The IDP message carries the call information of the call that fails to be connected, and specifically includes: information of the calling terminal of the call, information of the called terminal of the call, and a reason for the connection failure of the call.

Specifically, depending on the location where the connection fails, the switching device that sends the IDP message also has a difference:

When the connection failure is caused by the connection failure of the mobile switching center (MSC) to which the calling terminal of the call belongs, this step is specifically that the MSC to which the calling terminal that the SCP receives the call is sent after the call connection fails. IDP message. In this case, the reason for the connection failure may be that when the MSC to which the calling terminal belongs acquires the roaming code of the called terminal to connect to the called terminal, the called terminal number cannot be recognized, stopped or shut down, and the roaming is not obtained. The code causes the call to fail.

When the connection failure is caused by the connection failure of the MSC to which the called terminal of the call belongs, this step is specifically an IDP message sent by the MSC to which the called terminal of the SCP receives the call after the call connection fails. In this case, the reason for the connection failure may be that the MSC to which the called terminal belongs is connected to the called terminal, and the called terminal cannot be connected to the called terminal due to busy, inaccessible or no response of the called terminal, and the call fails. When the calling terminal and the called terminal of the call are located in different networks, the step is specifically that the SCP receives an IDP message sent by the corresponding gateway mobile switching center (GMSC) after the call connection fails, where The SCP is located on the same network as the GMSC that sent the IDP message. In this case, the MSC to which the calling terminal belongs directly connects the call to the GMSC in the network to which the calling terminal belongs, and the GMSC connects with the GMSC in the network to which the called terminal belongs, and further connects the called terminal to establish a call. If the called terminal is unable to connect, the two GMSCs of the network to which the primary called terminal belongs are respectively sent IDP messages to the SCPs in the respective networks to respectively trigger the intelligent network services corresponding to the primary and called users.

Step S102: The SCP acquires call information of the call included in the IDP message.

Step S103: The SCP triggers the corresponding intelligent network service according to the call information and the service logic of the intelligent network service customized by the calling terminal and/or the called terminal of the call.

In this step, the SCP confirms the intelligent network service customized by the calling terminal and/or the called terminal of the called terminal according to the information of the called terminal and the reason for the failure of the call connection in the obtained call information, and according to The corresponding business logic triggers the intelligent service.

The storage sub-module 131 is configured to store service logic of the customized intelligent network service of the terminal;

The obtaining sub-module 132 is configured to obtain, according to the call information acquired by the obtaining module 12, the storage sub-module 131, the service logic of the customized calling network service of the calling terminal and/or the called terminal of the called terminal; the triggering sub-module 133, The corresponding intelligent network service is triggered according to the service logic of the customized network service customized by the calling terminal and/or the called terminal of the call acquired by the obtaining sub-module 132.

The technical solutions proposed by the embodiments of the present invention are described below in conjunction with specific application scenarios.

When the user of the calling terminal dials the number of the called terminal and calls the user of the called terminal, the call setup process is triggered, including the calling process and the called process.

When the calling and called terminals belong to the same network, if the call connection fails due to the failure of the calling process establishment, the MSC to which the calling terminal belongs may customize the application enhancement logic through the mobile network.

(Customised Applications for Mobile network Enhanced Logic, CAMEL) DP2 or DP12 triggers the corresponding intelligent service to the SCP, that is, sends an IDP message containing the call information to the SCP.

The reason for the specific connection failure may be that when the MSC to which the calling terminal belongs acquires the roaming code of the called terminal to connect to the called terminal, the called terminal number cannot be recognized, stopped, or shut down, and the roaming code is not obtained, resulting in the call. failure. If the calling process is successfully established, but the call connection fails due to the failed establishment of the called process, the MSC to which the called terminal belongs triggers the corresponding intelligent service to the SCP through CAMEL DP2 or DP12, that is, the call information is sent to the SCP. IDP message.

The reason for the specific connection failure may be that the MSC to which the called terminal belongs is connected to the called terminal, and the called terminal cannot be connected to the called terminal due to the busy, inaccessible or non-responding reasons of the called terminal, and the call fails.

In this way, the implementation of the intelligent network service when the call connection between the terminals in the same network fails.

On the other hand, when the calling and called terminals belong to different networks, that is, when the called terminal is a user of the network with respect to the calling terminal, the MSC to which the calling terminal belongs directly connects the call to the gateway of the network to which the calling terminal belongs, that is, the The GMSC of the network, the GMSC is connected to the GMSC in the network to which the called terminal belongs, and further connects the called terminal to establish a call. If the called terminal is unable to connect, the two GMSCs of the network to which the primary called terminal belongs are respectively sent IDP messages to the SCPs in the respective networks to trigger the intelligent network services corresponding to the primary and called users respectively.

In this way, the implementation of the intelligent network service when the call connection between the different network terminals fails can be realized.

Further, the specific technical solution of the intelligent network service is taken as an example to describe the technical solution proposed by the embodiment of the present invention in detail.

For the convenience of description, in the following embodiments, the MSC to which the calling and called terminals belong is specifically a Visit Mobile Switch Center (VMSC), and such changes do not affect the protection scope of the present invention. FIG. 3 is a schematic flowchart diagram of a method for performing call forwarding after a call connection failure according to another embodiment of the present invention, and the specific description of the method is as follows:

Step S301: The terminal A sends an Initial Address Message (IMM) to the VMSC corresponding to the terminal B, requesting to establish a call to the terminal B.

