Mobile Satellite TV Wireless Network Access via Location-Based Preauthorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile satellite television systems lack the ability to access wireless networks without a hard-wired connection, limiting their connectivity and functionality, especially in vehicles where mobility prevents the use of traditional telephone wires for conditional access and return path applications.
Innovation Solution
A method that generates a wireless network access signal, communicates it to a mobile receiving device, and enables its use by determining the device's location to obtain the appropriate wireless network access signal, allowing connectivity through wireless access points without the need for a hard-wired connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard-wired telephone wire connection is used for conditional access and return path applications, then reliable network access is achieved, but mobility is lost
Solution Approach 1:
The patent replaces the mechanical hard-wired telephone connection with a wireless communication system. The mobile receiving device obtains wireless network access signals through wireless transmission rather than physical wire connection, eliminating the mechanical constraint while maintaining network access capability. This substitution resolves the contradiction by providing both mobility (no wire) and reliable access (wireless signal transmission).
2Adaptability or versatility
If wireless network access is implemented without hard-wired connection, then mobility is maintained, but network access capability is limited
Solution Approach 1:
The system performs preliminary actions by determining the location of the mobile receiving device before providing wireless network access. The business controller receives location information and pre-authors the device for wireless networks in the determined location, ensuring network access capability is established in advance before the device actually needs to connect, thus maintaining both mobility and reliable access.
3Reliability
If location determination is performed to obtain appropriate wireless network access signals, then network connectivity is improved, but system complexity increases
Solution Approach 1:
The patent introduces a business controller as an intermediary between the mobile receiving device and wireless networks. The business controller receives location information from the device, determines appropriate networks, and provides authentication signals. This intermediary simplifies the overall system by centralizing the complex location-based network selection and authentication logic, reducing the complexity burden on the mobile device itself while improving connectivity.

AI summary
A mobile wireless system includes a transmitter such as a satellite that broadcasts wireless signals such as boundaries for wireless networks to a mobile receiving device. Mobile receiving device may include an antenna. A locating receiver is used to generate locating signals so that a determination may be made to the location of the mobile receiving device. Preauthorizations may be obtained to allow the mobile receiving device to communicate back to business controller to enable functions such as pay-per-view or on-demand, interactive television, gaming, and the like. The preauthorizations enable access to various wireless networks as the mobile receiving device moves.
