[0013] 无线通信系统中,现有技术随机接入过程如图1所示,具体步骤如下: [0013] a wireless communication system, the prior art random access procedure is shown in Figure 1, the following steps:

[0014] 1)终端在随机接入信道上发送"无线资源控制连接建立请求"信令给接入网,请求 [0014] 1) the terminal transmits "RRC connection request" to the access signaling in a random access channel, request

接入; Access;

[0015] 2)接入网在前向接入信道上发送"无线资源控制连接建立"信令给终端,确认允许终端接入,以及终端以何种方式接入; [0015] 2) to the access network forward access channel transmits "RRC connection setup" signaling to the terminal, the terminal is allowed access confirmation, and the manner in which the access terminal;

[0016] 3)终端依照接入网的指示,接入无线网络,最后以"无线资源控制连接建立完成" 信令回复接入网。 [0016] 3) indicative of the terminal in accordance with the access network, wireless access network, and finally a "RRC Connection Setup Complete" reply signaling access network.

[0017] 在此过程中,R99(99版本)阶段,在随机接入信道上需要解决随机碰撞问题,在随 [0017] In this process, R99 (99 version) stage, a random access channel to be solved the problem of random collisions, with the

机接入信道上不能够传送较大数据,以及此R99阶段的终端在初始接入时无须向网络提供 Machine is not able to transmit a larger access channel data, and a terminal stage of this R99 required to provide initial access to the network

详细的该终端无线接入能力信息。 Detail of the radio access capability information of the terminal. 所以,终端在初始申请接入时,"无线资源控制连接建立 Therefore, access to the terminal in the initial application, "RRC Connection Setup

请求"信令中未携带任何该终端无线接入能力信息,而是在接入完成后终端通过"无线资源 Request "does not carry any signaling radio access capability information of the terminal, but after completion of the access terminal through a" radio resource

过"无线资源控制连接建立完成"信令,将全部的该终端无线接入能力信息详细提供给接入 The "RRC connection setup complete" signaling, all the terminal capability information of the wireless access is provided to access detailed

网使用。 Net use.

[0019] 可以看出,终端无线接入能力信息传递的设计方式变得复杂低效,会重复传送同样的能力参数或者类别。 [0019] As can be seen, the radio access capability information delivery terminal design approach becomes inefficient complex, the ability to be repeatedly transmitted parameters or the same category. 特别是在初始申请接入时需要将必要的终端无线接入能力信息参数或者类别挑选出来放入"无线资源控制连接建立请求"信令中,错漏的情况经常发生,导致协议描述常常更改,不能稳定。 A terminal needs the necessary radio access capabilities information category selection parameters or especially at the initial access request out into the "RRC connection request" signaling, where mistakes often occur, resulting in changes to the protocol described often not stable.

[0020] 经过演进,随机接入过程采用如图2所示过程来实现,具体步骤如下: [0021] 1)终端在物理随机接入信道上发送接入前导给接入网; [0020] After evolution of a random access procedure using the procedure shown in Figure 2 to achieve the specific steps are as follows: [0021] 1) the terminal sends an access channel, a physical random access preamble to the access network;

[0022] 2)接入网以用于上行发射定时的时间调整信息以及用于发送调度请求的资源信息响应终端; [0022] 2) to the access network for uplink transmission timing adjustment information and a time for transmitting scheduling request resource information in response to the terminal;

[0023] 3)终端依照接入网的指示,进行时间调整,然后在接入网指派的使用共享数据信道或使用物理随机接入信道的时频域资源上,发送调度请求,为后续的上行数据和控制信令向接入网发送信息申请合适的资源; [0023] 3) indicative of the terminal in accordance with the access network, the time adjustment, and then the frequency domain resource assigned to the access network when using shared data channel or a physical random access channel, transmitting the scheduling request, an uplink for subsequent sending signaling data and control information to the access network to apply the appropriate resources;

[0024] 4)接入网依照终端的调度请求,调整资源分配,为终端分配合理的资源,并通过指派共享数据信道上用于传送数据或者控制信令的资源信息回复终端; [0024] 4) the access network in accordance with the scheduling request from the terminal, to reallocate resources, a reasonable allocation of resources to the terminal, and for transmitting the data by assigning a shared data channel or the control signaling resource information response terminal;

[0025] 5)终端依照接入网的指示,使用指派的共享数据信道资源进行数据或控制信令发送。 [0025] 5) indicative of the terminal in accordance with the access network, the shared data channel using the assigned resource control signaling or data transmission.

