Embodiment 1

[0099] This embodiment describes that after the user establishes an IP-CAN (IP-Connectivity Access Network, IP connection access network) session, after the UE initiates service access, the PCRF makes a policy decision. The IP-CAN session established by the UE does not have a BBERF. Specific process such as Figure 4 shown, including the following steps:

[0100] Step 401: During the UE's request to establish an IP-CAN session, the PCEF receives a request to establish an IP-CAN session message, which carries the user ID of the user and the PDN ID of the PDN network requesting access. In this embodiment , at this time, the PCEF will receive an indication that the wireless base station currently accessed by the UE supports ECN from the lower network element (such as the S-GW in the EPS system or the SGSN in the UMTS system, etc.);

[0101] Among them, in the EPS system, the specific process of the PCEF receiving the indication from the lower layer network element that the wire...

Embodiment 2

[0122] This embodiment describes that after the user establishes an IP-CAN session, the UE initiates service access, and the PCRF makes a policy decision. The IP-CAN session established by the UE has a BBERF. Specific process such as Figure 5 shown, including the following steps:

[0123]Step 501: In the process of the UE requesting to establish an IP-CAN session, the gateway where the BBERF resides receives a request to establish an IP-CAN session message, and the message carries the user ID of the user and the PDN ID of the PDN network requesting access. At this time, BBERF receives an indication that the UE's current wireless base station supports ECN from the lower network element (such as the S-GW in the EPS system, etc.);

[0124] Among them, in the EPS system, the specific process of BBERF receiving the indication that the UE's current wireless base station supports ECN from the lower layer network element is as follows:

[0125] In the attach process of the UE, the...

Embodiment 3

[0147] This embodiment describes the flow of PCRF update policy caused by UE establishing an IP-CAN session and accessing services as in Embodiment 1 or Embodiment 2, and switching to a wireless base station that does not support ECN due to UE movement. The IP-CAN session of the UE does not have a BBERF. Specific process such as Figure 6 shown, including the following steps:

[0148] Step 601: The UE accesses another wireless base station due to movement. During this process, the PCEF receives a request to modify the IP-CAN session message, which carries an indication that the wireless base station does not support ECN. The GW or the SGSN in the UMTS system, etc.) receives an indication that the wireless base station currently accessed by the UE does not support ECN;

[0149] Among them, in the EPS system, the specific process of PCEF receiving the indication of whether the wireless base station accessed by the UE supports ECN from the lower layer network element is as fol...

Abstract

The invention provides a policy and charging control (PCC) method and a system based on the network load. The method comprises the following steps: when a policy and charging rule function (PCRF) makes a policy decision, according to whether a wireless base station accessed currently to a user equipment (UE) supports an explicit congestion notification (ECN) and the UE and the correspondent node of the UE support the ECN, the Maximum BitRate (MBR) in the Quality of Service (QoS) information of the policy is set to be greater than a Guarantee BitRate (GBR), or the MBR in the QoS information of the policy is set to be equal to the GBR; the PCRF sends the policy to a policy implementation function, and the policy implementation function implements the policy. The invention also provides a PCC system based on the network load.

Description

technical field [0001] The invention relates to the communication field, in particular to a network load-based policy charging control method and system. Background technique [0002] Since the 3rd Generation Partnership Project Phase 7 (3GPP Release7) standard system, policy and charging functions are implemented by a policy and charging control (PCC, Policy and Charging Control) framework. The PCC architecture is a functional framework that can be applied to multiple access technologies. For example, the PCC architecture can be applied to the Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System). ), Global System for Mobile Communication (GSM, Global system for Mobile Communication) / GSM Data Enhanced Evolution (EDGE) wireless access network, Interworking Wireless Local Area Network (I-WLAN), and Evolved Packet System (EPS, Evolved Packet System), e...
