Overview

The PCF provides the Policy Builder as an interface for policy management. Policies translate a Service Provider’s business rules into actionable, logical processing methods that the PCF enforces on the network.

The PCF ships with some standard base policies that serve as a starting point for customization to suit a Service Provider's specific business rules.

Adding a System

This section describes how to add a system.

After installation, use this procedure to set up your Policy Builder by using an example populated with default data. You can change anything that does not apply to your deployment.

  1. Click the Reference Data tab, and then click the Systems node to display the Systems tree.

  2. Click System... under Create Child: to open the System pane on the right side.

  3. Fill in the Name field, and provide a description of this system. Enter the rest of the parameters based on your network requirements.

    Table 3. System Parameters

    Parameter

    Description

    Name

    The name of the PCF system.

    Description

    Describes the system using which you can uniquely identify the system.

    Session Expiration Hours

    An event occurs whenever a session is updated, which in turn increments the session expiry duration.

    If no session update event occurs in the specified session expiration duration (combination of Session Expiration Hours and Session Expiration Minutes), then the session will be removed.

    Note 

    The combined value of Session Expiration Hours multiplied by 60 plus Session Expiration Minutes should not exceed 35,400 minutes.

    Default value is 8.

    Session Expiration Minutes

    An event occurs whenever a session is updated, which in turn increments the session expiry duration.

    If no session update event occurs in the specified session expiration duration (combination of Session Expiration Hours and Session Expiration Minutes), then the session will be removed.

    Note 

    The combined value of Session Expiration Hours multiplied by 60 plus Session Expiration Minutes should not exceed 35,400 minutes.

    Default value is 0.

    Timeout for Unknown Session

    Time in minutes that PCF keeps a session alive after the subscriber logs off. With this, other network entities involved in the session can let the session close gracefully.

    Default value is 0.

    Timeout For Soft Delete

    Determines the time in seconds during which a 'soft delete' session is maintained for a PCF session after session stop.

    Default value is 30.

    Session Limit Overload Protection

    This parameter is used to protect the session database from crashing. PCF does not allow session creation when a current system session count exceeds the Session Limit Overload Protection value.

    The default value is set to 0 which infinitely accepts the Diameter messages and PCF triggers alarms so that you change the value before session count goes beyond the database capacity. This value must be replaced by session capacity that is calculated for each deployment.

    Default value is 0.

    Note 

    Session Limit Overload Protection value must be changed using the default value (0).

    Note 

    The recommended value for Session Limit Overload Protection has to be derived by Cisco Account representative for each deployment.

    Enable Multi Primary Key

    Select this check box to allow two primary keys to be utilized by maintaining a map of each separate primary key and storing the 'true' multi-primary key as a UUID related to the two maps. Changing this setting has a negative performance impact and should only be done at the request of the BU. Recommendation is to keep Enable Multi Primary Key unchecked.

    Default is unchecked.

    Enable Number Normalization

    Select this check box to enable number normalization under system configuration. The following fields are displayed under Number Normalization List:

    • Number Type - Type of IMSI/MSISDN.

    • Number Length - Length of the normalized IMSI/MSISDN.

    • Number Prefix - Prefix to be normalized from the number.

    Cluster link

    Click this link to create a cluster under this system.

    Current System Link

    Click this link to make a copy of this system, with its clusters and instances.

  4. If the created system needs to be used, then after publishing, the following property needs to be updated in the qns.conf configuration file:

    -Dcom.broadhop.run.systemId=<system name>

    where <system name> is the system name defined in the Step 3.
