Embodiment 1

[0060] This embodiment describes that the load sensing function collects the traffic information of each cell, and then judges the congestion state of the cell. Each user reports the latest user location information to the load sensing function through the ANDSF when accessing the network or switching over the access network. When a user starts a new service, the PCRF performs resource authorization for the service according to the congestion state of the cell used by the user. If it is congested, new services are rejected to alleviate network congestion. Such as figure 2 As shown, the process description is as follows:

[0061] 201: The load sensing function periodically collects traffic information of all cells and cell identities of corresponding cells from access network equipment (such as eNB);

[0062] 202: The load sensing function determines the congestion state of the wireless access cell accordingly;

[0063] For example, each wireless access cell reports the ce...

Embodiment 2

[0084] This embodiment describes that each user reports the latest user location information to the load sensing function through the ANDSF when accessing the network or when an access network switch occurs. When the PCRF authorizes the new service launched by the user, it requests the congestion status from the load sensing function, and the load sensing function obtains the congestion status of the cell accordingly, and returns it to the PCRF. If it is congested, new services are rejected to alleviate network congestion. Such as image 3 As shown, the process description is as follows:

[0085] 301: The user accesses the network, and establishes an IP-CAN session between the P-GW and the PCRF;

[0086] 302: The user reports the user location information and user identification to ANDSF;

[0087]The user location information is, for example, information such as a cell ID (cell id) of a cell used by the user, TAI, or GPS.

[0088] When the user initially establishes a sess...

Embodiment 3

[0100] This embodiment describes that when the load sensing function determines that the cell is congested according to the collected traffic information, it notifies the PCRF and requires the PCRF to adjust the congestion policy of the users under the cell, as Figure 4 As shown, the process description is as follows:

[0101] 401: The load sensing function periodically collects traffic information of all cells and cell identities of corresponding cells from access network devices (such as eNBs);

[0102] 402: The load sensing function determines the congestion state of the wireless access cell accordingly;

[0103] 403: the user accesses the network, and establishes an IP-CAN session between the P-GW and the PCRF;

[0104] 404: The user reports the user location information and user ID to ANDSF;

[0105] The user location information is, for example, information such as a cell ID (cell id) of a cell used by the user, TAI, or GPS.

[0106] When the user initially establish...

Abstract

The embodiments of the present invention disclose a method for controlling a network congestion and a load perception function, which are applied to a wireless communication network. The method comprises: a load perception function obtaining user location information and a user identification from an access network discovery and selection function (ANDSF) or a user equipment; and the load perception function determining a congestion state of a cell used by a user according to the user location information, the user identification and congestion judging information obtained from an access network device. In the embodiments of the present invention, the load perception function judges the congestion state of the cell used by the user according to the congestion judging information, the user location information and the user identification, so that when cell congestion occurs, a PCRF is notified to conduct congestion management on a service developed by the user in the cell, or the user equipment in the cell is notified to unload the service which is being developed, thereby alleviating the network load and reducing the network congestion.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for controlling network congestion and a load sensing function. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) defines a policy and charging control architecture (PCC, Policy and Charging Control) for mobile networks, such as figure 1 As shown, the functions of each entity are described as follows: [0003] PCRF (Policy and Charging Rules Function, policy and charging rule function) formulates resource control strategies for the use of network resources in the transmission process of business data flows included in the business, including QoS (Quality of Service, quality of service) control strategies and charging control Strategy. [0004] PCEF (Policy and Charging Enforcement Function, Policy and Charging Enforcement Function) is used to execute the PCC rules issued by the PCRF or pre-configured on the PCEF, d...
