Embodiment Construction

[0068] The present invention will be further elaborated below in conjunction with accompanying drawing and specific embodiment:

[0069] FIG. 2 is a system architecture diagram of the SIMULATION service provided by the IMS network to CS domain terminals. As shown in the figure, a traditional circuit domain terminal accesses an IMS network through a signaling access adaptation entity. Traditional circuit domain terminals include PSTN and ISDN terminals; IMS network includes interconnected IMS core network and IMS application server; IMS core network is the IMS core network defined by standard organizations such as 3GPP or TISPAN or ITU-T, and IMS application server is 3GPP The IMS application server defined by standard organizations such as , TISPAN, and ITU-T is connected to the I / S-CSCF (Inquiry / Service Call Session Control Function) through the ISC interface to provide the control function of the IMS SIMULATION application service.

[0070] The signaling access adaptation e...

Abstract

A method for realizing packet service in circuit domain terminal access packet network includes receiving input information of user network interface by signaling access adaptive entity to carry out conversion from PSTN/ISDN service logic to analog service logic and converting conversion to be SIP terminal service operation process in analog service, making IMB network access circuit domain terminal provide packet service for said process by converting analog service logic to be PSTN/ISDN service logic and by sending user network protocol information to user terminal. The system used for realizing said method is also disclosed.

Description

[technical field] [0001] The present invention relates to the field of communication technology, in particular to a system and method for a circuit domain terminal to access a packet network to realize a packet service. [Background technique] [0002] IMS (IP Multimedia Subsystem, IP Multimedia Core Network Subsystem), as a network based on packet switching, is a subsystem supporting IP multimedia services proposed by 3GPP (3rd Generation Partnership Project) in Release 5. Its core feature is the use of the SIP protocol (Session Initiation Protocol) and its independence from access. IMS is a multimedia control / call control platform in the packet domain, supports session and non-session multimedia services, and provides a common service platform for future multimedia applications. Under the development trend of network convergence, many international and domestic organizations are researching IMS-based network convergence solutions. The NGN basic architecture of IMS mainly ...
