Selective joinder of user equipment with wireless cell
View Patent ↗Embodiments are described herein for selective joinder, by a user equipment (“UE”), to a wireless cell of a plurality of wireless cells. In various embodiments, this may include transitioning, by the UE, from an idle mode to a connected mode, and contemporaneously with the transition of the UE from the idle mode to the connected mode, measuring, by the UE, signals of a first plurality of cells. In various embodiments, the UE may identify, from within the first plurality of cells, a second plurality of cells having measured signals that satisfy a channel condition criterion and frequency priorities that satisfy a priority criterion. In various embodiments, the UE may be configured to select and join a cell of the second plurality of cells, randomly or based on respective loads of the second plurality of cells.
1. A user equipment (“UE”) comprising:
radio resource control (“RRC”) circuitry to transition the UE from an RRC idle mode to an RRC connected mode; and
load balancing circuitry coupled to the RRC circuitry to:
measure signals of a first plurality of cells;
identify, from within the first plurality of cells, a second plurality of cells having measured signals that satisfy a channel condition criterion and priorities that satisfy a priority criterion; and
select a cell of the second plurality of cells to join.
2. The UE of claim 1 , wherein the load balancing circuitry is to select the cell from the second plurality of cells based on an instruction received via network signaling.
3. The UE of claim 2 , wherein the load balancing circuitry is to select the cell from the second plurality of cells randomly or based on a load of the cell, responsive to the instruction.
4. The UE of claim 2 , wherein the instruction comprises a positive integer m, and the load balancing circuitry is further to select the cell from m selected cells of the second plurality of cells.
5. The UE of claim 4 , wherein the m selected cells are selected from the second plurality of cells based on their channel conditions or loads.
6. The UE of claim 1 wherein the load balancing circuitry is further to randomly select the cell from the second plurality of cells.
7. The UE of claim 1 , wherein the load balancing circuitry is to select the cell from the second plurality of cells based on a load of the cell.
8. The UE of claim 1 , wherein the channel condition criterion is satisfied by a cell when a measured signal of the cell has a channel condition measurement that exceeds a threshold channel condition measurement.
9. The UE of claim 1 , wherein the priority criterion is satisfied by a cell when the cell is associated with a priority that is greater than or equal to all other priorities of the first plurality of cells.
10. The UE of claim 1 , wherein the priority criterion is satisfied by a cell when the cell is associated with a priority that is greater than a threshold priority.
11. The UE of claim 1 , wherein the load balancing circuitry is to save priorities received via dedicated signaling during an RRC Connection Release.
12. The UE of claim 11 , wherein the load balancing circuitry is further to selectively join the cell of the second plurality of cells based on the saved priorities.
13. A computer-implemented method, comprising:
transitioning, by a user equipment (“UE”), from an idle mode to a connected mode;
measuring, by the UE, signals of a first plurality of cells
identifying, by the UE from within the first plurality of cells, a second plurality of cells having measured signals that satisfy a channel condition criterion and priorities that satisfy a priority criterion; and
selecting, by the UE, a cell of the second plurality of cells to join, randomly or based on respective loads of the second plurality of cells.
14. The computer-implemented method of claim 13 , further comprising:
receiving, by the UE via radio resource control (“RRC”) or non-access stratum (“NAS”) signaling, an instruction; and
selecting, by the UE, the cell from the second plurality of cells based on the instruction.
15. The computer-implemented method of claim 14 , further comprising selecting, by the UE, the cell from the second plurality of cells randomly or based on a load of the cell, responsive to the instruction.
16. The computer-implemented method of claim 14 , wherein the instruction comprises a positive integer m, and the method further comprises selecting, by the UE, the cell from m selected cells of the second plurality of cells.
17. The computer-implemented method of claim 16 , wherein the m selected cells are selected from the second plurality of cells based on their channel conditions or loads.
18. The computer-implemented method of claim 13 , further comprising randomly selecting, by the UE, the cell from the second plurality of cells.
19. The computer-implemented method of claim 13 , further comprising selecting, by the UE, the cell from the second plurality of cells based on a load of the cell.
20. The computer-implemented method of claim 13 , further comprising saving priorities received via dedicated signaling during an RRC Connection Release.
21. The computer-implemented method of claim 13 , further comprising selectively joining the cell of the second plurality of cells based on the saved priorities.
