Description
본 발명은 알엘씨(RLC) 프로토콜의 이피씨(EPC) 제어 방법에 관한 것으로, 특히 WCDMA 프로토콜 중 라디오 링크제어(RLC : Radio Link Control) 계층에서 PDU 전송에러(missing PDU)가 발생했을 때, 이를 처리하기 위한 상태 PDU(status PDU)의 재전송 메커니즘인 EPC(Estimated PDU Counter)를 보다 효율적으로 수행할 수 있도록 하는 RLC 프로토콜의 EPC 제어 방법에 관한 것이다.The present invention relates to an EPC control method of the RLC protocol, and in particular, when a PDU transmission error occurs in the Radio Link Control (RLC) layer of the WCDMA protocol, The present invention relates to an EPC control method of an RLC protocol for more efficiently performing an EPC (Estimated PDU Counter), which is a retransmission mechanism of a status PDU (status PDU) for processing.
일반적으로, 프로토콜 데이터 단위(PDU : protocol data unit)는 특정 계층의 프로토콜 안에서 두 개의 실체간에 교환되는 세분화된 데이터 블록의 단위를 기술적인 이름으로 구분해 부르는 것으로, 많은 사람들이 "PDU"나 "프레임" 등으로 엄격하게 구분해 사용하지 않고, 네트웍을 통해 이동하는 모든 데이터 단위를 그저 "패킷"이라고 부르는 경우가 많다.In general, a protocol data unit (PDU) is a technical name for a unit of granular data block exchanged between two entities within a protocol of a specific layer, and many people refer to a "PDU" or "frame". Rather than being strictly separated by "," every data unit moving through the network is often called just a "packet."
그리고, EPC(Estimated PDU Counter)는 수신측에서 송신측으로 상태를 보고할 때, 손실된 PDU의 재전송을 스케줄링 하기 위해 사용되는 메커니즘으로, 손실된 PDU에 대해 재전송을 요구하고 그 재전송 요구에 의해서도 받지 못한 PDU들에 대한 새로운 상태 보고를 하게 된다.In addition, an EPC (Estimated PDU Counter) is a mechanism used to schedule retransmission of a lost PDU when reporting a status from a receiving side to a transmitting side. There is a new status report for the PDUs.
이때, 상기 상태보고는 상태 PDU(STATUS PDU)에 의해 이루어지는데, 두 상태보고 사이의 시간은 "Timer_EPC"와 "VR(EP)"에 의해 제어된다.At this time, the status report is made by a status PDU, and the time between the two status reports is controlled by "Timer_EPC" and "VR (EP)".
여기서, 상기 "Timer_EPC"는 상태 PDU(STATUS PDU)를 보낸 후, 첫 번째로 재전송 되는 AMD PDU의 수신에 소요되는 왕복시간(round-trip delay)으로서, 상위계층에 의해 정해진다.Here, the "Timer_EPC" is a round-trip delay for receiving the first AMD PDU retransmitted after sending a status PDU, which is determined by a higher layer.
또한, 상기 "VR(EP)"은 가장 최근의 상태보고 시 요구한 재전송 요구 PDU의 개수로 초기화되어, 각 TTI(Transmission time interval, 데이터 전송의 시간 단위)동안 받은 PDU의 개수만큼 감소되고, "VR(EP)"이 0이 되면 가장 최근의 상태보고가 재전송 요구한 모든 PDU를 받았는지 체크하여, 요구했던 PDU를 다 받지 못했다면 새로운 상태 PDU를 보내 재전송을 요구하게 된다.In addition, the "VR (EP)" is initialized to the number of retransmission request PDUs required for the most recent status report, and is reduced by the number of PDUs received during each TTI (Transmission time interval, time unit of data transmission). When VR (EP) "is 0, the most recent status report checks whether all PDUs requested for retransmission have been received, and if a requested PDU is not received, a new status PDU is sent to request retransmission.
상기와 같이 RLC에서는 받지 못한 PDU 재전송을 우선적으로 처리 해주어야 하므로, 수신측에서 송신측으로 상태 PDU(STATUS PDU)를 빨리 보내주는 것이 중요하다.As described above, the RLC must first process the PDU retransmission that has not been received. Therefore, it is important to quickly send a status PDU from the receiving side to the transmitting side.
