System and method for reducing control data traffic in a white space network
First Claim
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 request including plural data items selected from a data item to identify the spoke radio device, a data item to specify a 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 specific 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; and
generate 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; and
wherein the logical instructions further configure the spoke radio device to process a renewal reply received from the hub radio device, the renewal reply being;
an acknowledgment reply that does not contain channel availability data if the selected channel is still available for use by the spoke radio device, in which case the spoke radio device continues wireless communications using the selected channel;
elsea channel list response specifying new specific channel access credentials, in which case the spoke radio device makes a new channel selection.

Abstract
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.

9. A hub radio device, comprising:
-
radio circuitry configured to engage in wireless communications using specific operating parameters, the hub radio device having a coverage area in which spoke radio devices are entitled to communicate with the hub radio device using generic operating parameters; a memory; and a control circuit that executes logical instructions to configure the hub radio device to; receive a detailed channel list request from one of the spoke radio devices, the detailed channel list request including plural data items selected from a data item to identify the spoke radio device, a data item to specify a 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; send a first proxy channel list request to a spectrum management server with the data items from the detailed channel list request, obtain a base channel list response from the spectrum management server in response to the first proxy channel list request and send the base channel list response to the spoke radio device; receive a renewal request from the spoke radio device, the renewal request containing fewer data items than the detailed channel list request; and generate and send a second proxy channel list request to the spectrum management server with a location of the spoke radio device from the renewal request and data items from the detailed channel list request; and wherein the hub radio device determines whether a channel selected by the spoke radio device for wireless communications is still available for use by the spoke radio device according to channel availability specified in a renewal channel list response and sends a renewal reply to the spoke radio device, the renewal reply being; an acknowledgment reply that does not contain channel availability data if the selected channel is still available for use by the spoke radio device;
elsea channel list response specifying available channels from the renewal channel list response. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
