Description
Technical field
The present invention relates to the digital cluster communication field, relate in particular to the method that realizes the distant resurrection function of getting killed in a kind of digital cluster system.
Background technology
Mobile communication technology has developed into the third generation, and wherein trunking communication also becomes a kind of indispensable communication traffic day by day.Trunking communication is meant a kind of dispatching communication mode of special use, comprises special-purpose commander and dispatching communication, and in use cluster user can add calling simultaneously, and conversation is with simplex mode work.In broad terms, comprise that the various wireless communication systems with dispatching communication function of wireless intercom system all can include the category of trunked communication system in.
Historically, the development of trunking communication will be far away early than public mobile communication.Because technical sophistication, with high costs; Originally trunking communication must need such as army, railway, navigation etc. just to be used for the special sector and the unit of command scheduling; Afterwards along with the reduction and the expanding economy of development of technology, cost; The public mobile communication of social individual consumer's radio communication needs just occurred being fit to, even so, current cluster communication still belongs to personal communication system basically.
Trunking communication experienced simple intercom system (intercommunication form one to one) to single base station mini system (joining common-frequency simplex network construction form, alien frequencies list (two) worker network construction form, single channel get ready to go into action in hundreds form, band selective call form, multichannel dial automatically form); Arrive the development course of big capacity multizone system (the multichannel user shares form) again; After experienced again from the simulation cluster to the leap of Digital Clustering, this leap makes trunking communication all can adopt digital processing mode more reliably at the aspects such as multi-access mode, speech coding, modulation-demodulation technique, simultaneous techniques, error-detection error-correction and diversity technique of signalling coding, employing.
Two kinds of digital cluster systems of extensive use at present are based on iDEN that TDMA is a tdma (integrated Digital Enhanced Network) and TETRA (Terrestrial TrunkedRadio); In order to promote the sizable application of digital cluster system; Further boost the efficiency of frequency resources utilization simultaneously, trunked communication system a new application trend occurred on using, and a plurality of digital cluster systems is combined unify to use and manage exactly; Thereby be able to share channel and channel; Share overlay area, communication service, carry on a shoulder pole the purpose of expense altogether, cluster application realizes the common network operation from developing into towards indivedual professional users towards a plurality of group users the most at last.
Trunking communication has been promoted to go up the research that realizes Clustering at existing public network (GSM, CDMA) by the development of private network to common network.
Distant being explained as follows of getting killed and bring back to life in the CDMA2000 mobile communcations system: distant getting killed is meant system from security consideration, and travelling carriage is forbidden its part or all of function by force; Resurrection is meant that system activates recovery again to the travelling carriage that is in the distant state of getting killed; This function through aerial signaling travelling carriage is carried out positive lock or release realizes.
Patents more both domestic and external have been mentioned through high-level managing mobile phone to the note of being sent specific format by managing mobile phone, to reach the implementation method of remote activation/deexcitation travelling carriage partial function.Distant getting killed brought back to life the basic implementation method of function in group system, the existing argumentation in existing patent CN200510090588 " control method of remote deactivation/resurrection in the code division multiple access digital cluster system "; The distant implementation method of bringing back to life function of getting killed, the network element that relates to and basic signaling process have been introduced to this patent outlined.
