Description

一种增强型专用信道传输上行数据的方法及*** Method and system for transmitting uplink data by enhanced dedicated channel

技术领域 Technical field

本发明涉及增强型专用信道传输承载模式技术，尤其涉及到一种增强型专用信道传输上行数据的方法及***。 The present invention relates to an enhanced dedicated channel transmission bearer mode technique, and more particularly to an enhanced dedicated channel for transmitting uplink data.

背景技术 Background technique

在无线通讯***中， IUB ( Interconnection of type B, B类互联）接口是无线网络控制器和节点 B之间的逻辑接口。 IUR ( Interconnection of RNC , 无线网络控制器之间互联接口）接口是无线网络控制器用于同其他无线网络控制器进行信令和数据交互的接口，是无线网络子***之间互联的纽带。 In a wireless communication system, an IUB (Interconnection of Type B) interface is a logical interface between a radio network controller and a Node B. The IUR (Interconnection of RNC) interface is the interface used by the radio network controller for signaling and data interaction with other wireless network controllers. It is the link between the wireless network subsystems.

当一个终端建立了无线接入网的连接，并在 IUR接口产生了软切换，就会用到多个无线网络控制器的资源，此时，不同的无线网络控制器充当着不同的角色：其中，用于保持该终端与核心网的接口连接的无线网络控制器称为服务无线网络控制器。服务无线网络控制器负责核心网和终端之间的数据传送和与核心网的接口信令的转送和接收，负责进行无线资源控制，负责对空中接口的数据进行层二的处理，并执行基本无线资源管理操作，如切换判决、外环功率控制和无线接入承载的参数向空口传输信道参数的转化等。 When a terminal establishes a connection to the radio access network and soft handover occurs on the IUR interface, resources of multiple radio network controllers are used. At this time, different radio network controllers play different roles: The radio network controller for maintaining the interface connection between the terminal and the core network is called a service radio network controller. The service radio network controller is responsible for data transmission between the core network and the terminal and transmission and reception of interface signaling with the core network, is responsible for radio resource control, is responsible for layer 2 processing of the air interface data, and performs basic wireless operation. Resource management operations, such as handover decisions, outer loop power control, and conversion of radio access bearer parameters to air interface transmission channel parameters.

而服务无线网络控制器以外的其他无线网络控制器称为漂移无线网络控制器。漂移无线网络控制器控制该终端使用的小区，如果需要，漂移无线网络控制器还可以进行宏分集合并。当该终端使用公共传输信道时，漂移无线网络控制器不会进行用户面数据的层二处理，只是将空口数据透明的通过 IUR接口的路由传递给服务无线网络控制器。一个终端的漂移无线网络控制器可以不止一个。 Other wireless network controllers other than the serving radio network controller are called drift wireless network controllers. The drift radio network controller controls the cell used by the terminal, and if necessary, the drift radio network controller can also perform macro diversity combining. When the terminal uses the common transport channel, the drift radio network controller does not perform layer 2 processing of the user plane data, but only passes the route of the air interface data transparently through the IUR interface to the serving radio network controller. There can be more than one drift wireless network controller for one terminal.

高速上行分组接入技术的目标是在上行方向改善容量和数据吞吐量，降低专用信道中的迟滞。由高速上行分组接入技术引入了一条新的传输信道：增强型专用信道，对物理层和媒体接入控制层的实现进行改进，可以达到最大理论上行数据速率为 5.6 兆比特每秒。高速上行分组接入技术保留了软切换的特性。空中接口接收的媒体接入控制协议数据单元，解复用为媒体接入控制流，以增强型专用信道上行数据帧的形式从节点 B经由 IUB接口或者漂移无线网络控制器经由 IUR接口，通过媒体接入控制流对应的传输承载 (每一个媒体接入控制流有一个对应的 _IUB接口和 /或 _IUR接口传输承载），传输到服务无线网络控制器。 The goal of high-speed uplink packet access technology is to improve capacity and data throughput in the upstream direction and reduce hysteresis in dedicated channels. A new transport channel is introduced by the high-speed uplink packet access technology: The enhanced dedicated channel improves the implementation of the physical layer and the medium access control layer to achieve a maximum theoretical uplink data rate of 5.6 megabits per second. High-speed uplink packet access technology retains soft cut Change the characteristics. The media access control protocol data unit received by the air interface is demultiplexed into a media access control flow, and is transmitted from the node B via the IUB interface or the drift radio network controller via the IUR interface in the form of an enhanced dedicated channel uplink data frame. The transmission bearers corresponding to the access control flow (each medium access control flow has a corresponding _IUB interface and/or _IUR interface transmission bearer) and are transmitted to the serving radio network controller.

随着技术发展，双载波高速上行分组接入技术（）希望被引入现有***，此技术可以使终端能够在两个载波上以高速上行分组接入技术发送数据，从而使得上行链路数据速率得以倍增。双载波中包含高速专用物理控制信道的载波称为主载波，双载波中余下的另外一个载波称为辅载波。对于一个终端而言，双载波中的各载波均有自己独立的增强型专用信道激活集。双载波高速上行分组接入技术的引入，需要考虑后续多载波（如三载波，四载波）的易扩展性。多载波中包含高速专用物理控制信道的载波称为主载波，其他载波分别称为第二载波，第三载波，以及四载波中的第四载波。 With the development of technology, dual-carrier high-speed uplink packet access technology () is expected to be introduced into existing systems, which enables the terminal to transmit data on two carriers with high-speed uplink packet access technology, thereby making the uplink data rate Can be multiplied. The carrier including the high-speed dedicated physical control channel in the dual carrier is called the primary carrier, and the other carrier in the dual carrier is called the secondary carrier. For a terminal, each carrier in the dual carrier has its own independent enhanced dedicated channel activation set. The introduction of dual-carrier high-speed uplink packet access technology requires consideration of the scalability of subsequent multi-carriers (such as three-carrier and four-carrier). A carrier including a high-speed dedicated physical control channel in a multi-carrier is referred to as a primary carrier, and other carriers are referred to as a second carrier, a third carrier, and a fourth carrier among the four carriers, respectively.

