Abstract
A method, node device, signal, and instruction set to reduce the size of data packets in a telecommunications network. The invention provides a solution wherein a size of SDU position identifiers in a header of a packet data unit is optimized depending on the actual size of the packet data unit, reducing the amount of data sent in the telecommunication network.
Claims14
A node arrangement in a communication network for optimizing a size of a header in a packet data unit (PDU), comprising:
- means for deriving from an actual size of the PDU a required size of a service data unit (SDU), position identifier;
- means for generating a PDU header with optimized SDU position identifier field size;
- means for sending in a header separate from the PDU header to a receiving node arrangement a control signal with information about the size of the PDU;
- and
- means for sending the PDU to a receiving node arrangement.
A method for optimizing a header size of packet data units (PDUs), in a telecommunications network, comprising the steps of:
- deriving from an actual size of the PDU a required size of a service data unit (SDU), position identifier field;
- generating a PDU header with optimized SDU position identifier size;
- sending to a receiving node a control signal, on a separate communication channel or in another header element, with information about the size of the PDU;
- sending the PDU to the receiving node;
- wherein the control signal comprise information about the SDU position identifier size.
A signal for transmitting a packet data unit (PDU), in a telecommunications network, comprising a header with dynamically adjustable SDU position identifier field size.
A receiving node in a wireless communication network, comprising
- means for receiving control signal information from a transmitting node arrangement with information about the size of a packet data unit (PDU), field, the PDU to be received in another message;
- means for deriving from the information about the size of the PDU the optimal size of the SDU position identifiers;
- means for receiving optimized packet data units from the transmitting node arrangement;
- means for decoding the received optimized PDU based on the derived size of the SDU position identifiers.
An instruction set in a node arrangement in a communications network, comprising instruction sets for:
- receiving payload data to send;
- deriving from an actual size of the PDU the required size of a service data unit (SDU), position identifier field;
- generating a PDU header with optimized SDU position identifier size;
- sending to a receiving node arrangement in a header separate from the PDU header a control signal with information about the size of the PDU;
- and
- sending the PDU to a receiving node.
