[0004] 第二层包括各种层,诸如MAC、RLC、PDCP和BMC层。 [0004] The second layer includes various layers, such as MAC, RLC, PDCP and BMC layers. 首先,介质访问控制(MAC)层执行从各种逻辑信道到各种传输信道的映射,并且通过将若干个逻辑信道映射到单个传输信道上来执行逻辑信道复用。 First, medium access control (MAC) layer performs various logical channels to various transport channels from the channel map and by mapping several logical channels to a single transport channel logical channel multiplexing is performed. MAC层经由逻辑信道连接到称作无线链路控制(RLC)层的上层。 MAC layer is connected to an upper layer called a radio link control (RLC) layer via a logical channel. 根据所发送的信息的类型,将逻辑信道划分成发送控制面的信息的控制信道和发送用户面的信息的业务信道。 The type of information being transmitted, the transmission information is divided into logical control plane information a traffic channel and the control channel transmitting user plane. 根据要管理的传输信道的类型,可将MAC层划分成MAC-b子层、 MAC-d子层、MAC-c/sh子层、MAC-hs子层和MAC_e子层。 According to the type of transport channel to be managed, MAC layer can be divided into a MAC-b sublayer, MAC-d sub-layer, MAC-c / sh sub-layer, MAC-hs sublayer and sublayer MAC_e. MAC_b子层管理广播信道(BCH), 该广播信道是处理对系统信息的广播的传输信道。 MAC_b sublayer manages a broadcast channel (BCH), the broadcast channel is a transport channel handling the broadcasting of system information. MAC-c/sh子层管理公共传输信道,诸如前向接入信道(FACH)或下行共享信道(DSCH),该公共传输信道由多个终端共享。 MAC-c / sh sublayer manages common transport channels such as a forward access channel (FACH) or a downlink shared channel (DSCH), the common transport channel shared by several terminals. MAC-d子层管理专用信道(DCH),该专用信道是用于特定终端的专用传输信道。 MAC-d sublayer manages a dedicated channel (DCH), the dedicated channel is a dedicated transport channel for a specific terminal. 此外,为了支持上行/下行高速数据传输,MAC-hs子层管理高速下行共享信道(HS-DSCH),该高速下行共享信道是用于高速下行数据传输的传输信道。 Further, in order to support uplink / downlink high speed data transmission, MAC-hs sublayer manages a high-speed downlink shared channel (HS-DSCH), high speed downlink shared channel which is a downlink transport channel for high speed data transmission.

[0005] 无线资源控制(RLC)层用于确保各个无线承载(RB)及数据传输所要求的各种QoS (Quality of service,服务质量)。 [0005] Radio Resource Control (RLC) layer to ensure that the various QoS (Quality of service, QoS) of each radio bearer (RB) and data required for transmission. 各个RB具有一个或两个独立的RLC实体,以针对各个RB确保唯一的QoS,并且RLC层提供了三种运行模式,即,TM(Transparent Mode,透明模式)、UM (Unacknowledged Mode,不确认模式)和AM (Acknowledged Mode,确认模式),以支持各种QoS。 Each RB having one or two independent RLC entities for each RB in order to ensure that only the QoS, and the RLC layer provides three operation modes, i.e., TM (Transparent Mode, Transparent Mode), UM (Unacknowledged Mode, no unacknowledged mode ) and AM (Acknowledged mode, acknowledged mode) to support various QoS. 此外,RLC层将从上层接收到的数据进行分段和/或串联、以调整数据尺寸,使得下层能够将该数据合适地发送给无线接口。 Further, the RLC layer from an upper layer of the received data segment and / or in series to adjust the data size, so that the lower layer can be suitably transmit the data to the radio interface.

