The method comprises the following steps that: a monitored party receives a remote monitoring request from a monitor party, wherein object control information is included in the remote monitoring request; the monitored party successfully receives the remote monitoring request, replies confirmation information to the monitor party, resolves the object control information and selects a launching mode; and the monitored party is in a monitored state, automatically starts launching and launches according to the selected launching mode. By adopting the embodiment of the invention, the function of remote monitoring of an interphone is enhanced, and the launching time or the launching intervals and frequency of the monitored party can be actively controlled by the monitor party to realize circulated monitoring. Moreover, the method and the system which are provided by the embodiment of the invention do not completely depend on the arrangement of customer program software (CPS), can be operated through a human-computer interface during application; by setting the object control information, the launching time of the monitored party can be flexibly controlled.
Description
Technical field
The present invention relates to communication system, particularly a kind of implementation method of remote monitoring, Apparatus and system.
Background technology
In the use procedure of intercom, the target side of calling out as the user as call initiator (this user possesses corresponding administration authority) is that monitored side does not respond, and wants to understand the other side's situation, and don't wants to allow the other side perceive; Or machine is lost or is stolen, need to pursue its whereabouts time; Or target intercom user causes danger, need real-time tracking situation, and other various occasions, can, by using intercom remote monitoring function, monitor target intercom situation around, to take appropriate measures.
This remote monitoring function, be exactly that initiator sends a remote monitoring instruction to target intercom, target intercom receives after remote monitoring instruction, automatic activation microphone and putting call through immediately after connection (PTT, Push ToTalk) button, initiate automatically the transmit leg of an individual call to instruction simultaneously, and continue the transmitting regular hour, but target intercom is without any transmitting indication, and targeted customer also knows nothing.In this case, all sound (voice or background sound etc.) that target intercom around produces, all launching by secret.
At present in intercom remote monitoring technology, implementation procedure is all like this: first by user program software (CPS, Customer Program Software) the monitored time of Offered target intercom (being launch time), afterwards, based on digital mobile radio (DMA, Digital Mobile Radio) agreement, monitoring side and monitored square tube are crossed control signal piece (CSBK, Control Signalling Block) carry out alternately, be specially: the long-distance user i.e. side of monitoring sends a remote monitoring instruction to target intercom, target intercom replys confirmation (ACK) information in the side of monitoring to the initiator of instruction after receiving remote monitoring instruction, then secret startup launched, the time of transmitting is the regular time arranging by CPS before, and only transmitting once, after finishing launch time, exit monitored state.
Existingly realize in remote monitoring technology by intercom, at least have following shortcoming:
1, after the monitored time of target intercom (being launch time) finishes, exit monitored state and finish whole process.It cannot be realized after certain time interval, automatically starts transmitting and certain number of times that circulates.Can not meet under some application scenarios, need monitored side to report automatically the function of the background environment situation of self to monitoring side.
2, the monitored time of target intercom (being launch time), be set to a certain set time by CPS, once after setting, cannot change in the process using, if need change, must reset by CPS.From another side, the time of monitoring is not to be determined by monitoring side, but is determined by monitored side oneself, lacks flexibility.But in actual use, monitoring side need to, according to actual conditions, determine the listening period to monitored side.
