Problems solved by technology
In the current power system, a large number of soft switches are distributed in different physical locations, there are no maintenance personnel on site, and backup operations must be performed before daily operation and maintenance, upgrades, and operations, which makes the work of the power information interaction system developed today change. very cumbersome
[0004] At the same time, although the system provided by the softswitch equipment manufacturer also has the function of instant access, it adopts a single-process method, and the corresponding terminal cannot be used for other operations when, for example, backing up data. For complex network elements, it will take up The terminal takes a long time, which also affects the daily maintenance work

The invention discloses a softswitch-based power dispatching system, which includes a softswitch layer, an access terminal and a data bearer network, wherein call control and media gateway access control are performed through the softswitch layer, and the data bearer network is used as an access The signal or signaling flow channel between the ingress terminal and the softswitch layer. The system of the present invention can effectively solve the maintenance cost and efficiency problems of the current electric power dispatching system, especially can simultaneously realize the compatible access of multiple access terminals during the voice service connection process, and realize efficient data exchange of electric power information. On the other hand, it can structurally ensure that each softswitch system call is stable and safe, ensuring the accuracy of voice traffic information transmission.
Description
technical field [0001] The present invention relates to power system information scheduling technology, more specifically, relates to an information interaction technology and interaction method realized based on a soft switch system. Background technique [0002] Softswitch technology has increasingly affected the development direction of telecommunication networks and interactive protocols. With the continuous maturity of softswitch technology, the cost of telecommunication operations has been greatly reduced, and network transformation has been successfully realized. For example, The traditional voice service and some data services are shunted through the soft switch, and the replacement of the second technology and equipment update is finally realized. [0003] High integration is a major advantage of softswitch technology. The large system capacity and access capability greatly reduce equipment nodes and simplify the network. The system program and office data of the so...
