Control Channel Acquisition

When first powered up, an iDEN mobile radio scans selected iDEN frequencies and locks on to the designated control channel. The control channel carries information ontinuously broadcast by the fixed end system regarding system identification and timing parameters for the mobile radio to use when it operates on the system. The control channel also defines the maximum transmit power that radios on the system may use.

Mobile Synchronization

In its operational mode, the mobile radio aligns its frequency and transmit timing to the outbound signal received from the fixed end system.

Mobile Registration



Each mobile radio in an iDEN system is identified by an international mobile station identifier (IMSI), which is assigned to it when it is first placed in service and performs an initial registration with the fixed end system. When making its registration request, the mobile radio supplies its international mobile equipment identifier (IMEI) to the fixed end system. After determining the validity of the IMEI, the fixed end station assigns an IMSI to the subscriber radio
