specific Embodiment approach

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 Shown is the next generation network structure diagram, figure 1 Clearly shows the hierarchical structure of the next generation network, including: service / application layer, control layer, transport layer, and access and media layer.

[0024] The service / application layer is the highest layer in the next generation network, mainly to realize some intelligent services. For example, 10086 of China Mobile, 10000 of China Telecom, or the automatic voice system of some other service companies (such as telephone banking).

[0025] The control layer is the core of the next-generation network, and its quality affects the success or failure of the entire network. The functional entity corresponding to the control layer is a soft switch (Soft Switch), which provides cal...

Abstract

The present invention relates to an access gateway and a method for utilizing DSP resources, including a resource layer and a resource management module for managing the resource layer, the resource layer includes a digital processing module DSP, and the resource management module includes a record The DSP channel capability statistical table of each channel of the digital processing module DSP being queried and occupied, the resource management module is based on the media capability value returned by the digital processing module DSP and the DSP channel capability statistical table when the call is established. The media stage provides the remaining media capabilities of the digital processing module DSP. Because the present invention records the change of DSP capability in time, there is no time difference between the inquiry of DSP capability and the actual use, thereby improving the call success rate and reducing call loss. When multiple calls are outgoing or incoming at the same time, if the high capacity is used up, the low capacity call can be used successfully.

Description

technical field [0001] The present invention relates to the application of VOIP communication technology in the next generation telecommunication network (NGN), especially to an access gateway and a method for utilizing DSP (Digital Signal Processing digital signal processor) resources, more specifically, a The invention realizes the access gateway in the next generation network and its processing method for VOIP signaling data. Background technique [0002] The next generation telecommunication network (NGN) is gradually replacing the program-controlled switching network, and the increasingly mature VOIP technology is gradually replacing the program-controlled switching technology. [0003] like figure 1 Shown is the next-generation network structure diagram. In the four-layer structure of the next-generation network, the access gateway belongs to the fourth layer, which is the equipment entity of the "access and transport layer". Its role is to connect users to the networ...
