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.

The application discloses a virtual environment-based object construction method, device and readable storage medium, and relates to the field of virtual environments. The method includes: displaying an environment interface; receiving a 3D model input operation, the 3D model input operation is used to input a target 3D model; receiving a position input operation; displaying a target object at a display position according to the 3D model input operation and the position input operation, the target The object is obtained by filling voxel blocks within the contour range of the target 3D model. By importing the target 3D model in the virtual environment and selecting the display position of the target object, the target object is generated by filling voxel blocks within the outline range of the target 3D model in the virtual environment, which avoids when the player manually constructs the target object, The inability to accurately control the structure of voxel blocks leads to the failure of object construction, and improves the efficiency of object construction and the accuracy of object construction.

Embodiments of the present invention disclose a communication method, a network device and a system for a multi-RAT network. The communication method includes: retaining, in the overlapping coverage area of a multi-RAT network, a service channel and a common broadcast control channel of a basic network, and notifying a non-basic network to deactivate all or part of the common broadcast control channels; receiving a service request initiated by a terminal via the basic network; notifying, when the basic network is incapable of bearing the service request, the non-basic network to allocate a service channel of the non-basic network for the terminal. The technical solutions provided in the embodiments of the present invention are applicable to network systems of multi-RAT networks having overlapping coverage.

The application discloses a virtual environment-based object construction method, device and readable storage medium, and relates to the field of virtual environments. The method includes: displaying an environment interface; receiving an area selection operation for the virtual environment, where the area selection operation is used to determine the construction area; receiving an image input operation, where the image input operation is used for inputting a style image; selecting according to the area The operation and image input operation display the target object in the construction area, and the target object is obtained by filling the voxel blocks of the color corresponding to the style picture in the construction area. By selecting the construction area and inputting the picture in the virtual environment, filling the voxel blocks in the construction area in the virtual environment to generate a target object, and the target object is obtained by filling the voxel blocks of the corresponding color of the style picture in the construction area, Avoid the problem that the object construction fails due to the inability to accurately control the color of the voxel block, and improve the accuracy of object construction.

Disclosed is an RIM message updating method, comprising: a management node receives and stores RIM messages sent by at least two control nodes; and when the management node judges that object information in at least two stored RIM messages is inconsistent, the control nodes storing the RIM messages acquire the updated RIM messages according to a preset processing solution, the RIM messages stored by the control nodes comprising the object information. Also disclosed is an RIM message updating apparatus. A control node is enabled to update an RIM message in time, thereby avoiding radio service establishment failure caused by inconsistency of RIM messages of a serving node and the control node.
