Intelligent transport systems - eSafety - eCall HLAP in hybrid circuit switched/packet switched network environments

General information

50.60     Sep 21, 2023



European Norm

03.220.20     35.240.60  


In respect of 112-eCall (pan-European eCall) (operating requirements defined in EN 16072), this document defines the additional high level application protocols, procedures and processes required to provide the eCall service whilst there are still both circuit switched and packet switched wireless communication networks in operation.
NOTE The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in Europe, with the same technical standards and the same quality of services objectives by using a PLMN (such as ETSI prime medium) which supports the European harmonized 112/E112 emergency number (TS12 ETSI TS 122 003 or IMS packet switched network) and to provide a means of manually triggering the notification of an emergency incident.
