Abstract

Embodiments of the present invention provide a bearer establishment method, a base station and a user equipment (UE). The method comprises: sending a mixed message to a base station, the mixed message comprising a Radio Resource Control (RRC) connection request and a service request; resending the mixed message to the base station if a contention resolution clock at a Media Access Control (MAC) layer times out and a first count value is smaller than the maximum number of retransmissions of the mixed message; sending a common message to the base station if the contention resolution clock at the MAC layer times out and the first count value is larger than or equal to the maximum number of retransmissions of the mixed message, the common message comprising the RRC connection request but excluding the service request, and the first count value being the number of times the mixed message is sent to the base station. Therefore, when the parallel operation mode of the UE fails, the serial operation mode can be rolled back to, thereby efficiently ensuring the compatibility between a parallel operation and a serial operation and increasing the success rate of bearer establishment.

Description

承载建立方法、 基站和用户设备 技术领域  Bearer establishment method, base station and user equipment
本发明实施例涉及通信技术领域， 并且更具体地， 涉及^载建立方法、 基站和用户设备。 背景技术  The embodiments of the present invention relate to the field of communications technologies, and more specifically, to a method for establishing a base, a base station, and a user equipment. Background technique
随着通信网络技术的发展， M2M ( Machine to Machine, 机器对机器） 通信逐渐成为主流通信技术， 具有巨大的市场潜力。 M2M技术是通信和信 息技术的整合， 可以用于双向通信。  With the development of communication network technology, M2M (Machine to Machine) communication has gradually become the mainstream communication technology, with huge market potential. M2M technology is an integration of communication and information technology that can be used for two-way communication.
典型的 M2M网络结构包括 M2M终端、 M2M网络和 MTC( Machine Type Communication, 机器类型通信）服务器。 M2M终端可以是各种有线的或者 无线的通信终端设备， 用于数据采集、 环境监控、 设备维护或设备升级等。 例如， 采集居民家庭消耗的电量或煤气量等， 这样就避免人工上门抄表的繁 瑣工作。 又例如， 在环境检测中， 水污染警告或山体滑坡监控等。 M2M 网 络可以是各种有线网络， 如 Internet或 Intranet等， 也可以是各种无线网络， 如 GSM ( Global System of Mobile communication, 全球移动通信***）、 CDMA ( Code Division Multiple Access,码分多址）、 UMTS ( Universal Mobile Telecommunications System,通用移动通信*** )、 LTE( Long Term Evolution, 长期演进 )或 WiMax ( Worldwide Interoperability for Microwave Access, 全 球微波互联接入）等蜂窝通信网络， 或者 Zigbee或 Wifi ( Wireless Fidelity, 无线保真）等短距离通信网络。 MTC服务器处于监控中心的位置， 用于周 期性收集各个终端上报的数据， 并给出分析结果和触发 M2M终端升级等。 另外， 存在其他类型的 M2M网络结构， 如用于智能交通的汽车与汽车之间 通信、 交通事故紧急告警或路面指示等技术。  A typical M2M network structure includes an M2M terminal, an M2M network, and an MTC (Machine Type Communication) server. The M2M terminal can be a variety of wired or wireless communication terminal equipment for data acquisition, environmental monitoring, equipment maintenance or equipment upgrade. For example, collecting the amount of electricity or gas consumed by households, etc., thus avoiding the cumbersome work of manual door-to-door meter reading. For example, in environmental testing, water pollution warning or landslide monitoring. The M2M network can be a variety of wired networks, such as the Internet or an intranet, or various wireless networks, such as GSM (Global System of Mobile communication), CDMA (Code Division Multiple Access). , UMTS (Universal Mobile Telecommunications System), LTE (Long Term Evolution) or WiMax ( Worldwide Interoperability for Microwave Access) cellular communication networks, or Zigbee or Wifi (Wireless Fidelity) , wireless fidelity) and other short-range communication networks. The MTC server is located in the monitoring center and is used to periodically collect data reported by each terminal, and provide analysis results and trigger M2M terminal upgrades. In addition, there are other types of M2M network structures, such as communication between cars and cars for intelligent transportation, traffic accident emergency warnings or road indications.
