摘要:
A method of TCP, UDP or SCTP communication between two railway signalling entities (6, 18) over a wireless network (3), comprising: configuring first and second MCData clients (15, 21) for the signalling entities (6, 18) and registering the first and second MCData clients (15, 21) with an MCData server (14) of the wireless network (3) for MCData SDS transfer according to a 3GPP LTE standard; receiving a signalling message (19) according to a TCP, UDP or SCTP standard from the first signalling entity (6) in the first MCData client (15); in the first MCData client (15), wrapping the signalling message (19) in an MCData SDS message (22); sending the MCData SDS message (22) from the first MCData client (15) to the second MCData client (21) via the MCData server (14); extracting the signalling message (19) from the MCData SDS message (22) in the second MCData client (21); and sending the signalling message (19) to the second signalling entity (18).
摘要:
The invention relates to a device for signaling a caller identification (A), transmitted in a telephone network (PSTN) to a telephone set (2), to a remote location (3). The telephone network is provided with service intelligent unit (IN) and the remote location (3) is provided with an internet terminal (4) with an internet address (URL). The switching center (VB) is provided with an intelligent network hook (5) which transmits the caller identification (A) together with an identification (B) of the telephone set (2) to a service (SF) of the service intelligent unit (IN), and said service intelligent unit (IN) has an interface (7) to the internet (IP). An internet proxy (PXY) administers a database (DB) in which the telephone set identifications (B) can be input with their associated internet addresses (URL). The service (SF) transmits the caller identification (A) and the telephone set identification (B) via the interface (7) to the internet proxy (PXY). Said internet proxy (PXY) looks up the associated internet address (URL) in the database (DB) and transmits the caller identification (A) to the internet address (URL).
