The <b>OpenScape First Response Emergency Services Routing Proxy (ESRP)<b> is based on the OpenScape Voice and sits within the ESInet and provides emergency call routing services. An emergency call arrives at an ESRP from a Border Control Function (BCF) or another ESRP.  An ESRP makes routing decisions based on information in the incoming INVITE message (typically including the caller’s location or a reference to the caller’s location), on information returned from location and routing databases such as the LIS and ECRF, and the routing policies in effect at the time of the call. The ESRP makes what is referred to as a ‘next-hop’ decision and routes the call to a Public Safety Answering Point (PSAP) or another ESRP for further routing.

The OpenScape First Response ESInet/NGCS Solution is made up of a number of components that provide the Next-Generation Core Services (NGCS) for an emergency calling network. Typical customers for this solution would be national or regional government entities responsible for handling requests for emergency service (Police, Fire, Emergency Medical, etc.).

The OpenScape First Response ESInet/NGCS Solution consists of the following functional elements:

Border Control Function (BCF)

The OpenScape Border Control Function sits between external networks and the Emergency Services IP Network (ESInet) and provides a secure entry into the ESInet for emergency calls (and other calls) presented to the network. All traffic from external networks transits a BCF. The BCF incorporates firewall, admission control and session and media anchoring, as well as other security mechanisms to prevent deliberate or malicious attacks on Public Safety Answering Points (PSAPs) or other entities connected to the ESInet.

Typically, separate BCFs will be used on the ingress and egress sides of the ESInet. The BCF on the ingress side is referred to as the BCF-I and the BCF on the egress side is the BCF-E.

All OpenScape First Response solution components are implemented based on both North American (NENA) and European (ETSI/EENA) standards and can be deployed anywhere in the world.

Emergency Services Routing Proxy (ESRP)

The OpenScape First Response Emergency Services Routing Proxy (ESRP)<b> is based on the OpenScape Voice and sits within the ESInet and provides emergency call routing services. An emergency call arrives at an ESRP from a Border Control Function (BCF) or another ESRP. An ESRP makes routing decisions based on information in the incoming INVITE message (typically including the caller’s location or a reference to the caller’s location), on information returned from location and routing databases such as the LIS and ECRF, and the routing policies in effect at the time of the call. The ESRP makes what is referred to as a ‘next-hop’ decision and routes the call to a Public Safety Answering Point (PSAP) or another ESRP for further routing.
