However, for one-to-many operations, that is, there is only one device but the registration process of multiple users. For example, in an office fixed-line network, different fixed-line phones need to make temporary calls at different times. The existing IMS access process no such function

Embodiment Construction

[0047] Below we discuss various embodiments of the present invention in detail, Figure 1B The basic frame structure diagram of the IMS system provided by the present invention. A general IMS architecture includes three layers: transfer layer, network layer, and application layer. The registration manager proposed by the present invention is in the application layer, and the general framework includes two terminals 152 and 153 registered with P-CSCF (150A 150B). P-CSCF represents the function of the proxy call control stage, which can be used as a SIP server or proxy to generate signals in the IMS system. Therefore, the two SIP proxies 150A and 150B are the first communication nodes between the IMS system and the user terminal. As a proxy server, the P-CSCF can be deployed on the public network, or it can also be deployed on the home network when the public network cannot be accessed. The user terminal is connected to the P-CSCF through the Dynamic Host Assignment Protocol ...

Abstract

The invention discloses a registration method and device for an IMS system. The device comprises user equipment UE, a sending unit, a receiving unit, an authentication unit and a registration unit. The method is different from an original IMS registration method. According to the method, when a registration event occurs, a network device needs an access certificate for each user, so the pressure of a server can be mitigated. The certificates are produced by one interface which is not displayed in the network device or an image. When a self-defined condition is satisfied, the network device generates a notice to an enabler, and the enabler sends the notice to the users. Due to connection with P-CSCF, S-CSCF and HSS, the invented network device looks more like a user. The network device is connected with the P-CSCF through an interface Gm, and through utilization of an SIP protocol in the interface, information can be transmitted between the user equipment and a session control function server.

Description

technical field [0001] The invention belongs to the technical field of IP multimedia subsystems, and in particular relates to a registration method and device of an IMS system. Background technique [0002] IMS (IP Multimedia Subsystem) is a fusion of multiple cellular network technologies that enables people anywhere to conduct instant messaging, participate in video conferences, and send e-mails. IMS is a core element of the third generation network framework, which can provide most Internet services. For example, it enables a person to use any terminal device to log in his favorite web pages, read emails, watch movies or participate in video conferences. [0003] With the integration of packet switching technology and circuit switching technology becoming the trend, the main goal of IMS is to use this technology to connect mobile devices to the Internet. Its other goal is to create a platform that can provide a variety of multimedia services and expand the service range...
