Problems solved by technology

As the number of softswitch access terminals increases, the number of AGs processed in parallel also increases, but the access control in each AG only serves the device itself, which is a waste of hardware
In addition, it also brings many management limitations: when upgrading the equipment, all AGs under the softswitch must be upgraded individually, which wastes a lot of manpower and material resources; it is not easy to achieve redundant backup of multiple AGs; softswitch equipment It is necessary to configure and manage multiple AGs; control and voice are not really separated; failures cannot be located, etc.
In short, as the number of access terminals increases, it is difficult for the existing AG to support large-scale applications at the carrier level

Embodiment Construction

[0088] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0089] 1. Control Subsystem 1

[0090] (1) Main functions of control subsystem 1

[0091] 1. Respond to the command issued by the softswitch device 0, and send corresponding control instructions to the call subsystem 2 according to the command of the softswitch device 0;

[0092] 2. Respond to the access request event of the call subsystem 2, and report to the softswitch device 0 in time.

[0093] (2) Main control module 1.1

[0094] As shown in Figure 4, the main control module 1.1 includes a core control module 1.1.1, a board adapter module 1.1.2, a protocol adapter module 1.1.3, a network management module 1.1.4, and a network access module 1.1.5, which are divided into upper layers , middle and bottom

[0095] 1. The upper layer is the core control module 1.1.1, which manages all business modules in the call subsystem 2, and all control commands in the call subsystem 2 are sent b...

Abstract

The invention relates to a large integrated access network gate based on NGN. Wherein, said invention comprises soft exchanger (0), control subsystem (1), call subsystem (2), user terminal (3), ascending IP support network (4.1), and descending IP support network (4.2); the ascending of control system (1) via IP support network (4.1) is connected to soft exchanger (0) via H.323, MGCP, H.248, or SIP; the descending of control subsystem (1) via descending IP support network (4.2) uses self-defined control manage protocol to communicate with call subsystem (2); the call subsystem (2) via twisted line accesses into user terminal. With said invention, when upgrading and abundant backup, system only needs to operate control subsystem, with low cost and simple management.

Description

technical field [0001] The invention relates to an access gateway system, in particular to a large-scale integrated access gateway system based on NGN. Background technique [0002] Integrated access is an inevitable requirement for economical network construction, diverse user service needs, and network evolution and integration. With more and more types of services, it is obviously uneconomical and unreasonable to use separate access methods for different services, and it is also difficult to quickly meet the comprehensive needs of users for multiple services such as voice, data, and video. In general, integrated access has the following advantages: reducing network construction costs, reducing operation and maintenance costs, optimizing and simplifying network structure, quickly providing services and providing users with "one-stop" full-service access services, which is the core of NGN. An important part of. [0003] In a narrow sense, NGN (Next Generation Network, nex...
