Embodiment 1

[0135] An embodiment of the present invention provides a method for restoring a registration state, which is applied to a SIP terminal device that provides interactive services for a SIP account. Such as figure 2 As shown, the method includes:

[0136] Step S201, after determining that the device is restarted, read the registration information of the SIP account in the permanent storage device to the memory, wherein, periodically save the registration information of the SIP account in the memory to the permanent storage device;

[0137] In the embodiment of the present invention, the SIP terminal device can be an IPPBX device that provides communication services for different user terminals such as telephones, and can initiate registration to the IMS network for at least one public network number (SIP account) assigned to itself.

[0138] The data in the device memory will be lost after the device restarts, so the registration information of the SIP account stored in the mem...

Embodiment 2

[0204] refer to Figure 8 , is a schematic flowchart of a method for restoring a registration status provided by an embodiment of the present invention. As shown in the figure, the method flow includes:

[0205] Step S801, when the SIP terminal device is running, record the registration information of the corresponding SIP account into the memory in real time;

[0206] Step S802, when the determined persistence period is reached, the registration information of the SIP account in the persistent memory is saved to a permanent storage device;

[0207] Wherein, according to the preset fixed persistence period, the registration information of all SIP accounts in the memory is saved in the permanent storage device; or, according to the re-registration period corresponding to all the SIP accounts in the memory, a dynamic persistence period is determined, According to the dynamic persistence period, the registration information of all SIP accounts in the memory is stored in the per...

Embodiment 3

[0217] refer to Figure 9 , is a schematic flowchart of a method for restoring a registration status provided by an embodiment of the present invention. As shown in the figure, the method flow includes:

[0218] Step S901, when the SIP terminal device is running, record the registration information of the corresponding SIP account into the memory in real time;

[0219] Step S902, according to the value range of the re-registration period corresponding to each SIP account in the memory, and the persistence period corresponding to different value ranges, determine the persistence period corresponding to each SIP account;

[0220] Preferably, the persistence period corresponding to each SIP account is determined according to the corresponding relationship between re-registration periods and persistence periods in different ranges shown in Table 1 in the above embodiment.

[0221] Step S903, for each SIP account, when it is determined that the corresponding persistence period is...

Abstract

The invention provides a registration state recovery method and device. The method is applied to SIP terminal equipment for providing interactive service for a session initiation protocol SIP account,and comprises the following steps: after that the equipment is restarted is determined, reading registration information of the SIP account in permanent storage equipment into a memory, and periodically storing the registration information of the SIP account in the memory into the permanent storage equipment; comparing the current time point with a re-registration time point corresponding to theSIP account; sending initial registration request information to a SIP server for the SIP account of which the current time point reaches or exceeds the re-registration time point, and sending re-registration request information to the SIP server when the SIP account of which the current time point does not exceed the re-registration time point reaches the corresponding re-registration time point.According to the method disclosed in the solution provided by the invention, the problems of overlarge information interaction amount between the SIP terminal equipment and the SIP server and overlong service unavailable time of the terminal equipment in a conventional registration state recovery method are solved.

Description

technical field [0001] The invention relates to network function virtualization technology, in particular to a method and equipment for restoring registration state. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a brand-new multimedia service form, which can meet the needs of existing terminal customers for newer and more diversified multimedia services. [0003] IMS can not only realize the initial VoIP (Voice over IP) service, but more importantly, IMS will manage network resources, user resources and application resources more effectively, improve the intelligence of the network, and enable users to cross various networks and Use a variety of terminals to experience a converged communication experience. As a communication framework, IMS has created a new telecom business model and expanded the development space of the entire information industry. [0004] In the IMS service system, SIP (Session Initiation Protocol, Session Initi...
