Abstract

An Internet protocol low noise block downconverter (IP LNB), which may be within a satellite reception assembly, may be operable to determine location information and time information of the IP LNB, and may communicate the determined location information and the corresponding time information to a wireless communication device communicatively coupled to the IP LNB. The communicated location information may be configured to enable the wireless communication device to determine its location based on the determined location information and the corresponding time information. The IP LNB may determine the location information and/or the time information of the IP LNB based on global navigation satellite system (GNSS) signals, which may be received via the satellite reception assembly and may be processed via the IP LNB. The IP LNB may provide services based on the determined location information and/or the determined time information of the IP LNB.

First claim

What is claimed:

1. A method, comprising:
determining in an Internet protocol low noise block downconverter (IP LNB) that is within a satellite reception assembly, location information and corresponding time information of the IP LNB;
determining location information of a wireless source device based on the determined location information and the corresponding time information of the IP LNB along with a plurality of other location information and corresponding other time information associated with a plurality of other IP LNB assemblies; and
communicating the determined location information and the corresponding time information to a wireless communication device communicatively coupled to the IP LNB;
wherein:
the location information is configured to enable the wireless communication device to determine its location based on the determined location information and the corresponding time information;
the plurality of other IP LNB assemblies are communicatively coupled to the IP LNB; and
the time information and each of the other time information are determined based on receiving a corresponding signal from the wireless source device.

2. The method of claim 1 , comprising determining the location information and/or the time information of the IP LNB based on global navigation satellite system (GNSS) signals.

3. The method of claim 2 , comprising receiving and/or processing the global navigation satellite system (GNSS) signals by the IP LNB.

4. The method of claim 1 , comprising:
receiving the location information of the wireless communication device from the wireless communication device; and
storing the received location information of the wireless communication device.

5. The method of claim 1 , comprising communicating the determined time information to one or more other IP LNB assemblies for accurate timing recovery.

6. The method of claim of 1 , comprising providing services based on the determined location information and the corresponding time information.

7. The method of claim 1 , comprising applying digital rights management (DRM) and/or conditional access (CA) for content delivery based on the determined location information of the IP LNB.

8. The method of claim 1 , comprising generating a location map for a region based on the determined location information of the IP LNB along with other location information associated with other IPLNB assemblies.

9. The method of claim 1 , comprising detecting relocation of the satellite reception assembly and/or an associated gateway based on the determined location information of the IP LNB.

10. A system, comprising:
an Internet protocol low noise block downconverter (IP LNB) within a satellite reception assembly, wherein the IP LNB comprises at least one processing circuit for processing data and at least one communication circuit for use in support of communication of signals, the IP LNB being operable to:
determine location information and corresponding time information of the IP LNB; and
determine location information of a wireless source device based on the determined location information and the corresponding time information of the IP LNB along with a plurality of other location information and a plurality of corresponding other time information associated with a plurality of other IP LNB assemblies; and
communicate the determined location information and the corresponding time information to a wireless communication device communicatively coupled to the IP LNB; and
wherein:
the determined location information is configured to enable the wireless communication device to determine its location based on the determined location information and the corresponding time information;
the plurality of other IP LNB assemblies are communicatively coupled to the IP LNB; and
the time information and each of the other time information are determined based on receiving a corresponding signal from the wireless source device.

11. The system of claim 10 , wherein the IP LNB is operable to determine the location information and/or the time information of the IP LNB based on global navigation satellite system (GNSS) signals.

12. The system of claim 11 , wherein the IP LNB is operable to receive and/or process the global navigation satellite system (GNSS) signals.

13. The system of claim 10 , wherein the IP LNB is operable to:
receive the location information of the wireless communication device from the wireless communication device; and
store the received location information of the wireless communication device.

14. The system of claim 10 , wherein the IP LNB is operable to communicate the determined time information to one or more other IP LNB assemblies for accurate timing recovery.

15. The system of claim 10 , wherein the IP LNB is operable to provide services based on the determined location information and the corresponding time information.

16. The system of claim 10 , wherein the IP LNB is operable to apply digital rights management (DRM) and/or conditional access (CA) for content delivery based on the determined location information of the IP LNB.

17. The system of claim 10 , wherein the IP LNB is operable to generate a location map for a region based on the determined location information of the IP LNB along with other location information associated with other IPLNB assemblies in the region.

18. The system of claim 10 , wherein the IP LNB is operable to detect relocation of the satellite reception assembly and/or an associated gateway based on the determined location information of the IP LNB.
