Description

一种实现语音并发数据的方法及装置 A method and apparatus for concurrent voice data

技术领域 FIELD

[0001] 本发明涉及语音并发数据技术,特别是指在CDMA2000系统中一种实现语音并发数据的方法及装置。 [0001] The present invention relates to concurrent voice data technology, and particularly to a method and apparatus for concurrent voice data in a CDMA2000 system.

背景技术 Background technique

[0002] CDMA2000系统除了支持基本的语音业务和数据业务以外,还支持并发业务,并发业务是指在同一次呼叫中支持两种或两种以上的业务,比如,语音业务和数据业务并发、或者数据业务和数据业务并发等。 [0002] CDMA2000 system, in addition to supporting basic voice and data services, it also supports concurrent services, concurrent services during the same call means that support two or more services, such as voice and data services concurrently, or data services and data traffic concurrency. 在CDMA2000ReleaSe A的协议标准中支持语音业务和数据业务的并发,通俗的讲,就是让用户一边上网一边打电话的业务,也就是当终端和分组数据交换域有数据传输的同时,可以与另一用户进行语音通信;或者与另一用户进行语音通信的同时,可以发起与分组数据交换域的连接。 Support voice and data services in the protocol standard CDMA2000ReleaSe A concurrent, popular talk, is to let the user side of the Internet side of the phone business, that is, when at the same time and packet switched domain terminal data transmission, it can be another user voice communication; simultaneously or voice communication with another user, can initiate a connection with the exchange of the packet data field.

[0003] 语音并发数据业务呼叫,包括语音并发主叫数据业务呼叫和语音并发被叫数据业务呼叫。 [0003] voice call concurrent data services, including voice calls and data traffic concurrently caller called concurrent voice data service call. 用户在进行文件传输协议(FTP, File Transfer Protocol)数据下载或浏览网页时,依然可以接收来自另一用户的呼叫或主动呼叫另一用户;在进行语音通话时,依然可以进行FTP数据下载或浏览网页,实现了语音通信与数据业务并发。 User during file transfer protocol (FTP, File Transfer Protocol) to download data or browse the Web, you can still receive calls from another user or an active call to another user; during a voice call, you can still download data or browse for FTP page, to achieve voice communication and data services concurrently.

[0004] CDMA2000系统介质访问控制(MAC, Media Access Control)层业务信道的基本信道(FCH, Fundamental Channel)和专用控制信道(DCCH, Dedicated Control Channel)等逻辑信道支持并发业务,系统同时支持语音业务和分组域业务,在呼叫进入逻辑信道后由选择分发单元(SDU, Select Distribute Unit)复用子层完成语音、分组数据、信令巾贞的复用和解复用,逻辑信道FCH和DCCH的帧格式如图1所示,分为主业务数据块、次业务数据块和信令业务数据块。 [0004] CDMA2000 system a media access control (MAC, Media Access Control) fundamental channel traffic channel layer (FCH, Fundamental Channel) and a dedicated control channel (DCCH, Dedicated Control Channel) and other logical channels support concurrent services, system supports voice service and packet domain service after the completion of the call entering the logical channels by the selection distribution unit (SDU, select distribute unit) sublayer voice, packet data, signaling towel Zhen multiplexing and demultiplexing, the FCH and the DCCH logical frame the format shown in Figure 1, divided into a main service data block, the data block and the current service traffic signaling data block. 其中,主要业务数据块和次要数据业务块中既可以放置语音数据也可以放置数据业务的数据,具体放置什么业务是由呼叫建立阶段的点对点协议(PPP,Point-to-Point Protocol)协商确定;信令业务数据块用来复用空口信令;三种业务数据块的大小由协议数据单元(PDU, Protocol Data Unit)Typel和F1DU Type2两种巾贞格式类型决定,PDU Typel和TOU Type2的帧格式分别如图2和图3所示。 Wherein the main service data and the secondary data blocks may be placed in the service block speech data may be placed in data service data, what specific service is placed establishment phase Point to Point Protocol (PPP, Point-to-Point Protocol) call is determined by a negotiation ; signaling traffic multiplexed data block for signaling air interface; three service data block size determined by the protocol data unit (PDU, protocol data unit) Typel and two kinds of towels Chen F1DU Type2 format type, PDU Typel and the TOU Type2 frame formats are shown in Figures 2 and 3. FCH和DCCH都可以支持以上两种H)U Type,使用哪种H)U Type根据呼叫类型在呼叫建立阶段来决定。 FCH and DCCH can support two or more H) U Type, which use H) U Type call set-up phase is determined according to the type of call.

