Problems solved by technology

[0006]Due to the great difference between R1.5 signaling, R1 signaling and R2 signaling, R1.5 signaling cannot be obtained very well in the H.248 protocol. Good mapping prevents the road-associated interface of the H.248 protocol from being directly used as the control interface of R1.5 signaling. Therefore, under the framework of separating bearer and control, the R1.5 signaling system cannot be based on the existing H.248 The channel-associated signaling interface in the protocol is realized

Embodiment Construction

[0039] The core idea of ​​the present invention is to correspond the R1.5 signaling with the signaling interface of the H.248 channel by means of reuse, multiplexing and extension, so as to achieve There is a channel-associated signaling interface in the H.248 protocol to realize the R1.5 channel-associated signaling system.

[0040] Please refer to figure 1 As shown, the structure diagram of the network device for adjusting the channel-associated signaling interface of the present invention is shown; the network device of the present invention can be a media gateway, or a media gateway controller, or a separate device. The network device includes: a receiving unit 10 , a storage unit 11 , an identifying unit 12 , an adjusting unit 13 and a sending unit 14 . in,

[0041] The receiving unit 10 is used to receive R1.5 channel-associated signaling;

[0042] The storage unit 11 stores the reused channel-associated signaling set, multiplexed channel-associated signaling set and ...

Abstract

The invention provides an adjusting method of CAS (Channel Associated Signaling) interface, which comprises: A. receiving a first CAS; B. recognizing the first CAS; C. adjusting a second CAS according to the recognizing result of procedure B; D. transferring the first CAS at the interface of the adjusted second CAS. Additionally, the invention also provides a network device for adjusting CAS interface. The invention is capable of realizing R1.5 CAS through adjusting (repeating / reusing / expanding) H.248 CAS interface, which reduces the quantity of private signaling interfaces with the simple and efficient adjusting work of signaling interface.

Description

technical field [0001] The invention relates to the technical field of channel-associated signaling interface, in particular to a method and network equipment for adjusting the channel-associated signaling interface. Background technique [0002] In the next generation network (Next Generation Network, referred to as NGN) system and the third generation network (3G) system, in order to develop a large-scale carrier-class IP telephony gateway, the gateway is decomposed into a media gateway (Media Gateway, referred to as MG) and a media gateway. A gateway controller (Media Gateway Controller, MGC for short) realizes the separation of bearer and control. [0003] In 2000, ITU-T proposed the media gateway control protocol at the 16th working group meeting, that is, the H.248 protocol, which was improved on the basis of the early media gateway control protocol (MGCP for short). , and gradually replaced the MGCP protocol, becoming the standard protocol between media gateways and ...
