Position reporting method for a mobile terminal in a mobile communication network
First Claim
1. A method for reporting a position of a mobile terminal to a mobile communication network during a packet data session, said method comprising:
- starting a packet data session;
transmitting packet data to said mobile communication network during said packet data session;
determining said position of said mobile terminal;
sending position information representative of said position of said mobile terminal to said mobile communication network by multiplexing said position information with packet data otherwise being transmitted during said packet data session;
setting first and second timers, wherein said second timer is set to expire subsequent to said first timer;
waiting for an access event following expiration of said first timer; and
if an access event occurs after said first timer expires and before said second timer expires, sending said position information representative of said position information of said mobile terminal during said access event.

Abstract
A mobile terminal reports its position to the mobile communication network on a regular and unsolicited basis. Position reports are combined with data, such as channel quality measurements or packet data, that is otherwise being transmitted by the mobile terminal to the mobile communication network to reduce the number of access events and avoid collisions on shared channels. Position reports may give position as an absolute position, a relative position, or alternatively may be an indication of no change in position. Other position-related information, such as velocity and acceleration, may be included in position reports and used to vary the frequency of the position reports.

3. A method for reporting a position of a mobile terminal to a mobile communication network during a packet data session, said method comprising:
-
starting a packet data session;
transmitting packet data to said mobile communication network during said packet data session;
determining said position of said mobile terminal; and
thereafter, sending position information representative of said position of said mobile terminal to said mobile communication network by bundling said position information with packet data otherwise being transmitted during said packet data session into a single transmission event;
wherein said sending position information comprises;
waiting to send said position information to said mobile communication network until there exists other packet data to be transmitted from said mobile terminal to said mobile communication network;
bundling said position information with said other packet data to produce a combined message;
transmitting said combined message as a single transmission event during said packet data session;
setting first and second timers, wherein said second timer is set to expire subsequent to said first timer, and wherein said waiting comprises waiting for an access event following expiration of said first timer.
