数据传输方法、装置、网络侧设备及终端Data transmission method, device, network side equipment and terminal

技术领域technical field

本发明涉及通信领域，尤其涉及一种数据传输方法、装置、网络侧设备及终端。The present invention relates to the communication field, in particular to a data transmission method, device, network side equipment and terminal.

背景技术Background technique

物联网旨在实现人、设备与系统间的智能互连。目的是把所有物品通过信息传感设备与互联网连接起来，实现智能化识别和管理。物品的信息传感设备与互联网相结合，可以实现所有物品的远程感知和控制，由此生成一个更加智能的生产生活体系。所述物联网广泛用于智能电网、智能交通、环境保护、政府工作、公共安全、智能家居、智能消防、工业监测、老人护理、个人健康等多个领域。另外，在无线通信领域，用户终端如手机等也被普遍应用。本申请中，将物联网中物品的信息传感设备以及无线通信领域中的用户终端统称为终端。The Internet of Things aims to realize the intelligent interconnection of people, devices and systems. The purpose is to connect all items with the Internet through information sensing equipment to realize intelligent identification and management. Combining the information sensing equipment of items with the Internet can realize remote perception and control of all items, thus creating a more intelligent production and living system. The Internet of Things is widely used in many fields such as smart grid, smart transportation, environmental protection, government work, public safety, smart home, smart fire protection, industrial monitoring, elderly care, and personal health. In addition, in the wireless communication field, user terminals such as mobile phones are also widely used. In this application, information sensing devices of items in the Internet of Things and user terminals in the wireless communication field are collectively referred to as terminals.

当前，所述终端如用户设备（User Equipment，UE）均存在与网络侧设备如基站（eNB）之间进行小数据量数据传输的情况，而在进行所述小数据量数据传输时，每次都需要进行很多信令交互，尤其是无线承载（Radio Bearers，RB）配置与释放流程，占用了较多系统资源，效率低下。Currently, the terminal such as user equipment (User Equipment, UE) may perform data transmission with a small amount of data with a network side device such as a base station (eNB), and when performing the data transmission with a small amount of data, each Both require a lot of signaling interaction, especially the Radio Bearers (RB) configuration and release process, which takes up a lot of system resources and is inefficient.

一种解决上述问题的方法是保证终端处于失步态的永久在线。在该方法下，终端转入失步状态时，不释放小区无线网络临时标识（Cell-Radio Network TemporaryIdentifier，C-RNTI），网络侧设备为终端分配的C-RNTI一直被终端占用。所述C-RNTI是RNTI的一个子集，一般的，网络侧设备从RNTI中为终端分配一个RNTI作为所述C-RNTI。A method to solve the above problem is to ensure that the terminal is permanently online in an out-of-gait state. Under this method, when the terminal enters the out-of-synchronization state, the Cell-Radio Network Temporary Identifier (C-RNTI) is not released, and the C-RNTI allocated by the network side device for the terminal is always occupied by the terminal. The C-RNTI is a subset of the RNTI. Generally, the network side device allocates an RNTI from the RNTIs to the terminal as the C-RNTI.

由于当前无线网络临时标识（Radio Network Temporary Identifier，RNTI）的长度为两个字节，最多支持6万多个终端，如果大量终端保持永久在线，每个终端都一直占用一个C-RNTI，会导致RNTI资源紧张，限制保持永久在线的终端的数量。Since the length of the current Radio Network Temporary Identifier (RNTI) is two bytes, it supports up to more than 60,000 terminals. If a large number of terminals remain permanently online, each terminal will always occupy a C-RNTI, which will cause RNTI resources are tight, limiting the number of terminals that remain permanently online.

