Description

System and method for realizing single-machine multi-number service

The invention relates to the field of wireless communication and is applied to a mobile communication network. The present invention implements a method and system provided by an operator to implement a single-machine multi-number service for mobile users. Background technique

In the current environment of highly developed mobile communications and highly developed traffic, more and more business people need to conduct business across borders and need to travel frequently, and mobile phones are the most common contact method, often bringing customers and themselves. High-end long-distance, roaming call charges, or may be because the customer does not have international long distance or domestic long-distance call rights, thus affecting business development. This problem can be solved by applying a local mobile number in each service area as a local contact number.

In order to solve the above problem, the Chinese Patent Application CN200310112464 discloses a method for realizing a multi-number of machines. The invention is a multi-number service of a machine realized by using a SIM card burning number, and requires user to actively switch when using, but cannot realize simultaneous connection of all users. through.

Similarly, the Chinese patent application (CN03137321) also proposed a method, but the invention only solves the routing problem of the number of users in a single machine. The invention cannot realize transparent transmission and number display of the user registration number, and is inconvenient for reconciliation and settlement. The invention is implemented by using a primary number and a plurality of virtual numbers. When the called route is routed, it needs to be transformed to the primary number of the user for processing, that is, the conversion of the primary number and the virtual number is required.

In addition, the Chinese patent application (CN02148907) also proposes a method for implementing a number connection, but it also cannot realize the function that multiple numbers can be connected at the same time, and the user needs to manually switch to realize the number switching function. The invention is similar to CN200310112464 and the implementation mechanism is slightly different.

In summary, in addition to the above-mentioned published prior patent application, other ways in which multiple mobile numbers can be connected at the same time include: 1. Buying multiple mobile phones, one machine and one number; 2. Only one mobile phone, one machine On the 1st, forward other numbers to this number. Buying multiple mobile phones is not convenient for users. In the current mobile communication network, there are also mobile terminals that implement a multi-number service, and the mobile phone is implemented by inserting multiple SIM (Subscriber Identity Module) cards. Its lack The point is that the terminal can only use a single number at a certain time; the number is limited, depending on the number of SIM cards, currently supports up to two numbers; switching SIM operations is complicated, and requires terminal support. On the one hand, the forward transfer method has more cycles of forward setting, and the connection time will be longer, which will waste system resources. On the other hand, the call charge of the forward transfer mode will be relatively high, including long-distance charges and long-distance charges.

To open a single-number multi-number service, only one mobile phone is used, but multiple mobile numbers are bundled on the mobile phone at the same time. Each mobile number can be connected to the mobile phone at any time, and the user preferentially uses the local mobile number to make a call. , save on call costs. Single-number multi-number service is attractive to users who travel frequently, but the first thing that needs to be solved is the call charge problem, and the number is connected at the same time. The current solution does not meet the demand on either of these issues. Invention disclosure

Figure 1 illustrates the system structure in the present invention. as the picture shows:

In the system structure described in the present invention, the network is divided into a plurality of service areas, a SHLR (Standalone Home Location Register) 101 and a GMSC (Gateway Mobile Switching Center) 102. Each service area has its own independent MSC (Mobile Switching Center) 104 responsible for the switching function of the service area. The HLR (Home Location Register) 103 is responsible for user data management of the service area. The GMSC is responsible for connecting network element devices of other networks, such as LS (Fixed End Office) 105. SHLR manages user data for a single multi-number service.

The MSC/GMSC is connected to the HLR and SHLR by nickname signaling. GMSC and LS, MSG and GMSC use circuit connection for voice exchange.

When the user registers in the service area, if the user registers the single-number service, the MSC where the user is located initiates registration with the SHLR. If the user does not register the single-number multi-number service, the MSC where the user is located initiates registration with the HLR to which the user belongs.

When a user registers a single multi-number service, when the caller is called, if the caller is also a mobile user, the MSC where the caller is located initiates a location request to the SHLR. If the calling party is a fixed subscriber, the GMSC accessed by the fixed network initiates a location request to the SHLR. Fig. 2 depicts the judgment processing flow of the SHLR in the present invention. As shown in the figure, the following steps are included:

Step S201: The SHLR receives the registration request of the MSC, indicating that the user registers the single-number multi-number service;

Step S202: Find a user data table according to the user's MIN/IMSI, obtain the user data, and record information about the MSC where the user is currently located;

Step S203: Match the information of the recorded MSC with the MSC information registered in the user data, and determine whether the MSC is registered.

