Abstract: A dynamic call based user ID allows subscriber units to be shared amongst a plurality of users or used for a plurality of roles/uses. A voiced call sign is transmitted by a calling subscriber unit to a targeted subscriber unit. A pattern in the voice transmission of the calling unit is detected, and the voiced call sign is compared to a list of pre-stored call signs. When a match between stored calls signs and the current call sign occurs, the calling subscriber unit saves the current call sign. Fixed network equipment (FNE) then associates the saved current call sign with a subscriber unit ID (SUID) of the calling unit. The dynamic association between the call sign and the SUID allows the subscriber unit to be shared amongst different users and for different uses/roles.

Abstract: A system and method provides intermodulation (IM) interference mitigation in a two-way radio receiver (100) by utilizing various states of an automatic gain control circuit (AGC) (118) controlled by RSSI levels and timers.
