Configuring Service PICs and Session PICs Overview

You must configure at least one service PIC and one session PIC under a TDF gateway. The service PIC provides subscriber-aware services, such as the policy and charging enforcement function (PCEF), application detection and control, and HTTP header enrichment. The session PIC supports access subscriber sessions, policy and charging rules function (PCRF) sessions, and PCEF library installation from the PCRF.

You can configure service PICs and session PICs on MS-MPCs, and you can configure them either as a member of a redundant group by using an aggregated multiservices (AMS) interface or as a standalone service PIC or session PIC.

To configure service and session PICs:

  1. Configure the TDF gateway.

    See Configuring a TDF Gateway.

  2. If you want any of the service or session PICs to be members of redundant groups, configure an aggregated multiservices (AMS) interface for each group.

    See Configuring Aggregated Multiservices Interfaces.

  3. If you want any of the service or session PICs not to be members of redundant groups, configure a services interface.

    See Configuring a Services Interface for a Session PIC or Service PIC.

  4. Install predefined groups that are needed for configuration of the service PICs and session PICs.

    See Making Predefined Groups Available for Session PIC and Service PIC Configuration.

  5. Configure each service PIC.

    See Configuring Service PICs.

  6. Configure each session PIC.

    See Configuring Session PICs.
