ROUTING OF SHORT MESSAGES IN A TELECOMMUNICATION SYSTEM

摘要

The invention relates to a method and a system for transmitting short messages between mobile communication systems. The system comprises a first and a second mobile communication system (MSN1 and MSN2) which are based on different mobile communications standards and combined by a gateway (GW). The mobile communication systems (MSN1 and MSN2) comprise short message service centres (SMSC1 and SMSC2). The second mobile communication system is connected to a home location register (HLR) and a mobile services switching centre (MSC). In the method, the routing component is used to make the routing data inquiries addressed to a predetermined numerical space to the gateway (GW), and the short message is transmitted based on the address received in response to the aforementioned routing data inquiry to the gateway to be transmitted further to the second mobile communication system.
