Abstract

An information sending method includes: determining related information of a slice supported by a cell; and sending the related information to a non-access stratum by means of an access stratum.

Claims (78)

1 . An information sending method, performed by a terminal, and comprising:

determining related information of a slice supported by a cell; and

sending the related information to a non-access stratum by means of an access stratum,

wherein the related information comprises a priority of the slice,

wherein the priority of the slice is determined based on a quantity of cells supporting the slice, and

wherein the non-access stratum is configured to indicate a slice with a high priority to the access stratum, and the access stratum is configured to access the cell based on the slice with the high priority.

2 . The information sending method according to claim 1 , wherein the slice comprises at least one of the following:

a slice supported by a cell where the terminal is currently located;

a remapping slice supported by the cell where the terminal is currently located;

a slice supported by a neighboring cell of the cell; or

a remapping slice supported by the neighboring cell of the cell.

3 . The information sending method according to claim 1 , wherein the related information further comprises at least one of the following:

an identifier of the slice;

an identifier of the cell supporting the slice;

signal quality of the cell supporting the slice; or

whether a network allows to access the slice.

4 . The information sending method according to claim 3 , wherein the priority of the slice is further determined based on at least one of the following:

an indication of a base station; or

signal quality of the cell supporting the slice.

5 . The information sending method according to claim 1 , wherein sending the related information to the non-access stratum by means of the access stratum comprises:

sending, in response to determining an update of the related information, the related information to the non-access stratum by means of the access stratum.

6 . The information sending method according to claim 1 , wherein sending the related information to the non-access stratum by means of the access stratum comprises:

sending, in response to a terminal residing in a reselected cell after cell reselection, related information of a slice supported by the reselected cell to the non-access stratum by means of the access stratum.

7 . The information sending method according to claim 1 , further comprising:

determining an expected slice needed for the non-access stratum; and

the related information at least comprising: whether a suitable cell supporting the expected slice exists in a cell where a terminal is currently located and a neighboring cell of the cell.

8 . The information sending method according to claim 1 , further comprising:

determining an expected slice needed for the non-access stratum; and

sending the related information to the non-access stratum by means of the access stratum comprising:

sending, in response to inexistence of a suitable cell supporting the expected slice in a cell where a terminal is currently located and a neighboring cell of the cell, the related information to the non-access stratum by means of the access stratum.

9 . The information sending method according to claim 1 , further comprising:

determining an expected slice needed for the non-access stratum; and

sending the related information to the non-access stratum by means of the access stratum comprising:

sending, in response to existence of other alternative slices needed for the non- access stratum besides the expected slice, the related information to the non-access stratum by means of the access stratum.

10 . The information sending method according to claim 1 , further comprising:

determining an expected slice needed for the non-access stratum; and

sending the related information to the non-access stratum by means of the access stratum comprising:

sending related information of a suitable slice belonging to the expected slice in the slice to the non-access stratum by means of the access stratum.

11 . An information sending method, performed by a base station, and comprising:

sending related information of a slice supported by a cell corresponding to the base station to a terminal,

wherein the related information is sent to a non-access stratum of the terminal by an access stratum of the terminal, and the related information comprises a priority of the slice,

wherein the priority of the slice is determined based on a quantity of cells supporting the slice, and

12 . The information sending method according to claim 11 , further comprising:

sending indication information to the terminal to indicate the terminal to send the related information to the non-access stratum by means of the access stratum.

13 . A base station, comprising:

a processor; and

a memory configured to store a computer program, wherein

in response to determining that the computer program is executed by the processor, the computer program implements the information sending method according to claim 11 .

14 . A terminal, comprising:

a processor; and

a memory configured to store a computer program, wherein

in response to determining that the computer program is executed by the processor, the computer program implements:

determining related information of a slice supported by a cell; and

sending the related information to a non-access stratum by means of an access stratum,

wherein the related information comprises a priority of the slice,

wherein the priority of the slice is determined based on a quantity of cells supporting the slice, and

15 . The terminal according to claim 14 , wherein the slice comprises at least one of the following:

a slice supported by a cell where the terminal is currently located;

a remapping slice supported by the cell where the terminal is currently located;

a slice supported by a neighboring cell of the cell; or

a remapping slice supported by the neighboring cell of the cell.

16 . The terminal according to claim 14 , wherein the related information further comprises at least one of the following:

an identifier of the slice;

an identifier of the cell supporting the slice;

signal quality of the cell supporting the slice; or

whether a network allows to access the slice.

17 . The terminal according to claim 16 , wherein the priority of the slice is further determined based on at least one of the following:

an indication of a base station; or

signal quality of the cell supporting the slice.

18 . The terminal according to claim 14 , the computer program further implements:

sending, in response to determining an update of the related information, the related information to the non-access stratum by means of the access stratum.

19 . The terminal according to claim 14 , the computer program further implements:

20 . The terminal according to claim 14 , the computer program further implements:

determining an expected slice needed for the non-access stratum; and

the related information at least comprising: whether a suitable cell supporting the expected slice exists in a cell where a terminal is currently located and a neighboring cell of the cell.