In this embodiment, the call setup request is implemented by sending an IAM message including the information of the terminal A and the terminal B. This is only a preferred embodiment of the present invention, and other solutions that can achieve the same technical effects are also belong to the present invention. The scope of protection of the invention.

It should be noted that the foregoing terminal A sends an IAM message to the VMSC corresponding to the terminal B, and specifically, the network entity such as the VMSC corresponding to the terminal A sends the VMSC corresponding to the terminal B, and the change does not affect the present invention. protected range.

Step S302: The VMSC sends a Setup Call message to the terminal B to establish a call, but the terminal B cannot be connected, and the call connection fails.

The calling terminal A dials the called terminal B, and the terminal B fails to connect due to shutdown, busy or unreachable reasons.

Step S303: The VMSC corresponding to the terminal B sends an IDP message to the SCP.

Specifically, the VMSC corresponding to the terminal B customizes the application enhancement logic through the mobile network.

(Customized Applications for Mobile network Enhanced Logic, CAMEL) triggers the intelligent network, that is, sends an IDP message to the SCP, where the IDP message carries the primary and called numbers of the connection that failed to connect and the reason for the connection failure.

Step S304: The SCP parses the IDP message, analyzes the calling and called number and the reason for the connection failure, and triggers the call forwarding service according to the service logic. In a specific implementation scenario, the user corresponding to the terminal B customizes the call forwarding service. When the call to the terminal B cannot be connected, the call forwarding service is triggered, and the call is transferred to the terminal C for connection.

In this step, the specific operations performed by the SCP are: performing the service logic of the call forwarding service, changing the called number from the number of the terminal B to the number of the terminal C, thereby transferring the call of the terminal A to the terminal C.

Specifically, in the process of establishing a call from the terminal A to the terminal C as shown in FIG. 3, the technical solution used is the same as the existing call forwarding technology, and details are not described in this embodiment.

The technical solution of the embodiment of the present invention has the following advantages, because the call forwarding method after the call connection failure is used, thereby triggering the intelligent network service for the connection failure call, and the business logic of the subsequent call is controlled by the intelligent network, Save intelligent network resources and reduce the effect of voice loops.

FIG. 4 is a schematic flowchart of a method for performing a power-on reminder and a power leakage reminder after a call connection failure according to another embodiment of the present invention. The specific description of the method is as follows:

Step S401: The terminal A sends an IAM message to the VMSC corresponding to the terminal B, requesting to establish a call to the terminal B.

In this embodiment, the call setup request is implemented by sending an IAM message including the information of the terminal A and the terminal B. This is only a preferred embodiment of the present invention, and other solutions that can achieve the same technical effects are also in the present invention. The scope of protection.

Step S402: The VMSC sends a Setup Call message for establishing a call to the terminal B, but the terminal B cannot be connected, and the call connection fails. The calling terminal A dials the called terminal B, and the terminal B fails due to shutdown, busy or unreachable reasons.

Step S403: The VMSC corresponding to the terminal B sends an IDP message to the SCP.

Specifically, the VMSC corresponding to the terminal B triggers the intelligent network through the CAMEL, that is, sends an IDP message to the SCP, where the IDP message carries the primary and called numbers of the connection that failed to connect, and the reason for the connection failure.

Step S404: The SCP parses the IDP message, analyzes the calling and called number and the reason for the connection failure, and triggers the power-on reminder and the leakage reminding service according to the service logic.

In a specific implementation scenario, the user corresponding to the terminal A customizes the power-on reminding service, and when the call connection fails due to reasons such as the target terminal is not turned on, the terminal can be turned on or can be turned on when the target terminal is powered on. A sends a power-on reminder of the target terminal, prompting terminal A to perform a call operation.

On the other hand, the user corresponding to the terminal B customizes the leakage reminding service, and when the call to the terminal B cannot be connected, the leakage reminding service is triggered, and the terminal B is prompted to have a disconnected call.

In this step, the specific operations performed by the SCP are: recording related information of the current call connection failure, and executing the service logic of the power-on reminder and the leakage reminder, sending a leakage alert message to the terminal B, and when the terminal B can be connected, Send a power-on reminder message to terminal A.

Step S405: The SCP sends a call release message (Release Call, RC) to the VMSC corresponding to the terminal B.

The RC message is used to request the VMSC corresponding to the terminal B to release the current disconnected call.

Step S406: The VMSC corresponding to the terminal B sends a Release message, that is, a REL message, to the terminal A.

The Release message is used to request terminal A to release the current missed call. It should be noted that the VMSC corresponding to the terminal B sends a Release message to the terminal A, specifically to the network entity such as the VMSC corresponding to the terminal A. Such a change does not affect the protection scope of the present invention.

It should be noted that, in this embodiment, the situation that the power-on reminder and the leakage reminder service exist simultaneously is described. However, in the actual application scenario, other corresponding intelligent network services may be simultaneously performed due to different customized services of the user, or Only one of the intelligent network services is executed, and such changes do not affect the scope of protection of the present invention.

The technical solution of the embodiment of the present invention has the following advantages, because the method of performing the power-on reminder and the leakage reminder after the call connection failure is used, so that one or more intelligent network services can be triggered simultaneously for the call that fails to connect, and the intelligent network is triggered by the intelligent network. The business logic of controlling subsequent calls achieves the goal of saving intelligent network resources, reducing voice path, and achieving multi-service coordination.