参见图1，为本发明上行数据传输方法第一实施例示意图，该方法包括：Referring to Fig. 1, it is a schematic diagram of the first embodiment of the uplink data transmission method of the present invention, the method includes:

步骤101：网络侧设备为终端分配第一标识，将所述第一标识发送给所述终端；所述第一标识唯一标识所述终端；Step 101: The network side device assigns a first identifier to the terminal, and sends the first identifier to the terminal; the first identifier uniquely identifies the terminal;

步骤102：所述网络侧设备接收所述终端发送的第一控制消息，所述第一控制消息在所述终端有上行数据需要传输时发送，且所述终端处于失步状态并已释放所述终端的C-RNTI；Step 102: The network side device receives a first control message sent by the terminal, the first control message is sent when the terminal has uplink data to transmit, and the terminal is in an out-of-sync state and has released the C-RNTI of the terminal;

步骤103：所述网络侧设备确定所述第一控制消息中是否携带所述终端的第一标识；若所述第一控制消息携带所述终端的第一标识，则所述网络侧设备将接收到的所述第一控制消息发送给所述终端，以便终端确定接收到的所述网络侧设备发送的消息与终端自身发送的第一控制消息相同时，进行上行数据的传输。Step 103: The network-side device determines whether the first control message carries the first identifier of the terminal; if the first control message carries the first identifier of the terminal, the network-side device will receive The received first control message is sent to the terminal, so that the terminal performs uplink data transmission when it determines that the received message sent by the network side device is the same as the first control message sent by the terminal itself.

本实施例中，网络侧设备为终端分配第一标识，并且，在终端处于失步状态并已释放终端的C-RNTI的情况下，如果终端有上行数据需要传输，则接收终端发送的第一控制消息，为将接收到的所述第一控制消息发送给终端，以便终端确定接收到的所述网络侧设备发送的消息与终端自身发送的第一控制消息相同时，进行上行数据的传输，从而保证了终端上行数据传输的实现；而且，由于终端在处于失步状态下已经释放了C-RNTI，从而终端并未一直占用RNTI，缓解了RNTI资源紧张的问题。In this embodiment, the network side device assigns a first identifier to the terminal, and when the terminal is in an out-of-sync state and has released the C-RNTI of the terminal, if the terminal has uplink data to transmit, the first identifier sent by the terminal is received. The control message is to send the received first control message to the terminal, so that the terminal performs uplink data transmission when it determines that the received message sent by the network side device is the same as the first control message sent by the terminal itself, In this way, the realization of the uplink data transmission of the terminal is guaranteed; moreover, since the terminal has released the C-RNTI in the out-of-synchronization state, the terminal does not occupy the RNTI all the time, which alleviates the problem of RNTI resource shortage.

参见图2，为本发明上行数据传输方法第二实施例示意图，该方法包括：Referring to FIG. 2, it is a schematic diagram of the second embodiment of the uplink data transmission method of the present invention, the method includes:

步骤201：终端接收网络侧设备发送的第一标识，所述第一标识由所述网络侧设备为所述终端分配，所述第一标识唯一标识所述终端；Step 201: The terminal receives a first identifier sent by a network-side device, the first identifier is assigned to the terminal by the network-side device, and the first identifier uniquely identifies the terminal;

步骤202：所述终端确定有上行数据需要传输时，且所述终端为处于失步状态并已释放所述终端的小区无线网络临时标识C-RNTI后，向所述网络侧设备发送第一控制消息，所述第一控制消息中包括所述终端的第一标识；Step 202: When the terminal determines that there is uplink data to be transmitted, and the terminal is in an out-of-sync state and has released the cell radio network temporary identifier C-RNTI of the terminal, send a first control to the network side device message, where the first control message includes the first identifier of the terminal;

步骤204：所述终端确认接收到的第一控制消息与所述终端自身发送的第一控制消息相同，则所述终端进行上行数据的传输。Step 204: The terminal confirms that the received first control message is the same as the first control message sent by the terminal itself, and then the terminal performs uplink data transmission.

本实施例中，网络侧设备为终端分配第一标识，当终端有上行数据需要传输时，通过第一标识接入网络侧设备，解决接入竞争，从而保证了上行数据的传输；并且，终端在转入失步状态时，释放C-RNTI，从而在失步状态下不再占用C-RNTI，从而缓解了RNTI资源紧张的问题。In this embodiment, the network-side device assigns a first identifier to the terminal, and when the terminal has uplink data to transmit, it accesses the network-side device through the first identifier to resolve access competition, thereby ensuring the transmission of uplink data; and, the terminal When entering the out-of-synchronization state, the C-RNTI is released, so that the C-RNTI is no longer occupied in the out-of-synchronization state, thereby alleviating the problem of RNTI resource shortage.

