2 Binding Support Function Architecture

This section provides information about Binding Support Function Architecture.

The BSF Management Service is an internal service used for the OCPM BSF/PCF to provide a PDU session binding functionality, which ensures that an AF request for a certain PDU Session reaches the relevant PCF holding the PDU Session information.

The service implements the Binding Support Management Service as defined in 3GPP TS 29.521 [4].

The service allows consumers to register, deregister, and discover the binding information.

Binding Support Function Management Service Architecture

BSF Management Service is designed as a micro service that can be deployed in a standalone BSF.

Note:

BSF Management Service only supports storing, removing, and querying binding information from RDBMS, and additional storage options. For example, In-memory DB, and UDSF.
