Feature Description

The PCF is compliant with the December 2018 and June 2019 compliance version of 3GPP specification for the PCF interfaces such as N7, N25, N28, and Nnrf. The PCF processes the messages from these interfaces as per the compliance profile configured for the corresponding services.

Currently, IE encoding and decoding are supported. Only the existing features work with the June 2019 specification versions. No additional features in the June 2019 version are supported.


Note

The PCF continues to support the older versions of 3GPP specifications and the compliance profile configuration controls the same for the PCF interfaces.

Standards Compliance

The PCF is one of the control plane network functions (NFs) of the 5G core network. The PCF uses different interfaces to communicate with the other NFs or nodes, for example, the N7 interface exists between the SMF and PCF. Each of the PCF interfaces complies with a specific version of 3GPP specification.

Use the following table to determine the compliance mapping of each PCF interface and the 3GPP Standards specification versions.
