S101, receiving information of a network slice NS, wherein the information of the NS is generated when the NS is created.
As one example, the NS information includes, but is not limited to, a combination of one or more of the following: the number of the NS, the type of the NS, the internet protocol (Internet Protocol, IP) address the NS exposes to the outside, and the tenant information of the NS.
NS is a sub-network that satisfies certain network functions, such as internet technology multimedia system (Internet technology Multimedia System, IMS) network slice, fifth Generation mobile communication technology Core (5 GC) network slice.
S102, storing the information of the NS in a unified data manager UDM.
As an example, the unified data manager (Unified Data Management, UDM) includes therein user subscription data including information of NS of the user subscription.
And S103, if a request for inquiring the NS subscribed by the user is received, acquiring information of a first NS from the UDM, wherein the first NS is the NS subscribed by the user.
As one example, the NS subscribed to the user may be one or more, and thus the number of the first NS may be one or more.
For example, the UDM stores NS1 information, NS2 information, and NS3 information, where NS1 and NS2 sign up with the user respectively; and if a request for inquiring the NS subscribed by the user is received, acquiring the information of the NS1 and the information of the NS2 from the UDM.
And S104, transmitting the information of the first NS acquired from the UDM.
As an example, the information of the first NS acquired from the UDM is sent to the core network.
For example, the information of the first NS acquired from the UDM is sent to the 5GC network. The 5GC network is responsible for bearer layer access for the user equipment.
The execution main body of the network slice information management method in the embodiment of the invention can be a unified data manager, and of course, the execution main body of the network slice information management method can also be other devices for storing user data.

Because the user equipment can use the NS selected by the user, the requirement of the user for automatically selecting the NS is met, and the flexibility of using the NS by the user equipment is improved. For example, the user signs up for NS1 and NS2, NS1 is better in terms of making a call, NS2 is better in terms of surfing the internet, the user equipment of the user currently uses NS1, and if the user wants to use the network, the user equipment can switch to use NS2, so as to ensure the surfing service of the user.
In one embodiment of the present invention, S103 includes:
establishing an association relationship between information of a user and the first NS; if a request for inquiring the NS subscribed by the user is received, information of the first NS is acquired from the UDM according to the association relation.

As one example, by associating the subscription information of the user with the information of the first NS, an association relationship between the user and the information of the first NS is established, and the subscription information of the user is generated when the user signs up with the first NS.
In one embodiment of the present invention, after S102, the method for managing network slice information further includes:
receiving modified information of a second NS, wherein the second NS is the modified NS, and the information of the second NS is stored in the UDM; and updating the information of the second NS stored in the UDM according to the information modified by the second NS.
Note that the information of the second NS being stored in the UDM means that the information of the second NS before modification is stored in the UDM. The second NS may be the first NS, or the second NS may not be the first NS.
As one example, the information of the second NS stored in the UDM is updated by replacing the information of the second NS stored in the UDM with the information modified by the second NS.
For example, the UDM stores the information of NS1, the information of NS2, and the information of NS3, receives the information modified by NS1, and replaces the information of NS stored in the UDM with the information modified by NS 1.
In one embodiment of the present invention, after S102, the method for managing network slice information further includes:
