example 212

[0213] The processor 1601 may include a single connection control instance associated with the at least one active slice 120 and the at least one idle slice 110 for initiating the connection establishment of the at least one idle slice 110 (eg, the above-mentioned combine Figure 14 The single connection control instance 1411).

[0214] Figure 17 It shows a block diagram of an exemplary radio access network (radio access network, RAN for short) entity (for example, the RAN entity 220 described above with reference to the preceding figures) according to an implementation manner. The RAN entity 220 may be a base station, such as the combination of the above figure 1 The gNBs 106a, 106b, 106c described in (a) and (b). The RAN entity 220 includes a processor 1701, for example, used to process the functions described above in conjunction with the preceding figures.

Abstract

The present invention relates to a user equipment (UE for short), comprising a processor, configured to: receive an activation command for at least one idle slice among a plurality of slices, wherein the activation command commands execution of the at least one idle slice connection establishment; setting the UE to an active state to enable the connection establishment of the at least one idle slice. The present invention also relates to a core network (referred to as CN) system, comprising: an inter-slice control agent (ICA-CN), used to be associated with or can be associated with a user equipment (referred to as UE) from At least one slice among the plurality of slices collects context information; at least one CN instance is used to send a connection request to the UE, and the connection request requests the UE to establish a connection with at least one idle slice among the plurality of slices . The present invention also relates to a radio access network (radio access network, RAN for short) entity.

Description

technical field [0001] The present invention relates to a technology for slice activation in a multi-slice network, especially in a next-generation wireless network. Background technique [0002] Network slicing is one of the key building blocks of the fifth-generation mobile and wireless communication network (5G), also known as new radio (NR) or new radio access technology (RAT) or next-generation wireless networks. First, its main goal is vertical industry integration. The network slice can be defined as a logical network (providing telecommunication services and network capabilities), including an access network (AN for short) and a core network (CN for short), see 3GPP TR 23.799 "Research on Next Generation System Architecture (version 14)", v0.7.0 (August 2016). 3rd Generation Partnership Project (3 rd The Generation Partnership Project (3GPP for short) standardizes network slicing from two aspects: core network (CN for short) and radio access network (RAN for shor...
