- the MTC device In many application scenarios of MTC, the MTC device only sends small data volume data to the network side. If the traditional data transmission method is used, a large signaling overhead will be generated, resulting in low system efficiency. If the control data is transmitted by transmitting the user data, the small data volume can be transmitted, although the signaling can be reduced. Overhead, improve system efficiency, but when the system is heavily loaded, it may cause or aggravate the transmission of signaling and processing congestion. The following is an analysis of the occurrence of this phenomenon.
- FIG. 1 is a schematic diagram of the network architecture of the LTE (Long Term Evolution) system.
- LTE Long Term Evolution
- the surface carriers are respectively responsible for the independent network element MME (Mobile Management Entity) and the S-GW (Serving Gateway).
- MME Mobile Management Entity
- S-GW Serving Gateway
- the main functions of the MME are NAS (Non-Access Stratum) signaling establishment, NAS signaling security, signaling establishment across core networks, and tracking when UE (User Equipment) is in IDLE mode. Services, roaming services, authorization and bearer management, etc.
- the S-GW is a gateway point for eNB (Evolved Base Station) handover, forwarding 2G / 3G and other system service gateway points, completing buffering of downlink packets, some initialization work, prescribed interception interception, packet routing, and forwarding.
- P-GW PDN Gateway, PDN Gateway; PDN: Packet Data Network, Packet Data Network) for policy enforcement, packet filtering, specified interception, IP (Internet Protocol) address allocation, and charging function of the UE , package reproduction, etc.
- the control signaling between the UE, the eNB and the core network is processed by the MME; the user data is transmitted to the P-GW through the S-GW, and then transmitted to the external APN (Access Point Name, access point name) by the P-GW. )node. Since the coupling of control signaling and user data is reduced, when a new service occurs, only the network element responsible for the user plane is upgraded, and the control information transmission is not affected, thereby greatly reducing the complexity of network maintenance and Equipment upgrade costs.
- the signaling flow of the control plane is analyzed below.
- Figure 2 is a schematic diagram of the signaling process in the connection establishment process. As shown in the figure, in the idle state of the UE in the LTE system, if data is sent to the network side, the signaling process in the connection establishment process is as follows:
- Step 201 When the UE has data to be sent, first, according to the random access resource information configured by the system, wait for a RACH (Random Access Channel) scheduling period, select a preamble, and send Msgl to the eNB. Message 1).
- RACH Random Access Channel
- Step 202-Step 204 After receiving the preamble (ie, Msgl) sent by the UE, the eNB A random access response message (Msg2, message 2) is sent to the UE in the random access response window. A random access response message (Msg2) can respond to a random access request (preamble) of multiple UEs.
- Msg2 is scheduled by RA-RNTI (Random Access-RNTI; RA: Random Access, Random Access; RNTI: Radio Network Temporary Identity), DCI (Downlink Control Information), RA - RNTI is determined by the location of the time-frequency resource from which Msgl is sent.
- the contents of Msg2 include: backoff (return) parameter, preamble identifier corresponding to Msgl, uplink transmission TA (Tiing Alignment), uplink resource allocated by Msg3 (Msg3 scheduling information), temporary C-RNTI (cell- RNTI; C: Cell, cell).
- the backoff parameter is used to indicate the average delay of the next time the UE initiates random access if the random access fails.
- the UE determines the random access response sent to itself by using the preamble identifier in the RA-RNTI and the Msg2. If the preamble corresponding to the preamble identifier in the Msg2 includes the preamble when the random access is initiated by itself, the UE considers that it successfully receives the random access. In the response message, Msg3 will be sent to the network side. If the UE does not correctly receive the Msg2, the delay of the next random access is determined according to the delay limit of the backoff parameter, and the random access resource is selected to initiate the next random access. After the maximum number of random accesses is reached, the UE (Media Access Control) layer reports a random access problem to the RRC (Radio Resource Control) layer.
- RRC Radio Resource Control
- Step 205 After receiving the Msg2, the UE sends the Msg3 on the uplink resource allocated by the Msg2.
- Msg3 contains different content for different scenarios.
- the RRC connection setup request message generated by the RRC layer is carried in the Msg3.
- the eNB and the UE complete the final contention resolution through Msg4.
- the Msg4 content corresponds to the content of Msg3.
- the Msg4 carries the UE to resolve the Contention Resolution Identity (MAC CE), which includes the CCCH (Common Control Channel) SDU (Service Data) transmitted by the UE in Msg3. Unit, service data unit), after receiving the MAC CE, the UE compares with its own RRC layer information to complete the contention resolution.
