Setting GCS ARP Settings

The Group Communication Service (GCS) feature allows you to prioritize group communication sessions from an Application Function acting as a Group Communication Service application server. Prioritizing traffic from GCS application servers allows public safety groups, like police and emergency medical services, to communicate over the public network when the network is congested.

The values configured through the CMP system, using the process below, are used as the default GCS Allocation and Retention Policy (ARP) values for all MPE devices associated with the CMP system when a session is identified as a group communication session and the ARP values are not defined through policy.

To enable or disable prioritization of group communication sessions:

  1. From the Global Configuration section of the navigation pane, select Global Configuration Settings.

    The content tree displays a list of global configuration settings.

  2. From the content tree, select the GCS ARP Settings folder.

    The Priority Value page opens in the work area.

  3. Click Modify.

    The GCS ARP Settings page opens.

  4. Enter values for the configuration attributes:
    1. Priority Value—Defines the relative importance of a resource request. Enter a value from 1 to 15. The default is 1.
    2. Preemption Capability—Defines whether a service data flow can get resources that were already assigned to another service data flow with a lower priority level. Select Enable or Disable from the list. The default is Enable.
    3. Preemption Vulnerability—Defines whether a service data flow can lose the resources assigned to it so that a service data flow with a higher priority level can be admitted. Select Enable or Disable from the list. The default is Disable.
  5. Click Save.
The GCS ARP Settings attributes are configured.