[0006] PDCP层位于RLC层之上。 [0006] PDCP layer is located above the RLC layer. PDCP层执行用于减小不必要的控制信息的报头压缩功能,使得能够经由带宽较小的无线接口来高效地发送采用互联网协议(IP)分组(诸如IPv4 分组或IPv6分组)而传送的数据。 PDCP layer performs for reducing unnecessary control information in a header compression function, making it possible to efficiently transmit using Internet Protocol via a small bandwidth wireless interface (IP) packets (such as IPv4 or IPv6 packets) of data transfer. 因此,报头压缩通过允许数据的报头部分仅发送必要的信息来提高无线接口之间的传输效率。 Thus, header compression to increase the transmission efficiency between radio interfaces by transmitting only the necessary information to allow the header portion of data. 因为报头压缩功能基本上设置在PDCP层中,所以PCDP层仅存在于PS域中。 Because the header compression function is substantially disposed in the PDCP layer, the PCDP layer exists only in the PS domain. 在单个RB中存在单个PDCP实体,以向各个PS业务提供高效的报头压缩功能。 Single PDCP entity exists in a single RB to provide effective header compression function to each PS service.

[0007] 层2 (L2)的广播/组播控制(BMC)层位于RLC层之上。 Broadcast [0007] Layer 2 (L2) is / multicast control (BMC) layer is located above the RLC layer. BMC层对小区广播(CB)消息进行调度,并向位于特定小区或多个小区中的终端广播该CB消息。 The BMC layer of a cell broadcast (CB) message scheduling, and broadcasting a terminal located in a specific cell or a plurality of cells in the CB message.

[0008] 位于层3最低部的无线资源控制(RRC)层仅定义在控制面中。 [0008] positioned a radio resource control (RRC) 3 the lowest portion of the layer defined only in the control plane. RRC层用于针对无线承载(RB)的建立(配置)、重新设置及释放相关联地对层1和层2的参数进行控制,并对逻辑信道、传输信道和物理信道进行控制。 The RRC layer is used for establishing the radio bearer (RB) (configuration), and reset the parameters in association with release layers 1 and 2 is controlled, and the logical channels, transport channels and the physical control channel. 这里,RB是指由无线协议的层1和层2所提供的、用于在移动终端与UTRAN间传送数据的逻辑通路。 Here, RB is defined by the radio protocol layers 1 and 2 provided for a logical channel for transferring data between the mobile terminal and the UTRAN. 通常,RB的建立是指以下过程,即, 规定提供特定数据业务所需的无线协议层及信道的特征,并且设置相应的详细参数和操作方法。 Typically, the establishment of the RB refers to the process, i.e., to provide a predetermined radio protocol layers and the characteristics desired channel specific data service, and setting the respective detailed parameters and operation methods.

[0009] 宽带码分多址(WCDMA)系统采用高速下行分组接入(HSDPA)和高速上行分组接入(HUSPA)技术。 [0009] Wideband CDMA (WCDMA) system uses high-speed downlink packet access (HSDPA) and High Speed ​​Uplink Packet Access (HUSPA) technology. 具体而言,采用这两种技术来有效地支持分组交换(PS)业务。 Specifically, using these two techniques to efficiently support packet switched (PS) service. HSDPA和HSUPA 也称作HSPA。 HSDPA and HSUPA are also known as HSPA.

