Embodiment Construction

[0028] The basic idea of ​​the present invention is: by carrying the relevant parameters of the signal list, the amount of information sent by the SERVER to the MGW message is simplified, and the overhead of transmission and information encoding and decoding is reduced. The present invention has two implementation modes: 1. Add parameters to the signal list, which is subsequently called mode 1; 2. Add parameters of the control signal list in the ITU-T H.248 packet (Packet) definition, which is subsequently referred to as mode 2.

[0029] For method 1, add parameters to the signal list. According to the definition of the signal list, add parameters such as "number of cycles", "notification direction", "notification variable (language, voice)", and "completion notification" to the signal list .

[0030] For the second method, add parameters for controlling the signal list in the newly added package or the existing playback package, including "signal list ID", "number of cycles",...

Abstract

The invention discloses a voice signal display method, comprising the steps as following: a media gateway controller sends display request information to a media gateway, wherein the display request information carries a signal list composed of a voice signal need to display and control parameter information for controlling display of the signal list; the media gateway displays all voice signals in the signal list according to the control parameter information. For playback requests such as looping and multi-language display with consistent grammar, the invention accomplishes by simplifying present playback, which accomplishes service voice display operation conveniently and rapidly.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a sound signal playing method. Background technique [0002] The network architecture that separates bearer and control is the current development trend of mobile communication networks. Its application scope includes 3GPP R4 and later versions, IMS, and next-generation networks (NGN), etc. The entity that implements the control function is the Media Gateway Controller (Media Gateway Controller , referred to as MGC, hereinafter referred to as SERVER), and the entity implementing the bearer function is a media gateway (Media GateWay, referred to as MGW). The SERVER completes the call-related control functions, and the MGW completes the bearer-related control functions and media transmission functions. The relationship between them is as follows: figure 1 As shown, the SERVER receives services from the Radio Network Controller (RNC for short) / Base Station Controll...
