- the location service device 6 is further configured to compare whether the identifier of the to-be-queried cell is the same as the identifier of the cell where the first terminal is located, and when the same, send the cell location information to the cell location information requesting device 7. .
- another embodiment of the system for acquiring cell location information further includes: a second terminal 9.
- the second terminal 9 is configured to send the second location information of the second terminal in the cell to the location service device 6;
- the location service device 6 is further configured to generate third location information according to the first location information and the second location information, and update the cell location information by using the third location information. The more times the terminal is located in the same cell, the closer it is to the actual cell location information. Thus, the cell location information obtained by querying the location service device 6 is closer to the actual cell location information.
- the system for acquiring cell location information includes a terminal, a location service device, and a roaming location location device.
- the location service device sends the first location information and the identifier of the cell to the roaming location location collection device, and stores the location information in the roaming location collection device.
- the terminal is responsible for performing information interaction with the positioning service device. If it is the AGPS positioning mode, the terminal generates a positioning result by positioning the AGPS chip, and transmits the positioning result to the positioning service device.
- the location service device can provide location services, including privacy authentication for requesting location messages, location capability confirmation of the location terminal, and receiving and processing location service provider (SP) location requests.
- location services including privacy authentication for requesting location messages, location capability confirmation of the location terminal, and receiving and processing location service provider (SP) location requests.
- SP location service provider
- the roaming location location collecting device provides a roaming cell location query for the positioning service device, and has the function of updating the cell location information, and has a self-learning function, and can perform the cell location and the cell identifier returned by the positioning service device through a self-learning algorithm. Store or update to ensure the accuracy of the location of the roaming community.
- the location service device collects cell location information of the global mobile operator network through a self-learning method to implement AGPS or cell location of the terminal in a roaming state.
- Step 1 the positioning service device receives a positioning request message for a certain terminal. Then, if it is the AGPS positioning mode, the base station database is searched according to the CELL cell identification information carried by the terminal. If it is the cell positioning mode initiated by the positioning service provider, the positioning service device sends a message to the HLR to query the cell identity information of the located terminal. Then, the base station database is searched for by the cell identification information. If the cell location information is not found, the terminal roams out of the service range of the location service device, and then step 2 is performed.
- Step 2 The location service device searches for the location information corresponding to the cell identification information by the location device, and if found, returns the obtained location result to the location service device, and performs step 3, if not found. Then, the failure result is returned to the location service device, and step 4 is performed.
- Step 3 After receiving the location result, if the location service device is in the AGPS location mode, the location service device calculates the GPS assistance information to be sent to the terminal according to the location result, and interacts with the terminal, and the terminal completes the positioning process, and the location terminal will The location result is returned to the location service device, and the location service device sends the location result to the roaming location location collection device, and the roaming location location collection device updates the location information corresponding to the cell by using a certain algorithm.
- the operation of the roaming location location device to update the CELL location result is not a simple update location result, but uses a certain algorithm.
- the location service device When the collected location results of the same cell are more, the obtained cell location result is more accurate, and That is to say, the more the number of times the terminal is positioned, the closer it is to the actual CELL position. If it is a cell location mode, the location service device directly returns the location result to the location service provider, and the location process ends.
- Step 4 When the location service device does not obtain the location information corresponding to the current CELL of the terminal, if it is the AGPS positioning mode, the GPS satellite almanac is sent to the terminal, and the terminal locates the location result through its own GPS chip, and returns the location result to the location.
- the location service device the location service device sends a location result to the roaming location location collection device, and the roaming location location collection device stores the location result corresponding to the cell. If it is a cell location mode, the location service device returns a failure message to the location service provider.
- the present invention is applied to the location terminal roaming outside the service range of the location service device, and the AGPS and the cell location service can be provided by the assistance of the roaming location location device.
- the roaming location location collection device may be disposed in the location service device.
- the first terminal can be a mobile phone or the like.
- the positioning performed by the terminal may be a GPS positioning method or other positioning methods.
- Community The location information requesting device may be a positioning service provider, or may be a terminal or the like.
- the method embodiment is corresponding to the device embodiment, and the portion not described in detail in the method embodiment may refer to the description of the relevant part in the device embodiment, and the partial reference method not described in detail in the device embodiment.
- the description of the relevant parts in the embodiment can be.
- the steps of the foregoing embodiments may be implemented by a program to instruct related hardware, and the program may be stored in a computer readable storage medium.
- the method includes the steps of the foregoing method embodiment, such as: a magnetic disk, an optical disk, a read-only memory (ROM), or a random access memory (No. RAM) and so on.
- sequence numbers of the steps are not used to limit the sequence of the steps.
- the steps of the steps are performed without any creative labor. Variations are also within the scope of the invention.
- the present invention is applied to the location terminal to roam outside the service range of the location service device, and the AGPS and the cell location service can be provided by the assistance of the roaming location location device.
- the roaming location location device may be disposed in the location service device.
- the first terminal can be a mobile phone or the like.
- the positioning performed by the terminal may be a GPS positioning method or other positioning methods.
- the cell location information requesting device may be a positioning service provider, or may be a terminal or the like.
