Abstract
A microcellular communication system which broadcasts its local channel block, including the control channels allotted from a total channel block to the microcellular system, on all control channels being used by the system. A mobile unit seeking access to the microcellular system initially searches the total channel block in an effort to receive the local channel block information broadcast by the microcellular system. The mobile unit compares received local channel block information with stored total channel block information and replaces its memory content with the newly received information. Periodic searching of stored channel block information is conducted to verify that the mobile unit has the relevant channel block information for the local microcellular system.
