Mobile network failure a nuisance to users
(09/5/2000)

Nokia, whose slogan is "connecting people," Monday seemed to have
disconnected a host of fixed phone users from mobile phone subscribers in
Beijing.

Glitches in the software of a gateway mobile switching centre (GMSC)
provided by Nokia for the use of the Beijing Mobile Communications Co
Sunday deprived some fixed phone users in eastern Beijing, especially those
with phone numbers beginning in 64 and 65, of the ability to get through to
cellular phones with numbers beginning in 139, 136, 135, as well as some
other numbers owned by Beijing Mobile.

An emergency rescue team, composed of technicians from Nokia and Beijing
Mobile, spent the whole of Monday trying to salvage the situation.

Partly thanks to some software sent to Beijing from Nokia's Finnish
headquarters, the situation returned to normal at around 10:00 pm last night,
according to Pan Hui, of the Network Department with Beijing Mobile.

In a joint statement Nokia and Beijing Mobile said an on-the-spot check had
found that the problem had been caused by a failure in the software system
deployed by Nokia.

The malfunction surfaced early Monday morning, when the amount of people
making phone calls began to increase as people got down to work after the
weekend, according to Pan.

Beijing Mobile, in an effort to "satisfy market demands and further enhance
mobile telecommunication capacity," underwent a major equipment upgrade
between last Tuesday and Friday, but tests on fixed-mobile phone connection
and other technological aspects conducted over the weekend did not show up
any problems, according to the joint statement.

Those affected included China Daily and China Postal News, whose telephone
numbers begin with 64, and the foreign embassy district in Beijing's Chaoyang
District, according to Pan.

Dong Huiyi, president of Beijing Mobile, told China Daily last night that
connections between fixed phones and mobile phones were not completely
paralyzed as had been claimed by some users. However, he admitted that the
connection rate was deplorably low.

Usually, a GMSC processes 4,000 to 4,500 incoming fixed phone calls at any
one time. But Monday's "traffic jam" saw the number of phone calls waiting to
be connected to mobile phones rise to 25,000, by far exceeding the
processing capacity of the Nokia product, Pan said.

Monday's incident has made Beijing Mobile pull up its socks. Dong said the
company will continue to test the equipment to prevent something similar
happening again.
