Method and device for controlling uploading of locating information of terminals in clustering system

Abstract

The invention discloses a method and device for controlling uploading of locating information of terminals in a clustering system. Configuration resource information is allocated to each terminal, configuration resource information signals are allocated to the terminals through a control channel, and each configuration resource information signal comprises starting time T when the corresponding terminal uploads the locating information. When T-t time is up, dynamic management information signals are issued to each terminal through an auxiliary control channel, wherein t represents the duration needed by uploading the locating information. When the starting time T is up, data frames which are uploaded by the terminals and carry the locating information meeting the corresponding requirement of the dynamic management information signals are received through the auxiliary control channel. The thermals can orderly upload the locating information, the occurrence of data collision due to the fact that the terminals disorderly upload the locating information to the clustering system is effectively avoided, meanwhile, the dynamic management on all terminals can be achieved, and the efficiency and accuracy that the terminals upload the locating information are improved.

Description

technical field [0001] The invention relates to the field of private network communication, in particular to a control method and device for uploading terminal positioning information in a cluster system. Background technique [0002] With the continuous development of private network communication technology, the trunking communication system has been widely used in all walks of life due to its multiple functions, good confidentiality and incomparable scheduling capabilities, and has also exerted good application benefits. Communication systems are becoming increasingly important. [0003] Cluster terminal positioning is a bright spot in the current private network cluster communication application, and it is also a practical demand put forward by many users in use. For example, in the application of a typical trunking system in the public security field, the dedicated digital trunking communication system is required to have a positioning function, and each terminal is re...

Problems solved by technology

[0005] Through the actual measurement, it is obvious that the effect of passive uploading to obtain terminal location information is not very good. For example, under the existing PDT (Police Digital Trunking, police digital trunking) standard After the system sends the command to upload its own positioning information, the number of terminals that can upload positioning information within a unit of time is very small, which cannot meet the requirements of a large number of terminals uploading positioning information in a short period of time in actual work scenarios and the implementation effect is poor.

The reason is that after the terminal receives the positioning information upload command issued by the system on the control channel, the terminal sends (uplinks) its own positioning information to the server on the system side on the control channel. At this time, the uploaded data collision is very serious. The reason The uplink of the control channel itself has other services (voice service, data service, signaling service, etc.) going on, which will occupy the uplink of the control channel, resulting in excessive pressure on the uplink, so the collision of positioning information is inevitable; When many terminals need to upload positioning information, especially when the upload cycle is short, the out-of-order uploading of positioning information by each terminal makes the data collision in the uplink transmission of the control channel more serious. Not only the function of uploading positioning information cannot If it is done well, it will affect the normal operation of other services such as voice and data in the system

[0006] However, the problem brought about by the method of actively uploading positioning information by terminals is that due to the lack of unified management of terminals, the disorderly and active uploading of positioning information by terminals also brings the problem of data uplink collision; In the case of uploading positioning information, the upload cycle will become very long, and the good effect of positioning information uploading will not be achieved

[0007] Based on the above analysis, simply using the active upload of terminal location information or the passive upload of terminal location information cannot bring good results
