Apparatuses and methods for handling data packets

A method for assigning a value representing a length of a data packet to a field, the method comprising:

• determining a size of the data packet;
• setting a size of the field based on the determined size of the data packet;
• comparing the determined size of the data packet against a value threshold;
• calculating a value representing the length of the data packet based on said comparison and based on the determined size of the data packet;
• and
• assigning the calculated value representing the length of the data packet to the field, wherein,
• a) if the determined size of the data packet is below or equal to a first value threshold:
• calculating the value representing the length of the data packet to be an actual value of the determined size of the data packet;
• and
• b) if the determined size of the data packet is above said first value threshold calculating the value representing the length of the data packet based on the determined size of the data packet, wherein, calculating the value representing the length of the data packet comprises:
• determining an offset value based on the determined size of the data packet;
• and subtracting the offset value from an actual value of said determined size of the data packet.

An apparatus, comprising:

• a processing circuitry;
• and
• a memory circuitry storing computer program code which, when run in the processing circuitry, causes the apparatus to assign a value representing a length of a data packet to a field, wherein the computer program code, when run in the processing circuitry, causes the apparatus to:
• determine a size of the data packet;
• set a size of the field based on the determined size of the data packet;
• compare the determined size of the data packet against a value threshold;
• calculate a value representing the length of the data packet based on the determined size of the data packet;
• and
• assign the calculated value representing the length of the data packet to the field, wherein the memory circuitry storing computer program code which, when run in the processing circuitry, causes the apparatus to:
• if the determined size of the data packet is below or equal to a first value threshold:
• calculate the value representing the length of the data packet to be an actual value of the determined size of the data packet;
• and
• assign the calculated value representing the length of the data packet to the field, else
• if the determined size of the data packet is above said first value threshold:
• calculate the value representing the length of the data packet based on the determined size of the data packet;
• and
• assign the calculated value to the field, wherein the memory circuitry storing computer program code which, when run in the processing circuitry, causes the apparatus to calculate the value representing the length of the data packet by:
• determine an offset value based on the determined size of the data packet;
• and
• subtract the offset value from an actual value of said determined size of the data packet.

A method for handling a data packet, wherein a field is assigned a value representing a length of said data packet, the method comprising:

• obtaining the value representing the length of said data packet;
• determining a size of the field;
• and
• establishing an actual size of said data packet based on the determined size of the field and the obtained value representing the length of said data packet,
• wherein:
• if the determined size of the field is equal to a first size:
• establishing the actual size of the data packet to be the value assigned to the field;
• else
• if the determined size of the field is equal to a second size, which is different from the first size:
• establishing the actual size of said data packet based on the determined size of the field and the obtained value representing the length of said data packet,
• wherein establishing the actual size of said data packet comprising:
• determining an offset value based on the determined size of the field;
• and
• adding the determined offset value to the obtained value representing the length of said data packet.
