Multi-bearer network
A multi-bearer network is a network having the capability to carry a data packet via one of several alternative bearers. To be more precise, the term multi-bearer network should be interpreted as meaning 'multi-bearer-type network', or in other words, a network arrangement which provides multiple different bearer types for data packet delivery.
Background of multi-bearer network
An example of a suitable MBN is a concept known as Multimedia Environment for Mobiles. Additionally, the MBN supports mobility of a subscriber terminal. An example of terminal mobility is IP mobility, which is the topic of standard by the .The problem underlying the invention is how to select the optimal bearer for each data packet in varying situations in a multi-bearer network. Data packets have different quality-of-service requirements. Situations may vary because the subscriber moves or the network load changes.