[0010] 电路交换(CS)方案是通过在发送侧与接收侧之间建立通信电路来交换数据的方案。 [0010] Circuit Switched (CS) scheme is a scheme of exchanging data by establishing communication between a transmission circuit side and the receiving side. 在CS方案中,预先在期望彼此进行通信的两个站点之间设置专用通信通路,并且该专用通信通路包括用于相继地连接各个节点的链路。 In the CS scheme, advance is desired to provide a dedicated communication path between the two stations communicate with each other, and the path comprises a dedicated communication links for sequentially connecting each node. 各个物理链路由单个信道进行连接,因此,各个物理链路能够适当且容易地用在数据交换中,这需要相对无缝的流,诸如电话、传感器、遥测输入等。 Respective physical links connected by a single channel, and therefore, each of the physical link can be properly and easily used in the data exchange, which requires relatively seamless stream, such as a telephone, sensors, telemetry and other inputs. 在数据传输期间,CS方案经由所建立的通信电路来传输数据。 During data transfer, CS scheme to transmit data via the established communication circuit. 因此,这适于发送较大数据量或较长消息(例如,文件传输)时。 Therefore, it is suitable for transmitting large amounts of data or relatively long messages (e.g., file transfer) when. 时分电路交换采用了数字通信电路中的数字交换技术及脉冲编码调制的复用,由此对于高质量的高速数据传输非常高效。 Time division circuit-switched communication circuits using digital technology and digital switching multiplexed pulse code modulation, whereby for high speed data transmission is very efficient. 在此方案中,在两个端点中的各个端点之间分配了专用(固定)物理电路,由此使得从生成数据的时间点至开始数据传输的时间点之间的传输延迟最小化。 In this scenario, between the two end points of the various endpoints allocated a dedicated (fixed) physical circuitry, whereby the transmission time between a time point generated from the data points to the start of data transmission delay minimization. 此外,因为使用了专用(固定)电路,所以,在各个数据中不存在传输次序反向现象(transmission order reversal phenomenon)。 Further, since the dedicated (fixed) circuit, so that the reverse phenomenon does not transmit the order (transmission order reversal phenomenon) in the presence of the respective data.

[0011] 分组交换(PS)方案是在发送侧分组交换机中将具有特定长度的数据传输单元存储为分组格式的方案。 [0011] Packet Switched (PS) scheme is a transmission scheme having a packet switch in the side of a specific length stored as data transmission units of the packet format. PS方案根据接收侧的地址来选择适当的通信通路,然后,将其发送给接收侧分组交换机。 PS scheme to select the appropriate communication paths according to the reception side address, then sends it to the packet switch receiving side. 在PS方案中,按照长度较短的数据块单元(称作“分组”)来发送数据。 In PS embodiment according to a shorter length unit of data block (referred to as "packet") to send data. 通常,分组的长度被限制为大约1000个字节。 Typically, the packet length is limited to about 1000 bytes. 各个分组由表示用户数据的部分和表示分组的控制信息的部分组成。 Represented by a portion of each packet of user data and control information packet representing part of the composition. 这里,分组的控制信息应当至少包括在网络内设置该分组的通路所需要的信息,以使得能够将该分组发送至接收侧。 Here, the control information packet should include at least the setting information required for packet path within the network, so that the packet can be transmitted to the receiving side. 一旦各个节点经由传输通路接收到分组,则首先存储这些分组,然后将其发送至下一个节点。 Once each node receives a packet via the transmission path, the first store these packets, and then sends it to the next node. 继续这种存储过程、直到将分组传送至接收侧为止,接着,重复对下一个节点的传输处理。 This stored procedure continues until the packet transfer until the receiving side, then the transmission process is repeated for the next node. 在此方案中,特定终端并不持续地占据特定通路,相反,只在需要的时候占据并使用特定通路,由此使得电路的使用效率最大化。 In this embodiment, a particular terminal does not continuously occupies a specific path, contrast, and specific passages occupy only when needed, so that thereby maximize efficient use of the circuit. 此外,可以通过不同通路来发送各个数据单元,因此,各个数据所经历的传输延迟量彼此不同。 Further, each data unit may be transmitted through different paths, therefore, the amount of transmission delay experienced by individual data different from each other.

[0012] 近来,开发了多种移动通信业务,以使得支持分组业务(诸如互联网浏览等)的效率最大化。 [0012] Recently, the development of a variety of mobile communication services, so that support packet services (such as Internet browsing, etc.) to maximize efficiency. 在这些移动通信业务中,语音通信业务被视为移动通信中最重要的业务,并且主要通过电路交换业务来提供语音通信业务。 In the mobile communication service, a voice communication service in a mobile communication are considered as the most important business, and mainly provide voice communication service through a circuit switched service.

