Abstract

A mobile access hunting service processing method is provided. The method involves that: an originating mobile switching center sends a location request message of a pilot number to a home location register after receiving a call request of the pilot number; the home location register receives the location request message and determines whether current member subscriber number which needs to be connected is an intelligent subscriber number，if it is, then the current member subscriber number which needs to be connected is returned to the originating mobile switching center; the originating mobile switching center connects the member subscriber corresponding to the current member subscriber number returned by the home location register, which needs to be connected. The present invention extends the meaning of a terminal access type parameter or reserved fields of other parameters in the location request message, to prompt the home location register that the current request is a location request to member subscriber instead of a location request to the pilot number, thus solves the problem of recursive call.

Description

Method for processing mobile station to access hunt line service

The present invention relates to a mobile communication system, and more particularly to a process in which a mobile station accesses a hunt service when a mobile station accesses a hunt service pilot number and its member user (the member user is a smart subscriber) has the same number in the CDMA2000 system defined by the 3GPP2 organization. method. Background technique

The mobile station accessing the line-hopping service (MAH: Mobile Access Hunting) means that the user uses a certain number as the pilot number and binds a group of numbers. When other users dial the pilot number, they connect in a fixed order. When a user cannot connect or does not answer, the user is abandoned and the next user of the group number is continued until a user answers or all connections fail.

The 41D protocol provides support for the business. According to this protocol, the processing method of the business is as shown in Figure 1, including the steps;

i. The mobile switching center (MSC: Mobile Switch Center) sends a location request message to the home location register (HLR: Home Location Register) after receiving the call request from the calling user to the pilot number;

Ii. The HLR determines that the number has signed the MAH service, that is, obtains its first member user A, and then the HLR sends a routing request message to the serving MSC where the member user A is located by using the VLR (Visitor Location Register);

Iii. If the member user A is in an idle state, the serving MSC of the member user A returns the temporary local subscriber number (TLDN: Temporary Local Directory Number) 1 of the member user A through the route request response message. After obtaining the TLDN1 of the user A, the HLR returns the subscription information of the TLDN1 and the pilot number to the calling MSC through the location request response message. Busy, the HLR gets the next member user B of the pilot number, and then starts to pass the VLR to the member. The service MSC where the user B is located sends a route request message, and the member user B is idle or busy to process the same member user A until the member user in the idle state is connected, and if all the member users are busy, the user is directly removed. Hunting for a call, ending the hunt service. The subsequent process is described by taking the case where the member user A is in an idle state as an example.

Iv. The calling MSC connects the member user A according to the TLDN1. If the connection succeeds, the calling user establishes a call between the calling user and the member user A, and the call is disconnected after the call ends; if the connection fails, the redirected number request message is sent to the HLR to obtain the next message. Member User B's TLDN2. The calling MSC connects the member B according to the TLDN2, and if the connection succeeds, the call between the calling user and the member user B is established, and the hunt call is cancelled after the call ends, and the hunt service is terminated; if the connection fails, the redirected number is sent to the HLR. Request message to get TLDN3 of the next member user C.

The success or failure of the connection of the member user C is the same as that of the member user A and the member user B. If all the member users cannot connect, the hunt call is removed, and the hunt service is terminated. The process is as shown in Figure 1. This figure is used to establish the connection success of the MAH member user A and the success of the MAH member user B.

However, the processing method of the MAH service provided by the above 41D protocol is applicable only to ordinary users, and is not applicable to smart users. When a member user contains a smart user, the processing method of the MAH service is different. As shown in Figure 2, the member group of the MAH service includes two members: fixed number 2 (fixed telephone user), mobile number 1 ( For example, smart users include:

201-202, the calling MSC receives the call request of the calling user to the pilot number, and sends a location request message of the guiding number to the HLR;

203-205, the HLR returns a location request response message to the calling MSC, where the first member user number in the MAH service group is carried (ie, the fixed number 2); the calling MSC performs the connection according to the member user number, due to some kind of The reason for the connection failed;

206-207, the originating MSC sends a redirected number request message to the HLR, and the HLR sends the second member user number (ie, the mobile number 1) in the MAH service member group to the calling MSC through the redirected number request response message; 208 210. The calling MSC sends a location request message of the smart subscriber number to the HLR. If the HLR determines that the user is a smart user, the HLR instructs the calling MSC to trigger the intelligent process of the user and continue the connection of the user.

