Method for indicating slice information, terminal device and network device
View Patent ↗A method for indicating slice information, a terminal device and a network device are provided. The method for indicating slice information includes: receiving first slice information from a network device. The first slice information includes at least one of: at least one first slice identification or at least one piece of first frequency point information.
1 . A method for indicating slice information, comprising:
receiving first slice information from a network device, wherein the first slice information comprises a plurality of first slice identifications, wherein a sequence of a plurality of frequency points corresponding to the plurality of first slice identifications is in a one-to-one correspondence with a sequence of a plurality of frequency points in a first specific system information block (SIB), and the first specific SIB is an SIB4.
2 . The method of claim 1 , wherein
each of the plurality of first slice identifications is an identification of a slice; or
each of the plurality of first slice identifications is an identification of a group of slices.
3 . The method of claim 1 , wherein
a slice identification is indicated by a slice index; or
a group of slice identifications is indicated by a slice index; or
a group of slice identifications is indicated by a slice group index.
4 . The method of claim 3 , further comprising:
obtaining a correspondence between the slice identification and the slice index.
5 . The method of claim 4 , wherein the correspondence is indicated by a non-access stratum (NAS) message.
6 . The method of claim 1 , wherein
the first slice information is carried in at least one of: a first SIB, a dedicated radio resource control (RRC) message or an NAS message, and
the first SIB is a second specific SIB, and the second specific SIB is at least one SIB newly added in a protocol.
7 . The method of claim 1 , further comprising:
performing a random access process according to the first slice information; or
performing a cell access or a cell reselection according to the first slice information.
8 . A terminal device, comprising:
a processor; and
a memory for storing a computer program executable by the processor,
wherein the processor is configured to execute the computer program to:
receive first slice information from a network device, wherein the first slice information comprises a plurality of first slice identifications, wherein a sequence of a plurality of frequency points corresponding to the plurality of first slice identifications is in a one-to-one correspondence with a sequence of a plurality of frequency points in a first specific system information block (SIB), and the first specific SIB is an SIB4.
9 . A network device comprising:
a processor; and
a memory for storing a computer program executable by the processor,
wherein the processor is configured to execute the computer program to:
transmit first slice information to a terminal device, wherein the first slice information comprises a plurality of first slice identifications, wherein a sequence of a plurality of frequency points corresponding to the plurality of first slice identifications is in a one-to-one correspondence with a sequence of a plurality of frequency points in a first specific system information block (SIB), and the first specific SIB is an SIB4.
10 . The network device of claim 9 , wherein
each of the plurality of first slice identifications is an identification of a slice; or
each of the plurality of first slice identifications is an identification of a group of slices.
11 . The method of claim 1 , wherein
frequency point information of the plurality of frequency points corresponding to the plurality of first slice identifications comprises a frequency point priority.
12 . The method of claim 1 , wherein the plurality of frequency points in the SIB4 are indicated before the plurality of first slice identifications are indicated in the first slice information.
13 . The terminal device of claim 8 , wherein
each of the plurality of first slice identifications is an identification of a slice; or
each of the plurality of first slice identifications is an identification of a group of slices.
14 . The terminal device of claim 8 , wherein
a slice identification is indicated by a slice index; or
a group of slice identifications is indicated by a slice index; or
a group of slice identifications is indicated by a slice group index.
15 . The terminal device of claim 8 , wherein frequency point information of the plurality of frequency points corresponding to the plurality of first slice identifications comprises a frequency point priority.
16 . The terminal device of claim 8 , wherein the plurality of frequency points in the SIB4 are indicated before the plurality of first slice identifications are indicated in the first slice information.
17 . The terminal device of claim 8 , wherein
the first slice information is carried in at least one of: a first SIB, a dedicated radio resource control (RRC) message or an NAS message, and
the first SIB is a second specific SIB, and the second specific SIB is at least one SIB newly added in a protocol.
18 . The terminal device of claim 8 , wherein the processor is further configured to execute the computer program to:
perform a random access process according to the first slice information; or
perform a cell access or a cell reselection according to the first slice information.
19 . The network device of claim 9 , wherein frequency point information of the plurality of frequency points corresponding to the plurality of first slice identifications comprises a frequency point priority.
20 . The network device of claim 9 , wherein the plurality of frequency points in the SIB4 are indicated before the plurality of first slice identifications are indicated in the first slice information.
