Description

Group management method and device and wireless communication terminal Technical Field The present disclosure relates to the field of communications technologies, and in particular, to a group management method, apparatus, and wireless communication terminal. Background With the rapid development of wireless communication technology, the communication networking technology is widely applied in the fields of Internet of things, intelligent transportation, wireless sensor networks and the like. These systems often consist of a plurality of nodes, which are connected to each other by wireless communication to realize data transmission, resource sharing and cooperative work. In a distributed network, each node has certain autonomy and decision-making capability and participates in the organization and management of the network. In an ad hoc network, in order to ensure secure transmission of information inside a group, encryption processing is usually performed on the group, that is, each group has a specific group key, and only group members can acquire and decrypt the information inside the group. Conventional group management methods often rely on a fixed node to take care of the sending of the group key and the distribution of the management rights. When the fixed management node cannot work normally due to reasons, the group key can not be updated or sent in time, so that the normal communication of the group is affected. Furthermore, conventional ad hoc networks often rely on a single control center or predefined rules, which lack flexibility to accommodate rapidly changing network environments. Particularly, when the network structure or scale needs to be dynamically adjusted, the joining process of the nodes is difficult to effectively manage, and the requirements of the dynamic change of the group members cannot be met. Therefore, how to achieve efficient sending of group keys and reasonable allocation of management rights is a technical problem that needs to be solved. Disclosure of Invention According to a first aspect, a group management method is provided, the method is applied to a first node in a target group, the method comprises broadcasting authority request information on a working channel, the authority request information comprises identification information of the first node, the authority request information is used for requesting to acquire management authorities of the target group, the management authorities comprise authorities for sending group keys to nodes outside the target group, voting state information is acquired, the voting state information comprises identification information and voting information of participating voting nodes, the voting information represents approval or rejection, and under the condition that the voting state information accords with a first preset condition, the first node is determined to acquire the management authorities of the target group, and the first preset condition comprises the fact that the number proportion of the approval information is larger than a first preset value. When the voting state information is acquired, the identification information and the voting information of the participating voting nodes can be collected, and the decision result of most nodes in the network can be accurately reflected by counting the number of the nodes which agree with the first node to acquire the management authority of the target group. When the voting state information accords with the first preset condition, the first node can be determined to obtain the management authority of the target group. The adoption of the decision mechanism based on majority agreement realizes the decentralization scheme, is beneficial to reducing the control of a single node on the networking process, breaks the limitation of a single control center or a predefined rule in the traditional network construction, ensures that each node in the network has the right to participate in voting, jointly determines the authority allocation and the network structure of the network, effectively allocates the management authority of a group, and improves the stability of the self-organizing network. The decentralization characteristic is beneficial to reducing the risk of single-point faults and improving the robustness and the attack resistance of the network. Meanwhile, a distributed decision process is supported, and each node in the target group can respond to the authority request information of the first node in parallel, so that the decision efficiency is improved. In one implementation, after determining that the first node obtains the management authority of the target group, the method further includes broadcasting group information of the target group on a common channel, where the group information includes channel parameters of the working channel, receiving networking request information of a third node, where the networking request information is used to request to joi
