Detailed Description

The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.

According to the service trigger processing mechanism of the S-CSCF, in the registration process, the S-CSCF acquires a relevant IFC set applied to a terminal user from an HSS (Home Subscriber Server). When the S-CSCF receives the request message from the Mw interface, the S-CSCF checks the filter criteria one by one according to the IFC priorities and delivers calls meeting the filter criteria to the application server specified in the criteria. The S-CSCF performs the following processing procedures:

step 1: a list of filter criteria is established for the request, the list being prioritized by the criteria. The order of the filter criteria should not change until the request leaves the S-CSCF via the Mw interface.

Step 2: analyzing the received request, and searching for an SPT (Service Point Trigger) included in the request.

And step 3: check if the trigger point in the next highest priority filter criteria matches the requested SPT, and:

a) if not, the S-CSCF shall proceed immediately to step 4.

b) If there is a match, the S-CSCF will:

i) add an ODI to the request to enable the S-CSCF to recognize the incoming side message even if the dialog identity is changed due to the application server performing third party call control.

Ii) forwarding the request over the ISC interface to the application server indicated in the current filter criteria. The application server executes the service logic and can modify the request and return it to the S-CSCF via the ISC interface.

Iii) if a request is received from the application server again through the ISC interface, proceeding to step 4.

And 4, step 4: the above processes of step 2 and step 3 are repeated for each filtering criterion initially established in step 1 until the last filtering criterion is checked.

And 5: the request is routed according to standard SIP (Session Initiation Protocol) routing behavior.

If an application server decides to terminate a request locally and returns the last response to the request to the S-CSCF via the ISC interface, the S-CSCF will abort the match check for low priority triggers in the list. The last response should contain the identifier ODI defined in step 3-b) -i) above to enable the S-CSCF to associate the message.

The ISC interface enables the S-CSCF to associate the message triggered to the platform by the ISC interface with the message returned to the S-CSCF by the platform, and triggers the service successively according to the priority order.

The one number multi-terminal nests other value added services, and the same number service flow of the attached card as the calling can be shown as the processes of 101-106 in figure 1.

As can be seen from fig. 1, the sequence is: firstly triggering the value added service of the attached card, and then triggering the one number multi-terminal service to change the number of the calling party. Because the ISC interface starts the ODI identifier, according to the processing mechanism, the subsequent calling process in the S-CSCF is always the function of the IFC set signed by the attached card, even if the calling number is changed into the main card number, the calling number can not be triggered to the main card value-added service platform under the function of the IFC set signed by the main card.

The processing mode ensures that the attached card must be signed with related value added services at the same time, and normal service functions and correct charging can be realized only by associating the attached card with the account number of the main card in the value added service platform.

The process of the co-vibration service flow of the first terminal nested with other value added services and the calling card as the called is shown as 201-210 in fig. 2.

As can be seen from fig. 2, the sequence is: the value added service of the main card is triggered first, and then the one-number multi-terminal service is triggered to carry out the called party simultaneous ringing. The main card value-added service platform has a main card as a called party and the main card forwards forwarded to an attached card 2 tickets; and then triggering to the value-added service of the attached card, wherein the value-added service platform of the attached card has the attached card as a called ticket.

The processing mode eliminates the two call tickets which are used as called cards and are forwarded to the attached cards before the main card through the association of the background account number, thereby avoiding repeated charging.

Fig. 3 is a flowchart of an embodiment of a method for connecting a first-terminal call to a plurality of terminals according to the present disclosure.

In step 301, the one-number-multi-terminal platform receives a call request from the calling side S-CSCF, where the call request includes a called number, a calling number, and an ODI.

In step 302, the platform for one number of multiple terminals executes the service logic for one number of multiple terminals for the call request, and deletes the ODI in the call request to generate an updated call request.

In one embodiment, the one-terminal multi-terminal call service logic comprises: if the calling number in the calling request is the card attaching number, modifying the calling number into a main card number associated with the card attaching number of the calling; if the called number in the calling request is the main card number, the called number is modified into an attached card number associated with the called main card number.

In step 303, the updated call request is forwarded to the I-CSCF or fed back to the source S-CSCF of the call request, so as to be forwarded to the called side S-CSCF, thereby completing call connection.

Fig. 4 is a flowchart of another embodiment of a method for connecting a multi-terminal call according to the present disclosure.

In step 401, the S-CSCF receives a call request from the card attached number, and triggers a one-number-multi-terminal service according to the IFC subscribed by the card attached number.

In step 402, the S-CSCF sends a call request to the multi-terminal platform # one. The calling number in the call request is a card attached number.

In step 403, the one-number-multiple-terminal platform modifies the calling number into a main card number associated with the attached card number of the calling, deletes the ODI in the call request, and generates an updated call request.

In step 404, the multi-terminal platform # a sends an update call request to the I-CSCF.

In step 405, the I-CSCF queries the S-CSCF to which the main card number is registered and forwards the update call request after receiving the update call request.

In one embodiment, the multi-terminal platform # a may not perform

steps

404 and 405, but send an update call request to the S-CSCF in step 402, and the S-CSCF continues to perform the next call connection according to the normal communication procedure.

In step 406, the S-CSCF to which the main card number is registered triggers the main card value added service platform according to the IFC subscribed by the main card number.