[0013] 当前,UMTS系统基于对CS业务进行了优化的R99版本WCDMA,另外地采用了R5HSDPA和R6HSUPA来支持PS业务。 [0013] The current, UMTS system based on CS business optimized R99 version WCDMA, in addition to using R5HSDPA and R6HSUPA to support PS services. 也就是说,当前系统支持用于CS业务的CS网络和支持PS业务的PS网络这两者。 In other words, the current system supports both CS and CS service network for business support PS PS network. 但是,从网络运营的角度来看,将会出现安装CS网络和PS网络、以及独立地管理这两个网络的成本问题。 However, from the point of view of network operations, network installation CS and PS networks, as well as the cost of the independent management of the two networks will appear.

[0014] 为了解决这个问题,期望只运营PS网络,而逐步地减少对CS网络的支持。 [0014] In order to solve this problem, expect only PS network operators, and gradually reduce support for the CS network. 为此, 需要一种用PS业务来取代全部CS业务的方法,或者一种在PS网络中有效地提供CS业务的方法。 To this end, a need exists for a PS service to replace all CS service method, or a method of providing a CS service in the PS network effectively.

[0015] 具体而言,需要一种在PS网络(即,在采用了HSDPA和HSUPA技术的HSPD网络) 中支持代表CS业务的CS语音业务的方法。 [0015] Specifically, a need for a PS network (i.e., in the network using the HSPD HSDPA and HSUPA technologies) representing the CS service support CS voice service method.

CFN可以是在MAC实体中对MAC SDU进行加密或解密时所使用的序列号值。 CFN sequence number value may be used when the encryption or decryption of the MAC SDU in the MAC entity. 此外,CFN随着时间的增加而增大。 In addition, CFN increases as time increases. 例如,假设CFN在0. 000秒时为0,则CFN在0. 020 秒时CFN变为1,在0.040秒时变为2。 For example, assume that when the CFN is 0 0.000 seconds, then 0.020 seconds when CFN CFN becomes 1, at the time of 0.040 seconds to 2. 在经过特定时间段的各个时刻,CFN增大,而与是否在特定时间点发送数据无关。 At various times after a particular time period, the CFN is increased, regardless of whether the transmission data at specific time points. 在这种情况下,CFN是在经过了特定时间段时而增大的值,而与是否实际发送或接收数据无关。 In this case, the CFN is elapsed a certain period of time sometimes increased value, regardless of whether the actual data transmission or reception. CFN字段表示如下这种CFN :在该CFN处,已经由MAC对TM RLC PDU进行处理,并且该CFN用于在发送实体中进行加密、并且用于在接收实体中进行解密及对序列进行去抖动(de-jittering)。 CFN CFN field which follows: at the CFN, for TM RLC PDU has been processed by the MAC, and the CFN for encrypting the transmitting entity and receiving entity for decrypting the sequence and debounced (de-jittering).

[0040] 这种CFN信息表示定时信息,诸如,生成特定数据的时间点、特定数据从上方实体到达特定实体的时间点、将特定数据发送至下方实体的时间点、将特定数据传送到上方实体的时间点、或者处理特定数据的时间点等。 [0040] This information indicates the CFN timing information, such as data generated specific point in time, arrival time point of a particular data entity specific entity from above, transmits data to the specific point in time downward entity, to transmit data over a particular physical time point, or other point of time the specific data processing. CFN还可以是用于对发送实体和接收实体在特定时刻应当执行的操作进行定义的时间点信息。 CFN may also be used for the operation of transmitting and receiving entities should be performed at a particular time point information defined time.

[0041] 图4是示出了将CS业务应用于基于高速分组接入(HSPA)技术的方法的示例图。 [0041] FIG. 4 is a diagram showing the CS service is applied based on high speed packet access (HSPA) technology, an example of FIG. 如图4所示,MAC实体根据本发明而使用与CFN有关的信息。 4, MAC entity using CFN information relating to the present invention. 也就是说,与现有技术相比, 本发明在HSPA技术中使用CS方案的RLC TM模式,并且在MAC数据块的MAC报头中包括与CFN有关的信息。 That is, compared with the prior art, the present invention uses RLC TM mode CS scheme in HSPA technology, and includes information about the CFN in the MAC header of the MAC data block.

