The group communication method includes: scrambling data information of a message by using corresponding scrambling information according to a message type and/or a message transmission range; wherein, different message types and/or message transmission ranges correspond to different scrambling information. Therefore, internal members or peripheral devices of a group may selectively receive messages of different types or different target ranges. Hence, not only messages may be ensured to be accurately received by corresponding receivers, but also security of internal message may be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Group communication apparatus and method and communication system","description":"This disclosure provides a group communication apparatus and method and a communication system.
