PAWS J. Caufield Internet-Draft Key Bridge Intended status: Experimental B. Patil Expires: April 26, 2012 Nokia October 24, 2011 Protocol to query a White Space Database draft-caufield-paws-protocol-for-tvws-00.txt Abstract Regulatory entities in many countries are making spectrum previously used by television stations available for secondary use as a result of the switch from analog to digital. The spectrum in such cases is still owned by the primary user to whom it is licensed. However parts of the spectrum may be unused at a given location or time and hence can be made available for secondary use. In order to use such spectrum a device has to query a database in order to obtain a list of available channels or spectrum at a given location and time. This document specifies a protocol that can be used to query a white space database by a device.

Introduction Regulatory entities in many countries are making spectrum previously used by television stations available for secondary use as a result of the switch from analog to digital. The spectrum in such cases is still owned by the primary user to whom it is licensed. However parts of the spectrum may be unused at a given location or time and hence can be made available for secondary use. In order to use such spectrum a device has to query a database in order to obtain a list of available channels or spectrum at a given location and time. This document specifies a protocol that can be used to query a white space database by a device. The problem statement, use cases and requirements for the use of white space spectrum and the associated protocol is captured in the document: [I-D.ietf-paws-problem-stmt-usecases-rqmts]. 2. Terminology and Abbreviations The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. This document relies on the terminology specified in [I-D.ietf-paws-problem-stmt-usecases-rqmts]. 3. Background Provide some background material on the PAWS protocol. 4. Problem Statement Capture the problem statement for the protocol without repeating what is stated in the PS I-D. 5. The Protocol Specify the details of the protocol itself here. 6. Query Parameters Specify in XML the parameters that need to be carried in the request/ response protocol.

IANA Considerations This document will require actions on the part of IANA to assign values for the new messages and attributes. 8. Security Considerations Protocol security and threats need to be specified here. 9. Acknowledgements List people who have helped improve this contribution. 10. References 10.1.
