Description

一种信令发送方法、系统及装置 A transmission method, system and apparatus for signaling

技术领域 FIELD

[0001] 本发明涉及通信技术领域,尤其涉及一种信令发送方法、系统及装置。 [0001] The present invention relates to communications technologies, and in particular, to a signaling method, system and apparatus.

背景技术 Background technique

[0002] 在先进的长期演进(LTE-A)系统中,第三代合作项目(3GPP,ThirdGenerationPartnership Project)要求从空闲模式(Idle mode)到连接模式(Connected mode)的转换时延要小于50毫秒(ms)。 [0002] In the long term evolution advanced (LTE-A) system, the Third Generation Partnership Project (3GPP, ThirdGenerationPartnership Project) delay required to convert from an idle mode (Idle mode) to the connected mode (Connected mode) must be less than 50 ms (ms). 为了达到这个目标,引入了在随机接入过程中将无线链路控制(RRC)信令和非接入层(NAS,Non-Access Stratum)信令进行合并发送的技术,使得空中接口连接建立和网络侧的连接建立可以同时进行,进而可以节省接入的时延。 To achieve this, the introduction of a random access procedure in a radio link control (RRC) signaling, and the non-access stratum (NAS, Non-Access Stratum) signaling transmission techniques combined, so that the air interface connection setup, and network connection is established may be performed simultaneously, and thus can save access latency. 但是,RRC连接建立请求信令和NAS业务请求信令的合并发送对于处于小区边缘、功率受限或者信道条件不好的用户设备(UE)来讲,其增益是有限的。 However, the RRC connection establishment request signaling and sending the combined NAS service request signaling for the user equipment (UE) in the cell edge, or power limited in terms of poor channel conditions, the gain is limited.

[0003] UE由空闲模式向连接模式转移的过程包括:RRC连接建立过程、安全性激活、无线承载的建立过程。 [0003] The procedure of the UE transfers from the idle mode to the connection mode comprising: RRC connection establishment procedure, the security of the activation process of setting up the radio bearer. 在传统的长期演进(LTE)系统中,UE先发起随机接入过程,通过信息(Msg3)携带RRC连接建立请求消息,先发起演进型基站(eNB)和UE之间的连接建立过程,待连接建立成功后再发送NAS业务请求消息,建立与移动管理实体(MME,MobilityManagement Entity)的连接,激活安全机制,具体流程如图1所示。 In the conventional long term evolution (LTE) system, the first UE initiates the random access procedure, an RRC connection establishment request message carries the information through (the Msg3), to initiate the first evolved base station (eNB) and the UE establishes a connection between the process, be connected successfully established before sending the NAS service request message, to establish a connection with a mobile management entity (MME, MobilityManagement entity), activation of the safety mechanism, the specific process shown in Figure 1.

[0004] 一种减少控制面建立时延的方法是减少握手交互的次数,将RRC连接建立请求消息和NAS业务请求消息进行合并传输是一种可能的方法,使得UE和eNB之间的RRC连接建立过程,与eNB和MME之间的连接建立过程可以同时进行,缩短了时延,具体流程如图2所 [0004] A method of reducing delay in establishing the control plane of the handshake is to reduce the number of interactions, the RRC connection establishment request message and the NAS service request message is transmitted to merge one possible approach, such that RRC connection between the UE and the eNB establishing a connection between the process, the MME and the eNB setup procedure may be performed simultaneously to shorten the delay, the specific process in FIG. 2

/Jn ο / Jn ο

[0005] 具体在随机接入过程中如何实现在Msg3中将RRC连接建立请求消息和NAS业务请求消息进行合并传输,如下所述: [0005] DETAILED how in the Msg3 RRC connection establishment request message and the NAS service request message for combined transport, as described below in the random access procedure:

[0006] 随机接入技术是现代蜂窝移动通信系统的重要功能,在很多场景下,必须首先进行随机接入,才能继续后续的操作。 [0006] To continue, a subsequent random access technology is an important feature of modern cellular mobile communication system, in many scenarios, must first random access. 以LTE系统为例,需要进行随机接入的场景包括以下五种: In the LTE system as an example, the need for random access scenarios include the following five:

[0007] 一、处于待机(RRC-1dle)状态的UE进入连接(RRC-Connected)状态。 [0007] First, UE is in the standby (RRC-1dle) into the connecting state (RRC-Connected) state.