一个典型的双载波高速上行分组接入技术的场景如图 1所示：终端使用双载波高速上行分组接入技术技术，同时在主载波和辅载波上发送数据。主载波有自己独立的增强型专用信道激活集，包含节点 B1 下的小区 1和节点 B2 下的小区 3。辅载波有自己独立的增强型专用信道激活集，包含节点 B1 下的小区 2和节点 B3下的小区 4。 A typical dual-carrier high-speed uplink packet access technology scenario is shown in Figure 1: The terminal uses dual-carrier high-speed uplink packet access technology to transmit data on both the primary and secondary carriers. The primary carrier has its own independent enhanced dedicated channel activation set, including cell 1 under node B1 and cell 3 under node B2. The secondary carrier has its own independent enhanced dedicated channel activation set, including cell 2 under node B1 and cell 4 under node B3.

终端通过主载波发送上行数据到网络侧，该上行数据在网络侧的传输路径为： The terminal sends uplink data to the network side through the primary carrier, and the transmission path of the uplink data on the network side is:

(管辖小区 1的节点）节点 B1至无线网络控制器 1 (即服务无线网络控制器） (node of jurisdiction 1) Node B1 to radio network controller 1 (ie serving radio network controller)

(管辖小区 3的节点）节点 B2-至无线网络控制器 1 (即服务无线网络控制器） (node of jurisdiction cell 3) Node B2- to radio network controller 1 (ie service radio network controller)

终端通过辅载波发送上行数据到网络侧，该上行数据在网络侧的传输路径为： The terminal sends the uplink data to the network side through the secondary carrier, and the transmission path of the uplink data on the network side is:

(管辖小区 2的节点）节点 B1至无线网络控制器 1 (即服务无线网络控制器） 1、（管辖小区 4 )节点 B3至无线网络控制器 2 (即漂移无线网络控制器）至无线网络控制器 1 (即服务无线网络控制器）。 (node of jurisdiction cell 2) node B1 to radio network controller 1 (ie serving radio network controller) 1. (Jurisdiction 4) Node B3 to Radio Network Controller 2 (ie, Drift Radio Network Controller) to Radio Network Controller 1 (ie, Serving Radio Network Controller).

现有双载波高速上行分组接入技术中，定义增强型专用信道传输承载模式包括 "共享模式" 和 "分离模式" 。其中： "共享模式" 是指所有上行载波上接收的同一个 MAC ( Media Access Control, 媒体接入控制）流均放在同一个传输承载上发送； "分离模式" 是指从不同的上行载波上接收的 MAC 流分别放在不同的传输承载上发送。定义增强型专用信道上行数据帧中的 "上行复用信息"为：当增强型专用信道的传输承载模式是 "共享模式"时， "上行复用信息" 设置为相应的编码，以表示承载此数据帧的载波，如主载波或者辅载波；当增强型专用信道的传输承载模式是 "分离模式" 时， "上行复用信息" 设置为空，或者 "上行复用信息" 被接收方忽略。 In the existing dual-carrier high-speed uplink packet access technology, the enhanced dedicated channel transmission bearer mode is defined to include "shared mode" and "separate mode". The "shared mode" means that the same MAC (Media Access Control) stream received on all uplink carriers is sent on the same transport bearer; "separate mode" refers to different uplink carriers. The received MAC flows are sent on different transport bearers. Defining the "uplink multiplexing information" in the uplink channel of the enhanced dedicated channel is: When the transmission bearer mode of the enhanced dedicated channel is "shared mode", the "uplink multiplexing information" is set to the corresponding code to indicate that the bearer is carried. The carrier of the data frame, such as the primary carrier or the secondary carrier; when the transmission bearer mode of the enhanced dedicated channel is "separate mode", the "uplink multiplexing information" is set to null, or the "uplink multiplexing information" is ignored by the receiver.

"共享模式" 下，在选定的传输承载上，传输携带有上行复用信息的增强型专用信道上行数据帧的具体方式如图 2所示。节点 B1接收了主辅两个载波上的同一个 MAC流 -1，放在同一个传输承载 -1上发送给无线网络控制器 1。在图示的 2个增强型专用信道上行数据帧中， "上行复用信息" 分别填写为主载波对应的编码或者辅载波对应的编码，来表示承载此数据帧的载波为主载波或者辅载波。同样，对于无线网络控制器 2 (漂移无线网络控制器），接收到来自节点 B3的增强型专用信道上行数据帧，将其转发至无线网络控制器 1 (服务无线网络控制器），增强型专用信道上行数据帧在传输承载 -2和 -3 上传递，增强型专用信道上行数据帧中 "上行复用信息" 设置为主载波对应的编码，来表示承载此数据帧的载波为主载波。 In the "shared mode", the specific manner of transmitting the enhanced dedicated channel uplink data frame carrying the uplink multiplexing information on the selected transmission bearer is as shown in FIG. 2. Node B1 receives the same MAC stream -1 on both the primary and secondary carriers, and sends it to the radio network controller 1 on the same transmission bearer -1. In the two enhanced dedicated channel uplink data frames shown in the figure, the "uplink multiplexing information" is respectively filled with the code corresponding to the primary carrier or the code corresponding to the secondary carrier, to indicate that the carrier carrying the data frame is the primary carrier or the secondary carrier. . Similarly, for the radio network controller 2 (drift radio network controller), the enhanced dedicated channel uplink data frame from the node B3 is received and forwarded to the radio network controller 1 (serving radio network controller), enhanced dedicated The channel uplink data frame is transmitted on the transmission bearers -2 and -3. The "uplink multiplexing information" in the enhanced dedicated channel uplink data frame is set to the code corresponding to the primary carrier, to indicate that the carrier carrying the data frame is the primary carrier.

