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 1, 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 Pair
As illustrated in
Figure 1, pairs of PCA Sites are grouped together as Mated Pairs. Each Place Association with Type of PCA Mated Pair includes exactly 2 sites. A PCA Mated Pair has the following attributes:
- Hosts an instance of the PCA Session database
- Hosts client Diameter connections for Policy Clients at both Sites in the Mated Pair
- Hosts PCRF/OCS Diameter connections for PCRFs/OCSs at both Sites in the Mated Pair
