Description
Technical field
The present invention relates to the digital aggregated communication system field, particularly a kind of in digital aggregated communication system implementation method and a kind of data cluster communications terminals of terminal GPS positioning function.
Background technology
Digital aggregated communication system is an important branch of mobile communcations system, is a kind of mobile communcations system that is applied to group's dispatch control communication.Be mainly used in professional field of mobile communication, like government department, army, police service, all trades and professions such as railway, water conservancy, civil aviaton and steel logistics.
Digital aggregated communication system network configuration (like Fig. 1) mainly comprises colony terminal 1, base station sub-system 2, and scheduler subsystem 3, wherein:
Colony terminal 1 possesses the terminal equipment of group service function, is the mutual capital equipment of cluster network and user;
Base station sub-system 2 (hereinafter referred base station) possesses the base station system of group service function, accomplishes the access function at terminal, is the capital equipment of connecting terminal and scheduler subsystem;
In this article, for easy base station sub-system 2 is merged with scheduler subsystem 3 is called the base station scheduling subsystem, be called for short system side.
The terminal in use, the system's more specific location information that need know the terminal is work such as to dispatch sometimes.In the case, need terminal to report self-position information to give system side, like current longitude and latitude, self speed, direction etc.Realize this function, several steps below needing to accomplish:
1, system sends to the terminal and requires to report order;
2, self-position information is collected at the terminal;
3, terminal to report self-position information.
In this process; Traditional processing mode is, step 1, the 3rd is accomplished by short message mode, and promptly system sends a note to the terminal; The content of note is a requirement terminal to report self-position information (step 1); After this information of terminal collection (step 2), send note to system side, short message content is self-position information (step 3).But under the Digital Clustering communication mode, be in the terminal under the business state (group call state), may receive and send note, promptly can't be by above-mentioned traditional communication modes and system side communication.
In addition, in cluster GPS position fixing process, system need send the GPS control information to the terminal sometimes, as the terminal is set whether need reports the GPS information of self, report cycle or report mode etc.This control information (is in Idle state or normal speech conversation state etc.) in the ordinary course of things and sends with short message mode like the terminal.But when the terminal was in trunked call state (being group calling), the terminal was the short message that can't receiving system issues.
In sum; In carrying out the PTT group-calling process, system side is no longer known the specifying information at terminal, so can't use short message mode to send control information to the terminal; Self-position information also can't be sent through short message mode in the terminal; Therefore, realize under the Digital Clustering communication mode the GPS locating information report the reception with system control information, just need a kind of brand-new communication mode.
Summary of the invention
Technical problem to be solved by this invention provides a kind of digital group system terminal and GPS locating information report method thereof, realizes reporting of terminal GPS locating information.
The present invention is directed to the PTT conventional group calling the time the GPS positioning function, be SDB (Short Data Burst, short data burst) signaling mode with the information translation of original short message mode.The terminal sends to system with the GPS locating information through the SDB signaling, and system also sends the control information of SDB signaling and gives the terminal, adopts the short message pattern to read during the receiving control information of terminal.
In order to solve the problems of the technologies described above; The invention provides terminal GPS locating information report method in a kind of digital cluster system; Comprise: when system requirements terminal to report GPS locating information, said terminal reports to system after self GPS locating information is configured to short data burst SDB message.
Further, said method comprises: A, system send SDB message to the terminal; B, the GPS locating information if judge that said message is the order that requires terminal to report GPS locating information, is then collected after verification is passed through to said SDB message in said terminal; C if said terminal judges self is in the trunked call talking state, then will collects said GPS locating information and be configured to SDB message, be that content is sent PTT GPS location response message to system with said SDB message.
Further; The said order that requires terminal to report GPS locating information is for requiring the terminal and repay immediately or requiring the terminal regularly to repay; When requiring the terminal regularly to repay; Also carry time parameter in the said order, said terminal reports the GPS locating information of self to system in the time of time parameter indication.
Further, the said order that requires terminal to report GPS locating information is that data are downloaded the DATA_DNLD order.
Further; In said step B, said terminal judges further whether the order of carrying in the said message is parameter modification PARAM_MDY order after verification is passed through to said SDB message; If; Then store the system parameters that PARAM_MDY order is carried, and according to the event memory at terminal, the response of replying successfully or failing to system.
Further, the said PARAM_MDY order system parameters of carrying is any one or a few in the following parameter: service centre's number, software version number, administrative center IP, administrative center's port, exhalation news in brief shortcode, telephone number.
In order to solve the problems of the technologies described above, the present invention also provides a kind of digital group system terminal, comprises GPS module and terminal control module, wherein:
Said GPS module is used for the order that receiving system requires terminal to report GPS locating information, and reports the GPS locating information at said terminal self to system;
Said terminal control module; After being used to receive that system requirements reports the order of GPS locating information; Collect the GPS locating information of self; When self being in the trunked call talking state, the said GPS locating information of collecting is configured to short data burst SDB message, report to system through PTT GPS location response message.
Further; When said terminal control module also is used for regularly repaying the GPS locating information at the system requirements terminal; Store the time parameter in the said order that requires terminal to report GPS locating information, and send the GPS locating information of self to system in the time of said time parameter indication.
Further; Said terminal control module is used for also judging whether the order that said message is carried is parameter modification PARAM_MDY order, if then store the system parameters that the PARAM_MDY order is carried; And according to the event memory at terminal, the response of replying successfully or failing to system.
Further, the said PARAM_MDY order system parameters of carrying is any one or a few in the following parameter: service centre's number, software version number, administrative center IP, administrative center's port, exhalation news in brief shortcode, telephone number.
Adopt the method for the invention and terminal, make the terminal when being in group calling, the control messages that still can receiving system issues also can report self-position information to give system side simultaneously.
