Abstract
Embodiments of the disclosure discloses a method for network slice-based cell determination and related products. The method includes the following. A terminal device determines at least one first network slice. The terminal device determines a first cell to be accessed according to the at least one first network slice.
Claims18
A method for network slice-based cell determination, comprising:
- determining, by a terminal device, at least one first network slice;
- and
- determining, by the terminal device, a first cell to be accessed according to the at least one first network slice, wherein:
- determining, by the terminal device, the first cell to be accessed according to the at least one first network slice comprises:
- transmitting, by a non-access stratum (NAS) layer of the terminal device, indication information corresponding to the at least one first network slice to an access stratum (AS) layer;
- performing, by the AS layer of the terminal device, cell search according to the indication information to obtain a first search result;
- determining, by the AS layer of the terminal device, the first cell according to the first search result and feeding back the first cell to the NAS layer;
- and
- determining, by the NAS layer of the terminal device, the first cell as a cell to be accessed, wherein after performing, by the AS layer of the terminal device, the cell search according to the indication information, the method further comprises:
- feeding back, by the AS layer of the terminal device, a second search result of the cell search to the NAS layer, wherein the second search result is that no cell satisfying the indication information is found.
7 more elements
A terminal device, comprising:
- a memory configured to store computer programs;
- and
- a processor configured to execute the computer programs stored in the memory to cause the terminal device to:
- determine at least one first network slice;
- and
- determine a first cell to be accessed according to the at least one first network slice, wherein:
- determining the first cell to be accessed according to the at least one first network slice comprises:
- transmitting, by a non-access stratum (NAS) layer of the terminal device, indication information corresponding to the at least one first network slice to an access stratum (AS) layer;
- performing, by the AS layer of the terminal device, cell search according to the indication information to obtain a first search result;
- determining, by the AS layer of the terminal device, the first cell according to the first search result and feeding back the first cell to the NAS layer;
- and
- determining, by the NAS layer of the terminal device, the first cell as a cell to be accessed, wherein after performing, by the AS layer of the terminal device, the cell search according to the indication information, the processor is further configured to cause the terminal device to:
- feed back, by the AS layer of the terminal device, a second search result of the cell search to the NAS layer, wherein the second search result is that no cell satisfying the indication information is found.
10 more elements
A network device, comprising:
- a memory configured to store computer programs;
- and
- a processor configured to execute the computer programs stored in the memory to cause the network device to:
- transmit first information to a terminal device when receiving a first message, wherein the first information comprises at least one piece of network slice information, the network slice information is used for the terminal device to determine at least one first network slice and determine a first cell to be accessed according to the at least one first network slice, and the first message is a location update message or a configuration update message initiated by the terminal device, wherein:
- the network slice information is used for the terminal device to determine the first cell to be accessed according to the at least one first network slice by:
- transmitting, by a non-access stratum (NAS) layer of the terminal device, indication information corresponding to the at least one first network slice to an access stratum (AS) layer;
- performing, by the AS layer of the terminal device, cell search according to the indication information to obtain a first search result;
- determining, by the AS layer of the terminal device, the first cell according to the first search result and feeding back the first cell to the NAS layer;
- and
- determining, by the NAS layer of the terminal device, the first cell as a cell to be accessed, wherein after performing, by the AS layer of the terminal device, the cell search according to the indication information, the network slice information is further used for the terminal device to:
- feed back, by the AS layer of the terminal device, a second search result of the cell search to the NAS layer, wherein the second search result is that no cell satisfying the indication information is found.
