Abstrakt

This paper investigates the potentials of traffic
steering in the Radio Resource Control (RRC) Idle state by
evaluating the Absolute Priorities (AP) framework in a multilayer
Long Term Evolution (LTE) macrocell scenario. Frequency
priorities are broadcast on the system information and RRC Idle
users can be steered towards higher priority carriers whenever
coverage allows it. However, such an approach may overload the
prioritized layers. For that purpose, an enhanced scheme is
proposed, where priorities are adjusted on a user basis and are
provided to the terminal via the connection release signaling. The
priority adjustment is based on both the Composite Available
Capacity (CAC) and the radio conditions of the candidate layers.
Compared to broadcast AP, the proposed scheme achieves better
load balancing performance and improves network capacity,
given that the User Equipment (UE) inactivity periods are not
significantly long. Finally, better alignment between the RRC
Connected and Idle mobility procedures is observed, guarantying
significant decrease of handovers/reselections and potential
battery life savings by minimizing the Inter-Frequency (IF)
measurement rate in the RRC Idle.
