Problems solved by technology

When OCS changes according to the police counter state (Police Counter), such as end user consumption balance, traffic balance, etc., it is necessary to send SNR (Spending-Status Notification Request, billing status notification request) messages to some online sessions, such as when the bandwidth policy is changed. , at this time OCS cannot determine which Sy sessions need to push SNR messages, therefore, it cannot provide accurate bandwidth control strategies for terminals

Embodiment 1

[0085] figure 1shows a structural block diagram of an OCS according to an embodiment of the present invention, figure 2 shows a structural block diagram of a PCEF according to an embodiment of the present invention, image 3 A structural block diagram of a PCRF according to an embodiment of the present invention is shown. Among them, the OCS, PCEF, and PCRF in this application are mainly used to control the bandwidth of multiple terminals using the same account, and a certain terminal is the focused terminal. When the focused terminal goes online, the PCEF and the PCRF pass The Gx interface establishes the Gx session of the concerned terminal, the PCRF establishes the Sy session of the concerned terminal through the Sy interface between the PCRF and the OCS, and the PCEF and the OCS establish the concerned terminal through the Gy interface Gy session. In a possible implementation manner, each session has a session ID for identifying the session, and each session carries t...

[0099] Figure 4 shows a structural block diagram of an OCS according to an embodiment of the present invention, Figure 5 A structural block diagram of a PCRF according to an embodiment of the present invention is shown. Figure 4 Winning mark and figure 1 The same components have the same functionality, Figure 5 Winning mark and image 3 The same components have the same functions, and detailed descriptions of these components are omitted for brevity.

[0100] like Figure 4 As shown, the main difference between this embodiment and the previous embodiment is that the OCS may further include an acquisition module 13 . The acquisition module 13 is connected to the establishment module 12, and is mainly used to obtain all the corresponding policy counters of the Gy session according to the association relationship established by the establishment module 12 when the Gy session causes the state of the corresponding policy counter on the OCS to change. Describe the Sy sess...

Embodiment 3

[0128] The terminal control method described in the embodiment of the present invention is mainly used to control the bandwidth of multiple terminals using the same account. A certain terminal is used as the concerned terminal. For the Gx session of the concerned terminal, the PCRF and the OCS establish the Sy session of the concerned terminal through the Sy interface, and the PCEF and the OCS establish the Gy session of the concerned terminal through the Gy interface.

[0129] Figure 7 A flow chart showing a terminal bandwidth control method at the OCS side according to an embodiment of the present invention. like Figure 7 As shown, the terminal bandwidth control method on the OCS side may mainly include the following steps:

[0130] Step S101, the OCS receives the first credit control request message carrying the session identifier of the Sy session and the session identifier of the Gy session sent by the PCEF through the Gy session, wherein the first credit control requ...

Abstract

The invention relates to an OCS (Online Charging System), a PCEF (Policy and Charging Enforcement Function), a PCRF (Policy and Charging Rules Function) and a terminal bandwidth control method. The OCS comprises a first receiving module, and a building module. The first receiving module is used for receiving a session identifier with an Sy session sent by the PCEF via a Gy session and a first credit control request message of a session identifier of the Gy session, and the first credit control request message is used for requesting to carry out authentication reservation on the concerned terminal. The building module is connected with the first receiving module for building and storing correlation between the Sy session and the Gy session according to the first credit control request message. According to the OCS, the PCEF, the PCRF and the terminal bandwidth control method, accurate bandwidth control can be provided for different terminals using the same account, the message amount between the OCS and the PCRF is reduced, and the interactive performance between devices is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an OCS, PCEF, PCRF and a terminal bandwidth control method. Background technique [0002] PCRF (Policy and Charging Rules Function) in 3GPP (The3rd Generation Partnership Project) controls the Qos (Quality of Service) of users and services. Provide differentiated services for users, allowing operators to implement more refined service control and billing methods based on service and user classification. When it is necessary to control the bandwidth of the user's Internet access, the PCRF makes a bandwidth policy decision for the user. When a user surfs the Internet, OCS (online charging system, online charging system) will generate two sessions, one is a session initiated by PCRF to OCS through the Sy interface, called Sy session (Session), and the other is GGSN (Gateway GPRS The PCEF (Policy and Charging Enforcement Fucntion, Policy and Charging Enforcement Func...
