Description
Technical field
The present invention relates to network communication field, the system of more particularly to a kind of multiple terminals collaboration based on strategy and side
Method.
Background technology
With developing rapidly for the communication technology, the phenomenon of the overlapping covering of multiple network is more and more universal, in multiple nets
Terminal under network covering potentially can access and use simultaneously multiple networks.But it is the reason for being due to technology or policy, a certain
Terminal is typically a certain network of use of selectivity or hardness, virtually causes the waste of Internet resources.At the same time, with intelligence
The popularization of energy terminal, increasing intelligent terminal appears in network edge or user periphery.Forum is wirelessly studied according to the world
（WWRF）Prediction, " by 2017, the whole world will appear from 7,000,000,000,000 radio terminal services in 7,000,000,000 populations ".But intelligent terminal（Especially
It is portable mobile terminal）Limited ability, by single terminal end it is difficult to provide the user high-quality business experience, will appear from by many
Terminal cooperates with the scene for providing the user information service.Therefore, following network would is that the network of a fusion collaboration, terminal
High-quality service may be provided the user across the communication service network of isomery.And information service high bandwidth, content-form are more
Memberization, business provide intelligentized development, and the terminal and the control of its network to various networks propose higher requirement.Therefore,
Study multiple terminals synergistic application and its correlation technique be significant, new selection is not only brought to business presentation mode,
Laid the foundation for the synergistic application under following mobile environment.
Based on the management method of strategy realized by strategy to being managed the distributed of system, automation and dynamic
Adaptive management, is increasingly taken seriously in the academic research and application for be related to dynamic regulation.At present, IETF, electricity
Believe the standardization bodies such as management forum (TeleManagement Forum, TMF), London Royal Academy, the distribution in Europe
Formula management role group（Distributed Management Task Force, DMTF）All accumulated Deng research tissue and many universities
The research of the management method based on strategy has been carried out in pole, and has been achieved for fruitful achievement.Particularly ietf definition
Policy Core Information Model（Policy Core Information Model, PCIM）And its extension（PCIMe）（Referring to IETF
RFC3460）, policy based network management（Policy Based Network Management,PBNM）Framework（Referring to
IETF RFC3318）Normalized base is provided for policy management system.But there is presently no tactical management is used for into multiple terminals
The correlative study of cooperative system.Adaptively adjusted according to terminal capability, network environment and business demand thus, it is necessary to study one kind
The method and corresponding policy information model of whole terminal collaborative strategy, so as to easily and efficiently improve user QoE, are finally carried
The utilization rate of high Internet resources.
The content of the invention
In order to solve the problem of unit/terminal in the prior art can not provide the user high bandwidth, the business of high qos requirement, this
Invention provides a kind of multiple terminals cooperative system and method.
