Key Features A generic and flexible MIH reference model that can apply to different technologies such as cellular and 802.X Logical view of network architecture which shows how 802.21 fits in heterogeneous networks. Introduction of generic trigger information that can be tailor-made to accommodate multiple access technologies. Comprehensive call flow scenarios including System access Handover Success and failure cases Details of SAP, triggers and MIH services Analysis of Mobile IP enhancement and its interactions with 802.21 Supports seamless service continuity Flexible for implementation and requires minimum effort of standardization work throughout the different standards groups 21-05-xxxx-00-0000

Updates since Last Revision Trigger Definition has been updated as per harmonization exercise. Normative and informative components of the proposal have been identified Remote transport mechanism is defined based on the introduction of a new ether type that introduces a new MIH protocol 21-05-xxxx-00-0000

MIH Service Description IEEE 802.21 specifies a set of services that allow seamless handovers across heterogeneous access networks. A seamless handovers can be defined as one that allows the delivery of a service on a new access interface with equal quality as the previous access interface and that it is imperceptible to an end user The service encompasses the following: Information Service (IS): The IS provides a description of available access networks and their offered capabilities. This allows the use of state machines that trigger handovers and system access towards the best possible connection for the delivery of a service. This includes System Operator, Network Identities, QoS and offered access technology amongst other. Event Service (ES): The ES provides notifications with regards to changes to both upper and lower layers associated to a particular link and surrounding access networks. Notification are generated when either the current link no longer supports service requirements or a better candidate has been found. Media Independent Handover Function (MIH): MIH provides a set of procedures that support the handover decision that uses both IS and ES to determine the best point of attachment for the delivery of a service for both initial network selection and handover. MIH considers inputs from multiple access networks when determining a handover candidate. MIH uses IS and ES information from both upper and lower layer when applying policy criteria. 21-05-xxxx-00-0000
