Example Embodiment

[0022] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0023] In the IP network, the task of providing value-added services to end users is done by SPD. However, the SPD is mainly responsible for providing business logic, and it is impossible to provide services to the majority of IP network users (especially the majority of PSTN users using the IP network) by relying on it alone. SPD must carry out intercommunication and cooperation with NCD, and through NCD control of various user terminals in the lower layer, can it finally complete the purpose of providing services to users of IP networks in a broad sense.

[0024] The present invention provides a method for NCD and SPD to communicate with each other in the process of providing services to IP network users, that is, by designing a message format to extend the standard SIP protocol "BODY" part to complete a complete Business call process.

[0025] Table 1 is ...

Abstract

This invention discloses a method for intercommunicating between a control device and a service device to provide service including: a user terminal, an access device, NCD and this side SIPX information analyzer, information form expanding of the SIP protocol BODY part, concrete image relationship between the service and SIPX information. This invention utilizes the character of being the session protocol on IP network to expand the standard SIP protocol and add some suitable information forms to make up for fixed shortcomings of SIP.

Description

technical field [0001] The invention belongs to a data communication network, in particular to an IP (Internet Protocol) network. Background technique [0002] For the traditional Public Switch Telcom Network (PSTN), the provision of value-added services mainly depends on the "intelligent network", that is, on the service control point (Service Control Point, SCP), service switching point (Service Switch Point, SSP) , the service management point (Service Managment Point, SMP) and other intelligent node devices work together, and the core is the Intelligent Network Application Protocol (Intelligent Network Application Protocol, INAP) message interaction between the SCP and the SSP, to complete the provision to PSTN users Various value-added services; [0003] With the emergence of IP network and its rapid development, how to provide IP network users with value-added services—and more diverse services—has gradually become a big topic in front of relevant researchers. . As ...
