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.
