  1. Media Independent Coexistencefor White Space in TV Bands Authors: Date: 2009-03-09 Zuniga/Kwak, InterDigital

  2. 802.21: Media Independent (MI) Services • 802.21: Media Independent Services • 802.21a: Security for MI services • 802.21b: Extensions for MI downlink only technologies • 802.21c(?): MI emergency services • 802.21d(?): MI power management for multi-RAT devices • 802.21 is not just for handover anymore! • 802.21 does MI information sharing for coordination of services across RAT boundaries. • 802.21 architecture and defined interfaces are ideal for whitespace coexistence coordination and spectrum management. • Between incumbents and unlicensed users (access to FCC dbase) • Among unlicensed users: RAT, location, frequency, time info coordination • Between 802 users and non-802 users: new interfaces may be added Zuniga/Kwak, InterDigital

  3. Getting momentum! • Fixed Mobile Convergence Alliance (FMCA) 802.21 Work Item being promoted to Program level • FMCA and IEEE 802.21 starting joint interoperability effort with strong support from several Vendors and Operators • Media Independent Handover demonstrations shown at Mobile World Congress (MWC) in Barcelona, last February • IEEE 802 Tutorial describing White Space opportunities and challenges to be presented on Tue 10, 18:30 to 21:00 hrs Zuniga/Kwak, InterDigital

  4. Media specific Interfaces for Handover • MIH Protocol (MAC independent messages) defined in 802.21 • Container for MIH messages for 802.11 defined in 802.11u • Container for MIH messages for 802.16 defined in 802.16g • Working with 3GPP-SAE for 3GPP specific changes • Transport for MIH Protocol defined in IETF (MIPSHOP) Media specific changes closely follow base protocol Zuniga/Kwak, InterDigital

  5. Media specific Interfaces for Coexistence 802.21 MIC (Media Independent Coexistence) Measurements, Triggers, Network Information 802.22x for 802.22 • MIC Protocol (MAC independent messages) defined in new 802.21x • Container for MIC messages for 802.11 defined in 802.11u • Container for MIC messages for 802.16 defined in 802.16g • Container for MIC messages for 802.22 to be defined in 802.22x • Containers for MIC messages for other non-802 users possible • Transport for MIC Protocol to be defined in IETF (MIPSHOP) Media specific changes closely follow coexistence protocol defined in new coexistence coord standard Zuniga/Kwak, InterDigital

  6. MIH Users (Handover Policy, L3 or higher mobility protocol, etc.) MIH SAP Media Independent Handover Function (MIHF) (1) MIH Event Service (2) MIH Command Service (3) MIH Information Service Remote MIHF Link SAP Link Layer (e.g., 802.3, 802.11, 802.16, 3GPP) L3 transport MIH LINK SAP MIH NET SAP MIH NET SAP L2 transport IEEE 802.21: reference model for MIH • One Media Independent Handover Function (MIHF) with 3 SAPs: • MIH SAP (media independent) • MIH Link SAP (media dependent) • MIH Net SAP (for remote transport) • MIHF provides three services Zuniga/Kwak, InterDigital

  7. MIC Users (Coexistence Policy, L3 or higher mobility protocol, etc.) MIC SAP Link SAP Link Layer (e.g., 802.3, 802.11, 802.16, 3GPP) MIC LINK SAP IEEE 802.21: reference model for Coexistence • One Media Independent Coexistence Function (MICF) with 3 SAPs: • MIC SAP (media independent) • MIC Link SAP (media dependent) • MIC Net SAP (for remote transport) • MICF provides three services Remote MICF (Spectrum Manager) Media Independent Coexistence Function (MICF) MIC Event Service (for environment sensing messages) (2) MIC Command Service (for User changes/dbase queries) (3) MIC Information Service (for push/pull dbase access) L3 transport MIC NET SAP MIC NET SAP L2 transport Zuniga/Kwak, InterDigital

  10. 802.21 Ideal for Media Independent Coexistence Work Has established relationships with 802.11 & 802.16 Has established relationship with IETF for higher layer and internet transport issues While SCC41/1900.4 may be ideal approach for cell/3G systems, 802.21 is best suited to serve unlicensed technology users 802.21 does not impose general architecture 802.21 does not depend on network or terminal "manager" 802.21 approach is based on media-specific messaging for specific purposes 802.21 effectively coordinates information sharing between RATs 802.21 media independent server can facilitate access to FCC dbase and can "register" unlicensed users by location for coexistence purposes 802.21 media independent server ideal for coordinating quiet periods across RATs for sensing March 2009 10 Zuniga/Kwak, InterDigital

  11. Motion Request for EC approval to form a Study Group in 802.21 for Media Independent Coexistence for TV Band Devices (TVBD) Yes: ______ No: ______ Abstain: ______ March 2009 11 Zuniga/Kwak, InterDigital
