no. 1 Embodiment

[0107] Such as Figure 4 Shown is a schematic diagram of a process in which a control plane functional entity on the access network side selects a network slice for a terminal.

[0108] Step 401: The control plane functional entity on the access network side exchanges information about the network slices supported by the core network with the public control plane entity on the core network side in advance, mainly to obtain the identifier of the network slice configured on the core network side, so that the network slices on the access network side The identity of each network slice configured by the access network and the core network is stored in the control plane functional entity.

[0109] If the core network side is configured with a default network slice, the identifier of the network slice configured on the core network side obtained by the control plane functional entity on the access network side includes the identifier of the default network slice, and also includes t...

no. 2 Embodiment

[0120] Such as Figure 5 Shown is a schematic diagram of a process in which a control plane functional entity on the access network side selects a network slice for a terminal.

[0121] Step 501: The control plane functional entity on the access network side pre-stores the binding relationship between each network slice configured in the access network and the execution entity, wherein the control function of the network slice is configured in the control plane of the access network In the user plane entity, the user plane function is configured in the user plane entity of the access network.

[0122] Step 502: During the initial access process of the terminal, the terminal sends a connection establishment request to the network side, and the connection establishment request carries the identifier of the network slice requesting access.

[0123] Step 503: the base station receives the connection establishment request of the terminal, and sends the connection establishment req...

Abstract

The present invention discloses a network slice selection method, apparatus and system. The invention aims to solve a network slice selection problem in a process where a terminal is connected into a 5G network. The invention includes the following steps that: a control plane function entity receives the connection establishment request of the terminal; and the control plane function entity selects a network slice from at least one network slice configured by the network side for the terminal according to the connection establishment request.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network slice selection method, device and system. Background technique [0002] In the fifth-generation mobile communication (referred to as 5G) network, a physical network is divided into multiple virtual logical networks, and each logical network corresponds to a different application scenario. The logical network is called network slicing. For example, network slicing can be defined according to user needs, such as network slicing for high-definition video communication, network slicing for mobile phone communication, network slicing for massive Internet of Things, etc. [0003] figure 1 It is a schematic diagram of an existing long term evolution (Long Term Evolution, LTE) radio access network system architecture. In the existing LTE network, logical functions and physical entities are tightly coupled. One physical entity is only used to implement one logi...
