Description

Slice registration method, device, terminal and network node

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202010683117.X filed in China on Jul. 15, 2020, the entire contents of which are incorporated herein by reference.

technical field

The present disclosure relates to the field of communication technologies, and in particular, to a slice registration method, device, terminal, and network node.

Background technique

The slice registration process of the related art is characterized by randomness, as shown in Figure 1:

TA area A only supports slice 1 registration, TA area B supports slice 1 and slice 9 registration, and TA area C supports slice 1 and slice 10 registration;

Assume that the Configured NSSAI set of terminal 1 is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

Initially, the terminal 1 initiates the tracking area registration process in the TA area A and the registration area allocated to the terminal by the network side is the TA area {A, B, C}. If the terminal then initiates the slice registration process in the TA area A and the requested slice set is {1, 2, 3, 4, 5, 6, 7, 8}, after the registration area A initiates the slice registration process, the terminal can only successfully register slice 1, and the registration of slice 2 to slice 8 will be rejected. The terminal moves to the border area of TA area A and TA area B, and slice 9 can also be registered, but the terminal in idle (idle) and/or inactive (inactive) state does not know that TA area B supports slice 9 registration, because the terminal does not move out The registered tracking area {A, B, C}, the terminal will not blindly initiate slice 9 registration before the slice 9 service is initiated. The problem is that once the user tries to initiate the slice 9 service, it can only temporarily perform slice 9 registration. If the registration of slice 9 is initiated in tracking area B, the registration of slice 9 is successful; if the terminal initiates registration of slice 9 in tracking area C, the registration of slice 9 fails. The above scenario has the following problems:

Disadvantage 1: In the random slice registration process in the related art, the terminal cannot know the changes of the registration authority of other TA areas or cell slices in time. As shown in Figure 1, the terminal cannot perceive that TA area B or C supports different support than TA area A. Slice collection, so that the terminal cannot perform local adaptive slice registration;

Disadvantage 2: In the random slice registration process in the related art, the terminal cannot optimize the slice set to be registered according to the new TA area or the change of the cell slice registration authority. As shown in Figure 1, the terminal cannot perceive the relative TA area B or C relative to the TA. Area A supports different slice sets, which causes the terminal to register slices other than slice 1 and slice 9 in TA area B. For example, the terminal registers slice 10 in TA area B, but the final result is to reject slice 10 registration;

Disadvantage 3: In the random slice registration process in the related art, the terminal does not always try to register all the Configured NSSAI sets, because a maximum of 8 slice registrations are attempted at a time, while the Configured NSSAI may have dozens of types, and the slice registration process is frequent It is also a network burden, so the limited slice registration process can only be carried out by implementing algorithms such as user preferences, as shown in Figure 1, if slice 9 has not tried to register in TA area A, then when the terminal moves to TA area B, the terminal does not method to determine whether slice 9 should be registered, because the terminal tracking area is still {A, B, C}, if slice 9 is registered only when the service of slice 9 is initiated, the service delay brought by the registration process will reduce the user experience; another On the other hand, if the terminal first selects the TA area B cell to register the slice 10 at the junction of the TA area B and the TA area C, the registration process of the slice 10 fails, and the terminal needs to reselect the cell in the TA area C to register the slice 10 again to succeed. From the failure to register the slice 10 in the TA area B to the time it is reselected to the cell in the TA area C to register the slice 10 again, the time delay is longer, and the user experience is worse.

To sum up, the service delay caused by the inability of the terminal to perform local adaptive slice registration will greatly reduce the user experience.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure more clear, detailed description will be given below with reference to the accompanying drawings and specific embodiments.

First, the relevant content is introduced as follows:

Slice (Slice) is a new concept introduced by the New Radio Access Technology (New RAT, NR) system. The main purpose is to divide different resource management modes for different services, so as to increase service isolation and optimize according to service types. Resource management method; specifically, about NR slices:

A network slice is a service-oriented resource encapsulation concept. A network slice is uniquely identified by the Network Slice Selection Assistant Identity (NSSAI), and also corresponds to a type of resource configuration. Different core networks can support different types of network slices according to requirements. Different from Long Term Evolution (LTE) system registration, a terminal needs to register a slice before using it in the network. The session establishment process corresponding to the slice can be initiated only after the slice is successfully registered. During the slice registration process, the NSSAI information (Request NSSAI) requested by the terminal to be registered is selected from the Configured NSSAI or Default NSSAI stored in the terminal, and the terminal can only request to register a maximum of 8 S-NSSAI (Single NSSAI) information at a time; Subscription information, Request NSSAI of the terminal, slice information supported locally, and Allowed NSSAI and Rejected NSSAI of the local policy generation terminal.

The terminal will also pre-configure or obtain the Configured NSSAI from the core network. This configuration is unique to the PLMN. If a PLMN configured by the terminal is not configured with the Configured NSSAI, the Default NSSAI information will be used.

NR system core network definition, a slice corresponds to an S-NSSAI (Single NSSAI, a single network slice selection auxiliary identifier) identifier, an S-NSSAI identifier is identified by the slice type Slice/Service Type (Slice/Service Type, SST) and slice distinction It is composed of a Slice Differentiator (SD), wherein the slice type identifier SST occupies 8 bits and must appear, and the slice distinguisher SD occupies 24 bits and is optional.

In addition, the application of slicing on the terminal side adopts the principle of registering first and then initiating services. The NSSAI information (Request NSSAI) that the terminal requests to register is selected from the Configured NSSAI or Default NSSAI stored in the terminal, and the terminal can only request to register at most 8 at a time. S-NSSAI information, the consequence of this design is that if the slice service that the terminal actually intends to initiate is not registered, the terminal can only initiate the slice re-registration process for the slice corresponding to the service to be initiated. Even if the registration is successful, the slice re-registration process will not be performed It brings additional delay; on the other hand, if the slice re-registration process initiated by the terminal fails, it also brings unnecessary waiting delay on the user side. Generally speaking, the slice registration process of related technologies brings disadvantages to users. user experience.
