Abstract
Provision of multimedia services with high bandwidth
demands is constantly increasing its share in mobile systems.
Aiming a more efficient distribution of multicast/broadcast
contents in the UMTS networks, 3GPP introduced the
Multimedia Broadcast Multicast Service (MBMS). Even
though this technology brought significant improvements
regarding the network efficiency, the UTRAN (UMTS
Terrestrial Radio Access Network) remains the network’s
most vulnerable area due to its shortage resources. The
integration of wireless LAN (WLAN) access technology in
cellular data networks to enhance their services coverage and
increase data rates, is an extremely interesting solution for
operators. In addition, this solution based on WLAN is easily
deployed and can provide additional license-free bandwidth.
Therefore, this paper addresses a possible WLAN integration,
which uses a UMTS Access Point (UAP) that establishes a
WLAN tunnel to provide MBMS data services to UEs with
both UMTS and WLAN interfaces. Using this simulation
environment, we pretend to measure and conclude about the
benefits achieved from merging these two access technologies
when delivering MBMS services.
