The service resource create request is used to request the charging system to create a second service resource and a third service resource, wherein the second service resource corresponds to an online charging service in the session, and the third service resource corresponds to an offline charging service in the session.
During specific implementation, the charging system may identify the second service resource and the third service resource by using different resource identifiers.
Case 3: When the services in the session include an online charging service and an offline charging service, the charging trigger apparatus sends two service resource create requests to the charging system, wherein one service resource create request is used to request the charging system to create a service resource corresponding to the online charging service in the session, and the other service resource create request is used to request the charging system to create a service resource corresponding to the offline charging service in the session.
It should be noted that in Case 3, different attribute or identifier information may be used, so that the charging system can distinguish between the service resource create request used to request the charging system to create the service resource corresponding to the online charging service in the session and the service resource create request used to request the charging system to create the service resource corresponding to the offline charging service in the session.
Case 4: One service resource create request corresponds to a plurality of service resources, and the plurality of service resources corresponding to the service resource create request are service resources corresponding to services in one session.
A possible specific implementation is: The charging trigger apparatus sends a service resource create request to the charging system, the service resource create request is used to create a plurality of service resources, and each service resource corresponds to a service, in the session, that belongs to a same rating group. For example, if one session includes a service belonging to a rating group 1 and a service belonging to a rating group 2, the charging trigger apparatus sends a service resource create request for the session. The service resource create request is used to request to create two service resources, one service resource corresponds to the rating group 1, and the other service resource corresponds to the rating group 2.
During specific implementation, the charging system may identify the service resources by using different resource identifiers.
It should be noted that in this embodiment of this disclosure, the service resource create request, without carrying any quota request information or any reported usage information, may be used to create a service resource, and the service resource is used to manage requesting for a quota for the service in the session and/or manage reporting of usage information of the service in the session. Specifically, requesting for a quota for an online charging service, reporting of usage information of an offline charging service, or requesting for a virtual quota for an offline charging service is subsequently completed through a service resource update operation.
In addition, in this embodiment of this disclosure, when the service corresponding to the service resource that the charging system is requested to create by the service resource create request includes an online charging service, the service resource create request may further include quota request information for the online charging service and a rating group corresponding to the quota request information.
In this embodiment of this disclosure, when the service corresponding to the service resource that the charging system is requested to create by the service resource create request includes an offline charging service, the service resource create request may further include a requested virtual quota for the offline charging service and a rating group corresponding to the requested virtual quota; or when the service corresponding to the service resource that the charging system is requested to create by the service resource create request includes an offline charging service, the service resource create request may further include usage information of the offline charging service and a rating group corresponding to the usage information.
In this embodiment of this disclosure, the quota request information for the online charging service and the rating group corresponding to the quota request information, the usage information of the offline charging service and the rating group corresponding to the usage information, and the requested virtual quota for the offline charging service and the rating group corresponding to the requested virtual quota, all of which are carried in the service resource create request, are identified by using different attributes or flags, so that the charging system can distinguish among them for processing.
The rating group is used to aggregate one or more services having a same charging rate, to help the charging system perform rating.
For example, when the service corresponding to the service resource that the charging system is requested to create by the service resource create request includes an online charging service and an offline charging service, optionally, the service resource create request may further include quota request information for the online charging service and a rating group corresponding to the quota request information, and usage information of the offline charging service and a rating group corresponding to the usage information. The charging trigger apparatus may distinguish, by using different attribute or flag information, between the quota request information for the online charging service and the rating group corresponding to the quota request information, and the usage information of the offline charging service and the rating group corresponding to the usage information. For example, a specific implementation of the service resource create request is shown in Table 1:
For another example, the service resource create request implemented by using a RESTful interface is shown in Table 2. In the service resource create request, the attribute “serviceResource” indicates the service resource and “subscriber IMSI” indicates the user identifier.