"分离模式" 下，在选定的传输承载上，传输携带有上行复用信息的增强型专用信道上行数据帧的具体方式如图 3所示。节点 B1和无线网络控制器 1 (服务无线网络控制器）相连的 IUB接口，有 2个分开的传输承载，传输承载 -1专门用来承载主载波上接收的数据，传输承载 -4专门用来承载辅载波上接收的数据。节点 B1在传输承载 -1 上发送来源于主载波接收数据的增强型专用信道上行数据帧，在传输承载 -4上发送来源于辅载波接收数据的增强型专用信道上行数据帧。由于通过传输承载已经可以区别主辅载波接收数据,所以增强型专用信道上行数据帧中 "上行复用信息" 为空，或者 "上行复用信息" 被接收方忽略。同样，对于无线网络控制器 2 (漂移无线网络控制器），接收到来自节点 B3的增强型专用信道上行数据帧，将其转发至无线网络控制器 1 (服务无线网络控制器），来源于主载波接收数据的增强型专用信道上行数据帧在专门用于承载主载波上接收数据的传输承载 -2和 -3上传递，增强型专用信道上行数据帧中 "上行复用信息"设置为空，或者 "上行复用信息" 被接^：方忽略。 In the "separation mode", the specific manner of transmitting the enhanced dedicated channel uplink data frame carrying the uplink multiplexing information on the selected transmission bearer is as shown in FIG. The IUB interface connected to the Node B1 and the Radio Network Controller 1 (Serving Radio Network Controller) has two separate transmission bearers. The Transport Bearer-1 is dedicated to carry the data received on the primary carrier. The Transport Bearer-4 is dedicated to The data received on the secondary carrier is carried. The Node B1 transmits an enhanced dedicated channel uplink data frame derived from the primary carrier received data on the transport bearer-1, and transmits an enhanced dedicated channel uplink data frame derived from the secondary carrier received data on the transport bearer-4. Since the primary and secondary carrier receiving data can be distinguished by the transmission bearer, the "uplink multiplexing information" in the enhanced dedicated channel uplink data frame is empty, or "uplink multiplexing signal" The information is ignored by the receiver. Similarly, for the radio network controller 2 (drift radio network controller), the enhanced dedicated channel uplink data frame from the node B3 is received and forwarded to the radio network controller 1 (serving the wireless network) Controller), the enhanced dedicated channel uplink data frame derived from the primary carrier receiving data is transmitted on the transmission bearers-2 and -3 dedicated to receiving the received data on the primary carrier, and the enhanced dedicated channel uplink data frame is "upward complex" Use the message "Set to empty, or "Uplink multiplexing information" to be ignored by the ^: party.

对于无线网络控制器 1 (服务无线网络控制器）而言，其会聚了通过所有的传输途径上来的上行数据。然后通过上述信息，通过 "共享模式" 下的增强型专用信道上行数据帧中上行复用信息，或者通过 "分离模式" 下的分开的传输承载，以分开来源于主载波接收数据还是来源于辅载波接收数据，基于单独载波分别进行重排序以及宏分集合并。一旦来源于不同载波接收数据混淆在一起，则无法正常进行重排序以及宏分集合并，所有数据错误，导致实际业务不可用，最终掉网。 For Wireless Network Controller 1 (Serving Radio Network Controller), it aggregates upstream data over all transmission paths. Then, through the above information, the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel in the "shared mode" or the separate transmission bearer in the "separate mode" is used to separate the data received from the primary carrier or the secondary source. The carrier receives data, and performs reordering and macro diversity combining based on individual carriers. Once the data received from different carriers is confused, the reordering and macro diversity cannot be performed normally, and all data errors are caused, resulting in the actual service being unavailable and eventually falling out of the network.

目前，既有主载波增强型专用信道小区，又有辅载波增强型专用信道小区的节点 B或者漂移无线网络控制器，才会被服务无线网络控制器设定增强型专用信道传输承载模式信息。如图 1 中的无线网络控制器 1 (服务无线网络控制器）经由 IUB接口或者 IUR接口配置给节点 B1 , 节点 B2, 无线网络控制器 2 (漂移无线网络控制器）。随后，这些节点 B 或者无线网络控制器要求依照增强型专用信道传输承载模式信息选择传输承载，以及设置增强型专用信道上行数据帧中的 "上行复用信息" ，进行增强型专用信道上行数据帧的传输。 At present, the enhanced dedicated dedicated channel transmission bearer mode information is set by the serving radio network controller, both the primary carrier enhanced dedicated channel cell and the secondary carrier enhanced dedicated channel small node B or the drift wireless network controller. The radio network controller 1 (serving radio network controller) in Fig. 1 is configured to the node B1, the node B2, and the radio network controller 2 (drift radio network controller) via the IUB interface or the IUR interface. Subsequently, the Node B or the radio network controller requests to select a transmission bearer according to the enhanced dedicated channel transmission bearer mode information, and set "uplink multiplexing information" in the enhanced dedicated channel uplink data frame to perform an enhanced dedicated channel uplink data frame. Transmission.

