In a first aspect, a cell reselection method is performed by a user equipment in a mobile communication system. The cell reselection method includes: receiving, from a network, slice frequency information indicating a plurality of frequencies and a network slice group supported by each of the plurality of frequencies; and when a predetermined frequency not supporting a predetermined network slice group, of which an AS layer is notified by a NAS layer of a user equipment, is present in the slice frequency information, performing control in which a cell belonging to the predetermined frequency is less likely to be selected as a serving cell than a cell belonging to a frequency supporting the predetermined network slice group.

In an aspect, a communication method is performed in a user equipment in an RRC idle state or an RRC inactive state. The communication method includes: specifying, as a candidate cell for cell reselection, a cell belonging to a frequency supporting a selected network slice group selected in accordance with a priority provided by a NAS layer; and determining whether the candidate cell supports the selected network slice group. The determining includes: receiving a system information block from a serving cell of a user equipment for each of a plurality of network slice groups, the system information block including information indicating an identifier of the network slice group and a cell identifier of a cell that does not support the network slice group; and determining whether the candidate cell supports the selected network slice group, based on the information.

A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a private network traffic optimization service. The service may be implemented in a private network. The service may include analyzing context information pertaining to a remote core network relative to a private network in which some users may not be authorized to use a core network of the private network. The service may detect when the remote core network may be unreachable based on the analysis. The service may include analyzing context information pertaining to the core network of the private network. The service may disable routing of traffic associated with the users and enable use of the core network based on a roaming configuration, a roaming core network, and an excess capacity of the core network.

Systems and methods for implementing virtualized functions in control and data planes for a communications network are described herein. A method for managing a User Equipment (UE) attach request includes instantiating a Global Connection and Mobility Management (G-CMM) function configured to operate across a plurality of network slices in the communications network, determining an appropriate network slice from the plurality of network slices with the G-CMM function, and attaching the UE to the appropriate network slice.

A front-haul controller for a network coupling a BBU and an RRH that exchanges RF analog signals with a supported UE. The network comprises a plurality of nodes coupled by variable bit-rate network communications links. The BBU exchanges packets of frequency-domain samples with the RRH along the network. The front-haul controller monitors information about wireless spectrum occupancy at the RRH and at least one spectrum occupancy threshold and varies a bit-rate of the network link in accordance therewith. The front-haul controller can proactively adjust the bit-rate and/or the threshold during periods associated with at least one event that may impact the spectrum occupancy. The network link can be a FlexE, SONET, DWDM, LAG and/or ECMP link.

A distributed radio frequency communication system facilitates communication between wireless terminals and a core network. The system includes a group of remote radio units (RRUs). Each RRU of the group of RRUs is coupled to an antenna to communicate with at least some of the mobile terminals and includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) and communicate over a fronthaul link. The system also includes a baseband unit (BBU) coupled to the core network and the fronthaul link, and communicably coupled to the group of RRUs over the fronthaul link. The BBU includes electronic circuitry to assign one or more RRUs, selected from the group of RRUs, to a cluster of RRUs based on one or more parameters, and to perform at least a second-level protocol of the RAN.

Disclosed herein are systems and method for providing quality of service to data streams transmitted via a single protocol stream. A scheduler of a sender can receive profiles corresponding to streams of data generated by an application of the sender. The scheduler can receive, from a receiver receiving the streams of data, congestion information of some the streams of data. The scheduler can determine, according to the congestion information and the profiles, a priority of a first stream with respect to a second stream of the streams of data, for a single protocol stream. An assembler of the sender can generate a plurality of packets of the single protocol stream using first packets of the first stream and second packets of the second stream in accordance with the priority. The sender can transmit to the receiver, the single protocol stream comprising the plurality of packets.

The Distributed Software Defined Network (dSDN) disclosed herein is an end-to-end architecture that enables secure and flexible programmability across a network with full lifecycle management of services and infrastructure applications (fxDeviceApp). The dSDN also harmonizes application deployment across the network independent of the hardware vendor. As a result, the dSDN simplifies the network deployment lifecycle from concept to design to implementation to decommissioning.
