Abstract

Embodiments of the present disclosure provide a cell reselection method. The method includes: receiving, by a terminal device, cell information of a plurality of cells and a model supported by each cell from a first network device; determining, by the terminal device, a first cell from the plurality of cells according to the cell information and the model supported by each cell; and reselecting, by the terminal device, the first cell.

First claim

1 . A cell reselection method, comprising:
receiving, by a terminal device, cell information of a plurality of cells and a model supported by each cell from a first network device; determining, by the terminal device, a first cell from the plurality of cells according to the cell information and the model supported by each cell; and reselecting, by the terminal device, the first cell.

2 . The method of claim 1 , wherein the receiving cell information of a plurality of cells and a model supported by each cell from a first network device comprises:
receiving a broadcast message from the first network device, wherein the broadcast message comprises the cell information and the model supported by each cell; wherein the broadcast message is System Information Block (SIB) signaling or a paging message.

3 . (canceled)

4 . The method of claim 1 , wherein the cell information comprises a frequency of the cell and an identifier of the cell.

5 . The method of claim 1 , wherein the cell information comprises the frequency of the cell, and the determining a first cell from the plurality of cells according to the cell information and the model supported by each cell comprises:
receiving a cell reselection frequency priority from the first network device; and determining the first cell from the plurality of cells according to the cell reselection frequency priority, a frequency of each of the plurality of cells, and the model supported by each cell.

6 . The method of claim 5 , wherein the determining the first cell from the plurality of cells according to the cell reselection frequency priority, a frequency of each of the plurality of cells, and the model supported by each cell comprises:
determining a model list of interest of the terminal device, wherein the model list comprises one or more first models; and determining the first cell from the plurality of cells according to the cell reselection frequency priority, the frequency of each of the plurality of cells, the model supported by each cell, and the model list.

7 . The method of claim 6 , wherein the determining the first cell from the plurality of cells according to the cell reselection frequency priority, the frequency of each of the plurality of cells, the model supported by each cell, and the model list comprises:
determining whether there is at least one second cell according to the model supported by each cell, wherein the model supported by the second cell comprises all of the first models; in a condition that there is at least one second cell, determining the first cell according to the frequency of each second cell and the cell reselection frequency priority; and in a condition that there is no second cell, determining the first cell from the plurality of cells according to the model supported by each cell and the model list.

8 . The method of claim 7 , wherein the determining the first cell according to the frequency of each second cell and the cell reselection frequency priority comprises:
determining a first frequency of a top priority from the frequency of each second cell according to the cell reselection frequency priority; obtaining a first measurement result of the second cell whose frequency is the first frequency; and determining the first cell according to the first measurement result.

9 . The method of claim 7 , wherein the determining the first cell from the plurality of cells according to the model supported by each cell and the model list comprises:
determining, in a condition that there is a third cell in the plurality of cells, the first cell from the third cell, wherein the model supported by each third cell comprises at least one first model; and in a condition that there is no third cell in the plurality of cells, obtaining a second measurement result of the plurality of cells, and determining the first cell according to the second measurement result.

10 . The method of claim 9 , wherein the determining, in a condition that there is a third cell in the plurality of cells, the first cell from the third cell comprises:
determining a fourth cell from the third cell according to a first model priority in the model list, wherein the model supported by the fourth cell comprises the first model of a top priority in the first model supported by each third cell, and a frequency of a top cell reselection frequency priority in the frequency of each fourth cell is a second frequency; obtaining a third measurement result of the fourth cell whose frequency is the second frequency; and determining the first cell according to the third measurement result.

11 . The method of claim 5 , wherein for any first model, the method further comprises:
obtaining model information of the model supported by each cell; and determining whether the model supported by each cell comprises the first model according to the model information; wherein the model information comprises at least one of the following information: a type of the model; an application type of the model; an application scenario of the model; a size of the model; accuracy of the model; and an index of the model.

12 - 21 . (canceled)

22 . A terminal device, comprising at least one processor and a memory, wherein
the memory stores a computer-executable instruction; and the at least one processor executes the computer-executable instruction stored in the memory to enable the at least one processor to: receive cell information of a plurality of cells and a model supported by each cell from a first network device; determine a first cell from the plurality of cells according to the cell information and the model supported by each cell; and reselect the first cell.

23 . (canceled)

24 . A non-transitory computer-readable storage medium, storing a computer-executable instruction, a processor, when executing the computer-executable instruction, is configured to:
receive cell information of a plurality of cells and a model supported by each cell from a first network device; determine a first cell from the plurality of cells according to the cell information and the model supported by each cell; and reselect the first cell.

25 . The terminal device of claim 22 , wherein the at least one processor executes the computer-executable instruction stored in the memory to enable the at least one processor to:
receive a broadcast message from the first network device, wherein the broadcast message comprises the cell information and the model supported by each cell; wherein the broadcast message is System Information Block (SIB) signaling or a paging message.

26 . The terminal device of claim 22 , wherein the cell information comprises a frequency of the cell and an identifier of the cell.

27 . The terminal device of claim 22 , wherein the at least one processor executes the computer-executable instruction stored in the memory to enable the at least one processor to:
receive a cell reselection frequency priority from the first network device; and determine the first cell from the plurality of cells according to the cell reselection frequency priority, a frequency of each of the plurality of cells, and the model supported by each cell.

28 . The terminal device of claim 27 , wherein the at least one processor executes the computer-executable instruction stored in the memory to enable the at least one processor to:
