Indoor location server provision and discovery
Techniques are presented for receiving, at a discovered secure user platform location (SUPL) server (D-SLP) a request from a device for authorization to access a second D-SLP, where the D-SLP provides location services to a first service area comprising a venue or building. The second D-SLP provides location services to a second service area larger than the first service area authenticating information from a Home SLP (H-SLP) received as part of the request to access the second D-SLP. Techniques involve communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.
1. A method comprising:
receiving, at a discovered secure user platform location (SUPL) server (D-SLP) a request from a device for authorization to access a second D-SLP, wherein the D-SLP provides location services to a first service area comprising a venue or building, and the second D-SLP provides location services to a second service area larger than the first service area;
authenticating information from a home SLP (H-SLP) received as part of the request to access the second D-SLP; and
communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.
2. A method of claim 1 wherein the authorization to access the second D-SLP comprises an authorization time limit.
3. A method of claim 1 wherein the authorization to access the second D-SLP comprises an authorization area limit that limits access by the device to assistance data (AD) for a predefined area.
4. A discovered secure user platform location (SUPL) server (D-SLP) comprising:
means for receiving, at the D-SLP a request from a device for authorization to access a second D-SLP, wherein the D-SLP provides location services to a first service area comprising a venue or building, and the second D-SLP provides location services to a second service area larger than the first service area;
means for authenticating information from a home SLP (H-SLP) received as part of the request to access the second D-SLP; and
means for communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.
5. The D-SLP of claim 4 further comprising:
means for determining a time limit associated with the authenticating information from the H-SLP.
6. The D-SLP of claim 4 further comprising:
means for identifying an advertising server to provide advertising information to the device as part of the authorization to access the second D-SLP.
7. A non-transitory computer readable instruction medium comprising instructions that, when executed by a processor perform a method comprising:
receiving, at a discovered secure user platform location (SUPL) server (D-SLP) a request from a device for authorization to access a second D-SLP, wherein the D-SLP provides location services to a first service area comprising a venue or building, and the second D-SLP provides location services to a second service area larger than the first service area;
authenticating information from a home SLP (H-SLP) received as part of the request to access the second D-SLP; and
communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.
8. The non-transitory computer readable instruction medium of claim 7 wherein the method further comprises:
communicating a set of authorized assistance data functions associated with the first D-SLP to the device.
9. The non-transitory computer readable instruction medium of claim 8 wherein the method further comprises communicating a SUPL end message with the authorization to access the second D-SLP.
10. A discovered secure user platform location (SUPL) server (D-SLP) providing location services to a first service area comprising a venue or building, the D-SLP comprising:
a memory; and
a processor coupled to the memory, wherein the processor is configured to:
receive a SUPL start message from a device initiating a SUPL session;
receive a request from the device for authorization to access a second D-SLP as part of the SUPL session, the second D-SLP providing location services to a second service area larger than the first service area;
authenticate information from a home SLP (H-SLP) received as part of the request to access the second D-SLP; and
communicate an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP as part of the SUPL session.
11. The D-SLP of claim 10 wherein the processor is further configured to:
address a database of SLP relationships to verify the information from the H-SLP.
12. The D-SLP of claim 10 wherein the processor is further configured to communicate a message to the H-SLP as part of the authentication of the information from the H-SLP; and
receive a verification message from the H-SLP as part of the authentication of the information from the H-SLP.
