Embodiment 1

[0070] Such as figure 2 As shown, it is a schematic flow chart of the registration method of the IMS terminal in Embodiment 1 of the present invention, and the registration method of the IMS terminal includes the following steps:

[0071] Step 201: The IMS terminal sends a registration request message to the corresponding S-CSCF.

[0072] Specifically, before the IMS terminal initiates a registration request message to the corresponding S-CSCF in step 201, the following steps need to be performed:

[0073] Similar to the registration process of the IMS terminal in the prior art, the IMS terminal needs to initiate a registration request message to the P-CSCF, I-CSCF, etc. in the IMS network, that is, the IMS terminal needs to go through figure 1 Step 101 to step 114 and other registration procedures.

[0074] Specifically, the registration request message initiated by the IMS terminal may include information such as the terminal identifier.

[0075] Specifically, the reason...

Embodiment 2

[0083] Such as Figure 4 As shown, it is a schematic flowchart of the IMS terminal registration method in Embodiment 2 of the present invention, and the method in Embodiment 2 is a detailed description of the method in Embodiment 1.

[0084] The registration method of the IMS terminal in the second embodiment includes the following steps:

[0085] Step 401: The IMS terminal sends a registration request message to the corresponding S-CSCF.

[0086] Specifically, the operation content of this step 401 is the same as that of step 201.

[0087] Step 402: After receiving the registration request message initiated by the IMS terminal, the S-CSCF judges whether the data information of the IMS terminal corresponding to the terminal identifier has been stored locally according to the terminal identifier carried in the registration request message.

[0088] If the judgment result is yes, go to step 403 ; otherwise, go to step 405 .

[0089] Step 403: The S-CSCF reads the locally stor...

Embodiment 3

[0097] Such as Figure 5 As shown, it is a schematic flow chart of the logout method of the IMS terminal in Embodiment 3 of the present invention, and the logout method includes the following steps:

[0098] Step 501: The IMS terminal sends a deregistration request message to the S-CSCF.

[0099] Specifically, the IMS terminal may initiate the deregistration request message due to its own reasons, or may be caused by sudden network failures, such as network upgrades or network element restarts.

[0100] Specifically, the process for the IMS terminal to initiate the logout request message may be the same as the process for the IMS terminal to initiate the logout request message in the prior art.

[0101] The IMS terminal may register in the S-CSCF according to the method in Embodiment 1 or Embodiment 2 before initiating a deregistration request message.

[0102] Step 502: After receiving the logout request message initiated by the IMS terminal, the S-CSCF determines the data ...

Abstract

The invention discloses a registration method, a device and a system of an internet protocol multimedia subsystem (IMS) terminal. A storage function of service-call session control functional entity (S-CSCF) is added for data information of the IMS terminal, when a registration request is launched in the IMS terminal and the S-CSCF judges that the data information of the IMS terminal is stored locally, the S-CSCF carries out a registration operation of the IMS terminal using the data information, namely the S-CSCF does not need to request and obtain the data information of the IMS terminal from a home subscriber server (HSS), and therefore the registration procedure of the IMS terminal is optimized, the registration time of the IMS terminal is shortened, network pay expenses for registration of the IMS terminal are reduced, and the occurrences of network congestion phenomenon when a large amount of IMS terminals are registered at the same time are reduced.

Description

technical field [0001] The present invention relates to the field of Internet Protocol Multimedia Subsystem (IP Multimedia Subsystem, IMS), in particular to a registration method, device and system of an IMS terminal. Background technique [0002] IMS is a brand-new multimedia service form, which can meet the newer and more diversified multimedia service requirements of current client terminals. Currently, IMS is considered to be the core technology of next-generation networks, and it is also an important way to solve the convergence of mobile and fixed networks and introduce differentiated services such as triple convergence of voice, data, and video. [0003] The International Third Generation Mobile Communications Organization (The 3 rd Generation Partnership Project, 3GPP) stipulates that an IMS terminal needs to complete a registration process to use multimedia services provided by the IMS. Such as figure 1 As shown in the figure, it is the process of interactive re...
