Problems solved by technology

[0006] The inventor found in the process of realizing the present invention that: the granularity of the policy control in the prior art is the Internet Protocol Access Network (IP-CAN, Internet Protocol Connectivity Access Network) connection initiated by the user terminal, that is, the system targets each IP-CAN The connections are all subject to policy control (including QoS control and billing control), and since the same user may establish multiple IP-CAN connections at the same time, different IP-CAN connections of the same user are separately policyd in the prior art control, resulting in a waste of system resources;
[0007] Secondly, in the prior art, the policy control method for IP-CAN connections cannot be effectively controlled for users with multiple IP-CAN connections, which reduces the flexibility of policy control

[0127] see Figure 4 , the fourth embodiment of the policy control method in the embodiment of the present invention includes:

[0128] 401. The user terminal sends a local connection establishment request message to the access gateway;

[0129] The user terminal sends a local connection establishment request message to the access gateway, requesting establishment of a local IP connection, such as allocating a local IP address, establishing an IPsec tunnel from the terminal to the access gateway, and so on.

[0130] 402. The access gateway sends a gateway policy control session establishment request message to the policy decision entity;

[0131] The access gateway BBERF sends a gateway policy control session establishment request message to the policy decision-making entity to establish a user-granular policy control session. The establishment request message carries user identification information and may also carry the user's current access network information (access netw...

Abstract

The embodiment of the invention discloses a policy control method, a communication system and related equipment, which are used for performing policy control to reduce the consumption of a system resource and improve the flexibility of the policy control for a user. The method provided by the embodiment of the invention comprises the following steps: receiving a policy control session request by apolicy decision-making entity, wherein the policy control session request comprises user identification or session identifier; generating a user policy control rule corresponding to the user identification or the session identifier; and sending the user policy control rule. The embodiment of the invention also provides a communication system and related equipment. The method, the system and the related equipment can effectively perform the policy control to reduce the consumption of the system resource and improve the flexibility of the policy control for the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a policy control method, a communication system and related equipment. Background technique [0002] With the development of network technology, the latest network architecture has attracted more and more attention from users. In the logical architecture of the next-generation mobile communication network, user terminals access through a local wireless access network. The access gateway is the convergence point of the access network, responsible for connection management and data forwarding related to access technology. The data gateway is the gateway for accessing the packet data network. It is responsible for the data connection management and data forwarding of the user accessing the packet data network. It is also the anchor point for mobile users to provide mobile services. The next-generation mobile communication network also enhances policy control functions, including Q...