In the above method, when the pilot number is the real number and is the same as the number of one member user of the MAH group (the user is the smart user), the problem of the cyclic call occurs during the implementation of the MAH service (take FIG. 2 as an example). The pilot number is the same as the mobile number 1): In the above steps 208-210, when the HLR receives the location request message sent by the originating call, since the smart subscriber number carried in the message is the same as the pilot number, the HLR will The location request message erroneously considers the location request message in steps 201-202, and then returns the location request response message carrying the first member user number to the calling MSC again, thus forming a cyclic call, which cannot achieve the purpose of sequential connection. The situation is shown in Figure 3. Summary of the invention

The technical problem to be solved by the present invention is to provide a method for processing a MAH service, which avoids the problem of a recurring call in the case where the pilot number is the same as the member user number and the member user is a smart user, and the connection is smoothly implemented.

In order to solve the above technical problems, the present invention uses the following solutions:

A method for processing a mobile station to access a hunt service, the method comprising:

(1) a location request message that the originating mobile switching center sends a pilot number to the home location register after receiving the call request for the pilot number;

(2) the home location register receives the location request message, determines whether the currently required member user number is a smart subscriber number, and if so, returns the member user number to the originating mobile switching center, and proceeds to the next step;

(3) The calling mobile switching center connects the member user corresponding to the member user number returned by the home location register, and carries the prompt information and the trigger type in the location request message of the member user number sent to the home location register in the connection process. Information to indicate that the home location register is currently a location request for a member user rather than a location request for a pilot number; Thus, a recurring call in the case where the pilot number is the same as the member user number and the member user is a smart user is avoided.

In the above method, in the step (2), if the home location register determines that the member user number to be connected is not the smart subscriber number, the routing request information of the member user is directly obtained, and the information is returned to the calling mobile exchange. The center, based on this information, continues this process.

The above methods also include:

If the originating mobile switching center fails to connect to the current member user, sending a location request message of the next member user number to the home location register;

Steps (2) and (3) are repeated such that the originating mobile switching center sequentially connects to other member users of the pilot number until one member user succeeds or all member users fail to connect.

In the above method, the step (3) includes:

A. The originating mobile switching center sends the location request information of the member user number that needs to be connected to the home location register, where the prompt information and the trigger type information are carried, and the content of the trigger type information is the first time the called party accesses;

B. The home location register returns a location request response message carrying the trigger information to the originating mobile switching center;

C. The originating mobile switching center triggers the intelligent process of the member user that needs to be connected to the service control point according to the trigger information, and determines whether to continue the connection of the member user according to the indication of the service control point, and if yes, proceed to step D; Otherwise, end this connection;

D. The originating mobile switching center sends a location request message to the home location register that needs to be connected to the member user number, where the prompt information and the trigger type information are carried, and the content of the trigger type information is triggered by the called route;

E. The home location register obtains the routing information of the member user that needs to be connected, and returns the call information to the calling mobile switching center. The calling mobile switching center connects the member user according to the routing information.

In the above method, the originating mobile switching center carries the prompt information by using a terminal access type parameter field of the location request message. In the above method, the content of the prompt information is that the mobile station accesses the hunt service member to access. The invention has the following beneficial effects:

The invention extends the meaning of the reserved field (terminal access type parameter) in the location request message (that is, expands to the prompt information), so that the current member user number (the member user is a smart user) that needs to be connected is the same as the pilot number, and the HLR The location request message of the pilot number and the location request message of the member user number are not confused, and the sequential connection process can be smoothly implemented, and the problem of the cyclic call does not occur.

Preferred embodiment of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

The core idea of the present invention is: the meaning of the terminal access type parameter or other parameter retention field in the extended location request message, so that when the member user number that needs to be connected currently (the member user is a smart user) and the pilot number are the same, the prompt is carried. Information to indicate that the HLR is currently requesting location requests for member users rather than location requests for pilot numbers.

In this embodiment, the member group of the MAH service includes two members: a fixed number 2 (fixed telephone subscriber), a mobile number 1 (a prepaid subscriber under the HLR), and a pilot number and a mobile number 1 of the MAH service. the same.

Please refer to FIG. 4, which shows the processing method of the MAH service process when the called party is in the office, including The following steps:

401. The calling MSC receives a call request of the calling user to the pilot number.

402-405, the originating MSC sends a location request message of the pilot number to the HLR;

The first number of the MAH group is a fixed number, so the HLR returns a location request response message carrying the fixed number 2 to the calling MSC after receiving the location request message; the calling MSC then performs the connection according to the number in the location request response message. . In this example, the user who fails to connect to the fixed number 2 for some reason or the fixed number 2 does not answer;

406-407, after the originating MSC sends a connection failure or the fixed user does not answer, sends a redirected number request message to the HLR, and the HLR returns a redirected number request response message, where the next user number of the MAH group is carried (ie, the mobile number 1 ) ;

