Configuration parameter update method and apparatus

A configuration parameter update method, comprising:

• receiving, by a second device, a first monitoring request sent by a first device, wherein
• the first monitoring request requests the second device to monitor a target event,
• the target event comprises one or more of a service change event, a service volume impact event, and a service volume change event,
• the service volume change event is an event in which a service volume is greater than a first threshold or less than a second threshold, and
• the first threshold is greater than the second threshold;
• monitoring, by the second device and in response to the first monitoring request, the target event;
• and
• after monitoring the target event, reporting, by the second device, first information of the target event to the first device to enable the first device to update a proximity communication (PC5) configuration parameter based on the first information, and to enable a plurality of terminals to perform communication with each other over PC5 using the updated PC5 configuration parameter,
• wherein the first information comprises one or more of service change information, service volume impact information, and service volume change information.

A configuration parameter update apparatus, comprising:

• a transceiver;
• and
• one or more processors connected to the transceiver, and configured to:
• cause the transceiver to send, a first monitoring request to a second device to request the second device to monitor a target event, wherein
• the target event comprises one or more of a service change event, a service volume impact event, and a service volume change event,
• the service volume change event is an event in which a service volume is greater than a first threshold or less than a second threshold, and
• the first threshold is greater than the second threshold;
• and
• in response to receiving through the transceiver, first information of the target event from the second device, wherein the first information comprises one or more of service change information, service volume impact information, and service volume change information,
• update a proximity communication (PC5) configuration parameter based on the first information to enable a plurality of terminals to perform communication with each other over PC5 using the updated PC5 configuration parameter.
