Description

Technical Field

[0001] This invention relates to the field of communications, and more specifically, to, but not limited to, transparent data migration methods, apparatus, new HSSs, and computer storage media. Background Technology

[0002] In related technologies, transparent data refers to data related to IMS (IP Multimedia Subsystem) subscribers that is stored by the Application Server (AS) in the Home Subscriber Server (HSS). This data is defined by the AS and is transparent to the HSS, hence the name "transparent data." The purpose of this mechanism is to utilize the storage capabilities of the HSS while reducing the complexity of AS data management.

[0003] Since the transparent data is defined by the AS (Autonomous System) and stored by the HSS (High-Speed ​​Server), when the HSS needs to be cut over, the transparent data needs to be migrated to the newly created HSS. When cutting over HSSs from the same manufacturer, because the transparent data storage method is consistent, the transparent data can be directly exported from the original HSS and then imported into the new HSS. However, when cutting over HSSs from different manufacturers, due to the inconsistent transparent data storage methods and compatibility issues, it is difficult to directly export and import the transparent data. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the embodiments of this invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] Example 1:

[0028] To address this issue, embodiments of the present invention provide a transparent data migration method, such as... Figure 1 As shown, this transparent data migration includes:

[0029] S101: Create a new HSS to simulate the existing network AS.

[0030] Understandably, in related technologies, the AS can download transparent data via UDR (User Data Request) / UDA (User Data Answer) messages, update transparent data via PUR (Profile Update Request) / PUA (Profile-Update-Answer) messages, and subscribe to and unsubscribe from transparent data via SNR (Subscribe Notifications Request) / SNA (Subscribe Notifications Answer) messages. If the subscribed transparent data changes, the HSS will send a PNR (Push Notification Request) message to notify the AS.

[0031] In this embodiment of the invention, a method for migrating transparent data from an existing network HSS by simulating the existing network AS in a newly created HSS solves the problem of transparent data migration from different vendors. The transparent data is migrated from the existing network HSS to the newly created HSS. The existing network HSS and the newly created HSS can be from the same vendor or different vendors; this is not limited here. Therefore, the newly created HSS needs to simulate the existing network AS. In some embodiments, the newly created HSS adds an existing network application server (AS) configuration to simulate the existing network AS; this AS configuration includes, but is not limited to, the Sh interface.

[0032] S102: Create a new HSS and send a User Data Request Message (UDR).

[0033] In some embodiments, since the newly created HSS simulates the existing AS, the newly created HSS may send the UDR to the existing HSS to request the download of transparent data;

[0034] In some embodiments, the newly created HSS may also send a UDR to the existing network routing agent node DRA, which then forwards the UDR message to the existing network HSS. It is understood that if the existing network HSS corresponds to a directed DRA, the UDR message is sent to the DRA, which then forwards the UDR message to the existing network HSS. In this case, a Diameter link is established between the newly created HSS and the existing network DRA before the newly created HSS sends the UDR to the existing network DRA.

[0035] In some embodiments, when a new HSS corresponds to a new DRA, the new HSS can send a UDR to the new DRA, which then forwards it to the existing HSS. Of course, the new DRA has pre-established a Diameter link with the existing HSS.

[0036] In some embodiments, when a new HSS corresponds to a new DRA, the new HSS can send a UDR to the new DRA, which then forwards it to the existing DRA, and the existing DRA forwards it to the existing HSS. Of course, the new DRA establishes a Diameter link with the existing DRA beforehand.

[0037] It is understood that, in the embodiments of the present invention, sending a UDR by creating a new HSS includes: obtaining a list of users to be cut over by creating a new HSS, and sending a UDR message for each user to be cut over; that is, sending a UDR message for each user to be cut over. In some embodiments, it may be sending a UDR message for all users to be cut over. The obtaining of the list of users to be cut over by creating a new HSS includes, but is not limited to, sending a list of users to be cut over by IMS, or sending a list of users to be cut over by the manufacturer.

[0038] S103: The newly established HSS receives user data response messages (UDA). The UDA message includes transparent data from the existing HSS.

[0039] In some embodiments, the newly created HSS may receive UDA messages directly from the existing HSS. That is, the existing HSS receives UDR messages from the simulated existing AS, sends UDA messages to the newly created HSS, and carries an XML file containing the transparent data requested by the newly created HSS in the UDA message.

[0040] In some embodiments, a newly created HSS may receive UDA messages forwarded by the DRA from the existing HSS. This can be either a newly created HSS receiving UDA messages forwarded by the existing DRA from the existing HSS, or a newly created HSS receiving UDA messages forwarded by the new network DRA from the existing HSS.

[0041] S104: Create a new HSS to parse transparent data from UDA messages and write it to the database.

[0042] Since the UDA message carries transparent data, the newly created HSS parses the transparent data and writes it to the database, indicating that the transparent data migration is successful. In this embodiment of the invention, the newly created HSS can also record a list of users whose transparent data migration failed. For example, it can compare the obtained list of users to be cut over with the transparent data written to the database to determine the list of users whose transparent data migration failed. In some embodiments, the newly created HSS can also analyze the reasons for the transparent data migration failure and resolve them accordingly. For example, the newly created HSS can resend the UDR message.

