ATIS-0700015.v003 8 Clause 6 provides basic

32、 assumptions, defines requirements via reference to 3GPP specifications, and includes any differences (e.g., extensions or restrictions) to these specifications. Clause 7 provides an architectural description that is based on the IMS architecture defined for 3GPP and the ESInet architecture for NENA

33、 i3 Ref 100. Clause 7 also describes some extensions to the 3GPP IMS architecture applicable to operation in North America, and provides a brief definition of each of the main architectural entities within IMS originating network and the emergency services networks. Clause 8 provides a description o

34、f the procedures and signaling applicable to location retrieval and emergency call origination to a NENA i3 ESInet and legacy emergency services network. Clause 9 provides a description of any differences to existing standards including use of particular options regarding treatment of different acce

35、ss types for support of IMS Emergency Calls in North America. Annex A provides a normative SIP INVITE profile for the ici reference point between the IBCF in the IMS originating network and the BCF in the ESInet. Annex B provides a normative description of using MLP between the LRF and LS for L0. An

36、nex C provides an informative description of location acquisition and conveyance based on the 3GPP Control Plane and OMA User Plane location solutions for LTE and HSPA access. Annex D provides an informative description of emergency call routing by an IMS originating network. Annex E is an informati

Annex F is an informative Annex that describes some of the access network types for which the procedures and requirements in this document are applicable, with specific reference to IMS interaction, handover, and support of location. Fo

38、r each access type, capabilities and requirements are summarized with references to the applicable standards in which they are fully defined. Annex G is an informative Annex that describes a set of use cases for an IMS emergency call origination, to legacy PSAPs as well as IP-capable PSAPs, routing

39、on geographic location or cell site/sector, and use of location-by-value or location-by-reference. Annex H is an informative Annex that describes the UE originating a call with location-by-reference. 6 Assumptions with North American extensions/restrictions. 3. Emergency calls egress to either a leg

40、acy emergency services network or an IP-based emergency services network (i.e., NENA i3/NG9-1-1 ESInet Ref 100). 4. For MMES sessions, the Common IMS network will determine the appropriate emergency services network (e.g., a NENA i3 ESInet). 5. The media type will have to be considered when selectin

41、g the appropriate emergency services network. 6. MMES sessions beyond voice and GTT cannot be routed to legacy emergency services networks. 7. Each User Equipment contains an IMS client. 8. A UE may or may not be location aware. 9. Methods of location determination are outside the scope of this stan

42、dard. 10. If there is a civic address associated with the UE, it is validated; the validation process is out of the scope of this standard. 11. An Associated Location is used in some wireless routing scenarios where the cell address or cell centroid cannot be used to route a call to the ESInet or th

43、e Selective Router. 12. An originating network and user equipment (UE) may support some or all media types. 13. It may be possible to negotiate the users indicated desired language(s), per media stream and/or session, in order of preference. ATIS-0700015.v003 9 14. Voice and GTT sessions are expecte

44、d to be maintained when a UE with an active IMS MMES moves out of IMS emergency coverage. 15. This standard only addresses emergency service use of IMS services. It does not address use of legacy services (e.g., SMS to 9-1-1) in an emergency or the interworking of legacy services with IMS. 6.2 Requi

45、rements The Architectural Principles defined in section 4.1 of 3GPP TS 23.167 Ref 1 and 3GPP TS 24.229 Ref 2 apply to this standard with the differences and clarifications noted below. Parts of that section are copied as required to illustrate the differences and clarifications. _ 3GPP TS 23.167 Ref

46、 1, section 4.1: “If required, the E-CSCF shall be able to forward the location information to the LRF for validation of geographical location information in the case that the geographical location information is included by the UE over any access network type.” Architecture-Principles-010 The LRF s

47、hall not validate geographical location information during an emergency session. NOTE: Any civic location must be validated against an emergency services validation database prior to the origination of an emergency session. Geo-coordinate locations cannot be validated. Geo-coordinate locations can o

48、nly be verified to be within expected boundaries. _ 3GPP TS 23.167 Ref 1, section 4.1: “The E-CSCF is the IMS network entity, which is responsible to route the request to an emergency center/PSAP or BGCF based on location information and additionally other information such as type of emergency servi

49、ce in the request.” Architecture-Principles-020 The E-CSCF shall route the emergency session (e.g., to the MGCF via BGCF for the legacy ES network or IBCF for the ESInet) based upon routing information received from the LRF. _ 3GPP TS 23.167 Ref 1, section 6.2.1: “Reject/allow anonymous emergency requests.” P-CSCF-010 Based on the operators policy, the P-CSCF shall allow anonymous emergency requ