而其他情况，只有单一载波的增强型专用信道小区的节点 B或者漂移无线网络控制器，包括只有主载波增强型专用信道小区的节点 B或漂移无线网络控制器（如图 1中的节点 B2 ) , 以及只有辅载波增强型专用信道小区的节点 B或漂移无线网络控制器（如图 1中的节点 B3 , 无线网络控制器 2 ) ，是不会被服务无线网络控制器设定增强型专用信道传输承载模式信息。随后 , 这些节点 B或漂移无线网络控制器以单载波的方式进行增强型专用信道上行数据帧的传输。也就是选择同一个 MAC 流放在同一个传输承载上发送，设置增强型专用信道上行数据帧中的上行复用信息为空，或者增强型专用信道上行数据帧中的上行复用信息被接收方忽略，将增强型专用信道上行数据帧传输到接收方。 In other cases, only the Node B or the drift radio network controller of the enhanced dedicated channel cell of a single carrier, including the Node B of the primary carrier enhanced dedicated channel cell or the drift radio network controller (such as Node B2 in FIG. 1) And the Node B or the drift radio network controller (such as Node B3 and Radio Network Controller 2 in FIG. 1) that only has the secondary carrier enhanced dedicated channel cell, is not set by the serving radio network controller to set the enhanced dedicated channel. Transfer bearer mode information. Subsequently, the Node B or the drift radio network controller transmits the enhanced dedicated channel uplink data frame in a single carrier manner. That is, the same MAC stream is selected to be sent on the same transport bearer, and the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel is set to be empty, or the enhanced dedicated channel is used. The uplink multiplexing information in the uplink data frame is ignored by the receiver, and the enhanced dedicated channel uplink data frame is transmitted to the receiver.

但是，在增强型专用信道上行数据帧中的 "上行复用信息" 中，主载波对应的编码值为 0 , 而增强型专用信道上行数据帧中 "上行复用信息" 设置为空，其对应的编码值也是 0。也就意味着共享模式下的主载波来源的数据，分离模式下的所有数据，单载波的所有数据以及增强型专用信道上行数据帧中 "上行复用信息" 的编码值均为 0。对于汇聚方的服务无线网络控制器，如图 1 中的无线网络控制器 1 , 是无法区别这 3种情况的，只会根据当前记录的 "增强型专用信道传输承载模式信息" 配置信息进行统一处理。 However, in the "uplink multiplexing information" in the enhanced dedicated channel uplink data frame, the code value corresponding to the primary carrier is 0, and the "uplink multiplexing information" in the enhanced dedicated channel uplink data frame is set to null, which corresponds to The encoded value is also 0. That is to say, the data of the primary carrier source in the shared mode, all the data in the split mode, all the data of the single carrier, and the code value of the "uplink multiplexing information" in the uplink data frame of the enhanced dedicated channel are all 0. For the service provider radio network controller of the aggregator, as shown in Figure 1, the radio network controller 1 cannot distinguish between the three cases, and will only be unified according to the currently recorded "enhanced dedicated channel transmission bearer mode information" configuration information. deal with.

因此，在图 4所示的这个场景下（和图 1的典型场景的差别在于节点 B2 下的小区 3为辅载波频率层上的宏分集小区），依照现有技术的配置方式，以及对应的进行增强型专用信道上行数据帧的传输，无线网络控制器 1 (服务无线网络控制器）给节点 B1增强型专用信道传输承载模式为 "共享模式"，给节点 B2和无线网络控制器 2 (漂移无线网络控制器）不配置任何增强型专用信道传输承载模式 , 会出现如图 5所示： Therefore, in the scenario shown in FIG. 4 (the difference from the typical scenario of FIG. 1 is that the cell 3 under the node B2 is a macro diversity cell on the secondary carrier frequency layer), according to the configuration manner of the prior art, and the corresponding Performing transmission of the enhanced dedicated channel uplink data frame, the radio network controller 1 (Serving Radio Network Controller) gives the Node B1 enhanced dedicated channel transmission bearer mode to "shared mode", to the node B2 and the radio network controller 2 (drift) The radio network controller) does not configure any enhanced dedicated channel transport bearer mode, as shown in Figure 5:

节点 B 1接收了主辅两个载波上的同一个 MAC流- 1 , 放在同一个传输承载 -1上发送给无线网络控制器 1。在图示的 2个增强型专用信道上行数据帧中， "上行复用信息" 分别填写为主载波或者辅载波对应的编码值，来表示为承载此数据帧的载波为主载波或者辅载波。将增强型专用信道上行数据帧传输到无线网络控制器 1 (服务无线网络控制器）。 Node B 1 receives the same MAC stream - 1 on both the primary and secondary carriers and sends it to the radio network controller 1 on the same transmission bearer -1. In the two enhanced dedicated channel uplink data frames shown in the figure, the "uplink multiplexing information" is respectively filled in the code value corresponding to the primary carrier or the secondary carrier, and is represented as the carrier carrying the data frame as the primary carrier or the secondary carrier. The enhanced dedicated channel uplink data frame is transmitted to the radio network controller 1 (Serving Radio Network Controller).

