Description
Technical field
The present invention relates to wireless network power control techniques field, more particularly to a kind of power for realizing 3G and WLAN layerings
Control method and system.
Background technology
Home eNodeB（Home NodeB）Also known as Femto, it is a kind of low transmitting power, small range covers, with fixed broadband
Access network is backhaul, is mainly directed towards the household base station device of domestic customers application.Transmitting power of equipment is small（Peak power
20mW）, small volume, work in mandate frequency range, covering radius is generally 5-20 rice, and its main function is to provide the user with
Higher service rate simultaneously reduces expense required during using high rate services, meanwhile, it is wireless to make up existing distributed cellular
The deficiency of communication system covering.
With the popularization of intelligent terminal and flourishing for mobile Internet, user is continuing to the demand of wireless bandwidth
Increase.The user data traffic increased rapidly causes 3G carrier networks can't bear the heavy load, and traditional grand net builds the side of dilatation
Method does not catch up with the growth of data traffic much.In order to solve current problems faced, in recent years, 3G network is disposed by Femto
Mode more and more received by operator.Because quite a high proportion of 3G data services are completed indoors, because
This can carry out indoor depth covering by Femto Home eNodeB, solve 3G macro stations to a certain extent and room subsystem is held
Amount can not meet the problem of data volume increases.
On the other hand, WLAN technologies are as a kind of flexible wide-band wireless IP access way in recent years, by its access speed
Rate is high, and framework is easy to use, the characteristics such as system cost is cheap, has obtained the clearly accreditation of industry.It is explosive for data service
Growth, and higher and higher bandwidth demand, traditional 3G network is difficult to meet, and WLAN is with the excellent of its distinctive high bandwidth
Gesture, support user with higher speed accessing data service.Secondly, using WLAN as the access of data service, can shunt
The data service of traditional 3G network, mitigate network burden.Can be as the strong supplement of 3G network.
Found by 3G and WLAN contrasts, WLAN has provided the user the number of higher rate by way of focus covering
According to business, but ambulant demand can not be supported well；, can be very and 3G network realizes continuous covering by cellular cell
Good support mobility, it is more much lower than wlan network in terms of the speed of data service.Therefore, WLAN and 3G network are entered
Row fusion, realize that WLAN has complementary advantages with 3G network, turn into the trend of future wireless network development.
Because WLAN working frequency range is in 2.4GHz and 5GHz, and TD-SCDMA working frequency range be respectively A frequency ranges 1880 ~
2010 ~ 2025MHz of 1920MHz, B frequency range.The frequency of wireless signal is more highly attenuating faster, that is to say, that the feelings of identical transmission power
The area coverage of 3G signals is greater than WLAN signal under condition.And the signal attenuation of open space is influenceed by many, away from
From, space environment, antenna height etc..Due to diffraction, scattering, reflection, the reason signal such as absorption will cause decay and distortion.Instead
Receiving terminal will be reached by different path by penetrating signal, and these signals are by with different path lengths, differential declines and not
Same delay.But effect of the attenuation factor of multipath and antenna height etc. for WIFI and 3G in same base station is all identical
's.
In the prior art, because Wifi focuses are few, after user leaves the WLAN signal covering being presently in, it is most likely that
Periphery does not have new Wifi focuses, then the data service that user is done will just be interrupted, and great inconvenience is brought to user.
The content of the invention
In order to solve above technical problem the invention provides it is a kind of realize 3G and WLAN layering Poewr control method and
System, propose to realize control 3G and the layered coverage of WLAN signal scope by configuring transmission power, avoid working as when user leaves
After preceding residing WLAN signal covering, due to the signal interruption problem that not new Wifi focuses are brought, ensure data service
Continuity.