- Msg4 can include RRC connection construction. The message is used to establish the SRB1 (Signaling Radio Bearer1) of the UE.
- Step 209 - Step 210 After completing the contention resolution, the UE establishes a signaling radio bearer 1 (SRB1) according to the information in the RRC connection setup message, and sends an RRC connection setup complete message to the network.
- SRB1 signaling radio bearer 1
- the NAS service request message may be carried and sent to the network side when the RRC connection setup complete message is sent.
- Step 211 - Step 215 After receiving the RRC connection setup complete message, the eNB sends the carried NAS service request message to the MME, and is used to request the MME to establish a related connection between the eNB corresponding to the UE and the core network element (with the MME)
- the control plane is connected and carried with the S1 interface of the S-GW).
- the MME notifies the eNB of the information of the UE corresponding connection.
- Step 216 - Step 217 The eNB sends an SMC (Security Mode Command) and an RRC Connection Reconfiguration message to the UE. It is used to activate the security of the UE and establish a DRB (Data Radio Bearer) and other signaling radio bearers (SBR2) for the UE.
- SMC Security Mode Command
- RRC Connection Reconfiguration message It is used to activate the security of the UE and establish a DRB (Data Radio Bearer) and other signaling radio bearers (SBR2) for the UE.
- DRB Data Radio Bearer
- SBR2 signaling radio bearers
- SMC Security Mode Command
- RRC Connection Reconfiguration can be sent in one RRC message or separately.
- Step 218 After the security activation and the DRB and SRB2 configurations are completed, the UE sends a security mode complete message and an RRC connection reconfiguration complete message to the network side.
- the user plane data of the UE is carried by the DRB and the SI, and is sent to the core network through the eNB and the S-GW.
- the control signaling of the UE and the core network is sent to the MME through the SRB and the control plane connection between the eNB and the MME.
- the UE For the UE in the detach state, when the UE needs to send data to the network side, the UE needs to initiate an attach process and attach to the network. In addition, in order to determine the legitimacy of the user, the process needs to be performed through the authentication process. confirm.
- the signaling process will be more complicated than the process shown in Figure 2. It will not be described in detail here. See the description in the related protocol.
- the MTC terminal Although in MTC, the number of MTC terminals will greatly exceed the number of traditional communication terminals, in many MTC application scenarios, the amount of data reported each time is not very large (usually tens to hundreds of bytes). One or several sub-frames can be transferred. However, in order to transmit the data, the MTC terminal needs to establish the DRB through the above signaling process according to the current data transmission mode, and then the data can be sent to the network side through the DRB and the SI bearer. As can be seen from the above signaling process, The signaling overhead required to transmit small amounts of data will be relatively large, thereby severely degrading system efficiency.
- the small data volume user plane information transmission can be transmitted by means of establishing a DRB or SI bearer by means of a conventional method of transmitting DRB and SI bearers, for example, by transmitting a small amount of data information of the user, such as directly transmitting.
- the small data volume data is directly carried in the RRC signaling (such as a connection establishment request or an RRC connection setup complete message), and is sent to the eNB through the control plane connection, thereby reducing the number of signals required for transmitting the small data amount information. Consumption, and the use of air interface resources.
- control plane to transmit small data volumes to the user can increase system efficiency, but this approach also increases the load on the control plane.
- the way in which the control plane transmits the user small data volume data may cause or increase the congestion of the control plane transmission and/or processing, such as signaling processing congestion of the eNB, signaling of the eNB and the MME connection. Transmission congestion. Since one MME can connect multiple eNBs, the signaling processing congestion of the MME may also be caused when the control plane signaling of multiple eNBs is sent to the MME for processing.
- a data transmission mode scheme is proposed, where the network side sends relevant indication information for transmitting small data volume data by using a user control plane to indicate whether the MTC device can use the control.
- the method of transmitting user data transmits small data volume data, thereby improving the performance of the LTE system supporting machine type communication.

