network and vice versa, as well as traffic
measurements within the cellular network.
As from February 5, these tests
were followed up by daily meetings,
where the latest findings as well as possible
improvements were discussed and
analyzed.
Looking back at this activity, we can
conclude that the quality project by its
intense checking activity, succeeded in
maintaining the NMT-900 network close
to its optimum shape, contributing to
reasonably good degree of service even
during periods of heavy traffic demand.
7 Operation during the
Olympic Games
By signing the contract with TOP, Telemobil
accepted to participate with qualified
personnel in the Olympic Network
Operations Centre (NOC). By being collocated
with personnel responsible for
other parts of the telecommunication networks,
Tele-mobil had a good opportunity
to be quickly updated regarding possible
network problems.
As NMT-900 had been deemed the main
traffic machine of cellular services, the
attention was focused on this service
together with the alphanumeric paging
system, which was also part of the contract
with LOOC.

At the NOC, Tele-mobil installed terminals
for monitoring and operation of all
the cellular services as well as the
alphanumeric paging system within the
Olympic area. For NMT and GSM,
advanced control systems were used; as
for the alphanumeric paging system, a
standard terminal was connected to the
paging controller in Trondheim.
This centre was attended continuously by
one of four experienced engineers from
Tele-mobil. In addition, Tele-mobils
regional Mobile Network Control Centre
in Hamar was attended from 0600 hours
until 2200 hours throughout the week.
Two experienced engineers were added
to the 5 engineers usually operating at
this centre. The corresponding centre in
Oslo as well as the paging controller in
Trondheim, was also attended for the
same period every day, but without additional
engineers.
Tele-mobils centre for subscriber services
(164) was attended 24 hours a day,
being able to clarify all questions regarding
subscription at any time.
All NMT-900 base stations within the
Olympic area were monitored 24 hours a
day from NOC. This centre also took
over the monitoring of the NMT- and
GSM-networks for the centres in Hamar
and Oslo, as well as the paging controller
in Trondheim for the period 2200 till
0600.
The Tele-mobil engineers at NOC also
had the possibility to call out engineers
for service at the radio base stations within
the Olympic area 24 hours a day.