그런데, 종래에는 상기와 같이 VR(EP)값이 0이 되었을 때, PDU의 수신여부를 검증한 후 상태 PDU(STATUS PDU)를 보내기 때문에, 시간적으로 많은 부하가 걸리게 되는 문제점이 있다.However, in the related art, when the VR (EP) value becomes 0 as described above, since a status PDU is sent after verifying whether or not the PDU is received, a large load is caused in time.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출한 것으로, WCDMA 프로토콜 중 라디오 링크제어(RLC : Radio Link Control) 계층에서 PDU 전송에러(missing PDU)가 발생했을 때, 이를 처리하기 위한 상태 PDU(status PDU)의 재전송 메커니즘인 EPC(Estimated PDU Counter)를 보다 효율적으로 수행할 수 있도록 하는 RLC 프로토콜의 EPC 제어 방법을 제공함에 그 목적이 있다. Accordingly, the present invention was created to solve the above-mentioned conventional problems. When the PDU transmission error (missing PDU) occurs in the Radio Link Control (RLC) layer of the WCDMA protocol, An object of the present invention is to provide an EPC control method of an RLC protocol that can efficiently perform an EPC (Estimated PDU Counter), which is a retransmission mechanism of a status PDU.
이와 같은 목적을 달성하기 위한 본 발명은, 이동통신 시스템에 있어서, 이동통신 시스템에 있어서, 송신측으로부터 수신한 데이터(PDU : Protocol Data Unit)에서 손실된 데이터를 확인하여 그 손실된 데이터에 대한 재전송을 요구할 경우, 수신측은 재전송 받을 데이터의 개수에 해당하는 만큼의 설정 시간(Timer EPC)이 지난 후, 그 재전송 받은 데이터에 대한 손실 유무에 관계없이 그 시점의 상태 데이터(STATUS PDU)를 송신측으로 전송하고, 송신측은 상기 상태 데이터로 부터 재전송되었던 데이터의 손실 유무를 판별하여 손실된 데이터를 재전송하고, 수신측은 상기 상태 데이터 전송 후, 즉시 수신된 모든 데이터를 상위 계층으로 전달하여, 손실된 데이터의 재전송 처리에 소요되는 시간을 절감하도록 이루어진 것을 특징으로 한다.The present invention for achieving the above object is, in the mobile communication system, in the mobile communication system, to confirm the data lost in the data (PDU: Protocol Data Unit) received from the transmitting side and retransmitted for the lost data When the request is made, the receiver sends the status data (STATUS PDU) at that time regardless of the loss of the retransmitted data after a set time (Timer EPC) corresponding to the number of data to be retransmitted. The transmitter determines whether there is any loss of data retransmitted from the state data and retransmits the lost data.The receiver transmits all received data immediately to the upper layer after the state data is transmitted, and retransmits the lost data. Characterized in that it is made to reduce the time required for processing.
본 발명은 "VR(EP)"값이 0이 되었을 때, 재전송 요구했던 PDU 들을 다 받았는지 검사하여 상태 PDU(STATUS PDU)를 보낼지 여부를 판단하는 과정을 거치지 않고, 새로운 상태 PDU(STATUS PDU)를 무조건 송신측으로 보내 송신측에서 재전송 여부를 판단하게 하는 특징이 있다.When the value of the "VR (EP)" is 0, the present invention does not go through a process of determining whether to send a status PDU by checking whether all PDUs requested for retransmission are received, and a new status PDU (STATUS PDU). Is sent to the sender unconditionally to determine whether to send again.
즉, 본 발명은 요구했던 PDU 들을 다 받지 않은 상황이라면 좋은 경우이고, 그렇지 않은 경우라 할지라도 NO_MORE SUFI(Super Field)만 포함하는 상태 PDU(STATUS PDU)를 보내는 것이, 고속의 데이터를 처리하는데 보다 효율적으로 작용하게 되는 것이다.That is, the present invention is a good case if the situation does not receive all the requested PDUs, even if not, sending a status PDU (STATUS PDU) containing only NO_MORE SUFI (Super Field), it is more than processing a high-speed data It will work efficiently.
