[0016] Figure 1 It is a schematic diagram of the internal logic and connection of the present invention; Figure 2 A schematic diagram of a called call flow in the case of a failure of the privacy number service device of the present invention; Figure 3 This is a schematic diagram of the privacy number off-site disaster recovery anchoring platform of the present invention using a group POOL method for disaster recovery. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings: The implementation process of the present invention is as follows: when a privacy number is activated, the privacy number off-site disaster recovery anchoring platform initiates registration, introduces the iFC contract trigger mechanism, and configures the trigger address as the privacy number off-site disaster recovery anchoring platform. In the iFC trigger configuration, the DefaultHandling (handling method for trigger failure) is configured as SESSION_CONTINUE, that is, when the privacy number business equipment off-site disaster recovery platform is unreachable, the call will continue to be processed normally, and will not affect the normal call of the existing network privacy number.

[0018] When the privacy number is called, the I / S-CSCF to which the privacy number belongs initiates the "INVITE" message of the SIP protocol to the off-site disaster recovery anchor platform of the privacy number according to the privacy number trigger information; the off-site disaster recovery anchor platform of the privacy number analyzes the triggered INVITE message to obtain the privacy number information; the off-site disaster recovery anchor platform of the privacy number executes the privacy number service equipment selection, and changes the called number to re-initiate the call to the privacy number service equipment. In the process of processing any privacy number call-type service, when the currently owned privacy number service equipment fails, the service can be switched to the off-site disaster recovery privacy number service equipment in seconds, thereby ensuring the continuity of the service. The application objects of the present invention are users of privacy numbers, small numbers, multiple numbers on one machine, intermediate numbers, etc.

[0019] The present invention embeds the processing of the privacy number off-site disaster recovery anchoring platform in the process of processing the privacy number call type business, which includes the following steps: Step 1) The caller initiates a call to the privacy number. The I / S-CSCF to which the privacy number belongs initiates an "INVITE" message of the SIP protocol to the privacy number off-site disaster recovery anchor platform based on the privacy number trigger information; Step 2) The privacy number off-site disaster recovery anchoring platform analyzes the triggered INVITE message to obtain the privacy number information; the privacy number off-site disaster recovery anchoring platform executes the privacy number service disaster recovery logic, replies to the "INVITE" message to the privacy number I / S-CSCF, and the called number in the message is changed to the service privacy number service equipment access number selected after executing the privacy number service disaster recovery logic, and the original called number is the original privacy number number; Step 3: The privacy number-attributing I / S-CSCF re-initiates the call to the called privacy number service device according to the called number in the INVITE message. The called privacy number service device restores the privacy number and performs related privacy number service logic processing.

[0020] Furthermore, in step 2), the privacy number service disaster recovery logic is executed in a way that each privacy number has a privacy number service device. If the privacy number service device corresponding to the current privacy number fails or is unreachable, the privacy number off-site disaster recovery anchor platform can select an available off-site disaster recovery privacy number service device according to the configuration. The privacy number off-site disaster recovery anchor platform and the privacy number service device use a SIP interface. The privacy number service device supports the privacy number off-site disaster recovery anchor platform's fault detection function for the privacy number service device, that is, it supports the sending, receiving and responding of OPTIONS.

[0021] Furthermore, the off-site disaster recovery anchor platform for privacy numbers itself adopts N+1 networking for disaster recovery and group POOL for disaster recovery. When a failure occurs in the off-site disaster recovery anchor platform, it supports handover of incoming calls to other anchor platforms for processing. The SIP interface is used between the off-site disaster recovery anchor platform and the I / S-CSCF to which the privacy number belongs, which supports the fault detection function of the I / S-CSCF for the off-site disaster recovery anchor platform, that is, it supports the reception and response of OPTIONS. The off-site disaster recovery anchor platform for privacy numbers (including disaster recovery sites) stores the full amount of privacy number data. When the production site fails, the I / S-CSCF triggers the call to the backup site.

[0022] The method of the present invention does not affect the normal business logic of the privacy number. The privacy number business equipment in the existing network only needs to extract the privacy number in the original called information and perform the original call logic when receiving a call message.

[0023] The privacy number off-site disaster recovery anchoring platform of the present invention includes the following modules: Figure 1 As shown: 1) Business control and processing module: The business control and processing module runs in the business control and processing server and is responsible for the execution of the disaster recovery logic of the privacy number service, including interacting with the media signaling integrated access module to process the call logic, selecting the service privacy number service device corresponding to the privacy number, filling in the access number, and changing the service status of the privacy number service device according to the OPTIONS message result reported by the media signaling integrated access module; 2) Media signaling integrated access module. The media signaling integrated access module consists of a separate integrated media signaling platform, implements the SIP protocol stack, is used to parse and encode SIP messages, connects to the network elements of the IMS through the SIP protocol, is responsible for accessing signaling messages outside the privacy number off-site disaster recovery anchor platform and forwarding them to the business control and processing module, is responsible for accessing and forwarding interactive signaling between the business control and processing module and the core network elements outside the privacy number off-site disaster recovery anchor platform; is responsible for the fault detection function between the I / S-CSCF and the privacy number business equipment, that is, supports the issuance, reception and response of OPTIONS; 3) Database service module: The database service module runs in the database server and is responsible for managing the corresponding relationship data of privacy numbers, privacy number service devices, and access numbers in the database, as well as interacting with the service control and processing module; 4) Privacy number registration module: The privacy number registration module runs on the privacy number registration server and is responsible for the activation of the contract data of the privacy number, pointing the privacy number trigger information to the privacy number off-site disaster recovery anchoring platform and storing the service privacy number business equipment data corresponding to the privacy number in the database service module; 5) Operation and maintenance module: The operation and maintenance module runs on the operation and maintenance server to complete the operation and maintenance functions of the platform.

