How it Works

This section describes how this feature works.

  • Message Prioritization Handling Framework

    • Diameter Configuration—Use Message Handling Rules parameters (Diameter Client, Protocol, Command Code, Request Type, Priority, Per Instance TPS, and Discard Behavior) to identify and prioritize the diameter messages.

    • PCF Configuration—Use Message Handling Rules parameters (Request Type, Priority, Per Instance TPS, and Discard Behavior) to identify and prioritize the SBI messages.

  • Inbound WPS Rx Message Prioritization—Use the Rx Message Prioritization parameters to mark the WPS specific MPS-Identifier and Reservation Priority. Rx message should be prioritized based on the MPS-Identifier and Reservation-Priority AVPs received in the request message.

  • Inbound WPS SBI Message Prioritization—Based on the SBI Message Priority value in the incoming message, a user specified priority (Inbound SBI-Message-Priority prioritization table in PCF configuration) is assigned. SBI messages with higher priority are considered for processing earlier than the messages with lower priority.

Note

Currently, the priority queue and rate limiting for REST and Diameter messages are independent of each other.
