location-based services in the mobile networks are introduced and deployed by
Internet companies. It leaves for telecom just the role of the data channel.
Telecom providers should use their competitive advantages and offer own

geo-messages. Geo messages let mobile users share location information as
signatures to the standard messages (e.g., email, SMS). Rather than let some
service constantly monitor (poll) the user location (as the most standalone
services do) or share location info within any social circle (social network
