A radiotelephone method includes detecting other mobile stations and identifying possible relay candidates among the other mobile stations. The method then includes communicating information about the candidates to a base station. Communication with a second mobile station is requested of the base station at a first mobile station. If the first mobile station and the second mobile station are physically close, the base station instructs the first mobile station and the second mobile station to establish direct communication.
