SonyEricsson’s Spatial Triggers

Currently, LBSs require a user to actively request position information, by sending an SMS, for example. Spatial Triggers, however, is a network function that automatically informs applications when users meet certain conditions. …

The Spatial Triggers function is an Ericsson proprietary solution, which works for both GSM and WCDMA users and supports CGI, CGI/TA or Cell ID positioning.

Information related to Spatial Triggers is stored in a database server. The information contained in that database consists of trigger criteria defining the location conditions that must be fulfilled in order to inform the client. The following criteria can be defined:

• mobile terminal entering an area; 

• mobile terminal leaving an area; 

• two mobile terminals within a certain distance of each other.
