Method, system and gateway for supplying intelligent service

摘要

An intelligent service system and method are provided. The method includes: receiving a calling information transmitted by a switching device through an Internet-protocol-based call control protocol and which carries the identification information of the service control function requested by the call as well as the identification information of the call; parsing the received calling information, and after the identification information of the service control function and the identification information of this calling are obtained, initiating an assist request to the service control device; receiving the resource operation instruction, and supplying service resource service accordingly; said instruction is sent out by the service control device after said device has received the assist request and according to the service requirement. The media stream leading to the media gateway is established through the media stream transport protocol based on the Internet protocol. The method simplifies the management and maintenance of the intelligent service network.

1. A method for supplying an intelligent service in an intelligent service system, comprising:
receiving, by an intelligent peripheral subsystem, Internet Protocol, IP, based call information transmitted from a switching device, wherein the call information carries service control function identification and call identification in a Session Initiation Protocol, SIP, INVITE message or in a SIP INFO message, wherein the intelligent service system comprises the switching device, the Intelligent peripheral subsystem and a service control device, and wherein the switching device, the Intelligent peripheral subsystem and the service control device in the intelligent service system communicate with each other based on the IP, and both the switching device and the Intelligent peripheral subsystem communicate with a Media Gate Way, MGW, also based on the IP; initiating, by the intelligent peripheral subsystem, an assistance request to a service control device by the service control function identification and the call identification derived from parsing of the IP based call information; receiving, by the intelligent peripheral subsystem, a resource operation instruction returned from the service control device; and supplying, by the intelligent peripheral subsystem, a service-resource service according to the resource operation instruction; wherein the initiating the assistance request to the service control device or the receiving the resource operation instruction returned from the service control device is based on an intelligent network application protocol transmitted over the signaling transport (SIGTRAN), and the switching device communicates with the service control device in an intelligent network application protocol over the signaling transport (over SIGTRAN), wherein when the IP based call information is call information based on the SIP, and wherein:
the service control function identification and the call identification is carried in a called number, a message head field or a message body in the SIP INVITE message; orthe service control function identification and the call identification is carried in a message head field or a message body in the SIP INFO message.
