Description

Method and device for redirecting routing of application layer and computer readable storage medium

Technical Field

The present invention relates to communications technologies, and in particular, to a method, an apparatus, and a computer-readable storage medium for routing redirection at an application layer and a routing layer.

Background

When 5G adopts SA architecture to provide basic network service, 5G user data has 2/3/4/5G/IMS data fusion requirement. The target scheme for user data fusion is full replacement or full upgrade. The transition scheme involves a partial user-local or discrete user data migration scheme.

A discrete user Data migration scheme considers that when a current network user opens a 5G service, all current network Data of the user are 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 coverage access 4G network, a 4G signaling flow does not access an original Home Subscriber Server (HSS)/Home Location Register (HLR), and the user needs to be addressed to the 5G UDM/HSS/HLR.

The function of routing redirection for signaling network requires that SS7 and Diameter signaling network support configuration and routing of full number of discrete user, and maximum number matching function, i.e. the longest number is matched with the number segment to which it belongs to different routes.

The prior art has the following problems: signaling Transfer Point (STP) and Routing Agent node (DRA) already support related functions, but discrete user Routing data configuration amount is large, complexity is high, timeliness requirement is high, and code table capacity is limited.

1. The problem of configuration timeliness:

the signaling routing data are number segment data, and are configured through network management without a large amount of discrete user full number real-time configuration experience combined with the opening process.

2. Configuration complexity issues:

for a single user, the DRA needs to configure the route per application interface. At present, HSS relates to S6a/Cx/Sh/Zh/SLh/SWx/S6t/S6c interfaces, user signing services are different, configuration interfaces are different, and compared with number segment configuration complexity is greatly increased.

3. Code table limitation problem:

with the increasing number of users signing 5G, the configuration data may reach the maximum capacity of the signaling code table, so that a bottleneck exists in the 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 using HSS for granularity.

The original HSS and the new UDM are in the same area/province, and only the LDRA accessed by the original HSS needs to perform routing configuration or redirection. The route redirection notification does not need to be transmitted across regions/provinces, and the influence surface is small.

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 UDMs are built centrally per area/province, users in one HLR of the current network do not migrate to multiple UDMs decentralised. I.e. the routes of each HLR will only be redirected to one UDM. Routing redirection may be implemented using the HLR for granularity.

The original HLR and the new UDM are in the same area/province, and only the routing configuration or redirection is needed to be carried out on the LSTP accessed by the original HLR. The route redirection notification does not need to be transmitted across regions/provinces, and the influence surface is small.

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:

step 101: and receiving a signaling request containing the user code number sent by the signaling transfer network element.

The execution main body of the embodiment of the invention is a user data network element, and specifically can be HSS supporting a Diameter interface and HLR supporting an MAP interface, or HSS/HLR fusion equipment.

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 cause 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 returning of the response message carrying the first cause value may be implemented by configuration, or may be implemented by mapping relationship, and specifically, the internal processing cause values corresponding to different scenarios are designed, and have mapping relationship with the interface cause value, and 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 code numbers belonging to the migrated user data are 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.

Here, the signaling transfer network element is preconfigured as follows: for a signaling request that has been sent, after receiving a first cause (where the first cause value may be included in a returned response message), the routing of the signaling request may be directed to the UDM.

Step 202: a signaling request containing a user code number is received.

Step 203: and sending the signaling request to a user data network element to which the user belongs according to the user number segment in which the user number is positioned.

Specifically, when the execution main body of the embodiment of the present invention is STP, the signaling request including the subscriber number is received, and the signaling request may be forwarded to the HLR to which the subscriber belongs according to the subscriber number segment.

When the execution main body of the embodiment of the invention is DRA, the signaling request containing the user number is received, and the signaling request can be forwarded to the HSS to which the user belongs according to the user number section.

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, the signaling request is sent to the user data management function.

Wherein the configuring the GT routing table comprises: setting the destination address of the GT route as the user number segment belonging to the user data network element per se; GT route is not configured for the user code number belonging to the user data migrated.

Step 302: and receiving a signaling request containing the user code number sent by the signaling transfer network element.

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:

step 401: and when an error response unit data service message (UDTS) message generated based on a signaling request and sent by a user data network element or a subsystem number in the UDTS message of the unit data service message is received and indicated as the user data network element, the configuration points the route of the signaling request to a user data management function (UDM) to obtain corresponding configuration information.

The execution subject 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.

Step 402: a signaling request containing a user code number is received.

Step 403: when the destination address corresponding to the user number segment where the user number is located is a user data network element, the routing indication in the signaling request is modified into: and routing according to the global code GT, and sending the signaling request to the user data network element.

Specifically, routing is performed according to the subscriber number segment, and if the destination address is the subscriber home HLR, the routing indication in the signaling request may be modified to be "routing according to GT" and forwarded to the subscriber home HLR.

Step 404: and when an error response UDTS message generated by the user data network element based on the signaling request or a subsystem number in the UDTS message is received and indicates the user data network element, 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.

The configuration information here is the content configured in advance in step 401, specifically, the route configured for the signaling request here points to the user data management function UDM, and may be to point the route of the signaling request corresponding to the error response to the 5G user data management function, and may use the address of the 5G user data management function as the destination address in the signaling request.
