Abstract

Various embodiments herein disclose a method camping a User Equipment (UE) on a cell, the method comprising: creating a combined Most Recently Used (MRU) list by merging a list 4G MRU frequencies with a Public Land Mobile Network (PLMN) having a 5GC and a list of 5G MRU frequencies, determining whether one of a 4G cell with 5G core (5GC) and a 5G cell is available for camping by performing a MRU scan on the combined MRU list; performing one of: camping on one of the 4G cell with 5G core and the 5G cell in response to determining that one of the 5G cell and the 4G cell with 5G core is available and performing a 4G MRU frequency scan on a list of 4G without 5GC MRU frequencies in response to determining that one of the 4G cell with 5G core and the 5G cell is not available.

Claims15

Dependent claims

A method of camping a user equipment (UE) on a cell, based the UE being present in overlapping 5th generation (5G) and 4th generation (4G) areas, the method comprising:

creating, by the UE, a combined most recently used (MRU) list by merging a list of 4G MRU frequencies having a 5G core (5GC) and a list of 5G MRU frequencies;
determining, by the UE, whether one of a 4G cell with 5G core and a 5G cell is available for camping the UE by performing a MRU scan on the combined MRU list;
and
performing, by the UE, at least one of:
camping on one of the 4G cell with 5G core (5GC) and the 5G cell in response to determining that one of the 5G cell and the 4G cell with 5G core is available for camping the UE based on the MRU scan on the combined MRU list, and
performing a 4G MRU frequency scan on a list of 4G MRU frequencies without 5GC in response to determining that one of the 4G cell with 5G core and the 5G cell is not available for camping the UE based on the MRU scan on the combined MRU list, and camping the UE based on the 4G MRU frequency scan.

3 more elements

A user equipment (UE) configured to be camped on a cell, based on the UE being present in a 5th generation (5G) and a 4th generation (4G) overlapping area, the UE comprising:

a memory;
a processor coupled to a communicator comprising communication circuitry, the processor and configured to control the UE to:
create a combined most recently used (MRU) list by merging a list 4G MRU frequencies with a public land mobile network (PLMN) having a 5G core (5GC) and a list of 5G MRU frequencies;
determine whether one of a 4G cell with 5GC and a 5G cell is available for camping the UE by performing a MRU scan on the combined MRU list;
perform at least one of:
camping the UE on one of the 4G cell with 5GC and the 5G cell in response to determining that one of the 5G cell and the 4G cell with 5GC is available for camping the UE based on the MRU scan on the combined MRU list, and
performing a 4G MRU frequency scan on a list of 4G without 5GC MRU frequencies in response to determining that one of the 4G cell with 5GC and the 5G cell is not available for camping the UE based on the MRU scan on the combined MRU list, and camping the UE based on the 4G MRU frequency scan.
