Abstract: A process for consolidating location-dependent information in a two-way radio system includes determining a geographic location of each subscriber unit in a group of subscriber units active within a radio frequency (RF) coverage area of a base station (BS), determining a single representative geographic location for the group of subscriber units based on their geographic locations, requesting location-dependent information from a content provider using the representative geographic location, and causing the location-dependent information to be broadcast within the RF coverage area.

Abstract: A radio controller monitors a radio channel for a first period of time and determines a first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during that time. Responsive to determining that the first indication is above a predetermined threshold indicative of an interference condition, causing an instruction to be broadcast identifying a subset of subscriber devices allowed transmitting random access requests on the radio channel. The radio controller monitors the radio channel for a second period of time and determines a second indication during that time. If the second indication is an improvement over the first indication, the radio controller determines that the interference condition is caused by the mass random access event.