参见图3，为本发明上行数据传输方法第三实施例示意图，在该方法中，以终端为UE，网络侧设备为eNB为例，且该方法应用于UE发送上行数据的场景下。参见图3，该方法包括：Referring to FIG. 3 , it is a schematic diagram of the third embodiment of the uplink data transmission method of the present invention. In this method, the terminal is UE and the network side device is eNB as an example, and this method is applied to the scenario where UE sends uplink data. Referring to Figure 3, the method includes:

步骤301：无线资源控制（RRC，Radio Resource Control）连接建立时，UE向eNB发送UE的类型信息。Step 301: When a radio resource control (RRC, Radio Resource Control) connection is established, the UE sends UE type information to the eNB.

在一种可能的实现方式中，UE可以通过RRC连接建立过程中的RRC连接建立结束（RRC Connection Setup Complete）消息来携带所述UE的类型信息。In a possible implementation manner, the UE may carry the type information of the UE through an RRC Connection Setup Complete (RRC Connection Setup Complete) message during the RRC connection establishment process.

步骤302：eNB接收UE的类型信息，根据UE的类型为UE分配第一标识，并将为UE分配的第一标识发送至UE。Step 302: The eNB receives the type information of the UE, allocates a first identity to the UE according to the type of the UE, and sends the first identity allocated to the UE to the UE.

在一种可能的实现方式中，eNB可以通过RRC连接重配置（RRC ConnectionReconfiguration）消息来携带所述第一标识。In a possible implementation manner, the eNB may use an RRC Connection Reconfiguration (RRC ConnectionReconfiguration) message to carry the first identifier.

其中，所述第一标识可以通过以下方式实现：Wherein, the first identification can be realized in the following ways:

在第一种可能的实现方式中，所述第一标识可以为：组RNTI以及组内序号；In a first possible implementation manner, the first identifier may be: a group RNTI and a sequence number within the group;

例如，可以将部分RNTI预设为组RNTI，并且为每个组RNTI预设至少一个组内序号；并且，根据UE的类型对组RNTI以及组RNTI的组内序号进行划分；For example, some RNTIs may be preset as group RNTIs, and at least one group RNTI is preset for each group RNTI; and, the group RNTI and the group RNTI group number are divided according to the type of UE;

例如，将RNTI中的a、b、c、d共4个RNTI预设为组RNTI，并且为每一个组RNTI预设5个组内序号，分别为1、2、3、4、5；并且，根据UE的类型A、B将所述组RNTI以及组内序号划分如下：组RNTI中的a、b两个组RNTI及其组内序号划分给UE类型A，组RNTI中的c、d两个组RNTI及其组内序号划分给UE类型B。For example, preset 4 RNTIs of a, b, c, and d in the RNTI as a group RNTI, and preset 5 internal serial numbers for each group RNTI, which are 1, 2, 3, 4, and 5 respectively; and According to the types A and B of the UE, the group RNTI and the serial number in the group are divided as follows: the two group RNTIs a and b in the group RNTI and their internal serial numbers are assigned to the UE type A, and the two group RNTIs in the group RNTI Group RNTIs and their sequence numbers are assigned to UE type B.

此时，如果本步骤中UE类型信息为A，则eNB可以从a、b及其组内序号中为UE分配组RNTI以及组内序号，例如，为UE分配组RNTI为a，组内序号为1。At this time, if the UE type information in this step is A, the eNB can assign the group RNTI and the group sequence number to the UE from a, b and their group sequence numbers. For example, assign the group RNTI to the UE as a, and the group sequence number is 1.

在第二种可能的实现方式中，所述第一标识可以为短格式临时移动用户标识（S-TMSI）；此时，由于S-TMSI本来就是分配给UE的一种临时标识，eNB无需重新为UE分配该S-TMSI，因此，步骤301可以省略。In the second possible implementation, the first identity may be a Short Temporary Mobile Subscriber Identity (S-TMSI); at this time, since the S-TMSI is originally a temporary identity allocated to the UE, the eNB does not need to The S-TMSI is allocated to the UE, therefore, step 301 can be omitted.

在第三种可能的实现方式中，所述第一标识可以为：在现有RNTI的两个字节的基础上增加至少1个字节，从而得到新标识作为第一标识。In a third possible implementation manner, the first identifier may be: adding at least one byte to the two bytes of the existing RNTI, so as to obtain a new identifier as the first identifier.

