As shown in Figure 1, the 3G (Third Generation) Moblie base station NB of standard is arranged not only in the network of 3G (Third Generation) Moblie, also distributed simultaneously and utilized broadband cable network to be linked into the indoor household base station HNB of core net.When new indoor household base station HNB-new prepares to install, reasonably select working frequency points avoid to outdoor base station NB and in the installation room performance impact of Home node base station HNB need the emphasis consideration.
The method of the autonomous setting HNB operating frequency that the present invention proposes, key point is: to the indoor household base station HNB-new of new access, on the position of the good several pre-mounting points of planning all frequencies in the HNB-new equipment institute support performance frequency range are searched for, obtaining on every side, the signal spectrum of 3G (Third Generation) Moblie base station NB and indoor household base station HNB distributes and broadcast; Analyte signal intensity, frequency band take and the spectrum distribution situation.By the information of equipment, seek best HNB-new installation site: (1) in each pre-mounting points, determines that the NB that receives and the signal of HNB exceed the minimum position of interference threshold level;
(2) when having base station NB signal to exist, guarantee that the NB received signal quality is good;
(3) indoor household base station can cover the zone that will provide professional.
Best in quality or the good base station NB of selective reception extracts the synchronisation source of synchronizing signal as HNB-new under the situation that has base station NB.The analysis spectrum characteristic is selected all available frequency bands.According to the maximum carrier number information that HNB-new supports, determine the occupied bandwidth of HNB-new, in available band region, the frequency band that selection and HNB-new occupied bandwidth are complementary, the working frequency points of definite main carrier and auxilliary carrier wave in the frequency band of selecting.Adopt this autonomous frequency configuration mode, the performance requirement in the time of can guaranteeing HNB-new and already present HNB or NB coexistence.
In the described method, indoor household base station can obtain identification code, the dominant frequency point of peripheral base station NB and assist information such as frequency; Obtain identification code, the dominant frequency point of ambient indoor Home node base station HNB and assist the information such as maximum carrier number of frequency, the actual support of equipment.
Realize that above method comprises following six step,
(1) in 2～3 position that are fit to install HNB-new of indoor selection
As the position A among Fig. 2, position B and position C.HNB-new equipment is placed on position A, position B and position C place respectively.
(2) after HNB-new powered on and finishes initialization, HNB-new was set to receive the reference level condition.Receiving reference level can be to receive reference sensitivity level or self-defined received signal level.HNB-new searches for NB and HNB on every side in all 3G (Third Generation) Moblie working frequency range of its support, and obtains the broadcast of each NB and HNB correspondence, comprising identification code, dominant frequency point with assist frequency point information.According to identification code, frequency point information, can obtain NB and the HNB distribution on frequency domain.Among Fig. 3, Fig. 4 and Fig. 5,101～105th, the HNB that searches at the HNB-new periphery; 201～204th, the NB that searches at the HNB-new periphery; The interference threshold control level is 401.
(3) select best position.
The signal of the peripheral HNB that receives at position A, position B and position C place and NB is analyzed and compared.Statistics exceeds the signal number and the level size of interference threshold on each pre-installation site.

Bandwidth in 300～307 frequency bands has nothing in common with each other, when selecting the working frequency points of HNB-new, at first select the frequency that satisfies in 300～307 in the fragmentary distribution frequency band that the HNB-new bandwidth of operation requires for use, such as the interior frequency points corresponding of 301,303,300,306 frequency bands among Fig. 5, the frequency in other frequency bands 304,307,302,305 comparatively complete, broad uses for the HNB of follow-up access.The advantage of this system of selection is that the HNB that can improve follow-up access greatly selects the efficient of working frequency points.
When HNB-new is operated in the frequency of above selection, satisfy performance requirement in the time of can guaranteeing to coexist with existing system.
(5) if in whole frequency ranges that HNB-new supports, do not have idle frequency band, then the HNB-new bandwidth of selecting the flat NB of light current or HNB and selecteed NB or HNB is more than or equal to the working frequency points of the frequency in the required bandwidth of HNB-new as HNB-new.If HNB-new is a single carrier to be used and selecteed HNB or NB equipment also are single carriers, then the identification code of HNB-new should select to be different from the identification code of HNB or NB; If selecteed HNB or NB's is multicarrier equipment, then the working frequency points of HNB-new is chosen on the auxilliary frequency of HNB or NB.Use if HNB-new is a multicarrier, then the dominant frequency point of HNB-new need be chosen on the auxilliary frequency of HNB or NB.
(6) all have installed the also HNB of operate as normal, according to the order from access controller APC, start autonomous frequency configuration at any time ambient signals is scanned.If be used for occurring in the synchronous signal receiving quality variation, working band disturbing, then need reselect synchronisation source, upgrade the frequency of obtaining synchronizing signal, reselect frequency band and working frequency points.Adopt the method to solve when NB configuration in base station changes, increases the NB website when the 3-G (Generation Three mobile communication system) dilatation, downlink synchronous signal changes to the influence of HNB.
