Description
Technical Field
The present invention relates to information reporting technologies in digital trunking communication systems, and in particular, to a method and an apparatus for reporting positioning information by a terminal in a digital trunking communication system.
Background
The digital trunking communication system is an important branch of mobile communication system, and is a mobile communication system applied to group dispatching and commanding communication. The method is mainly applied to various industries in the field of professional mobile communication, such as government departments, military troops, police affairs, railways, water conservancy, civil aviation, logistics and the like.
The network structure of the digital trunking communication system mainly comprises a terminal, a Base Transceiver Station (BTS) subsystem and a scheduling subsystem. The terminal is a terminal device with a trunking service function, and is also a main device for interaction between the trunking network and the user. The BTS is a base station system having a trunking service function, is used to complete access of a terminal, and is a main device for connecting the terminal and a scheduling subsystem. The dispatching subsystem is a control center of the trunking service and is used for finishing the control and management of the terminal trunking service in the service area; the dispatching subsystem comprises a Mobile-services Switching Center (MSC for short) and a trunking dispatching Server (PDS for short), wherein the MSC is used for controlling common voice, and the PDS is used for controlling Push To Talk (PTT for short) calling. The combination of BTS and scheduling subsystem is referred to herein for simplicity as a base station scheduling subsystem, simply system.
Currently, with the increasing development of communication technology, more and more functions are added to communication devices. In order to enhance the competitiveness of digital trunking communication systems in the communication market, Global Positioning System (GPS) functions have been added to digital trunking communication systems. For a terminal in a digital trunking communication system, a GPS module is added in the terminal, and the GPS module is mainly used for receiving data from a GPS satellite and obtaining current positioning information, such as current longitude and latitude, self speed, direction, and the like.
In addition, the terminal is also provided with a load module and a main control module, wherein the load module is used for processing related to the GPS, such as setting a sending period, arranging GPS data and the like; the load module is a connecting module of the GPS module and the main control module and has certain operation control capability. The main control module is a main control module of the terminal and is used for information interaction between the terminal and the system side and overall operation control of the terminal.
In the GPS positioning process, the system sometimes needs the terminal to report its current positioning information, which is used to make the system more conveniently position the location of the terminal, thereby realizing the monitoring of the system on the terminal. When the system requires the terminal to report the current positioning information, the system sends system positioning control information to the terminal, and then the terminal reports the self positioning information according to the received system positioning control information. The system positioning control information and the positioning information are both sent in a short message format, that is, the system and the terminal complete information interaction depending on the short message format, and finally the purpose of reporting the positioning information by the terminal is achieved.
However, when the digital trunking communication system is in a communication state, that is, the terminal is in a call state, the terminal in the call state may not be able to receive and send short messages, and thus the purpose of reporting the positioning information by the terminal may not be achieved. The call state generally refers to a conventional group call state, and the conventional group call is a special PTT call. In order to solve the above problems, the prior art adopts a new format, namely Short Data Burst (SDB) to replace Short messages, as a carrier of system positioning control information and positioning information, so that the terminal in a call state can achieve the purpose of reporting the positioning information, but the SDB is only suitable for the case that the terminal sends the system positioning control information or the positioning information in the call state. In this document, a call state of the terminal is referred to as a traffic state, and a non-call state of the terminal is referred to as an idle state.
The key of the current problem is that the terminal may change its state at any time when the base station scheduling subsystem performs information interaction with the terminal, for example, from an idle state to a service state; if the base station scheduling subsystem and the terminal still adopt the short message format for information interaction at this time, the terminal in the service state may not be able to report the positioning information, and vice versa.
Disclosure of Invention
In view of the above, the present invention provides a method and an apparatus for reporting positioning information by a terminal in a digital trunking communication system, so that the terminal can report the positioning information no matter in an idle state or a traffic state.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:

The system positioning control information comprises a command which is periodically reported; correspondingly, before reporting the positioning information in each period, the terminal judges whether the terminal is in a service state at present, and if so, the terminal reports the positioning information in a short data burst format; otherwise, reporting the positioning information of the short message format.
Before the terminal reports the positioning information, the method further includes: the terminal judges whether the terminal is in a service state at present, if so, the terminal sends a response message in a short data burst format; otherwise, the terminal sends a response message in a short message format.
Wherein the positioning information is received by the terminal from a global positioning system satellite.
A device for reporting positioning information by a terminal in a digital trunking communication system comprises a system positioning control information sending module, a positioning information sending module and a positioning information receiving module; wherein,
the system positioning control information sending module is used for sending the system positioning control information in the short data burst format when the terminal is in a service state; or when the terminal is in an idle state, sending system positioning control information in a short message format;
the positioning information sending module is used for judging the state of the terminal after receiving the system positioning control information sent by the system positioning control information sending module, sending the positioning information of the terminal in the short data burst format when the terminal is in a service state, and sending the positioning information of the terminal in the short message format when the terminal is in an idle state;
and the positioning information receiving module is used for receiving the positioning information of the terminal sent by the positioning information sending module.
Wherein the positioning information sending module further comprises: a terminal state judgment submodule and a positioning information sending submodule; wherein,
the terminal state judging submodule is used for judging whether the terminal is in a service state or an idle state;
and the positioning information sending submodule is used for sending the positioning information of the terminal in the short data burst format when the terminal judging submodule determines that the terminal is in a service state, and sending the positioning information of the terminal in the short message format when the terminal judging submodule determines that the terminal is in an idle state.