[0042] 通常,当终端(或UE)从非HSPA小区移动到HSPA小区中时,如果CS用户面数据被映射到RLC UM,则需要从RLC TM到RLC UM的无线承载的重新配置。 [0042] Generally, when a terminal (or UE) moves from a non-HSPA HSPA cell to cell, if the CS user plane data is mapped to the RLC UM, it is necessary to reconfigure the RLC UM RLC TM radio bearer. 这里,可以使用RB 释放和RB建立消息来完成RB的重新配置。 Here, you can use the RB release and RB setup message to complete the reconfiguration of RB. RNC需要等待、直到接收到无线承载建立完成(RadioBearer Setup Complete)消息为止,以获得用于加密的STRAT值。 RNC needs to wait until receiving the radio bearer setup is completed (RadioBearer Setup Complete) message to obtain an encrypted value STRAT. 在本发明中,建议将CS用户面数据映射到RLC TM,而不是RLC UM0因此,不需要通过诸如RB释放和RB建立的过程来进行RLC模式转换。 In the present invention, it is proposed to map the CS user plane data to the RLC (TM), instead of RLC UM0 Thus, no conversion is performed by a process such as RLC mode release RB and RB establishment. RRC可以重新配置传输信道类型,而不是转换RLC模式。 RRC may reconfigure the transport channel type, instead of converting the RLC mode. 通过这种方式,可以缩短从非HSPA小区到HSPA小区的切换的过程。 In this manner, it is possible to shorten the process of switching from a non-HSPA HSPA cell to cell. 因为使用同一时间基准,所以这也使得能够在DCH与HSPA之间进行无缝转换。 Because using the same time reference, which also makes it possible to seamlessly switch between a DCH and HSPA.

[0043] 通过在映射到HSPA (MAC-hs、MAC_ehs或E-DCH)的MAC TM报头中包含CFN或与CFN有关的信息,可以在MAC实体中完成针对RLC TM的CS U面数据的加密/解密。 [0043] By mapped to HSPA (MAC-hs, MAC_ehs or E-DCH) in the MAC (TM) header comprising CFN or information related to the CFN, complete CS U-plane data for the RLC TM in the MAC entity encryption / decryption. 这还能消除在使用RLC UM模式时由于分组丢失(或者,尤其是用于未检测到的错误)而导致的、 任何可能的加密不同步(de-synchronization)问题(这在以前已被发现)。 This would also eliminate packet loss when using RLC UM mode (or, in particular for undetected errors) resulting from any possible encryption of sync (de-synchronization) issues (this has been found in the past) .

[0044] 图5是示出了在介质访问控制(MAC)实体中所生成的数据块的示例图。 [0044] FIG. 5 is a diagram illustrating an exemplary data block in a medium access control (MAC) entity generated. 更具体地说,图5示出了在MAC-d中所生成的PDU。 More specifically, FIG. 5 shows a MAC-d PDU is generated in. MAC-PDU可以由MAC报头和MAC业务数据单元(MAC SDU)组成,并且MACSDU可具有可变尺寸。 MAC-PDU may be formed of a MAC header and a MAC service data unit (MAC SDUs) composition, and may have a variable size MACSDU. MAC SDU的尺寸可以取决于RLC PDU的尺寸,RLC PDU的尺寸在建立过程中进行定义。 The MAC SDU size may depend on the size of the RLC PDU, the RLC PDU size is defined in the setup procedure.

