Problems solved by technology

On the one hand, technological development has brought diversified choices to users; on the other hand, it has also brought about inconvenient access problems caused by incompatibility of multiple standards, and discontinuous services caused by multiple network partitions.
The conventional solution is to develop various types of multi-mode terminals for the former, and solve the problem of seamless access with omnipotent terminals. The cost is the increase in terminal complexity and user costs, and it is difficult to adapt to future invisible Technological development

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The collaborative network concept of the present invention can be characterized by "one center, three environments, and polymorphic reconstruction".

[0018] "One center" means that the construction and design of the entire network is centered on the user (user), and must be based on the most convenient service for the user.

[0019] "Triple environment" refers to virtual terminal environment, heterogeneous network environment and converged business environment. Among them, the virtual terminal refers to the fact that in a multi-radio environment, it does not rely on highly intelligent multi-mode terminals to achieve ubiquitous access, but reuses multiple existing terminal devices of the user. Synthesized to form a virtual terminal with enhanced capabilities, the system can automatically select a suitable terminal device to ac...

Abstract

The invention designs a smart service system (3S) of the Internet of things based on software definition. According to the system, a user is used as a center, business is used for driving, and a software definition mode is adopted, so as to construct the smart service system oriented to an application environment of the Internet of things. The smart service system is characterized in that for ubiquitous wireless network architecture and three software definition control platforms, i.e. a software definition service control platform, a software definition network control platform and a software definition terminal control platform, individual businesses, networks and terminals are customized for users through software according to business requirements of the users. A network function virtualization technique is introduced through the software definition control platforms, so that multidimensional resources are communicated, calculated and stored for integrated optimization, resource barriers of heterogeneous networks and different industries and departments are broken through, resource sharing is realized, and a network using the user as the center is established, so as to adapt to the development requirement of the Internet of things at last.

Description

technical field [0001] The present invention designs a software-defined intelligent service system and its architecture, which are mainly applied to the fifth generation mobile communication system (5G), Internet of Things technology and application, and belong to the technical field of Internet of Things. Background technique [0002] With the rapid development of broadband wireless technology, new access technologies are constantly emerging, and correspondingly new networks and new terminals are also constantly emerging. The communication system presents the characteristics of heterogeneity, diversity and ubiquity. the challenges of a multi-radio environment. On the one hand, technological development has brought diversified choices to users; on the other hand, it has also brought about inconvenient access problems caused by incompatibility of multiple standards, and discontinuous services caused by multiple network partitions. The conventional solution is to develop vari...
