||Introduction of GPRS technology
Answer: GPRS, General Packet Radio Service , is a new packet data
communications system sprung out of today¡¯s fixed telecommunications
networks. GPRS is the mainstream technology of the worldwide mobile
communications transition to 3rd generation, it's a very important
and indispensable approach and landmark in the migration from second
generation to the third generation (3G) mobile networks. We call
it the 2.5G mobile communications technology.
GPRS is particularly suitable for discontinuous , unexpected or
frequent , a small quantity of data transfer, and suitable for sporadic
mass data transfer. GPRS could be used within the PLMN or the packet
data transfer between GPRS network and the external packet data
network( IP, X.25). GPRS offers the seamless connection to the present
data network. With GPRS, the information is split into separate
packets before being transmitted .GPRS facilitates instant connections
and high immediacy whereby information can be sent or received immediately
as the need arises . Moreover, connection speed of GPRS facilities
could reach from slower than 100bps to maximum 171.2kbps, that is
sufficient for needs range from low-speed SMS transfer or high-speed
enhanced web browsing. All kinds of applications less than one time
slot could take advantage from GPRS, because different users could
share one time slot.£<
The basic working principle of GPRS is: With GPRS, the information
is split into separate but related packets before being transmitted
and reassembled at the receiving end, instead of using present fixed
data transition. Which facilitates sharing network resources between
users, and allow the service-providers optimize existing facilities
and create new income source.
||Value-add Service of GPRS
Except for transportation system, GPRS has enormous potential in
other trades. for example,
Kinds of exciting information will be delivered to mobile users, including
stock price, sports news, weather forecast , flight schedule, news
title , entertainment and traffic information, etc.
People prefer directly talk to each other than communicating by data
transfer, so internet chat room is very popular these days, people
who share the same interest and hobby could talk and discuss topics
with non-voice mobile service. Thanks to the cooperative function
of the GPRS and internet, GPRS will allow mobile users fully participate
in the existing internet chat rooms , no more chat room of user's
own is needed to be built. That is a very important feature for GPRS.
Circuit switched data services can't ensure the mobile users logging
on to the Internet all the time to surf the pages. Because of the
low speed data transmission, it will take a long time for the data
transfer from internet server to the browser. That's the reason why
the GPRS is much better for web browsing.
File-share and cooperative work
Mobile data brings convenience to FILE-share and cooperative work,
so that people in different places could work with the same files.
Non-voice mobile service can be used to assign new task to outworkers
and keep them in touch. At the same time, with non-voice mobile service,
the service engineers or the sales men could ensure the headquarters
knowing the rate of progress of the client needs.
Due to the work needs , in some companies, a lot of employees have
to leave the office, it is very important to expand the intranet E-mail
system on the PC in their office then to keep the connection between
the employees and their office.
The extension of GPRS could connect the mobile terminate to the PC
E-mail and expand the application range of enterprises.
Internet E-mail can become a gateway operation in which the information
cannot be saved, or a mailbox operation in which information can be
saved. In gateway operation , wireless mail platform will transfer
the information from SMTP to SMS and send to the SMS center.
static graphics such as photo, picture, postcard, card or speech draft
could be sent and received via mobile network.
With GPRS, graphics could be transfered from a digital camera which
is connected to GPRS wireless facilities , to an internet website
or other receiving facilities, and can be real-time printed.
When employees are not at their desk working, they need to connect
with the LAN of their office. All application in remote LAN are allowed
File transfer, including all kinds of transfer ,eg., downloading relatively
large quantity of data from mobile network.
||How is the GPRS network transition and what
is the capacity?
Answer: China Mobile GPRS network covers 31 provinces and more
than 240 cities in our country now , with a capacity of 2.1 million.
China Mobile will construct a GPRS covers the biggest area , with
the largest capacity and the best quality in China, due to its leading
technology and unparalleled investment. Along with the gradually
development and the extensive practice of GPRS technology, GPRS
network will definitely become the most mainstream transmission
way of mobile data transfer step by step. Wherever in flourishing
cities , or in remote suburbs, GPRS could provide high-speed data
service for the new generation, business man and enterprise-users
in all trades .
The world's top 200 largest mobile enterprises have chosen GPRS
network, that deliver GPRS service to everywhere in this world,
meanwhile , China mobile users could communicate with Hongkong,
Taiwan and Singapore freely , which means the telecommunication
is being brought into effect.
At mid-2002, China Mobile will launch a new GPRS network service
with optimization and enhancement. At that time, the data transmission
speed of GPRS will be about ten times as fast as speed of GSM networks
nowadays. Broadband communication, visual data, multimedia data
will all become more realistic and more convenient for mobile users.
||What is the marketing orientation
of China mobile developing GPRS?
Answer: The main objective of China mobile constructing and developing
GPRS network is to bring its clients the lastest information data
service and to deliver a real fresh and fashionable customized data
China Mobile GPRS Service will provide the most exciting service
for the upper business man and the young fashion-oriented , new-tech
followers. Those services include mobile business consultation,
mobile work and mobile entertainment. With the further promotion
and more actualization of the Monternet Project, applications
based on GPRS will be more prosperous and can provide types of mobile
data information services on life, work and study for mobile clients.
GPRS users can access any webpage or other Internet applications
anytime, anywhere - thanks to GPRS's immediate critical mass of
