  1. Media Independent Coexistence Authors: Date: 2009-03-11 Zuniga/Kwak, InterDigital

  2. 802.21: Media Independent Handover Services &? • 802.21: MI Handover services • 802.21a: Security for MI services • 802.21b: Extensions for MI downlink only technologies • 802.21.1(proposed): MI Emergency services • 802.21x(proposed): MI power management for multi-RAT devices • 802.21 does MI information sharing for coordination of services across RAT boundaries. • 802.21 framework and defined interfaces are suitable 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. Existing: Media specific Interfaces for Handover 802.16g/h for 802.16 • MIH Protocol (MAC independent messages) defined in 802.21 • Container for MIH messages for 802.11 defined in 802.11u • Container and primitives for MIH messages for 802.16 defined in 802.16g/h • 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

  4. Proposed: Media specific Interfaces for Coexistence 802.21 MIC (Media Independent Coexistence) Measurements, Triggers, Network Information 802.22x for 802.22 802.16g/h for 802.16 • MIC Protocol (MAC independent messages) defined in new 802.21x • Container for MIC messages for 802.11 defined in 802.11u • Container and primitives for MIH messages for 802.16 defined in 802.16g/h • Container for MIC messages for 802.22 to be defined in 802.22x • Containers for MIC messages for 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

  5. 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 Existing: 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

  6. 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 Proposed: 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

  9. 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.

  10. Strawpolls Should the ECSG recommend that 802.21 request EC approval to form a Study Group for Media Independent Coexistence of TVBD Devices? Yes: 17 No: 2 Abstain: 16 Should the ECSG recommend that the 802.21 Media Independent Coexistence Group form liaisons with other standards organizations? Yes: 14 No: 1 Abstain: 18 March 2009 10 Zuniga/Kwak, InterDigital
