Description

A Realization Method of Virtual MSC/VLR

technical field

The invention relates to the communication field, in particular to a method in which a real MSC/VLR (Mobile Switching Center/Visitor Location Register) is used as multiple virtual MSCs/VLRs in cellular mobile communication.

Background technique

MSC/VLR is one of the core network elements of the cellular mobile communication system. It is a functional entity that controls all mobile stations in its coverage area and completes services.

Operators provide users with services through MSC/VLR and calculate fees according to certain rules. For voice services, most mobile operators bill users based on the following information:

1) Calculation of service costs: 1) billing user number; 2) the area where the billing user is located; 3) the number of the peer user; 4) the area where the peer user is located. The definition of the billing user in the present invention: in the calling bill, the billing user refers to the calling user; in the called bill, the billing user refers to the called user; in the call forwarding bill, the billing user Refers to the user who has forwarded the service.

Each MSC/VLR has a unique MSCnumber (MSC number), VLRnumber (VLR number), and MSRN (mobile subscriber roaming number) prefix. Operators can use MSCnumber or VLRnumber or MSRN prefix to identify the area where the mobile subscriber is located.

In most cases, one MSC/VLR covers one area, so the operator can correctly calculate the business expenses incurred by mobile users according to the MSCnumber or VLRnumber or MSRN prefix.

In a few cases, one MSC/VLR covers multiple regions, but the MSCnumber or VLRnumber or MSRN prefix corresponding to the MSC/VLR only identifies one region, resulting in billing-related equipment (MSC/GMSC, SCP, billing center) The actual region of the user is not known. Therefore, billing cannot be performed correctly.

In order to realize that one MSC/VLR covers multiple regions and charges correctly, it is necessary to solve the defect that "one MSC/VLR can only identify one region".

Contents of the invention

The technical problem to be solved by this invention is to provide a kind of method that divides a "real MSC/VLR" into a plurality of "virtual MSC/VLR", thereby overcoming the problem of a "real MSC/VLR" in existing GSM, CDMA and other cellular mobile communication systems. VLR" can only identify defects in one area.

In order to achieve the above object, the present invention provides a kind of method of virtual MSC/VLR, comprises the steps:

Step 1. On the "real MSC/VLR", assign a "virtual MSC/VLR" to each region;

This step 1 may also include the following steps:

Step 11. Classify all the cells in an area covered by the "real MSC/VLR" into a cell group. Establish correspondence between regions and community groups;

Step 12, distribute a "virtual MSC/VLR" for each region;

Step 13, distribute MSCnumber, VLRnumber, MSRN prefix for each "virtual MSC/VLR";

Step 2, when "real MSC/VLR" handles mobile station services, obtain corresponding MSCnumber or VLRnumber or MSRN prefix according to the GCI (Global Cell Identifier) where mobile station is located;

This step may also include the following steps:

Step 21, when "real MSC/VLR" handles the mobile station service, if it involves the processing of MSCnumber or VLRnumber or MSRN, enter the processing of step 2-2, otherwise end the processing;

Step 22, "real MSC/VLR" obtains the corresponding area according to the GCI where the mobile station is located;

Step 23, obtain the corresponding "virtual MSC/VLR" according to the region;

Step 24, obtain corresponding MSCnumber or VLRnumber or MSRN prefix according to "virtual MSC/VLR";

Step 25, "real MSC/VLR" uses the acquired MSCnumber or VLRnumber or MSRN prefix to process the mobile station service;

Step 3. Correctly calculate the service fee incurred by the mobile user according to the MSCnumber or VLRnumber or MSRN prefix.

The MSCnumber or VLRnumber or MSRN prefix corresponds to a mobile subscriber one by one.

The beneficial effects of the present invention are: adopting the technical scheme of the present invention, compared with the prior art, the use of "virtual MSC/VLR" can conveniently realize the function that one MSC/VLR covers multiple areas and charges correctly, and greatly saves equipment cost.

