Virtual-environment-based object construction method and method and readable storage medium

The invention discloses a virtual-environment-based object construction method and device and a readable storage medium, and relates to the field of virtual environments. The method is applied to a terminal provided with a camera. The method comprises the steps that an environment interface is displayed; shooting operation is received, three-dimensional information of a to-be-collected object iscollected, and a feature point cloud of the to-be-collected object is obtained; position input operation is received, and the display position of the target object is determined; according to the shooting operation and position input operation, the target object is display at the display position in the virtual environment. By means of a camera of the terminal, the collected object is shot, afterthe three-dimensional information of the to-be-collected object is collected, a voxel block is filled according to the three-dimensional information, and the target object is generated and displayed at the display position; the problem that when a player manually construct the target object, the structure of the voxel block cannot be accurately controlled, and then object construction fails is avoided, and the object construction efficiency and accuracy are improved.

Method for establishing control channel in cognitive radio network

The invention discloses a method for establishing a control channel in a cognitive radio network. The method for establishing the control channel in the cognitive radio network comprises the access ofan available channel, the exchange of the control information and the establishment of a data transmission channel. The method for establishing the control channel in the cognitive radio network comprises the following steps: perceiving an available frequency band of an unauthorized user and the density information of the frequency band first before the unauthorized user performs the establishment of the control channel; then accessing the available channel according to the channel jump sequence; opening the channel competition mode when the data is to be transmitted; sending a RTS packet frame with the available channel and the channel density information after the channel competition is successful; and determining the data transmission channel between the unauthorized user and the destination node according to the public available channel and the density information when the destination node receives the RTS packet frame. The invention effectively solves the problem of the low efficiency of frequency utilization caused by the uneven distribution of the unauthorized users in the traditional cognitive radio networks; in addition, the control channel is separated from the data transmission channel in the method for establishing the control channel in the cognitive radio network, therefore, the opportunity to try to establish the control channel can be increased.

Bearer establishment method, device and system

The embodiment of the invention provides a bearer establishment method, a device and a system, relates to the field of communication, and is used for improving the success rate of establishing a proprietary bearer by a terminal. The method comprises the following steps: a gateway sends a second message to a PCC service management server; wherein the second message comprises a second bandwidth rate, and the second bandwidth rate is a bandwidth rate supported by the gateway; the PCC service management server receives a first message sent by the OTT server; wherein the first message comprises a first bandwidth rate, and the first bandwidth rate is a bandwidth rate requested by the OTT server for the terminal; matching the first bandwidth rate with the second bandwidth rate; wherein the secondbandwidth rate is a bandwidth rate supported by a gateway corresponding to the terminal; if the first bandwidth rate is not matched with the second bandwidth rate, adjusting the first bandwidth rateaccording to the second bandwidth rate to obtain a third bandwidth rate; wherein the third bandwidth rate is used for establishing a bearer of the terminal; and sending the third bandwidth rate to theAAC network element by the PCC service management server. The method is used for establishing a proprietary bearer for a terminal.

Reliable mobility RPL routing method based on link energy saving

The invention provides a reliable mobile RPL routing method based on link energy saving, and belongs to the technical field of wireless sensor network communication. The whole communication process is divided into three stages: a detection and transmission stage, a reaction and prediction stage and an announcement stage. The method comprises the following three innovative mechanisms: modifying a control message frame format, selecting a father node by combining priorities, and setting a reachable timer; modifying a control message frame format in combination with different interaction scenes, so the backward compatibility of a control message is ensured, and meanwhile, the additional overhead caused by adding an additional control message is avoided; based on multiple metric values and in combination with priority selection PPN, considering the network depth and the upstream link energy of the alternative father node, so the energy consumption of part of SN can be avoided, and the survival time of the whole network is effectively prolonged; and finally, enabling a part of CPNs to start a reachable timer after receiving the DAO, and considering the condition of forwarding the DAO or DAO-ACK loss, so the link construction failure caused by the loss of the control message is effectively avoided, and the transmission efficiency can be improved.