节点 B2和无线网络控制器 2 (漂移无线网络控制器）以及无线网络控制器 2下辖节点 B3 , 以单载波的方式进行增强型专用信道上行数据帧的传输。也就是选择同一个 MAC 流放在同一个传输承载上发送，设置增强型专用信道上行数据帧中的上行复用信息为空，或者增强型专用信道上行数据帧中的上行复用信息被接收方忽略，将增强型专用信道上行数据帧传输到无线网络控制器 1 (服务无线网络控制器）。 The node B2 and the radio network controller 2 (drift radio network controller) and the node B3 of the radio network controller 2 perform the transmission of the enhanced dedicated channel uplink data frame in a single carrier manner. That is, the same MAC stream is selected to be sent on the same transport bearer, and the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel is set to be empty, or the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel is ignored by the receiver. , transmitting the enhanced dedicated channel uplink data frame to the radio network controller 1 (serving radio network controller).

对于无线网络控制器 1 (服务无线网络控制器）而言，其会聚了通过所有的传输途径上来的上行数据。无线网络控制器 1 (服务无线网络控制器）根据当前的记录的 "增强型专用信道传输承载模式信息" 配置信息，也就是 "共享模式" 信息，进行统一处理。无线网络控制器 1 (服务无线网络控制器）将会把从节点 B2和无线网络控制器 2 (漂移无线网络控制器）过来的以单载波的方式的增强型专用信道上行数据帧，其中的 "上行复用信息" 本意为 "单载波" 且编码为 0, 错误识别为同样编码为 0的 "主载波" 含义。也就是无线网络控制器 1 (服务无线网络控制器）将会把从节点 B2和无线网络控制器 2 (漂移无线网络控制器）过来的实际空口来源于辅载波的增强型专用信道上行数据帧，错误识别为空口来源于主载波的增强型专用信道上行数据帧，和从节点 B1过来的实际空口来源于主载波的增强型专用信道上行数据帧，混淆在一起。一旦来源于不同载波接收数据混淆在一起，则无法正常进行重排序以及宏分集合并，所有数据错误，导致实际业务不可用，最终掉网。 For Wireless Network Controller 1 (Serving Radio Network Controller), it aggregates upstream data coming through all transmission paths. The radio network controller 1 (serving the radio network controller) configures information according to the currently recorded "enhanced dedicated channel transmission bearer mode information", that is, "Shared mode" information, unified processing. The radio network controller 1 (serving radio network controller) will transmit the enhanced dedicated channel uplink data frame in a single carrier manner from the node B2 and the radio network controller 2 (drift radio network controller), where " The uplink multiplexing information "meaning "single carrier" and coded to 0, the error is identified as the "main carrier" meaning of the same code 0. That is, the radio network controller 1 (serving radio network controller) will source the actual air interface from the node B2 and the radio network controller 2 (drift radio network controller) from the enhanced dedicated channel uplink data frame of the subcarrier. The erroneous identification is that the air interface is derived from the enhanced dedicated channel uplink data frame of the primary carrier, and the actual air interface from the node B1 is derived from the enhanced dedicated channel uplink data frame of the primary carrier, which is confused. Once the data received from different carriers is confused, the reordering and macro diversity cannot be performed normally, and all data errors are caused, resulting in the actual service being unavailable and eventually falling out of the network.

在图 6所示的场景下（和图 1的典型场景的差别在于节点 B2归属于无线网络控制器 2 ) , 依照现有技术的配置方式，以及对应的进行增强型专用信道上行数据帧的传输，无线网络控制器 1 (服务无线网络控制器）给节点 B1 和无线网络控制器 2 (漂移无线网络控制器）配置增强型专用信道传输承载模式为 "共享模式" , 无线网络控制器 2 (漂移无线网络控制器）给节点 B2 和节点 B3不配置任何增强型专用信道传输承载模式，会出现如图 7所示：节点 B 1接收了主辅两个载波上的同一个 MAC流- 1 , 放在同一个传输承载 -1上发送给无线网络控制器 1。在图示的 2个增强型专用信道上行数据帧中， "上行复用信息" 分别填写为主载波或者辅载波对应的编码值，来表示为承载此数据帧的载波为主载波或者辅载波。将增强型专用信道上行数据帧传输到无线网络控制器 1。 In the scenario shown in FIG. 6 (the difference from the typical scenario of FIG. 1 is that the Node B2 belongs to the radio network controller 2), according to the configuration mode of the prior art, and corresponding transmission of the enhanced dedicated channel uplink data frame. , the radio network controller 1 (serving the radio network controller) configures the enhanced dedicated channel transmission bearer mode to "shared mode" for the node B1 and the radio network controller 2 (drift radio network controller), the radio network controller 2 (drift) The radio network controller does not configure any enhanced dedicated channel transmission bearer mode for node B2 and node B3, as shown in Figure 7: Node B 1 receives the same MAC stream on both the primary and secondary carriers - 1 It is sent to the radio network controller 1 on the same transport bearer-1. In the two enhanced dedicated channel uplink data frames shown in the figure, the "uplink multiplexing information" is respectively filled in the code value corresponding to the primary carrier or the secondary carrier, and is represented as the carrier carrying the data frame as the primary carrier or the secondary carrier. The enhanced dedicated channel uplink data frame is transmitted to the radio network controller 1.

节点 B2和节点 B3 , 以单载波的方式进行增强型专用信道上行数据帧的传输。也就是选择同一个 MAC 流放在同一个传输承载上发送，设置增强型专用信道上行数据帧中的上行复用信息为空，或者增强型专用信道上行数据帧中的上行复用信息被接收方忽略，将增强型专用信道上行数据帧传输到无线网络控制器 2 (漂移无线网络控制器）。 Node B2 and Node B3 perform the transmission of the enhanced dedicated channel uplink data frame in a single carrier manner. That is, the same MAC stream is selected to be sent on the same transport bearer, and the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel is set to be empty, or the uplink multiplexing information in the uplink data frame of the enhanced dedicated channel is ignored by the receiver. , transmitting the enhanced dedicated channel uplink data frame to the radio network controller 2 (drift radio network controller).

