Method for controlling servers
View Patent ↗There may be applications where for IN-calls, one SCP begins processing a transaction for supporting a service but another SCP continues processing said transaction. The invention shows how such a continuation of processing can be carried out in cases where this can be solved in terms of protocol.
1. A method for controlling services in a communications network, comprising:
communicating with a first server initiated by a network node in the communications network to assist processing of a service;
ending the communication by the first server when the first server and the network node have gathered information which is required for selection of a second server, the second server assisting in processing of the service, and which can be transmitted by using a single message to one of the servers; and
instructing the network node to start a second communication with the first server to assist the processing of the service, with the information required for selection of the second server packed into the first message in the second communication, wherein
the first message is processed by the first server, and information relating to acceptance of the second communication is passed to the second server, and
the second communication is continued by the second server.
2. The method as claimed in claim 1 , wherein when the first communication is ended by the first server, additional information is passed to the network node and is mirrored in the second communication to the first server.
3. The method as claimed in claim 1 , wherein when the first communication is ended by the first server, information is passed to the network node, and the second communication is set up directly to the second server.
4. The method as claimed in claim 1 , wherein the communication between the network nodes and the servers is carried out using an INAP protocol.
5. The method as claimed in claim 2 , wherein when the first communication is ended by the first server, information is passed to the network node, and the second communication is set up directly to the second server.
6. The method as claimed in claim 2 , wherein the communication between the network nodes and the servers is carried out using an INAP protocol.
7. The method as claimed in claim 3 , wherein the communication between the network nodes and the servers is carried out using an INAP protocol.
