Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow diagram of an embodiment of a session-related network capability API charging method according to the present invention, and referring to fig. 1, the embodiment discloses a session-related network capability API charging method, including:
s1, after receiving a call request of an applied caller, sending a quota request message to an Online Charging System (OCS), and receiving a response message returned by the OCS according to the quota request message, wherein the response message carries quota information of a caller Application Program Interface (API) distributed by the OCS;
s2, after the call is finished, sending a feedback message, such as a CCR-T message, to the OCS, where the feedback message carries actually used quota information, so that the OCS charges according to the actually used quota information.
According to the session-related network capability API charging method provided by the embodiment of the invention, the OCS can be informed of the calling party API quota information so that the OCS can carry out charging according to the quota information, and therefore, online charging for the session-related network capability API can be realized.
It should be noted that the execution subject of the embodiment of the method is a network capability open platform.
Specifically, in step S1, the application of the user terminal sends a call request to the network capability opening platform, requesting to call a caller API of the network capability platform.
If the network capability open platform approves the call request, the application is allowed to call the calling party API and write the called number in the API interface parameter.
After the application calls the caller API, the network capability open platform sends a quota request message, such as a CCR-I message, to the OCS to request the OCS for a quota of the caller API. After receiving the quota request message, the OCS allocates a quota for the caller API according to the quota application information in the message, and returns a response message, such as a CCA-I message, to the network capability open platform to inform the network capability open platform of the allocation information of the quota of the caller API.
Wherein the quota is a resource corresponding to 1 unit cost. The specific value of the 1 unit cost and the size of the resource corresponding to the specific value can be adjusted according to the actual situation, which is not limited in this embodiment.
Further, after the network capability open platform sends the quota request message to the OCS, the network capability open platform sends a calling party capability calling request to the AS to indicate that the AS does not perform service online charging on the call.
Meanwhile, the network capability open platform also sends an indication message to the P-GW to indicate that the P-GW does not charge the call flow of the calling party.
And the network capability open platform can send the capability calling request and the indication message to the AS and the P-GW through the RESTful interface.
It should be noted that, when the AS and the P-GW suspend charging of the API of the calling party, the network capability open platform performs statistics and monitoring on the quota usage of the API of the calling party.
Further, in step S2, if the call is ended, the network capability open platform sends a feedback message, such as a CCR-T message, to the OCS to notify the OCS of quota information actually used by the API of the calling party in the call process. Therefore, the OCS charges the calling party API according to the quota information actually used by the calling party API in the feedback message, and returns a charging message, such as a CCA-T message, to the network capacity open platform to inform the charging information of the calling party API.
After the call is finished, the network capability open platform also sends an indication message to the P-GW and the AS to indicate the P-GW and the AS to recover the online charging of the service and the call flow.
Optionally, this embodiment further includes:
if the quota of the API of the calling party is used up in the call process, the network capability open platform sends a new quota request message, such as a CCR-U message, to the OCS, and receives a new response message, such as a CCA-U message, returned by the OCS according to the new quota request message, where the new response message carries quota information of the new API of the calling party, which is allocated by the OCS.
The session-related network capability API charging method provided by the embodiment of the invention has the advantages that the network capability open platform can enable the AS and the P-GW to suspend the online charging of the service of the calling party and the charging of the call flow, so that the repeated charging of the user terminal can be avoided while the API of the calling party is charged, and the session-related network capability API charging method provided by the embodiment of the invention has rationality and accuracy and has wide application prospect.
Fig. 2 is a schematic flowchart of an embodiment of the session-related network capability API charging method of the present invention, and referring to fig. 2, the embodiment discloses a session-related network capability API charging method, including:
s21, after receiving a quota request message sent by the network capability opening platform, allocating a quota to a caller API according to a quota request message of the caller API in the quota request message, and sending allocated quota information to the network capability opening platform through a response message, for example, a CCA-I message;
and S22, after the call is finished, receiving a feedback message, such as a CCR-T message, sent by the network capability open platform to acquire quota information actually used by the calling party API, and charging according to the quota information actually used.
According to the session-related network capability API charging method provided by the embodiment of the invention, quota information can be allocated, and charging can be carried out according to the quota use information reported by the network capability open platform, so that online charging for the session-related network capability API can be realized.
It should be noted that an execution subject of the embodiment of the present method is an OCS (Online Charging System).