[0005] 现有技术中,在整个语音并发数据业务中,因为语音的实时性要求比较高,系统在逻辑信道复用帧时优先复用语音帧,只有在逻辑信道有空闲时才复用数据业务帧。 [0005] In the prior art, the entire speech concurrent data services, since the real-time requirements of voice is relatively high, the system priority logical channel multiplexing frame by multiplexing speech frames only when an idle logical channels multiplexed data business frames. 在语音并发数据呼叫建立并进入PPP协商阶段,如果用户一直讲话或者处于非常嘈杂的环境下,语音帧一直是全速率帧,语音业务要占用全部的逻辑信道空间,使得逻辑信道FCH和DCCH没有空闲来复用数据业务帧,导致在数据业务呼叫建立阶段中,与终端如手机进行PPP协商的数据业务帧将无法发送到终端,从而导致语音并发数据业务呼叫失败。 Concurrent voice call setup data and enter the PPP negotiation phase, or if a user has to speak in a very noisy environment, speech frame has been full frame rate, voice service to occupy all of the logical space, making the FCH and DCCH logical channel is not idle to multiplex data traffic frame, resulting in call setup phase in data services, such as mobile phones and terminals PPP negotiation of data traffic frames can not be sent to the terminal, causing the voice data concurrent service call fails.

具体实施方式 detailed description

[0036] 本发明的基本思想是:在语音并发数据业务呼叫建立阶段,在逻辑信道优先复用数据业务帧,并发成功后,在逻辑信道上优先复用语音帧,以提高语音并发数据业务的呼叫成功率。 [0036] The basic idea of ​​the invention is that: the voice call setup phase concurrent data services, the logical channel priority in the service multiplexed data frame, the successful concurrent, first multiplexing logical channels in the speech frame, in order to improve the speech concurrent data services call success rate.

[0037] 下面以MAC层的逻辑信道FCH帧格式H)U Typel为例,对本发明所述的方法做以详细描述。 [0037] In the following logical FCH H MAC layer frame format) U Typel an example, the method of the present invention is made to the detailed description. 在FCH上主业务数据块复用语音帧,次业务数据块复用数据业务帧,信令业务数据块复用空口信令。 Main service data blocks on the FCH speech frame multiplexing, time multiplexed data block of service data traffic frame, the signaling traffic multiplexed data block air interface signaling.

[0038] 本发明所提供的实现语音并发数据呼叫的方法,如图4所示,该方法包括以下步骤: [0038] A method for concurrent voice data according to the present invention provides a call, shown in Figure 4, the method comprising the steps of:

[0039] 步骤401 =SDM的复用子层判断当前是否处于语音并发数据呼叫建立阶段并且PPP协商未完成,如果是,则执行步骤402,如果否,则执行步骤405 ; [0039] Step 401 = SDM multiplex sublayer determines whether the current data in a voice call setup phase concurrent PPP negotiation is not completed and, if so, step 402, and if not, step 405 is performed;

[0040] 本步骤中,在语音并发数据呼叫建立阶段,终端会向基站发送语音并发数据呼叫信令,基站将该信令发送到其内部的选择分发复用解复用模块(SDM, Select DistributeMultiplex Demultiplex Module),当SDM的复用子层收到该信令时,则说明当前处于语音并发数据呼叫建立阶段;SDM激活基站内部的无线链路协议(RLP,Radio Link Protocol),通知RLP进行PPP协商检测,其中,当RLP检测到PPP协商完成后通知SDM ;如果SDM的复用子层判定当前处于语音并发数据呼叫建立阶段并且PPP协商未完成,则执行步骤402 ;如果复用子层判定当前没有处于语音并发数据呼叫建立阶段,或者PPP协商完成,则执行步骤405。 [0040] In this step, the call set-up phase concurrent voice data, the data terminal will transmit the voice call signaling to the base station concurrently, the base station transmits the signaling to select a distribution therein multiplexing demultiplexing module (SDM, Select DistributeMultiplex Demultiplex Module), when the SDM multiplex sublayer receives the signaling, then the data currently in the call setup phase concurrent voice; SDM activated inside the base station radio link protocol (RLP, radio link protocol), PPP for notification RLP negotiation detection, wherein, when the RLP detected notification SDM the PPP negotiation is completed; if the SDM multiplex sublayer judged that the current in the voice concurrent data call setup phase and the PPP negotiation is not completed, step 402; if the multiplexing determining sublayer current not in the voice of concurrent data call setup phase, or PPP negotiation is completed, step 405 is performed.

[0041] 步骤402 =SDM的复用子层判断当前是否存在前向信令帧,如果不存在,则执行步骤403,如果存在,则执行步骤405 ; [0041] Step 402 = SDM multiplex sublayer signaling prior to the determination of the current frame exists, if not present, step 403, if present, step 405 is performed;

[0042] 本步骤中,所述前向信令帧,是指从基站发送到终端的用于维持通话状态的信令;该信令在发送过程中,会在SDM中建立一个相应的标志位,用以标识该前向信令帧的存在。 [0042] In this step, the front frame to signaling from the base station is transmitted to the terminal means for maintaining the call signaling state; the signaling will establish a corresponding flag bit in the SDM transmission process , the presence of the previous frame to identify the signaling.

