Description

A mobile terminal positioning method and mobile terminal

technical field

The invention relates to a terminal positioning technology in the communication field, in particular to a condition-triggered mobile terminal positioning method and a mobile terminal.

technical background

Network-based positioning technology, such as the technology of jointly positioning the current location of mobile terminals through base stations, can theoretically reach a range of 50 meters, but due to the complex urban environment, it can only reach a range of 200 meters in practice. The positioning technology based on GPS can theoretically reach 10 meters. However, in places with a large urban environment, especially indoors, its positioning accuracy cannot be guaranteed. None of these positioning technologies can be well applied to specific application occasions. For example, after a user arrives at an office, he allows his mobile terminal to execute a call transfer setting command to transfer the call to the office phone. Because, if base station positioning or GPS positioning is used, it is impossible to accurately locate the relatively small area of the office.

At present, there is also a positioning technology based on object identification and identification, see the invention with the application number 02125256.4 and the invention name "A Method for Identification and Identification of Physical Objects". The technical solution is to set up a wireless identification module for Identify a physical object, which stores the identification information of the identification module and the identified object; set up an identification module for identifying the identification module; when the identification module and the identification module are used specifically, the identification module searches for the identification module, and if found, obtains the identification According to the identification information stored in the module, relevant location information can be obtained; when the wireless connection between the identification module and the identification module is cut off, it is considered that the identification module has left the identification module. The method is accurate in positioning (can reach within 3 meters, or even a smaller range). According to the positioning technology, various services for the mobile phone adaptation environment can be realized, such as automatic call transfer setting and cancellation of the mobile phone.

However, when this positioning technology is applied to services such as automatic call forwarding settings of mobile terminals, it is necessary for the mobile terminal to search continuously to realize automatic call forwarding settings. At this time, the mobile terminal will The power of the mobile terminal is consumed by the identification module, especially when the mobile terminal does not enter the identification range of an identification module at all, such loss will be meaningless. Obviously, if real-time performance is to be achieved in this positioning method, it will lead to consumption of terminal resources.

Contents of the invention

The purpose of the present invention is to provide a positioning method that can perform positioning accurately and with low consumption.

For this reason, the present invention adopts following technical scheme:

A positioning method for a mobile terminal, wherein an identification module and an identification module are respectively set on the positioning reference object and the mobile terminal, and the identification module is used to identify the identification module; it is characterized in that it also includes:

A trigger module is set in the mobile terminal, and an object recognition trigger condition is set in the trigger module, and when it is detected that the trigger condition is satisfied, the recognition module is driven to perform corresponding operations.

The corresponding operation includes that the identification module starts to identify the identification module or the identification module stops identifying the identification module.

The trigger condition is that the location area information of the mobile terminal satisfies a preset condition.

The detection is performed when the location area information of the mobile terminal changes.

A corresponding relationship table between the location area and the identification module is set in the identification module, and the identification module searches for the identification module through the corresponding relationship table.

The location area information is the location information of the handheld phone system; or the location information of the mobile network of the mobile terminal; or the location information of the wireless local area network of the mobile terminal.

The location information is the base station code of the handheld telephone system; or the base station code of the mobile network; or the access point code of the wireless local area network.

The trigger condition is the occurrence information of a special state.

A mobile terminal implemented according to the above method includes a mobile terminal body with a control module and an identification module arranged on the mobile terminal body, the identification module receives the control signal of the control module, and is connected with the positioning reference object The identification module communicates to locate the mobile terminal. The mobile terminal also includes a trigger module provided with an object recognition driving trigger condition. The trigger module sends a trigger signal to the control module, and the control module controls the identification module to perform corresponding operations.

The trigger module can be set separately, or can be set in the control module of the mobile terminal.

Through the joint positioning method and device, the mobile terminal does not need to turn on the identification function all the time, which reduces the energy consumption of the mobile terminal and prolongs the standby time.