[0024] The above modules interact and interface through the internal TCP / IP network of the privacy account off-site disaster recovery anchor platform.

[0025] In the above-mentioned privacy number off-site disaster recovery anchoring platform, the media signaling integrated access module accesses the INVITE message initiated in step 1) and forwards it to the service control and processing module; The service control and processing module analyzes the INVITE message in step 2) to obtain the privacy number information; the service control and processing module replies to the "INVITE" message to the privacy number I / S-CSCF through the media signaling integrated access module, and in step 3), the privacy number I / S-CSCF re-initiates the call to the privacy number service device.

[0026] By adopting the method of the present invention, there is no need to upgrade the existing core network elements to achieve the goal of triggering the privacy number off-site disaster recovery anchor platform when dialing any privacy number user, and making subsequent calls. At the same time, there is no conflict with subsequent calls of the privacy number, and there are no problems such as compatibility and resource limitation. This greatly broadens the scope of use and application scenarios, and provides the possibility of real-time switching when a privacy number business equipment fails.

[0027] Among them, the operation of the server system does not have any special software and hardware requirements, and the privacy number off-site disaster recovery anchor platform can be run on the current mainstream operating system.

[0028] The above modules reside on the corresponding servers and platforms in the form of firmware or software storage with corresponding software, and interact through the internal TCP / IP network of the privacy number off-site disaster recovery anchoring platform. The above modules can also be decomposed into several sub-modules according to the functions they can achieve, and recombined according to the actual deployment of the existing network to be located on the server and privacy number off-site disaster recovery anchoring platform that constitute this device, or some modules and sub-modules are located in the above-mentioned servers and platforms, and some are loaded in the existing network privacy number business equipment.

[0029] like Figure 2 As shown in the figure, the called party's call process in the case of a privacy number service device failure. In this process, it is assumed that the privacy number service device A to which the current privacy number belongs fails, and the privacy number off-site disaster recovery anchoring platform reselects the off-site disaster recovery privacy number service device B to re-initiate the call to the called party. The process is as follows: 1. The caller initiates a call to the privacy number. The called party I / S-CSCF of the privacy number initiates the "INVITE" message of the SIP protocol to the privacy number off-site disaster recovery anchor platform according to the privacy number trigger information; that is, Figure 2 The process indicated by number 1; 2. The privacy number off-site disaster recovery anchoring platform analyzes the triggered INVITE message to obtain the privacy number information; the privacy number off-site disaster recovery anchoring platform executes the privacy number service disaster recovery logic, determines that the privacy number service device A to which the privacy number belongs has failed or is unreachable, and replies to the "INVITE" message to the privacy number I / S-CSCF. The called number in the message is changed to the access number of the service privacy number service device B selected after executing the privacy number service disaster recovery logic, and the original called number is the original privacy number number; that is, Figure 2 The process indicated by number 2; 3. The privacy number attribution I / S-CSCF re-initiates the call to the called privacy number service device B according to the called number in the INVITE message, and the called privacy number service device B restores the privacy number and performs related privacy number service logic processing; that is, Figure 2 The process indicated by number 3.

[0030] like Figure 3 As shown, the off-site disaster recovery anchor platform for privacy numbers adopts a POOL group method for disaster recovery. The off-site disaster recovery anchor platform for privacy numbers itself adopts an N+1 networking method for disaster recovery, and the off-site disaster recovery anchor platforms A, B, and C for privacy numbers form a POOL for disaster recovery. When a failure occurs in the off-site disaster recovery anchor platform A serving the privacy number, it supports handover of incoming calls to other anchor platforms B and C for processing. The off-site disaster recovery anchor platforms A, B, and C of the privacy number respectively use SIP interfaces with the I / S-CSCF to which the privacy number belongs, and support the fault detection function of the I / S-CSCF for the off-site disaster recovery anchor platform, that is, support the reception and response of OPTIONS. The off-site disaster recovery anchor platforms A, B, and C of the privacy number all store the full amount of privacy number data. When the production site A fails in the embodiment, the I / S-CSCF triggers the call to the disaster recovery anchor platform B or C according to a certain ratio. When the privacy number's off-site disaster recovery anchor platforms A, B, and C are all abnormal, the large network I / S-CSCF device DefaultHandling is automatically triggered to achieve automatic escape of call continuation.