M2M 业务具有终端数量多、 每次传输的数据量小和业务呈现一定的周 期性等特点。 例如， 智能抄表类的 M2M业务在蜂窝网的一个小区就可能多 达 30000个终端， 每次上报的数据包大小不足 50字节， 同时， 业务周期特 性明显， 终端会每小时、 每天、 每周或者每月上报一次数据。  The M2M service has many features such as a large number of terminals, a small amount of data transmitted each time, and a certain periodicity of the service. For example, the M2M service of the smart meter reading class may have up to 30,000 terminals in one cell of the cellular network, and the reported packet size is less than 50 bytes each time. At the same time, the service cycle characteristics are obvious, and the terminal will be hourly, daily, and every time. Report data once a week or monthly.
现有的网络设计通常是针对 H2H ( Human to Human, 人对人）通信的 业务。 例如， 蜂窝通信网络中人与人之间的语音电话业务或文件传输等。 但 是，针对 H2H通信设计的网络在面对 M2M业务时会存在大量的不足。例如， 为了传输 M2M业务不足 50字节的数据包，UE需要分别执行以下多个步骤： 向网络侧发起 RRC(Radio Resource Control, RRC)连接建立请求和业务请求、 建立 SRB( Signaling Radio Bearer,信令无线承载 )和 DRB( Data Radio Bearer, 数据无线承载 ), 接收网络侧发送的 RRC连接重配置消息， 处理 RRC连接 重配置， 向网络侧发送 RRC连接重配置完成消息， 向网络侧发送业务完成 消息等。 因此， 采用现有技术实现 M2M业务的网络信令交互次数多， 导致 网络传输效率低。 又例如， 为了增加并行性 UE同时发送请求消息 （即同时 向网络侧发送 RRC连接建立请求和业务请求）导致网络覆盖性变弱， 接入 失败概率升高， 极端情况下可能会令 UE无法接入网络， 因此若在网络覆盖 状况与网络工作的并行方式上做一定的折中会有效满足网络利用效率的同 时保证网络的覆盖状况。 发明内容 Existing network designs are typically for H2H (Human to Human) communications. For example, voice telephony services or file transfers between people in a cellular communication network. but Yes, the network designed for H2H communication will have a lot of deficiencies in the face of M2M services. For example, in order to transmit a data packet with an M2M service of less than 50 bytes, the UE needs to perform the following multiple steps: Initiating an RRC (Radio Resource Control, RRC) connection establishment request and a service request to the network side, and establishing an SRB (Signaling Radio Bearer) The radio bearer and the DRB (Data Radio Bearer) receive the RRC connection reconfiguration message sent by the network side, process the RRC connection reconfiguration, and send an RRC connection reconfiguration complete message to the network side, and send the service completion to the network side. Messages, etc. Therefore, the number of network signaling interactions of the M2M service implemented by the prior art is high, resulting in low network transmission efficiency. For example, in order to increase the parallelism, the UE simultaneously sends a request message (ie, sends an RRC connection setup request and a service request to the network side at the same time), causing network coverage to be weak, and the probability of access failure is increased. In an extreme case, the UE may not be able to connect. Into the network, so if the network coverage and the network work in parallel, make a certain compromise will effectively meet the network utilization efficiency while ensuring network coverage.

101 , 向基站发送混合消息， 混合消息包括 RRC连接请求和业务请求。 101. Send a hybrid message to a base station, where the hybrid message includes an RRC connection request and a service request.
102,如果媒体接入控制 MAC层竟争解决时钟超时且第一计数值小于混 合消息的最大重传次数， 则重新向基站发送混合消息。 102. If the media access control MAC layer competes to resolve the clock timeout and the first count value is less than the maximum number of retransmissions of the mixed message, the hybrid message is resent to the base station.
