Audit method and system of carrying end

Abstract

An auditing method and system of bearer end points are disclosed in the communication field, which make MGC to quickly finish auditing lots of bearer end points in short time. An audit request message is transmitted from MGC to MGW. The audit request message asks for auditing multi-bearer end points and audit bearer end points are identified in the audit request message. When MGW receives the audit request message, it detects states of corresponding bearer end points and returns by three methods states of bearer end points which are requested audit. The first method is that an audit response message carries state of bearer end point which isrequested audit; the second method is that bitmap is added in the audit response message, and states of all bearer end points which are requested audit are carried with the bitmap to notify MGC; the third method is that states of bearer end points which are requested audit are returned to MGW by group.

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
