Abstract: A system, device and method for implementing a special call service are disclosed. The method includes receiving a session establishment request message carrying a service type identifier, determining a service type identified by the service type identifier in the session establishment request message, and implementing a special call service with a service processing logic corresponding to the service type.

Abstract: A method for processing a short message and a communication terminal are disclosed. The method includes: receiving a short message; extracting schedule information from the short message after determining that the short message is a schedule short message; and importing the schedule information into a schedule table. The inventive solution enables the communication terminal to automatically identify the schedule short message upon receipt of the short message and imports such schedule short message into the schedule table without manually operating by the user, thereby improving the user experience and increasing the inner value of the communication device.

Abstract: A communication method, device and system for implementing a scheduling communication service are provided. The communication system includes: a switch, a scheduling application server, and a scheduling terminal, the switch transfers a request message or a response message with a scheduling terminal as a caller or a callee to the scheduling application server, the scheduling application server stores session parameters of the scheduling terminal, determines the type of the call request message, converts the request message into one or more common call requests or response messages that can be identified by the switch, and sends the converted messages to the switch.
