Abstract:
In a heterogeneous wireless network, connectivity is simultaneously available
using different radio networks with overlapping coverage areas. A mobile user
equipment with a multiple mode card that can work under various frequency bands
and modulation schemes can switch from one technology to another in order to
maintain communication. This procedure known as a vertical handover (VHO)
provides the
benefit of utilizing the higher bandwidth and lower cost of wide local area networks
as well as better mobility support and larger coverage of cellular networks. The
authors investigate details of the VHO procedure from WLAN (Wireless Local
Area Network) to the
3GPP Long Term Evolution (LTE). The VHO procedure includes 40 signaling
messages, which are responsible for authorization and resource allocation in the
target LTE network. The authors analyze the VHO sojourn time and its 95 percent
quantile using a multiphase queuing system with background traffic.
