Abstract
This disclosure describes techniques that enable a telecommunications network to share available bandwidth within a cell of base station node between different air-interface technologies, such as Long-Term Evolution (LTE) and 5G-New Radio (5G-NR). This disclosure further enables spectrum allocation to service segments of a base station node. A spectrum allocation controller is described that is configured to identify, within a service area of a base station node, available spectrum, and in doing so, allocate available spectrum to non-overlapping service segments.
Claims18
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:
- monitor network traffic data within a service area of a base station node that includes at least one cell;
- identify available spectrums within the service area, the available spectrums including a citizen broadband radio service spectrum (CBRS) and a licensed spectrum that corresponds to a Long-Term Evolution (LTE) spectrum;
- allocate a first spectrum of the available spectrums to an initial service segment of the service area, the initial service segment extending outward from the base station node to an initial service edge;
- allocate the CBRS to a second service segment of the service area, the second service segment extending outward from the initial service edge to a second service edge;
- generate scheduling criteria to allocate the network traffic that is transmitted within the initial service segment to the first spectrum and the network traffic that is transmitted within the second service segment to the CBRS;
- in response to a determination that a spectrum allocation of the CBRS is time expired, allocate the licensed spectrum to the second service segment of the service area, and generate additional scheduling criteria to allocate network traffic that is transmitted with the second service segment to the licensed spectrum;
- analyze the network traffic data to determine an LTE bandwidth requirement;
- identify a select number of subframes of a plurality of subframes associated with the at least one cell for configuration as Multicast Broadcast Single Frequency Network (MBSFN) subframes for LTE communication transmissions via the licensed spectrum, based at least in part on the LTE bandwidth requirement;
- and
- generate optimization data for delivery to the base station node to configure the select number of subframes as the MBSFN subframes.

A computer-implemented method, comprising:
- under control of one or more processors:
- identifying available spectrums within a service area of a base station node that includes at least one cell, the available spectrums including a citizen broadband radio service spectrum (CBRS) and a licensed spectrum that corresponds to a 5G-NR spectrum;
- allocating a first spectrum of the available spectrums to a first service segment of the service area, the first service segment extending outward from the base station node to a first service edge;
- allocating the CBRS to a second service segment of the service area, the second service segment extending outward from the first service edge to a second service edge;
- generating scheduling criteria to allocate network traffic transmitted within the first service segment to the first spectrum and network traffic transmitted within the second service segment to the CBRS;
- in response to determining that a spectrum allocation of the CBRS is time expired, allocating the licensed spectrum to the second service segment of the service area, and generating additional scheduling criteria to allocate network traffic that is transmitted with the second service segment to the licensed spectrum;
- analyzing network traffic within the second service segment to determine a 5G-New Radio (5G-NR) bandwidth requirement;
- identifying a select number of subframes of a plurality of subframes associated with the at least one cell for configuration as Multicast Broadcast Single Frequency Network (MBSFN) subframes for long-Term Evolution (LTE) communication transmissions, based at least in part on the 5G-NR bandwidth requirement;
- and
- generating optimization data for delivery to the base station node to configure the select number of subframes as the MBSFN subframes.