"一种机器类通信设备的数据传输处理方法及设备"的中国专利申请的优先权,其全部内容通过 引用结合在本申请中。 技术领域
本发明涉及移动通信领域, 特别涉及一种机器类通信设备的数据传输处 理方法及设备。 背景技术
MTC ( Machine Type Communications, 机器类通信)通信作为一种新型 的通信理念, 其目的是将多种不同类型的通信技术有机结合, 如: 机器对机 器通信、 机器控制通信、 人机交互通信、 移动互联通信, 从而推动社会生产 和生活方式的发展。预计未来人对人通信的业务可能仅占整个终端市场的 1 /3 , 而更大数量的通信是 MTC 通信业务。 有时, MTC 通信又称为 M2M ( Machine-to-machine, 机器间)通信或物联网。
当前的移动通信网络是针对人与人之间的通信设计的, 如: 网络容量的 确定等。 如果希望利用移动通信网络来支持 MTC通信, 就需要根据 MTC通 信的特点对移动通信系统的机制进行优化, 以便能够在对传统的人与人通信 不受或受较小影响的情况下, 更好地实现 MTC通信。
当前认识到的 MTC通信可能存在的一些特点有:
MTC终端具有低移动性;
MTC终端与网络侧进行数据传输的时间是可控的;
MTC网络与网络侧进行的数据传输对实时性要求不高, 即: 具有时间容 忍性;
MTC终端能量受限, 要求极低的功率消耗;
MTC终端和网络侧之间只进行小数据量的信息传输;
MTC终端可以以组为单位进行管理; 一个实际的 MTC终端可以具有上述的一个或多个特点。
在许多 MTC的应用场景中, MTC设备只向网络侧发送小数据量数据, 如果釆用传统的数据发送方式, 那么将会产生较大的信令开销, 导致系统效 率较低; 如果釆用控制面传输用户数据的方式传输小数据量数据, 虽然可以 降低信令开销, 提高系统效率, 但其不足在于:
当系统负荷较重时可能会引起或加重信令的传输和处理拥塞。 发明内容
本发明所解决的技术问题在于提供了一种机器类通信设备的数据传输处 理方法及设备,用以解决现有技术中 MTC在釆用控制面传输用户小数据量数 据时, 可能会弓 I起或加重信令的传输和处理拥塞的问题。
本发明实施例中提供了一种 MTC设备的数据传输处理方法, 包括如下步 骤:
网络侧确定 MTC设备釆用控制面传输用户小数据量数据的方式; 网络侧指示 MTC设备按确定的方式釆用控制面传输用户小数据量数据。 本发明实施例中提供了一种 MTC设备的数据传输处理方法, 包括如下步 骤:
MTC设备确定网络侧的指示, 所述指示用于指示 MTC设备釆用控制面 传输用户小数据量数据的方式;
MTC设备根据网络侧的指示来釆用控制面传输用户小数据量数据。
本发明实施例中提供了一种网络侧设备, 包括:
确定模块, 用于确定 MTC设备釆用控制面传输用户小数据量数据的方 式;
指示模块,用于指示 MTC设备按确定的方式釆用控制面传输用户小数据 量数据。
本发明实施例中提供了一种 MTC设备, 包括:
确定模块, 用于确定网络侧的指示, 所述指示用于指示 MTC设备釆用控 制面传输用户小数据量数据的方式;
传输模块, 用于根据网络侧的指示来釆用控制面传输用户 j、数据量数据。 本发明有益效果如下:
由于网络侧发送釆用控制面传输用户数据方式传输小数据量数据的相关 指示信息,使得 MTC设备能够根据网络发送的相关指示信息判断是否能够釆 用控制面传输用户数据方式发送数据, 从而一方面能够利用控制面传输用户 数据方式传输小数据量数据提高系统效率, 另一方面, 可以避免全部使用控 制面传输用户数据方式传输小数据量数据时可能造成或加重信令传输和 /或处 理拥塞, 提高了 LTE系统支持 MTC的性能。 附图说明

发明人在发明过程中注意到:
在许多 MTC的应用场景中, MTC设备只向网络侧发送小数据量数据。 如果釆用传统的数据发送方式将会产生较大的信令开销, 导致系统效率较低; 如果釆用控制面传输用户数据的方式传输小数据量数据, 虽然可以降低信令
开销, 提高系统效率, 但是当系统负荷较重时, 则有可能引起或加重信令的 传输和处理拥塞。 下面对这一现象的产生进行分析。
