BCF
Border Control Function
BCF-like functions sit at trust boundaries between originating networks, ESInet domains and PSAP-facing networks. The function may resemble session border control, but emergency use adds routing, availability, logging and policy expectations that ordinary enterprise SBC deployments may not satisfy.
What it does
A Border Control Function protects NG112 network boundaries and controls emergency session interconnection.
The BCF helps secure and normalize emergency sessions as they cross organizational or network boundaries.
How it works
- Terminates or mediates SIP signaling at an interconnect boundary.
- Applies topology hiding, admission controls and protocol normalization.
- Supports secure transport and operational logging.
Key interfaces and protocols
- SIP
- TLS
- SRTP where used
- Certificate management
- Interconnect policy
Systems it interacts with
- ESInet
- ESRP
- Originating carriers
- PSAP networks
- Security monitoring
Common failure modes
- Certificate expiry breaks trusted interconnect.
- Overly strict normalization strips location headers.
- Rate limits block real emergency surges.
- NAT or media anchoring breaks audio/video.
Implementation considerations
- Test location-bearing SIP through the boundary.
- Keep security controls aligned with emergency availability.
- Do not assume vendor SBC defaults meet NG112 behavior.