[0008] 二、UE在无线链路建立失败后,恢复与eNB的连接。 [0008] bis, the UE in the radio link setup failure, the recovery connection with the eNB.

[0009] 三、UE有上行数据到达,但eNB没有分配新的上行资源,并且也没有专用的调度请求资源。 [0009] III, the UE has uplink data arrival, the new eNB uplink resource is not allocated, and no dedicated scheduling request resource.

[0010] 四、eNB有下行数据到达,但无法直接调度UE,比如UE目前正处于上行失步状态。 [0010] IV, the eNB has downlink data arrives, the UE is scheduled but not directly, such as UE is currently in the uplink out of synchronization state.

[0011] 五、切换过程。 [0011] Fifth, the handover procedure.

[0012]目前LTE中的随机接入过程分为两种:竞争随机接入和非竞争随机接入。 [0012] In the current LTE random access procedure is divided into two types: contention based random access and non-contention random access.

[0013] 非竞争随机接入由网络侧发起,应用于上述第四种和第五种随机接入场景,即下行数据到达和切换。 [0013] The non-contention random access initiated by the network side, is applied to the above-described fourth and fifth random access scenario, i.e. handover and downlink data arrival.

[0014] 对于UE的初始接入,即由空闲模式进入连接模式,需要发起竞争随机接入,竞争随机接入过程如图3所示,其中Msgl用于发送随机序列(preamble),UE首先按照信息大小、路损等信息选择随机序列组,即组A(gr0Up A)或组B(gr0Up B),然后,在选定的组中随机选择preamble,选择下一个可用的分组随机接入信道(PRACH, Packet Random AccessCHanneI)资源发生的子巾贞进行preamble发送;对于时分双工(TDD)系统,I个子巾贞有多个PRACH资源,在后面连续的3个子帧内随机选择PRACH资源发送preamble。 [0014] For the initial access of the UE, i.e., an idle mode enters the connected mode, required to initiate contention based random access, random access procedure shown in Figure 3, wherein Msgl for transmitting random sequence (Preamble), according to the first UE information size, and so the path loss information selecting random sequence group, i.e. group a (gr0Up a) or group B (gr0Up B), then, in the selected preamble randomly selected group, selecting the next available packet random access channel ( Zhen sub towel PRACH, Packet random AccessCHanneI) in resource preamble is transmitted; for a time division duplex (TDD) systems, I have many sub towel Zhen PRACH resource randomly selected PRACH resource successive transmitted preamble subframe as the back 3. [0015] Msg2与Msgl为半同步的,通过Msg2接收窗实现,所述接收窗是指在发送完Msgl后的一段时间(N毫秒或M个子帧等)内等待接收Msg2,超出这个时间则认为不会收到Msg2,随机接入失败。 [0015] and MSGL Msg2 as semi-synchronous, the receiving window Msg2 achieved, the receive window refers to a period of time waiting to receive Msg2 (N M subframes ms or the like) after completion of the transmission MSGL, beyond this time is considered You will not receive Msg2, random access failure. Msg2的内容包括随机序列标识(RA-Preamble identifier)、时间提前量(TA)、上行链路授权(UL grant)并分配临时小区无线网络标识(Temporary C-RNTI)坐寸ο[0016] 对于初始接入场景,Msg3传输公共控制信道(CCCH)信道上RRC层产生的RRC连接建立请求(RRC Connection Request)消息,使用无线链路控制(RLC)透明模式(TM)。 Msg2 including the random sequence identifier (RA-Preamble identifier), timing advance (TA), uplink grant (UL grant) and a temporary cell radio network identifier assigned (Temporary C-RNTI) sit inch ο [0016] For the initial access scenario, the Msg3 transmission RRC common control channel (CCCH) channel generated by the RRC layer connection establishment request (RRC connection request) message, a radio link control (RLC) transparent mode (TM). [0017] 对于版本IO(R-1O)的UE,希望缩短初始接入的时延,可以将RRCConnectionRequest消息和NAS业务请求(NAS Service Request)消息合并在Msg3中发送。 [0017] For versions IO (R-1O) of the UE, desirable to shorten the delay in initial access can be transmitted in a Msg3 RRCConnectionRequest message and the NAS Service Request (NAS Service Request) message combined. 因此,Msg3承载消息的传输块尺寸变大,对于信道条件较好的UE,可以通过分配更多的上行资源或者使用更高的调制编码方式(MCS)来传输合并后的消息。 