Problems solved by technology
However, this method scans based on a fixed scanning period. In the case that different communication satellites cover different areas and the number of users in different areas is different, scanning based on the same scanning period is not conducive to improving the communication efficiency of terminal equipment. , and scanning the area where there is no terminal equipment through a fixed beam scanning cycle will also cause a waste of resources

Embodiment Construction
[0053] An embodiment of the present application provides a method for random access, a first communication device, and a second communication device, wherein the method and the device are based on the same technical concept, and since the method and the device have similar problem-solving principles, the device and the The implementation of the methods can be referred to each other, and repeated descriptions will not be repeated. In the description of the embodiments of the present application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B exist simultaneously, and There are three cases of B. The characters "three kinds generally indicate that the related objects before and after are a kind of "or" relationship. At least one involved in this application refers to one or more; multiple refers to two or more than two. In addition, w...

The invention discloses a method for random access and a communication device, and relates to the technical field of communication. A second communication device determines the corresponding relationship between the scanning periods of different scanning areas in the coverage range of the SSB beam and the RO, and then sends a first message including the information of the corresponding relationship through broadcasting; a first communication device receives the first message, determines the RO according to the scanning area where the first communication device is located and the first message, and initiates random access. In the application, since the different scanning areas are scanned by adopting the incompletely same scanning periods, the capacity of users in a communication system (satellite communication system) in which the second communication device is located can be improved, and the communication efficiency of the first communication device can also be improved; and the situation of resource waste caused by scanning different scanning areas by adopting a fixed scanning period is also avoided.
Description
technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and a communication device for random access. Background technique [0002] When natural disasters (earthquakes, mudslides, etc.) occur, the communication facilities (base stations, access network equipment and other network equipment) constructed on the ground are vulnerable to damage. When the communication facilities are damaged, users cannot transmit data through terminal equipment . However, the satellite is less affected by the geographical environment. When a natural disaster occurs, the terminal equipment can still transmit data through satellite communication. In addition, in some areas that are not conducive to the establishment of ground base stations, such as oceans, deserts, mountains and other areas, the terminal equipment can also be used. Get good communication efficiency by satellite. [0003] In related techno...
