Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

First embodiment

To better illustrate the present embodiment, the following describes the problems of the prior art with reference to fig. 1 and 2:

as shown in fig. 1, a schematic diagram of a network architecture of a 5G core network is defined in a 3GPP (3rd Generation Partnership Project) TS 23.501 protocol, and the UDM is located in the HPLMN and has functions of calculating a user authentication vector, user mobility management, and user subscription data management.

Fig. 2 is a schematic diagram of a mobility management operation timing structure of a conventional 5G mobile communication network, which specifically includes:

step 101, each UDM configures user data routing information, when the UDM registers a service to an NRF (Network discovery Function), the UDM carries the user data routing information, the NRF caches the user data routing information to the local, the user data routing information refers to a corresponding relationship between a user number segment or number and a user attribution UDM, and the NRF provides the service registration and service discovery functions;

step 102, a user accesses an NF (Network Function), such as an AMF (Access Management Function)/SMF (Session Management Function), and queries an NRF for UDM address information (e.g., IP address and port) according to a user identifier, such as IMSI (International Mobile Subscriber identity), MSISDN (Mobile Subscriber identity), etc.

Step 103, NRF returns user routing data home UDM address to user access NF.

And step 104, the user access NF sends an operation request to the user data attribution UDM.

And 105, after the UDM processes the operation request, returning an operation response to the NF accessed by the user.

The existing mobility management operation of the 5G mobile communication network has the following problems:

1) the operation and maintenance personnel need to configure user data routing information in a plurality of UDMs, the maintenance workload is large, the configuration of user number sections among the UDMs can be overlapped and collided, in order to reduce the workload of configuring the user data routing information, operators generally adopt the corresponding relation of the user number sections and the UDMs to be planned in advance, the user number sections with large range are configured in the user data routing information, but precious number resources are wasted, and when users change cards/numbers across the UDMs, the user data routing information needs to be changed or the user number sections need to be reserved for changing cards/numbers. The routing information of the user data is inaccurate, the user can not find the accurate UDM when accessing NF, the service operation fails, and the complaint of the user is caused.

2) Before the user access NF processes the mobility management operation related to the UDM, the user access NF and the NRF need to be inquired according to the user number to acquire the UDM, and the processing performance of the user access NF and the NRF is reduced.

Based on the problem of the mobility management operation of the existing 5G mobile communication network, as shown in fig. 3, a first embodiment of the present application provides a user routing method, where the method is used in a UDM, and the method includes:

UDM32 for providing user authentication, user mobility management functions.

UDR33 for providing user data storage and management functions.

The PROVISION34 is a user data acceptance subsystem, requests to create and store user data in the UDR33, and updates user data routing information in the URDC after successful operations of user number allocation, number selling, card changing and number changing.

step 401, the proxy executes service acceptance, and writes user data in the UDR.

Step 402, the proxy accepts successful operations of number allocation, number cancellation, card change and number change services, and notifies the URDC to change the user data routing information. For example: and (4) adding the corresponding relation between the IMSI/MSISDN number of the user and the UDR address when the number is released, deleting the user data routing information when the number is cancelled, and changing the user data routing information when the card is changed or the number is changed.

Step 403, the user accesses the NF to inquire the address information of the UDM of the local network to the NRF.

In step 404, the NRF returns the address information of the UDM of the home network.

In step 405, the user access NF sends an operation request to the local UDM.

And step 406, the UDM queries the URDC according to the user identifier to acquire a home UDR of the user data.

In step 407, the UDM accesses the user data of the home UDR.

In step 408, the UDR returns the user data access results to the UDM.

In step 409, the UDM returns the operation result to the user access NF.