Accordingly, bearer message Msg3 transport block size increases, for a better channel conditions the UE, by allocating more resources to the uplink or the use of higher modulation and coding scheme (MCS) transmitting the combined message. 但是,对于功率受限或者信道条件较差的UE,则无法采用合并发送的机制来发送RRC连接建立请求信令和NAS业务请求信令,因此,并不是所有的UE都可以将RRC连接建立请求信令和NAS业务请求信令合并发送给eNB。 However, for a power-limited or poor channel conditions of the UE, the combined transmission mechanism can not be adopted to transmit RRC connection establishment request signaling and NAS service request signaling, and therefore, not all the UE may request an RRC connection establishment signaling and NAS service request and sending the combined signaling to the eNB. [0018] 综上所述,现有技术为了缩短LTE-A UE的接入时延,引入了在随机接入过程中将RRC连接建立请求信令和NAS业务请求信令合并发送的机制,但是现有技术并没有给出UE该如何决定是否采用这种机制来发送RRC连接建立请求信令和NAS业务请求信令,因此如果对所有UE都采用将RRC连接建立请求信令和NAS业务请求信令合并发送的机制,会导致资源利用的不合理,并且有可能引入新的时延。 [0018] In summary, the prior art in order to shorten the LTE-A UE access delay is introduced in a random access procedure the RRC connection establishment request signaling and NAS service request mechanism combined signaling transmitted, but the prior art does not give the UE how to decide whether to use this mechanism to send an RRC connection establishment request signaling and NAS service request signaling, are used so that if the request signaling and NAS service request signal to all the UE RRC connection establishment send a mechanism so that the merger would lead to irrational use of resources, and it is possible to introduce a new delay. 发明内容[0019] 本发明实施例提供了一种信令发送方法、系统及装置,用以实现UE决定是否采用将RRC连接建立请求信令和NAS业务请求信令合并发送的机制,从而有效缩短接入时延,提高资源利用率,避免资源的过多消耗。 SUMMARY [0019] Embodiments provide a signaling method, system and apparatus of the present invention, the UE decides whether to use to achieve an RRC connection establishment request signaling and NAS service request and sending the combined signaling mechanisms, thus effectively shortening access delay, improve resource utilization, avoid excessive consumption of resources.

具体实施方式 detailed description

[0036] 本发明实施例提供了一种信令发送方法、系统及装置,用以实现UE决定是否采用将RRC连接建立请求信令和NAS业务请求信令合并发送的机制,从而有效缩短接入时延,提高资源利用率,避免资源的过多消耗。 Example embodiments provide a signaling method, system and device for realizing the UE decides whether to adopt the RRC connection establishment request signaling mechanism for signaling and NAS service request sent by the merger, thereby effectively shortening the access [0036] the present invention delay, improve resource utilization, avoid excessive consumption of resources.

[0037] 本发明实施例中的UE根据信道条件和功率等信息来决定是否采用将RRC连接建立请求信令和NAS业务请求信令合并发送的机制(简称信令合并发送机制)。 Example embodiments of the UE [0037] The present invention is employed to determine whether channel conditions and power information RRC connection establishment request signaling and NAS service request and sending the combined signaling mechanism (abbreviated combined signaling transmission mechanism).

[0038] 本发明实施例提出在LTE-A系统中,LTE-AUE在以初始接入为目的的随机接入过程之前,可以根据信道情况和/或UE的功率等级等信息判断当前信道质量是否满足预设的信道质量条件,如果是,则在随机接入过程中采用信令合并发送机制合并发送RRC连接建立请求信令和NAS业务请求信令;否则,在随机接入过程中仅发送RRC连接建立请求信令。 [0038] Example proposed in LTE-A system, LTE-AUE before the random access procedure at an initial access for the purpose, based on the current channel quality is based on channel conditions and / or the UE power class information such as the present invention, predetermined channel quality condition is satisfied, if yes, the combined use of the signaling mechanism transmits RRC connection request and sending the combined signaling and NAS service request signaling in a random access process; otherwise, transmits only random access procedure in the RRC connection establishment request signaling.