[0026] 以上5步是长期演进的一种优化方向的流程实现,但这种实现是原则性上的,并未对终端无线接入能力信息的传递做出规定。 [0026] Step 5 above is an optimization process direction to achieve long-term evolution, but this implementation is that the terminal does not make provision for transmitting radio access capability information on principle.

具体实施方式 Detailed ways

[0041] 本发明的随机接入过程中终端无线接入能力信息传送的方法是通过终端在非同步随机接入情况下向接入网发送的第一个层3控制信令消息,将全部终端无线接入能力信息传递给接入网的方式,完成终端无线接入能力信息传递。 [0041] The random access procedure according to the present invention in a terminal of a radio access capability information is transmitted through the first layer of the terminal to the access network in case of non-synchronized random access 3 control signaling message, all terminals radio access capability information to the network access mode, the radio access capability information of the terminal to complete the transfer. [0042] 下面结合附图对本发明所述方法作进一步的描述: [0042] DRAWINGS further description of the method of the present invention:

[0043] 本实施例提出了一种随机接入过程中终端无线接入能力信息传送的设计方法,如图3所示。 [0043] The present embodiment proposes a method of transferring a design of a random access procedure in a radio access capability information of the terminal, as shown in FIG.

5[0044] 步骤IIO,终端在物理随机接入信道上发送接入前导给接入网,请求接入; 5 [0044] Step the IIO, the access terminal transmits to the access preamble, an access request for a physical random access channel;

[0045] 步骤120,接入网以用于上行发射定时的时间调整信息以及用于发送调度请求的 [0045] Step 120, the access network for uplink transmission timing adjustment information and a time for transmitting the scheduling request

资源信息响应终端,以确认允许终端接入; Resource information in response to the terminal, the terminal is allowed access to acknowledge;

[0046] 这里只是确认允许终端接入,由于在步骤110中终端只有物理层信息传递到接入 [0046] where the terminal is allowed access only to confirm, since the terminal in step 110 passes the information to the access physical layer only

网,所以接入网无法有足够的信息确定终端以何种方式接入,接入网只是笼统的发送"用于 Network, so that the access network can not have sufficient information to determine the manner in which the access terminal, the access network transmits the only general "for

发送调度请求的资源信息"给终端,也就是发送一个授权给终端。 Transmitting scheduling request resource information "to the terminal, an authorization is sent to the terminal.

[0047] 步骤130,终端依照接入网的指示,进行时间调整,以使接入网和终端同步; [0047] Step 130, the terminal in accordance with the indication of the access network, time adjustment, so that the terminal and access network synchronization;

[0048] 步骤140,终端在接入网指派的使用共享数据信道或者使用物理随机接入信道的 [0048] Step 140, the terminal using the shared data channel assigned to the access network, or using a physical random access channel

时频域资源上发送调度请求,为后续的上行数据和控制信令向接入网发送信息申请合适的 A time-frequency domain resources send a scheduling request, transmits request information for subsequent uplink data and control signaling to the access network suitable

资源; Resources;

[0049] 该步是层2的处理,所述向接入网申请合适的资源包括两个部分: [0049] This step is a process of the layer 2, the application of the appropriate resources to the access network comprises two parts:

[0050] 1.初始发送上行数据所需要的资源,也就是发送调度请求后,后续接着发送第一 [0050] 1. Initial uplink data transmission resources required, i.e. after sending scheduling request, and then transmits the subsequent first

包上行数据所需要的资源; An uplink packet data resources needed;

[0051] 2.初始发送上行控制信令所需要的资源,也就是发送调度请求后,后续接着发送第一包控制信令所需要的资源。 After [0051] 2. Send the initial uplink control signaling required for resource scheduling request is sent, followed by a subsequent transmission of the first packet resource control signaling required.

