Abstract
A messaging server receives a sharing message from a sharer client indicating that the sharer client is offering to provide live location information. When the messaging server receives a subscription request from a receiver client indicating a request to receive live location information shared by the sharer client, the messaging server sends a location request to the sharer client. The location request requests live location information from the sharer client. The sharer client determines its location using a location module and sends live location information to the messaging server in response to the request. The server sends the live location information received from the sharer client to the receiver client. When no receiver clients send subscription requests, the sharer client does not send live location information, thereby preserving power by limiting use of the location module.