[0039] 下面结合附图对本发明实施例提供的技术方案进行说明。 [0039] The accompanying drawings will be described below in conjunction with the technical solutions provided in embodiments of the present invention.

[0040] 参见图4,本发明实施例提供的一种信令发送方法包括: [0040] Referring to FIG 4, the present invention is to implement a signaling method provided comprises:

[0041] SlOU UE在发起初始接入之前,当判定随机接入需要采用的信道的信道质量满足预设的信道质量条件时,将RRC连接建立请求信令与NAS业务请求信令进行合并。 [0041] SlOU UE before initiating the initial access, when a preset channel quality condition determining a random access channel to be utilized to meet the channel quality, the RRC connection establishment request signaling and NAS service request signaling merge. [0042] S102、UE向eNB发起随机接入过程,并通过eNB返回的随机接入响应中指示的资源发送信息3 (Msg3),其中包含将RRC连接建立请求信令与NAS业务请求信令进行合并后的信令(以下简称合并后的信令)。 [0042] S102, UE initiates a random access procedure to the eNB, and send a message 3 (Msg3) eNB through a random access response resource returned indicated, which comprises RRC connection establishment request signaling and NAS service request signaling signaling combined (hereinafter the combined signaling). [0043] 以初始接入为目的的随机接入是UE在空闲模式下发起的,此时采用的是竞争随机接入方式。 [0043] In an initial access for the purpose of random access is initiated by the UE in idle mode, this time using the competitive random access manner. [0044] 下面给出UE判断是否进行RRC连接建立请求信令与NAS业务请求信令合并发送的两种具体实施例。 [0044] The following presents UE determines whether the two kinds of RRC connection establishment request signaling and NAS service request signaling transmitted combined embodiments. [0045] 实施例一:[0046] 空闲模式下的UE在进行小区选择或小区重选过程中,需要使用一些测量量,例如UE的接收信号功率(RSRP)等,RSRP是通过对eNB发送的信号进行测量所得到的测量量。 [0045] Example a: [0046] UE in idle mode performing cell selection or cell reselection procedure, the need to use some measurements, such as a UE received signal power (RSRP) and the like, by sending to the eNB RSRP of the measuring the amount of signal obtained. [0047] UE可以根据小区选择或小区重选过程中的测量量来判断信道质量,例如,可以将RSRP与预设的RSRP门限值A进行比较,当RSRP大于A时,说明信道质量较好,即随机接入需要采用的信道的信道质量满足预设的信道质量条件,可以在随机接入过程中通过Msg3携带合并后的信令;否则,说明信道质量不足以支持Msg3携带合并后的信令,即随机接入需要采用的信道的信道质量不满足预设的信道质量条件,仅能在Msg3中携带RRC连接建立请求信令。 [0047] UE may be determined according to the channel quality measurement quantity cell selection or cell reselection procedure, for example, may be preset RSRP RSRP threshold A are compared, when the RSRP is larger than A, described better channel quality , i.e., the channel quality of the random access channel to be utilized to meet the predetermined channel quality condition, the combined signaling may be carried by the Msg3 random access procedure; otherwise, indicating the channel quality channel is insufficient to support the combined carrying Msg3 order, i.e., random access channel need not satisfy the predetermined channel quality a channel quality conditions, RRC connection establishment request carries only signaling in Msg3. [0048] 较佳地,所述预设的RSRP门限值A,是由eNB通过小区广播发送给UE的。 [0048] Preferably, the preset RSRP threshold A, the cell broadcast by the eNB is sent to the UE. [0049] 具体的发起初始接入的步骤包括:[0050] 步骤一:UE确定需要发起初始接入过程,则预先根据目前的测量结果RSRP判断当前的信道质量是否满足预设的信道质量条件,如果RSRP大于预设的RSRP门限值,则UE的RRC层将RRC连接建立请求信令和NAS业务请求信令合并成一个包发送至底层,即媒体接入控制(MAC)层;否则UE的RRC层仅发送RRC连接建立请求信令包至MAC层。 