Wherein, as shown in Figure 2, Configuration Control Unit 20 comprises: the first control module 202 is used for receiving the frequency configuration request of HeNB42, and sends frequency configuration information to HeNB42; Parameter generation module 204 is used for generating wireless environment detection parameter and bandwidth estimation parameter and being sent to HeNB42 according to the frequency configuration request; The second control module 206 is used for sending wireless environment detection and bandwidth estimation order to HeNB42, and receives wireless environment detection result and the bandwidth estimation result of HeNB42; Result treatment module 208 is used for the frequency configuration information according to wireless environment detection result and bandwidth estimation result generation HeNB42; Configuration database 210, the wireless environment detection result and the bandwidth estimation result that are used for storing each HeNB, work at present frequency and the bandwidth of each HeNB, the neighbouring relations of each HeNB, the relevant parameter of wireless environment detection and bandwidth estimation.
Wherein, the frequency configuration request comprises the request of initialization frequency configuration and reconfiguration request.Comprise wireless environment detection parameter and bandwidth estimation parameter request in the request of initialization frequency configuration, to parameter generation module 204 request wireless environment detection parameter and bandwidth estimation parameters.Then can not comprise wireless environment detection parameter and bandwidth estimation parameter request in the reconfiguration request.
When having interference signal to be wider than the idle frequence of bandwidth estimation result less than default threshold value and band in the optional frequency range of HeNB42, this frequency can be distributed to HeNB42, result treatment module 208 generates corresponding frequency configuration information.When not having interference signal to be wider than the idle frequence of described bandwidth estimation result less than default threshold value and band in the optional frequency range of HeNB42, Configuration Control Unit 20 is adjusted the parameters such as operating frequency, bandwidth and transmitting power of the adjacent HeNB of HeNB42, and result treatment module 208 also further generates the frequency configuration information of the adjacent HeNB of HeNB42.
Among the first embodiment, Configuration Control Unit 20 is positioned at mobile network's side, can or be arranged in HMS or operation maintenance center for independent network element.
As shown in Figure 3, HeNB42 comprises: the 3rd control module 420, be used for the generated frequency configuring request, and the frequency configuration request is sent to described Configuration Control Unit, and receives described frequency configuration information, frequency configuration information is sent to the frequency configuration module; The 4th control module 428, be used for receiving wireless environment detection parameter and bandwidth estimation parameter and wireless environment detection and bandwidth estimation order, wireless environment detection parameter and bandwidth estimation parameter are sent to respectively wireless environment detection module and Bandwidth estimation module, and wireless environment detection result and bandwidth estimation result are sent to described Configuration Control Unit; Wireless environment detection module 424 is used for carrying out wireless environment detection according to the wireless environment detection parameter of receiving, and generates wireless environment detection result; Bandwidth estimation module 426 is used for carrying out bandwidth estimation according to receiving the bandwidth estimation parameter, and generates bandwidth estimation result; Frequency configuration module 422 is used for the frequency according to the described frequency configuration information adjustment HeNB42 that receives.Among the first embodiment, HeNB44 ... HeNB4n is identical with the structure of HeNB42, does not repeat them here.
The radio detection parameter can comprise: sense cycle, detection zero-time, detection frequency range and Interference Detection parameter.Below above-mentioned parameter is specifically described:
(1) sense cycle and detection zero-time: be used for cycle and zero-time that configuration HeNB detects its wireless environment and reported result.Each HeNB needs to detect wireless environment in the different moment.During detection, carry out the HeNB that detects and to suspend emission, and other HeNB should work.Thereby to need Configuration Control Unit be each HeNB reasonable distribution sense cycle and zero-time.Configuration Control Unit needs according to this place's network user behavior in the past rational sense cycle to be set.Because HeNB should adapt to wireless environment variation, detects too continually wireless environment, conversion operating frequency for avoiding HeNB semi-staticly, sense cycle should be established longlyer.But be the ageing of Mark Detection result, can a term of validity be set for testing result, the term of validity is less than or equal to sense cycle.When testing result before the deadline, can think that the wireless environment of HeNB does not change.
(2) detect frequency range: be used for the frequency range that configuration HeNB detects wireless environment.Because HeNB is arranged by the user, and each operator is allocated to the frequency range difference that HeNB uses, notify the HeNB detection to need the frequency range that detects by configuration server, can reduce the duration that the detection wireless environment takies.Be further to shorten to detect duration, configuration server can also divide into groups HeNB, and HeNB on the same group shares certain frequency range, on the same group the different frequency range of HeNB use not, and Configuration Control Unit only need be notified its concrete detection frequency range of HeNB.At this moment detect frequency range and will be allocated to the frequency range that HeNB uses less than operator.
