Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell residence method, a terminal, and a network device.
Background
In the prior art, a terminal in an idle state or a deactivated state selects a cell to camp on according to a frequency priority, and accesses the cell in a camping group. When the service transmission is finished and the service transmission returns to the idle state, the current flow is that the terminal selects a cell to reside, and if the TA (tracking area) of the resident cell is found to be changed, the terminal needs to initiate a registration flow again to perform TA update.
When initiating access, a terminal supporting multiple slices does not know what slice service the terminal is about to initiate, and if the network does not support the slice service initiated by the terminal at the moment, a switching process needs to be executed to switch to a cell supporting the slice service. And additional time delay is caused, and if the terminal can be resided in one cell according to the frequency priority, and other cells supporting the slice are selected for access according to the initiated service, the time delay is greatly reduced. However, another problem is also caused, when the terminal finishes the service and returns to the idle state, the terminal performs cell selection according to the existing flow, and if the terminal reselects a cell of a different TA, the terminal needs to re-register to perform TA update, and then the terminal selects the original cell according to the frequency priority, the terminal needs to re-register to perform TA update, which causes additional flow overhead. If the terminal can camp on the original cell again after the service is returned to the idle state, the above-mentioned procedure overhead is omitted.

Step 2, after initiating access, the network issues measurement configuration for the UE, wherein the measurement configuration comprises the frequency and PCI of the cell1, and meanwhile, the measurement configuration indicates the terminal to report slice information or TA information;

In another implementation example, the F1 frequency supports URLLC slices, the F2 frequency supports eMBB slices, and the UE supports URLLC and eMBB slices simultaneously.
Step 1, UE resides in a cell1 of F1, when eMBB service is initiated, access is directly initiated in a cell 2 of F2, and simultaneously a network is informed: access indication information, which indicates that the access is initiated by the terminal to the non-resident cell; PCI, frequency, TA list, supported slice (URLLC) of cell1 (formerly camped cell).

a) The terminal firstly confirms whether the cell1 meets the residence condition, and if so, the terminal directly resides in the cell 1; (ii) a
b) If the cell1 does not meet the residence condition, selecting the cell meeting the residence condition on the F1 for residence or selecting the cell supporting the same slice type as the cell1 for residence;
c) If the conditions are not met, selecting the cells, and selecting the cells meeting the residence conditions for residence;
and 3, if the terminal is in the third condition (c), the terminal needs to perform TA updating.
In another implementation example, the F1 frequency supports URLLC slices, the F2 frequency supports eMBB slices, and the UE supports URLLC and eMBB slices simultaneously.

Step 2, initiating fast access, completing service transmission in the cell 2, after connection release,
a) The terminal firstly confirms whether the cell1 meets the residence condition, and if so, the terminal directly resides in the cell 1; (ii) a
b) If the cell1 does not meet the residence condition, selecting the cell meeting the residence condition on the F1 for residence or selecting the cell supporting the same slice type as the cell1 for residence;
c) If the conditions are not met, selecting a cell, and selecting the cell meeting the residence condition for residence;
and 3, if the terminal is in the third situation (c), the terminal needs to perform TA updating.
