Abstract

The embodiment of the invention discloses a registration method, a device and a system of a terminal. Taking the realization of the embodiment of the method as the example, the method comprises the following steps: a registration request sent by the terminal is received, and the registration request carries terminal ability information; the terminal ability information is used for judging if the terminal can use the local output service; the successful registration information is sent to the terminal; and the successful registration information includes the information about if the terminal can use the local output service. The embodiment of the invention has the following advantages that the terminal carries the self ability information in registration, a network side judges if the terminal can use the local output service and sends the judged result to the terminal, and the terminal does not need to launch the attempt of local output service, so the network resource is saved and the calling establishment time is reduced.

Description

technical field

[0001] The present invention relates to the technical field of communications, and in particular to a terminal registration method, device and system. Background technique

[0002] The Internet Protocol Multimedia Subsystem (IMS) is a subsystem superimposed on the Packet-Switched (PS) domain by The 3rd Generation Partnership Project (3GPP); IMS has a complete IP Core network functions, including session management, bearer control, etc. Its main functional entities include call session control function (CallSession Control Function, CSCF), home subscriber server (home subscriber Service, HSS), application server (Application Server, AS) and so on.

[0003] Usually, when a user roams, both the user's control signaling and bearer data need to be routed back to the home network for processing. The media needs to be transmitted between the home network and the roaming network, which causes a waste of bandwidth between networks and is not conducive to optimal tra...