103,如果 MAC层竟争解决时钟超时且第一计数值大于或等于混合消息 的最大重传次数， 则向基站发送普通消息， 普通消息包括 RRC连接请求且 不包括业务请求， 第一计数值为已向基站发送混合消息的次数。  103. If the MAC layer competes to resolve the clock timeout and the first count value is greater than or equal to the maximum number of retransmissions of the hybrid message, send a normal message to the base station, where the normal message includes the RRC connection request and does not include the service request, and the first count value is The number of times a mixed message has been sent to the base station.
其中， RRC ( Radio Resource Control, 无线资源控制）连接请求包括 TMSI ( Temporary Mobile Subscriber Identity, 临时移动用户标识）、 RRC连 接建立的原因。 TMSI用于在核心网唯一地标识 UE, 如***架构演进-临时 移动用户标识 S-TMSI。 RRC连接建立的原因用于指明 UE发起 RRC连接建 立的原因。 例如， 响应呼叫或发起主叫等。 可选地， M2M 业务也可以作为 RRC连接建立的原因。 业务请求 (Service Request)是一条 NAS ( Non- Access Stratum, 非接入层消息）， 包括用于识别 UE和对 UE进行安全鉴权的参数。 例如， 协议鉴别、 安全头、 KSI ( Key Set Identifier, 密钥集标识）或短消息 认证码等。 应理解， 本发明实施例对此并不限定。  The RRC (Radio Resource Control) connection request includes a TMSI (Temporary Mobile Subscriber Identity) and a reason for the RRC connection establishment. The TMSI is used to uniquely identify the UE in the core network, such as the System Architecture Evolution - Temporary Mobile Subscriber Identity S-TMSI. The reason for the establishment of the RRC connection is to indicate the reason why the UE initiates the establishment of the RRC connection. For example, responding to a call or initiating a caller, etc. Optionally, the M2M service can also be used as the cause of the RRC connection establishment. A service request (Service Request) is a NAS (Non-Access Stratum, non-access stratum message), and includes parameters for identifying a UE and performing security authentication on the UE. For example, protocol authentication, security header, KSI (Key Set Identifier) or short message authentication code. It should be understood that the embodiments of the present invention are not limited thereto.
本发明实施例中， 用户设备向基站发送混合消息， 在混合消息中不仅包 括 RRC连接请求和业务请求，当媒体接入控制 MAC层竟争解决时钟超时且 已向基站发送混合消息的次数大于或等于混合消息的最大重传次数时， 向基 站发送普通消息， 该普通消息包括 RRC连接请求且不包括业务请求。 因此， 当 UE并行操作模式失败时可以回退到串行操作模式， 这样， 有效地保证与 并行操作和串行操作的兼容性， 能够提高承载建立的成功率。  In the embodiment of the present invention, the user equipment sends a hybrid message to the base station, where the mixed message includes not only the RRC connection request and the service request, but the media access control MAC layer competes to resolve the clock timeout and has sent the mixed message to the base station more than or When it is equal to the maximum number of retransmissions of the hybrid message, the normal message is sent to the base station, and the normal message includes the RRC connection request and does not include the service request. Therefore, when the UE parallel operation mode fails, it can fall back to the serial operation mode, thus effectively ensuring compatibility with parallel operation and serial operation, and the success rate of bearer establishment can be improved.
可选地， 作为一个实施例， RRC连接请求还可以包括 UE选择的 PLMN ( Public Land Mobile Network, 公共陆地移动网络）， 具体地， 在接入网被多 个 PLMN共享的情况下， RRC连接请求包括 UE选择的 PLMN, 以指明 UE在哪个 PLMN工作。  Optionally, as an embodiment, the RRC connection request may further include a PLMN (Public Land Mobile Network) selected by the UE. Specifically, if the access network is shared by multiple PLMNs, the RRC connection request is performed. The PLMN selected by the UE is included to indicate which PLMN the UE is working on.
