Embodiment 1

[0032] figure 1 It is the SDWN-based network slice map of the present invention, figure 2 It is a schematic diagram of the resource mapping device based on SDWN of the present invention. As shown in the figure, this embodiment provides a resource mapping device based on SDWN, which is used to realize the effective allocation of wireless resources and computing resources in SDWN, including at least information collection module, resource virtualization module, sliced ​​network management module and SDN control module.

[0033] The information collection module is used to collect statistics on the number of users, location information, and business requirements, and to collect information such as resource usage, network load information, channels, and network topology. These information are used for scheduling and allocation of network resources and network virtualization. Provide evidence;

[0034] The resource virtualization module divides and reorganizes physical entity no...

Embodiment 2

[0044] image 3 It is a flow chart of the SDWN-based resource mapping method of the present invention. This embodiment provides a SDWN-based resource mapping method, including the following operations:

[0045]The information collection module makes statistics on user demand information and network resource information. The user information includes user location information, channel status, and service type, and network resources include network wireless resources and network computing resources.

[0046] Then, based on the information collected from the module, a problem model is established:

[0047] M A X x , y , μ ω Σ I , K , J x k i...

Embodiment 3

[0053] Figure 4 It is an important design goal of the resource mapping device based on SDWN, and it is also the goal pursued by the development of wireless network technology to effectively manage network resources and maximize the utilization of network resources. Effective allocation of wireless resources directly affects network service quality and user experience quality, so resource management plays a vital role in the entire network. The resource management process in a virtualized software-defined wireless network is as follows: image 3 shown.

[0054] First, the user will request to build a virtual network according to business needs, and then map and schedule the resources in the resource database through the mapping algorithm, and then form a specific virtual network according to the allocated resources and network topology, that is, a sliced ​​network, and finally Users access the slice network for data transmission. After the service transmission is over, the ...

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to an SDWN-based resource mapping device and method. Background technique [0002] In recent years, researchers have conducted research on the key technologies and application scenarios of SDN (Software Defined Network), and proposed SDN system architectures and solutions for their different needs. [0003] Ericsson 5G experts pointed out that the network architecture of traditional cellular networks, with dedicated support and IT systems, can predict traffic and traffic growth, and is very suitable for single-service user networks; however, it is difficult for operators to expand telecom networks using this vertical architecture, It is also difficult to adapt to changing user needs and meet the demands of new types of use cases. Therefore, in future 5G systems, networks will be further abstracted into network slices, where connectivity services are defined by functions ...
