G557:2014 Location Information for Emergency Calls
G557.3:2014 (.pdf, 276 KB) see Note below
Part 1 is an Index that describes the parts of G557.
Part 2 is the Standardised Mobile Service Area (SMSA) and Location Indicator Register. It is a pack of 5 compressed files (3,621KB) that define the SMSAs for use in the interim signalling of mobile caller location and 3 digit 'ABC' codes for caller location. These files were prepared in MapInfo (TM) and you will need relevant software to be able to read/view the files. For those unable to view map files there are also some spreadsheets with summary information available from this webpage.
Part 3 is the Location Independent Communications Service Location Indicator for Emergency Services Signalling Guideline (previously G629:2009). It specifies the industry procedures for the transfer of location information for Location Independent Communications Service (LICS) Services to Emergency Service Numbers.
NOTE: G557.3:2014 contains an editorial error in Table 1. The 'ABC' code for the rows in Table 1 other than "Nomadic Location Indicator" should be 98n, not 99n, where n is a digit. The use of 98n for "Nomadic" VoIP services is consistent with the 'ABC' code for "Location Independent Communication Services" in the spreadsheet 'List of SMSA and ABC Codes 22Apr09' (available above). The 99n 'ABC' codes are used for "Fixed Local Services". Communications Alliance is working to update G557.3 and correct the error.
Part 4 is the Mobile Location Information (MOLI) Processes For Emergency Calling And Rescue Coordination Guideline (previously G643:2012). It describes the processes to provide location information for an Emergency Call on request from an Emergency Service Organisation or the Australian Maritime Safety Authority.
Part 5 is the Push Mobile Location Information (MoLI) Interface To Enhanced Calling Line Identification System (ECLIPS) Specification. It defines an interface for the transfer of Push MoLI between a Mobile Carrier and ECLIPS for an Emergency Call.
G557:1999 (.zip, 3,241 KB) was a set of 46 compressed files that defined the SMSAs. It complemented G530:1999 Mobile Location Indicator for Emergency Services and G532:1999 Mobile Location Indicator - 13/1300/1800.
At the same time in 2002, two spreadsheets were made available for download:
- a list of all SMSA and ABC Codes (38KB); and
- a list of all SMSAs and the respective Codes that adjoin each SMSA (86KB).
In 2006 the spreadsheet with the list of SMSA Codes was updated and published. This modified the description of existing '98x' and '99x' ABC codes (used for VoIP, nomadic and fixed services) and made no changes to ABC codes for calls from mobiles. Therefore the spreadsheet with the list of adjoining SMSA Codes was not affected by the modifications.
In 2007 Communications Alliance updated the maps to remove unnecessary information. There was no change to the 3 digit ABC codes or to the list of adjoining areas.
In 2009 Communications Alliance updated the list of SMSA and ABC Codes to:
- replace “For Nomadic Services” with “For Location Independent Communications Services” as the heading for the 3 digit ‘ABC’ codes 98x for consistency with the amended Telecommunications (Emergency Call Service) Determination 2002;
- explicitly define as “Unallocated” the previously unallocated 3 digit ‘ABC’ codes within existing ranges of codes; and
- add “QLD” as the State/Territory field for the 3 digit ‘ABC’ code 565.
G557:2009 replaced G557:2007 and complemented G629:2009 Location Independent Communications Service Location Indicator for Emergency Services Signalling Specification which became Part 3 of G557:2014.
An associated document G606:2002 Standardised Mobile Service Area (SMSA) Register - Management Processes is available for download. It defines the processes and procedures relating to the management of the SMSA Register.
G606:2002 SMSA Register - Management Processes
G606:2002 defines the processes and procedures relating to the management of the Standardised Mobile Service Area (SMSA) and Location Indicator Register G557:2009 for use by the Australian public mobile telecommunications industry.
The SMSA Register is a pack of 46 compressed files that define the SMSAs for use in the interim signalling of mobile location.
The Guideline was reconfirmed in 2006, 2011 and 2016 and the next review is scheduled to occur in August 2021.