Detailed ways

The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural diagram of a mobile terminal of the present invention, as can be seen from the figure, the mobile terminal includes:

The mobile terminal body is provided with a control module on the mobile terminal body, and the control module controls various operations of the mobile terminal;

The identification module arranged on the mobile terminal body, the identification module receives the control signal of the control module, and communicates with the identification module provided on the positioning reference object to locate the mobile terminal; the control signal includes driving the identification module to start identifying the identification module , and the drive identification module terminates the identification identification module;

Trigger module: set the trigger condition for object recognition drive, the trigger module sends a trigger signal to the control module to control the recognition module to perform corresponding operations. The trigger signal includes trigger information such as condition fulfillment and condition dissatisfaction.

The trigger module can be set separately, or can be set in the control module of the mobile terminal.

When adopting the technical solution of the present invention to perform positioning, as shown in Figure 2, it can be set as follows:

First, make the following settings for the mobile terminal and the positioning reference object respectively:

On the positioning reference object, an identification module is set, and the identification module is used to identify a specific positioning reference object. The number of the identification modules can be set to be multiple, so that different identification modules can be set in different geographic locations, and the mobile terminal can locate different places respectively.

An identification module is set on the mobile terminal, the identification module corresponds to the identification module, and the identification module can be searched and identified through wireless signals. For the identification module and identification module technology, please refer to the patent application with the application number 02125256.4 and the title of the invention "A Method for Identification and Identification of Physical Objects", which will not be described in detail herein.

The above-mentioned mobile terminal may be a mobile phone, a handheld computer (PDA), a portable computer, a personal computer (PC) and the like.

In the mobile terminal, a driving trigger condition is set, and according to whether the driving trigger condition is satisfied, it is determined to enable or disable the identification function of the identification module on the driving mobile terminal.

The above-mentioned driving trigger conditions may be various, and different settings may be made according to different requirements.

For example, the driving trigger condition can be set to enable or disable the identification function of the identification module after the mobile terminal receives an operation command from the user. For example, it is set that the user presses a special button to send a command to the mobile terminal, and the mobile terminal activates or deactivates the corresponding identification function after receiving the command. Of course, it is also possible to increase the start/close recognition function in a mobile terminal operation menu. When the operation menu is "start recognition function", when the menu command is executed, the mobile terminal control module starts the recognition module recognition function, and the menu is set to "Turn off the recognition function"; on the contrary, when executing the command "Turn off the recognition function" of the menu, the mobile terminal control module will close the recognition function of the recognition module, and reset the menu to "Start the recognition function".

The trigger condition can be set as the mobile terminal enters or leaves a location area, that is, the current location area information of the mobile terminal satisfies the preset location area, or after the condition is met, the current location area information is changed due to the mobile location. The preset location area is not met anymore. In this way, when the user enters or leaves a location area, the function of identifying the identification module is activated or deactivated. For example, the user can obtain the location area code of the office site and save it in the mobile terminal. When the mobile terminal updates its location, it can detect whether it has entered the office site by comparing the saved location area code with the current location area code. If yes, the entry trigger condition is satisfied, and at this time, the mobile terminal starts the corresponding identification function. If leaving the location area of the office site, the leaving trigger condition is met, and the mobile terminal turns off the identification function.

The location update may refer to the location update of the mobile terminal in the communication network; it may also refer to the location update in the wireless local area network (WLAN). The mobile terminal knows that it has entered a new location area by receiving location update information delivered by the network.

The communication network may be a mobile communication network, such as a Handy Phone System (PHS) network, a Global System for Mobile Communications (GSM) network, a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, etc.) or a wireless LAN.

The mobile terminal may detect whether the new location area satisfies a preset trigger condition when the information of the current location area changes. For example, due to roaming, the mobile terminal finds that the current cell information has changed, or that the base station code information has changed, or that the WLAN access point AP code information has changed. At this time, the mobile terminal detects whether the new location area information meets the predetermined requirements. The set trigger condition, that is, whether it is a preset location area, if yes, then the condition for entering the location area is satisfied, at this time, the mobile phone drive identification module starts to identify the identification module; if the mobile terminal detects that the new location area information does not meet The preset trigger condition, that is, the current location area information is not the preset location area, then the mobile phone judges whether the identification module is in the identification state, and if so, terminates the identification operation of the identification module.

