Problems solved by technology

[0007] However, so far, the diameter protocol has not defined a practical overload control mechanism
Therefore, once an application server is overloaded, a large number of call attempts directed to the application server will fail because the application server does not have enough resources (such as CPU, memory, etc.)

example 1

[0079] refer to Figure 5 and image 3 , an example of the present invention will be described below. Figure 5 Indicates the message transfer process between the OCS and the S-CSCF based on the diameter protocol.

[0080] First, S-CSCF (Serving Call Session Control Function) sends a diameter credit control request (CCR) message to OCS (Online Charging System, an application server configured with the control device according to the present invention).

[0081] according to image 3 In the flow shown, the OCS acquires service-related information of the requested message from the received service request message. Generally, the acquired service-related information includes, but is not limited to: calling party, called party, "application ID=4" and "service content ID=32.2703gpp.org".

[0082] Based on the acquired service-related information such as the called party, the OCS judges whether the requested service is a first-type service or a second-type service. In this exam...

example 2

[0086] refer to Figure 6 and image 3 , another scenario according to a preferred example will be described below:

[0087] I.

[0088] - The S-CSCF sends a CCR message: CCR[INITIAL_REQUEST, Application ID=4, Service Content ID=32.2703gpp.org, etc.]. ]

[0089] - After receiving the CCR message from the S-CSCF, the OCS uses the service-related information obtained from the message as a key to search the pre-stored service control information. Assume that the load status of the OCS is 4, and the rules in the pre-stored service control information only include the aforementioned rules 1) to 3).

[0090] The OCS will find that the service-related information obtained from the CCR does not match any of the rules 1) to 3). Here, the requested service may be regarded as a second type of service according to a predetermined principle.

[0091] - the call will then be allowed, the control device (eg figure 2 shown) will pass the request to the charging agency to reserve the s...

Abstract

The present invention aims to provide a method and device for controlling the overload of network service equipment, so as to control the network service equipment to provide services to clients, wherein the load information of the network service equipment and the service requested by the client are considered at the same time. Related information and pre-stored service control information to determine whether the network service device is allowed to provide services to the client. Therefore, effective overload control can be performed on network service equipment.

Description

technical field [0001] The invention relates to a communication network, in particular to the overload control of network service equipment in the communication network. Background technique [0002] When unexpected events, such as floods, earthquakes, or malicious behavior of clients, occur, high call requests may occur in the communication network. During this period of high call requests, network traffic is significantly higher than predictable daily peaks, and it may exhaust resources such as memory, CPU usage, or network bandwidth of the network serving device. [0003] Accordingly, communication networks have recognized the need to provide overload control mechanisms to protect the system from excessive traffic loads. [0004] In a traditional Intelligent Network (IN), the Service Control Point (SCP) based on an application server (a service device) can apply a gapping message to the call to inform the Service Switching Point (SSP) when it is in an overloaded state. ...
