TELECOMMUNICATIONS SYSTEM, AND METHOD OF TRANSPORT PROVISION FOR SERVICE TO USER IN TELECOMMUNICATIONS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide hand-over between systems to minimize impulse that a user feels, in a service under progression by optimizing an entire data rate when a location or mobility level of the user is changed just for an appropriate amount.;SOLUTION: The telecommunications system comprises a plurality of networks. At least one of the networks is a network for wireless telecommunications. Each network comprises a network controller, and the system also comprises a user controller. The user controller negotiates with the network controllers for providing transport for a service to the user. The user controller agrees contracts for transport with at least two networks, in respect to each of which the probability of providing transport is less than one.;COPYRIGHT: (C)2005,JPO&NCIPI
