A discrete user Data migration scheme considers that when a current network user opens a 5G service, all current network Data of the user is migrated to a 5G user Data Management function (UDM, Unified Data Management)/Unified Data storage function (UDR, Unified Data Management), namely Data migration of a discrete user number is carried out, when the user leaves a 5G overlay access 4G network, a 4G signaling flow does not access an original Home Subscriber Server (HSS)/Home location Register (H L R, Home L registration), and the user needs to be addressed to the 5G UDM/HSS/H L R.
The function of routing redirection for the signaling network requires that SS7 and the Diameter signaling network support configuration and routing of the full number of the discrete user, and the maximum number matching function, that is, the longest number is matched with the number segment to which the longest number belongs to different routes.

3. Code table limitation problem:
with the increasing number of users subscribing to 5G, the configuration data may reach the maximum capacity of the signaling code table, and therefore, a bottleneck exists in software design that the capacity of the Global Title (GT) code table of the existing network STP is limited.

Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
1. Consideration of Diameter signaling routing:
the DRA supports Diameter upper layer application and can be matched with a Home Subscriber Server (HSS) to realize redirection. Each HSS knows the specific migrated user, and can be judged by the HSS to inform the DRA of routing redirection.
Although Unified Data Management (UDM) is built centrally by region/province, users in one HSS in an existing network do not migrate to multiple UDMs decentralised. I.e. the routes of each HSS will be redirected to only one UDM. Route redirection may be implemented for granularity using the HSS.
The original home HSS and the new home UDM of the user are both in the same area/province, and only L DRA accessed by the original home HSS needs to be subjected to routing configuration or redirection.
2. Consideration of SS7 signaling routing:
difficulty is as follows: STP does not support MAP and cannot recognize upper applications. SS7 does not support application layer redirection and reselection.
The advantages are that: for a single subscriber, STP need only translate the e.214 and e.164 numbers of that subscriber to the UDM. The routing configuration data volume is small.
Although the UDMs are constructed in a centralized mode according to areas/provinces, users in one H L R of the current network cannot migrate to a plurality of UDMs in a scattered mode, namely, the route of each H L R is only redirected to one UDM, and the H L R can be used for realizing route redirection for granularity.
The original home H L R and the new home UDM of the user are in the same area/province, and only the L STP accessed by the original home H L R needs to be subjected to route configuration or redirection.
Fig. 1 is a schematic flowchart of a method for redirecting an application layer route according to an embodiment of the present invention, where as shown in fig. 1, the method includes the following steps:

The execution subject of the embodiment of the present invention is a user data network element, and specifically, may be an HSS supporting a Diameter interface and an H L R supporting a MAP interface, or an HSS/H L R fusion device.
Step 102: determining that the user code number belongs to a user code number of which the user data has been migrated, and returning a response message carrying a first reason value aiming at the signaling request; the first reason value is used for indicating the signaling transfer point network element to direct the route of the signaling request to a user data management function (UDM) according to configuration information.
The response message carrying the first cause value is returned here, which can be realized through configuration or through mapping relationship, specifically, the internal processing cause values corresponding to different scenes are designed, and the mapping relationship exists between the internal processing cause values and the interface cause values, and the internal processing cause values and the interface cause values are configurable. The user number to which the user data has been migrated here may be a 5G user number to which the user data has been migrated.
In one embodiment, the method further comprises: the user number belonging to the migrated user data is marked in advance. Here, the 5G user code number to which the user data has been migrated may be marked, and specifically, the marking may be performed by configuration.

Step 204: and receiving a response message which is sent by the user data network element and generated based on the signaling request and contains a first reason value.
Step 205: and according to the indication of the first reason value, directing the route of the signaling request to a user data management function (UDM) according to the configuration information, and taking the address of the UDM as a destination address in the signaling request.
Specifically, when a signaling response carrying a specific cause value is received, and a signaling request is associated, the route of the signaling request may be directed to the 5G user data management function according to the pre-configuration in step 201, and the address of the 5G user data management function may be used as the destination address in the signaling request.
In one embodiment, the method further comprises: and after receiving the signaling request, storing the signaling request. Namely, after receiving the signaling request, the signaling request is stored.
In one embodiment, the method further comprises: and when the signaling switching network element is directly connected with the user data management function, sending the signaling request to the user data management function.

Step 303: when the routing indication carried by the signaling request is: routing according to the GT routing, and routing according to the GT routing table.
Specifically, for the user number segment of the home subscriber data network element itself, the destination address of the GT routing result may be the subscriber data network element itself.
In one embodiment, said routing according to said GT routing table comprises: and sending a routing error response (UDTS) message to the signaling transfer network element aiming at the user code number which belongs to the migrated user data. Specifically, it may be that, for a 5G user whose user data has been migrated, no corresponding GT routing data is queried, and a routing error response UDTS message is returned.
Fig. 4 is a schematic flowchart of a method for redirecting routing at a routing layer according to an embodiment of the present invention, where as shown in fig. 4, the method includes the following steps:

The execution main body of the embodiment of the present invention may be a signaling transfer network element, and specifically, may be STP. Here, the signaling transfer network element is configured in advance as follows: when an error response Unit Data Service message (UDTS) generated based on a signaling request sent by a user Data network element or a subsystem number in the UDTS message indicates the user Data network element, a route of the signaling request may be directed to the UDM.