Step [0049] Specific initiates an initial access comprising: [0050] Step a: determining the UE needs to initiate an initial access procedure, the measurement result according to the current pre-determined RSRP predetermined channel quality condition is satisfied current channel quality, If the RSRP is larger than the predetermined RSRP threshold, the RRC layer of the UE transmits the RRC connection establishment request signaling and NAS service request signaling packet to be combined into a bottom layer, i.e., a media access control (MAC) layer; otherwise, the UE RRC layer sends RRC only signaling connection establishment request packet to the MAC layer. [0051] 步骤二:UE的MAC层接收RRC层发送的指示,开始发起随机接入过程,根据Msg3大小、group A、group B和路损信息等选择合适的Preamble组,在选定的组中随机选取Preamble,在合适的PRACH资源上发送Preamble给eNB。 [0051] Step Two: MAC layer of the UE RRC layer receives an indication of transmission, to initiate a random access procedure starts, according to the size of the Msg3, group A, group B and the path loss information Preamble Select the appropriate group, in the selected group Preamble randomly selected, Preamble to the eNB transmits on the appropriate PRACH resource. [0052] 另外,如果需要对版本IO(RlO)的UE进行优化,可以利用特殊的Preamble或者PRACH资源等向eNB指示。 [0052] Further, if necessary optimized version IO (RlO) of the UE, or may be utilized Preamble special PRACH resource indication to the eNB. 所述优化具体包括:对于RlOUE可以用区别于版本8 (R8)的UE的Preamble或者PRACH资源发起随机接入,eNB在接收到随机接入请求后可以准确地判断UE的版本,对于R10UE,eNB明确知道此时UE希望发起信令合并发送,则在分配Msg3消息资源时可以据此分配足够大的资源用以承载合并后的信令;对于R8UE,则维持原分配方案,避免浪费。 Said optimization comprises: Preamble for RlOUE or PRACH resource may be distinguished from the release 8 (R8) initiates a random access of the UE, the eNB can accurately determine the version of the UE after receiving the random access request, for R10UE, eNB at this time, we know exactly UE wishes to initiate a combined signaling transmission, whereby it is possible to allocate sufficient resources to carry signaling when combined resource allocation message Msg3; for R8 UE, maintaining the original allocation, to avoid wastage. [0053] 步骤三:eNB在信息2 (Msg2)窗口中向UE发送随机接入响应,其中包含上行链路授权(UL grant)信息。 [0053] Step Three: eNB transmits a random access information 2 (Msg2) window in response to the UE, which includes an uplink grant (UL grant) message. [0054] 如果步骤二中UE指示了eNB自身为R10UE,则eNB在分配资源时可以考虑为该UE分配更大的资源或者更高的MCS,用以承载携带有合并后的信令的Msg3。 [0054] If the UE indicates a step two eNB itself as R10UE, the eNB may be considered when allocating resources for the UE resource assignment larger or higher MCS, for carrying the carrying signaling Msg3 have merged. [0055] 步骤四:UE的MAC层接收到随机接入响应后,按照UL grant的指示在相应的资源上发送Msg3,其中含有合并后的信令或者RRC连接建立请求信令。 [0055] Step Four: MAC layer of the UE after receiving the random access response, in accordance with the UL grant indicates Msg3 transmission on a corresponding resource, which contains the combined signaling or the RRC connection establishment request signaling. [0056] 需要说明的是,即使UE的RRC层下发了合并后的信令给MAC层,MAC层也未必可以发送合并后的信令,因为如果随机接入响应中分配的资源不足以承载合并后的信令,则UE的MAC层无法传输合并后的信令给eNB,此时,MAC层可以跟UE的RRC层进行交互,请求UE的RRC层仅下发RRC连接建立请求信令给MAC层,那么MAC层仅传输RRC连接建立请求信令给eNB。 [0056] Incidentally, even if the signaling sent at a combined RRC layer of the UE to the MAC layer, MAC layer signaling may not be combined, as if in response to the random access resource allocated bearer is insufficient the combined signaling, the MAC layer of the UE can not transmit the combined signaling to the eNB, this time, the MAC layer can interact with the RRC layer of the UE, the RRC layer of the UE requests issued only RRC connection establishment request signaling to the MAC layer, the MAC layer transmits only RRC connection establishment request signaling to the eNB.

