Abstract
Methods and systems are described for deriving slice-based reselection priorities. Embodiments can select a frequency that supports one or more network slices. Methods can include obtaining reselection priorities for each frequency on which a user equipment may camp, obtaining a slice priority for one or more prioritized slices and deriving slice-based reselection priorities for all frequencies with reselection priorities. A cell search can then be performed according to the slice-based reselection priorities.
Claims20
A method performed by a user equipment (UE) (2200) for deriving slice-based reselection priorities for selecting a frequency that supports one or more network slices, the method comprising:
- obtaining one or more reselection priorities for each frequency on which the UE may camp (710);
- obtaining a slice priority for one or more prioritized slices (720);
- deriving slice-based reselection priorities for the frequencies having the reselection priorities (730);
- and
- performing cell search according to the derived slice-based reselection priorities (740).
A method performed by a network (1106) for providing data to a UE for deriving slice-based reselection priorities for selecting a frequency that supports one or more network slices, the method comprising:
- transmitting, to the UE, a slice priority for one or more prioritized slices (810);
- transmitting, to the UE, one or more reselection priorities for each frequency on which the UE may camp (820);
- transmitting, to the UE, one or more slice-specific reselection priorities configured to be combined with the slice priority and the reselection priorities to derive slice-based reselection priorities for the frequencies on which the UE may camp (830);
- and
- receiving a cell selection from the UE indicative of a target cell on which the UE chooses to camp based on the derived slice-based reselection priorities (840).
