Other carrier frequency pathway closure district of its time gap correspondence when the 405-indoor base station obtains synchronizing signal;
The signal processing method of the overloading frequency multi-cell that present embodiment adopts comprises the steps:
Step S101, indoor base station starts;
Step S102, at first indoor base station works in terminal pattern, and the signal of macro base station and other indoor base station around receiving is measured the power and signal quality of ambient signals, and receives the broadcast on the broadcast channel, obtains adjacent sub-district with tabulation and alien frequencies tabulation frequently;
Step S103 is according to the working frequency points that the signal quality of macro base station around adjacent cell list that reads and the measurement determines to draw carrier frequency, structure traction sub-district on this traction carrier frequency; According to the situation of the macro base station that exists on every side and other indoor base station, be criterion with this indoor base station with mobile communication system interference minimum each other on every side, select the working frequency points of business carrier frequency, and construct service district with this;
Step S104, the best or good macro base station of selective reception signal quality or other indoor base station are the synchronisation source of this indoor base station, receive the down-bound pilot frequency signal of synchronisation source and extract synchronizing signal; If signal on every side can't reach the signal conditioning as synchronisation source, then oneself to be the living synchronizing signal of main product; If indoor base station is to be synchronisation source with outdoor macro base station or other indoor base station, then this indoor base station need receive downlink broadcast channel 301 and the down-bound pilot frequency signal 302 from synchronisation source in the time slot of downlink broadcast channel on traction carrier frequency or other carrier frequency and descending pilot frequency, extracts synchronizing signal; And remaining other carrier frequency passage is not launched any signal on the gap at this moment, this time gap 405 can be controlled to be closed condition for guaranteeing the synchronizing signal quality that receives;
Step S105, with periodically or the mode of Event triggered start synchronizing process;
Step S106 is converted to base station mode with indoor base station, sends the broadcast channel 101 and the down-bound pilot frequency signal 102 of traction sub-district on the traction carrier frequency, sends the broadcast channel 201 and the down-bound pilot frequency signal 202 of service district on business carrier frequency;
Step S107 on the sub-district of traction carrier frequency structure, monitors the mobile phone users that enters, and obtains the identification code of mobile phone users,
Step S108 judges whether it is authorized user, whether provides professional for it on business carrier frequency with decision;
Step S109, unauthorized user will be repatriated back macro base station;
Step S110 is moved to it on business carrier frequency authorized user, keeps the normal signaling link of itself and service district and the business of being asked is provided at any time moving to mobile phone users on the service district;
Step S111 causes that when surrounding environment changes condition that indoor base station relies on changes can't use the time, or indoor base station operation irregularity or when resetting, indoor base station need restart above-mentioned process.
Need further be pointed out that, if when not monitoring the suitable outdoor base station of received signal quality or other indoor base station signal when terminal pattern, this indoor base station will independently be set system information of subdistricts such as the working frequency points, cell ID of traction sub-district and service district.
In the described method of above-mentioned execution mode, the choosing method of indoor base station business carrier frequency is criterion with indoor base station with mobile communication system interference minimum each other on every side, in the working frequency range that indoor base station is supported, the frequency in the available band that selection need of work bandwidth actual with it is complementary in available frequency table is as working frequency points." a kind of method of autonomous configuration 3G (Third Generation) Moblie indoor base station operating frequency " application for a patent for invention of the visible the applicant of concrete grammar.
Above-mentioned embodiments of the present invention; be not to be restriction to claim protection range of the present invention; those skilled in the art can make various changes and modifications at the mobile communication system of other standards in the appended claim scope of the present invention, can fall into the scope of the present invention too.