[0043] 步骤403 =SDM的复用子层判断当前语音帧是否全速率并且有数据业务帧;如果是,则执行步骤404 ;如果否,则执行步骤405 ; [0043] Step 403 = SDM multiplex sublayer determines whether the current speech frame and a full rate frame data traffic; if yes, execute step 404; otherwise, step 405 is performed;

[0044] 本步骤中,SDM的复用子层收到语音帧后,会根据帧格式中的相应字段获取该语音帧的传输速率;当SDM收到数据业务帧时,会将该数据业务帧保存,供复用子层查询;如果用户一直讲话或处于非常嘈杂的环境下,则语音帧一直是全速率帧,使得语音业务占用全部的逻辑信道空间,而没有空闲空间复用数据业务帧;如果复用子层判定当前语音帧全速率并且有数据业务帧,则执行步骤404 ;否则,执行步骤405。 [0044] In this step, after the SDM multiplex sublayer receives a speech frame, obtains transmission rate of the speech frame according to the corresponding field of the frame format; SDM is received when data traffic frames, the data traffic frames can save for multiplex sublayer query; or lower if a user has to speak in a very noisy environment, the speech frame has been full frame rate, so that the voice of business space occupied by all logical channels, and there is no free space multiplexing frame data services; If it determined that the current speech frame multiplex sublayer and the full rate data frame service, execute step 404; otherwise, step 405 is performed.

[0045] 步骤404 =SDM将逻辑信道帧复用方式调整为数据业务优先;结束当前流程; [0045] Step 404 = SDM frame multiplexed logical channels is adjusted priority data service; end the current flow;

[0046] 本步骤中,SDM将复用子层的逻辑信道帧复用方式调整为数据业务优先;具体为:SDM根据当前复用帧的内容及长度,即语音帧、数据帧及信令帧的内容及长度,将全速率的语音帧进行降速率或丢弃,在不损伤语音帧的情况下,将逻辑信道中的剩余空间用于传送数据业务帧,在帧格式类型,如I3DU Typel中获取相匹配的帧格式,例如采用图2的Category为14的复用条目,使主业务数据块传输的语音业务为0,而次业务数据块传输的数据业务为168,并将复用帧以该格式通过逻辑信道发送至终端;所述对语音帧进行降速率,一般是将其速率降为全速率的一半。 [0046] In this step, adjusting the SDM multiplexed logical frame multiplexing sublayer way data traffic priority; Specifically: SDM based on the content and length of the current multiplexing frame, i.e. the speech frame, a data frame and a signaling frame content and the length of the full rate speech frame is discarded or down rate, without damaging the speech frame, the remaining space in the logical channel for transmitting traffic data frame, acquires the format type frame, such as in I3DU Typel matches the frame format, for example, using FIG. 2 is a Category multiplexed entry 14, the main service data block transmission of voice traffic is 0, while the second service data block transmission data services 168, and the multiplex frame to the format sent to the terminal through a logical channel; said voice frame drop rate, typically the rate is reduced to half the full-rate. 实际应用中,在语音并发数据呼叫建立阶段,SDM对语音帧进行降速或丢弃的时间,即为用户完成上网拨号的时间,一般在2〜3秒时间内,所以不会对语音帧的传送有较大的损伤。 In practical applications, concurrent voice data in the call setup phase, the SDM or slow down speech frame discard time, which the user complete access dial-up time, generally within 2 to 3 seconds, it will not transmit the speech frames greater damage. 在本实施例中,是以逻辑信道FCH为例,实际应用中,逻辑信道可以单独使用FCH或DCCH,也可以同时使用两个信道来传送数据业务帧。 In the present embodiment, an example is a logical channel FCH, practical applications, the logical channel DCCH or FCH may be used alone, or two may be used simultaneously to transmit data traffic channel frame.

[0047] 步骤405 =SDM将逻辑信道帧复用方式调整为语音业务优先。 [0047] Step 405 = SDM frame multiplexing logical channels for voice traffic priority adjusted.

[0048] 本步骤中,SDM将复用子层的逻辑信道帧复用方式调整为语音业务优先,具体为:SDM根据当前复用帧的内容及长度,即语音帧、数据帧及信令帧的内容及长度,先复用语音帧,然后根据信道剩余空间决定复用数据业务帧的大小,在帧格式类型,如rou Typel中获取相匹配的帧格式,并将复用帧以该格式通过逻辑信道发送至终端。 [0048] In this step, adjusting the SDM multiplexed logical sublayer frame multiplexing mode to voice service priority, specifically: SDM multiplex frame based on the current content and length, i.e. the speech frame, a signaling frame and the data frame the content and length of the first multiplexing speech frame, and then determines the multiplexed data traffic frame size according to a channel remaining space, acquired match the frame format of the frame format type, such as rou Typel, and the multiplexing frame by the format logical channel to the terminal.

[0049] 上述方法中,当PPP协商完成后,即语音并发数据呼叫成功后,就可以启用补充信道(SCH,Supplemental Channel)传送数据业务帧,因此在PPP协商完成后优先复用语音帧,也不会对语音并发数据业务造成影响。 [0049] The above-described method, after the PPP negotiation is completed, i.e., the voice concurrent data call is successful, can enable a supplemental channel (SCH, Supplemental Channel) to transmit data traffic frame, so first multiplexing speech frames after the PPP negotiation is completed, and It will not affect the voice concurrent data services.
