ABSTRACT:
An instant messaging (IM) system and a method for communicating instant messages between an IM server11and a remote communication network utilising a sequential message handshaking protocol across a computer network that is prone to latency and instability. The remote communication network is a GSM network16having “Short Message Service” (SMS) for subscribers with mobile GSM devices18linked to a “Short Message Server Center” (SMSC) for sending and receiving instant messages remotely of the GSM network16and as part of the IM system. The SMSC is provided with an SMSC server15connected by a highly stable link19with low latency to an SMSC buffer server14forming part of the computer network. The SMSC buffer server14is connected to the IM server11via the internet13to complete the computer network. The SMSC buffer server14provides for sequential message handshaking that requires and provides a confirmation of receipt of message from the SMSC server15, and is provided with a buffer to facilitate storage of received instant messages received from the SMSC server15. Delays are mitigated in the communication of instant messages between the SMSC server15and the SMSC buffer server14, regardless of latency and instability associated with the internet. The SMSC buffer server14is also provided with a protocol that doesn't rely upon sequential confirmation of message transfer for communicating messages rapidly via the internet with the IM server, thereby accommodating latency and stability problems associated with the internet.
