More Information
Summary:A network device may receive a context creation request based on a protocol data unit (PDU) session establishment request for establishing a PDU session with a user device, and may generate a policy context request based on receiving the context creation request. The network device may provide the policy context request to a policy control function (PCF), and may receive, from the PCF and based on the policy context request, policy rules for the PDU session. The network device may receive, from the PCF, a terminate PDU session notification indicating that a binding support function (BSF) is unreachable, and may generate, based on the terminate PDU session notification, a PDU session release command that includes a cause code indicating an issue with the BSF and an instruction to not reinitiate the PDU session. The network device may cause the PDU session release command to be provided to the user device.
