The invention provides an information indicating method, an information using method, a related device and a related system, which can be applied to a cooperative intelligent transportation system and the like. The method comprises: a first device generating and sending a first message, capability information being used for indicating a message type set, the message type set comprising one or more message types supported by the first device; the second device receiving the first message may send a second message to the first device according to the capability information, the second message belonging to a set of message types supported by the first device. Since the first device can support the message type to which the second message belongs, the first device can respond to the second message sent by the second device. Therefore, the problem that the capabilities of the cooperation initiator and the cooperation receiver are not matched can be solved, unnecessary resource consumption caused by the fact that the cooperation initiator sends an invalid request is avoided, and improvement of interaction efficiency, passing efficiency and safety of cooperation between devices is facilitated.

    提供了一种信息指示方法、信息使用方法及相关装置、系统,可应用于合作式智能运输系统等。该方法包括:第一设备生成并发送第一消息,其中的能力信息用于指示消息类型集合,该消息类型集合包括第一设备支持的一种或多种消息类型;接收到第一消息的第二设备可以根据能力信息,向第一设备发送第二消息,该第二消息属于第一设备支持的消息类型集合。由于第一设备能够支持第二消息所属的消息类型,故能够对第二设备发送的第二消息做出响应。从而可以解决协作发起方和协作接收方能力不匹配的问题,避免协作发起方发送无效请求带来不必要的资源消耗,且有利于提升设备间协作的交互效率、通行效率和安全性。
