  • Patent number: 8116787
    Abstract: Coverage-based quality-of-service (QoS) in wireless networks. A premium QoS service is provided by the network to users who qualify to receive QoS signals by moving handsets into a bounded premium service geographical coverage area. A mobile handset periodically transmits handset lat-long data to the wireless network via a control channel. The network includes data that defines the bounded geographical coverage area. The wireless network receives the handset lat-long data and maps the data to coverage area data. If the handset lat-long data maps into the coverage area data, the user handset is authorized to receive and use the premium QoS signals over a 3G network; otherwise, the user falls back to default service on a 2G network. Alternatively, the network utilizes a trained neural network to process the lat-long data to qualify the handset for premium services.
