Description

Synchronous migration method for online exporting and importing HLR/HSS user data

Technical Field

The invention relates to a user data online migration method in the field of wireless communication, in particular to a synchronous migration method for online exporting and importing HLR/HSS user data.

Background

A Long Term Evolution (LTE) is established by the international standardization organization (3 GPP), and requires network flattening and Internet Protocol (IP) packetization in consideration of the next-generation network architecture, thereby meeting the requirements of high capacity, high bandwidth, and high efficiency exchange and Evolution of a communication network.

The definition and function of Home Location Register (HLR) are proposed in international standardization protocol, which is a database responsible for mobile subscriber management, permanently stores and records the subscription data of subscribers in the administered area, and dynamically updates the Location information of subscribers so as to provide the network route of the called subscriber in the call service. Such as International Subscriber identity (IMSI) and Mobile Subscriber integrated services digital network number (MSISDN), Subscriber category, roaming capability, subscribed services and supplementary services, etc. In addition, the HLR stores dynamic data information about each home subscriber, such as the address of the switch where the subscriber is currently roaming (i.e., location information) and supplementary services assigned to the subscriber.

A Home Subscriber Server (HSS) is a Server for storing Subscriber subscription information in an Evolved Packet Core (EPC), is one of the most important network elements in an LTE system, is responsible for managing Subscriber subscription data and location information of a mobile Subscriber, and is an upgrade and evolution of a Home location register.

However, there is a certain difference between The two, for example, The HSS is used for The 4G (The 4th Generation communication system) network to protect The user 4G related subscription data and 4G location information, and The HLR is used for The legacy second Generation mobile communication technology (2G, The 2nd Generation communication system) and The third Generation mobile communication technology network (3G, The 3rd Generation communication system) to store The 2G/3G related data and 2G/3G location information; the external interface, protocol and bearing mode are different. The HSS is connected with a Mobility Management Entity (MME) and a Serving GPRS Support Node (SGSN), adopts a Diameter protocol and is based on IP bearing; the HLR is connected with a mobile switching center/visitor location register/serving GPRS support node (MSC/VLR/SGSN), adopts an MAP protocol and is based on TDM load bearing; the user authentication modes are different, the HSS supports user 4-tuple authentication and 5-tuple authentication, and the HLR supports 3-tuple authentication and 5-tuple authentication.

In order to provide uniform service experience for users, and simultaneously, an LTE network is used without changing numbers, registering and quickly changing cards, the existing network adopts HSS/HLR fusion technology to migrate user data from an HLR network element to a fused HSS network element.

The existing method extracts all user data (including authentication information) of HLR and identifies the integrity of a data table of a user, proposes a data import request to HSS and imports the data into the HSS. The existing method is a data migration mode without a data consistency comparison process, the data consistency and authentication resynchronization of user data in the migration process cannot be guaranteed, some instructions cannot be executed, especially the user data migration is carried out at the early monthly and late monthly accounting modification peak, asynchronous users are greatly increased, once the user data has problems, large-scale user quit the service, and the network risk is increased.

2) an operator operates a data import command in the configuration gateway, imports an original data table exported from the HLR, operates a data conversion command, and converts the original data table into a database table which can be identified by the HSS;

3) manually identifying whether the user ID in the database table is normal or not, and if the user ID is abnormal, exporting the data again; whether the data table of the HSS user is complete or not is identified, whether the data table meets HSS specifications or not is judged, and if the data table is incomplete, data conversion operation is carried out again;

4) an operator establishes a database table in the BE of the distributed HSS, checks the index entry, and identifies whether the database table of the distributed HSS is complete or not, and if the database table is incomplete, the retrieval operation is carried out again;