[0045] 图5示出的CFN可指示在生成MAC-d PDU时的CFN的值,并且可用于接收侧的去抖动处理。 [0045] FIG. 5 shows the CFN CFN value may indicate when generating a MAC-d PDU, and may be used to dither processing on the receiving side. 这里,抖动是指当将按照均勻时间间隔而连续生成的各个数据块发送至接收侧时、没有按照各个数据块的最初的生成时间间隔到达的现象。 Here, the jitter is a phenomenon when the respective data blocks at uniform time intervals continuously generated during transmission to the receiving side, not in accordance with the initial generation time interval of each data block arrives. 为了解决这个问题,接收侧将接收到的数据块进行重新排列,然后按照特定的时间间隔逐个对重排后的数据块进行处理。 To solve this problem, the receiving side the received data blocks are rearranged according to a specific time interval and then one by one data block rearrangement process. 在本发明中,建议在去抖动过程中,接收侧应当根据CFN的次序(即,CFN信息)(CFN的次序基于包含在接收到的PDU中的定时信息)来对接收到的PDU进行重排,然后,基于CFN 的值、按照特定的时间间隔来对PDU或包含在PDU中的SDU进行处理,这里,去抖动缓冲器可用于去抖动处理。 In the present invention, it is recommended to dithering process, the receiving side shall CFN according to the order (i.e., CFN information) (CFN order based on timing information contained in the received PDU) reordering PDU to be received then, based on the value of the CFN, a specific time interval of SDUs included in the PDU or the PDU is processed, where de-jitter buffer may be used to dither processing. 在上述处理中,只对除了CFN以外的部分进行加密或解密。 In the above processing, only the portion except for the CFN to encrypt or decrypt. 但是,在该处理中,将CFN包含在全部MAC数据块中可能会是一种浪费。 However, in this process, the CFN may be a waste containing all MAC data block. 例如,语音数据是按照每20ms而生成,如果CFN是12比特,则这将覆盖与81秒对应的时间。 For example, voice data is generated at every 20ms, if the CFN is 12 bits, which will cover the time corresponding to 81 seconds. 这么长的CFN造成了无线接口的浪费,因此,在以上处理中,本发明可以在MAC数据块只包括CFN中的较低部分的比特。 So long CFN causes a waste of the radio interface, therefore, in the above process, the present invention may comprise only the lower part of the bits in the CFN MAC data block.

[0046] 根据AMR编解码器(codec)的特性,本发明还支持子流。 [0046] The characteristics of the AMR codec (codec), and the present invention also supports the sub-streams. 3GPP将称作“AMR”的编解码器用于CS语音业务。 3GPP will be referred to "AMR" codec for CS voice services. 在AMR编解码器中,要使用的编解码器的数据速率根据无线环境而可变地变化。 In AMR codec, the codec of the data rate to be used variably changed according to the wireless environment. 具体而言,在AMR编解码器中生成3个数据流A、B和C。 Specifically, the A generates three data streams in the AMR codec, B and C. 因为每次在各个子流中所生成的数据尺寸不同,所以发送侧应当将在各个子流中所生成的数据量有效地通知给接收侧。 Because different in each respective sub-stream generated in data size, the amount of data transmitted in each sub-side stream should be generated in effectively communicated to the receiving side. [0047] 因此,本发明建议在所生成的PDU内包含称为“子流组合索引”的指示符。 [0047] Accordingly, the present invention proposes comprises an indicator called "subflow combination index" is generated in the PDU. 这是由终端和基站预先设置的值,并且用于指示在当前生成的PDU内的A子流、B子流和C子流的各个比特的数量。 This value is set in advance by the terminal and the base station, and for indicating the PDU A in the current sub-stream generated, the number of bits of the respective sub-stream B and C sub-streams. 例如,可将图6所示的子流组合索引应用于本发明。 For example, as shown in FIG. Subflow combination index 6 may be applied to the present invention. 也就是说,每次生成PDU时,发送侧对包含在各个PDU中的各个子流的数据量进行检查,搜索适合于该数据量的组合的索引,然后,通过将该索引包含在PDU中来发送该PDU。 That is, every time the PDU generation, transmission data amount of each side of the sub-streams included in each PDU of the check, searches for a combination of the amount of data in the index, and, by the index contained in a PDU to send the PDU. 接收侧对包含在接收到的PDU 中的子流组合索引进行检查,并根据该索引的指示来提取与来自PDU的各个子流相对应的数量的比特,从而传送给各个子流。 Receiving side subflow combination index included in the received PDU to check in, and extracts the PDU from the respective sub-streams corresponding to the number of bits in accordance with an instruction of the index, so as to transmit to the respective sub-streams.

