Early Binding

An Early Binding is a binding for which a session initiation request has been received, but no session initiation answer has been received. The PCRF for an Early Binding in unknown. A given IMSI-APN combination can have only one early binding. The Early Binding serializes binding creation attempts for a given IMSI and APN. Subsequent session initiation requests for an IMSI-APN combination for which an Early Binding exists are held until the Early Binding becomes a Final Binding.

Early Binding Master

A binding capable session initiation request that creates a new Early Binding is referred to as the Early Binding Master for that binding. A given Early Binding can have only one master. The term master is used to convey that no subsequent binding capable session initiation requests for that binding can be routed until the master session is successfully answered by a PCRF.

Early Binding Slave

A binding capable session initiation request that matches an Early Binding is referred to as an Early Binding Slave for that binding. There may be multiple slaves for a given Early Binding. The term slave is used to convey that the slave session request must wait for the master session request to be completed before it can be routed.