[0043] The transparent data migration method provided in this invention addresses the significant difficulties encountered during HSS cutover between different vendors, stemming from inconsistent transparent data storage methods and inter-vendor cooperation issues. By using a newly created HSS to simulate the existing AS and read transparent data from the existing HSS, this method solves the challenge of transparent data migration between vendors. This technology is based on messages defined by 3GPP protocols, requires no cooperation from the existing network vendor, and does not require modifications to the existing network configuration, enabling smooth transparent data migration.

[0044] Example 2:

[0045] To facilitate understanding, this embodiment of the invention uses a specific example to illustrate the transparent data migration method, such as... Figure 2 As shown, this transparent data migration method includes:

[0046] S201: Create a new HSS to obtain the list of users to be cutoverdone.

[0047] S202: Create a new HSS to simulate the existing AS network and add relevant configurations.

[0048] S203: Establish a Diameter link between the newly built HSS and the existing DRA.

[0049] S204: Create a new HSS and send a UDR message to the existing DRA to read transparent data.

[0050] In this embodiment of the invention, the newly created HSS sequentially reads the users to be cut over from the list of users to be cut over, and sends a UDR message to the existing DRA through the Sh interface for each user to be cut over.

[0051] S205: The live DRA forwards the UDR message to the live HSS.

[0052] S206: The live HSS returns a UDA message to the live DRA, which includes transparent data of the users to be cut over.

[0053] After receiving the UDR message, the live HSS obtains the transparent data corresponding to the user to be cut over. The live HSS then sends a UDA message to the live DRA, in which the UDA message carries the transparent data of the user to be cut over in XML format.

[0054] S207: The existing DRA forwards UDA messages to the newly created HSS.

[0055] S208: Create a new HSS to parse transparent data and write it to the database. Transparent data migration successful.

[0056] In this embodiment of the invention, the newly created HSS compares the transparent data in the database with the user list file to be cut over, records the users whose transparent data migration failed, analyzes the reasons for the failure to migrate the transparent data and solves them in a targeted manner. The solutions include, but are not limited to, reading again through UDR messages.

[0057] In this embodiment of the invention, a transparent data migration method is also provided. This method is implemented by a newly created HSS, including: the newly created HSS obtaining a list of users to be migrated; the newly created HSS simulating the existing AS and adding relevant configurations; the newly created HSS sending a User Data Request Message (UDR) to the existing HSS; the newly created HSS receiving a User Data Request (UDA) message returned by the existing HSS, the UDA message including transparent data from the existing HSS; and the newly created HSS parsing the transparent data from the UDA message and writing it to a database. In other words, the newly created HSS simulates the existing AS and directly reads transparent data from the existing HSS.

[0058] The transparent data migration method provided in this invention addresses the significant difficulties encountered during HSS cutover between different vendors, stemming from inconsistent transparent data storage methods and inter-vendor cooperation issues. By using a newly created HSS to simulate the existing AS (Application Server) directly or indirectly reading transparent data from the existing HSS, this method solves the challenge of transparent data migration between vendors. Based on messages defined by 3GPP protocols, this technology requires no cooperation from the existing network vendor or modification of existing network configurations, enabling smooth transparent data migration.

[0059] Example 3:

[0060] This invention also provides a method for creating a new HSS, see [link to relevant documentation]. Figure 3 As shown, it includes a processor 301, a memory 302, and a communication bus 303, wherein:

[0061] Communication bus 303 is used to realize the connection and communication between processor 301 and memory 302;

[0062] The processor 301 is used to execute one or more computer programs stored in the memory 302 to perform the following steps:

[0063] Create a new HSS to simulate the existing AS network;

[0064] The newly established HSS sends a User Data Request Message (UDR);

[0065] The newly established HSS receives User Data Response Messages (UDA), which include transparent data from the existing HSS network.

[0066] Create a new HSS to parse transparent data from UDA messages and write it to the database.

[0067] In this embodiment of the invention, a new HSS is added with AS configuration to simulate the existing network AS; the new HSS obtains a list of users to be cut over and sends a UDR message for each user to be cut over. A Diameter link is established between the new HSS and the DRA. The new HSS sends a UDR to the existing network HSS through the DRA to obtain transparent data in the existing network HSS. For example, the new HSS sends a UDR to the DRA, and the DRA forwards the UDR message to the existing network HSS. Then the new HSS receives the UDA message forwarded by the DRA from the existing network HSS.

[0068] In this embodiment of the invention, after the newly created HSS parses transparent data from the UDA message and writes it to the database, it compares the obtained user list file to be cut over with the transparent data written to the database and records the list of users whose transparent data migration failed.

[0069] This invention also provides a transparent data migration device, such as... Figure 4As shown, the transparent data migration device includes:

[0070] Simulation module 401 is used to simulate the existing network AS;

[0071] Sending module 402 is used to send User Data Request Message (UDR);

[0072] The receiving module 403 is used to receive user data response messages (UDA), which include transparent data in the existing HSS network.

[0073] Parsing module 404 is used to parse transparent data from UDA messages and write it to the database.

[0074] This invention also provides a computer storage medium storing one or more programs that can be executed by one or more processors to implement the steps of the transparent data migration method as described in Embodiments 1 and 2.