[0052] 此时,终端还不知道具体分配给自己发送初始数据和信令的资源是多少,标号为多少,只是把自己的调度要求提交给接入网。 [0052] In this case, the terminal does not know the specific initial transmission resources allocated to itself is the number of data and signaling, designated number, just submit their request to the access network scheduling.

[0053] 步骤150,接入网依照终端的调度请求来调整资源分配,为终端分配合理的初始接入资源,并将指派的共享数据信道上用于传送数据或者控制信令的资源信息回复终端; [0054] 步骤160,终端依照接入网指派的共享数据信道上行资源进行上行数据或者控制信令发送,在终端发送给接入网的第一条层3控制信令中携带完整的终端无线接入能力信息,将所述终端无线接入能力的信息传递给接入网; [0053] Step 150, the access network adjusts the resource allocation request from the terminal in accordance with scheduling, resource allocation reasonable initial access for the terminal, and assigning a shared data channel for transmitting data or control signaling resource information response terminal ; [0054] step 160, the terminal performs the uplink data in accordance with the shared data channel uplink resource assignment or the access network control signaling, the first layer is transmitted to the access terminal 3 carries control signaling complete wireless terminal access capability information, transmitting information to the terminal to the radio access capabilities of the access network;

[0055] 从该步开始,终端才开始发送层3的数据和信令。 [0055] From this step, the terminal began sending data and signaling layer 3. 可以看出,在演进的这一种接入方式中,将层1层2层3的处理串行化了,用以减少随机接入冲突和实现快速同步接入。 As can be seen, in this evolved access mode, the treatment layer 1 layer 2 layer 3 serialized, random access collisions and to reduce fast synchronous access. [0056] 终端无线接入能力信息包括层1到高层的接入能力信息,但它仅限于层3进行使用,也就是层3的处理实体需要这些信息。 [0056] The terminal capability information comprises radio access capability information of the access layer to the upper layer 1, but it is limited to the use of layer 3, i.e. the layer 3 processing entity need this information. 层1到高层的无线使用控制,都是由层3的处理实体依据具体信息控制处理的,如层3通过无线接入能力信息配置合适的层1层2控制参数。 1 to an upper layer using the radio control, layer 3 is the processing entity of control processing based on the specific information, such as a layer 3 is disposed suitable control parameters Layer 1 Layer 2 by the radio access capability information.

[0057] 在所述第一条层3控制信令中携带全部完整的终端无线接入能力信息,可以达到最快速传送的目的。 [0057] Full carry all terminal capability information of the radio access first layer 3 control signaling, can achieve the fastest transmission.

[0058] 步骤170,接入网接收该第一条层3控制信令后,保存信令中携带的全部完整的终端无线接入能力信息,决定是否在层3允许该终端接入和以何种方式接入。 After [0058] Step 170, the access network receives the first layer 3 control signaling, complete preservation of all terminal radio access capabilities information carried in signaling, deciding whether to allow the access terminal to the layer 3 and Ho access ways. [0059] 例如移动切换,接入网要根据UE能力决定切换的候选目标小区。 [0059] such as a mobile switch, the access network determines to handover candidate target cells according to the UE capabilities. UE能力信息一直要全部保留在接入网侧,直到这个UE关机或者移动出该接入网范围。 UE capability information has been retained for all of the access network side, the UE until the shut down or moved out of range of the access network. 也就是UE实例存在则UE能力信息一直存在。 Is UE examples exist UE capability information has always existed.

[0060] 在其他实施例中,所述步骤160中,在终端发送给接入网的除第一条层3控制信令外的任意一条层3控制信令中携带全部完整的无线接入能力信息。 [0060] In other embodiments, the step 160, a layer 3 control signaling is sent to any access network in addition to the first layer 3 control signaling is carried in a terminal complete all radio access capabilities information.

[0061] 在另一实施例中,所述步骤160中,终端无线接入能力信息的发送可以根据业务需要分次传送。 [0061] In another embodiment, the step 160, the terminal transmits the radio access capability information can be transmitted divided according to business needs. 如切换过程信令中发送切换相关的,业务建立过程中发送业务相关的。 The transmitting handover-related, business establishment process traffic transmitted in the handover procedure related signaling.
