Abstract

A method and system for routings are disclosed. The method includes: receiving a SIP request message that carries semantic information of a service; by using the semantic information carried in the SIP request message as an input, searching for the service through semantic inference; generating a standard service request message which carries found service information, and sending the message to an application server that handles the service. The present invention increases the quantity of services available for requesting, and improves the flexibility of requesting services.
