Description
Technical field
The present invention relates to a kind of frequency allocation method of mobile communication system.
Background technology
At present, the frequency of mobile communication system carrier wave all is pre-specified, can not adjust in system's running.
Modern mobile communication development mainly passed by for two generations, and the third generation is in the nervous development stage now so far, and part producer has released the experiment product.3-G (Generation Three mobile communication system) is a kind ofly can provide polytype, high quality multimedia business, can realize global seamless covering, have the global roaming ability, compatible mutually with fixed network, and with the small portable terminal at any time, any place carries out the communication system of any kind of.
The target of 3-G (Generation Three mobile communication system) may be summarized to be:
(1) can realize global roaming: the user can roam in whole system even global range, and can obtain to have the service of quality assurance under different rates, different motion state.
(2) can provide multiple business: business, particularly multimedia service such as data, the non-words of motion video that speech, variable bit rate are provided.
The service that mobile communication mainly provides now remains voice service and low-rate data service.Because networks development, data and multimedia communication have had swift and violent growth momentum, so the target of 3G (Third Generation) Moblie is exactly wideband multimedia communication.
(3) can adapt to multiple environment: comprehensively current public switched telephone network (PSTN), integrated services digital network, cordless system, land mobile communication system, satellite communication system provide seamless covering.
(4) enough power system capacity, powerful multiple subscriber management capabilities, high security energy and high quality services.
3-G (Generation Three mobile communication system) is proposed in 1985 by International Telecommunication Union the earliest, be called Future Public Land Mobile Telecommunication System (FPLMTS at that time, Future Public Land MobileTelecommunication System), renamed IMT-2000 (InternationalMobileTelecommunication-2000 in 1996 as, International Mobile Telecommunication 2000), the meaning promptly this system works in the 2000MHz frequency range, the highest service rate can reach 2000kbit/s, is expected at about 2000 and obtains commercialization.Because code division multiple access (CDMA) power system capacity is big, be equivalent to 10～20 times of analogue system, and compatible good with analogue system, so CDMA technology become the core technology of 3G (Third Generation) Moblie, mainly system has WCDMA, CDMA2000 and UWC-136.
Below be example with the WCDMA system, introduce the distribution method of prior art frequency.
The WCDMA system mainly comprises: core net, Access Network and subscriber equipment.Core net is mainly carried out Business Processing, Access Network is mainly used in the subscriber equipment connecting system.WCDMA uses frequency spectrum to be: up: 1920～1980MHz, and descending: 2110～2170MHz.And the area, America: up: 1850～1910MHz, descending: 1930～1990MHz.Certainly, do not repel and use other frequency ranges, but uplink and downlink also are symmetrical.The WCDMA system is in planning period, and is that frequency allocation up, descending use is good according to above-mentioned regulation, in system's running, frequency do not carried out any adjustment.
As seen, in the existing WCDMA system, the frequency partition of up-downgoing is symmetrical, i.e. corresponding band downlink of uplink band, and the size of the frequency band of up-downgoing simultaneously equates that band downlink will carry all downlink business.Do not support the situation of asymmetric frequency band in the just present WCDMA system.
Yet frequency spectrum is a very important resource, also is unusual finite sum preciousness.If it is improper to utilize, can cause the great wasting of resources.
From the technical scheme of above-mentioned WCDMA Frequency Distribution, the division of up-downgoing frequency range be fix and also be complete symmetry, but different business is incomplete same to the demand of uplink and downlink frequency range.Particularly for 3G (Third Generation) Moblie (3G) business, because the business of 3G is abundant gradually, for example occurred: various types of characteristic services such as some multimedia services, video transmission service, visual telephone, data service will be in the time from now on dominate, promptly descending traffic carrying capacity will be much larger than up traffic carrying capacity.Therefore will cause the asymmetric of uplink and downlink traffic carrying capacity from traffic performance.
If the business that network provides increases, and but existing frequency spectrum is not enough, in order to support all business, can only be to increase frequency spectrum so, but, must be the frequency spectrum that increases up-downgoing simultaneously according to existing mechanism, and this moment, up traffic carrying capacity might be little, because up just some little data blocks or part signaling transmission basically, therefore newly assigned uplink band utilance will be extremely low, therefore this significant wastage of distributing frequency range certainly will cause the uplink band resource symmetrically.
