Technical field

The present invention relates to the field of intelligent network communication technologies, and in particular, to a multi-service control processor group pickup method, device, service control processor and computer storage medium.

Background technique

The service of the centralized user switch (CENTRalized EXchange, Centrex) under the Next Generation Network (NGN)/IP Multimedia Subsystem (IMS) is to connect the wired and NGN/IMS domains. The wireless access terminals together form a virtual internal communication network. Within Centrex, users can talk to each other via short numbers and implement some of the basic business functions of Centrex users, such as number display and restriction, call forwarding, call forwarding, and attendant. The intra-group users of the Centrex service may include the broadband access of the mobile terminal used in the IMS domain, the broadband access of the fixed terminal, and the terminal of the Plain Old Telephone Service (POTS) through the session initiation protocol. A gateway (Session Initiation Protocol SIP Access Gateway, abbreviated as AG) accesses or accesses the Access Gateway Control Function (AGCF), which is mainly based on the Session Initiation Protocol (SIP). The incoming soft and hard terminals and the traditional POTS terminals can be further divided into several user groups in the Centrex group.

Among them, the same group of pickup services is an important business feature in the Centrex business, and it has a wide range of applications in the traditional circuit domain. The specific group answering is as follows: When an extension has no answer, the other extensions in the same user group will respond. The operation mode is: when the unanswered extension rings, the pickup user presses the same group. Pick up the access code. When using the same group pickup function, the pickup user dials the same group pickup access code to pick up the incoming call of the extension that is ringing.

However, the existing peer-to-peer pickup technology is implemented based on a single service control processor (CP), but the amount of users carried by a single CP of the application server is limited, so when the number of users reaches a certain scale It is necessary to use multiple CPs for load balancing, thereby improving the processing power of the service system. However, the multi-CP architecture inevitably poses a huge challenge to the processing of the service, because the user is on a different CP when triggering the service. Hard to handle. As shown in FIG. 1, under the multi-CP framework, the calling user A calls the called user B, and the user B rings. However, when the CP-C responsible for user C receives the pickup request from user C, the process cannot continue. Therefore, the existing same group pickup technology cannot complete the same group pickup function under the multi-CP architecture.

While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

Embodiment 1

According to an aspect of the present invention, a multi-service control processor co-group pickup method is provided, which is applied to a pickup party CP, and the method first receives a first-generation answer request sent by a pickup user; Determining the terminal information of the user to determine whether the answering user is legal; again, if the judgment is legal, obtaining, according to the terminal information of the pickup user, the called party CP records when the called user starts ringing, And terminal information of the called user that belongs to the same group and is in a ringing state; and, again, sends a second generation request requesting the terminal information of the called user to the called party CP; Finally, a call between the pickup user and the calling user is established according to the second generation request and the terminal information of the pickup user.

The multi-service control processor in the same embodiment of the present invention collects the called user who belongs to the same group and is in the ringing state by the terminal information of the user, and establishes the pickup CP and the called party. The signaling connection between the CPs enables the same group pickup function under multiple CPs.

As shown in FIG. 2, the method includes:

Step S21: Receive a first generation answer request sent by the pickup user.

The first proxy request carries the terminal information of the pickup user. When the calling user calls the called user and the called user rings, the calling user can send a first generation answer request carrying the terminal information of the picking user to the picking party CP, so that the calling party CP can answer the answer. The terminal information of the party finds the called user who belongs to the same group and is in the ringing state with the pickup user.

Step S23: Determine, according to the terminal information of the pickup user, whether the pickup user is legal.

The terminal information of the pickup user may include the user number of the pickup user, the pickup access code, and the SDP information. Further, step S23 includes:

Therefore, the multi-service control processor of the embodiment of the present invention does not need to know the number of the called user in the process of invoking the user to initiate the pickup request, and only needs to dial the pickup access code. The accessing party CP accesses the database to find the called user who needs to be picked up in the same group as the pickup user according to the user number of the pickup user, thereby improving the user experience.

Step S25: If the judgment is legal, the called party CP is recorded in the database according to the terminal information of the pickup user, and is recorded when the called user starts ringing, and belongs to the same group and is in a ringing state. The terminal information of the called user.

In the multi-service control processor of the embodiment of the present invention, the called party CP records the terminal information of the called user in the database when the called party rings, and modifies the user status of the called user to ring. Therefore, the calling party CP can share the terminal information of the called user from the database, thereby establishing a signaling connection between the calling party CP and the called party CP, thereby implementing the same group pickup function under multiple CPs.

The method according to the terminal information of the pickup user acquires, in the database, the called party recorded by the called party CP when the called user starts ringing, and the called user belongs to the same group and is in the ringing state. Steps for terminal information, including:

The multi-service control processor in the embodiment of the present invention is applied in the same group to include multiple CPs, and each CP is responsible for the call service of multiple users, and therefore, the group may exist. In the case that multiple users are called at the same time, after determining the legal step of the answering user, the ringing start time of the plurality of called users that belong to the same group and is in the ringing state needs to be acquired in the database. Therefore, by comparing the start times of the ringing times, the called user who starts ringing at the earliest is obtained, so that the pickup user successfully picks up the called user who starts ringing at the earliest.

