Abstract
A method for managing received data by a radio link protocol layer for interfacing data between a radio communication terminal and a data processing terminal of a complex digital cellular terminal. Data of a newly received frame is stored in a ring-type frame content buffer in reception order, and the stored frame is managed by a frame control table. If the newly stored frame and a previously stored frame have not successive frame numbers, the newly stored frame is registered in a negative acknowledge control table.
Claims7
A method for managing received data by a radio link protocol layer for interfacing the received data between a radio communication terminal and a data processing terminal of a complex digital cellular terminal, said method comprising the steps of:
- storing data of a newly received frame in a frame content buffer in reception order irrespective of a frame number associated with said newly received frame and managing the stored frame by a frame control table;
- and
- registering the newly stored frame in a negative acknowledge control table, when the newly stored frame and a previously stored frame do not have successive frame numbers,
- wherein registered in said frame control table is a start address of said frame content buffer, an end address of said frame content buffer, a sequence number, and one of a valid and invalid flag.
A method for managing received data by a radio link protocol layer for interfacing the received data between a radio communication terminal and a data processing terminal of a complex digital cellular terminal, said method comprising the steps of:
- sequentially storing data of a newly received frame in a frame content buffer;
- transmitting a valid control frame when the newly received frame and a previously received frame have successive frame sequence numbers;
- registering the newly received frame in a negative acknowledge control table and transmitting a negative acknowledge control frame when the newly received frame and the previously received frame do not have successive frame sequence numbers, and the newly received frame is a frame which is not managed by said negative acknowledge control table;
- deleting a previously registered frame from said negative acknowledge control table and transmitting said valid control frame when the newly received frame and the previously received frame do not have successive frame sequence numbers and the newly received frame is a frame managed by said negative acknowledge control table;
- and
- registering the received frame in a frame control table.
An apparatus for managing received data by a radio link protocol layer for interfacing the received data between a radio communication terminal and a data processing terminal of a complex digital cellular terminal, said apparatus comprising:
- means for storing data of a newly received frame in a frame content buffer in reception order irrespective of a frame sequence number associated with said newly received frame;
- means for managing the stored frame using a frame control table;
- and
- means for registering the newly stored frame in a negative acknowledge control table,
- wherein registered in said frame control table is a start address of said frame content buffer, an end address of said frame content buffer, a sequence number, and one of a valid and invalid flag.
