Method for providing an object message and message generation device

A method for providing an object message including selected information about a surrounding region of a participant in a communication network, the method comprising the following steps:

• acquiring the selected information about the surrounding region, including perceived objects and/or perceived regions, wherein the selected information are segmented into at least a first message item and a second message item;
• (i) receiving a maximum data rate for transmitting the object message from a communication management entity or (ii) estimating the maximum data rate for transmitting the object message;
• determining an optimized data size and an optimized message generation period of the object message by carrying out the following steps:
• determining a first relevancy weight for the first message item, depending on a content of the first message item, and determining a second relevancy weight for the second message item, depending on a content of the second message item,
• defining an optimization function, at least depending on:
• the first relevancy weight and a generation period of the first message item, and
• the second relevancy weight and a generation period of the second message item, and
• optimizing the optimization function taking into account that the optimized data size divided by the optimized message generation period is less than or equal to the maximum data rate, to determine the optimized message generation period and optimized data size of the object message, and
• providing the object message with the optimized message generation period and the optimized data size to be sent via the communication network.

A message generation device, comprising:

• a communication module configured to:
• receive information about a surrounding region,
• acquire selected information about the surrounding region, including perceived objects and/or perceived regions, wherein the selected information are segmented into at least a first message item and a second message item,
• transmit the selected information about the surrounding region, including the first and second message items, to an evaluation unit;
• an ancilla module configured to receive or estimate a maximum data rate from a communication management entity, and
• the evaluation unit configured to:
• determine a first relevancy weight of the first message item depending on a content of the first message item, and determine a second relevancy weight of the second message item, depending on a content of the second message item,
• define an optimization function, at least depending on the first relevancy weight and a generation period of the first message item, and the second relevancy weight and a generation period of the second message item,
• optimize the optimization function taking into account that an optimized data size divided by an optimized message generation period is less than or equal to the maximum data rate, to determine an optimized generation period and optimized data size of an object message,
• provide the object message with the optimized message generation period and the optimized data size to be sent via the communication network.

A participant, comprising:

• a message generation device, including:
• a communication module configured to:
• receive information about a surrounding region,
• acquire selected information about the surrounding region, including perceived objects and/or perceived regions, wherein the selected information are segmented into at least a first message item and a second message item,
• transmit the selected information about the surrounding region, including the first and second message items, to an evaluation unit;
• an ancilla module configured to receive or estimate a maximum data rate from a communication management entity, and
• the evaluation unit configured to:
• determine a first relevancy weight of the first message item depending on a content of the first message item, and determine a second relevancy weight of the second message item, depending on a content of the second message item,
• define an optimization function, at least depending on the first relevancy weight and a generation period of the first message item, and the second relevancy weight and a generation period of the second message item,
• optimize the optimization function taking into account that an optimized data size divided by an optimized message generation period is less than or equal to the maximum data rate, to determine an optimized generation period and optimized data size of an object message,
• provide the object message with the optimized message generation period and the optimized data size to be sent via the communication network.

A non-transitory computer-readable data carrier on which is stored a computer program for providing an object message including selected information about a surrounding region of a participant in a communication network, the computer program, when executed by a computer, causing the computer to perform the following steps:

• acquiring the selected information about the surrounding region, including perceived objects and/or perceived regions, wherein the selected information are segmented into at least a first message item and a second message item;
• (i) receiving a maximum data rate for transmitting the object message from a communication management entity or (ii) estimating the maximum data rate for transmitting the object message;
• determining an optimized data size and an optimized message generation period of the object message by carrying out the following steps:
• determining a first relevancy weight for the first message item, depending on a content of the first message item, and determining a second relevancy weight for the second message item, depending on a content of the second message item,
• defining an optimization function, at least depending on:
• the first relevancy weight and a generation period of the first message item, and
• the second relevancy weight and a generation period of the second message item, and
• optimizing the optimization function taking into account that the optimized data size divided by the optimized message generation period is less than or equal to the maximum data rate, to determine the optimized message generation period and optimized data size of the object message, and
• providing the object message with the optimized message generation period and the optimized data size to be sent via the communication network.