可选地， 作为另一个实施例， 在步骤 101之前， UE可以确定混合消息 的最大重传次数。 例如， UE可以预先设置混合消息的最大重传次数。 或者， UE可以接收基站通知的混合消息的最大重传次数。 应理解， 本发明实施例 对于混合消息的最大重传次数的确定方式及混合消息的最大重传次数取值 并不限定。 可选地， 作为另一个实施例， 在步骤 103之后， 如果 MAC层竟争解决 时钟超时且第二计数值小于普通消息的最大重传次数， 则重新向基站发送普 通消息。 其中， 第二计数值为已向基站发送普通消息的次数， 或者第二计数 值为混合消息的最大重传次数加上已向基站发送普通消息的次数且混合消 息的最大重传次数 d、于普通消息的最大重传次数。 Optionally, as another embodiment, before step 101, the UE may determine the maximum number of retransmissions of the hybrid message. For example, the UE may preset the maximum number of retransmissions of the mixed message. Alternatively, the UE may receive the maximum number of retransmissions of the mixed message notified by the base station. It should be understood that the method for determining the maximum number of retransmissions of the mixed message and the maximum number of retransmissions of the mixed message in the embodiment of the present invention are not limited. Optionally, as another embodiment, after step 103, if the MAC layer competes to resolve the clock timeout and the second count value is less than the maximum number of retransmissions of the normal message, the normal message is resent to the base station. The second count value is the number of times the normal message has been sent to the base station, or the second count value is the maximum number of retransmissions of the mixed message plus the number of times the ordinary message has been sent to the base station and the maximum number of retransmissions of the mixed message is d. The maximum number of retransmissions of ordinary messages.
以 LTE***为例， 混合消息是 LTE***承载建立过程中并行操作模式 的消息 3 ( Msg3 ), 称为 "混合 Msg3" , 即混合 Msg3包括 RRC连接请求和 业务请求； 普通消息是 LTE***承载建立过程中串行操作模式的 Msg3, 称 为 "普通 Msg3" , 即普通消息包括 RRC连接请求且不包括业务请求。 假设 混合 Msg3的最大重传次数为 maxHARQ-HybridMsg3Tx, 普通 Msg3的最大 重传次数为 maxHARQ-Msg3Tx。 如果 MAC层竟争解决时钟超时， UE已向 基站发送混合 Msg3的次数为 maxHARQ-HybridMsg3Tx, 则 UE向基站发送 普通 Msg3。 在一种实现方式下， 向基站发送普通 Msg3并将重传次数的计 数值清零， 称为 "独立传输模式"。 在另一种实现方式下， 向基站发送普通 Msg3 而重传次数的计数值不清零， 即当前的重传次数的计数值为 maxHARQ-HybridMsg3Tx , 称为 "混合传输模式"， 混合传输模式下的 maxHARQ-HybridMsg3Tx小于 maxHARQ-Msg3Tx。  Taking the LTE system as an example, the hybrid message is the message 3 (Msg3) of the parallel operation mode in the bearer establishment process of the LTE system, which is called "hybrid Msg3", that is, the hybrid Msg3 includes the RRC connection request and the service request; the common message is the LTE system bearer establishment. The Msg3 of the serial operation mode in the process is called "normal Msg3", that is, the normal message includes the RRC connection request and does not include the service request. Assume that the maximum number of retransmissions of the mixed Msg3 is maxHARQ-HybridMsg3Tx, and the maximum number of retransmissions of the normal Msg3 is maxHARQ-Msg3Tx. If the MAC layer competes to resolve the clock timeout and the number of times the UE has sent the hybrid Msg3 to the base station is maxHARQ-HybridMsg3Tx, the UE sends the normal Msg3 to the base station. In one implementation, the normal Msg3 is sent to the base station and the count value of the number of retransmissions is cleared to zero, which is called "independent transmission mode". In another implementation manner, the normal Msg3 is sent to the base station, and the count value of the number of retransmissions is not cleared, that is, the current retransmission count has a count value of maxHARQ-HybridMsg3Tx, which is called "hybrid transmission mode", in the hybrid transmission mode. The maxHARQ-HybridMsg3Tx is smaller than maxHARQ-Msg3Tx.
下面结合例子详细描述承载建立方法的非限制性的实施方式。  A non-limiting embodiment of the bearer establishment method will be described in detail below with reference to examples.
