Problems solved by technology

[0010] However, this implementation scheme also brings some defects and improvements that need to be improved, that is, R2 signaling usually needs to implement TOF (Trunk Offering) long-distance operator insertion requirements, and relevant messages and information are not defined in ITU-T Q.931 unit, so the long-distance operator insertion function cannot be realized

Embodiment Construction

[0033] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0034] On the basis of the existing ITU-T Q.931, the present invention expands the message and information unit that supports TOF long-distance operator insertion requirements, thereby realizing the R2 signaling standard through R2 / PRA conversion access under the NGN framework, and A technical solution to support long-distance operator insertion. The extended ITU-T Q.931 is called the ITU-T Q.931+ protocol.

[0035] In order to realize the present invention, at first the ITU-T Q.931 agreement is extended, and concrete expansion is defined as follows:

[0036] 1. Add operator message OPR_MSG

[0037] This message can be sent to the network by the calling user (such as an operator) and then sent to the called user by the network to transmit the operation informatio...

Abstract

A method for implementing trunk offering, which is applied in NGN using Q931 protocol, the method includes: when a switch device receives a telephone call, and finds that the called terminal is busy, the switch device sends a TOF signal to a media gateway, the media gateway converts the TOF signal to a indication message of the operator, and the indication message of the operator is sent to the media gateway controller to control the call of the called terminal. The present invention also provides a system for implementing trunk offering, which includes: a switch device, for sending TOF signal to the media gateway; a media gateway, for conversion between the TOF signal and the indication message of the operator; a media gateway controller, for controlling the call according to the indication message of the operator. According to the invention, the question how to implement R2 signal standard through R2 / PRA conversion access in NGN may be resolved, and the function of the trunk offering is implemented.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a method and system for realizing toll operator insertion in NGN (next generation network). Background technique [0002] NGN network is a network in which service control and bearer media are separated. The service control part can be realized by MGC (Media Gateway Controller), and the bearer part can be realized by MGW (Media Gateway). The H.248 protocol is generally adopted between the MGC and the MGW to control the bearer. [0003] The channel-associated signaling is a kind of inter-office signaling, and the currently used channel-associated signaling includes R2, R1, and No5. Among them, R2 signaling is widely used in switch models in many countries. The R2 standards of each country generally define long-distance operator insertion signaling. In this way, when NGN system equipment enters the market of different countries and connects with switches of various models, it ...
