消息处理方法、装置以及系统Message processing method, device and system

技术领域technical field

本发明涉及通信领域，尤其涉及一种消息处理方法、装置以及系统。The present invention relates to the communication field, in particular to a message processing method, device and system.

背景技术Background technique

在LTE(Long Term Evolution，长期演进)系统中，UE(User Equipment，用户设备)使用RACH(Random Access Channel，随机接入信道)进行初始接入，或者获取同步，该过程称为RA(Random Access，随机接入)。根据UE使用的随机接入码的来源，随机接入过程分为两种模式：竞争模式和非竞争模式，当使用非竞争模式时，UE使用的初始接入前导码(Preamble)由网络分配，所以不存在竞争。网络发起非竞争模式RACH过程的场景包括：切换、下行数据到达但UE处在非同步状态等。In the LTE (Long Term Evolution, long-term evolution) system, UE (User Equipment, user equipment) uses RACH (Random Access Channel, Random Access Channel) for initial access, or to obtain synchronization, this process is called RA (Random Access , random access). According to the source of the random access code used by the UE, the random access process is divided into two modes: contention mode and non-competition mode. When using the non-competition mode, the initial access preamble (Preamble) used by the UE is allocated by the network. So there is no competition. Scenarios in which the network initiates the non-contention mode RACH process include: handover, arrival of downlink data but the UE is in an asynchronous state, etc.

当eNB(evolved NodeB，演进基站)从网关收到下行数据时，如果发现UE处在连接(CONNECTED)状态，但处于上行非同步状态，eNB触发非竞争模式RACH流程，该流程包括：When the eNB (evolved NodeB, evolved base station) receives downlink data from the gateway, if it finds that the UE is in the CONNECTED state but in the uplink asynchronous state, the eNB triggers the non-competition mode RACH process, which includes:

S100、eNB发送随机接入前导配置消息(Random Access PreambleAssignment)，该消息携带给UE分配的专用Preamble；S100. The eNB sends a Random Access Preamble Assignment message (Random Access PreambleAssignment), which carries a dedicated Preamble assigned to the UE;

S101、UE发送随机接入前导消息(Random Access Preamble)，该随机接入前导消息包含eNB分配的Preamble。S101. The UE sends a random access preamble message (Random Access Preamble), where the random access preamble message includes the Preamble allocated by the eNB.

S102、eNB发送随机接入响应消息(Random Access Response)，该随机接入响应消息携带TA(Time Alignment，时间调整)信息和UL GRANT(Uplink Grant，上行资源指示)。S102. The eNB sends a random access response message (Random Access Response), which carries TA (Time Alignment, time adjustment) information and UL GRANT (Uplink Grant, uplink resource indication).

在接收到eNB发送的随机接入响应消息后，UE使用UL GRANT指示的上行传输资源发送上行数据。After receiving the random access response message sent by the eNB, the UE uses the uplink transmission resources indicated by the UL GRANT to send uplink data.

其中，在S101中，UE在发出随机接入前导消息后，会根据发送该消息使用的PRACH(Physical Random Access Channel，物理随机接入信道)资源，计算等待时间窗(RA-window)，在RA-window内等待eNB发送的随机接入响应消息。如果在RA-window内没有接收到随机接入响应消息，则UE在下一个可用的PRACH资源上继续尝试随机接入，当进行第二次发起随机接入时，如果网络分配的专用Preamble尚未失效，UE就继续使用该Preamble。UE收到随机接入响应消息后，恢复同步状态，此后如果收到下行数据，向eNB发送确认(ACK)或非确认(NACK)信息，以推动eNB的发送窗口，或触发eNB重传数据。Among them, in S101, after the UE sends the random access preamble message, it will calculate the waiting time window (RA-window) according to the PRACH (Physical Random Access Channel, Physical Random Access Channel) resource used to send the message. -Waiting for the random access response message sent by the eNB within the window. If no random access response message is received within the RA-window, the UE will continue to try random access on the next available PRACH resource. When initiating random access for the second time, if the dedicated Preamble allocated by the network has not expired, The UE continues to use the Preamble. After receiving the random access response message, the UE restores the synchronization state. After that, if it receives downlink data, it sends an acknowledgment (ACK) or non-acknowledgement (NACK) message to the eNB to push the eNB's sending window or trigger the eNB to retransmit data.

