Overview IEEE Std ™-2009 IEEE Standard for Local and metropolitan area networks - Part 21: Media Independent Handover Services Key Features Three services: Event Service, Command Service, and Information Service Defines a new functional entity called MIHF (MIH Function) Facilitates Multi-Radio network discovery and selection Provides abstracted services to higher layers. Communicates with the lower layers of the mobility- management protocol stack through technology-specific interfaces. MIH peer communication is performed through MIH Protocol

MIH Event Service State Change Predictive Target Link MIH Information Service Available Networks Neighbor Maps Network Services MIH Command Service Link Connectivity Control Client Initiated Network Initiated Vertical Handovers provides ND&S mechanisms across IEEE 802 and 3G(+) networks IEEE MIH Key Features (2)

PoA:L2 Point of Attachment (AP/BS) PoS: Point of Service MN: Mobile Node MIH: Media Independent Handover MIH Communication Model

MIH Event Service Enables the higher layers (L3 or above) to capture the radio link status in a standard manner Mapping media specific link layer events to Media Independent Events Link layer events From specific link layers to MIHF MIH events From MIHF to higher layers

Remote Events MIH events between different MIH entities Event lists (MIH) Link_Detected.indication (MIH) Link_Up.indication (MIH) Link_Down.indication (MIH) Link_Parameters_Report.indication (MIH) Link_Going_Down.indication (MIH) Link_Handover_Imminent.indication (MIH) Link_Handover_Complete.indication (MIH) Link_PDU_Transmit_Status.indication MIH Event Service (2)

MIH Event Service (3) MIH Remote Event Service Flow

Enables the higher layers to control the link connectivity Remote communication among peer MIHF entities Link commands From MIH to link layers MIH commands From upper layer to MIH MIH Command Service

Command lists MIH_Capability_Discover MIH_Register/MIH_Deregister MIH_Event_Subscribe/MIH_Event_Unsubscribe MIH_Link_Actions MIH_Link_Get_Parameters MIH_Net_HO_Candidate_Query, MIH_MN_HO_Candidate_Query MIH_N2N_HO_Query_Resources MIH_Net_HO_Commit, MIH_MN_HO_Commit MIH_MN_HO_Complete, MIH_N2N_HO_Complete MIH_Get_Information MIH_Push_Information MIH Command Service (2)

MIH Command Service (3) MIH Remote Command Service Flow

Provides a framework and corresponding mechanisms to discover and obtain surrounding heterogeneous network information Information Elements (IEs) General overview of network Location of PoAs, IP version, Operator Link layer parameters Channel, frequency, PHY types, data rates, Supported higher layer services or applications at the access network MIP, VPN, SIP, etc. MIH Information Service

Two types of information transfer Pull Mode: GET-RESPONSE Push Mode: One way INDICATION Push Model Information can be pushed to MN by the operator MIH Registration is mandatory for use with this push model MIH_Push_Information MIH Information Service (2)
