The storage unit is configured to store therein a plurality of primary cipher keys, a plurality of pieces of device information, and a plurality of pieces of group information. The group call control unit is configured to perform a group call with radio devices belonging to a first group using a primary cipher key. The cipher key generation unit is configured to generate a secondary cipher key that is different from the primary cipher key when one or more radio devices belonging to the first group are selected during the group call. The group call control unit performs a temporary group call with the selected radio devices by switching the primary cipher key to the secondary cipher key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio device, control method of radio device, and non-transitory computer-readable recording medium","description":"A radio device includes a storage unit, a group call control unit, and a cipher key generation unit.