By the method, the ODI is deleted in the process of forwarding the call request by the one-number multi-terminal platform, so that the S-CSCF at the called side cannot be associated with the previous call request due to the lack of the ODI after receiving the updated call request, the S-CSCF at the called side determines the IFC according to the calling number modified into the main card number, and triggers the main card value-added service, thereby ensuring the realization of normal service function and charging without signing the same value-added service for the main card number and the attached card number, reducing the complexity of the value-added service signing, and improving the reliability of the charging.

The signaling flow chart of an embodiment of the method for connecting a multi-terminal call is shown in fig. 5.

In 501, the attached card initiates a call, and the S-CSCF where the attached card is registered triggers a one number multi-terminal service according to the IFC signed by the attached card, and sends a call request to the one number multi-terminal platform, where the call request includes a called number, a calling number (for the attached card), and an ODI.

In 502, the one-number-multi-terminal platform executes the calling party number service logic, changes the calling number from the attached card to the main card, and deletes the ODI.

In 503, the platform with one terminal sends a call request to the I-CSCF, which includes the called number, the calling number (changed to the main card), the orig identifier, and no ODI identifier.

In 504, the I-CSCF queries the S-CSCF where the main card is registered according to the calling number; the call request is forwarded to the S-CSCF.

In 505-506, the S-CSCF where the main card is registered triggers the main card value added service platform according to the IFC signed by the main card, so as to implement nesting of the one-number multi-terminal service with other value added services.

By the method, normal service function and charging can be ensured without signing the same value-added service for the main and the attached card numbers, the complexity of signing the value-added service is reduced, and the reliability of charging is improved.

Fig. 6 is a flowchart of another embodiment of a method for connecting a multi-terminal call according to the present disclosure.

In step 601, the S-CSCF receives the call request and triggers the value added service platform according to the IFC priority subscribed by the calling number.

In step 602, the S-CSCF triggers the one-number-multi-terminal service, and sends a call request to the one-number-multi-terminal platform.

In step 603, the one-number-multi-terminal platform modifies the called number into an attached card number associated with the called main card number, deletes the ODI in the call request, and generates an updated call request.

In step 604, the multi-terminal platform with one number sends an update call request to the I-CSCF.

In step 605, after receiving the update call request, the I-CSCF queries the S-CSCF to which the card attached number is registered according to the called number and forwards the update call request.

In one embodiment, the multi-terminal platform # a may not perform

steps

604 and 605, but send the update call request to the S-CSCF in step 602, and the S-CSCF continues to perform the next call connection according to the normal communication procedure.

In step 606, the S-CSCF to which the card attached number is registered continues the call to the card attached number according to the P-CSCF subscribed to the card attached number.

By the method, the ODI is deleted in the call request forwarding process of the one-number multi-terminal platform, so that the S-CSCF at the called side cannot be associated with the previous call request due to the lack of the ODI after receiving the updated call request, call tickets cannot be repeatedly generated, partial call tickets do not need to be removed through background account association, the charging complexity is reduced, and the charging reliability is improved.

A signaling flow diagram of another embodiment of the method for connecting a multi-terminal call is shown in fig. 7.

In 701-702, the main card is called, and the S-CSCF where the main card is registered triggers the value-added service platform first and then triggers the one-number multi-terminal platform according to the IFC priority signed by the main card.

In 703, the main card S-CSCF sends a call request to the one number multi-terminal platform, which includes the called number (which is the main card), the calling number, and the ODI.

In 704, the one-number multi-terminal platform executes the called co-vibration service logic, changes the called number from the main card to the attached card, and deletes the ODI.

In 705, a call request is sent to the I-CSCF containing the called number (changed to attached card), the calling number, and no ODI identifier.

In 706, the I-CSCF queries the S-CSCF where the called card is registered according to the called number, and forwards the call request to the S-CSCF.

In 707, the S-CSCF at which the card attach registration is located completes the call connection to the card attach according to the P-CSCF at which the card attach registration is located.

By the method, the call ticket can not be repeatedly generated, and partial call tickets do not need to be removed through background account association, so that the charging complexity is reduced, and the charging reliability is improved.

and the S-CSCF to which the attached card number is registered continues the call to the attached card number according to the proxy P-CSCF signed by the attached card number.

6. A multi-terminal platform, comprising:

a request receiving unit, configured to receive a call request from a calling side service S-call session control function CSCF, where the call request includes a called number, a calling number, and an original dialog identifier ODI;

the updating request unit is configured to execute a one-number-terminal multi-terminal calling service logic on the calling request by the one-number-terminal multi-terminal platform, delete the ODI in the calling request and generate an updating calling request;

and the request forwarding unit is configured to forward the updated call request to the query I-CSCF or feed back the updated call request to the source S-CSCF of the call request so as to forward the updated call request to the called side S-CSCF, thereby completing call connection.

7. The platform of claim 6, wherein the update request unit is configured to: and if the calling number in the calling request is an attached card number, modifying the calling number into a main card number associated with the attached card number of the calling.

8. The platform of claim 6, wherein the update request unit is configured to: if the called number in the calling request is a main card number, modifying the called number into an attached card number associated with the main card number of the called party.

9. A one number multi-terminal call connection device includes:

a memory; and

a processor coupled to the memory, the processor configured to perform the method of any of claims 1-5 based on instructions stored in the memory.

10. A computer readable storage medium having stored thereon computer program instructions which, when executed by a processor, implement the steps of the method of any one of claims 1 to 5.