无线网络控制器 2处于漂移无线网络控制器的角色，只能够透明转发从节点 B2和节点 B3接收的增强型专用信道上行数据帧至无线网络控制器 1。无线网络控制器 2无法对从节点 B2和节点 B3接收的增强型专用信道上行数据帧的内容进行任何更改。所以在 IUR接口上传输的增强型专用信道上行数据帧的 "上行复用信息" 均为空且编码为 0。 The radio network controller 2 is in the role of a drift radio network controller and can only transparently forward the enhanced dedicated channel uplink data frames received from the Node B2 and the Node B3 to the radio network controller 1. The number of uplinks of the enhanced dedicated channel that the radio network controller 2 cannot receive from the node B2 and the node B3 Make any changes based on the contents of the frame. Therefore, the "uplink multiplexing information" of the enhanced dedicated channel uplink data frame transmitted on the IUR interface is empty and coded to zero.

对于无线网络控制器 1 (服务无线网络控制器）而言，其会聚了通过所有的传输途径上来的上行数据。无线网络控制器 1 (服务无线网络控制器）根据当前的记录的 "增强型专用信道传输承载模式信息" 配置信息，也就是 "共享模式" 信息，进行统一处理。无线网络控制器 1 (服务无线网络控制器）将会把从无线网络控制器 2 (漂移无线网络控制器）转发过来的以单载波的方式的增强型专用信道上行数据帧，其中的 "上行复用信息"本意为 "单载波" 且编码为 0, 错误识别为同样编码为 0的 "主载波" 含义。也就是无线网络控制器 1 (服务无线网络控制器）将会把无线网络控制器 2 (漂移无线网络控制器）转发过来的实际空口来源于主载波（节点 B2 )和辅载波（节点 B3 ) 的所有的增强型专用信道上行数据帧，均错误识别为空口来源于主载波的增强型专用信道上行数据帧，和从节点 B1过来的实际空口来源于主载波的增强型专用信道上行数据帧，混淆在一起。一旦来源于不同载波接收数据混淆在一起，则无法正常进行重排序以及宏分集合并，所有数据错误，导致实际业务不可用，最终掉网。 For Wireless Network Controller 1 (Serving Radio Network Controller), it aggregates upstream data over all transmission paths. The radio network controller 1 (serving radio network controller) performs unified processing according to the currently recorded "enhanced dedicated channel transmission bearer mode information" configuration information, that is, "shared mode" information. The radio network controller 1 (serving radio network controller) will forward the enhanced dedicated channel uplink data frame in a single carrier manner from the radio network controller 2 (drift radio network controller), wherein "upward complex" The information "intended to be "single carrier" and coded to 0, the error is identified as the "main carrier" meaning of the same code 0. That is, the actual air interface forwarded by the radio network controller 1 (the serving radio network controller) from the radio network controller 2 (the drift radio network controller) is derived from the primary carrier (node B2) and the secondary carrier (node B3). All the enhanced dedicated channel uplink data frames are erroneously identified as the enhanced dedicated channel uplink data frame from the primary carrier, and the actual air interface from the node B1 is derived from the enhanced dedicated channel uplink data frame of the primary carrier. Together. Once the data received from different carriers is confusing together, the reordering and macro diversity cannot be performed normally, and all data errors are caused, resulting in the actual service being unavailable and eventually falling out of the network.

综上所述，现有技术中的配置方式没有仔细考虑到所有可能出现的场景实现，因此，可能会出现来源于不同载波接收数据混淆在一起的问题，无线网络控制器无法区别来源于主载波接收数据还是来源于辅载波接收数据，也就无法正常进行重排序以及宏分集合并，所有数据错误，导致实际业务不可用，最终掉网。 In summary, the configuration in the prior art does not carefully consider all possible scenario implementations. Therefore, there may be a problem that the received data from different carriers is confused. The wireless network controller cannot distinguish the primary carrier. The received data is still derived from the secondary carrier receiving data, and the reordering and macro diversity are not performed normally, and all the data errors are caused, so that the actual service is unavailable, and eventually the network is dropped.

The controller notifies the transmission bearer mode information of the enhanced dedicated channel configured by the Node B, and the Node B or the drift radio network controller performs the transmission of the enhanced dedicated channel uplink data frame according to the acquired transmission bearer mode information of the enhanced dedicated channel. The Node B or the drift radio network controller carries the carrier carrying the uplink data in the transmitted uplink data frame when the enhanced dedicated channel transmission bearer mode acquired by the Node B or the drift radio network controller is the shared mode. The carrier identifier, so that the serving network controller can obtain the carrier identifier from the received uplink data, so as to know which carrier the uplink data is derived from, Therefore, the problem that the received data from different carriers is confusing in each scenario and the actual service is unavailable is available, and the existing dual-carrier high-speed uplink packet access technology is unavailable.

下面结合附图对本发明所述技术方案的实施作进一步的详细描述：一种强型专用信道传输上行数据的***，至少包括服务无线网络控制器和节点 B。 The implementation of the technical solution of the present invention is further described in detail below with reference to the accompanying drawings. A system for transmitting uplink data by a strong dedicated channel includes at least a serving radio network controller and a node B.