and the response message receiving module is used for receiving the response message sent by the response message module.
The response message sending module is located in the terminal, and the response message receiving module is located in the base station scheduling subsystem.
Compared with the prior art, the technical scheme of the invention can see that the prior art does not judge the current state of the terminal before sending the system positioning control information or the positioning information, so that the format of sending the system positioning control information or the positioning information is fixed, and the sending format is not consistent with the current state of the terminal, which may result in that the system positioning control information or the positioning information cannot be received, and finally the terminal cannot realize the report of the positioning information. However, the present invention judges the current state of the terminal before sending any message, and adjusts the sending format in time according to the current state of the terminal, thereby ensuring that the system positioning control information or the positioning information can be received, and finally realizing the report of the positioning information no matter the terminal is in an idle state or a service state.

Detailed Description
The basic idea of the invention is: whether the base station scheduling subsystem sends the system positioning control information to the terminal or the terminal sends the positioning information to the base station scheduling subsystem, the corresponding sending format is selected according to the current state of the terminal, so that the terminal can receive the system positioning control information or the base station scheduling subsystem can receive the positioning information, and the terminal can report the positioning information no matter in an idle state or a service state.
The technical scheme of the invention is further elaborated in the following by combining the attached drawings.
As shown in fig. 1, the method for reporting positioning information by a terminal in a digital trunking communication system of the present invention includes the following steps:
step 101-103, the base station scheduling subsystem judges whether the terminal is in a service state currently, if so, the base station scheduling subsystem sends system positioning control information in an SDB format to the terminal to order the terminal to report the current positioning information of the terminal; otherwise, the base station scheduling subsystem sends system positioning control information in a short message format to the terminal so as to instruct the terminal to report the current positioning information of the terminal;
here, the content of the system positioning control information after being analyzed by the terminal is the same regardless of the format of the transmitted system positioning control information.
And 104-106, after receiving the system positioning control information, the terminal sends a response message to the base station scheduling subsystem according to the protocol specification to confirm the receipt of the system command. Before sending the response message, the terminal judges whether the terminal is in a service state at present, if so, the terminal sends the response message in an SDB format to the base station scheduling subsystem, otherwise, the terminal sends the response message in a short message format to the base station scheduling subsystem.
Step 107-109, after sending the response message to the base station scheduling subsystem, the terminal firstly judges whether the terminal is currently in a service state before reporting the self positioning information, if so, the terminal reports the self positioning information to the base station scheduling subsystem in an SDB format; otherwise, the terminal reports the positioning information of the short message format to the base station scheduling subsystem.
Wherein the terminal's own positioning information is received from GPS satellites by a GPS module in the terminal.
In addition, the system positioning control information sent by the base station scheduling subsystem to the terminal may include a single reporting or a periodic reporting command. If the system positioning control information contains a single reporting command, the terminal immediately reports the self positioning information by adopting a corresponding SDB format or a short message format according to the current state of the terminal after receiving the system positioning control information. If the system positioning control information contains a periodically reported command, the periodically reported command further contains a reported starting time, a reported ending time and a reported interval duration, the terminal can automatically judge the reporting time according to the periodically reported command, and before reporting the positioning information periodically each time, the terminal needs to judge the current state of the terminal and then selects a format for reporting the positioning information according to the determined state. From the above analysis, it can be seen that the present invention has two modes of reporting the positioning information in practical application, namely, real-time reporting and periodic reporting.
The technical proposal can find that the base station scheduling subsystem judges the state of the terminal before the information interaction is carried out with the terminal every time, and then selects to adopt the SDB format or the short message format to send the information according to the current state of the terminal, thereby realizing the report of the positioning information no matter the terminal is in an idle state or a service state.
In order to implement the method for reporting the positioning information by the terminal, the present invention further provides a device for reporting the positioning information by the terminal in the digital trunking communication system, as shown in fig. 2, the device includes: a system positioning control information sending module 10, a positioning information sending module 50 and a positioning information receiving module 30; wherein,

In addition, the positioning information transmitting module 50 further includes: a terminal state judgment submodule and a positioning information sending submodule; the terminal state judgment submodule is used for judging whether the terminal is in a service state or an idle state; the positioning information sending submodule is used for sending the positioning information of the terminal in the short data burst format when the terminal judging submodule determines that the terminal is in a service state, and sending the positioning information of the terminal in the short message format when the terminal judging submodule determines that the terminal is in an idle state.
The device further comprises: a response message sending module 40 and a response message receiving module 20; wherein,
