Abstract
Data packets transmitted over a wireless network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the subscriber station and the base station. An extended header element is added to a data packet that is to be transmitted over the wireless network. The extended header element contains an index that is used along with an identifier to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.
Claims21
An medium access control (MAC) for suppressing a first byte of a data packet header contained in a data packet, comprising:
- a header parser configured to retrieve an index from an extended header element contained in the data packet header, the index identifying a data mask, the data mask being used to determine which bytes of the data packet header are to be suppressed;
- and
- a control unit configured to suppress the first byte of the data packet header based upon on the data mask.
A method for suppressing a first byte of a data packet header contained in a data packet, comprising:
- (a) retrieving an index from an extended header element contained in the data packet header, the index identifying a data mask, the data mask being used to determine which bytes of the data packet header are to be suppressed;
- and
- (b) suppressing the first byte of the data packet header based upon on the data mask.
