Binding Key Priority

The Binding Key Priority defines search priorities for Alternative Keys that can be used to locate a subscriber binding.

The Binding Key Priority controls:

Which keys are stored for binding correlation
The order in which keys are searched for purposes of binding correlation

The priority determines the order used to find a binding for subsequent sessions. Alternative Keys with an assigned priority will be created with the binding if they are present in the session initiation message that created the binding. The Alternative Keys must be assigned a priority in order to be used to locate subscriber bindings. If any Alternative Keys are not assigned a priority, they will not be used to locate subscriber bindings even if the Alternative Key is present in the session initiation message.

The fields are described in Binding Key Priority elements.

On the Policy and Charging > Configuration > Policy DRA > Binding Key Priority page on the Active SOAM, you can change the Binding Key Type for Binding Key Priority 2, 3, and 4.

Note: Priority 1 for Binding Key Type IMSI is the highest priority and cannot be modified.

Enabling and disabling the binding key field depends on the value that you select for the Binding Key type.