图 2是本发明一个实施例的承载建立方法的过程的示意性流程图。为了 描述方便， 下述实施例以 LTE***为例进行说明。 应理解， 本发明实施例并 不限于此， 可以为 LTE***之外的其它移动通信***。  FIG. 2 is a schematic flowchart of a process of a bearer establishment method according to an embodiment of the present invention. For convenience of description, the following embodiments are described by taking an LTE system as an example. It should be understood that the embodiments of the present invention are not limited thereto, and may be other mobile communication systems than the LTE system.
201 , eNB向 UE通知混合 Msg3的最大重传次数。  201. The eNB notifies the UE of the maximum number of retransmissions of the hybrid Msg3.
例如， eNB可以通过网络广播的形式发送混合 Msg3的最大重传次数的 信息， 该混合 Msg3的最大重传次数为 maxHARQ-HybridMsg3Tx。 应理解， 本发明实施例对于 eNB通知 UE混合 Msg3的最大重传次数的方式并不限定。  For example, the eNB may send the information of the maximum number of retransmissions of the hybrid Msg3 in the form of a network broadcast, and the maximum number of retransmissions of the hybrid Msg3 is maxHARQ-HybridMsg3Tx. It should be understood that the manner in which the eNB informs the UE of the maximum number of retransmissions of the Msg3 is not limited.
202, UE向 eNB发送随机接入前导。  202. The UE sends a random access preamble to the eNB.
例如， UE在接入网络时， 从网络提供的候选随机接入前导中选择一个 发送给 eNB。  For example, when the UE accesses the network, one of the candidate random access preambles provided by the network is selected and sent to the eNB.
203 , eNB向 UE发送随机接入前导响应。  203. The eNB sends a random access preamble response to the UE.
eNB检测到 UE的随机接入前导时返回一个随机接入响应， 此时， 网络 侧设备还不能识别是哪个 UE发送的随机接入前导。 204, UE向 eNB发送混合 Msg3。 When the eNB detects the random access preamble of the UE, the eNB returns a random access response. At this time, the network side device cannot identify which UE is transmitting the random access preamble. 204. The UE sends the hybrid Msg3 to the eNB.
混合 Msg3 包括无线资源控制 RRC连接请求和业务请求。 其中， RRC 连接请求包括 S-TMSI和 RRC连接建立的原因。 S-TMSI用于在核心网唯一 地标识 UE。 RRC连接建立的原因用于指明 UE发起 RRC连接建立的原因。 例如， 响应呼叫或发起主叫等。 可选地， M2M业务也可以作为 RRC连接建 立的原因。 业务请求是一条 NAS, 包括用于识别 UE和对 UE进行安全鉴权 的参数。 例如， 协议鉴别、 安全头、 KSI 或短消息认证码 等。 应理解， 本 发明实施例对此并不限定。  Hybrid Msg3 includes radio resource control RRC connection requests and service requests. The RRC connection request includes the reason for the establishment of the S-TMSI and the RRC connection. The S-TMSI is used to uniquely identify the UE in the core network. The reason for the establishment of the RRC connection is to indicate the reason why the UE initiates the establishment of the RRC connection. For example, responding to a call or initiating a caller, etc. Optionally, the M2M service can also be established as an RRC connection. The service request is a NAS, including parameters for identifying the UE and performing security authentication on the UE. For example, protocol authentication, security headers, KSI or short message authentication codes, and so on. It should be understood that the embodiments of the present invention are not limited thereto.
例如， RRC连接请求还可以包括 UE选择的 PLMN, 具体地， 在接入网 被多个 PLMN共享的情况下， RRC连接请求包括 UE选择的 PLMN, 以指 明 UE在哪个 PLMN工作。  For example, the RRC connection request may further include a PLMN selected by the UE. Specifically, if the access network is shared by multiple PLMNs, the RRC connection request includes the PLMN selected by the UE to indicate which PLMN the UE is working on.
205 , MAC层竟争解决时钟超时且第一计数值小于混合 Msg3的最大重 传次数。  205. The MAC layer competes to resolve the clock timeout and the first count value is less than the maximum number of retransmissions of the mixed Msg3.
