Abstract
The method enables a set of services to be maintained within a private communications network even in the event of the network becoming split. It uses emergency means providing dynamic accesses that are previously defined by the user of the network. The dynamic accesses serve to carry signaling signals. Calls are routed using a method of routing that is both static and predetermined, imposing a path that is predetermined before a fault occurs, thereby making it possible for the network to react more quickly once it detects faulty operation.
Claims9
A method of maintaining communications options within a private communications network comprising a plurality of private exchange nodes, each of the nodes being capable of communicating with all other nodes in normal operation via two-way communications trunks interconnecting some of the nodes in pairs, the method comprising:
- detecting faulty operation that leads to the network becoming split into at least two network portions which can no longer communicate with each other via any of the trunks of the private communications network;
- implementing emergency means which provide at least one dynamic access for ensuring that all of the nodes of the network can again communicate with all of the other nodes, thereby maintaining a set of services proposed by the network in normal operation;
- transmitting calls through the network using routing that is static and predetermined once the emergency means have been implemented;
- and
- restricting signals passing between the at least two network portions once the emergency means have been implemented.