[0057] 步骤五:eNB接收到Msg3后,获取其中携带的内容,如果其中携带的仅有RRC连接建立请求信令,则对RRC连接建立请求信令进行处理;如果同时还包含了NAS业务请求信令,则也对NAS业务请求信令进行相应处理。 [0057] Step Five: eNB after receiving the Msg3, acquire the content carried in, only if carried in RRC connection establishment request signaling to the RRC connection request signaling process; if at the same time also contains the NAS service request signaling the NAS service request signaling to be dealt with accordingly.

[0059] UE的RRC层在发起初始接入之前,先与底层(MAC层或物理层)进行交互,指示底层上报必要的信道信息,例如:路损、RSRP, UE的功率等级等等,UE的RRC层对底层上报的信息进行综合判断,例如,根据需要发送的数据大小、路损、功率爬坡信息、期望接收功率等估算所需的发射功率,如果发射功率高于UE的最大发射功率,则判定随机接入需要采用的信道的信道质量不满足预设的信道质量条件,不能采用合并发送的机制,RRC连接建立请求信令和NAS业务请求信令只能分别发送,否则判定随机接入需要采用的信道的信道质量满足预设的信道质量条件,可以发送合并后的信令。 [0059] RRC layer of the UE before initiating an initial access, with the first bottom (MAC layer or physical layer) interactions, indicating underlying channel reports necessary information, for example: path loss, RSRP of, power levels, etc. UE, UE RRC layer underlying the information reported by the comprehensive judgment, for example, the size of the data to be transmitted, the path loss, power ramp information needed to estimate the transmission power desired received power and the like, the maximum transmit power if the transmit power of the UE is higher than , it is determined that the random access channel needs to use the channel quality does not satisfy a predetermined channel quality conditions, can not be transmitted using the combined mechanism, the RRC and NAS signaling connection establishment request signaling service request can only be sent separately, or random access determination the need to use the channel quality meets the preset channel channel quality conditions, signaling may be sent combined.

[0060] 具体的发起初始接入的过程包括: [0060] Specific initiation initial access process comprises:

[0061 ] 步骤一:UE确定需要发起初始接入过程,UE的RRC层通知底层上报信道信息,并根据底层上报的信道信息,判断随机接入需要采用的信道的信道质量是否满足预设的信道质量条件,如果是,则UE的RRC层将RRC连接建立请求信令和NAS业务请求信令合并成一个包发送至MAC层;否则,UE的RRC层仅发送RRC连接建立请求信令包至MAC层。 [0061] Step a: UE determines that initiates an initial access procedure, the RRC layer of the UE notifies the underlying reporting channel information according to the channel information of the underlying report and determines whether the channel quality of the random access need channel meets the preset channel quality conditions, and if so, the RRC layer of the UE transmits the RRC connection establishment request signaling and NAS service request signaling packet to be combined into a MAC layer; otherwise, only the RRC layer of the UE transmits RRC connection establishment request signaling packet to the MAC Floor.

[0062] 步骤二:UE的MAC层接收RRC层发送的指示,开始发起随机接入过程,根据Msg3大小、group A、group B和路损信息等选择合适的Preamble组,在选定的组中随机选取Preamble,在合适的PRACH资源上发送Preamble给eNB。 [0062] Step Two: MAC layer of the UE RRC layer receives an indication of transmission, to initiate a random access procedure starts, according to the size of the Msg3, group A, group B and the path loss information Preamble Select the appropriate group, in the selected group Preamble randomly selected, Preamble to the eNB transmits on the appropriate PRACH resource.

[0063] 另外,如果需要对版本IO(RlO)的UE进行优化,可以利用特殊的Preamble或者PRACH资源等向eNB指示。 [0063] Further, if necessary optimized version IO (RlO) of the UE, or may be utilized Preamble special PRACH resource indication to the eNB.

