Embodiment Construction

[0051] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0052] Digital Circuit Multiplication Equipment (DCME for short) can realize digital circuit multiplication technology to achieve the purpose of concentrating a certain number of 64kbit / s PCM coded trunk channels in fewer transmission channels for transmission. Due to its characteristics, DCME equipment is generally used in the connection between international bureaus with long transmission distance and large investment in transmission channel construction. Q.50 of ITU-T defines the signaling between the international bureau and DCME equipment. its connection as figure 2 As shown, it includes international bureau 1, international bureau 2, digital circuit multiplying device 1 and digital circuit multiplying device 2, wherein Q.50 signaling is used between the international bureau and the digital circuit multiplying dev...

Abstract

The invention discloses a next generation network system supporting the digital circuit multiplication technology and the communication method, which is invented for the purpose of solving the problem existing in the prior art that the next network can not support the digital circuit multiplication technology. The device of the invention comprises a switch, a soft switch, a relay gateway and a digital circuit multiplication device. The relay gateway comprises a protocol conversion module. The method of the invention comprises the steps that: when the digital circuit multiplication device is connected to the next generation network and communicates with the soft switch through the relay gateway, the relay gateway converts the H. 248 protocol over which the soft switch communicates with the relay gateway and the Q. 50 over which the digital circuit multiplication device communicates with the relay gateway according to the requirement for transmission. Thus ensuring that the next generation network supports the digital circuit multiplication technology so as to achieve the goal of carrying out the transmission centralizing a certain number of the main line channels to which the PCM coding is applied at 64kbit / s in fewer transmission channels.

Description

technical field [0001] The invention relates to the communication field, in particular to a next-generation network system supporting digital circuit multiplication technology and a communication method thereof. Background technique [0002] The next-generation network is a network that integrates voice, data, and multimedia. It has the characteristics of separating service provision from call control, and separation of call control from bearer connections. The next generation network is divided into access layer, transport layer, control layer, and service layer from the network level. The main function of the access layer is to connect various users to the packet network, and convert the information format into an information format that can be transmitted on the packet network. It is mainly composed of relay gateways, signaling gateways, access gateways, and intelligent terminal etc. The core equipment of the control layer is the soft switch, which mainly completes func...
