1. A method of processing data units in a mobile communications system, the method comprising:
- receiving, from an upper entity, a first data unit including a first header and a first payload, and a second data unit including a second header and a second payload;
converting a header field of the first header and a header field of the second header into a header field of a third header of a third data unit including the first payload and the second payload;
determining a format of the third data unit by an upper entity signaling; and
transferring the third data unit to a lower layer,wherein the header field of the first header and the header field of the second header are not fixed in size,wherein the first data unit and the second data unit are Medium Access Control-high speed Service Data Units (MAC-hs SDUs) and the third data unit is a MAC-hs Protocol Data Unit (PDU),wherein the third data unit corresponds to a queue used for a Voice over Internet Protocol (VoIP) service,wherein a Size Index Identifier (SID) field of the third data unit is set to have a length of 4 bits or 5 bits in the queue used for the VoIP service,wherein a queue identifier (queue ID) and a Number (N) field are not included in the third data unit, andwherein a number of bits of a Transmission Sequence Number (TSN) of the third data unit is set to have a length of less than 5 bits.

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.

7. A method of processing data units in a mobile communications system, the method comprising:
-
receiving, from a lower layer, a first data unit including a first header and a first payload including a second payload of a second data unit and a third payload of a third data unit; converting a header field of the first header into a header field of a second header of the second data unit and a header field of a third header of the third data unit; and transferring the second data unit and the third data unit to an upper layer, wherein an upper entity signaling of a transmitting side determines a format of the first data unit, and wherein the header field of the second header and the header field of the third header are not fixed in size, wherein the first data unit is a Medium Access Control-high speed Protocol Data Unit (MAC-hs PDU), and the second data unit and the third data unit are MAC-hs Service Data Units (SDUs), wherein the first data unit corresponds to a queue used for a Voice over Internet Protocol (VoIP) service, wherein a Size Index Identifier (SID) field of the first data unit is set to have a length of 4 bits or 5 bits in the queue used for the VoIP service, wherein a queue identifier (queue ID) and a Number (N) field are not included in the first data unit, and wherein a number of bits of a Transmission Sequence Number (TSN) of the first data unit is set to have a length of less than 5 bits. - View Dependent Claims (8, 9, 10, 11)
