Abstract

A method for operating an RLC entity and a MAC entity in a Universal Mobile Telecommunications System (UMTS), the European IMT-2000 system. A format of a MAC-hs PDU is optimized in a MAC-hs entity, so that a large number of users can be supported with using less resources when a VoIP service is provided in one cell.

Claims

1. A method of processing data units in a mobile communications system, the method comprising:

receiving a first data unit and a second data unit from an upper entity, wherein the first data unit includes a first header and a first payload and the second data unit includes a second header and a second payload;

converting at least one header field of the first header and at least one header field of the second header into at least one header field of a third data unit, wherein the third data unit includes at least one converted header field, the first payload, and the second payload; and

transferring the third data unit to a lower layer.

2. The method of claim 1, wherein the first data unit and the second data unit are MAC-hs Service Data Units (SDUs).

3. The method of claim 1, wherein the third data unit is a MAC-hs Protocol Data Unit (PDU).

4. The method of claim 1, wherein the lower layer is a physical layer.

5. The method of claim 1, wherein each header field of the first, second, and third header is same type if each header field of the first, second and third header is received via a single channel.

6. The method of claim 1, wherein each header field of first, second, and third header includes at least one of a C/T (Control/Traffic) field and a SN(Sequence Number) field.

7. The method of claim 1, wherein the converted header field of the third data unit is equal to at least one of header fields of the first header and the second header.

8. The method of claim 1, wherein the converted header field of the third data unit is not equal to both header fields of the first header and the second header.

9. A method of processing data units in a mobile communications system, the method comprising:

receiving a first data unit including a first header and a first payload from a lower layer;

wherein a second payload of a second data unit and a third payload of a third data unit are included in the received the first payload;

converting at least one header field of the first header into at least one header field of each header of the second data unit and the third data unit thereby generating a second header and a third header; and

transferring the second data unit and the third data unit to an upper layer, wherein the second data unit includes the second payload and the second header, and the third data unit includes the third payload and the third header.

10. The method of claim 9, wherein the first data unit is a MAC-hs Protocol Data Unit (PDU).

11. The method of claim 9, wherein the second data unit and the third data unit are MAC-hs Service Data Units (SDUs).

12. The method of claim 9, wherein the lower layer is a physical layer.

13. The method of claim 9, wherein each header field of first, second, and third header includes at least one of a C/T (Control/Traffic) field and a SN(Sequence Number) field.

14. The method of claim 9, wherein the header field of the first data unit is equal to at least one of header fields of the second header and the third header.

15. The method of claim 9, wherein the header field of the first data unit is not equal to both header fields of the second header and the third header.
