Abstract: A queue management device (30A/30B) receiving jobs transmitted from a plurality of user terminals (10A/10B) stores the jobs to a queue corresponding to a base in which the user terminal is disposed. Each of the jobs to be stored includes a request of securing license. The queue management device requests a job processing device (41) to secure a license corresponding to a job read from the queue. The job processing device replies whether or not the license can be secured to the request from the queue management device. The queue management device transmits the job, to which the license is secured, to the job processing device. With this processing, a license can be fairly allocated to requests from respective users without depending on timing at which the license is requested.
