Audit method and system of carrying end

Abstract

The invention relates to communication field, it discloses an audit method of loading end and system the MGC can accomplish audit of large quantity of loading ends. In the invention, MGC sends an audit request message to MGW for loading ends, and the loading ends are marked in the request message. MGW receives the audit request message, and detects corresponding ends, and state of loading ends is returned to MGC in three modes; the first mode is an audit response message takes a state of loading end of request; the second mode is an audit response message possesses bit bitmap which can take state of loading end to MGC; the third mode is state of loading end is returned to MGW.

Description

technical field [0001] The invention relates to the field of communication, in particular to the audit technology of bearer endpoints. Background technique [0002] In the field of communications, traditional voice services are usually provided by the Public Switched Telephone Network ("PSTN"). PSTN is a circuit-switched network, which brings a lot of inconvenience to users, such as high communication prices, slow Internet speed, The waiting time is long, the transmission quality is low, and it is difficult to add new services. With the development of communication technology and the rapid growth of data services, it is gradually becoming possible to carry services such as voice and data on a single data network. [0003] The Next Generation Network ("NGN" for short) is proposed under such circumstances, and has developed rapidly in recent years. [0004] NGN adopts SoftSwitch technology that separates call control and bearer media. The processing capability of network equ...

Problems solved by technology

[0007] In practical applications, the above solution has the following problems: the existing audit method takes a lot of time when there are too many endpoints to be audited, so that the state consistency of the bearer endpoints on the MGW and MGC cannot be guaranteed for a long period of time

[0008] The main reason for this situation is that in the existing audit method, the audit of each bearer endpoint needs to be requested and fed back separately. In a network with high complexity and large capacity, due to the large number of users, each MGC It is necessary to control a large number of bearers. The MGC needs to send a large number of audit request messages to audit each bearer endpoint. Similarly, the MGW needs to perform status detection according to the request. This increases the time required to complete all bearer audits, and may easily cause inconsistencies in the states of the bearer endpoints on the MGW and MGC for a long period of time

Moreover, a large number of sending and receiving and processing messages has a great impact on the processing capabilities of MGC and MGW, which may easily lead to a decline in the ability of MGC and MGW to process other services
