Patent ID: 10873981

Abstract:
In a telecommunication system comprising multiple switching nodes (10, 20, 30) having a respective local server (C1, C2, C3) and associated terminals (D1, D2, D3, D4) located within a network and a central DSS server (DSS) for controlling the telecommunication system by using a general switching protocol, the terminals (D1, D2, D3, D4) of a switching node (10, 20, 30) are controlled by the local server (C1, C2, C3) under a local protocol comprising control commands for node-internal call pickup. The pickup of a call directed from a third terminal (D4) to a first terminal (D3) assigned to a first switching node (10) through a second terminal (D1) assigned to another, second switching node (20) occurs across nodes by using the general switching protocol through transferring the control commands provided in the local protocol for call pickup to the general switching protocol and providing them across nodes through the central DSS server (DSS) to the multiple switching nodes (10, 20, 30) located within the network, and converting the registration of a terminal (D1, D2, D3, D4) for call pickup provided in the local protocol to the general switching protocol and forwarding it to the central DSS server.
