In addition, the abbreviation of general packet radio service technology (General Packet Radio Service), he is GSM
A kind of available mobile data services of mobile phone user.GPRS can say be GSM continuity.GPRS is continuously passed in channel with previous
Defeated mode is different, is to be transmitted with package (Packet) formula, therefore the expense that user is born is with its data transmission list
Position calculates, and not uses its entire channel, theoretically inexpensively.The transmission rate of GPRS can be promoted to 56 even 114Kbps.
GPRS is often described as " 2.5G ", that is to say, that this technology is located at the second generation (2G) and the third generation (3G) is mobile
Between mechanics of communication.He is by providing the data transmitting of middling speed using not used TDMA channel in GSM network.GPRS is broken through
GSM net can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Part transformation is carried out to realize packet switch, the investment of this transformation is comparatively and little, but obtained user data rate
Considerable.Moreover, connection and transmission all can because no longer needing intermediary's converter required for existing wireless application
It is more convenient to be easy.In this way, user can both connect to the internet, the interactive communications such as video conference are participated in, and in the same video signal net
The user of (VRN) on network, it might even be possible to dial up on the telephone without passing through, and continue and be connected to the network.
For the communication mode of GPRS packet switch in the communication mode of packet switch, data are divided into the packet of certain length
(grouping) has a packets headers before each packet (address mark therein indicates the grouping is sent to where).Data transmission it
Before do not need to allocate channel in advance, establish connection.But when each data packet reaches, according to the information in datagram header
(such as destination address) temporarily finds an available channel resource and sends the datagram.In this transmission mode, number
According to the side's of sending and receiving cochannel between there is no fixed occupancy relationship, channel resource can be regarded as being total to by all users
Enjoy use.Since data service all shows a kind of paroxysmal business characteristic in most cases, to channel width
Changes in demand is larger, therefore will preferably utilize channel resource using packet mode progress data transmission.Such as one into
The user of row WWW browsing, most of the time are in browse state, and really only account for very little ratio for the time of data transmission.
In this case according to the mode of fixed busy channel, it will cause the biggish wasting of resources.