For example, when the service corresponding to the service resource that the charging system is requested to create by the service resource create request includes an online charging service and an offline charging service, optionally, the service resource create request may further include quota request information for the online charging service, a rating group corresponding to the quota request information, a requested virtual quota for the offline charging service and a rating group corresponding to the requested virtual quota. A specific implementation of the service resource create request is shown in Table 3:
Specifically, for the request for a quota for the online charging service, that the charging system reserves, from account balance of the user equipment, a quota that corresponds to the rating group and that is requested by using the service resource create request, and allocates the quota to the online charging service may be applied to a case in which the service resource create request further includes the quota request information for the online charging service and the rating group corresponding to the quota request information. For another example, for the request for a virtual quota for the offline charging service, that the charging system allocates, to the offline charging service, a virtual quota that corresponds to the rating group and that is requested by using the service resource create request, without reserving the virtual quota from account balance of the user equipment may be applied to a case in which the service resource create request further includes the requested virtual quota for the offline charging service and the rating group corresponding to the requested virtual quota. Alternatively, for another example, that the charging system generates a charging data record, based on the usage information of the offline charging service and the rating group corresponding to the usage information may be applied to a case in which the service resource create request further includes the usage information of the offline charging service and the rating group corresponding to the usage information.
For example, when the service resource create request is as shown in Table 2, the charging system reserves a quota of “10 M traffic volume” from the account balance for the online charging service whose user identifier is the IMSI, session identifier is “023152120”, flag “opType” is “Requested”, and rating group is “001”; and generates a charging data record with the usage information “25 M traffic volume” for the offline charging service whose user identifier is the IMSI, session identifier is “023152120”, flag “opType” is “Reported”, and rating group is “002”.
It should be further noted that in this embodiment of this disclosure, the charging system may perform corresponding processing for the service resource create request according to a locally configured policy, or may perform corresponding processing for the service resource create request according to a configuration policy delivered by the charging policy apparatus such as the PCF.
In addition, if event-based charging needs to be performed for an event or an event group of a service, the charging system creates, based on a request of the charging trigger apparatus, a service resource corresponding to the event or the event group of the service, specifies a validity period for the service resource, subtracts, from a user account, charges spent by the service, and generates a resource identifier. The resource identifier is used to identify the service resource. If the service fails, the charging trigger apparatus sends a service resource delete request, and the service resource delete request includes the resource identifier and identification information instructing the charging system to return, to the user account, the charges that are spent by the service corresponding to the service resource identified by the resource identifier and that are subtracted from the user account. If the service succeeds, the charging trigger apparatus does not need to send the service resource delete request, and after the validity period expires, the charging system automatically deletes the service resource.
In this embodiment of this disclosure, in step 502, the service resource create response sent by the charging system to the charging trigger apparatus may further include a user identifier and a session identifier, so that the charging trigger apparatus can distinguish among services corresponding to the service resource identified by the first service resource identifier.
It should be noted that when the charging system has granted the quota to the online charging service, or has granted the virtual quota to the offline charging service, the service resource create response may further include granted quota information or granted virtual quota information.
During specific implementation, the quota granted to the online charging service and the virtual quota granted to the offline charging service correspond to different attribute or flag information in the response message, so that the charging trigger apparatus can distinguish between them.
Optionally, the charging system may further generate a re-authentication trigger condition, and send the re-authentication trigger condition to the charging trigger apparatus, so that the charging trigger apparatus reports corresponding information when the re-authentication trigger condition is met. A specific re-authentication trigger condition may correspond to the service resource, or may correspond to a service corresponding to the service resource. The re-authentication trigger condition may alternatively be sent to the charging trigger apparatus by using the service resource create response. For example, the re-authentication trigger condition is that a usage amount of the online charging service is greater than or equal to the quota granted to the online charging service, or that the session is interrupted.
In addition, for the quota request information sent by the charging trigger apparatus, the charging system may further determine whether to grant the quota or whether to allow user equipment to directly use the service without any quota granted. If a determining result is that the service is an offline charging service that can be directly used without any quota granted, the service resource create response may further include an indication indicating that no granting needs to be performed. When the service, in the session, that belongs to a same rating group, corresponds to one service resource, if the charging system determines that the same rating group corresponds to both an actual quota and a virtual quota, the service resource create response further carries flow information corresponding to the granted quota (for example, a flow identifier or a flow feature information of the quota), so that the charging trigger apparatus separately manages, for the same rating group based on the flow identifier or the flow information, use of the actual quota and the virtual quota that are granted by the charging system.
