Abstract
A protocol converter or translator between ANSI-41 ORREQs and VoIP V2 messaging. The protocol converter may alternatively (or also) provide conversion between GSM MAP and VoIP V2 messaging. Interaction of VSPs with a Mobile Positioning Center (MPC) or a Gateway Mobile Location Center (GMLC) is permitted, as is interaction of wireless carriers with a VoIP Positioning Center (VPC). In this way existing GMLCs or MPCs may be used to service VoIP 9-1-1 calls. Moreover, operators of VoIP Positioning Centers (VPCs) who implement wireless offerings can re-use their existing VPCs to service wireless 9-1-1 calls.
