Abstract
Techniques to efficiently broadcast position location data (PLD) from a base station 120 to a number of terminals 110. In one aspect, PLD messages are classified into groups, and each group is broadcast in a different manner. F or example, a first group of messages for PLD related to the base station 120 i s broadcast in an unscheduled format, and a second group of messages for PLD related to GPS satellites 130 is broadcast in a scheduled format. In another aspect, a schedule for the second group describes the specific PLD elements selected for broadcast, their broadcast order, and the specific time interva ls of their broadcast. The schedule is valid for a particular scheduled time interval, and the scheduling table is broadcast multiple times during the schedule time interval to allow the terminals 110 to quickly retrieve the schedule and ascertain what PLD information is being broadcast and where to look for specific PLD elements.
