Method of providing circuit switched (SC) service using high-speed downlink packet access (HSDPA) or high-speed uplink packet access (HSUPA)
First Claim
1. A method for providing data in wireless communication system that supports High Speed Packet Access (HSPA), the method comprising:
- receiving at least one service data unit (SDU) from an upper layer;
adding a header, in a packet data convergence protocol (PDCP) layer, to the at least one received service data unit (SDU) to generate a protocol data unit (PDU),wherein the header includes timing information; and
delivering the generated protocol data unit to a lower layer,wherein the timing information is used for a de-jittering queue on a receiver side,wherein the timing information is a value of a counter,wherein the value of the counter is set by a portion of a connection frame number (CFN) included in the header of the generated PDU,wherein the portion of the CFN is first to fifth List Significant Bits (LSBs) of the CFN, andwherein the data is circuit switched (CS) service data provided in a packet switched (PS) network.

Abstract
Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and an operation method of a Packet Data Convergence Protocol (PDCP) entity in a Universal Mobile Telecommunications System (UMTS), and more particularly, to an operation method of transmitting, by a transmitting side (transmitter), data blocks by including a Connection Frame Number (CFN) therein such that a receiving side (receiver) processes each of received data blocks by a reference time, as a method of providing a Circuit Switched (CS) service using a High Speed Downlink Packet Access (HSDPA) or High Speed Uplink Packet Access (HSUPA) technology.

4. A device of a wireless communication system that supports High Speed Packet Access (HSPA), the device comprising:
-
a memory; and a processor configured to; receive at least one service data unit (SDU) from an upper layer; add a header, in a packet data convergence protocol (PDCP) layer, to the at least one received service data unit (SDU) to generate a protocol data unit (PDU), wherein the header includes timing information; and deliver the generated protocol data unit to a lower layer, wherein the timing information is used for a de-jittering queue on a receiver side, wherein the timing information is a value of a counter, wherein the value of the counter is set by a portion of a connection frame number (CFN) included in the header of the generated PDU, wherein the portion of the CFN is first to fifth List Significant Bits (LSBs) of the CFN, and wherein the data is circuit switched (CS) service data provided in a packet switched (PS) network.
