Embodiment 2

[0089] like image 3 As shown, this embodiment provides a method for updating slice identifiers, including:

[0090] Step S210: Receive the control plane instruction carrying the currently available slice ID sent by the access network element; wherein, the slice ID is the identifier of the network slice; the control plane signaling is used to control the terminal to execute corresponding Operational control instructions;

[0091] Step S220: Update the slice ID stored in the slice configuration server according to the currently available slice ID. In a specific implementation, the method may further include: Step S230. The step S230 may include: responding to the control plane instruction based on the currently available slice ID.

[0092]The method described in this embodiment is a slice identifier updating method applied in a terminal. In this embodiment, the terminal receives the currently available slice ID by receiving the control plane network element, updates the sli...

Embodiment 3

[0104] like image 3 As shown, this embodiment provides a method for updating slice identifiers, including:

[0105] Step S310: When it is determined that the slice identification ID authorized by the terminal has changed, update the currently available slice ID stored in the subscription database; wherein, the slice ID is an identification of a network slice;

[0106] Step S320: Provide the currently available slice ID to the terminal; wherein, the currently available slice ID is used to be carried by an access network element and sent to the terminal in a control plane network element.

[0107] The slice identifier update method described in this embodiment may be a method applied to a subscription database. The subscription database jointly stores the subscription information of the terminal and the slice ID authorized to be used by the terminal, so as to facilitate information sharing in the communication network.

[0108] In this embodiment, when it is found that the sl...

Embodiment 4

[0117] like Figure 4 As shown, this embodiment provides a method for updating slice identifiers, including:

[0118] Step S410: Receive the currently available slice ID of the terminal from the subscription database; wherein, the slice ID is an ID of a network slice;

[0119] Step S420: Update the slice ID stored in the slice configuration server according to the currently available slice ID; wherein the stored currently available slice ID is used to send to the terminal through the access network element.

[0120] The slice identifier updating method provided in this embodiment may be a method applied in a slice configuration server. The step S410 may be to receive the currently available slice ID of the terminal from the subscription database, and update the slice ID stored in the slice configuration server, so as to improve update efficiency when the terminal initiates a slice ID update process.

[0121] The step S410 may include multiple implementations, two of which ar...

Abstract

The embodiments of the present invention disclose a network slice identifier update method. The method includes the following steps that: a slice ID (identifier) stored in a terminal is required to be updated, a slice ID which is currently available to the terminal and is provided by a storage network element are received, wherein the slice ID is the identifier of a network slice; and a control plane signal carrying the currently available slice ID is sent to the terminal, wherein the control plane signal is a control instruction for controlling the terminal to perform corresponding operation. The slice ID (identifier) stored in the terminal is updated through the control plane instruction, and therefore, on the one hand, dynamic update can be realized, and on the other hand, a special client is not required to be installed. The embodiments of the invention also disclose a network element and a terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for updating a slice identifier, a network element and a terminal. Background technique [0002] Network slicing (Network Slicing, NS) is to form a logically independent virtual network structure through the combination of network functions. An identifier (Identity, ID) of a network slice may be referred to as a slice ID for short. [0003] The application scenario of the slice ID may include: when the terminal accesses the network, the slice ID is carried in the initial access message, and the network side performs authentication based on the slice ID and other information to determine whether to allow the terminal to access. The terminal can determine the slices of the network slices that can be accessed by obtaining the corresponding slice IDs. The methods for the terminal to obtain the slice ID generally include the following two methods: [0004] The...