206, UE重新向 eNB发送混合 Msg3。  206. The UE resends the hybrid Msg3 to the eNB.
例如，第一计数值可以为 UE已向 eNB发送混合 Msg3的次数。当 MAC 层竟争解决时钟超时且第一计数值小于 maxHARQ-HybridMsg3Tx时， UE执 行步骤 206。  For example, the first count value may be the number of times the UE has sent the hybrid Msg3 to the eNB. When the MAC layer contends to resolve the clock timeout and the first count value is less than maxHARQ-HybridMsg3Tx, the UE performs step 206.
207, MAC层竟争解决时钟超时且第一计数值等于或大于混合 Msg3的 最大重传次数。  207. The MAC layer competes to resolve the clock timeout and the first count value is equal to or greater than the maximum number of retransmissions of the mixed Msg3.
208, UE向 eNB发送普通 Msg3。  208. The UE sends a normal Msg3 to the eNB.
例如， 当 MAC 层竟争解决时钟超时且第一计数值大于或等于 maxHARQ-HybridMsg3T时， UE向 eNB发送普通 Msg3。 在一种实现方式 下， UE可以执行独立传输模式， 即向 eNB发送普通 Msg3并将重传次数的 计数值清零。 在另一种实现方式下， UE可以执行混合传输模式， 即向 eNB 发送普通 Msg3 而重传次数的计数值不清零， 在混合传输模式下， maxHARQ-HybridMsg3Tx 小 于 普 通 Msg3 的 最 大 重 传 次 数 maxHARQ-Msg3Tx。  For example, when the MAC layer competes to resolve the clock timeout and the first count value is greater than or equal to maxHARQ-HybridMsg3T, the UE sends the normal Msg3 to the eNB. In an implementation manner, the UE may perform an independent transmission mode, that is, send the normal Msg3 to the eNB and clear the count value of the number of retransmissions. In another implementation manner, the UE may perform a hybrid transmission mode, that is, send the normal Msg3 to the eNB, and the count value of the retransmission times is not cleared. In the hybrid transmission mode, the maxHARQ-HybridMsg3Tx is smaller than the maximum retransmission number of the common Msg3 maxHARQ. -Msg3Tx.
本发明实施例中， UE向 eNB发送混合 Msg3,在混合 Msg3中不仅包括 RRC连接请求和业务请求， 当 MAC层竟争解决时钟超时且已向 eNB发送 混合 Msg3的次数大于或等于混合 Msg3的最大重传次数时， 向 eNB发送普 通 Msg3 ,该普通 Msg3包括 RRC连接请求且不包括业务请求。 因此， 当 UE 并行操作模式失败时可以回退到串行操作模式， 这样， 有效地保证与并行操 作和串行操作的兼容性， 能够提高承载建立的成功率。 In the embodiment of the present invention, the UE sends the hybrid Msg3 to the eNB, and the hybrid Msg3 includes not only the RRC connection request and the service request, but the MAC layer competes to resolve the clock timeout and the number of times the mixed Msg3 has been sent to the eNB is greater than or equal to the maximum of the mixed Msg3. When the number of retransmissions is sent, the normal Msg3 is sent to the eNB, and the normal Msg3 includes an RRC connection request and does not include a service request. Therefore, when the UE When the parallel operation mode fails, it can fall back to the serial operation mode, thus effectively ensuring compatibility with parallel operation and serial operation, and improving the success rate of bearer establishment.

The RRC connection request includes the reason for the S-TMSI and the RRC connection establishment. The S-TMSI is used to uniquely identify the UE in the core network. The reason for the establishment of the RRC connection is to indicate the reason why the UE initiates the establishment of the RRC connection.

The UE establishes the SRB1, SRB2, DRB and security mode of the UE according to the hybrid RRC connection setup message received in step 508.
509 , UE向 eNB发送混合 RRC连接建立完成消息。  509. The UE sends a hybrid RRC connection setup complete message to the eNB.