For example, the service resource create response may be shown in Table 4.
In another example, the service resource create response is shown in Table 5.
It should be further noted that optionally, in this embodiment of this disclosure, if the charging system fails to create the service resource, the charging system sends a response indicating that the service resource fails to be created, to notify the charging trigger apparatus that the service resource fails to be created. In this case, to ensure successful use and charging of the service, the charging trigger apparatus may resend the service resource create request to another charging system.
In addition, to ensure successful use of the service by the user and accuracy of charging for the service, the charging trigger apparatus sends a service resource update request to the charging system, the service resource update request includes a second resource identifier, and the second resource identifier is used to identify a service resource, in the service resource identified by the first resource identifier, that the charging system is requested to update. After receiving the service resource update request sent by the charging trigger apparatus, the charging system correspondingly updates the service resource based on the service resource update request.
It should be noted that the second resource identifier may be the first resource identifier, or may be an identifier of part of the resource identified by first resource identifier. Specifically, whether the second resource identifier is the first resource identifier or an identifier of part of the resource identified by first resource identifier may be determined by the charging system based on an actual case. For example, the first resource includes a service resource identified by a resource identifier 1 and a service resource identified by a resource identifier 2, if the service resource identified by the resource identifier 2 needs to be updated while the service resource identified by the resource identifier 1 remains unchanged, the second resource identifier is the resource identifier 2. For another example, when the first resource identifier is used to identify one service resource, and the service resource identified by the first resource identifier needs to be updated, the second resource identifier is the first resource identifier.
It should be understood that, during specific implementation, in example 1: when the service corresponding to the service resource identified by the second resource identifier includes an online charging service, the service resource update request may further include quota request information for the online charging service, a rating group corresponding to the quota request information, usage information of the online charging service and a rating group corresponding to the usage information. In this case, after receiving the service resource update request, the charging system may further reserve, from account balance of the user equipment, a quota that corresponds to the rating group and that is requested by using the service resource create request, allocates the quota to the online charging service, and subtract, from the quota allocated to the online charging service based on the usage information of the online charging service and the rating group corresponding to the usage information, a part used by the online charging service. Such technical solution may be applied to a case in which the granted quota of the online charging service in the session is used up.
In example 2, when the service corresponding to the service resource identified by the second resource identifier includes an online charging service, the service resource update request may further include quota request information for the online charging service and a rating group corresponding to the quota request information. In this case, after receiving the service resource update request, the charging system may further reserve, from account balance of the user equipment, a quota that corresponds to the rating group and that is requested by using the service resource create request, and allocates the quota to the online charging service. Such technical solution may be applied to a case in which there is a new online charging service having no granted quota in the session.
In example 3, when the service corresponding to the service resource identified by the second resource identifier includes an online charging service, the service resource update request may further include usage information of the online charging service and a rating group corresponding to the usage information. In this case, after receiving the service resource update request, the charging system may further subtract a part used by the online charging service from a quota allocated to the online charging service. Such technical solution may be applied to a case in which the granted quota of the online charging service in the session is not used up.
In example 4, when the service corresponding to the service resource identified by the second resource identifier includes an offline charging service, the service resource update request may further include a requested virtual quota for the offline charging service, a rating group corresponding to the requested virtual quota, usage information of the offline charging service and a rating group corresponding to the usage information. In this case, after receiving the service resource update request, the charging system may further allocate, to the offline charging service, a virtual quota that corresponds to the rating group and that is requested by using the service resource create request, and generate a charging data record based on the usage information of the offline charging service and the rating group corresponding to the usage information. Such technical solution may be applied to a case in which the granted virtual quota of the offline charging service in the session is used up.
In example 5, when the service corresponding to the service resource identified by the second resource identifier includes an offline charging service, the service resource update request may further include a requested virtual quota for the offline charging service and a rating group corresponding to the requested virtual quota. In this case, after receiving the service resource update request, the charging system may further allocate, to the offline charging service, a virtual quota that corresponds to the rating group and that is requested by using the service resource create request. Such technical solution may be applied to a case in which there is a new offline charging service having no granted virtual quota in the session.
