Based on the above, the specific steps of the main controller judging whether the experimental mobile phone rings are as follows:
the interception equipment also detects ringing back information received by a public network base station in the calling phase of the calling equipment, and uploads all the ringing back information to be intercepted to the main controller, wherein the ringing back information contains TMSI/IMSI;
and the main controller searches all ringing back information according to the known TMSI/IMSI, judges whether the ringing back information containing the known TMSI/IMSI exists, judges the ringing of the experimental mobile phone if the ringing back information exists, and judges the ringing of the experimental mobile phone if the ringing back information does not exist.
Based on the above, the calling device sends an interception starting instruction to the interception device through the main controller when starting to call, and sends an interception stopping instruction to the interception device through the main controller when stopping to call.

Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly, an experimental mobile phone with a known number and TMSI/IMSI is used as a target mobile phone for carrying out calling duration training; calling by using the calling equipment, monitoring the paging message of the experimental mobile phone by the interception equipment, and continuously adjusting the calling time of the calling equipment, so that the interception equipment can receive the paging message of the experimental mobile phone and cannot ring the experimental mobile phone, and the minimum value of the calling time is obtained by repeated training.
Drawings

Fig. 2 is a schematic flow chart of a call duration training method according to the present invention.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
As shown in fig. 1, which is a GSM called flow chart, WDMA and CDMA called flow are similar. As can be seen from fig. 1, there is much signaling to interact from the beginning of the network Paging the mobile station (Paging Request) to the beginning of the mobile station ringing (Alerting), which is about several hundred milliseconds in duration. Therefore, if the calling is terminated immediately from the calling end after the network sends the paging to the mobile station, the effects of paging the target mobile phone and controlling the ringing of the target mobile phone can be achieved.
However, in practical application, the relevant unit only knows the mobile phone number of the target person, but not the TMSI or IMSI of the mobile phone, and when the network pages, the paging address in the paging message is the TMSI or IMSI. Therefore, it is not feasible to suspend the call of the calling party by recognizing the paging message in the network paging. One feasible method is to control the calling duration at the calling end, so as to achieve the effects of not only paging the target mobile phone but also controlling the ringing of the target mobile phone.
However, for different operators, different regional equipment providers, and different network busy and idle periods, the duration of the network processing call signaling may be different, and the network signaling processing time is in millisecond order. It is difficult to control the call duration accurately based on the experience or feeling of the operator.
Therefore, the invention provides a call duration training method according to a mobile phone called flow, as shown in fig. 2, the method includes an experimental mobile phone with a known number and a known TMSI/IMSI, a calling device, an intercepting device and a main controller, wherein the intercepting device is arranged in an area where the experimental mobile phone is located, and specifically includes the following steps:
inputting a known number, a known TMSI/IMSI and an initial call duration at the main controller;
the calling equipment starts to call the experimental mobile phone through the public network base station according to the initial calling duration and the known number;
the monitoring equipment monitors downlink paging signals sent by a base station in the area where the experimental mobile phone is located in the calling equipment calling stage, and uploads all monitored downlink paging information to the main controller, wherein the downlink paging signals contain TMSI/IMSI;
the main controller searches in all downlink paging signals according to the known TMSI/IMSI, judges whether the downlink paging signals containing the known TMSI/IMSI exist, if not, prolongs the initial calling time and controls the calling equipment to start calling again;
otherwise, the main controller judges whether the experimental mobile phone rings, shortens the initial calling time length when the experimental mobile phone rings, and controls the calling equipment to start calling again; or accumulating the training success times when the ringing is not performed, comparing whether the training success times are larger than the preset success times, if so, finishing the training, wherein the initial calling time is the ideal calling time, otherwise, controlling the calling equipment to start calling again.
The monitoring device comprises eight wireless communication target data acquisition terminals and a WIFI terminal, wherein the eight wireless communication target data acquisition terminals comprise mobile GSM, Unicom GSM, telecom CDMA, mobile TD-SCDMA, Unicom WCDMA, mobile TDD-LTE, Unicom FDD-LTE and telecom FDD-LTE, so that the monitoring device can monitor downlink information of all base stations of different operators, and the application range of the system is enlarged.
Specifically, the specific steps of the main controller judging whether the experimental mobile phone rings are as follows:
the interception equipment also detects ringing back information received by a public network base station in the calling phase of the calling equipment, and uploads all the ringing back information to be intercepted to the main controller, wherein the ringing back information contains TMSI/IMSI;
and the main controller searches all ringing back information according to the known TMSI/IMSI, judges whether the ringing back information containing the known TMSI/IMSI exists, judges the ringing of the experimental mobile phone if the ringing back information exists, and judges the ringing of the experimental mobile phone if the ringing back information does not exist.
Preferably, in order to reduce the number of useless downlink paging messages and facilitate statistics and analysis, the calling device sends an interception starting instruction to the interception device through the main controller when starting a call, and sends an interception stopping instruction to the interception device through the main controller when stopping the call; or the main controller is also provided with a call starting time and a call stopping time, the main controller sends a call starting instruction to the calling equipment and sends an interception starting instruction to the interception equipment at the call starting time, and the main controller sends a call stopping instruction to the calling equipment and sends an interception stopping instruction to the interception equipment at the call stopping time.
By the two calling and intercepting control means, the intercepting equipment only intercepts in the calling time period of the calling equipment, and the number of useless downlink paging information is greatly reduced.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
