Description

Slice registration method, device, terminal and network node

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a slice registration method, an apparatus, a terminal, and a network node.

Background

The existing slice registration process has the characteristic of randomness, as shown in fig. 1:

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

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

initially, the terminal 1 initiates a tracking area registration process in TA area a and the registration area allocated to the terminal by the network side is TA area { a, B, C }, if the terminal then initiates a slice registration process in TA area a and the requested slice set is {1, 2, 3, 4, 5, 6, 7, 8}, then after the registration area a initiates the slice registration process, the terminal can only successfully register slice 1, registration of slice 2 to slice 8 will be rejected, slice 9 can also be registered as the terminal moves to the TA area a-TA area B boundary area, but idle and/or inactive state terminals do not know that TA area B supports slice 9 registration because the terminal does not move out of its registered tracking area { a, B, C }, the terminal will not blindly initiate slice 9 registration before slice 9 service initiation, the problem is that slice 9 registration can only be performed temporarily once the user is ready to attempt to initiate slice 9 service, if the slice 9 registration is initiated in the tracking area B, the slice 9 registration is successful; if the terminal initiates slice 9 registration in the tracking area C, slice 9 registration fails, and the above scenario has several problems as follows:

disadvantage 1: in the existing random slice registration process, a terminal cannot timely know the change condition of slice registration authority of other TA areas or cells, as shown in FIG. 1, the terminal cannot perceive that a TA area B or C supports different slice sets relative to a TA area A, so that the terminal cannot perform local adaptive slice registration;

and (2) disadvantage: in the existing random slice registration process, a terminal cannot optimize a slice set requested to be registered according to the change of a new TA area or cell slice registration authority, as shown in fig. 1, the terminal cannot perceive that a TA area B or C supports different slice sets relative to a TA area a, so that the terminal registers other slices except for a slice 1 and a slice 9 in the TA area B, for example, the terminal registers a slice 10 in the TA area B, and the final result is that the slice 10 registration is rejected;

disadvantage 3: in the existing random slice registration process, a terminal does not always try to register a Configured NSSAI set once, because 8 slice registrations are tried at most once, while the Configured NSSAIs may be dozens, and a frequent slice registration process is also a network burden, the limited slice registration process can only be performed by using implementation algorithms such as user preference, for example, as shown in fig. 1, if a slice 9 is not tried to be registered in a TA area a, when the terminal moves to the TA area B, the terminal cannot judge that the slice 9 should not be registered, because a terminal tracking area is still { a, B, C }, if the slice 9 is registered only when a slice 9 service is initiated, service delay caused by the registration process reduces user experience; on the other hand, if the terminal first selects the TA area B cell registration slice 10 at the boundary between the TA area B and the TA area C, the slice 10 registration process fails, the terminal further needs to reselect the cell re-registration slice 10 in the TA area C to succeed, the time delay consumed by the terminal from the time when the TA area B registration slice 10 fails to the time when the terminal reselects the cell re-registration slice 10 in the TA area C is larger, and the user experience is worse.

In summary, the service delay caused by the terminal not being able to perform local adaptive slice registration may greatly reduce the user experience.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The relevant contents are first described as follows:

slice (Slice) is a concept newly introduced by an NR (New RAT, New radio access technology) system, and mainly aims to divide different resource management modes for different services, so that a resource management mode can be optimized according to a service type while service isolation is increased; specifically, regarding NR slices:

a Network Slice is a service-oriented resource encapsulation concept, and a Network Slice is uniquely marked by NSSAI (Network Slice Selection Identity) and corresponds to a type of resource configuration. Different core networks can support different types of network slices according to requirements, and different from registration of an LTE (long term evolution) system, the method is that a terminal needs to perform registration of a slice before using the slice in a network, and the terminal can initiate a session establishment process corresponding to the slice only after the slice is successfully registered. In the slice registration process, NSSAI information (Request NSSAI) requested to be registered by a terminal is selected from Configured NSSAI or Default NSSAI stored by the terminal and restricts the terminal to Request to register 8S-NSSAI (Single NSSAI) information at most once; and the core network generates the Allowed NSSAI and the Rejected NSSAI of the terminal according to the terminal subscription information, the Request NSSAI of the terminal, the slice information supported locally and the local strategy.

The terminal may also pre-configure or obtain Configured NSSAI from the core network, the configuration being PLMN-unique, and use Default NSSAI information if a certain PLMN Configured by the terminal is not Configured with Configured NSSAI.

The NR system core network is defined, where one Slice corresponds to one S-NSSAI (Single NSSAI, Single-network-Slice selection auxiliary identifier) identifier, and one S-NSSAI identifier is composed of a Slice Type identifier SST (Slice/Service Type) and a Slice differentiation identifier SD (Slice differentiation identifier), where the Slice Type identifier SST occupies 8 bits and must occur, and the Slice differentiation identifier SD occupies 24 bits and can occur selectively.

In addition, the application of the slice on the terminal side is carried out by adopting the principle of firstly registering and then initiating the service, the NSSAI information (Request NSSAI) requested to be registered by the terminal is selected from Configured NSSAI or Default NSSAI stored by the terminal, and the terminal is constrained to be only capable of requesting to register 8S-NSSAI information at most once, so that the design brings about the consequence that if the slice service actually prepared to be initiated by the terminal is not registered, the terminal can only initiate the slice re-registration process for the slice corresponding to the service to be initiated, and even if the registration is successful, the slice re-registration process also brings extra time delay; on the other hand, if the slice re-registration process initiated by the terminal fails, the user side also has useless waiting time delay, and in general, the existing slice registration process brings unfavorable user experience to the user.

Based on the above, the present invention provides a slice registration method, applied to a terminal, for solving the problems of unreasonable slice registration scheme and long slice registration delay in the prior art, as shown in fig. 2, including:

step 21: acquiring a frequency point set generated by a first network node and identification information of slice types supported by each frequency point in the frequency point set;