Detailed ways

The "virtual MSC/VLR" provided by the present invention is to meet the correct billing requirements related to regions when one MSC/VLR covers multiple regions, and the concept of "virtual MSC/VLR" is proposed. Among them, the physical configuration and resource management of "real MSC/VLR" still use the original MSC/VLR platform, and the attributes related to a certain region are abstracted together and managed with "virtual MSC/VLR", "virtual MSC/VLR" MSC/VLR" is just a logical concept and does not require any new physical equipment.

Below is a kind of embodiment that realizes the present invention:

First, add the configuration table of "virtual MSC/VLR" on the "real MSC/VLR", see Table 1.

Table 1 Virtual MSC/VLR All GCIs in the region MSCnumber VLRnumber MSRN prefix

Then, see step 100, assign a "virtual MSC/VLR" to each area covered by the "real MSC/VLR". Each "virtual MSC/VLR" covers a group of cells (identified by GCI) in the area, and has its own MSCnumber, VLRnumber, and MSRN prefix. Configure the virtual MSC/VLR", cell group, MSCnumber, VLRnumber, and MSRN prefix to Table 1 to establish a corresponding relationship.

When the business of the mobile station is related to MSCnumber or VLRnumber or MSRN prefix, the "real MSC/VLR" obtains the corresponding MSCnumber or VLRnumber or MSRN prefix according to the GCI where the mobile station is located. In this way, the area where the mobile station is located can be identified through MSCnumber or VLRnumber or MSRN prefix to ensure correct charging.

Below in conjunction with accompanying drawing 1 the implementation of technical scheme is described in further detail:

Scenario for implementing the present invention: one MSC/VLR of a cellular mobile communication system covers multiple areas, and the operator needs to perform billing processing according to the area where the mobile station is located.

Implement the data configuration method of the present invention:

Step 101, assign a "virtual MSC/VLR" to each region, and a "virtual MSC/VLR" covers all cells in a region;

Step 102, assigning MSCnumber, VLRnumber, and MSRN prefix for each "virtual MSC/VLR"; a "virtual MSC/VLR" has a unique MSCnumber, a unique VLRnumber, and a unique MSRN prefix. Configure the data related to the "virtual MSC/VLR" in Table 1.

Step 103, judge whether the business of mobile station relates to MSCnumber, VLRnumber, MSRN prefix;

Step 104, obtaining the corresponding region according to the GCI where the mobile station is located;

Step 105, obtain the corresponding "virtual MSC/VLR" according to the region;

Step 106, obtain corresponding MSCnumber, VLRnumber, MSRN prefix according to "virtual MSC/VLR";

Step 107, use the acquired MSCnumber, VLRnumber and MSRN prefix to process the mobile station service.

When the mobile station has business, the function of the present invention is: the area where the mobile station user is located when the mobile station user has business can be identified through the "virtual MSC/VLR". For example: 1) If the location update occurs between the "virtual MSC/VLR" of the user, the "virtual MSC/VLR" will transmit the corresponding VLRnumber and the GCI where the user is located to the HLR. 2) If the VLR receives the roaming number request from the HLR, the "real MSC/VLR" should be able to allocate a roaming number according to the GCI where the mobile subscriber is located (this GCI corresponds to a region). The prefix of this roaming number is the "MSRN prefix" corresponding to the "virtual MSC/VLR". 3) If the "real MSC/VLR" needs to generate a charging bill, the "MSCnumber" corresponding to the "virtual MSC/VLR" can be obtained according to the GCI where the charging user is located.

Using the method of the present invention can avoid the difficulty that other network element equipment cannot identify the actual area where the mobile station is located due to one MSC/VLR covering multiple areas, thereby causing incorrect billing, and can effectively improve the performance of the MSC/VLR.

The above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without Any deviation from the spirit and scope of the technical solutions of the present invention shall be covered by the scope of the claims of the present invention.
