Embodiment 1

[0060] This embodiment describes that the load sensing function collects the traffic flow information of the service flow carried out by each user, based on which the load information of each cell is counted, and then the congestion status of the cell is judged. When a new service starts, the PCRF obtains the cell congestion status from the load sensing function according to the cell information. If it is congested, new services are rejected to alleviate network congestion. figure 2 It is a flow chart of a wireless access network congestion policy management method according to Embodiment 1 of the present invention, as shown in figure 2 As shown, the wireless access network congestion policy management method in this example includes the following steps:

[0061] Step 201, the user accesses the network, and establishes an IP-CAN session between the GGSN and the PCRF.

[0062] Step 202, the user conducts business.

[0063] In step 203, the GGSN reports the flow information...

Embodiment 2

[0077] This embodiment describes that the load sensing function collects the flow information of the service flow carried out by each user, and the RAN reports the identification information of the user and the latest cell information used to the load sensing function, and the load sensing function counts each cell based on this The load information of the cell, and then judge the congestion status of the cell. When a new service starts, the PCRF obtains the cell congestion status from the load sensing function according to the cell information. If it is congested, new services are rejected to alleviate network congestion. image 3 It is a flowchart of a method for managing congestion policies in a wireless access network according to Embodiment 2 of the present invention, as shown in image 3 As shown, the wireless access network congestion policy management method in this example includes the following steps:

Embodiment 3

[0096] This embodiment describes that when each user accessing the network conducts services, the P-GW reports the flow information of each user's service flow to the load sensing function, and the load sensing function counts the congestion status of each cell. If the cell is congested, the load sensing function actively notifies the PCRF to start the congestion strategy to alleviate the congestion. Figure 4 It is a flowchart of a method for managing congestion policies in a wireless access network according to Embodiment 3 of the present invention, as shown in Figure 4 As shown, the wireless access network congestion policy management method in this example includes the following steps:

[0097] Step 401, the user accesses the network, and establishes an IP-CAN session between the P-GW and the PCRF. It is possible for different users to access the network to select different P-GWs and PCRFs. In this example, the user selects P-GW-1 or P-GW-2 as an example to illustrate the...

Abstract

Disclosed are a radio access network congestion management method and apparatus, applied in a Policy and Charging Control (PCC) architecture, a load sensing function being provided in the PCC architecture. The method comprises: the load sensing function acquiring traffic information of each user equipment (UE) and information about a cell which the UE accesses, collecting statistics on the load of each cell, and determining a congested state of each cell according to the load of each cell. Also disclosed are a radio access network congestion strategy management method and system. The present invention enhances the load control capability of the PCC architecture, avoids cell call drop, unsmooth access, and other situations of reduced service quality from occurring in some cells of the network due to load congestion, and provides better service quality for the user.

Description

technical field [0001] The present invention relates to a load processing technology in a Policy and Charging Control (PCC, Policy and Charging Control) framework, in particular to a wireless access network congestion management method and device, and a wireless access network congestion policy management method and system. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) defines a policy and charging control (PCC, Policy and Charging Control) architecture for mobile networks, such as figure 1 As shown, the following briefly introduces the connection relationship between entities and their functions. [0003] Policy and Charging Rules Function (PCRF, Policy and Charging Rules Function), used to formulate resource control policies for service data streams using network resources during transmission; resource control policies include Quality of Service (QoS, Quality of Service) control policies and Billing control...
