Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 It is a flowchart of an exemplary method for implementing overload control in a packet network according to an embodiment of the present invention.

[0032] Such as figure 1 As shown, the method includes:

[0033] Step 101: Set service request routing conditions.

[0034] Wherein, the embodiment of the present invention can set service request routing conditions in the client. In the embodiment of the present invention, the service request routing condition can also be set on the server, and then the server sends the service request routing condition to the client by carrying the service request routing condition in the overload indication information.

[0035] The server may actively send overload indication infor...

Abstract

The invention discloses a method for realizing overload control in a packet based network, which comprises the steps that: when a server is over loaded, a client end judges whether a current service request received meets preset service request routing conditions or not; if the current service request received meets the preset service request routing conditions, the client end routes the current service request to the server. The invention also discloses a system and a device for realizing overload control in the packet based network. The application of the invention does not means carrying out respective process according to the characteristics of the request instead of not transmitting any request to an overload server simply, thereby promoting the usability of the packet based network. Besides, the invention also ensures that session of urgency priority can be carried out.

Description

technical field [0001] The present invention relates to the technical field of next generation network (NGN), and more specifically, the present invention relates to a method, system and device for realizing overload control in a packet network. Background technique [0002] With the continuous maturity of packet technology, the traditional telecommunication network based on circuit switching is developing into a broadband telecommunication network based on packet switching, and the use of Session Initiation Protocol (Session Initiation Protocol, SIP) as the call control signaling of the core network of packet telecommunication is currently One of the technological development trends. For example, in the research process of the next generation network (Next Generation Network, NGN) by standard organizations such as the International Telecommunication Union (ITU-T) and the European Telecommunications Standards Institute (ETSI), the third-generation partners are adopted. The ...
