Abstract
A relay server 31 includes: a detection unit 31A that detects a failure of a subscriber server 21; and a relay unit 31B that relays call connection requests 51, 52, and 53 to another network in which corresponding subscribers may possibly be accommodated according to connection attempt network information indicating networks to attempt a call connection, when a failure of the subscriber server 21 is detected by the detection unit 31A.
Claims9
A relay server comprising:
- a detection unit, including one or more processors, configured to detect a failure of a subscriber server;
- a relay unit, including one or more processors, configured to relay a call connection request to another network in which a corresponding subscriber may be accommodated according to connection attempt network information indicating a network to attempt a call connection, when a failure of the subscriber server is detected by the detection unit;
- and
- a guidance unit, including one or more processors, configured to provide to a caller terminal, a guidance indicating that there is a failure being occurred, when a response indicating that no corresponding subscriber is accommodated is returned from another server to which the call connection request is relayed.
A relay method executing, performed by a relay server, the relay method comprising:
- detecting a failure of a subscriber server;
- relaying a call connection request to another network in which a corresponding subscriber may be accommodated according to connection attempt network information indicating a network to attempt a call connection, when a failure of the subscriber server is detected;
- and
- providing to a caller terminal, a guidance indicating that there is a failure being occurred, when a response indicating that no corresponding subscriber is accommodated is returned from another server to which the call connection request is relayed.
A non-transitory computer readable medium storing one or more instructions causing a computer to execute:
- detecting a failure of a subscriber server;
- relaying a call connection request to another network in which a corresponding subscriber may be accommodated according to connection attempt network information indicating a network to attempt a call connection, when a failure of the subscriber server is detected;
- and
- providing to a caller terminal, a guidance indicating that there is a failure being occurred, when a response indicating that no corresponding subscriber is accommodated is returned from another server to which the call connection request is relayed.