在第四种可能的实现方式中，所述第一标识可以为其他与RNTI不同的新标识，为了保证新标识的数量，可以将新标识设置为至少两个字节，具体新标识如何实现，这里并不限制。例如，可以预先设置一套与RNTI完全无关的新标识，并且，根据UE的类型信息对该套新标识进行划分，从而本步骤中也可以根据UE的类型信息为UE分配所述新标识。In a fourth possible implementation, the first identifier can be other new identifiers different from RNTI. In order to ensure the number of new identifiers, the new identifier can be set to at least two bytes. Specifically, how to implement the new identifier, There is no limit here. For example, a set of new identities completely unrelated to RNTI may be set in advance, and the set of new identities may be divided according to UE type information, so that in this step, the UE may also be assigned the new identities according to UE type information.

需要说明的是，第一标识通过第二～四种实现方式实现时，如果第一标识的传输参考现有技术中C-RNTI的传输，需要对现有技术中C-RNTI的传输方式进行适应性的改变，例如，第一标识是在现有RNTI的基础上增加至少1个字节时，如果使用现有RNTI的相关传输方式实现第一标识的传输，一般需要物理下行控制信道（PDCCH）的循环冗余校验码（CRC）同样加长一个字节，所有涉及RNTI分配及指示的消息或MAC层的均需增加一个字节的补充，即：现有技术中用于传输C-RNTI的MAC层控制消息为2个字节，在传输第一标识时，需要扩展一个字节，变为3个字节；现有技术中传输C-RNTI的RRC连接重配置请求以及TC-RNTI均需要扩展1个字节，变为3个字节；RRC消息中涉及指示及分配各种RNTI的IE均需要扩展为3个字节。以上仅为本发明实施例提供的一种实现方式，但并不用于进行C-RNTI的传输方式的限定，在实际应用中，还可以通过其他方式实现所述C-RNTI的传输，本发明并不限制。It should be noted that when the first identification is realized through the second to fourth implementation methods, if the transmission of the first identification refers to the transmission of the C-RNTI in the prior art, it is necessary to adapt the transmission mode of the C-RNTI in the prior art For example, when the first identifier is to add at least 1 byte to the existing RNTI, if the transmission of the first identifier is realized by using the relevant transmission method of the existing RNTI, the physical downlink control channel (PDCCH) is generally required The cyclic redundancy check code (CRC) of the RNTI is also lengthened by one byte, and all messages related to RNTI allocation and indication or the MAC layer need to be supplemented by one byte, that is, the C-RNTI used to transmit C-RNTI in the prior art The MAC layer control message is 2 bytes. When transmitting the first identifier, it needs to be extended by one byte to become 3 bytes; in the prior art, both the RRC connection reconfiguration request and the TC-RNTI of C-RNTI need to be transmitted. Extend 1 byte to 3 bytes; IEs involved in indicating and allocating various RNTIs in the RRC message need to be extended to 3 bytes. The above is only an implementation mode provided by the embodiment of the present invention, but it is not used to limit the transmission mode of the C-RNTI. In practical applications, the transmission of the C-RNTI can also be realized in other ways. The present invention does not not limited.

步骤303：UE中的时间调整定时器（TAT）超时时，UE转入失步状态，释放C-RNTI。Step 303: When the Time Adjustment Timer (TAT) in the UE expires, the UE enters an out-of-sync state and releases the C-RNTI.

一般的，本实施例中UE转入失步状态可以参考现有技术中UE转入失步状态的处理，区别仅在于：本发明实施例中UE释放C-RNTI，而现有技术中UE未释放C-RNTI。当然，在实际应用中，除了UE释放C-RNTI外，UE转入失步状态的其他处理也可以与现有技术中UE转入失步状态的处理不相同，这里并不限定。Generally, in this embodiment, when the UE enters the out-of-synchronization state, you can refer to the processing of the UE entering the out-of-synchronization state in the prior art. Release C-RNTI. Of course, in practical applications, except that the UE releases the C-RNTI, other processes for the UE to enter the out-of-synchronization state may also be different from those in the prior art, which are not limited here.

步骤304：UE需要传输上行数据时，执行随机接入过程，向eNB发送前导码（preamble）。Step 304: When the UE needs to transmit uplink data, it performs a random access procedure and sends a preamble (preamble) to the eNB.