408. The calling MSC sends a location request message of the mobile number 1 to the HLR, and the message carries the terminal access type information (ie, the MAH member access type) and the trigger type information (the called first access type);

409. When the HLR receives the location request message, although the mobile number 1 carried in the same is the same as the pilot number, the HLR can determine that the mobile number 1 is the MAH member user number according to the terminal access type information carried in the message, and thus does not trigger. The service related to the MAH pilot number is only queried for the service of the member user. If the member user is a smart user and the trigger type is the first time, the caller is returned with the trigger information (ie, the trigger address list). a location request response message; 410 411. The calling MSC assembles a trigger of the smart user according to the trigger information in the location request response message, and triggers the intelligent process of the user to the corresponding service control point (SCP: Service Control Point); The MSC determines whether to continue the connection of the member user according to the instruction of the SCP, and if so, proceeds to the subsequent steps. In this example, the connection of the member user can be continued as an example;

412. The calling MSC sends a location request message of the mobile number 1 to the HLR, where the terminal access type information (ie, the MAH member access type) and the trigger type information (ie, the called route trigger) are triggered to trigger the called route trigger. Device

413-415, after the HLR receives, although the mobile number 1 is the same as the pilot number, but currently The access type is the access of the MAH member, so the related service of the pilot number is not triggered, and only the service of the mobile user is queried. When the mobile user is found to be a smart user and the trigger type is triggered by the called route, the MSC is terminated. That is, the intelligent user's service MSC sends a routing request message; the terminating MSC allocates the roaming number 1 and sends it to the HLR through the routing request response message, and the HLR sends the roaming number 1 to the calling MSC through the location request response message;

416 417, the calling MSC sends the analysis information to the SCP, and the SCP performs corresponding processing;

418. The calling MSC performs connection according to the roaming number 1.

At this point, the sequential connection of fixed number 2 (ordinary user) and mobile number 1 (smart user) can be achieved.

Please refer to Figure 5, which shows the processing method of the MAH service when the called party is in the local office, including the following steps:

501. The calling MSC receives a call request of the calling user to the pilot number.

502-505, the originating MSC sends a location request message of the pilot number to the HLR;

506-507, after the originating MSC sends a connection failure or the fixed user does not answer, sends a redirected number request message to the HLR, and the HLR returns a redirected number request response message, where the next user number of the MAH group is carried (ie, the mobile number 1 ) ;

508. The calling MSC sends a location request message of the mobile number 1 to the HLR, and the message carries the terminal access type information (ie, the MAH member access type) and the trigger type information (the called first access type);

509. When the HLR receives the location request message, although the mobile number 1 carried in the same is the same as the pilot number, the HLR can determine that the mobile number 1 is the MAH member user number according to the terminal access type information carried in the message, and thus does not trigger. MAH pilot number related business, only query the formation If the member user is a smart user and the trigger type is the first time that the called party accesses, the location request response message carrying the trigger information (ie, the trigger address list) is returned to the calling MSC; 510 511 The calling MSC assembles the trigger of the smart user according to the trigger information in the location request response message, triggering the intelligent process of the user to the responding service control point (SCP: Service Control Point); the calling MSC determines whether to continue the member according to the instruction of the SCP. User's connection, if yes, continue with the next steps. In this example, the connection of the member user can be continued as an example;

512. The calling MSC sends a location request message of the mobile number 1 to the HLR, where the terminal access type information (ie, the MAH member access type) and the trigger type information (ie, the called route trigger) are triggered to trigger the triggered route trigger. Device

513. After the HLR receives the mobile number 1 and the pilot number, the current access type is the MAH member access, so the related service of the pilot number is not triggered, and only the service of the mobile user is queried. If the smart user is triggered by the called route, and the station where the mobile user is located is the same MSC as the originating location request message, the location request response message is used to notify the calling MSC that the called user is in the local office;

514 515, the calling MSC sends the analysis information to the SCP, and the SCP performs corresponding processing;

516. The calling MSC pages the mobile number 1 and completes the connection.

The above embodiments are only intended to illustrate the technical solutions of the present invention and are not to be construed as limiting the invention. It should be understood by those skilled in the art that the present invention may be modified or equivalently substituted without departing from the spirit and scope of the invention. Industrial applicability

By extending the meaning of the terminal access type parameter or other parameter retention field in the location request message, the present invention makes the member user number that needs to be connected at present (the member user is a smart user) and When the pilot numbers are the same, the prompt information is carried to prompt the home location register that the current request is a location request for the member user instead of the location request for the pilot number, thereby solving the problem of the cyclic call.
