Overall Applicability Uniform Resource Name (URN) for emergency and other Well-Known Services are well defined within RFC5031 . There are also existing proposals for automatic and manual ecall IN-Vehicles which defines their own URN's and additional procedures for vehicle specific eCalls. Due to the existing telecommunication world and their implementations a combination of both is needed. Due to the fact that only one URN can be used within the request line of a SIP Message a new approach is needed. Therefore this document proposes to extend the existing URN's with an extension to reflect this. This draft should be seen as proposal which could be incoperated into draft-rosen-ecrit-ecall-10  after discussing this approach 2. Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 . 3. Overview RFC5031  defines URN values for emergency calls. The values for the SOS subtree are sos.ambulance, sos.animal-control, sos.fire, sos.gas, sos.marine, sos.mountain , sos.physician, sos.poison and sos.police  proposes two additional URN for ecall. automatic and ecall.manual the sub-services 'sos' as specified in Section 4.2 of RFC5031 . Within the existing implementation in GSM networks for emergency call as specified in 3GPP TS 22.101  the following requirements and code points are described: --------------------------------------------------------------------- --- Jesske Expires January 16, 2014 [Page 2] Internet-DraUniform Resource Name (URN) extension for automat July 2013 It shall be possible to initiate emergency calls to different emergency call centers, depending on the type of emergency. The following types of emergency calls shall be possible: o Police o Ambulance o Fire Brigade o Marine Guard o Mountain Rescue o Manually Initiated eCall o Automatically Initiated eCall .... It shall be possible to tie any emergency call number to any single emergency call type or to any combination of emergency call types. -------------------------------------------------------------------- This means in practice that a emergency Call Center from police must differentiate between automatic and manual eCalls. Same belongs to the other types like fire brigade Marine Guard ect. Requirement: Req-1: It shall be possible to tie a manually initiated eCall with different type of emergency type i.e. Police, Ambulance, Fire Brigade, Marine Guard and Mountain Rescue. Req-2:It shall be possible to tie a automatically initiated eCallC with different type of emergency type i.e. Police, Ambulance, Fire Brigade, Marine Guard and Mountain Rescue. These requirements will not allow a second different URN Format as described in draft-rosen-ecrit-ecall-10 . This draft adds two additional URN urn:service:sos.ecall.manual and urn:service:sos.ecall.automatic Which allows to address the ecall itself. But the requirement in 3GPP TS 22.101  described will not be satisfied. Therefor this document proposes an other format of the URN Jesske Expires January 16, 2014 [Page 3] Internet-DraUniform Resource Name (URN) extension for automat July 2013 4. IANA Consideration IANA is requested to register the URNs described below under the sub- services 'sos' registry defined in Section 4.2 of RFC5031 4.1. sublabel for sos service and the related subservices An additional sublabel for sos and the 5 base values of police, ambulance, fire, mountain are defined. .ecall This sublevel indicated that an ecall has been triggered. .automatic This sublevel indicates that an eCall had been triggered automatically. This could be a sensor-controlled measuring of heat or pressure in case of car accidents or fire situations. .manual This sublevel indicates that an eCall had been triggered based on the manual interaction of a person.