[0064] 步骤三:eNB在Msg2窗口中向UE发送随机接入响应,其中包含上行链路授权(ULgrant)信息。 [0064] Step Three: eNB sends Msg2 window random access response to the UE, wherein the uplink grant comprising (ULGrant) information.

[0065] 如果步骤二中UE指示了eNB自身为R10UE,则eNB在分配资源时可以考虑为该UE分配更大的资源或者更高的MCS,用以承载携带有合并后的信令的Msg3。 [0065] If the UE indicates a step two eNB itself as R10UE, the eNB may be considered when allocating resources for the UE resource assignment larger or higher MCS, for carrying the carrying signaling Msg3 have merged.

[0066] 步骤四:UE的MAC层接收到随机接入响应后,按照UL grant的指示在相应的资源上发送Msg3,其中含有合并后的信令或者RRC连接建立请求信令。 [0066] Step Four: MAC layer of the UE after receiving the random access response, in accordance with the UL grant indicates Msg3 transmission on a corresponding resource, which contains the combined signaling or the RRC connection establishment request signaling.

[0067] 如果UE的RRC层下发了合并后的信令给MAC层,MAC层也未必可以发送合并后的信令,因为如果随机接入响应中分配的资源不足以承载合并后的信令,则UE的MAC层无法传输合并后的信令给eNB,此时,MAC层可以跟UE的RRC层进行交互,请求UE的RRC层仅下发RRC连接建立请求信令给MAC层,那么MAC层仅传输RRC连接建立请求信令给eNB。 [0067] If the signaling is sent at a combined RRC layer of the UE to the MAC layer, MAC layer signaling may not be combined, since the signaling if the combined response to random access resource allocated bearer is insufficient after signaling, the MAC layer of the UE to the eNB can not transmit the combined, at this time, the MAC layer can interact with the RRC layer of the UE, the RRC layer requests the UE RRC only signaling connection establishment request issued to the MAC layer, the MAC only the transport layer RRC connection establishment request signaling to the eNB.

[0068] 步骤五:eNB接收到Msg3后,获取其中携带的内容,如果其中携带的仅有RRC连接建立请求信令,则对RRC连接建立请求信令进行处理;如果同时还包含了NAS业务请求信令,则也对NAS业务请求信令进行相应处理。 [0068] Step Five: eNB after receiving the Msg3, acquire the content carried in, only if carried in RRC connection establishment request signaling to the RRC connection request signaling process; if at the same time also contains the NAS service request signaling the NAS service request signaling to be dealt with accordingly.

[0069] 另外,UE的MAC层也可以根据路损、RSRP、UE的功率等级等,判断随机接入需要采用的信道的信道质量满足预设的信道质量条件,并将判断结果上报给RRC层,如果信道质量满足预设的信道质量条件,则RRC层将RRC连接建立请求信令和NAS业务请求信令合并成一个包发送至MAC层;否则UE的RRC层仅发送RRC连接建立请求信令包至MAC层。 [0069] Further, the MAC layer of the UE may be in accordance with the path loss, RSRP of, UE power levels, etc., it determines the channel quality of a channel random access need preset channel quality condition is satisfied, and the determination result is reported to the RRC layer , if the preset channel quality a channel quality conditions are satisfied, the RRC layer transmits the RRC connection establishment request signaling and NAS service request signaling combined into a packet to the MAC layer; otherwise, only the RRC layer of the UE transmits RRC connection establishment request signaling packet to the MAC layer. [0070] 其中,MAC层判断随机接入需要采用的信道的信道质量满足预设的信道质量条件的判断准则,可以是路损是否小于路损门限值,如果是,则判定信道质量满足预设的信道质量条件;否则,判定信道质量不满足预设的信道质量条件。 [0070] wherein, the channel quality the MAC layer determines a random access need channel satisfies a criterion predetermined channel quality conditions may be the path loss is less than the path loss threshold, if so, determines the channel quality satisfies a pre- channel quality conditions set; otherwise, it is determined channel quality does not satisfy a predetermined channel quality conditions.
