Oksijen
USSD Gateway
Oksijen
USSD Gateway enables mobile operators to offer
various call related services, value added services
and customer care services using USSD (Unstructured
Supplementary Service Data) technology as data
bearer. It allows sending and receiving information
messages over GSM radio signaling channels.
Due
to the simplicity of service usage and network
cost efficiency, USSD has become more popular
in recent years and created an alternative way
to SMS, IVR, WAP and SIM tool kit based services.
USSD service
users do not need to access any phone specific
menu; they simply enter the required USSD command
by dialing service digits. USSD commands are
then routed the home mobile network’s
HLR, which allows users to access these services
and while they are roaming in the same way as
in home network.
Once the
user accesses a USSD application, a session
is established in the Oksijen USSD Gateway and
this session remains open until it is terminated
by the user or application side. This allows
real-time fast and interactive messaging communication
between user and USSD application.
USSD can
be easily utilized for simple customer care
services. It is more efficient than IVR solutions
as it does not occupy voice channels. It is
also a fast and user-friendly alternative for
WAP for simple content delivery and information
services. In order to be able to deliver content
services over WAP, there is a need for immense
effort for WAP development. However, USSD services
require less effort for service creation. In
addition, USSD services can be accessed faster
through the USSD menu compared to browsers based
on the SIM tool kit applications. As the menus
are dynamic, there is no need to reconfigure
subscriber’s SIM cards.

Customer Care and Support Services:
For simple
customer care and support services, USSD
might fit better than IVR
solutions. IVR systems are inconvenient
as it takes too much time to deal with
simple requests and as they use expensive
voice channels.
USSD menu browsing can be an ideal alternative
for operators to gain operational
efficiency in their customer services
with subscribers able to resolve day-to-day
requests themselves.
