance cell OAM channel or said BTS support.
The method of the invention; Wherein, in the step (2), after said BTS website is received said centralized beep-page message; According to the cell information of this BTS configuration or the cell list in this centralized beep-page message; Be distributed to the broadcasting control signal road BCCH carrier frequency of each sub-district, the service processing software on the said BCCH carrier frequency generates the beep-page message of Um mouth, mobile paging station MS.
The method of the invention, wherein, said centralized beep-page message sends decision to each sub-district channel number information unit and paging group information unit remove, and increase international mobile subscriber identifier information unit.
The present invention compared with prior art with the paging process bottleneck of alleviating BSC, and saves the Abis interface communication bandwidth greatly.
Description of drawings
Fig. 1 is the schematic flow sheet of BSS paging in the prior art gsm system;