上述流程中，随机接入响应消息本身不使用HARQ(Hybrid AutomaticRetransmission Request，混合自动重传请求)机制，eNB发出随机接入响应消息后，并不确定UE是否正确地接收到随机接入响应消息，即eNB发出随机接入响应消息后，就会发出下行数据，而如果UE没有正确收到随机接入响应消息，没有获得该消息中的时间调整指示信息，就不能针对收到的下行数据向eNB发送HARQ反馈，eNB没能收到UE发送的ACK，就会不断重传下行数据，直至达到最大重传次数，eNB丢弃该数据，降低了数据传输的消息，导致系统资源的浪费。In the above process, the random access response message itself does not use the HARQ (Hybrid Automatic Retransmission Request, hybrid automatic retransmission request) mechanism. After the eNB sends the random access response message, it is not sure whether the UE has correctly received the random access response message. That is, after the eNB sends the random access response message, it will send downlink data, and if the UE does not receive the random access response message correctly, and does not obtain the time adjustment indication information in the message, it cannot send the received downlink data to the eNB. Sending HARQ feedback, eNB fails to receive the ACK sent by UE, it will continue to retransmit downlink data until the maximum number of retransmissions is reached, eNB discards the data, reducing the number of data transmission messages, resulting in waste of system resources.

具体实施方式Detailed ways

为使本发明实施例的目的、技术方案、及优点更加清楚明白，以下参照附图并举实施例，对本发明实施例进一步详细说明。In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

本发明实施例提供的消息处理方法包括：eNB根据现有方法确定UE需要采用非竞争模式的随机接入时，设定QoS门限，该QoS门限根据具体的需求设定，如设定时延门限或丢包率，并根据下行数据的QoS要求，选择使用相应的数据确认方法，发送随机接入响应消息；UE根据接收到的随机接入响应消息包含的内容发送反馈消息。下面以实施例的方式分别介绍具体的消息处理方法，本发明实施例中以下行数据的时延要求为例进行说明。The message processing method provided by the embodiment of the present invention includes: when the eNB determines that the UE needs to use non-contention mode random access according to the existing method, set the QoS threshold, the QoS threshold is set according to specific requirements, such as setting the delay threshold or packet loss rate, and according to the QoS requirements of the downlink data, choose to use the corresponding data confirmation method, and send a random access response message; UE sends a feedback message according to the content contained in the received random access response message. The specific message processing methods are respectively introduced in the form of embodiments below, and the delay requirement of downlink data is taken as an example in the embodiments of the present invention.

如图2所示，为本发明实施例提供的一种消息处理方法的流程示意图，该流程包括：As shown in FIG. 2, it is a schematic flowchart of a message processing method provided by an embodiment of the present invention. The process includes:

S201、eNB接收下行数据，确定下行数据的业务时延要求小于等于时延门限，即下行数据的QoS要求高于QoS门限，采用显式方法确定UE是否正确接收到随机接入响应消息。S201. The eNB receives downlink data, determines that the service delay requirement of the downlink data is less than or equal to the delay threshold, that is, the QoS requirement of the downlink data is higher than the QoS threshold, and uses an explicit method to determine whether the UE correctly receives the random access response message.

S202-S203同现有技术的步骤S100-S101。S202-S203 are the same as steps S100-S101 in the prior art.

S204、eNB发送随机接入响应消息，该随机接入响应消息包含的ULGRANT指示后续某个TTI(Transmission Time Interval，传输时间间隔)内的上行传输资源。S204. The eNB sends a random access response message, and the ULGRANT contained in the random access response message indicates the uplink transmission resources in a subsequent TTI (Transmission Time Interval, transmission time interval).

S205、UE接收到随机接入响应消息后，发现UL GRANT指示后续某个TTI内的上行传输资源，则在这个上行传输资源上发送反馈消息，该消息可以携带但不限于：媒体控制信元(MAC Control Element，MCE)或者无线资源控制(Radio Resource Control，RRC)信令。S205. After receiving the random access response message, the UE finds that the UL GRANT indicates an uplink transmission resource in a subsequent TTI, and then sends a feedback message on the uplink transmission resource. The message may carry but is not limited to: media control information element ( MAC Control Element, MCE) or Radio Resource Control (Radio Resource Control, RRC) signaling.

