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 an external location server to the mobile unit while the mobile unit is indoors. The indoor mobile unit positioning includes mobile unit-based positioning which makes use of reception of access point signals by the mobile unit.

Claims

1. A method for supplying a location based service or location based application generated in an outdoor environment to a mobile unit positioned in an indoor environment, comprising the steps of:

a) determining the mobile unit location by access point (AP)-based positioning;

b) relaying data related to the mobile unit location through a distributed antenna system (DAS) to an external location server (ELS) by transmitting the data through a cellular communication link;

c) providing the location based service or location based application generated in the outdoor environment from the ELS to the mobile unit;

d) toggling the determining the mobile unit location from AP-based positioning to external network-based positioning when the mobile unit moves from the indoor environment to an outdoor environment; and

e) toggling the determining of the mobile unit location from external network-based positioning to AP-based positioning when the mobile unit moves from the outdoor environment to the indoor environment,

wherein the cellular communication link includes a cellular network coupled to the DAS through a base server.

2. The method of claim 1, wherein the AP-based positioning includes mobile unit-based positioning using AP signals.

3. The method of claim 1, wherein the AP-based positioning includes AP network-based positioning.

4. The method of claim 1, wherein the step of providing includes providing the location based service or location based application through a cellular communication link.

5. The method of claim 4, wherein the cellular communication link includes a cellular network coupled to the DAS through a repeater.

6. The method of claim 1, wherein the step of providing includes providing the location based service or location based application through a cellular network coupled to a public network.

7. The method of claim 1, wherein the data related to the mobile unit location includes a description of an indoor entity of the indoor environment.

8. The method of claim 7, wherein the indoor entity is selected from the group consisting of an area, a floor, a hall and a room.

9. The method of claim 1, further comprising the step of distributing an overlay AP signal through the DAS to the mobile unit.
