• The Open Geospatial Consortium (OGC) – Since 1994, – Delivering open standards to the global geospatial community, – A huge investment has been made by Governments, commercial,

not-for-profit, research and academic organizations developing and implementing OGC standards.

SHORT MESSAGES SYSTEM

SMS has been adopt on almost every mobile phone and is rapidly used with a trillion-scale volumes

People communicated with pure text, HTTP URL is supported on most smart phone

However, lacks of common and open standard for exchanging location information

Operators Need New SMS-based Services

• According to the latest forecasts from Informa Telecoms & Media, SMS will remain a significant source of revenues and traffic for mobile operators on a global basis until at least 2015. – Global SMS revenues: US$136.9b in 2015 (US$105.5b in 2010)

– Global SMS traffic: 8.7 trillion messages in 2015 (5 trillion in 2010)

• However, growth in SMS revenues is slowing or falling, particularly in developed markets, and mobile operators may lose a significant cash cow if they do not enable the new and innovative SMS-based services.

OGC Open GeoSMS

The OGC Open GeoSMS standard defines an encoding for location information over Short Messages System (SMS).

OGC Open GeoSMS

Defines a short messaging service (SMS) encoding to exchange lightweight location information between different mobile devices or applications.

Open GeoSMS encoding for location is compatible with other OGC standards, such as those for sensor webs and earth imaging.

It is also compatible with other standards such as the OASIS Common Alerting Protocol (CAP) standard and the IETF RFC Presence Information Data Format Location Object (PIDF-LO)

- Possible harmonization with GeoURI

Conformance Testing

• Specific conformance tests for an Open GeoSMS need to be defined on the concrete service level in order to ensure full interoperability. Thus, the abstract test suite defined herein only ensures general interoperability. A Core part of Open GeoSMS implementation shall satisfy the following characteristics to be minimally conformant with this encoding standard.

Test Purpose: To verify that the format of an SMS is conformant with the mandatory requirements of Open GeoSMS.Test Method: To verify that the first line of an SMS shall be an http/https URI with the postfix as “&GeoSMS” and the valid location value for the first parameter that is conformant with Requirement 1, 2 and 3 in chapter 5.1.Test Example: The following example conforms to a valid Open GeoSMS. http://maps.geosms.cc/showmap?geo=23.9572,120.6860&GeoSMSReference: Subclause of chapter 5.1 according to Requirement 1, 2 and 3.Test Type: Basic and Conformance