图 1为 LTE ( Long Term Evolution, 长期演进) 系统网络架构示意图, 如 图所示, 为了便于新业务的开展, LTE 系统釆用了用户面与控制面分离的设 计方式, 控制面信令与用户面 载分别由独立的网元 MME ( Mobile Management Entity, 移动管理实体)和 S-GW ( Serving Gateway, 服务网关) 来负责。 MME主要功能是 NAS ( Non Access Stratum, 非接入层 )信令建立、 NAS信令安全、 跨核心网的信令建立、 当 UE ( User Equipment , 用户设备 ) 在 IDLE (空闲)模式时的跟踪服务、 漫游服务、 授权和承载管理等。 S-GW 为 eNB (演进基站)切换时的关口点、 转发 2G / 3G以及其他系统业务的关 口点, 完成下行包的緩冲、 一些初始化工作、 规定的拦截侦听、 包路由和转 发等。 P-GW ( PDN Gateway, PDN网关; PDN: Packet Data Network, 分组 数据网络)用于策略的执行、包过滤、规定的拦截、 UE的 IP ( Internet Protocol, 因特网协议)地址的分配、 计费功能、 包再现等。
UE、 eNB与核心网之间的控制信令通过 MME进行处理; 用户数据通过 S-GW传输到 P-GW, 然后由 P-GW传输到外部的各类 APN ( Access Point Name, 接入点名称)节点。 由于减少了控制信令与用户数据的耦合, 当新业 务出现只需对负责用户面承载的网元进行升级, 而不会对控制信息传输造成 影响, 从而极大地降低了网络维护的复杂度和设备升级成本。
下面对控制面的信令流程进行分析。
图 2 为连接建立过程中的信令流程示意图, 如图所示, LTE系统中处于 空闲 (idle )状态的 UE, 如果有数据向网络侧发送时, 连接建立过程中的信 令流程如下:
步骤 201、 当 UE有数据需要发送时, 首先根据系统配置的随机接入资源 信息, 等待 RACH ( Random Access Channel, 随机接入信道)调度周期, 选 择一个 preamble (前导码 )后向 eNB发送 Msgl (消息 1 )。
步骤 202-步骤 204、 eNB在接收到 UE发送的 preamble (即 Msgl )后,
在随机接入响应窗中对 UE发送随机接入响应消息 (Msg2, 消息 2 )。 一条随 机接入响应消息( Msg2 )可以对多个 UE的随机接入请求( preamble )进行响 应。
Msg2由 RA-RNTI (随机接入 -RNTI; RA: Random Access , 随机接入; RNTI: Radio Network Temporary Identity, 无线网络临时识别)加扰的 DCI ( Downlink Control Information, 下行控制信息)进行调度, RA-RNTI由发送 Msgl 的时频资源位置确定。 Msg2 中的内容包括: backoff (回退)参数、 与 Msgl对应的 preamble标识、 上行传输 TA ( Timing Alignment, 定时调整量)、 Msg3分配的上行资源(Msg3调度信息)、临时 C-RNTI (小区 -RNTI; C: Cell, 小区)。 backoff参数用于指示如果本次随机接入失败, UE下次发起随机接入 的时延均值。 UE通过 RA-RNTI和 Msg2中的 preamble标识确定发送给自己 的随机接入响应, 如果 Msg2中的 preamble标识对应的 preamble中包含有自 己发起随机接入时的 preamble , 那么认为自己成功接收到随机接入响应消息, 后续将向网络侧发送 Msg3。 如果 UE没有正确接收到 Msg2, 则依据 backoff 参数的时延限制确定发起下一次随机接入的时延, 另外选择随机接入资源发 起下一次随机接入。 达到最大随机接入次数后, UE MAC ( Media Access Control, 媒体接入控制)层向 RRC ( Radio Resource Control, 无线资源控制) 层上报随机接入问题。
步骤 205、 UE在接收到 Msg2后,在 Msg2分配的上行资源上发送 Msg3。 针对不同的场景, Msg3 中包含不同的内容。 在初始接入时, Msg3 中携 带 RRC层生成的 RRC连接建立请求消息。
步骤 206-步骤 208、 eNB和 UE通过 Msg4完成最终的竟争解决。 Msg4 内容与 Msg3的内容相对应的。 初始接入时, Msg4中携带 UE竟争解决标识 MAC层控制单元 ( Contention Resolution Identity MAC CE ), 这个 MAC CE中 包含 UE在 Msg3中传输的 CCCH ( Common Control Channel, 公共控制信道) SDU ( Service Data Unit, 业务数据单元), UE在接收到该 MAC CE后, 与自 身 RRC层信息比较, 以完成竟争解决。 另外, Msg4中可以包含 RRC连接建
