Description
Technical field
The present invention relates to wireless telecommunication system, particularly a kind of wireless communication method of many communication lines.
Background technology
In the prior art, GPRS is that the English of GPRS (General Packet RadioService) is called for short, and is a kind of new bearer service that development is come out on existing gsm system, and purpose is the data service that block form is provided for GSM user.The GPRS theoretical bandwidth can reach 171.2Kbit/s, and the practical application bandwidth is greatly about 40-100Kbit/s.GPRS uses CS2 pattern, CLASS 12 modes usually, provides up-downgoing to be respectively the 53.6Kbps transmission bandwidth.
EDGE (Enhanced Data Rate for GSM Evolution), i.e. enhanced data rates for gsm evolution technology.It mainly is to have adopted a kind of new modulator approach in gsm system, promptly state-of-the-art multi-slot operation and 8PSK modulation technique.Because 8PSK can expand to 8 from 2 with the signal space that has the GMSK modulation technique of GSM network using now, thereby the information that each symbol is comprised is original 4 times.Thereby significantly improve transmission bandwidth.EDGE network can provide the upstream bandwidth of 80～100Kbps, the downlink bandwidth of 200Kbps usually.
CDMA 1X original meaning is meant the phase I (speed is higher than IS-95, is lower than 2Mbit/s) of cdma 2000, can support the transfer of data of 308kibit/s, network partly to introduce packet switching, can support mobile IP service.Be a kind of new bearer service that development is come out in existing CDMA IS-95 system, purpose is the data service that block form is provided for CDMA user.CDMA 1X theoretical bandwidth can reach 300Kb/s, and present practical application bandwidth is about about 100Kb/s (bi-directional symmetrical transmission) greatly.
At present on 2.5G or 2.75G data network, as GRPS, EDGE, CDMA 1X etc., the transmission bandwidth that can provide is usually between 20Kbps～150Kbps, though its limited data bandwidth can satisfy the needs of most of transfer of data, but in the application of high bandwidth requirements such as image transmission, be difficult to satisfy application demand.Attempt to improve efficiency of transmission when the forward part technology, increase effective transmitted data amount, but can not improve the actual bandwidth of transmission by technology such as data compressions.Especially in applied business such as image transmission, data are to be compressed processing, do not have compressed possibility once more.Thereby much claim and method of compressing image data to come down to reduce data volume further sacrificing image pixel.
In the prior art, the technology of attempting to improve bandwidth is also arranged, for example the Chinese invention patent application 200610009219.3, the technology of disclosed " a plurality of physical channels of combination in wireless communication system " by name, and Fig. 1 schematically illustrates the selected part of the wireless communication system 20 of its application documents.Its technical scheme comprises: mobile radio station 22 communicates with wireless network 24.The known portions that has comprised wireless network in illustrated example, for example antenna for base station 26, base station transceiver 28, router three 0, radio network controller 32 and packet data serving node (PDSN) 34.In this example, wireless network 24 can connect 36 and communicate with one or more remote equipments via the internet, and wherein said remote equipment can be a software application server 38.In the illustrated embodiment, mobile radio station 22 can be finished several data and communicates by letter by communicating with application server 38. and described illustrated example then is fit to handle these class needs and uses very high data throughout to realize the situation of enough application performances very much.Illustrated mobile radio station 22 comprises a plurality of wireless access terminals 40,42.In an example, mobile radio station 22 has comprised notebook, and wireless access terminal 40 and 42 have comprised the wireless network card of selling slightly on the market.Wherein a kind of illustrative wireless access terminal is usually said Air Prime 5220 PCMCIAEVDO network interface cards.Can use multiple known technology that the wireless access terminal is coupled to mobile radio station 22 here.In an example, mobile radio station 22 has had more than one wireless access terminal.
In another example, terminal is connected to mobile radio station selectively in expectation.Each wireless access terminal 40,42 all communicates with base station 26 via physical traffic channels.In illustrated example, wireless access terminal 40 communicates via first physical traffic channels 44, meanwhile, wireless access terminal 42 communicates via second physical traffic channels 46. and for instance, each bar physical traffic channels transmits at least a in voice or the packet.And each bar physical traffic channels has certain handling capacity or bandwidth.
In illustrated example, by two physical traffic channels 44,46 are combined into single logic channel, and, can provide the handling capacity of increase by local synchronization ground at least using these channels and communicate by letter transmitting between mobile radio station 22 and the base station 26.
By to this technical scheme analysis as can be known: this scheme must rely on the support of wireless network side apparatus when realizing, the networking inconvenience implements difficulty, on real network, is difficult to realize through test.
