Mitigating the Signaling Resources Expended in 5G Location Management Procedures at Millimeter-Wave Frequencies
The signaling resources expended
and the power consumed by User Equipments
(UEs) in the Location Management (LM) procedures
are expected to be higher in Fifth Generation (5G)
than in legacy wireless communications networks.
To mitigate this challenge, this work proposes a hybrid
scheme that mitigates the signaling resources expended
in paging and RAN-based Notification Area Update
(RNAU) procedures in 5G. The approach utilizes
a hybrid scheme that embeds a UE Identifier (UEID)
partitioning scheme that directional pages UEs into
a gNB-based UE Mobility Tracking (UEMT) scheme.
The approach configures a gNB in an RRC_Inactive
state to beam sweep a UEs last registered cell area
before directionally paging the UE. The approach
proposed in this work is implemented on a modified
network architecture to reduce the signaling resources
expended on both paging and RNAU of UEs at higher
frequencies which is an enabling factor for mmWave
systems. Simulation results of the total accumu-
lated cost of paging showed a 65.13 % and 8.69 %
reduction in signaling resources expended against
the conventional approach and the existing gNB-based
UEMT approach, respectively. Additionally, the total
accumulated resources expended in both procedures
over 24 hours showed that the modified gNB-based
UEMT scheme outperformed the conventional scheme
and the gNB-based UEMT scheme by 90.96 %
and 38.36 %, respectively
