Abstract
A communication system and method are disclosed for transmitting packets of information in at least one first format over a communications link that utilizes packets of information in a second format. In certain embodiments, the packets of information in a first format are converted to packets of information in the second format prior to transmission via the communications link by packing and fragmenting the information in the first format in a coordinated manner. Embodiments may also utilize packing subheaders and fragmentation control bits in the packing and fragmentation processes.
Claims36
A system for a subscriber unit which maps data bursts to an uplink frame and transmits the mapped data bursts over a communication link, the system comprising:
- a first module configured to receive service data units (SDUs) and classify the SDUs in a plurality of queues based upon SDU characteristics, each queue for serving a service-specific connection established at the subscriber unit;
- and
- a second module adapted to determine the length of a protocol data unit (PDU) for each connection based on one or more communication parameters characterizing the traffic on the respective connection, and to map the SDUs received from the respective queue into the respective PDU.
A method for mapping data bursts to uplink frames and transmitting the frames over a communication link from one or more subscriber units to a base station, comprising, at a subscriber unit:
- classifying service data units (SDUs) in a plurality of queues based upon SDU characteristics, each queue for serving a service-specific connection;
- determining the length of a protocol data unit (PDU) for each connection based on one or more communication parameters characterizing the traffic on the respective connection;
- and
- mapping the SDUs received from the respective queue into the respective protocol data units (PDUs).
