A short message processing method and apparatus in short message interactive communication is disclosed that allocates identification codes to each service instance and performs short message interaction with uses using numbers embedded with the identification codes. In the short message processing method and apparatus of the present invention, in response to receiving of a short message from a communication terminal, a service instance for the short message is determined based on a server-side communication number contained in the short message, and then a reply short message is sent to the communication terminal using the server-side communication number that is embedded with a service instance identification code corresponding to the determined service instance. The present invention is capable of accurately and conveniently correlating a plurality of short messages with corresponding service instances, thereby enhancing users' experience during an interactive process.

Short message processing method and apparatus

A method for discovering topology in an SIP network is disclosed. According to the method, the SIP network is divided into domains governed by corresponding SIP proxies. A management system creates a topology agent for each SIP-domain and registers it with the governor proxy of each SIP-domain. Each topology agent generates topology-exploring messages to other agent and accumulates topology-exploring messages from other agents, gather routing information of the SIP network based on the collected topology-exploring messages to deduce topology of the SIP network.
