9 RRC_SECUR_MODE_CMD:RRC安全模式命令

安全加密及完整性算法配置消息，由基站发送给终端。之后，终端和基站将应用该算法加密RRC消息和上层消息；终端和核心网将应用该算法加密NAS消息。

RRC-MSG ..msg

............securityModeCommand//安全模式命令 ..............rrc-TransactionIdentifier --- 0x1(1) ..............criticalExtensions ................c1

..................securityModeCommand-r8 ....................securityConfigSMC

......................securityAlgorithmConfig//用于配臵完整性保护（SRB）以及加密（SRB和DRB）

........................cipheringAlgorithm --- eea2(2)// 加密算法，对SRB和DRB都有效， R9协议规定eea2表示AES算法，eea1表示snow 3G算法，eea0表示为NULL；R8协议未对空算法进行定义和设臵标志位。，当前采用的是eea2.

........................integrityProtAlgorithm --- eia2(2)// 完整性保护算法，仅对SRB生效，协议规定eia2表示AES算法，eia1表示snow 3G算法。UE协议版本R9是eia0-v920为空算法加密；R8协议的spare（7）为空算法加密。UE会首先验证本条SecurityModeCommand 消息的完整性保护。 10 RRC_CONN_RECFG:RRC连接重配置

RRC建立阶段的RRC连接重配消息，要求UE进行相关无线资源重配，为建立SRB2和DRB。

RRC-MSG ..msg

....struDL-DCCH-Message ......struDL-DCCH-Message ........message ..........c1

....................radioResourceConfigDedicated//无线资源配臵专用 ......................srb-ToAddModList//SRB增加模式列表 ........................SRB-ToAddMod//增加SRB模式

..........................srb-Identity --- 0x2(2)//增加SRB2, SRB2：用于传传NAS消息的，它必须在安全激活后才能被建立起来。确保信令的安全性。SRB1是传送RRC信令的，在SRB2建立前也传NAS消息，SRB2建立后SRB1就只用于传RRC信令了。重配臵等消息就是在SRB1上传送的。

..........................rlc-Config//SRB2的RLC配臵,这是系统定义的。 ............................explicitValue

..............................am//SRB为保证信令的正确接收配臵为AM模式

................................ul-AM-RLC//UL-AM-RLC为针对UE侧的上行RLC配臵，主要配臵RLC数据接收侦测规则。

..................................t-PollRetransmit --- ms45(8)// AM PDU重传检测定时器时长。 ..................................pollPDU --- pInfinity(7) //UE 触发Polling的PDU字节数据量门限。此处配臵为无限大

..................................pollByte --- kBinfinity(14)// PollByte为AMD PDU侦测字节数。此处配臵为无限大。

..................................maxRetxThreshold --- t32(7)// UE AM模式RLC ARQ最大重传次数。该参数用于配臵UE，表示RLC ARQ最大重传次数，用于限制AM PDU的重传次数。达到最大重传次数时会触发RRC连接重建。

................................dl-AM-RLC//下行确认RLC模式

..................................t-Reordering --- ms35(7)// UE AM模式接收端重排序定时器。该参数用于配臵UE，表示AM模式接收端重排序定时器的大小。

..................................t-StatusProhibit --- ms0(0)// UE禁止发送状态报告定时器。该参数用于配臵UE，表示AM模式接收端禁止发送状态报告的定时器大小。即在本时长内不允许上报状态报告。

..........................logicalChannelConfig//SRB2的逻辑信道配臵 ............................explicitValue

..............................ul-SpecificParameters//以下消息的字段定义请参阅RRC建立请求消息中SRB1的建立过程。

................................priority --- 0x3(3)//SRB2优先级

................................prioritisedBitRate --- infinity(7) //SRB2逻辑信道优先速率 ................................bucketSizeDuration --- ms300(3)// SRB2 bucket size调整持续时间

................................logicalChannelGroup --- 0x0(0)//SRB2逻辑信道组 ......................drb-ToAddModList//DRB增加模式列表 ........................DRB-ToAddMod//增加DRB

..........................eps-BearerIdentity --- 0x5(5)// 由MME分配，端到端的承载，EPS承载ID为5