在其他应用场景中，在建立多载波增强型专用信道小区时，服务无线网络控制器还用于将通知节点 B所述多载波增强型专用信道小区中用于承载上行数据的载波的载波标识信息，这样，当增强型专用信道的传输承载模式为共享模式时，节点 B在所传输的上行数据中携带所接收的载波标识信息即可，其中，服务无线网络控制器可以通过一条消息将增强型专用信道的传输承载模式信息和承载上行数据的载波的载波标识信息同时下发给节点 B, 也可以通过不同的消息，将增强型专用信道的传输承载模式信息和承载上行数据的载波的载波标识信息分别下发给节点 B。 In other application scenarios, when establishing a multi-carrier enhanced dedicated channel cell, the serving radio network controller is further configured to notify the Node B of the carrier identification information of the carrier used to carry the uplink data in the multi-carrier enhanced dedicated channel cell. In this way, when the transmission bearer mode of the enhanced dedicated channel is the shared mode, the Node B may carry the received carrier identification information in the transmitted uplink data, where the serving radio network controller may enhance the type through a message. The transmission bearer mode information of the dedicated channel and the carrier identification information of the carrier carrying the uplink data are simultaneously sent to the Node B, and the transmission bearer mode information of the enhanced dedicated channel and the carrier identifier of the carrier carrying the uplink data may be transmitted through different messages. The information is sent to Node B.

下面介绍上述***，通过增强型专用信道传输上行数据的具体过程，如图 8所示，包括以下步骤： The following describes the specific process of the above system for transmitting uplink data through an enhanced dedicated channel, such as As shown in Figure 8, the following steps are included:

步骤 800: 针对使用多载波高速上行分组接入技术的终端，节点 B或漂移无线网络控制器建立多载波增强型专用信道小区时，服务无线网络控制器将通知节点 B该小区中增强型专用信道的传输承载模式信息； Step 800: When a multi-carrier enhanced dedicated channel cell is established for a terminal using a multi-carrier high-speed uplink packet access technology, the serving radio network controller notifies the node B of the enhanced dedicated channel in the cell. Transmission bearer mode information;

其中，服务无线网络控制器将直接通知节点 B, 或者通过漂移无线网络控制器通知节点 B增强型专用信道传输承载模式信息； The serving radio network controller directly notifies the node B, or notifies the node B of the enhanced dedicated channel transmission bearer mode information by using the drift radio network controller;

"多载波增强型专用信道小区" 是指多载波中其一载波的上行方向使用增强型专用信道的小区，也就是说在增强型专用信道小区中，该小区对应的载波为多载波中的任一载波，具体地，多载波增强型专用信道小区包括主载波增强型专用信道小区、辅载波增强型专用信道小区、第三载波增强型专用信道小区等等。 The "multi-carrier enhanced dedicated channel cell" refers to a cell in which the enhanced dedicated channel is used in the uplink direction of one of the multiple carriers, that is, in the enhanced dedicated channel cell, the carrier corresponding to the cell is any of the multiple carriers. A carrier, specifically, a multi-carrier enhanced dedicated channel cell includes a primary carrier enhanced dedicated channel cell, a secondary carrier enhanced dedicated channel cell, a third carrier enhanced dedicated channel cell, and the like.

"增强型专用信道传输承载模式信息" 包括 "共享模式" 和 "分离模式" 。其中： "共享模式" 是指在所有上行载波上接收的同一个 MAC 流放在同一个传输承载上发送； "分离模式" 是指在从不同的上行载波上接收的每一个 MAC流放在不同的传输承载上发送； "Enhanced Dedicated Channel Transport Bearer Mode Information" includes "Shared Mode" and "Separate Mode". Where: "shared mode" means that the same MAC stream received on all uplink carriers is sent on the same transport bearer; "separate mode" means that each MAC stream received on a different uplink carrier is placed in a different transmission. Send on bearer;

建立多载波增强型专用信道小区的过程是指无线链路建立过程，无线链路建立过程中服务无线网络控制器使用 "无线链路建立请求" 信令将增强型专用信道的传输承载模式信息发送给节点 B。 The process of establishing a multi-carrier enhanced dedicated channel cell refers to a radio link establishment process in which a serving radio network controller transmits a transmission bearer mode information of an enhanced dedicated channel using a "radio link setup request" signaling during a radio link setup process. Give node B.

步骤 810: 节点 B获得增强型专用信道的传输承载模式信息，并依照所获取的增强型专用信道的传输承载模式信息进行增强型专用信道上行数据帧的传输，其中，当增强型专用信道的传输承载模式是使用 "共享模式" 时，节点 B在上行数据帧中携带承载该上行数据的载波的载波标识信息； Step 810: The Node B obtains the transmission bearer mode information of the enhanced dedicated channel, and performs the transmission of the enhanced dedicated channel uplink data frame according to the acquired transmission bearer mode information of the enhanced dedicated channel, where the enhanced dedicated channel is transmitted. When the bearer mode is the "shared mode", the Node B carries the carrier identification information of the carrier carrying the uplink data in the uplink data frame;

