Abstract
A system for media independent handover using a session identifier in which a session identifier is used for identifying a media independent handover registration session across different MIH transport instances between a pair of communicating MIHFs. A point of service maintains a single registration state for a mobile node across the multiple transport instances. A session identifier is assigned by a point of service at the time of initial registration, and is valid only during the lifetime of the registration. A registration state includes local handles to transport instances that are used when sending and receiving media independent handover messages related to the registration.
Claims17
The method of media independent handover using a session identifier, comprising the steps of:
- a point of service maintaining a single registration state for a mobile node across multiple transport instances, where the transport instances are visible to the point of service;
- and
- defining a session identifier that is assigned by a point of service at the time of initial registration, said session ID being valid only during the lifetime of the registration.
The method of media independent handover using a session identifier, comprising the steps of:
- a point of service maintaining a single registration state for a mobile node across multiple transport instance, where the transport instances are not visible to the point of service;
- defining a session identifier that is assigned by a non-point of service media independent handover, at the time of initial registration, said session ID being global unique to support multi-hop sessions.
