Embodiment Construction

[0031] In the network architecture, the entities in the system need resources to process the received request / response messages, and the system overload often refers to the situation that the current resources cannot or are not enough to process the received request or response messages; when Overload also occurs in a SIP network when functional entities in the SIP network cannot process SIP requests or responses.

[0032] There are two main types of overload: one is server overload, which is overloaded because the server cannot process the messages it receives, or is unable to receive messages because the server is busy with other processing processes, resulting in overload; the other is network overload, which is caused by insufficient network bandwidth , cannot process messages, for example, if the network bandwidth is 256Kbps, but actually needs 2Mbps, then a large number of information packets will be discarded in the network, which is similar to the SIP messages in the SI...

Abstract

The invention relates to a method, a system and an SIP entity for overload processing. The overload processing method comprises the following steps that: a requesting party sends a request message carrying a load head to a receiving party by or not by a middle entity; and the middle entity and / or the receiving party can feed a response message carrying the load head back to the requesting party byanalyzing the requested load head, so that the requesting party can determine the overloaded entity by analyzing and computing the load head and reduce request messages to be sent. The system comprises the SIP entity of the requesting party and the SIP entity of the receiving party. The method, the system and the SIP entity for overload processing indicate the overloaded entity and the sending quantity of the messages to be reduced by adding load heads in the request message and the response message, realizes the effective overload detection without increasing system load, and is flexible, simple and effective in overload detection.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an overload processing method and system, and a SIP entity for overload processing. Background technique [0002] In a communication network, overload control is one of the important call processing control mechanisms, especially in a Next Generation Network (NGN) where a single server handles nationwide call services. In services where Session Initiation Protocol (Session Initiation Protocol, SIP for short) is an interactive protocol, overload detection and processing only exist in the application layer. [0003] One of the more overlooked aspects of overload control is overload detection. Overload detection is generally based on the use of system resources. In addition to CPU resources, system resources also include memory resources, file handles, disk IO, etc., but CPU is generally used as an overload condition for detection. The occupancy of system resources ca...