여기서, 상기 "NO_MORE SUFI"는 상태 PDU의 데이터 필드 항목 중 하나로서, 더 이상의 재 전송할 데이터가 없다(no more data)는 것을 의미한다.Here, "NO_MORE SUFI" is one of data field items of the status PDU, and means that there is no more data to be resent (no more data).
이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.
도1은 본 발명에 의한 RLC 프로토콜의 EPC 제어 과정을 보인 상태도로서, 하나의 TTI당 하나의 PDU를 받고 윈도우 사이즈는 5라고 가정한다.1 is a state diagram illustrating an EPC control process of an RLC protocol according to the present invention. It is assumed that one PDU is received per TTI and the window size is 5.
상기에서 윈도우 사이즈가 5라고 했으므로 송신측 라디오 링크 컨트롤(RLC)2에서, 5개의 PDU(PDU#1 ~ PDU#5)를 수신측 라디오 링크 컨트롤(RLC)1로 보내게 되는데, 그 과정에서 4개의 PDU(PDU#1 ~ PDU#4)가 손실(LOST)되고 마지막 1개의 PDU(PDU#5)만 정상적으로 수신될 경우, RLC1에서는 손실된 4개의 PDU에 대한 정보를 포함하는 상태 PDU(STATUS PDU)를 스케줄링하여 송신측으로 보내게 된다.Since the window size is 5, the transmitting radio link control (RLC) 2 sends five PDUs (PDU # 1 to PDU # 5) to the receiving radio link control (RLC) 1. Lost LOST PDUs (PDU # 1 to PDU # 4) and only the last PDU (PDU # 5) is successfully received, the RLC1 contains a status PDU containing information about the four lost PDUs. ) Is scheduled and sent to the sender.
이와 아울러, RLC1의 "VR(EP)=4"가 설정되고 "Timer EPC" 동안 재전송 요구한 PDU 하나씩을 수신하게 된다. In addition, "VR (EP) = 4" of RLC1 is set, and one PDU requested for retransmission is received during "Timer EPC".
본 실시예에서는 "PDU#1"을 먼저 재전송 받은 후 "VR(EP)=3"으로 설정되고, "Timer EPC" 동안 "PDU#2"를 재전송 받은 후 "VR(EP)=2"가 된다. 그리고, 이후 2 TTI 동안 즉, "VR(EP)=0"이 될 동안 "PDU#3, PDU#4"를 받지 못하였다.In the present embodiment, after "PDU # 1" is retransmitted first, "VR (EP) = 3" is set, and after "PDU # 2" is retransmitted during "Timer EPC", it becomes "VR (EP) = 2". . Then, during 2 TTIs, that is, while "VR (EP) = 0", "PDU # 3 and PDU # 4" were not received.
이 경우, 종래에는 상태 PDU(STATUS PDU)를 보낼지 여부를 결정하기 위해 즉, PDU의 재전송을 요구할 것인지 여부를 결정하기 위해 PDU의 수신여부를 검증하기 때문에 시간적으로 많은 부하가 걸리게 되는데, 본 발명에서는 PDU의 수신여부를 검증하지 않고 그 시점의 상태 PDU를 바로 송신측으로 전송하여, 송신측에서 그 상태 PDU를 보고 재전송 할 것인지 여부를 판단하도록 함으로써, 수신측에서 상태 PDU 송신 여부를 결정하기 위해 소요되는 시간을 제거하여, 그만큼 처리속도를 향상시키게 된다.In this case, conventionally, since the reception of the PDU is verified in order to determine whether to send a status PDU, that is, whether to request retransmission of the PDU, it takes a lot of time in the present invention. It is necessary to determine whether to send the status PDU by sending the status PDU at that time to the sender without verifying whether the PDU has been received and determining whether or not to retransmit by viewing the status PDU. By eliminating time, the processing speed is increased accordingly.
다시 말해, 만약 재전송 요구한 PDU를 모두 수신하게 되면, 종래의 경우 PDU 수신여부 검증 과정을 통해 상태 PDU를 보내지 않게 되지만, 본 발명에서는 그러한 검증 과정 없이 재전송 할 데이터가 없음을 나타내는 상태 PDU를 무조건 송신하게 된다.In other words, if all of the PDUs requesting retransmission are received, the conventional state does not send a status PDU through the PDU reception verification process, but the present invention unconditionally transmits a status PDU indicating that there is no data to be retransmitted without such verification process. Done.
