Abstract

A system, computer software and method for collecting, in addition to position data, additional positioning data in a user terminal served by a communication network. The method includes initiating, by generating a message within the user terminal, collection of the positioning data, where the positioning data includes information based on which a physical location of the user terminal is determined; measuring, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message; producing, within the user terminal, measurement reports that include the at least one parameter; selecting, within the user terminal, one or more measurement reports that were generated in response to the message generated by the user terminal; reporting the selected one or more measurement reports to an interface within the user terminal; and transmitting, from the interface, the reported one or more measurement reports to an external server or to the communication network.

Claims

1. A method performed by a user terminal served by a communication network, the method comprising:

initiating, by generating a message within the user terminal, collection of additional positioning data, wherein the additional positioning data is in addition to position data and includes information based on which a physical location of the user terminal is determined, and wherein the message includes an identity used for user terminal interface initiated requests;

determining, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message;

generating, within the user terminal, one or more output messages that include the at least one parameter;

selecting, within the user terminal based on the identity used for user terminal interface initiated requests, an output message that was generated in response to the message generated by the user terminal; and

transmitting the selected output message to an external server or to the communication network.

2. The method of claim 1, wherein initiating comprises:

injecting the message into a stream of messages received by the user terminal from the communication network.

3. The method of claim 1, wherein initiating comprises:

generating the message independent of any message received from the external server or the communication network.

4. The method of claim 1, further comprising:

determining, by the user terminal, another parameter related to the physical location of the user terminal in response to a request from the communication network.

5. The method of claim 4, wherein the another parameter is one of a cell ID, broadcast information received by the user terminal from a cell, quantized path loss of a received signal, signal strength, quantized noise rise, radio connection information, and quantized time.

6. The method of claim 1, wherein the at least one parameter is related to SFN-SFN type 1 or 2 measurements, E-OTD measurements, or inter-radio access technology measurements.

7. The method of claim 1, further comprising:

providing information to the external server or to the communication network to build a database of fingerprinted positions, the provided information being assembled based on the position data, which includes assisted global positioning information, and the at least one parameter, wherein the position data and the at least one parameter are measured simultaneously and sent together to the external server or to the communication network.

8. The method of claim 1, wherein the physical position of the user terminal is determined in the external server, based only on the additional positioning data transmitted from the user terminal.

9. The method of claim 1, further comprising:

measuring the at least one parameter when receiving the message generated within the user terminal and when receiving a message from the communication network.

10. A user terminal configured to be served by a communication network, the user terminal comprising:

processing circuitry configured to;

initiate, by generating a message within the user terminal, collection of additional positioning data, wherein the additional positioning data is in addition to position data and includes information based on which a physical location of the user terminal is determined, and wherein the message includes an identity used for user terminal interface initiated requests,

determine at least one parameter related to the physical location of the user terminal in response to the message,

generate one or more output messages that include the at least one parameter, and

select, within the user terminal based on the identity used for user terminal interface initiated requests, an output message that was generated in response to the message generated by the user terminal; and

a transceiver connected to the processing circuitry and configured to transmit the selected output message to an external server or to the communication network.

11. The user terminal of claim 10, wherein the processing circuitry is further configured to inject the message into a stream of messages received by the user terminal from the communication network.

12. The user terminal of claim 10, wherein the processing circuitry is further configured to determine another parameter related to the physical location of the user terminal in response to a request from the communication network.

13. The user terminal of claim 12, wherein the another parameter is one of a cell ID, broadcast information received by the user terminal from a cell, quantized path loss of a received signal, signal strength, quantized noise rise, radio connection information, and quantized time.

14. The user terminal of claim 10, wherein the message is generated independent of any message received from the external server or the communication network.

15. The user terminal of claim 10, wherein the at least one parameter is related to SFN-SFN type 1 and/or 2 measurements, E-OTD measurements, or inter-radio access technology measurements.

16. The user terminal of claim 10, wherein the transceiver is further configured to:

provide information to the external server or to the communication network to build a database of fingerprinted positions, the provided information being assembled based on the position data, which includes assisted global positioning information, and the at least one parameter, wherein the position data and the at least one parameter are measured simultaneously and sent together to the external server or to the communication network.

17. The user terminal of claim 10, wherein the external server determines the physical position of the user terminal based only on the additional positioning data transmitted from the user terminal.

18. The user terminal of claim 10, wherein the processing circuitry is further configured to measure the at least one parameter when receiving the message generated within the user terminal and when receiving a message from the communication network.

19. A user terminal configured to be served by a communication network, the user terminal comprising:

processing circuitry configured to;

initiate, by generating a message within the user terminal, collection of additional positioning data, wherein the additional positioning data is in addition to position data and includes information based on which a physical location of the user terminal is determined, and wherein the message includes an identity used for user terminal interface initiated requests,

receive an output message at the user terminal interface that includes at least one parameter related to the physical location of the user terminal in response to the message, wherein the output message to be received by the interface is selected based on the identity used for user terminal interface initiated requests; and

a transceiver configured to transmit the output message that includes at least one parameter related to the physical location of the user terminal to an external server or to the communication network.
