BEST MODE FOR CARRYING OUT THE INVENTION

The embodiment of the present invention is further described based on an embodiment of a method for implementing a multi-number service.

The present invention is applicable to any wireless communication network including, but not limited to, a CDMA (Code Division Multiple Access) mobile communication system.

The general specific technical solutions of the embodiments of the present invention are as follows:

1. The number management center is responsible for the allocation of multiple MDN (Mobile Directory Number) numbers (HomeMDN: MDN number assigned by the user at the home; LocalMDN: MDN number assigned by the user in the roaming place), which is at HomeHLR. (user attribution location register) and LocalHLR (user roaming location register) respectively write one machine multi-number related information;

Among them, the information related to one machine and multiple numbers is:

(1) HomeHLR is the HLR of the user's attribution, and there can be only one;

(2) The LocalHLR is a HLR for the user to roam, and there may be multiple. The following is only an example.

(3) The HomeHLR must maintain the correspondence between HomeMDN and LocalMDN and the area number of the user's roaming area.

(4) The LocalHLR must store the correspondence between LocalMDN and HomeMDN. 2. When the user of the mobile terminal registers, the user is in the MSC (Mobile Switching Center; ^GMSC) (Gateway Mobile Switching Center, Gateway Mobile Switching Center) routes the registration request message to the HomeHLR according to the user's MIN (Mobile Identification Number), and the registration request message carries the location area number;

3. The HomeHLR obtains the corresponding MDN (HomeMDN or LocalMDN) according to the area number information carried in the user registration, and returns it to the MSC where the user is located;

4. The MSC where the user is located receives the registration response message returned by the HomeHLR, and the MDN included therein is the local mobile number.

5. When the user is calling in the local area, the system processes according to the local user; the mobile switching center currently in use by the user processes the call connection according to the personal user number corresponding to the local area number information;

When the user makes a call, it is divided into the following two cases:

(1) dialing the HomeMDN of the user, and the MSC accessed by the calling party directly routes the location request message to the HomeHLR according to the called dialing;

(2) Dialing the LocalMDN of the user, the MSC accessed by the calling party first routes the location request message to the LocalHLR according to the called dialing, and the LocalHLR according to the routing request message

LocalMDN matches its saved number control relationship, returns the corresponding HomeMDN to the MSC that the calling party accesses, and then the MSC resends the location request message to the HomeHLR according to the HomeMDN;

6. The HomeHLR sends a route request message to the MSC where the user is currently located according to the user location information saved in the location request message;

7. The MSC where the user is currently located assigns the TLDN (Temporary Roaming Number) to the user, and returns the TLDN to the HomeHLR;

8. The HomeHLR returns the TLDN to the MSC that the calling party accesses;

9. The MSC that the calling party accesses is routed to the MSC where the user is located according to the TLDN, and the call is connected.

Referring to Figure 1, the system structure of the embodiment of the present invention is as follows:

In the system structure described in the present invention, the network is divided into attribution areas 11 (attributed only One) and roaming ground 12 (multiple roaming locations can exist). HomeHLR13 is responsible for user data management at the home location, and saves the correspondence between the user HomeMDN (examples 13302532688), LocalMDN (example 13302132689 below), and roaming area numbers. LocalHLRH is responsible for user data management of the roaming place, and saves the correspondence between HomeMDN: 13302532688 and LocalMDN: 13302132689. The home location 11 and the roaming area 12 have separate MSCs 16 responsible for the switching function of the service area. The number management center 15 is responsible for the allocation management of the number of the plurality of machines.

As shown in FIG. 2, the management process of the multi-number of the embodiment of the present invention is as follows: Step 201: The number management center sends a number management request message to the HomeHLR, where the message carries the user's MIN, HomeMDN: 1330253268, LocalMDN: 13302132689, and The area number of the roaming place;

Step 202: The HomeHLR saves the foregoing information carried in the number management request, and sends a number management response to the number management center.

Step 203: The number management center sends a number management request message to the LocalHLR, where the user carries the MIN, HomeMDN: 13302532688, LocalMDN: 13302132689;

Step 204: The LocalHLR saves the foregoing information carried in the number management request, and sends a number management response to the number management center.

As shown in FIG. 3, the user registration process in the embodiment of the present invention is as follows:

Step 301: When the user of the mobile terminal registers, the MSC where the user is located receives the location update request initiated by the user, determines that the user belongs to the HomeHLR, and sends a registration request message to the HomeHLR. The message includes the user's MIN and the local area number information. Step 302: After receiving the registration request message, the HomeHL searches the user data table according to the user's MIN to obtain the user data, and uses the area number information to locate the user in the machine number. The information is matched, and the corresponding MDN (or HomeMDN: 13302532688 if it is home, or the corresponding LocalMDN: 13302132689 if it is roaming) is returned to the MSC; and the MSC information is saved in the user data of the user as the User's location information. Step 303: The HomeHLR sends a registration response message to the MSC, where the message carries the MDN corresponding to the registration area (refer to step 202 for the correspondence between the specific area and the MDN).

As shown in FIG. 4, the user HomeMDN in the embodiment of the present invention performs the called process as follows:

Step 401: The user HomeMDN: 13302532688 is called, and the calling MSC sends a location request message to the HomeHLR to which the called user belongs, and the called number included in the message is HomeMDN: 13302532688;

Step 402: After receiving the location request message of the calling MSC, the HomeHLR searches for the location information of the user according to HomeMDN: 13302532688, and sends a routing request message to the MSC currently registered by the user, and the called number included in the message is HomeMDN: 13302532688;

Step 403: The MSC currently registered by the user allocates a TLDN to the user, and sends the TLDN to the HomeHLR through a route response message.

Step 404: The HomeHLR sends the TLDN to the calling MSC in the location response message.

As shown in FIG. 5, the user LocalMDN in the embodiment of the present invention performs the called process as follows:

Step 501: The user LocalMDN: 13302132689 is called, and the calling MSC sends a location request message to the LocalHLR where the called user is located, and the called number included in the message is LocalMDN: 13302132689;

Step 502: After receiving the location request message of the calling MSC, the local HL searches for the multi-number information of the user according to LocalMDN: 13302132689, and matches the corresponding HomeMDN: 13302532688;

Step 503: The LocalHLR returns a location response message to the calling MSC. The called number contained in the message is HomeMDN: 13302532688, which does not contain location information. The location response message returned by the LocalHLR needs to be marked. It can instruct the MSC to return only the HomeMDN: 13302532688 number. The MSC needs to continue to HomeHLR according to HomeMDN: 13302532688. Sending a location information request message; Step 504: The calling MSC sends a location request message to the HomeHLR according to HomeMDN: 13302532688 returned in the LocalHLR location response message, and the called number included in the message is HomeMDN: 13302532688;

Step 505, the process is the same as step 402;

Step 506, the process is the same as step 403;

Step 507, the process is the same as step 404. Industrial applicability

The invention opens a multi-number service, that is, only one mobile phone is used, but a plurality of mobile numbers are bundled on the mobile phone at the same time, and each mobile number can be associated with a corresponding roaming place, and each mobile number can be at any time. After connecting to the mobile phone, the user preferentially uses the local mobile number to make a call, thereby saving the call cost. The management of a single mobile phone corresponding to multiple mobile numbers is automatically implemented by the system, and there is no special requirement for the mobile terminal, which does not increase any expenditure of the user, and at the same time effectively reduces the cost of the off-site call. Therefore, a multi-number service is still very attractive to users who travel frequently.