[0048] 作为另一种方法,根据在AMR中当前定义且允许的、每子流的比特数的组合,并不存在如下这种索引,在该索引中与各个组合中的各个子流对应的数据的总和相同。 [0048] As another method, according to the currently defined in the AMR and allowed combinations of number of bits per sub-streams, there is not such an index, the index in combination with the respective sub-streams corresponding to the respective the sum of the same data. 因此,如果使用了接收到的PDU的索引和尺寸,则可以获知与PDU中的各个子流对应的相应索引和数据量。 Thus, if a PDU size and index received, the corresponding index can be known and the amount of data corresponding to the respective sub-PDU stream. 因此,本发明建议接收侧应当根据接收到的PDU的尺寸、从PDU中提取预先指定数量的比特,并将所提取的比特传送到各个子流。 Accordingly, the present invention proposes a receiving side should be based on the size of the received PDU, extracts a pre-specified number of bits from the PDU, and transmits the extracted bits to the respective sub-streams. 在这种情况下,DPCP PDU可以只包括数据, 而不包括报头。 In this case, DPCP PDU may include only the data, without including a header. 图7是示出了根据本发明的、在对多个子流进行复用时的PDU的格式的示例图。 FIG 7 is a diagram showing, in the format of the PDU when the plurality of sub streams multiplexed example according to the present invention of FIG. 这里,由PDCP实体来完成对多个子流的复用。 Here, the PDCP entity to complete a plurality of sub-multiplex streams.

[0049] 图8是示出了根据本发明的、用于CS域的子流的分组数据汇聚协议(PDCP)子层的结构的示例图。 [0049] FIG. 8 is a diagram illustrating an example of a structure according to FIG., A packet data convergence protocol sub streams to the CS domain according to the invention (PDCP) sublayer. 如果将图8中的PDCP用于传输CS语音,则在各个方向上将PDCP映射到3个TM承载。 If the PDCP in FIG. 8 for CS voice transmission, in the respective directions on PDCP bearers mapped to TM 3. 图8示出了由PDCP实体完成对各个子流的复用的情况。 FIG 8 shows a case where the completion of the PDCP entity for each sub streams multiplexed. 这里,当CS业务经由PDCP实体而接入到基于PS的无线技术(诸如,HSDPA或HSUPA)时,使用复用。 Here, when the PDCP entity via a CS service access to the PS-based wireless technologies (such, HSDPA or HSUPA), the use of multiplexing.

[0050] 各个CS域RAB与一个PDCP实体相关联。 [0050] CS domain each RAB is associated with one PDCP entity. PDCP实体与对应于RAB的子流数量的、 具有透明模式的多个RLC相关联。 PDCP entities corresponding to the number of sub-stream of the RAB, having a plurality of transparent mode RLC associated. 提供CS业务的PDCP实体并不使用报头压缩。 CS provides services PDCP entity does not use header compression.

[0051] 本发明具有的效果在于,通过以下这种操作方法,即,在利用高速下行分组接入(HSDPA)或高速上行分组接入(HSUPA)技术来提供电路交换(CS)业务时,由发送侧发送包含在数据块中的连接帧号,使得接收侧能够按照基准时间来处理接收到的各个数据块,来高效地支持HSPA网络中的CS业务。 [0051] The present invention has an effect that, by this method of operation, i.e., in the high-speed downlink packet access (HSDPA) or High Speed ​​Uplink Packet Access (HSUPA) technology to provide a circuit switched (CS) service, the a the transmitting side transmits a connection frame number in the data block, the reception side can be handled so that each data block according to the received reference time, to efficiently support the CS service in HSPA network.
