LRF 在 IMS 中示意 專案說明 : 本產品使用MI Interface(SIP)與E-CSCF介接 產品說明 : 客製化LRF , UE dial 110/119/112 定位轉碼到當地警消單位PSAP LRF - Location Retrieval Function In the 3GPP IMS, the LRF retrieves location information for users that have initiated an emergency session. This location information is provided to the E-CSCF (Emergency CSCF) in order to facilitate routing of the call to a suitable PSAP (Public Safety Answering Point). E-CSCF - Emergency – Call Session Control Function The E-CSCF is a specialist platform which is designed to facilitate support for emergency services dialling. In this capacity, the E-CSCF will take in requests from the P-CSCF (Proxy CSCF) and S-CSCF (Serving CSCF) and route these emergency session requests to a suitable onward destination such as a PSAP (Public Safety Answering Point). In order to achieve this, the E-CSCF can use the services of the LRF (Location Retrieval Function). Ref:  http://www.3gpp.org/ https://www.ietf.org/rfc/r...