立消息, 用于建立 UE的 SRB1 ( Signalling Radio Bearerl , 信令无线承载 1 )。 步骤 209-步骤 210、 UE在竟争解决完成后, 根据 RRC连接建立消息中 的信息建立信令无线承载 1 ( SRB1 ), 并向网络发送 RRC连接建立完成消息。 NAS业务请求消息可以在发送 RRC连接建立完成消息时向网络侧携带发送。
步骤 211-步骤 215、 eNB在接收到 RRC连接建立完成消息后, 将携带的 NAS业务请求消息发送给 MME, 用于请求 MME建立 UE对应的 eNB与核 心网网元间的相关连接 (与 MME的控制面连接和与 S-GW的 S1接口承载)。
MME将 UE对应连接的信息通知 eNB。
步骤 216-步骤 217、 eNB向 UE发送 SMC ( Security Mode Command, 安 全模式命令)和 RRC连接重配消息。用于激活 UE的安全性和为 UE建立 DRB ( Data Radio Bearer, 数据无线承载)和其他信令无线承载( SBR2 )。
需要指出的是安全模式命令 ( SMC )和 RRC连接重配可以在一条 RRC 消息中发送, 也可以分别发送。
步骤 218、 在安全性激活和 DRB、 SRB2配置完成后, UE向网络侧发送 安全模式完成消息和 RRC连接重配完成消息。
这时, UE的用户面数据由 DRB、 SI承载, 通过 eNB、 S-GW发送给核 心网; UE与核心网的控制信令通过 SRB和 eNB与 MME之间的控制面连接 发送给 MME。
对于 detach (去附着 )状态的 UE, 当 UE需要向网络侧发送数据时, UE 需要先发起 attach (附着)过程, 附着到网络, 另外, 为确定用户的合法性还 需要通过鉴权过程进程进行确认。 信令流程相对对于图 2 中所示过程将更为 复杂, 这里不进行详细描述, 可以参见相关协议中的描述。
尽管在 MTC中, MTC终端的数量将大大超出传统通信终端的数量, 但 是, 在许多 MTC的应用场景中, 每次上报的数据量并不是很大(通常为几十 到几百字节), 一个或几个子帧便可传输完成。 然而, MTC 终端为了发送这 些数据,按照当前的数据发送方式也需要通过上述的信令流程建立起 DRB后 , 才能通过 DRB、 SI承载将数据发送给网络侧。从上面的信令过程中可以看出,
传输小数据量所需要的信令开销相对将非常大, 从而严重降低系统效率。 为 此, 小数据量用户面信息传输除了釆用传统的通过建立 DRB、 SI承载来传输 的方式外, 还可以釆用控制面传输用户小数据量数据信息的方式进行传输, 如直接将要发送的小数据量数据直接携带在 RRC信令 (如: 连接建立请求或 RRC连接建立完成消息) 中发送给 eNB, 通过控制面连接发送给核心网, 从 而, 可以降低发送小数据量信息所需的信令消耗, 以及空口资源的占用。
釆用控制面传输用户小数据量数据可以提高系统效率, 但是这种方式也 会增加控制面传输的负荷。 当系统负荷较大时, 釆用控制面传输用户小数据 量数据的方式, 将可能造成或加重控制面传输和 /或处理的拥塞, 如 eNB的信 令处理拥塞、 eNB与 MME连接的信令传输拥塞。 由于一个 MME可以连接多 个 eNB,因此当多个 eNB的控制面信令发送给 MME处理时还可能造成 MME 的信令处理拥塞。
鉴于此, 一方面为了能够利用控制面传输用户数据方式传输小数据量数 据提高系统效率; 另一方面, 为了避免完全釆用控制面传输用户数据方式传 输小数据量数据时可能造成或加重信令传输和 /或处理拥塞, 本发明实施例中 将提出数据传输方式的方案, 由网络侧发送釆用控制面传输用户数据方式传 输小数据量数据的相关指示信息,指示 MTC设备是否能够釆用控制面传输用 户数据的方式发送小数据量数据,从而提高 LTE系统支持机器类通信的性能。 下面结合附图对本发明的具体实施方式进行说明。
在说明过程中, 将首先分别从 MTC设备与网络侧的实施进行说明, 然后 会对二者的配合实施进行说明, 但这并不意味着二者必须配合实施, 实际上, 当 MTC设备与网络侧分开实施时, 其也各自解决 MTC设备侧、 网络侧的问 题, 只是二者结合使用时, 会获得更好的技术效果。
