In particular HRPD 2, 6, 7 is suppor
30、ted. For cdma20001-1X access networks the traditional circuit switch approach for emergency services 5 should be used. All other IP based support for Emergency Services has been included in the Common IMS work with 3GPP. Requirements can be found in 4. Stage 2 descriptions can be found in 3. 1cdma20

46、 requirements on the IP-CAN are covered by the following HRPD specific requirements: HRPD networks shall authenticate the UE in accordance with normal authentication procedures, i.e., A12 and PDSN authentication. For support of unauthorized emergency callers, A12 support is optional, PDSN authentica
47、tion is required. HRPD networks may allow limited access to UEs that wouldnt normally be authenticated, but which provide authentication credentials specific to emergency service. In this case, the HRPD network allows access to UEs using emergency NAIs of the form and for PDSN and A12 authenticati
48、on respectively. HRPD networks shall provide data access of the type requested by the UE, i.e., Simple IPv4, Simple IPv6, Mobile IPv4, and Mobile IPv6. The HRPD network shall not provide L2TP service to the UE. This is general requirement and not only applicable to emergency services. HRPD networks
49、shall provide the address of the local P-CSCF via DHCP or DHCPv6 depending on the type of IP address acquired by the UE. This could be an IP (v4 or v6) address or a SIP URI. HRPD networks shall provide Carrier-ID information to the UE via DHCP or DHCPv6 so that the UE may determine if it is roaming or not. Carrier-ID is defined in Section 5. 4.2 UE Specific Behavior for Emergency Calls over HRPD For the specific case of an emergency call over HRPD the UE shall adhere to the following
