Abstract

Methods and systems for indoor mobile unit positioning, for seamlessly toggling a mobile unit positioning between outdoor positioning and indoor positioning and for providing location based services or application generated by and external location server to the mobile unit while the mobile unit is indoors. The indoor mobile unit positioning includes mobile unit-based positioning with makes use of reception of access point signals by the mobile unit.

Claims

1. A system for supplying at least one of a location based service (LBS) and a location based application (LBA) generated by an external location server (ELS) in an outdoor environment to a mobile unit positioned in the indoor environment, comprising:

an access point (AP) network at least partially located in the indoor environment;

a distributed antenna system (DAS) at least partially located in the indoor environment and communicatively coupled to at least one of a base station and a repeater;

a location support module for acquiring and processing data related to the mobile unit location in the indoor environment; and

a cellular link for transmitting at least some of the data related to the mobile unit location to the ELS and for transmitting at least one of the LBS and the LBA from the ELS to the mobile unit,

wherein the location support module performs toggling between AP-based positioning and at least one of GPS-based positioning and AGPS-based positioning.

2. The system of claim 1, wherein when the mobile unit moves from the outdoor environment to the indoor environment, the location support module toggles from at least one of GPS-based positioning and AGPS-based positioning to AP-based positioning.

3. The system of claim 2, wherein when the mobile unit moves from the indoor environment to the outdoor environment, the location support module toggles to at least one of GPS-based positioning and AGPS-based positioning.

4. The system of claim 3, wherein the AP-based positioning includes AP network-based positioning.

5. The system of claim 3, wherein the data related to the mobile unit location includes a description of an indoor entity of the indoor environment.

6. The system of claim 5, wherein the indoor entity is selected from the group consisting of an area, a floor, a hall and a room.

7. The system of claim 3, wherein the system further comprises an overlay AP configured to provide a control channel to be broadcast through the DAS inside the indoor environment.

8. The system of claim 7, wherein the control channel is configured to transmit an offer to a mobile unit to join a LBS.

9. The system of claim 3, wherein the AP-based positioning includes mobile unit-based positioning using AP signals.

10. The system of claim 3, wherein the location support module is located in the mobile unit.

11. A system for supplying at least one of a location based service (LBS) and a location based application (LBA) generated by an external location server (ELS) to a mobile unit positioned in an indoor environment, comprising:

an access point (AP) network at least partially located in the indoor environment;

a location support module for acquiring and processing data related to the mobile unit location in the indoor environment; and

a cellular link for transmitting at least some of the data related to the mobile unit location to the ELS and for transmitting at least one of the LBS and the LBA from the ELS to the mobile unit, wherein

the location support module performs toggling from AP-based positioning to at least one of GPS-based positioning and AGPS-based positioning when the mobile unit moves from the indoor environment to an outdoor environment, and

the location support module performs toggling from at least one of GPS-based positioning and AGPS-based positioning to AP-based positioning when the mobile unit moves from the outdoor environment to an indoor environment.

12. The system of claim 11, wherein the system further comprises an overlay AP configured to provide a control channel inside the indoor environment, the control channel being configured to transmit an offer to a mobile unit to join a LBS.

13. The system of claim 12, wherein the data related to the mobile unit location includes a description of an indoor entity of the indoor environment, wherein the indoor entity is selected from the group consisting of an area, a floor, a hall and a room.

14. The system of claim 12, wherein the location support module is located in the mobile unit.

15. A system for supplying at least one of a location based service (LBS) and a location based application (LBA) generated by an external location server (ELS) to a mobile unit positioned in an indoor environment, comprising:

an access point (AP) network at least partially located in the indoor environment;

a distributed antenna system (DAS) at least partially located in the indoor environment and communicatively coupled to at least one of a base station and a repeater;

a location support module for acquiring and processing data related to the mobile unit location in the indoor environment; and

a cellular link for transmitting at least some of the data related to the mobile unit location to the ELS and for transmitting at least one of the LBS and the LBA from the ELS to the mobile unit, wherein

the location support module performs toggling from AP-based positioning to external network-based positioning when the mobile unit moves from the indoor environment to an outdoor environment, and

the location support module performs toggling from external network-based positioning to AP-based positioning when the mobile unit moves from the outdoor environment to an indoor environment.

16. The system of claim 15, wherein the system further comprises an overlay AP configured to provide a control channel to be broadcast through the DAS inside the indoor environment, the control channel being configured to transmit an offer to a mobile unit to join a LBS.

17. The system of claim 16, wherein the data related to the mobile unit location includes a description of an indoor entity of the indoor environment, wherein the indoor entity is selected from the group consisting of an area, a floor, a hall and a room.

18. The system of claim 16, wherein the location support module is located in the mobile unit.
