Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for controlling a transmission policy.
Background
Fig. 1 is a schematic diagram of an architecture of Policy and Charging Control (PCC) defined by the third Generation Partnership Project (3 GPP). As shown in fig. 1, a Policy and Charging Rules Function (PCRF) performs Quality of Service (QoS) and Charging Policy making for the traffic using network resources. The PCRF needs to combine service information received from an Application Function (AF), user Subscription information received from a Subscription database (SPR), a policy configured by an operator, and the like. The PCRF issues a control Policy formulated for the service to a Policy and Charging Enforcement Function (PCEF for short) or a Bearer Binding and Event reporting Function (BBERF for short) for execution. Meanwhile, the PCRF may subscribe to bearer layer related events from the PCEF and/or the BBERF, so as to sense the events in time and change the control policy when the bearer layer has the events. In addition, the PCEF and the Traffic Detection Function (TDF) can perform Application Detection and Control functions according to a PCC rule (PCEF) issued by the PCRF or an Application Detection and Control (ADC) rule (TDF).
To further open up mobile network capabilities to third party application providers, the network support provides a special time window for third party provisioning of the transfer context data. The third party application provides the context data related information that needs to be transmitted (such as the maximum number of UEs for the context data to be transmitted, the maximum amount of data transmitted per UE, etc.) to any PCRF in the operator network. And after the PCRF decides a transmission strategy according to the relevant information, the transmission strategy is sent to a third party application, and meanwhile, the PCRF stores the strategy in the SPR. The transmission policy includes charging rate, maximum bandwidth, time window, etc. When a third party application sends data number to a specific UE, a third party application AF sends service information to a PCRF of the UE to request QoS authorization, and the PCRF of the UE acquires a previously decided transmission strategy from an SPR at the moment and provides QoS authorization for the UE according to the transmission strategy. However, in the above scheme, the network does not have a method of controlling data of the UE according to a transmission policy. There has not been an effective solution to the above-mentioned problems in the related art.

12. The apparatus of claim 11, wherein the PCC rule further carries a third charging key and a time for executing the third charging key, and wherein the time for executing the third charging key is the time window expiration time.
13. The apparatus of claim 12, wherein the first sending module comprises:
and a third sending unit, configured to send the transmission policy expiration indication to the AF after determining that the time window of the transmission policy has expired, and provide the third charging key to the AF.
14. A control device of transmission strategy is applied to an application function entity (AF), and is characterized by comprising:
a providing module, configured to provide service information to a policy function entity, where the service information carries a reference identifier of a previously negotiated transmission policy;
a second receiving module, configured to receive, when the policy function entity determines that the time window of the transmission policy is expired, the transmission policy expiration indication or the authorization service information denial indication sent by the policy function entity, where the policy function entity is configured to obtain the transmission policy from a user subscription document repository SPR; when the policy function entity determines that the time window of the transmission policy is not expired, the policy function entity is further configured to formulate a policy and charging control PCC rule according to the transmission policy and provide the policy and charging control PCC rule to a policy enforcement function entity, where the PCC rule carries a first charging key in the transmission policy.
15. A control system for a transmission strategy, comprising the apparatus of any one of claims 8 to 13 and the apparatus of claim 14.
