Publication number: 20150234680Abstract: A task control unit executes a task according to execution request information for the task, which task is registered using a function provided by task control unit. The task control unit separately controls a task (P-Task) whose execution time is set by a programmer and a task (S-Task) whose execution time is set by a system so that the tasks do not interfere with each other. The task control unit executes plural S-Tasks while complying with their execution periods. By controlling tasks by the foregoing methods, energy is saved and a network load is reduced.Type: ApplicationFiled: October 31, 2013Publication date: August 20, 2015Applicant: NTT DOCOMO, INC.Inventors: Teppei Konishi, Hiroshi Inamura, Takeshi Kamiyama, Satoshi Kawasaki
