Telecommunications Routing System

摘要

In Internet Protocol communications based on mobile station number (MSISDN) such as Rich Communication Services (RCS), the operator in a region which should be used to route services to a user device addressed by a mobile station number can be determined by recording which operator is the source of any capabilities exchange or signed presence subscription messages relating to the mobile station number which are received. The identified operator identities can then be stored in association with the respective mobile station numbers in a routing database. Messages to be sent to mobile station numbers can then be routed based on respective stored operator identities associated with the mobile station numbers in the routing database.

1. A method of automatically gathering routing information in a telecommunications network providing Internet Protocol “IP” communications based on mobile station number “MSISDN”, the method comprising the steps of:
analyzing incoming telecommunications traffic to identify messages from other telecommunications networks, which messages include mobile station numbers; and, when such a message is identified: extracting the mobile station number from the identified message; obtaining routing data for the telecommunications network from which the message was received; and storing the extracted mobile station number in association with the obtained routing data.
