SYSTEM AND METHOD FOR REDUCING CONTROL DATA TRAFFIC IN A WHITE SPACE NETWORK

摘要

Systems and methods to reduce control data traffic between a hub radio device (e.g., a master white space device) and spoke radio devices (e.g., slave white space devices). Reduced are the number of control messages and/or the amount of data transmitted in control data messages. The hub radio device stores data regarding the spoke radio devices that register for white space access (e.g., specific spectrum access credentials) with a spectrum management server via the hub radio device. As long as conditions regarding a spoke radio device remain relatively unchanged, the stored data for the spoke radio device may be used to maintain the white space access through periodic renewal of the corresponding channel authorization with the spectrum management server.

主权项

1. A spoke radio device, comprising:
radio circuitry configured to engage in wireless communications, the wireless communications including establishing a link with a hub radio device using generic channel access credentials to support acquisition of specific channel access credentials from a spectrum management server; and a control circuit that executes logical instructions to configure the spoke radio device to:
generate and send a detailed channel list request to the hub radio device, the detailed channel list including plural data items selected from a data item to identify the spoke radio device, a data item that specifies current location of the spoke radio device, a data item to identify information regarding an owner or operator of the spoke radio device, and a data item to identify one or more operational characteristics of the spoke radio device;process a channel list response containing the spectrum channel access credentials and received in response to the detailed channel list request, including selecting an available channel specified in the channel list response for use in wireless communications; andgenerate and send a renewal request to the hub radio device to maintain valid use of the selected channel, the renewal request containing fewer data items than the detailed channel list request.
