Abstract
Various embodiments comprise systems, methods, and apparatus for allocating resources in a 5G network comprising Citizens Broadband Radio Service Device (CBSD) nodes configured for communicating via granted spectrum with customer premises equipment (CPE) supporting wireless access points (WAPs) and the like, wherein an initial small bandwidth part (BWP) is assigned to each CPE, a BWP update process provides to a policy control function a list of devices/capabilities consuming CPE bandwidth so that the PCF may calculate a new bandwidth requirement for the CPE, the new requirement being used by the CPE to generate a CPE UE capability information message for the CBSD node, the CBSD node assigning an appropriately sized BWP for the CPE.
Claims22
A method for allocating resources in a 5G network comprising Citizens Broadband Radio Service Device (CBSD) nodes configured for communicating via granted spectrum with customer premises equipment (CPE) and user equipment (UE) to provide network services thereto, the method comprising:
- at a policy control function (PCF) of a core network serving a CBSD node having at least one CPE connecting thereto and assigned a respective low resource bandwidth part (BWP), receiving from the CBSD node a list of CPE connected devices supported by the CBSD node;
- at the PCF, calculating for each CPE a bandwidth requirement sufficient to support respective CPE connected devices, and transmitting the calculated CPE bandwidth requirements toward the CBSD for use by the CPE;
- each CPE bandwidth requirement being configured to cause a respective CPE to determine a UE capability information sufficient to support the CPE bandwidth requirement, the UE capability information enabling the CBSD to assign a BWP to the CPE sufficient to support the determined UE capability information.
A system, comprising:
- a core network configured to support a 5G network comprising a plurality of Citizens Broadband Radio Service Device (CBSD) nodes configured for communicating via granted spectrum with customer premises equipment (CPE) and user equipment (UE) to provide network services thereto;
- the core network comprising a policy control function (PCF) configured to receive from each CBSD node a respective list of CPE connected devices supported by the CBSD node, the PCF responsively calculating for each CPE a respective bandwidth requirement sufficient to support respective CPE connected devices, and transmitting the calculated CPE bandwidth requirement toward the respective CBSD for use by the respective CPE;
- each CPE bandwidth requirement being configured to cause a respective CPE to determine respective connected UE capability information sufficient to support the CPE bandwidth requirement, the UE capability information enabling the CBSD to assign a BWP to the CPE sufficient to support respective connected UE.
