5. GSC 5 E911 History  The US FCC released a ‘Report and Order’ in 1996 (94– 102) to provide:  a callback number and cell/sector identification (‘Phase I’).  more accurate location (‘Phase II’).  This was revised in 1999 and allowed handset-based location technologies.  The TIA developed J-STD-034 with ATIS to address Phase I in 1997.  J-STD-036 was first published in 2000 to address Phase II. Revision B is now [under development].

6. GSC 6 J-STD-036 Reference Model

7. GSC 7 Callback  Providing the telephone number of the emergency caller allows calls to be made back after the emergency call (e.g. to obtain more information).  A pseudo-callback number is provided for non- subscribers, based on the ESN, IMEI or MEID. It allows identification of the caller, but not callback.  Callback uses standard inter-system call delivery (e.g. based on TIA-41).

8. GSC 8 Cell/Sector Identification  Identifies the cell from which an emergency call was made.  Provides crude location.  Helps route to the correct PSAP.  May be transmitted directly as an ESRD, or indirectly via an ESRK (followed by a database lookup).

9. GSC 9 Accurate Location  Network based solutions must provide 100 meter accuracy 67% of the time, 300 meters 95% of the time.  Handset based solutions must provide 50 meter accuracy 67% of the time, 150 meters 95% of the time.  Location (as lat/long) is usually provided after initial call setup.  Interim location may be provided during call setup to allow more accurate PSAP routing.

10. GSC 10 J-STD-036 Revision B  Joint effort between TIA TR-45.2 and ATIS WTSC (formerly T1P1).  Extends ‘interim location’ to GSM/UMTS. Also supports CDMA.  Interim location is used to provide more accurate PSAP selection, reducing misrouted calls.  Supports ‘uninitialized’ mobiles with MEID (CDMA replacement for ESN, based on IMEI).

12. GSC 12 Summary  TIA/ATIS J-STD-034 supports the US FCC Phase I Enhanced Wireless 911 mandate.  TIA/ATIS J-STD-036 supports the US FCC Phase II mandate, along with emerging wireless carrier/emergency call taker requirements.  [All major public wireless technologies used in the USA are supported.]
