OverviewHigh Probability of Completion (HPC) features comprise a set of functionalities that provide an enhanced probability of call completion to authorized Government Emergency Telecommunications Service (GETS) and Wireless Priority Service (WPS) users during network stress and/or congestion.

There are two methods in HPC call classification: - Early HPC classification—an HPC call is recognized based on the received SIP RPH content in the incoming INVITE or the code point in Calling Party's Category (CPC) parameter of the ISUP-MIME. For ANSI, the CPC parameter is National Security/Emergency Preparedness (NS/EP) and for ITU, the CPC parameter is International Emergency Preference Scheme (IEPS).
- Late HPC classification—An HPC call can also be recognized by PSX during analysis of the Called Party Number.
HPC capable switches such as GSX9000 enable HPC calls to receive additional network support to increase the chances of successful call completion. For more information on GSX9000’s GETS and WPS feature, refer to GSX documentation Support for Government Emergency Telecomunications Service and Wireless Priority Service. The SBC supports a subset of GSX9000's HPC capabilities and the capabilities are as follows: - HPC call classification that is, early or late HPC classification.
- Call Admission Control (CAC) treatment: ingress CAC for early HPC classified calls and egress CAC treatment for early and late HPC classified calls.
- The Resource-Priority header (RPH) is used for treating and marking SIP calls as HPC calls.
- Network Wide HPC (NW-HPC) License enforcement.
