Distributed control method for intelligent network relay resource

Abstract

The disclosed distributed control method comprises: (1) setting different relay source servers for every area; (2) configuring servers in database; (3) downloading individual configuration informationto store locally; (4) starting calling from user; (5) querying opposite server by the business control node to send occupancy application; (6) processing the application, continuing the process or releasing. This invention improves process capacity and system security.

Description

technical field [0001] The invention relates to an intelligent network, in particular to a method for controlling call relay resources of the intelligent network. Background technique [0002] In the currently operating intelligent network system, the commonly used method of relay resource control is centralized control. Its main function is to control the amount of relay usage for each service, so as to satisfy the priority use of relays for important services to the greatest extent. And ensure that the system will not fail to call due to relay resources. Such as figure 1 As shown, the implementation steps of this method are generally: [0003] 1. User A calls user B, accesses the intelligent network service switching point SSP through the public telephone network, and enters the intelligent network system; [0004] 2. The service control point SCP of the intelligent network system applies for the use of trunk resources to the trunk resource control server according to A...

AI Technical Summary

Problems solved by technology

[0008] 1. The bottleneck problem of the trunk resource control server: In the case of a relatively large traffic volume, the trunk resource control server will have insufficient processing capacity, resulting in prolonged trunk application time and correspondingly longer call waiting time; Or the call is released due to waiting timeout, thus reducing the connection rate of the system

[0009] 2. The expansion capability of the business system is limited: because the relay resource control server adopts centralized control, the entire system only has one relay resource control server, which inevitably leads to its limited processing capacity

Therefore, in order to ensure a high connection rate of important services, the system can only sacrifice the development of users of some secondary services (because the use of its relays is limited, in order to ensure the connection rate, the total number of users has to be reduced)

[0010] 3. Single point of failure: If the relay resource control server fails to connect to the system for some reason (such as problems with the server itself, network interruption, etc.), all calls in the system will be affected, or even paralyzed. , there will inevitably be hidden dangers of major failures
