Problems solved by technology

However, because the development of SIP itself is not perfect enough, some important problems in the intercommunication between NCD and SPD cannot be solved by using SIP. Therefore, using pure SIP as an interworking protocol is not a successful solution.

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

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

[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 expand the standard SIP protocol "BODY" part to complete a complete Business call process.

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 ...
