## Abstract

Location information (e.g., GPS information) pertaining to the location of a device may be integrated into a distributed antenna system (DAS) to enhance location based services. This may be accomplished via a system that filters and combines GPS information with DAS information. Utilization of the enhanced location based services system may enhance accuracy performance of indoor location services and improve round-trip time (RTT) location responses associated with network assisted GPS (e.g., A-GPS) location requests for services from indoor calls.

## Claims

### Claim 1

A device comprising:
a processor; and
memory coupled to the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving an indication of a call;
responsive to receiving the indication of the call, obtaining location information pertaining to a location of a source of the call;
providing a location signal;
receiving, from a plurality of transceivers, a respective plurality of responses to the provided location signal;
determining a time at which each response of the plurality of response was received;
determining a location of each of the plurality of transceivers;
determining a calculated location of the source of the response based on the determined time at which each response of the plurality of response was received and the location of each of the plurality of transceivers;
augmenting the location information with the calculated location;
receiving information to be distributed via a distributed antenna system;
generating combined information by combining the received location information and the information to be distributed via the distributed antenna system; and
providing the combined information via the distributed antenna system.

### Claim 2 (depends on 1)

The device of claim 1, wherein the location information comprising signals from a global position system satellite.

### Claim 3 (depends on 1)

The device of claim 1, wherein:
an intended recipient of the location information is a mobile device; and
an intended recipient of the information to be distributed via the distributed antenna system is not the mobile device.

### Claim 4 (depends on 1)

The device of claim 1, the operations further comprising:
incorporating topographical information pertaining to an environment proximate to the source of the call into the combined information.

### Claim 5 (depends on 4)

The device of claim 4, wherein the topographical information comprises a blueprint of the environment proximate to the source of the call.

### Claim 6 (depends on 4)

The device of claim 4, wherein the topographical information comprises a location of a global positioning antenna from which the location information was sent.

### Claim 7

(canceled)

### Claim 8

A device comprising:
a processor; and
memory coupled to the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
initiating a call;
responsive to initiating the call, receiving location information pertaining to a location of the device;
providing a location signal;
receiving, from a plurality of transceivers, a respective plurality of responses to the provided location signal;
determining a time at which each response of the plurality of response was received;
determining a location of each of the plurality of transceivers;
determining a calculated location of the source of the response based on the determined time at which each response of the plurality of response was received and the location of each of the plurality of transceivers;
augmenting the location information with the calculated location;
receiving topographical information pertaining to an environment proximate to the device;
combining the location information with the topographical information; and
rendering an indication of the combined information.

### Claim 9 (depends on 8)

The device of claim 8, wherein the location information comprising signals from a global position system satellite.

### Claim 10 (depends on 8)

The device of claim 8, wherein the topographical information comprises a blueprint of the environment proximate to the source of the call.

### Claim 11 (depends on 8)

The device of claim 8, wherein the topographical information comprises a location of a global positioning antenna from which the location information was sent.

### Claim 12

(canceled)

### Claim 13 (depends on 8)

The device of claim 8, wherein:
the indication of the combined information is rendered visually as an overlay of a visual representation of the topographical information.

### Claim 14

A computer-readable storage medium comprising executable instructions that when executed by a processor cause the processor to effectuate operation comprising:
receiving an indication of a call;
responsive to receiving the indication of the call, obtaining location information pertaining to a location of a source of the call;
providing a location signal;
receiving, from a plurality of transceivers, a respective plurality of responses to the provided location signal;
determining a time at which each response of the plurality of response was received;
determining a location of each of the plurality of transceivers;
determining a calculated location of the source of the response based on the determined time at which each response of the plurality of response was received and the location of each of the plurality of transceivers;
augmenting the location information with the calculated location;
receiving information to be distributed via a distributed antenna system;
generating combined information by combining the received location information and the information to be distributed via the distributed antenna system; and
providing the combined information via the distributed antenna system.