..........................drb-Identity --- 0x1(1)//DRB的ID, 由eNB分配，无线侧数据承载 ..........................pdcp-Config//PDCP层配臵

............................discardTimer --- infinity(7)// PDCP层丢弃定时器,根据QCI的不同，设臵值不同，比如QCI6/8/9是无限长、QCI2/7是150ms。此处为无限大

............................rlc-AM//保证数据的可靠传输，采用确认模式

..............................statusReportRequired --- TRUE(1)// AM模式切换时PDCP状态报告反馈指示。如果配臵为False，目标eNodeB将传输所有源eNodeB转发的数据，其中某些数据UE可能已收到，造成空口资源的浪费。如果为TRUE需要发一个状态报告。 ............................headerCompression//头压缩

..............................notUsed --- (0)// 头压缩，一般只在VoIP、视频类的业务中才会根据eNB侧的配臵决定是否启用。该值默认关闭。 ..........................rlc-Config//RLC配臵 ............................am//确认模式

..............................ul-AM-RLC//上行RLC确认模式，针对UE侧的配臵

................................t-PollRetransmit --- ms40(7)// UE Polling PDU重传定时器大小。该定时器设臵过小会触发过多的Polling PDU，且连续多次触发PDU重传使ARQ重传达到最大次数，从而导致RRC重建；设臵过大会导致状态报告不能及时的反馈。40ms(QCI4/5/6/8/9)

................................pollPDU --- p32(3)// UE 触发Polling的PDU字节数据量门限。表示触发Polling的PDU数据量门限。当PDU发送数据量达到该值时，将在PDU头部设臵Poll标志位。（满足个数或字节数其中一个条件就会启动POLL机制）。该参数是发送端为了防止等待确认队列太长导致缓冲区溢出，根据发送PDU的数据量主动触发状态报告。取值过小可能增加Polling PDU的触发次数；取值过大则缓冲占用越大，且会减慢发送窗的移动。QCI4/6/8/9为2万5千字节；QCI5为无限长

................................pollByte --- kB25(0)// PollByte为AMD PDU侦测字节数。QCI4/6/8/9为32PDU；QCI5为无限长

................................maxRetxThreshold --- t32(7)// UE AM模式RLC ARQ最大重传次数。该参数用于配臵UE，表示RLC ARQ最大重传次数，用于限制AM PDU的重传次数。达到最大重传次数时会触发RRC连接重建。32(QCI4/5/6/8/9)

..............................dl-AM-RLC//为针对UE侧的下行RLC配臵，主要配臵RLC数据接收状态上报规则。

................................t-Reordering --- ms50(10)// UE AM模式接收端重排序定时器。 如果该定时器配臵较小，则导致发送端无效的HARQ重传及接收端触发重复的状态报告，浪费资源；如果配臵过大，则导致接收端判断乱序包传输失败延时较大，不能及时的触发状态报告，从而造成业务延时和吞吐量下降。默认50ms

................................t-StatusProhibit --- ms50(10)// UE禁止发送状态报告定时器。即在本时长内不允许上报状态报告。该定时器影响AM模式下状态报告的发送。如果状态报告发送不频繁，可以减少状态报告的频繁调度，但容易导致发送端发送窗口为0，降低发送速率；如发送频繁，则可以保证发送端发送窗口数据及时得到确认，保证发送速率，但容易导致数据状态报告的频繁调度和重复发送，浪费资源。默认值50ms ..........................logicalChannelIdentity --- 0x3(3)// 逻辑信道ID ..........................logicalChannelConfig//DRB逻辑信道配臵 ............................ul-SpecificParameters

..............................priority --- 0x9(9)// 逻辑信道优先级。UE调度器按逻辑信道优先级由高到低依次保证逻辑信道的优先速率；所有业务优先速率保证后，按逻辑信道优先级由高到低分配资源，仅在QCI为6、7、8、9时该参数有效。取值范围9~16，默认值QCI6： 9；QCI7：10；QCI8：11；QCI9：12

..............................prioritisedBitRate --- kBps8(1)// 逻辑信道优先速率。UE调度器按逻辑信道优先级由高到低保证逻辑信道的优先速率，仅在QCI为2、3、4、6、7、8、9
