A method of employing an encoding scheme for media independent handover, comprising: having at least some data type carry only required information to determine the end of data without a length value.

Data type encoding for media independent handover

A terminal device includes multiple interfaces having links to various networks. When a trigger event occurs, the terminal device selects a target link to a network to transition from its current link. A candidate link selection function determines candidate links that are filtered to remove links not meeting connectivity criteria. A target link selection function is then executed to select a target link from the filtered candidate links. Thus, the target link selection function is not run for every possible link, but only those meeting the criteria.

Network selection mechanism

This document describes Toll Free IP (TIP), a business model and its enabling methods to provide no-charge-to-user ('toll-free') connectivity through IP-based access networks (e.g., public wireless hotspot networks based on IEEE 802.11), which may be operated by different network operators. With TIP, the use of networks to communicate with a toll-free IP destination will be paid by the owner of the toll-free IP destination. A toll-free IP destination can be identified in many ways, e.g., by a toll-free IP address, toll-free Internet Domain Name, a toll-free Universal Resource Identifier or Universal Resource Locator. TIP enables a user to use networks without prior service subscriptions with network or service providers and without any special terminal software or hardware for gaining permission to use a network. It allows users to use more access networks, i.e., larger 'footprints', than any individual network operator or aggregator can provide. With TIP, a service provider can provide services over IP-based access networks without the need to have business arrangements with each individual network operator or aggregator. TIP can also be used to enable other value-added services such as Prepaid IP, Collect IP, Selective Charging, and a single prepaid account across access networks of multiple operators or aggregators and even across wireless LANs (e.g., public hotspots and enterprise wireless LANs) and cellular networks.

Method and systems for toll-free internet protocol communication services

A Multi-Interface Mobility Management (MIMM) client is provided on a mobile Multi-Interface Device (MID) to support seamless network connectivity and switching of the MID. The MIMM client communicates with a MIMM Server. The MIMM Server collects information from MIMM Clients and provides information to the MIMM Clients pertaining to the network(s) to which the mobile MID has access, such as information concerning the availability of a network, the quality of network connectivity, etc. The MIMM Client is responsible for determining whether and when a handoff or roaming operation should be initiated by the mobile MID, and which network interface the mobile MID should use after the handoff/roam operation has been completed. The MIMM Client also is responsible for performing mobility-related functions that are required prior and subsequent to the handoff/roam operation. The MIMM Client uses the information received from the MIMM Server in order to make these determinations.