Step S27: Send a second proxy request carrying the terminal information of the called user to the called party CP.

Step S29: Establish a call between the pickup user and the calling user according to the second proxy request and the terminal information of the pickup user.

Further, step S29 includes:

Receiving the consent pickup message sent by the called party CP according to the second proxy request to verify that the called user is in a ringing state, and carrying a call-id between the called party CP and the called user Notification message

Obtaining SDP information of the pickup user from the first proxy request;

Sending, to the called party CP, a request access message carrying the call-id and the SDP information of the pickup user, so that the called party CP releases the called user according to the request access message The original call of the side, and forward the SDP information of the pickup user to the calling party CP;

In the process of establishing a call between the pick-up user and the calling user, the pick-up user needs to obtain the SDP information of the calling user, and the calling user needs to obtain the SDP information of the pick-up user, so that the above-mentioned can make the pick-up user and The calling user separately obtains the SDP information of the other party, thereby implementing the call between the calling user and the calling user.

The terminal information for the called user includes the long number of the called user and the user status. When the called user rings, the called party CP changes the user state to a ringing state; when the called user picks up the phone and makes a call with the calling user, the called party CP rejects the body pickup request. Certainly, the multi-service control processor of the embodiment of the present invention has the same content of the terminal information, and the specific content of the terminal information of the called user is not limited thereto.

The multi-service control processor and the group pickup method of the embodiment of the present invention are applied to a network element of a multi-CP architecture. For example, as shown in FIG. 3, the AS is a Centrex service application server, and includes modules such as CP-A, CP-B, CP-C, Proxy, and DB. Among them, CP-A, CP-B, and CP-C are CPs responsible for different user services; Proxy is a unified external interface of the CP. After receiving a call request, the calling side follows the called number according to the calling number/called side. The number is distributed to the call. Correct The specific distribution policy may be: numbers with tail numbers 0, 1, 2 are distributed to CP-A; numbers with tail numbers 3, 4, and 5 are distributed to CP-B; tail numbers are 6, 7, 8, The number 9 is distributed to the CP-C. The DB is the database of the Centrex service. When the three CP processes are processed, the service data is obtained from the database; the CSCF is the core network device; and the UE is the user terminal. The UE establishes a connection with the CP responsible for the UE through the CSCF, and implements a call or called function through each module shown in FIG.

At this time, the UE-B-504 is in a ringing state, and the CP-B will be the UE. -B terminal information is recorded in the database, and the user state of UE-B is changed to a ringing state;

Step 407, the pickup user UE-C sends a first generation answer request INVITE (SDP C) carrying its own SDP information to the CP-C responsible for the service of the UE-C;

Step 408: After receiving the INVITE (SDP C) message, the CP-C accesses the public database DB, and finds the user UE-B in the same group of the UE-C in the ringing state of the called process, and then uses the long number of the UE-B. Sending a second generation request SUBSCRIBE for the called number, wherein the core network sends the SUBSCRIBE to the CP-B according to the called number;

Step 409: After receiving the SUBSCRIBE sent by the CP-C, the CP-B returns a confirmation message 200 OK.

Step 410: The CP-B sends a notification message NOTIFY to the CP-C carrying a call-id between the called party CP and the called user, to notify the CP-C to agree to the pickup;

Step 411: After receiving the NOTIFY, the CP-C replies to the CP-B with a confirmation message 200 OK;

Step 412: The CP-C sends a SDP information carrying the UE-C and a Replaces header notification message INVITE (SDP C+ Replacement Replacement) to the CP-B, where the Replaces header includes the call-id;

Step 413: After receiving the INVITE (SDP C+Replaces), the CP-B sends a cancel request CANCEL to the UE-B according to the call-id in the Replaces header.

Steps 414-415, when UE-B confirms cancellation, reply CP-B with a confirmation message 200 OK and an end request Request Terminated, so that CP-B releases the original call on the UE-B-504 side according to the call-id in the Replaces header. ;

Step 416, when successfully released, the CP-B sends an acknowledgement identifier ACK to the UE-B;

Steps 417-418 and CP-B send the SDP information of the UE-C obtained in the above step to the CP-A, and the CP-A further forwards the message to the UE-A:

Steps 419-420, UE-A returns an acknowledgement identifier ACK to the CP-B according to the original path of the received SDP information of the UE-C;

Steps 421 to 422, after receiving the ACK, the CP-B sends the SDP information of the UE-A to the CP-C, and the CP-C forwards the SDP information of the UE-A to the UE-C.

Steps 423-424: The UE-C returns an acknowledgement identifier ACK to the CP-B according to the path of receiving the SDP information of the UE-A. At this time, the UE-A and the UE-C enter the call, and the service completes the pickup.
