COMMUNICATION CAPACITY MANAGEMENT DEVICE, RADIO COMMUNICATION SYSTEM, COMMUNICATION CAPACITY MANAGEMENT METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem of a shortage of communication capability or balance without letting a user consciously operate when performing communication through a radio communication line having restrictions on communication capacity.SOLUTION: An additional purchase processing unit performs processing for additional purchase of communication capacity with expiration date. A residual capacity management unit performs management of residual quantity of communication capacity including additional purchase communication capacity which is the additionally-purchased communication capacity with expiration date. A purchase content specification unit specifies additional purchase communication capacity. A purchase condition determination unit, in the case where any radio communication line out of a plurality of radio communication lines sharing communication capacity satisfies a condition for purchase of additional purchase communication capacity, determines that other radio communication lines sharing communication capacity also satisfy the purchase condition. When it is determined that the condition for purchase of additional purchase communication capacity is satisfied, the additional purchase processing unit performs processing for purchase of additional purchase communication capacity.SELECTED DRAWING: Figure 1
