[0126] The first embodiment: policy control based on QoS intervals when establishing or modifying a bearer initiated by a UE.

[0127] In this embodiment, the UE sends a request to the PCEF to establish (or modify) a bearer; after receiving the request sent by the UE, the PCEF applies to the PCRF for authorization of the QoS interval; The section is issued to the PCEF; the PCEF selects the appropriate QoS from the QoS section for policy control according to the resource usage status.

[0128] Figure 4 It is a flow chart of the policy control method in the first embodiment of the present invention. Such as Figure 4 As shown, the policy control method in the first embodiment of the present invention includes the following steps:

[0129] Step 401, the UE initiates a request to the PCEF for IP-CAN bearer establishment or modification (in the GPRS system, it is a secondary PDP context establishment or modification request);

[0130] Step 402, PCEF requests QoS or...

[0140] The second embodiment: policy control based on QoS intervals when an internal event of the PCEF is triggered.

[0141] In this embodiment, when the PCEF is triggered by an internal event (for example, an event in the event trigger list occurs), the PCEF applies to the PCRF for the authorization of the QoS interval; the PCRF authorizes the QoS interval through decision-making, and issues the authorized QoS interval to the PCEF , PCEF selects the appropriate QoS from the QoS interval for policy control according to the resource usage status.

[0142] Figure 5 It is a flow chart of the policy control method in the second embodiment of the present invention. Such as Figure 5 As shown, the policy control method in the second embodiment of the present invention includes the following steps:

[0143] Step 501, PCEF is triggered by an internal event, for example, a QoS change event trigger is triggered;

[0144] Step 502, PCEF applies to PCRF for authorization ...

[0152] Embodiment 3: Policy control based on QoS intervals when an AF session is established or modified.

[0153] In this embodiment, the establishment or modification process of the AF session triggers the PCRF to make an authorization decision on the QoS interval for the bearer or service flow, generates an authorized QoS interval, and actively sends it to the PCEF through the Diameter Authentication Authorization Request (AAR) message , PCEF selects the appropriate QoS from the QoS interval for policy control according to the resource usage status.

[0154] Figure 6 It is a flow chart of the policy control method in the third embodiment of the present invention. Such as Figure 6 As shown, the policy control method in the third embodiment of the present invention includes the following steps:

[0155] Step 601, establishment or modification of an AF session;

[0156] Step 602, the PCRF authorizes the QoS interval through decision-making;

[0157] Step 6...

Abstract

The invention discloses a strategy control method, including: a PCRF trigging a strategy for authorization QoS range according to trigger events, carrying out the strategy according to the strategy information, generating a corresponding authorization QoS range, and sending the newly generated authorization QoS range to a PCEF; noticing the PCEF to carry out QoS control according to the selected information and the newly generated authorization QoS range. The invention further discloses a strategy control system, the system including the PCRF and the PCEF. The PCEF can carry out the QoS control in the combination with resource performance and strategy predefined by an operator according to the authorization QoS range by using the method and system, so that the PCEF can carry out flexible QoS adjustment in the limitation of network resources to satisfy the requirements of user high-quality service, thereby implementing reasonable allocation of network resources.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a policy control method and system. Background technique [0002] Communication networks are evolving from traditional circuit switched (CS, Circuit Switched) networks to packet switched (PS) networks that use IP as a bearer. When providing carrier-class services (especially real-time services, such as video calls) in an IP network, end-to-end quality of service (QoS, Quality of Service) issues need to be considered to meet user requirements for communication quality. In addition, because the IP network can also provide various other services, such as web page browsing, file download, video streaming on demand, etc., the IP network also needs to have the ability to charge according to different service flows and different QoS. [0003] To address these requirements, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) defines a Policy and Ch...