步骤305：eNB接收所述前导码，向UE发送随机接入响应（Random AccessResponse）消息，所述随机接入响应消息中包括eNB为UE分配的临时小区无线网络临时标识（Temporary Cell-Radio Network Temporary Identifier，TC-RNTI）。Step 305: The eNB receives the preamble and sends a Random Access Response (Random Access Response) message to the UE. The Random Access Response message includes the Temporary Cell-Radio Network Temporary Identity (Temporary Cell-Radio Network Temporary) allocated by the eNB for the UE. Identifier, TC-RNTI).

步骤306：UE接收所述随机接入响应消息，向eNB发送第一控制消息，第一控制消息中携带所述第一标识。Step 306: The UE receives the random access response message, and sends a first control message to the eNB, where the first control message carries the first identifier.

在一种可能的实现方式中，所述第一控制消息可以通过介质访问控制（MAC，MediaAccess Control）层的控制消息实现。In a possible implementation manner, the first control message may be implemented through a control message of a Media Access Control (MAC, MediaAccess Control) layer.

在一种可能的实现方式中，当步骤301中所述第一标识包括组RNTI和组内序号时，本步骤中所述UE向eNB发送第一控制消息可以包括：In a possible implementation manner, when the first identifier in step 301 includes a group RNTI and an intra-group sequence number, sending the first control message from the UE to the eNB in this step may include:

UE根据所述组内序号计算最近可以使用组RNTI的时刻，在计算得到的时刻发送所述第一控制消息。此时，所述第一控制消息可以通过现有技术中UE向eNB发送的携带C-RNTI的MAC层控制消息实现，区别在于第一控制消息中携带的不是C-RNTI，而是组RNTI和组内序号，另外，此时组内序号可以省略。The UE calculates the latest time when the group RNTI can be used according to the sequence number in the group, and sends the first control message at the calculated time. At this time, the first control message can be implemented by the MAC layer control message carrying the C-RNTI sent by the UE to the eNB in the prior art, the difference is that the first control message does not carry the C-RNTI, but the group RNTI and The serial number in the group, in addition, the serial number in the group can be omitted at this time.

具体的，可以按照组RNTI的组内序号将一个周期例如1s划分为组内序号个子时间段，每一组内序号对应一个子时间段，则可以按照UE对应的组内序号来确定最近一个周期中该组内序号对应的子时间段，该子时间段即为UE最近可以使用组RNTI的时刻。例如，假设组RNTI为a，包括的组内序号为1～5，则可以将1s划分为5个子时间段，组内序号1～5依次对应5个子时间段，那么，如果UE的组RNTI为a，组内序号为3，UE最近可以使用组RNTI的时刻为下1s的第3个子时间段。通过以上处理，可以使得组RNTI相同、组内序号不同的UE实现组RNTI时间上的复用。Specifically, a period such as 1 s can be divided into sub-time periods according to the intra-group serial number of the group RNTI, and each intra-group serial number corresponds to a sub-time period, and the latest period can be determined according to the intra-group serial number corresponding to the UE The sub-time period corresponding to the serial number in the group, the sub-time period is the moment when the UE can use the group RNTI most recently. For example, assuming that the group RNTI is a, and the sequence numbers included in the group are 1 to 5, then 1s can be divided into 5 sub-time periods, and the sequence numbers 1 to 5 in the group correspond to the 5 sub-time periods in turn. Then, if the group RNTI of the UE is a, the serial number in the group is 3, and the latest time when the UE can use the group RNTI is the third sub-time period of the next 1s. Through the above processing, UEs with the same group RNTI and different sequence numbers in the group can be multiplexed in terms of group RNTI time.

步骤307：eNB接收所述第一控制消息，判断所述第一控制消息中携带所述第一标识时，将接收到的所述第一控制消息发送给UE。Step 307: The eNB receives the first control message, and when determining that the first control message carries the first identifier, sends the received first control message to the UE.

eNB判断所述第一控制消息中不携带所述第一标识时，eNB如何处理这里不限定。When the eNB determines that the first control message does not carry the first identifier, how the eNB handles it is not limited here.

步骤308：UE接收eNB发送的消息，确认接收到的消息与UE自身发送的第一控制消息相同时，进行上行数据的发送。Step 308: The UE receives the message sent by the eNB, and when confirming that the received message is the same as the first control message sent by the UE itself, sends uplink data.