Specifically, in step S22, the OCS may use a product of the used quota amount and a preset quota unit price as a charge generated by the API of the calling party in the current call process. The preset quota unit price can be adjusted according to actual conditions, which is not limited in this embodiment.
After completing charging of the calling party API, the OCS returns a charging message, such as a CCA-T message, to the network capability openness platform to inform the charging information of the calling party API.
Further, the method further comprises:
if the OCS receives a new quota request message sent by the network capacity open platform in the conversation process, allocating a new quota for the calling party API according to new quota application information of the calling party API in the new quota request message, and sending the new quota information to the network capacity open platform through a new response message.
Fig. 3 is a schematic information interaction diagram of an embodiment of a session-related network capability API charging method of the present invention, and referring to fig. 3, the embodiment of the present invention further discloses an audio and video network capability API online charging method, including:
and S31, the application sends a call request to the network capability open platform to call a calling party API of the network capability platform.
After the network capability platform approves the call request, the application calls the calling party API and writes the called number in the API interface parameter.
S32, the network capability openness platform sends a quota request message, such as a CCR-I message, to the OCS to request the OCS for a quota of the caller API.
Wherein the quota is a resource corresponding to 1 unit cost. The specific value of the 1 unit cost and the size of the resource corresponding to the specific value can be adjusted according to the actual situation, which is not limited in this embodiment.
S33, after receiving the quota request message sent by the network capability opening platform, the OCS allocates a quota to the caller API according to the quota request message of the caller API in the quota request message, and sends the allocated quota information to the network capability opening platform through a response message, for example, a CCA-I message.
And S34, after the network capability open platform sends the quota request message to the OCS, sending a calling party capability calling request to the AS so AS to indicate the AS not to perform service online charging on the call. And the AS does not perform service online charging on the call according to the indication information in the capability calling request.
Meanwhile, the network capability open platform also sends an indication message to the P-GW to indicate that the P-GW does not charge the call flow of the calling party. And the P-GW suspends the IMS APN traffic charging (the call traffic is carried on the IMS APN) according to the indication message and sends a traffic charging suspension message, such as a CCR-U message, to the OCS so as to inform the OCS that the call traffic charging is suspended. And after receiving the traffic charging suspension message, the OCS returns an acknowledgement message, such as a CCA-U message, to the P-GW for acknowledgement.
And the network capability open platform can send the capability calling request and the indication message to the AS and the P-GW through the RESTful interface.
It should be noted that, when the AS and the P-GW suspend charging of the API of the calling party, the network capability open platform performs statistics and monitoring on the quota usage of the API of the calling party.
It can be understood that after the AS and the P-GW suspend charging, the AS can perform the call flow: messages such AS Invite, 180/200, ACK and the like are interacted among the AS, the CSCF and the UE; when the called party answers, the call can be established.
And S35, after the call is finished, the network capability open platform sends a feedback message, such as a CCR-T message, to the OCS, wherein the feedback message carries actually used quota information, so that the OCS can charge according to the actually used quota information.
And the OCS charges the calling party API according to the quota information actually used by the calling party API in the feedback message and returns a charging message, such as a CCA-T message, to the network capacity open platform to inform the charging information of the calling party API.
The OCS may use a product of the used quota amount and a preset quota unit price as a charge generated by the API of the calling party in the current call process. The preset quota unit price can be adjusted according to actual conditions, which is not limited in this embodiment.
It should be noted that when the call is ended, messages such AS BYE/200 and the like are exchanged among the UE, the CSCF, and the AS sends the message of the end of the call to the network capability open platform, so that the network capability platform completes the quota usage statistics on the API of the calling party.
And S36, the network capability opening platform sends a state notification message to the application to inform the application that the call is ended.
Meanwhile, the network capability open platform also sends an indication message to the P-GW and the AS to indicate the P-GW and the AS to recover the online charging of the service and the call flow.
Optionally, after the step S34 and before the step S35, the present embodiment further includes:
s34', if the quota of the API of the calling party is used up during the call, the network capability open platform sends a new quota request message, such as a CCR-U message, to the OCS.
After receiving the new quota request message, the OCS allocates a new quota to the caller API according to the request message therein, and returns a new response message, such as a CCA-U message, to the network capability open platform to notify the network capability open platform of the new quota allocation information of the caller API.