In example 6, when the service corresponding to the service resource identified by the second resource identifier includes an offline charging service, the service resource create request may further include usage information of the offline charging service and a rating group corresponding to the usage information. In this case, after receiving the service resource update request, the charging system may further generate a charging data record based on the usage information of the offline charging service and the rating group corresponding to the usage information. Such technical solution may be applied to a case in which there is an offline charging service in the session.
It should be noted that technical solutions of example 1, example 2, example 3, example 4, example 5, and example 6 may be used together, and optionally, when the technical solution of example 6 is used, technical solutions of example 4 and example 5 may be interchanged for use, or the technical solution of example 4 may be interchanged for use, or the technical solution of example 5 may be interchanged for use.
In this embodiment of this disclosure, the quota request information for the online charging service and the rating group corresponding to the quota request information, the usage information of the online charging service and the rating group corresponding to the usage information of the online charging service, the usage information of the offline charging service and the rating group corresponding to the usage information of the offline charging service, and the requested virtual quota for the offline charging service and the rating group corresponding to the requested virtual quota, all of which are carried in the service resource create request, are identified by using different attribute or flag information, so that the charging system can distinguish among them for processing.
In addition, when the service resource update request includes the usage information (such as the usage information of the online charging service or the usage information of the offline charging service) of the service, the service resource update request may further include a reason for reporting the usage information of the service, for example, the granted quota of the online charging service is used up, or the session is interrupted.
Specifically, when the service resource update request includes information such as the quota request information for the service or the usage information of the service, the information may be carried in a uniform resource locator (URL) of the service resource update request, or may be carried in a message header of the service resource update request, or may be carried in a message body of the service resource update request. The place where the information is carried is not limited in this disclosure.
In an example, a specific implementation of the service resource update request may be shown in Table 6.
For another example, the service resource update request implemented by using the RESTful interface is shown in Table 7. In the service resource update request, the attribute “serviceResource” indicates the service resource and “subscriber” indicates a user.
Specifically, this embodiment of this disclosure further provides a manner of triggering the charging trigger apparatus to send the service resource update request to the charging system:
A possible triggering manner is: When a first trigger condition is met, the charging trigger apparatus sends the service resource update request to the charging system. For example, the first charging trigger condition may be that the charging trigger apparatus determines that the quota granted to the online charging service is used up. For another example, the first charging trigger condition is the re-authentication condition delivered by the charging system. For still another example, the first charging trigger condition is that a status of the service satisfies a preconfigured reporting condition (for example, the service is ended or a network type is changed).
Another possible trigger manner is: The charging system sends a service resource update notification to the charging trigger apparatus, the notification includes a third resource identifier, and the third resource identifier is used to identify a service resource, in the service resource identified by the first resource identifier, that the charging system requests to be updated. After receiving the service resource update notification, the charging trigger apparatus reports the service resource update request to the charging system. The service resource update request includes the second resource identifier, and the second resource identifier may be the third resource identifier; or may include the third service resource identifier and an identifier of another to-be-updated service resource determined by the charging trigger apparatus.
Further, the service resource update request further includes a rating group to which a service for which the charging system requests a service resource to be updated belongs, and the service is in the services corresponding to a service resource identified by the third resource identifier.
For example, a possible implementation of the service resource update notification is shown in Table 8.
For example, the service resource update notification implemented by using the RESTful interface is shown in Table 9, the attribute “subscriber” indicates the user and “pdusessionID” indicates the session identifier.
In this embodiment of this disclosure, after updating the corresponding service resource based on the service resource update request, the charging system may further return a service resource update response to the charging trigger apparatus. Specifically, the service resource update response is used to indicate, to the charging trigger apparatus, whether the charging system has updated the service resource.
Optionally, the service resource update response may further include information such as the quota granted to the online charging service or the virtual quota granted to the offline charging service. When the service resource update response includes both the quota granted to the online charging service and the virtual quota granted to the offline charging service, the quota granted to the online charging service and the virtual quota granted to the offline charging service correspond to different flags or attributes, so that the charging trigger apparatus can distinguish between them.
