PROBLEM TO BE SOLVED: To provide an onboard communication system and a mobile communication control method which are capable of early stage detection of failure. SOLUTION: In the onboard communication system formed of a constitution which connects among a plurality of onboard communication devices in the shape of a link, when the start of the system is detected (step S1), a new topology different from the last topology is determined (step S2) and a logical connecting topology is set in accordance with the determined new topology (step S3). After building new topology, the occurrence of interruption of communication or malfunction of communication is monitored and when the interruption or malfunction of communication is detected (Yes in step S4), the new topology different from the last topology is determined and switched, thereby a topology employed for communication is reconstructed (step S5). After that the continuation of communication by the new topology is effected, the occurrence of failure and information indicating the occurrence of failure and the place of failure are informed to a user (step S6).