When multiple identification modules are set, correspondingly, you can also set the corresponding relationship table between the location area and the identification module, as shown in the following table: Location Area ID Identification module ID Identify object name Cell 1 code HomeID Home Location Area 2 Code OfficeID office Cell 3 code ClassroomID classroom WLAN access point AP1 encoding ChurchID church WLAN access point AP2 encoding CinemaID cinema

The area ID in the above table can be composed of area type plus area code. For example, the cell area type can be set to 1, and the area type of the AP coverage area can be set to 2.

In this way, when the mobile terminal enters a set location area, the identification module is started to search for the identification modules, and those designated identification modules corresponding to the location area are searched.

The identification module terminates the identification when identifying a set identification module. At this time, the identification module of the mobile terminal only periodically detects whether it has left the identification range of the identification module (that is, the effective wireless signal range), and The search for new identity modules is not continued. Here, it further includes judging whether the current location area is the set location area when leaving the identification range of the identification module, and if so, re-entering the identification state.

The identification module terminates the identification when it recognizes all the identification modules corresponding to the current location area. At this time, the identification module of the mobile terminal only periodically detects whether it leaves the identification range of these identification modules (that is, the effective wireless signal range) ) without continuing to search for new identity modules. Here, when leaving the identification range of one of the identification modules, it is judged whether the current location area is the set location area, and if so, the identification state is re-entered.

The trigger condition can also be that the mobile terminal detects the occurrence of a special state. For example, for a mobile terminal provided with a noise detection function, it can be set to start the identification function when the detected noise reaches a certain decibel.

For example, when "the location area information is the area where the office is located" is set as the trigger condition, the mobile terminal saves the location area information of the office, so that the next time the mobile terminal receives the location update information from the network, it will be an entry into the office. When the location area is located, that is, when the received location area information becomes the location area where the saved office is located, the identification function is activated to search for the identification module of the set office, so as to find a matching identification module. For example, in the place where positioning is required, the information of the corresponding community is obtained and saved, and an identification module is set in these places; when the mobile phone roams to the community next time, the communication network will transmit the community number to the mobile phone, and the mobile phone will , for comparison, if it is found, it means that the mobile phone may enter the place that needs to be positioned, and then start to perform the positioning function, that is, start the identification module to search for the identification module, so as to find the place to be positioned.

The following takes the Global System for Mobile Communications (GSM) as an example. In the GSM mobile phone system, its coverage is divided into several location areas. The location area is used to identify the location in the mobile network where the user is located. Each location area has a unique identifier LAI (Location Area Code), which can identify different location areas in different networks in different countries. The identity of the location area consists of the following:

LAI＝MCC+MNC+LAC

in:

MCC is the country code of the mobile communication network, which distinguishes the country to which the network belongs;

MNC is the mobile network code, which distinguishes different GSM mobile communication networks in a country;

LAC is a location area code, which is used to identify different location areas in a GSM network.

The ID of the location area is broadcast on the broadcast channel of the system, and all mobile phones within the coverage area of the system can receive this information, so as to know the current location of the mobile phone.

Each location area is composed of several cells, and the area range can be further narrowed by the cell identification number. That is, the location area can be indicated by the identifier of the location area, or by the identifier of the cell under the location area.

The location area can also be represented by a base station code. In this case, the network is required to transmit the identity of the base station to the mobile terminal. In this way, the location area range is the range within which the base station code transmitted by the base station can be received.

For WLAN, the location area identifier may be the code of the corresponding access point (AP). In this way, the location area range is the range within which the AP-coded signal transmitted by the AP can be received.

For the Handy Phone System (PHS), the location area identifier may be the code of the corresponding PHS base station, or the code of the corresponding cell. In this way, the location area range is the range within which the base station code transmitted by the PHS base station can be received.

The above trigger condition may also be a composite condition. For example, the set trigger condition may be that the code of the location area is the code of the area where the office is located, and at the same time, the decibel value of the noise detected by the mobile phone is lower than a certain value.

The terminal of the present invention automatically obtains positioning information of a large area through a large network, and further judges whether to activate the active positioning function of a small area according to the positioning information of a large area. Through this joint positioning method, the mobile terminal does not need to turn on the identification function all the time, which reduces the energy consumption of the mobile terminal and prolongs the standby time.