S206、eNB接收到UE在上述上行传输资源上发送的消息后，确定UE已经接收到随机接入响应消息，开始发送下行数据。S206. After receiving the message sent by the UE on the uplink transmission resource, the eNB determines that the UE has received the random access response message, and starts sending downlink data.

本发明实施例中，通过显式确认方法，eNB获知UE已经接收到随机接入响应消息后，再发送下行数据，避免UE没有接收到随机接入响应消息，无法对下行数据进行确认反馈的问题，提高了传输消息的效率，节省了系统资源。In the embodiment of the present invention, through the explicit confirmation method, the eNB sends the downlink data after knowing that the UE has received the random access response message, so as to avoid the problem that the UE cannot confirm and feed back the downlink data without receiving the random access response message , which improves the efficiency of message transmission and saves system resources.

如图3所示，为本发明实施例提供的一种消息处理方法的流程示意图，该流程包括：As shown in FIG. 3, it is a schematic flowchart of a message processing method provided by an embodiment of the present invention, and the process includes:

S301、eNB接收下行数据，确定下行数据的业务时延要求大于时延门限，即下行数据的QoS要求低于QoS门限，采用隐式方法确定UE是否正确接收到随机接入响应消息。S301. The eNB receives downlink data, determines that the service delay requirement of the downlink data is greater than the delay threshold, that is, the QoS requirement of the downlink data is lower than the QoS threshold, and uses an implicit method to determine whether the UE correctly receives the random access response message.

S302-S303同现有技术的步骤S100-S101。S302-S303 are the same as steps S100-S101 in the prior art.

S304、eNB发送随机接入响应消息，该随机接入响应消息的UL GRANT中各比特都置为某个预定数值。S304. The eNB sends a random access response message, and each bit in the UL GRANT of the random access response message is set to a predetermined value.

本步骤中，eNB可以在RA-window内多次发送随机接入响应消息，增大UE成功接收该消息的概率。如果空口传输质量满足预定质量要求时，可以在发送预置次数的随机接入响应消息后，开始发送下行数据，其中，预定质量要求和发送随机接入响应消息的预置次数可以根据系统具体情况设定，以保证在发送预置次数的随机接入响应消息后，UE可以接收到随机接入响应消息。上述预置次数的随机接入响应消息包含的内容可以相同，也可以不同。如果eNB在同一时频资源上接收到多个UE发送的随机接入前导消息，则eNB可以将针对这些UE的随机接入响应信息放在同一个随机接入响应消息中，同时发送给多个UE，不同的UE根据RAPID(RandomAccess Preamble Identifier，随机接入前导码标识)区分自己的信息。为节省空口资源，优选地，eNB在发送的第二次及后续的随机接入响应消息中只包含有下行数据到达的UE的随机接入响应信息。In this step, the eNB may send the random access response message multiple times within the RA-window to increase the probability that the UE successfully receives the message. If the air interface transmission quality meets the predetermined quality requirements, the downlink data can be sent after sending a preset number of random access response messages. It is set to ensure that the UE can receive the random access response message after sending the random access response message for a preset number of times. The content included in the random access response messages for the preset number of times may be the same or different. If the eNB receives random access preamble messages sent by multiple UEs on the same time-frequency resource, the eNB can put the random access response information for these UEs in the same random access response message and send it to multiple UEs at the same time. UE, different UEs distinguish their own information according to RAPID (Random Access Preamble Identifier, Random Access Preamble Identifier). In order to save air interface resources, preferably, the second and subsequent random access response messages sent by the eNB only include the random access response information of the UE whose downlink data arrives.

S305、UE接收到随机接入响应消息后，发现UL GRANT的值相等，且是某个事先预定的值，则不发送反馈消息。S305. After receiving the random access response message, the UE finds that the values of UL GRANT are equal and are a predetermined value, and then do not send a feedback message.

S306、在eNB端，当RA-window超时后，再经过预置等待时间，都没有接收到UE发送的随机接入前导消息，则确认UE已经正确接收到随机接入响应消息，开始发送下行数据包。如果在预置等待时间内接收到UE发送的随机接入前导消息，则确认UE没有正确接收到随机接入响应消息，则不发送下行数据包，而是重新发送随机接入响应消息。S306. On the eNB side, when the RA-window times out, and after the preset waiting time, the random access preamble message sent by the UE is not received, confirm that the UE has correctly received the random access response message, and start sending downlink data Bag. If the random access preamble message sent by the UE is received within the preset waiting time, it is confirmed that the UE has not correctly received the random access response message, and the downlink data packet is not sent, but the random access response message is resent.