In an example, a possible implementation of the service resource update response may be shown in Table 10.
For another example, the service resource update response implemented by using the RESTful interface is shown in Table 11. In the service resource update response, the attribute “serviceResource” indicates the service resource and “subscriber” indicates the user.
To improve resource utilization ratio in the charging system, optionally, when a second charging trigger condition is met, the charging trigger apparatus sends a service resource delete request to the charging system, the service resource delete request includes a fourth resource identifier, and the fourth resource identifier is used to identify a service resource to be deleted from the service resource identified by the first resource identifier. After receiving the service resource delete request, the charging system deletes the service resource identified by the fourth resource identifier.
It should be noted that the second charging trigger condition may be sent by the charging policy apparatus to the charging trigger apparatus, or may be a policy configured by the charging trigger apparatus locally. For example, the second charging trigger condition is that a service corresponding to the service resource is interrupted, or the session is ended.
During specific implementation, when the service corresponding to the service resource identified by the fourth resource identifier includes an online charging service, the service resource delete request may further include usage information of the online charging service and a rating group corresponding to the usage information. In this case, the charging system subtracts, from a quota for the online charging service based on the usage information of the online charging service and the rating group corresponding to the usage information, a part used by the online charging service. Such subtraction may be applied to a case in which the service resource delete request further includes the usage information of the online charging service and the rating group corresponding to the usage information. When the service corresponding to the service resource identified by the fourth resource identifier includes an offline charging service, the service resource delete request may further include usage information of the offline charging service and a rating group corresponding to the usage information. In this case, the charging system generates a charging data record based on the usage information of the offline charging service and the rating group corresponding to the usage information, and such technical solution may be applied to a case in which the service resource delete request further includes the usage information of the offline charging service and the rating group corresponding to the usage information.
When the service resource delete request includes usage information of a service (such as usage information of an online charging service or usage information of an offline charging service), the service resource delete request may include a reason for reporting the usage information of the service.
Specifically, the foregoing content may be carried in a URL of the service resource delete request, or may be carried in a message header of the service resource delete request, or may be carried in a message body of the service resource delete request.
It should be understood that, different content, such as the usage information of the online charging service or the usage information of the offline charging service, included in the service resource delete request may be identified by using different or flag information, so that the charging system can distinguish among them for processing.
Alternatively, when a service resource corresponding to an online charging service is different from a service resource corresponding to an offline charging service, different service resource delete requests may be used to request the charging system to delete the service resource corresponding to the online charging service and the service resource corresponding to the offline charging service. In the case when a service resource delete request includes usage information of a service, usage information of an online charging service and usage information of an offline charging service may be carried in different service resource delete requests.
In an example, a possible implementation of the service resource delete request may be shown in Table 12.
For another example, the service resource delete request implemented by using the RESTful interface is shown in Table 13. In the service resource delete request, the attribute “serviceResource” indicates the service resource and “subscriber” indicates the user.
In this embodiment of this disclosure, after the charging system deletes the service resource based on the service resource delete request, optionally, the charging system may further send a service resource delete response to the charging trigger apparatus, and the service resource delete response is used to notify the charging trigger apparatus of the deleted service resource.
In embodiments of this disclosure, different messages, such as the service resource create request, the service resource update request, and the service resource delete request, may be distinguished by a name of a hypertext transfer protocol (HTTP) method, a name of an application programming interface (API), a specific identifier in an API, or the like, used by an application.
The solutions provided in this disclosure are mainly described above from a perspective of interaction between network elements. It can be understood that, to implement the foregoing functions, the network elements include corresponding hardware structures and/or software modules for performing the functions. A person of ordinary skill in the art should easily be aware that, in combination with the example units, algorithms, and steps described in the embodiments disclosed in this disclosure, this disclosure may be implemented by using hardware or a combination of hardware and computer software. Whether a function is performed by hardware or hardware driven by computer software depends on particular applications and design constraints of the technical solutions. A person skilled in the art may use different methods to implement the described functions for each particular application, but it should not be considered that the implementation goes beyond the scope of this disclosure.