따라서, 다시 재전송 PDU를 요구할 경우 종래의 방법에 비해서 본 발명에 의한 방법이 보다 빨리 재전송을 요구하여 받게 되는 효과가 있다.Therefore, when the retransmission PDU is requested again, the method according to the present invention has the effect of requesting and retransmitting faster than the conventional method.
이에 따라, 상기 도1에서 상태 PDU를 송신측으로 보낸 후 "VR(EP)=2"로 설정되고, "Timer EPC" 동안 "PDU#3"를 재전송 받은 후 "VR(EP)=1"이 되고, 다시 "Timer EPC" 동안 "PDU#4"를 재전송 받은 후 "VR(EP)=0"이 되고, 상술한 바와 같이 PDU 수신여부 검증 과정을 거치지 않고 재전송 할 데이터가 없음을 나타내는 상태 PDU를 무조건 송신하게 된다.Accordingly, after the status PDU is sent to the transmitter in FIG. 1, "VR (EP) = 2" is set, and after "PDU # 3" is retransmitted during "Timer EPC", "VR (EP) = 1" is obtained. After re-transmitting "PDU # 4" during "Timer EPC", it becomes "VR (EP) = 0" and unconditionally indicates the status PDU indicating that there is no data to be retransmitted without going through PDU reception verification process as described above. Will be sent.
즉, 종래의 경우에는 상기와 같이 재전송 요구한 PDU를 모두 수신하게 되면, 상태 PDU를 보낼지 여부를 결정하기 위한 PDU 수신여부 검증 과정을 거치게 되지만, 본 발명에서는 그러한 검증 과정을 거치지 않음으로써 시간 손실을 방지하는 효과가 있다.That is, in the conventional case, when all of the PDUs requested for retransmission are received as described above, the PDU is received or not for verifying whether to send the status PDU. However, in the present invention, time loss is avoided by not performing such a verification process. It is effective to prevent.
참고로, 상기 도1에서 송신측에서 전송할 PDU는 그 상위인 패킷데이터 집중 프로토콜(PDCP : Packet Data Convergence Protocol) 2에서 프리미티브(RLC_AM_DATA_REQ)를 통해 RLC2로 전달되는 전처리 과정을 거치고, 수신측에서는 프리미티브(CRLC_CONFIG_REQ)를 통해 "Timer EPC" 등의 RLC1 개체에 대한 환경조건을 설정하는 전처리 과정을 거치고, 재전송 과정을 거쳐 모든 PDU를 수신한 RLC1은 프리미티브(RLC_AM_DATA_IND)를 통해 상위 계층(PDCP1)으로 전달하게 된다.For reference, in FIG. 1, the PDU to be transmitted by the transmitting side undergoes a preprocessing process that is transmitted to RLC2 through the primitive (RLC_AM_DATA_REQ) in the Packet Data Convergence Protocol (PDCP) 2 that is higher, and the primitive CRC_CONFIG_REQ on the receiving side. RLC1 receives all PDUs through the retransmission process to the upper layer (PDCP1) through the primitive (RLC_AM_DATA_IND).
이상에서 설명한 바와 같이 본 발명 RLC 프로토콜의 EPC 제어 방법은, WCDMA 프로토콜 중 라디오 링크제어(RLC : Radio Link Control) 계층에서 PDU 전송에러(missing PDU)가 발생했을 때, 이를 처리하기 위한 상태 PDU(status PDU)의 재전송 메커니즘인 EPC(Estimated PDU Counter)의 효율성을 향상시키는 효과가 있다.As described above, the EPC control method of the RLC protocol of the present invention includes a status PDU (status) for processing a PDU transmission error (missing PDU) in the Radio Link Control (RLC) layer of the WCDMA protocol. There is an effect of improving the efficiency of the EPC (Estimated PDU Counter) which is a retransmission mechanism of the PDU.
도 1은 본 발명에 의한 RLC 프로토콜의 EPC 제어 과정을 보인 상태도.1 is a state diagram showing an EPC control process of the RLC protocol according to the present invention.
