Embodiment Construction

[0031] Software-defined networking (SDN) and network function virtualization (NFV) have been used to enable network slicing in the physical core network. Network slicing involves allocating resources, such as computing, storage, and connectivity resources, to create otherwise isolated virtual networks. From the perspective of the network entities inside the slice, the slice is a distinct and independent network. The traffic carried on the first slice is invisible to the second slice because of any processing requirements within the first slice. In addition to isolating networks from each other, slicing allows each slice to be created with a different network configuration. Thus, the first slice can be created as a network function that can respond with very low latency, while the second slice can be created as a network function with very high throughput. These two slices can have different characteristics, allowing different slices to be created to serve the needs of specif...

Abstract

A method and system of allocating resources in a Radio Access Network that includes associating each of a plurality of services with a slice that is allocated a unique set of network resources and transmitting information in the Radio Access Network for at least one of the services using the slice associated with the at least one service.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Patent Application Serial No. 62 / 264,629, filed December 8, 2015, and U.S. Patent Application Serial No. 15 / 356,124, filed November 18, 2016, which The contents of both are incorporated into this application by reference. technical field [0003] The present invention relates to slicing of wireless access networks and creation of end-to-end network slices in wireless networks. Background technique [0004] When designing a mobile network, such an architecture has emerged: the network can be divided into a core network (CoreNetwork, CN) and a radio access network (Radio Access Network, RAN). The RAN provides wireless communication channels to User Equipment (UE), while the CN usually consists of nodes and functions utilizing fixed links. In the RAN, fronthaul and backhaul connections often rely on wired connections, although there are some wireless conne...
