Method and apparatus for controlling loads on networks
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of controlling a network, for example a peer-to-peer network, comprising a set of user equipment, UE, devices, including a first UE, is described. The method comprises determining, for example by the first UE, a first channel load metric, for example a channel busy ratio, CBR, of a set of channel load metrics of a first channel of a set of channels of the network; generating, by the first UE, a first message, for example a V2X message, of a set of messages according to the determined first channel load metric; and transmitting, by the first UE, the generated first message, optionally on the first channel. A network and a UE are also described.

wherein a time elapsed between two consecutive CPM generations is greater than or equal to a minimum threshold and less than or equal to a maximum threshold.
2. The method of claim 1 ,

4. The method of claim 1 ,

wherein the CPM is generated periodically, and
wherein a generation frequency of the CPM is determined by a dynamic behavior of a detected object status.
5. The method of claim 4 ,
wherein the dynamic behavior is associated with a change of a position of a detected object, a change of a speed of the detected object, and a change of a direction of the detected object.
6. The method of claim 1 ,
wherein the one or more objects further includes a third object selected based on a time associated with the third object.
7. A method performed by a second intelligent transport systems station (ITS-S), the method comprising:
receiving, from a first ITS-S, a collective perception message (CPM) including information on one or more objects selected from a plurality of perceived objects, and
identifying statuses of the one or more objects based on the CPM,
wherein the one or more objects include a first object selected based on a difference between a current speed of the first object and a previous speed of the first object previously included in a CPM exceeding a first threshold or a second object selected based on a distance between a current position of the second object and a previous position of the second object previously included in a CPM exceeding a second threshold, and

9. The method of claim 7 ,

14. The first ITS-S of claim 11 ,
wherein the CPM is generated periodically,
wherein a generation frequency of the CPM is determined by a dynamic behavior of a detected object status, and
wherein the dynamic behavior is associated with a change a position of a detected object, a change of a speed of the detected object, and a change of a direction of the detected object.
15. A second intelligent transport systems station (ITS-S) comprising:
a transceiver; and
a controller configured to:
receive, from a first ITS-S, a collective perception message (CPM) including information on one or more objects selected from a plurality of perceived objects, and
