Abstract— 3GPP standards release 8 and 9 have introduced
Long Term Evolution (LTE) Radio Access Technology (RAT)
to provide broadband services to end users. LTE is an all-IP
packet switched technology. The evolution path towards LTE
can be done in two ways. First, for GSM only operators,
internetworking between GSM networks and LTE is
envisioned to go through IP Multimedia Subsystem (IMS).
Second, for 3G/3.5G operators the internetworking can be
utilized through Packet Data Network Gateway (P-GW). LTE
deployment and internetworking with the existing GSM/EDGE
Radio Access Technology (GERAN) and / or UMTS Terrestrial
Radio Access Networks (UTRAN) will bring out several
technical issues. First, internetworking between GERAN and
LTE will highlight the control of voice calls over IP networks.
However, most operators agreed to support VoLTE. Second,
LTE will be deployed in the same frequency band as of
GERAN/UTRAN which will cause signalling problems. In this
paper, first, based on service requests, we propose an
algorithm to optimize the available network resources in multi
radio deployment. Second, single radio IMS enhanced user
equipment is modelled, and finally, a voice call continuity
study will be conducted through a Discrete Event Simulator
(DES) based on multi service environment.
Index Terms— Inter-Networking, GERAN, LTE, UTRAN,
