Abstract:
1. A base station apparatus which allocates communication bands for terminal units from an available communication band, and performs wireless communications with the terminal units using the allocated communication bands, comprising: a priority table storing priority information used for deriving a priority of the communication; a detecting part detecting a situation change concerning the communications; a band derivation part deriving communication bands required for the communications with terminal units to communicate, when the detecting part detects the situation change; a priority derivation part deriving priorities of the communications with the terminal units on the basis of the priority information stored in the priority table; an allocating part allocating the communication bands derived by the band derivation part for the wireless communications with the terminal units in the order of descending priorities derived by the priority derivation part; a judging part judging whether or not a total of the communication bands which are required for the communications with the terminal units and are derived by the band derivation part exceeds an available communication band; a limiting part temporarily limiting at least one of the communications of the terminal units in the order of ascending priorities derived by the priority derivation part, when the total of the required communication bands is judged to exceed the available communication band, wherein the limiting part causes the terminal units to interrupt the communications, the band derivation part derives the communication bands required for the communications with the terminal units including at least one terminal unit in which the communication is interrupted, and the priority derivation part derives the priorities of the terminal units including the at least one terminal unit in which the communication is interrupted, the base station apparatus further comprising: a resumption part resuming the communication of the at least one terminal unit, when the judging part judges that the total of the required communication bands does not exceed the available communication band, or when the limiting part does not target the at least one terminal unit in which the communication is interrupted, and