其中，当所获取的增强型专用信道的传输承载模式是使用 "分离模式" 时，节点 B将增强型专用信道上行数据帧中的上行复用信息设置为空，或者增强型专用信道上行数据帧中的上行复用信息被接收方忽略；当所获取的增强型专用信道的传输承载模式是使用 "共享模式" 时，节点 B在上行数据帧中携带承载该上行数据的载波的载波标识信息的具体方式为：将增强型专用信道上行数据帧中的上行复用信息信元填写为承载此数据帧的载波的载波标识。对于双载波，在上行复用信元中所填写的载波标识可以是主载波或者辅载波（也可以是第一载波或第二载波）；对于三载波，在上行复用信元中所填写的载波标识可以是主载波、第二载波或第三载波；对于四载波，在上行复用信元中所填写的载波标识可以是主载波、第二载波、第三载波或第四载波。 Wherein, when the acquired transmission bearer mode of the enhanced dedicated channel is using the "separation mode", the Node B sets the uplink multiplexing information in the uplink channel of the enhanced dedicated channel to be empty, or in the uplink data frame of the enhanced dedicated channel. The uplink multiplexing information is ignored by the receiver; when the acquired transmission bearer mode of the enhanced dedicated channel is the "shared mode", the specific manner in which the Node B carries the carrier identification information of the carrier carrying the uplink data in the uplink data frame For: filling the uplink multiplexing information cell in the enhanced dedicated channel uplink data frame into the carrier identifier of the carrier carrying the data frame Knowledge. For the dual carrier, the carrier identifier filled in the uplink multiplexed cell may be a primary carrier or a secondary carrier (which may also be a first carrier or a second carrier); for the three carriers, filled in the uplink multiplexed cell The carrier identifier may be a primary carrier, a second carrier, or a third carrier. For four carriers, the carrier identifier filled in the uplink multiplexed cell may be a primary carrier, a second carrier, a third carrier, or a fourth carrier.

当增强型专用信道的传输承载模式是使用 "共享模式" 时，节点 B选择所有上行载波上接收的同一个 MAC 流放在一个传输承载上发送；当增强型专用信道的传输承载模式是使用 "分离模式" 时，节点 B选择不同的上行载波上接收的每一个 MAC流放在不同的传输承载上发送； When the transmission bearer mode of the enhanced dedicated channel is "shared mode", the Node B selects the same MAC stream received on all uplink carriers to be transmitted on one transmission bearer; when the transmission mode of the enhanced dedicated channel is "separated" In the mode, the Node B selects each MAC stream received on a different uplink carrier to be sent on a different transport bearer;

增强型专用信道上行数据帧"是指类型 2的增强型专用信道上行数据帧，也就是用于多载波技术的数据帧类型； The enhanced dedicated channel uplink data frame "refers to the type 2 enhanced dedicated channel uplink data frame, that is, the data frame type used for the multi-carrier technology;

节点 B应用所获得的增强型专用信道传输承载模式信息于自身下辖的多载波的各个频率层上的增强型专用信道小区，进行增强型专用信道上行数据帧的传输。 The Node B applies the enhanced dedicated channel transmission bearer mode information to the enhanced dedicated channel cell on each frequency layer of the multi-carrier under its own control, and performs the transmission of the enhanced dedicated channel uplink data frame.

步骤 820: 服务无线网络控制器接收节点 B发送的增强型专用信道上行数据帧，根据该增强型专用信道的传输承载模式进行相应的操作，最终可以区分来源于不同载波的接收数据； Step 820: The serving radio network controller receives the enhanced dedicated channel uplink data frame sent by the node B, performs corresponding operations according to the transmission bearer mode of the enhanced dedicated channel, and finally can distinguish the received data from different carriers.

其中，当该增强型专用信道的传输承载模式为共享模式时，服务无线网络控制器读取所接收的上行数据帧的 "上行复用信息" ，以获取承载该上行数据的载波标识信息，即确定该上行数据是来源于哪个载波的； The serving radio network controller reads the "uplink multiplexing information" of the received uplink data frame to obtain the carrier identification information that carries the uplink data, that is, when the transmission bearer mode of the enhanced dedicated channel is the shared mode, that is, Determining which carrier the uplink data is derived from;

当该增强型专用信道的传输承载模式为分离模式时 , 服务无线网络控制器即可通过传输承载唯一地确定承载该上行数据的载波，即确定该上行数据是来源于哪个载波的。 When the transmission bearer mode of the enhanced dedicated channel is the split mode, the serving radio network controller can uniquely determine the carrier carrying the uplink data through the transmission bearer, that is, determine which carrier the uplink data is derived from.

在其他应用场景中，在建立多载波增强型专用信道小区时，服务无线网络控制器还可以将通知节点 B所述多载波增强型专用信道小区中用于承载上行数据的载波的载波标识信息，这样，当增强型专用信道的传输承载模式为共享模式时，节点 B在所传输的上行数据中携带所接收的载波标识信息即可，其中，服务无线网络控制器可以通过一条消息将增强型专用信道的传输承载模式信息和承载上行数据的载波的载波标识信息同时下发给节点 B, 也可以通过不同的消息，将增强型专用信道的传输承载模式信息和承载上行数据的载波的载波标识信息分别下发给节点 B。 In other application scenarios, when establishing a multi-carrier enhanced dedicated channel cell, the serving radio network controller may further notify the Node B of the carrier identification information of the carrier used to carry the uplink data in the multi-carrier enhanced dedicated channel cell. In this way, when the transmission bearer mode of the enhanced dedicated channel is the shared mode, the Node B may carry the received carrier identification information in the transmitted uplink data, where the serving radio network controller may use the enhanced dedicated mode by using a message. Channel transmission bearer The mode information and the carrier identification information of the carrier carrying the uplink data are simultaneously sent to the node B, and the transmission bearer mode information of the enhanced dedicated channel and the carrier identification information of the carrier carrying the uplink data are respectively sent to the different messages. Node B.

下面结合具体应用场景，详细说明上述过程。 The above process will be described in detail below in conjunction with specific application scenarios.
