example 1
[0052] Figure 4 It is a QoS policy-based charging method for RACS according to Example 1 of the present invention. When a user dynamically initiates a certain service, if the service requires QoS guarantee, the process of dynamically issuing QoS and charging policies will be triggered. Such as Figure 4 As shown, the method includes the following steps:
[0053] Step S402, when the AF conducts session negotiation on a service with the UE, triggering the process of requesting resources for the service flow;
[0054] Step S404, AF sends a policy request to SPDF according to the resources and QoS required by the service;
[0055] Step S406, SPDF authorizes the request according to the operator's policy; and according to the service type, service priority, and the QoS required by the service (including maximum uplink and downlink bandwidth, average uplink and downlink bandwidth, transmission delay, jitter, etc.), And the billing-related policies preconfigured by the operator ...
example 2
[0068] Figure 5 It is a QoS policy-based charging method for RACS according to Example 2 of the present invention. When a user terminates a certain service, if the service requires QoS guarantee, it needs to initiate policy withdrawal processing to the RACS. Such as Figure 5 As shown, the method includes the following steps:
[0069] Step S502, when the AF receives the service termination message or the AF initiates the service termination, triggers the corresponding policy revocation process;
[0070] Step S504, the AF sends a policy revocation request to the SPDF;
[0071] Step S506, SPDF sends a policy revocation request to the x-RACF related to the service;
[0072] Step S508, x-RACF releases the resources related to the service, checks the RCEF related to the service, and sends a policy revocation request to the corresponding RCEF;
[0073] Step S510, RCEF receives a policy revocation request, deletes the policy, and interacts with the charging system to terminate ...

Abstract
The invention discloses a charging method based on the service quality strategy and a resource admission control subsystem. Wherein, the method includes adding a charging decision-making functional entity on a strategy decision-making functional entity based on the service, wherein, the charging decision-making functional entity is utilized to generate a charging strategy; the strategy decision-making functional entity based on the service receives a strategy request from an application functional entity, the charging decision-making functional entity generates the charging strategy accordingto the service description information contained in the strategy request; the strategy decision-making functional entity based on the service transmits the strategy request carrying the charging strategy to an access resource admission control functional entity and a boundary gateway functional entity that participates in the charging process. The invention enables the resource admission control subsystem to support the charging function based on the QoS strategy.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a quality of service (Quality of Service, QoS for short) policy-based charging method and a resource admission control subsystem. Background technique [0002] Next Generation Network (NGN for short) is a hot research topic in the field of current communication standards, which adopts IP and other packet technologies as bearer network technology to integrate fixed communication and mobile communication. NGN can provide richer multimedia services, such as emerging services with real-time requirements (such as VoIP, video conferencing, multimedia distance learning, video on demand, etc.), these services require the communication network to provide efficient end-to-end QoS support; The requirements for network service quality are getting higher and higher. Therefore, how to provide end-to-end QoS will be one of the core issues of NGN. [0003] The standard organization TISPAN (T...