本步骤中，预置等待时间由系统根据实际情况设置，以达到数据发送效率最高。In this step, the preset waiting time is set by the system according to the actual situation, so as to achieve the highest data sending efficiency.

本步骤中，eNB根据随机接入前导消息中的Preamble，判断随机接入前导消息是不是同一个UE发送的，如果第二次收到的Preamble与第一次收到的Preamble相同，而且该Preamble尚未失效，则确认两次随机接入前导消息是同一个UE发送的。In this step, the eNB judges whether the random access preamble is sent by the same UE according to the Preamble in the random access preamble. If the Preamble received for the second time is the same as the Preamble received for the first time, and the Preamble If it has not expired, it is confirmed that the two random access preamble messages are sent by the same UE.

本发明实施例中，通过隐式确认方法，eNB获知UE已经接收到随机接入响应消息后，再发送下行数据，避免UE没有接收到随机接入响应消息，无法对下行数据进行确认反馈的问题，提高了消息发送的效率，节省了系统资源。In the embodiment of the present invention, through the implicit confirmation method, the eNB sends the downlink data after knowing that the UE has received the random access response message, so as to avoid the problem that the UE cannot confirm and feed back the downlink data without receiving the random access response message , which improves the efficiency of message sending and saves system resources.

具体地，当下行数据的QoS要求高于QoS门限时，发送单元402，用于向UE发送随机接入响应消息，该随机接入响应消息中包含的UL GRANT指示后续某个TTI内的上行传输资源，此时，接收单元401，还用于接收UE在该上行传输资源上发送的消息，该消息可以包含但不限于MCE或者RRC控制信令。Specifically, when the QoS requirement of the downlink data is higher than the QoS threshold, the sending unit 402 is configured to send a random access response message to the UE, and the UL GRANT included in the random access response message indicates the subsequent uplink transmission within a certain TTI Resource, at this time, the receiving unit 401 is also configured to receive a message sent by the UE on the uplink transmission resource, and the message may include but not limited to MCE or RRC control signaling.

当下行数据的QoS要求低于QoS门限时，发送单元402，还用于向UE发送随机接入响应消息，该随机接入响应消息的UL GRANT中各比特位置为某个预设的数值，此时，发送单元402，还用于在RA-window内发送多个随机接入响应消息；或者，该基站还包括定时单元403，用于在RA-window超时后，设定预置等待时间，如果在预置等待时间内，没有接收到UE发送的随机接入前导消息，通知发送单元402发送下行数据，如果在预置等待时间内，接收到UE发送的随机接入前导消息，通知发送单元402发送随机接入响应消息，此时，发送单元402，还用于根据定时单元403的通知消息发送随机接入响应消息或下行数据。When the QoS requirement of the downlink data is lower than the QoS threshold, the sending unit 402 is also configured to send a random access response message to the UE, where each bit position in the UL GRANT of the random access response message is a preset value, and here , the sending unit 402 is also used to send multiple random access response messages within the RA-window; or, the base station also includes a timing unit 403, used to set a preset waiting time after the RA-window times out, if Within the preset waiting time, if the random access preamble message sent by the UE is not received, notify the sending unit 402 to send downlink data, if within the preset waiting time, receive the random access preamble message sent by the UE, notify the sending unit 402 Sending a random access response message, at this time, the sending unit 402 is also configured to send a random access response message or downlink data according to a notification message from the timing unit 403 .

本发明实施例提供的基站，根据下行数据的QoS要求与QoS门限的关系发送随机接入响应消息，获知UE是否接收到随机接入响应消息后，再发送下行数据，避免UE没有接收到随机接入响应消息，无法对下行数据进行确认反馈的问题，提高了传输消息的效率，节省了系统资源。The base station provided by the embodiment of the present invention sends a random access response message according to the relationship between the QoS requirement of the downlink data and the QoS threshold, and sends the downlink data after knowing whether the UE has received the random access response message, so as to prevent the UE from not receiving the random access response message. The downlink data cannot be confirmed and fed back because of the response message input, which improves the efficiency of message transmission and saves system resources.
