In instances when the location/time service module 326 detects that the gateway 605 has been relocated or moved from the installed location 615 to, for example, an unauthorized location 625, the location/time service module 326 may communicate or report the unauthorized relocation of the gateway 605 to the satellite service provider 120. The satellite service provider 120 may then communicate or send a warning message indicating the unauthorized movement of the gateway 605 to a user and/or block all or partial programming, for example. In some instances, the satellite reception assembly 602 and/or the gateway 605 may be rendered inoperable by the satellite service provider 120, for example.
In an exemplary operation, the IP LNB assembly 300 and a plurality of other IP LNB assemblies 713, 723 located in certain proximity may each receive a signal from the wireless source device 190. The received signals may comprise time stamps information of the signals, for example. In such instances, based on determined time information while receiving the signals, a distance between the IP LNB assembly 300 and the wireless source device 190, a distance between the IP LNB assembly 713 and the wireless source device 190, and a distance between the IP LNB assembly 723 and the wireless source device 190 may be computed or estimated. The time of arrival of the received signal may be determined or estimated during processing of the received signal by the IP LNB module 308 in the IP LNB assembly 300, for example.
The location information and the distance information associated with the IP LNB assemblies 300, 713, 723 may then be utilized to determine or compute location information of the wireless source device 190. In this regard, for example, based on the location information and the distance information associated with the IP LNB assembly 300 along with the location information and the distance information associated with the IP LNB assemblies 713, 723, the location/time service module 326 in the IP LNB assembly 300 may be operable to determine or compute the location information of the wireless source device 190, locally. The location information of the wireless source device 190 may be computed by performing, for example, a trilateration or triangulation process. In some instances, the location information of the wireless source device 190 may be determined remotely via, for example, the location server 192. In this regard, the location server 192 may perform the trilateration or the triangulation processing on received location information and distance information associated with the IP LNB assemblies 300, 712, 723 to compute the location information for the wireless source device 190.
As more IP LNB assemblies participate in contributing signals, the accuracy level of the location information obtained from the trilateration or the triangulation processing may increase. The determined location information along with other characteristics (e.g., unprotected WiFi status, frequency offset, transmission frequency, estimated power levels) of the wireless source device 190 may be stored and maintained in the database 332 in the IP LNB assembly 300. In this regard, the database 332 may also store other location information and other characteristics associated with a plurality of other wireless source devices, for example. In such instances, the database 332 may be made available to other devices and/or other databases for the purpose of, for example, determining nearby hotspots positioning, time synchronization, hand-off, frequency allocation, frequency planning, coverage planning and analysis, traffic flow monitoring, as well as confirming device location to a third party for the purposes of security, delivery of location-based services and advertisement, and/or asset tracking.
In step 803, the location/time service module 326 in the IP LNB assembly 300 may be operable to provide services based on the determined location information and/or the determined time information. In this regard, for example, the location information and the time information may be communicated to a wireless communication device such as the wireless communication device 180 for determining location information of the wireless communication device 180. For example, the location/time service module 326 may perform digital rights management (DRM) and/or conditional access for content delivery based on the determined location information of the IP LNB assembly 300. The determined time information may be utilized for accurate timing recovery for a region such as the region 170, for example. The determined location information may be utilized for generating a location map for the region 170, for example. The location/time service module 326 may detect relocation or movement of the satellite reception assembly 604 and/or the gateway 605 based on the determined location information of the IP LNB assembly 300, for example. Based on the determined location information, the determined time information and a received signal from a wireless source device such as the wireless source device 190, the location/time service module 326 may be operable to determine or compute location information for the wireless source device 190. The exemplary steps may proceed to the end step 804.
In various embodiments of the invention, an IP LNB assembly such as the IP LNB assembly 300 may be operational within a satellite reception assembly such as the satellite reception assembly 202. A processor 302 in the IP LNB assembly 300 may be operable to determine location information and/or time information of the IP LNB assembly 300. A location/time service module 326 in the IP LNB assembly 300 may be operable to provide services based on the determined location information and/or the determined time information of the IP LNB assembly 300. In this regard, the processor 302 may determine the location information and/or the time information of the IP LNB assembly 300 via, for example, a GNSS module 320 in the IP LNB assembly 300.
The IP LNB assembly 300 may be operable to communicate the determined location information and/or the determined time information to a wireless communication device such as the wireless communication device 180 via, for example, a wireless interface module 314. In this regard, the wireless communication device 180 may be communicatively coupled to the IP LNB assembly 300. In such instances, the wireless communication device 180 may determine location information of the wireless communication device 180, based on the location information and the time information communicated from the IP LNB assembly 300 and on other location information and corresponding other time information communicated from one or more other IP LNB assemblies 413, 423. In this regard, the wireless communication device 180 may also be communicatively coupled to the one or more other IP LNB assemblies 413, 423. The IP LNB assembly 300 may be operable to receive the location information of the wireless communication device 180 from the wireless communication device 180. The received location information of the wireless communication device 180 may then be stored in a memory 304 in the IP LNB assembly 300, for example.
The location/time service module 326 may be operable to perform digital rights management (DRM) and/or conditional access (CA) for content delivery based on the determined location information of the IP LNB assembly 300. The determined time information of the IP LNB assembly 300 may be communicated, by the IP LNB assembly 300, to one or more other IP LNB assemblies such as the IP LNB assemblies 103b, 103c in a region such as the region 170 for accurate timing recovery for the region 170. Based on the determined location information of the IP LNB assembly 300 along with other location information associated with other IP LNB assemblies 103b, 103c in the region. 170, a location map or grid 182 may be generated by the IP LNB assembly 300 for the region 170.
Based on the determined location information of the IP LNB assembly 300, relocation or move of the satellite reception assembly 602 and/or an associated gateway 605 may be detected by the location/time service module 326. In instances when an unauthorized relocation of, for example, the gateway 605 has been detected, the location/time service module 326 may communicate or report the unauthorized relocation of the gateway 605 to a satellite service provider such as the satellite service provider 120, for example. The satellite service provider 120 may then issue a warning message and/or may terminate all or partial programming services, for example.
The location/time service module 326 in the IP LNB assembly 300 may be operable to determine location information of a wireless source device such as the wireless source device 190, based on the determined location information and the determined time information of the IP LNB assembly 300 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 713, 723. In this regard, the plurality of other IP LNB assemblies 713, 723 may be communicatively coupled to the IP LNB assembly 300. The time information and each of the other time information may be determined based on receiving a corresponding signal from the wireless source device 190. The location/time service module 326 may determine the location information of the wireless source device 190 locally and/or remotely via a location server such as the location server 192, for example.
The determined location information of the wireless source device 190 along with other characteristics of the wireless source device 190 may be stored and maintained in a database 332 in the IP LNB assembly 300, for example. The database 332 may also store and maintain other location information and other characteristics information associated with a plurality of other wireless source devices, for example. In this regard, the database 332 may be made available to other devices and/or other databases for various purposes. For example, the database 332 may be utilized by a third party, in real-time or at some later time, to verify a position or location of a particular wireless source device. This may be useful for secure transactions, user identification, conditional access, estimating traffic and its flow, delivering precise and timely location-based information and services, and/or other types of transactions, for example.
