3. IEEE 802.19.1 Architecture Coexistence Enabler – Request and obtain information, required for coexistence, from TVBD network or device – Translate reconfiguration requests/commands to TVBD- specific Coexistence Manager – Discovery of other CMs – Decision Making – Support exchange of information –.. Coexistence Discovery and Information Server – Support Discovery of CMs – Collect, aggregate information CHECK NEXT SLIDE FOR MAPPING TO.21 ARCHITECTURE

4. IEEE 802.19.1 Architecture mapping to IEEE 802.21 Coexistence Discovery and Information Server Coexistence Manager Coexistence Enabler Another Coexistence Manager TVBD Network or Device TVWS Database Operator Management Entity MIHF (Extended) MIH Users MIIS MIH_SAP MIH_LINK_SAP MIH_NET_SAP Interface A=MIH_LINK_SAP Interface B1=MIH_SAP Interface B3=MIH_SAP+MIH_NET_SAP Interface C and D=MIH_SAP+MIH_NET_SAP Other TVBD device or network (supporting the MIHF)

5. Set of System Requirements Requirements in red are not in scope of.21 (IMHO), requirements in green are in scope while in blue I am in doubts. R1: 802.19.1 system shall enable discovery for 802.19.1 compliant TVBD networks and devices R2: 802.19.1 system shall be able to obtain and update information required for TVWS coexistence R3: 802.19.1 system shall have means to exchange obtained information R4: 802.19.1 system shall be able to provide reconfiguration requests and/or commands as well as corresponding control information to 802.19.1 compliant TVBD networks and devices to implement TVWS coexistence decisions R5: 802.19.1 system shall analyze obtained information R6: 802.19.1 system shall be capable of making TVWS coexistence decisions R7: 802.19.1 system shall support different topologies of decision making for TVWS coexistence (e.g. centralized, distributed and autonomous) R8: 802.19.1 system shall support appropriate security mechanisms. This shall include user/device authentication, integrity and confidentiality of open exchanges, and data privacy and policy correctness attestation and enforcement R9: 802.19.1 system shall utilize a set of mechanisms to achieve coexistence of TVBD networks and devices

6. R2: 802.19.1 system shall be able to obtain and update information required for TVWS coexistence At least two sources of information: – TVWS database – Other TVBD network/devices.21 MIIS can be used as foundation – Same concept, information in a geographical area – Transport protocol already defined – There are already some IEs with frequency information Required changes – Push information into the MIIS – Information taken from other TVBDs? Events, local MIIS, MIIS proxy mode? – IEs for MIIS, specifically for TVWS and potentially some extra IEs for policies etc..

7. R3: 802.19.1 system shall have means to exchange obtained information.21 already has remote communication mechanisms, over L2 and L3 – MIH protocol can be used – RFC5677 No required change

8. R4: 802.19.1 system shall be able to provide reconfiguration requests and/or commands as well as corresponding control information to 802.19.1 compliant TVBD networks and devices to implement TVWS coexistence decisions Commands for radio configuration – Remote and local Changes – Introduce Interface notion in the standard – Introduce commands for radio configuration Nothing fancy, just freq and power at beginning – Make sure the.21 architecture/ref model allows the required communication paths

9. Blue Ones R1: 802.19.1 system shall enable discovery for 802.19.1 compliant TVBD networks and devices: – Discovery of Coexistence Services using.21: Extensions to RFC 5678 (DHCP Options for.21) and RFC 5679 (Locating.21 services through DNS) – Discovery of other.19.1 compliant devices: Thing to explore, maybe a Media Independent Beaconing system R7: 802.19.1 system shall support different topologies of decision making for TVWS coexistence (e.g. centralized, distributed and autonomous) – A.21 based approach is compatible with this requirement since we do not force any specific topology R8: 802.19.1 system shall support appropriate security mechanisms. This shall include: – user/device authentication: IMHO 802.21a covers this – integrity and confidentiality of open exchanges: IMHO 802.21a covers this – data privacy: IMHO 802.21a covers this – policy correctness attestation and enforcement: Not covered in IEEE 802.21
