Abstract
Systems, methods, and software of managing bandwidth allocated to User Equipment (UE). In one embodiment, a bandwidth management system collects cell load information for a plurality of cells within a Radio Access Network (RAN), and processes the cell load information to determine a cell load status for each of the cells. The system performs bandwidth throttling for the UE by determining a location of the UE, identifying the cell load status for one or more cells in a region of the RAN corresponding with the location of the UE, determining whether the region of the RAN is overloaded based on the cell load status, and controlling a downgrade of bandwidth allocated to the UE in the RAN responsive to a determination that the region is overloaded.
Claims20
A bandwidth management system comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor cause the bandwidth management system at least to:
- collect cell load information for a plurality of cells within a Radio Access Network (RAN);
- process the cell load information to determine a cell load status for each of the cells;
- and
- perform bandwidth throttling by:
- receiving a message regarding User Equipment (UE) of a user of the RAN:
- determining a location of the UE;
- identifying a region of interest corresponding with the location of the UE that includes multiple cells of the RAN;
- identifying the cell load status for each of the cells in the region of interest;
- determining that the region of interest is overloaded when a threshold number of the cells in the region of interest are overloaded based on the cell load status for the cells in the region of interest;
- and
- controlling a downgrade of bandwidth allocated to the UE when the region of interest is overloaded.
A method of managing bandwidth within a Radio Access Network (RAN), the method comprising:
- collecting cell load information for a plurality of cells within the RAN;
- processing the cell load information to determine a cell load status for each of the cells;
- and
- performing bandwidth throttling by:
- receiving a message regarding User Equipment (UE) of a user of the RAN;
- determining a location of the UE;
- identifying a region of interest corresponding with the location of the UE that includes multiple cells of the RAN;
- identifying the cell load status for each of the cells in the region of interest;
- determining that the region of interest is overloaded when a threshold number of the cells in the region of interest are overloaded based on the cell load status for the cells in the region of interest;
- and
- controlling a downgrade of bandwidth allocated to the UE when the region of interest is overloaded.
A non-transitory computer readable medium embodying programmed instructions executed by a processor, wherein the instructions direct the processor to implement a method of managing bandwidth within a Radio Access Network (RAN), the method comprising:
- collecting cell load information for a plurality of cells within the RAN;
- processing the cell load information to determine a cell load status for each of the cells;
- and
- performing bandwidth throttling by:
- receiving a message regarding User Equipment (UE) of a user of the RAN;
- determining a location of the UE;
- identifying a region of interest corresponding with the location of the UE that includes multiple cells of the RAN;
- identifying the cell load status for each of the cells in the region of interest;
- determining that the region of interest is overloaded when a threshold number of the cells in the region of interest are overloaded based on the cell load status for of the cells in the region of interest;
- and
- controlling a downgrade of bandwidth allocated to the UE when the region of interest is overloaded.
