Abstract: A method and a system for automated switchover timer's tuning on network systems or Next Generation Emergency Systems configured so that the sending, by a master node, of a heartbeat and/or ARP ping to one or more backup nodes and/or a surveillance unit according to preconfigured switchover timer values can occur to check if the master node is still active. One or more backup nodes and/or a surveillance unit, can use an additional first Session Initiation Protocol (SIP) OPTION message to the master node after receiving the heartbeat and/or the ARP ping or if the heartbeat and/or ARP ping fails to be received according to the switchover timer values. An administrator or an administrative unit of the network can perform a switchover or failover to a backup node in case the first SIP OPTION message is not answered with a suitable response by the master node.

Abstract: A method of processing an emergency call in an emergency communication network can include receiving an emergency call from an emergency caller from a first mobile communication device that is received via a SIP INVITE message; obtaining location information of the location of the first mobile communication device; determining a PSAP that is in the vicinity of the location of the first mobile communication device, and forwarding the emergency call to the PSAP for being handled by a call taker at the PSAP. The ESRP can request location information of all mobile communication devices that are in the vicinity of the first mobile communication device and, upon receipt of the location information, create a list of all mobile communication devices that are in the vicinity of the first mobile communication device for transmitting the list to the PSAP to be displayed at a display device of a call taker.

Abstract: A method of providing backup for an OpenScapeVoice (OSV) register configuration, with at least one OpenScapeBranch (OSB), the at least one OSB providing communications to Session Initiation Protocol (SIP) subscribers, and communicating on a main routing path, via a main Session Boarder Controller (SBC) configuration with an OSV server based on SIP, the OSB maintaining a database in which SIP subscribers currently communicating are registered. The method can include: copying the database to a redundancy SBC configuration on the basis of the SIP protocol, establishing an alternative routing path for communication of the OSB via the redundancy SBC to the OSV server, continuing the providing of the communications of the SIP subscribers via the redundancy SBC configuration. The method can be utilized in a system for providing backup for an OSV register configuration, a non-transitory computer readable medium, and a terminal device.