Step S204, if no matching record is found, indicating that the current MSC is not registered, the default MDN (mobile directory number) of the user is returned, and the processing of the user is equivalent to the un-opening of the multi-number service. Happening;

Step S205, if a matching record is found, returning a corresponding MDN;

Step S206, the information of the MSC is saved in the user data, so that when the user makes a call, the location information of the user is searched, and the registration response message is returned to the MSC, where the MDN of the user is included;

Step S207: The SHLR receives a location request message of the MSC/GMSC.

Step S208: Find a user data table according to the MDN number, locate the user data, and obtain the user location information saved in the user data, and the subsequent processing is the same as the normal processing process of the HLR.

Figure 3 depicts the process by which a user registers with a registered business area. As shown in the figure, in conjunction with FIG. 2 and FIG. 3, the user registration process referred to in the present invention is as follows:

Step S301, the MSC receives a location update request initiated by the user, determines that the user belongs to the SHLR, and sends a registration request message to the SHLR. The message includes the user's MIN/IMSI (Mobile Identity Number/International Mobile Station Identifier) and the information of the MSC. Step S302, after receiving the registration request message, the SHLR searches the user data table according to the user's MIN/IMSI to obtain the user data. The MSC information is used to match in the user data. If the record is matched, the MDN in the record is returned. If the record is not matched, the default MDN in the user data is returned. The saved MSC information is used as the location information of the user in the user data of the user. Step S303, the SHLR sends the returned MDN to the MSC in the registration response message. Figure 4 depicts the call connection process for the subscriber of the network to call the registered subscriber. As shown in the figure, in conjunction with FIG. 2 and FIG. 4, the call connection process of the user of the local network referred to by the present invention to call the registered user is as follows:

Step S401: The user of the local network initiates a call to the registered user, and the calling MSC sends a location request message to the SHLR to which the called user belongs. The called number contained in the message can be any MDN registered by the called user.

Step S402: After receiving the location request of the MSC, the SHLR may be any MDN registered by the user, and look up the user data table according to the MDN to obtain the called user data. The user's location information is saved in the user data. The SHLR replaces the called MDN with the MDN that the user is registered with at the current MSC.

Step S403: The SHLR sends a routing request to the MSC currently registered by the user according to the location information of the user. At this time, if the called subscriber number needs to be included in the routing request message, the MDN registered by the user under the currently registered MSC is used.

Step S404, the MSC currently registered by the user allocates a TLDN (Temporary Local) to the user.

The Directory Number, the user's temporary local phone number), is sent to the SHLR via a route request response message.

Step S405, the SHLR sends the TLDN to the calling MSC in the location request response message.

Step S406, the calling MSC initiates an initial address message to the called MSC according to the TLDN.

Step S407, after the MSC registered by the called party responds, the call is established.

Figure 5 depicts the call connection process for other network users to call the registered user. As shown in the figure, with reference to FIG. 2 and FIG. 5, the call connection process of the other network user referred to by the present invention to call the registered user is as follows:

Step S501: The other network user initiates a call to the registered user, and the LS where the other network user is located first routes the initial address message to the GMSC.

Step S502, the user of the local network initiates a call to the registered user, and the calling GMSC sends a location request message to the SHLR to which the called user belongs. The called number contained in the message can be any MDN registered by the called user. Step S503: After receiving the location request of the GMSC, the SHLR may be any MDN registered by the user, and look up the user data table according to the MDN to obtain the called user data. The user's location information is saved in the user data. The SHLR replaces the called MDN with the MDN that the user is registered with at the current MSC.

Step S504: The SHLR initiates a routing request to the MSC currently registered by the user according to the location information of the user. At this time, if the called subscriber number needs to be included in the routing request message, the MDN registered by the user under the currently registered MSC is used.

Step S505: The MSC currently registered by the user allocates a TLDN to the user, and sends the response to the SHLR through a route request response message.

Step S506, the SHLR sends the TLDN to the calling party in the location request response message.

GMSC.

Step S507, the calling GMSC initiates an initial address message to the called MSC according to the TLDN.

Step S508, after the MSC registered by the called party responds, the call is established.

The invention may, of course, be embodied in various other embodiments and various modifications and changes can be made in accordance with the present invention without departing from the spirit and scope of the invention. Corresponding changes and modifications are intended to be included within the scope of the appended claims. Industrial applicability
