Place Associations

A Place Association allows Places to be grouped in ways that make sense for DSR Applications. A Place Association is a collection of one or more Places that have a common Type. A Place can be a member of more than one Place Association.

The PCA application defines two Place Association Types:

• PCA Binding Region

  As illustrated in Figure 2-3, the PCA application defines a Region to include all Sites that are part of the PCA network. This provides a scope for the Binding database, which is accessible to all PCA Sites in the PCA network.

• PCA Mated Sites
  As illustrated in Figure 2-3, pairs of PCA Sites are grouped together. Each Place Association with a PCA Mated Sites type includes exactly 2 sites. PCA Mated Sites has several attributes:

  • Hosts an instance of the PCA Session database
  • Hosts client Diameter connections for Policy Clients at both Sites
  • Hosts PCRF/OCS Diameter connections for PCRFs/OCSs at both Sites in the Mated Pair
