Abstract
This disclosure describes techniques that enable a telecommunication network to share available bandwidth within a cell of a base station node between different air-interface technologies, such as Long-Term Evolution (LTE) and 5G-New Radio (5G-NR). The available bandwidth may be shared based on bandwidth allocation rules and an analysis of network traffic, in real-time. Moreover, a Spectrum Sharing Optimization (SSO) system is described that can generate optimization data for delivery to a base station node. The optimization data may include computer-executable instructions that dynamically make use of time-division (i.e. configuring MBSFN subframes) and frequency-division techniques (i.e. configuring BWPs) to share available bandwidth within the cell of the base station node.

A computer-implemented method, comprising:
- under control of one or more processors:
- retrieving, from a data store, historical network traffic data associated with a base station node;
- generating a network-congestion model for the base station node, based at least in part on the historical network traffic data;
- monitoring network traffic data at the base station node, the base station node including at least one cell that is configured for 5G-NR communication transmissions via a 5G-New Radio (5G-NR) spectrum;
- analyzing the network traffic data with data-points of the network-congestion model to determine an LTE bandwidth requirement and a bandwidth part (BWP) for 5G-NR communication transmissions within one cell of the base station node;
- identifying a select number of subframes of a plurality of subframes associated with the one cell for configuration as Multicast Broadcast Single Frequency Network (MBSFN) subframes for LTE communication transmissions, based at least in part on the LTE bandwidth requirement;
- and
- generating optimization data for transmission to the base station node, the optimization data including computer-executable instructions that configure the select number of subframes as the MBSFN subframes and further configure the BWP within the one cell of the base station node.
One or more non-transitory computer-readable media storing computer-executable instructions that, when executed on one or more processors, cause the one or more processors to perform acts comprising:
- retrieving, from a data store, historical network traffic data associated with a base station node;
- generating a network-congestion model for the base station node, based at least in part on the historical network traffic data;
- analyzing network traffic data at the base station node operating within a telecommunication network relative to data-points of the network-congestion model to determine an LTE bandwidth requirement and a bandwidth part (BWP) for 5G-NR communication transmissions, the base station node including at least one cell that is configured for communications via a first spectrum;
- identifying a select number of subframes of a plurality of subframes associated with the one cell for configuration as Multicast Broadcast Single Frequency Network (MBSFN) subframes for communication transmissions via a second spectrum, based at least in part on analysis of the network traffic data;
- identifying a plurality of client devices configured to operate within a 5G-NR spectrum, the 5G-NR spectrum corresponding to one of the first spectrum or the second spectrum;
- and
- generating optimization data for transmission to the base station node, the optimization data including computer-executable instructions that configure the select number of subframes as the MBSFN subframes and further configure the BWP within the one cell of the base station node.
A system comprising:
- one or more processors;
- memory coupled to the one or more processors, the memory including one or more modules that are executable by the one or more processors to:
- retrieve, from a data store, historical network traffic data associated with a base station node;
- generate a network-congestion model for the base station node, based at least in part on the historical network traffic data;
- monitor network traffic data at the base station node operating within a telecommunication network, the base station node including at least one cell that is configured for communications via a first spectrum;
- correlate the network traffic data with data-points of the network-congestion model to determine an LTE bandwidth requirement and a bandwidth part (BWP) for 5G-NR communication transmissions within the at least one cell of the base station node;
- identify a select number of subframes of a plurality of subframes associated with the one cell for configuration as Multicast Broadcast Single Frequency Network (MBSFN) subframes for communication transmissions via a second spectrum, based at least in part on a correlation of the network traffic data with data points of the network-congestion model;
- and
- generate optimization data for transmission to the base station node that includes computer-executable instructions to configure the select number of subframes as the MBSFN subframes and further configure the BWP within the one cell of the base station node.
