A method and system for communicating within a wireless communication network ( 200 ) is provided. The communication between Portable Subscriber Units (PSUs) ( 104 and 106 ) by using a Vehicular Repeater ( 110 ) over a conventional communication link ( 102 ) is attempted ( 404 ). If the conventional communication link attempt fails ( 406 ), the communication is initiated directly from one PSU ( 104 ) to at least one other PSU ( 106 ) by using a direct channel link ( 202 ).