在实际应用中，UE发送第一控制消息，其他一个或多个UE可能同时发送控制消息，例如类似于第一控制消息的消息，或者现有技术中的控制消息，由于每个UE发送的控制消息不同，所以，UE接收到eNB反馈的控制消息，将该控制消息与自身发送的控制消息对比，如果相同，则认为eNB识别出了该UE，解决了接入竞争。由于步骤307中eNB向UE发送的消息是第一控制消息，因此，本步骤中UE必然判断接收到的消息与UE自身发送的第一控制消息相同，确认已经解决接入竞争。之后，UE就可以向eNB发送上行数据。In practical applications, a UE sends a first control message, and one or more other UEs may send control messages at the same time, such as a message similar to the first control message, or a control message in the prior art, because the control message sent by each UE The messages are different. Therefore, the UE receives the control message fed back by the eNB and compares the control message with the control message sent by itself. If they are the same, it is considered that the eNB has recognized the UE and the access contention has been resolved. Since the message sent by the eNB to the UE in step 307 is the first control message, in this step, the UE must judge that the received message is the same as the first control message sent by the UE itself, and confirm that the access contention has been resolved. Afterwards, the UE can send uplink data to the eNB.

本实施例中，eNB为UE分配第一标识；当UE有上行数据需要传输时，UE通过第一标识接入eNB，从而保证UE能够正常传输上行数据；而且，UE中的TAT超时时，UE转入失步状态，释放C-RNTI，从而UE在失步状态下不再一直占用RNTI，从而缓解了RNTI资源紧张的问题。In this embodiment, the eNB assigns the first identifier to the UE; when the UE has uplink data to transmit, the UE accesses the eNB through the first identifier, thereby ensuring that the UE can transmit uplink data normally; and, when the TAT in the UE expires, the UE The UE enters the out-of-synchronization state and releases the C-RNTI, so that the UE does not occupy the RNTI all the time in the out-of-synchronization state, thereby alleviating the problem of RNTI resource shortage.

In this method, the terminal is UE and the network side device is eNB as an example, and this method is applied to the scenario where UE sends uplink data. Referring to Figure 3, the method includes:

步骤402：eNB接收UE的类型信息，按照UE的类型为UE分配第一标识。Step 402: The eNB receives the type information of the UE, and allocates a first identifier to the UE according to the type of the UE.

其中，本步骤401～步骤402的实现请参考步骤301～步骤302中的描述，这里不赘述。Wherein, for the implementation of steps 401 to 402, please refer to the descriptions in steps 301 to 302, which will not be repeated here.

步骤403：eNB确定UE对应的失步计时器超时时，向UE发送失步指示信令，所述失步指示信令中携带所述第一标识。Step 403: When the eNB determines that the out-of-synchronization timer corresponding to the UE expires, it sends an out-of-synchronization indication signaling to the UE, and the out-of-synchronization indication signaling carries the first identifier.

所述失步指示信令可以通过扩展的RRC消息实现。The out-of-synchronization indication signaling may be implemented through an extended RRC message.

步骤404：UE接收所述失步指示信令，转入失步状态，释放C-RNTI。Step 404: The UE receives the out-of-synchronization indication signaling, turns into an out-of-synchronization state, and releases the C-RNTI.

步骤405～步骤409与步骤304～步骤308相似，这里不赘述。Steps 405 to 409 are similar to steps 304 to 308 and will not be repeated here.

本实施例中，eNB为UE分配第一标识；当UE有上行数据需要传输时，UE通过第一标识接入eNB，从而保证UE能够正常传输上行数据；而且，eNB向UE发送失步指示信令后，UE转入失步状态，释放C-RNTI，从而UE在失步状态下不再一直占用RNTI，从而缓解了RNTI资源紧张的问题。In this embodiment, the eNB assigns the first identifier to the UE; when the UE has uplink data to transmit, the UE accesses the eNB through the first identifier, thereby ensuring that the UE can transmit uplink data normally; moreover, the eNB sends an out-of-synchronization indication message to the UE After the command, the UE enters the out-of-synchronization state and releases the C-RNTI, so that the UE does not occupy the RNTI all the time in the out-of-synchronization state, thereby alleviating the problem of RNTI resource shortage.
