Abstract

The disclosed sub-LAC calling method comprises: the MSC receives and sends the calling command to BSC, and the BSC executes calling, wherein the MSC should obtain the last local sub-area BSC information of called MS. This invention controls network loading efficiently, and ensures the system security and reliability.

Description

Secondary LAC paging method

Technical field

The present invention relates to a kind of paging method, especially a kind of the following lane place coding (Location AreaCode is called for short LAC) for the method that unit carries out paging, belongs to communication technical field.

Background technology

The GSM paging, be meant mobile phone do network when called initiatively issuing message seek the signaling procedure of called mobile phone.GSM tradition paging mode is, call out travelling carriage (Mobile Station, abbreviation MS) route arrives (the Mobile Switching Centre of mobile switching centre of this MS of service, be called for short MSC) after, as shown in Figure 1, MSC is promptly to the MS issuing page message, and beep-page message is broadcasted in whole lane place (LocationArea), that is to say that all base transceiver stations (Base TransceiverStation is called for short BTS) in this lane place all will send beep-page message to MS.In this lane place just the called MS in receiving common control channels (Common Control Channel, be called for short CCCH) information just can receive this beep-page message and initiate page response.

In existing GSM paging technique, LAC is the Minimum Area that MS can pagedly arrive, and paging is that unit carries out with LAC.If a LAC has a plurality of base station controllers (Base StationController is called for short BSC), the paging amount that then this LAC carried is the summation of all BSC paging amounts, and the size of LAC and paging amount present linear relationship.

Fast development along with the mobile communication business amount, especially in great festivals or holidays, the paging amount that business burst is brought is increased sharply to BSC, Abis interface (two functional entity BSC of base station sub-system and the communication interface between the BTS) and relevant treatment unit load have caused very big pressure, also brought very big hidden danger for the safe and stable operation of network, for reducing this risk, network planning personnel have to divide the lane place more and more littler, and this has brought the problem of another one sternness, the too much overstocked signaling consumption number of times of user mobility management that causes that is the lane place significantly increases, thereby taken a large amount of Internet resources, network load safety and Internet resources become the contradiction that becomes increasingly conspicuous of pendulum in face of the planning personnel.

Summary of the invention

The objective of the invention is no longer is least unit with LAC, but is that unit carries out paging with the BSC under the sub-district, the last place of MS (recentcell), and the paging precision is provided, and saves the paging resource, reduces network load, improves the LAC bearing capacity.

For achieving the above object, the invention provides a kind of secondary LAC paging method, comprise: MSC receives paging command (paging command), MSC sends to BSC with paging command, BSC carries out paging, described MSC sends to BSC with paging command and specifically comprises: MSC obtains the BSC information of sub-district, the last place of called MS, and according to described BSC information paging command is sent to corresponding BSC.

In order to pass through Visited Location Registor (Visitor Location Register, be called for short VLR) middle cellular global identity (the Cell Global Identification that stores, abbreviation CGI) BSC at the last place of information consumer positioning, the BSC information that described MSC obtains sub-district, the last place of called MS specifically comprises:

MSC is to the CGI of VLR inquiry sub-district, the last place of called MS;

VLR returns the CGI of sub-district, the last place of called MS to MSC;

MSC searches the BSC information that obtains sub-district, the last place of called MS according to described CGI.

The present invention has created secondary LAC paging mechanism, and under this page-mode, the beep-page message only sub-district under the BSC at MS place is broadcasted.Like this, the paging amount of the paging amount of a LAC carrying and single BSC carrying is basic identical, and no longer the increase along with its scope forms doubly increase, thereby has effectively controlled network load, has saved Internet resources, has fundamentally guaranteed the safe and stable operation of network.On the other hand, for LAC, inferior LAC is the least unit of paging, and the least unit that the position is upgraded remains LAC, the restricting relation that call signaling and position are upgraded in the LAC planning is broken like this, thus the relation between balanced network load safety and the mobile management expense.

Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Fig. 3 is the part flow chart of the preferred embodiment two of a kind of secondary LAC paging method provided by the present invention.

Embodiment

Referring to Fig. 2, in the preferred embodiment one of a kind of secondary LAC paging method provided by the present invention, comprise: MSC receives paging command, obtain the BSC information of sub-district, the last place of called MS, and paging command being sent to corresponding BSC according to described BSC information, BSC carries out paging by existing method.

In actual applications, the BSC information of obtaining sub-district, the last place of called MS has multiple implementation, and those skilled in the art can be based on the present invention and described BSC information and the described secondary LAC paging method that obtains sub-district, the last place of called MS of existing techniques in realizing.

In the preferred embodiment two of a kind of secondary LAC paging method provided by the present invention, be with the different of preferred embodiment one, referring to Fig. 3, the BSC information that described MSC obtains sub-district, the last place of called MS specifically comprises: MSC is to the CGI of VLR inquiry sub-district, the last place of called MS; VLR inquires about the CGI that obtains sub-district, the last place of called MS in inside, and CGI is returned MSC; MSC searches the BSC information that obtains sub-district, the last place of called MS according to described CGI.In the practical application, store the table of comparisons of CGI and BSC information among the MSC.

Further, in actual applications, may be owing to some abnormal cause, VLR finds the inner CGI of sub-district, the last place of called MS that do not store, and this moment, VLR sent failure information to MSC, and MSC carries out paging by existing method after receiving this failure information.

In the preferred embodiment three of a kind of secondary LAC paging method provided by the present invention, be that with the different of preferred embodiment one in setting-up time, MSC receives page response, then paging this time finishes.

In the preferred embodiment four of a kind of secondary LAC paging method provided by the present invention, be with the different of preferred embodiment one, in setting-up time, MSC does not receive page response, MSC judges whether to allow heavily paging (repaging) according to the parameter configuration of self, if allow then to carry out paging by existing method, paging this time finishes if do not allow then.

It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
