1、 TIA-1148 November 2011HRPD Support for Emergency Services NOTICE TIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assistin

2、g the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Publications shall not in any respect preclude any member or non-member of TIA from manufacturing or selling products not conforming to such Standards and P

3、ublications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. Standards and Publications are adopted by TIA in accordance with the American National Standards Institute (ANSI) patent policy. By suc

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
