技术领域 FIELD

本发明涉及网络通信技术领域,尤其涉及一种CM速率指定方法及系统。 The present invention relates to network communication technologies, and in particular, to a method and system CM specified rate. 背景纟支术 Si background branch surgery

CPRI (Common Protocol Radio Interface)是应用于无线通信系统中的一种通用无线接口协议,负责定义无线设备控制端(REC)与无线设备端(RE)之间的无线基站的关键内部接口。 CPRI (Common Protocol Radio Interface) is used in wireless communication system, a common radio interface protocol, the key internal interface of radio base station responsible for defining between the radio equipment control terminal (REC) and the radio terminal equipment (RE). 制定该标准的目的在于创建一个面向蜂窝基站的开放型市场,从而大幅度地减少长期以来一直与基站设计相伴的庞大的开发工作量和昂贵的成本。 The purpose of the development is to create a standard for open market of cellular base stations, thus significantly reducing long been associated with the base station design accompanied by a huge development effort and expensive cost.

CPRI的成立有助于无线基站配套产品的规范化,使通信设备制造商能够有选择性的购买无线基站子系统,从而提高产品的开发速度,缩短新产品上市时间,并保证产品的丰富性。 Contribute to the establishment of standardized CPRI radio base station supporting products, communications equipment manufacturers can make selective purchase a wireless base station subsystem, thereby increasing the speed of product development, shorten time to market for new products, and to ensure that the richness of the product. 而直接从中获益的是运营商,因为这一规范将提高网络部署的效率。 The direct benefit of operators, as this specification will improve the efficiency of network deployment. CPRI行业合作组织的成立,使基站制造商能够把精力集中在核心技术能力的研发上,并且能够购买统一标准的无线基站子系统。 Founded CPRI industry cooperation organization, the base station manufacturers can focus on the core technology research and development capabilities, and the ability to purchase unified standard wireless base station subsystem. 该组织带来的最主要的益处是,让被引入的新技术得以更快的发展,并且使基站制造商能够为运营商提供更加丰富的产品系列,同时以更短的时间将产品投向市场。 The main benefit of this organization is to bring, so that new technologies are introduced to faster development, and the base station manufacturers to provide a richer product portfolio for operators, while shorter time to market the product. 同时运营商也会受益于更加广泛的产品选择、更加灵活的解决方案和网络部署效率的进一步提高。 At the same time operators will also benefit from a broader product selection, more flexible solutions and further improve the efficiency of network deployment. CPRI的创始企业将齐心致力于开创一个竟争性的移动网络零部件行业,并且通过开放CPRI接口,使整个无线行业受益。 CPRI's founding companies will be united committed to creating a competitive network of mobile parts industry, and through the open CPRI interface that will benefit the entire wireless industry. CPRI将对现有的标准化组织(例如3GPP/3GPP2)起到补充作用, 其开发的通用接口将4皮应用于移动系统的无线基站产品中。 CPRI will existing standardization organization (e.g., 3GPP / 3GPP2) complement, the development of universal interface 4 is applied to the skin of a radio base station products of mobile systems.

图1所示为CPRI链路结构示意图。 Figure 1 shows a schematic view of the structure of the CPRI link.

如图1所示,CPRI协议总体上分为两个部分:REC端和Re端。 As shown in FIG 1, it is divided into two general portions of the CPRI protocol: REC side end and Re. RE处子远端,中间通过光纤、电缆或其他信号传输介质连接。 At the distal end of the sub-RE, intermediate connection through fiber optics, cable or other signal transmission medium. 图中的数据流包舍控制面和数据面的两类数据。 FIG homes packet data flow control and data planes are two types of data.

图2所示为CPRI协议工作状态示意图。 2 shows a schematic view of the operating state CPRI protocol.

如图2所示,CPRI协议在工作的时候,共分为7个状态,分别为: 0状态(Standby)是空闲状态。 2, the CPRI protocol at work, is divided into seven states, namely: 0 state (Standby) is idle. 在这个状态中,协议等待上层指令启动CPRl协议状态机。 In this state, the protocol waits for an instruction to start CPRl upper layer protocol state machine.

1状态(synchronization)是线路速率协商状态,也是同步状态。 1 state (synchronization) is the line rate negotiation state, is synchronized. 在这个状 In this state

达到REC和RE的物理线路收发速率一致。 REC and RE achieve consistent physical line transceivers rate.

2状态(Protoco1 setup)是协议版本号协商状态。 2 state (Protoco1 setup) is the protocol version negotiation. 在这个状态中,要求协议两端REC和RE的CPRI当前协议版本保持一致。 In this state, on both ends of the REC and RE CPRI protocol consistent with the current protocol version.

3状态(CM plane (L2+) setup)是CM速率协商状态。 3 state (CM plane (L2 +) setup) is CM rate negotiation. 在这个状态中,要求REC和RE的高级数据连路控制(HDLC)的收发速率达到一致,也就是控制面的数据速率一致。 In this state, high-level data requirements of the link-REC and RE control (HDLC) transceiver achieve the same speed, which is consistent with the data rate control plane.

4状态(lnterface and vendor specific negotiation)是正常工作状态,表示REC和RE两端的所有参数都已经一致,可以进行正常数据传输。 4 state (lnterface and vendor specific negotiation) is normal, and indicates that all parameters REC and RE have the same ends, normal data transmission can be performed. 就是在这个状态,如果发现有指定的CM速率,就要求使用指定的CM速率。 It is in this state, if there are designated CM rate, requires the use of CM specified rate.

5状态(Operation)和4状态一样,也属于正常工作状态。 5 state (Operation) and 4-state, as is a normal operation state. 受上层软件控制。 Controlled by the upper software.

6状态(Passivelink)是旁路状态。 6 state (Passivelink) is a bypass state. 在这个状态中,不传送HDLC数据。 In this state, the HDLC data is not transmitted. CPRI接口要同时承载数据面和上层控制面的数据(HDLC)。 CPRI interface plane to carry both data and upper layer control plane (HDLC). 为了保证HDLC数据发送、接收的正确性,确保HDLC收发速率的一致性是非常必要的,在CPRI协议层,保证HDLC—致地进行发送、接收的速率称为CM速率。 In order to ensure the HDLC data transmission, reception accuracy to ensure consistency HDLC transceiver rate is necessary, in the CPRI protocol layer, to ensure actuation HDLC- transmitting, receiving rate is called the rate of CM.

CM速率在CPRI链路两端进行匹配时一般采用自动协商的方法,但协议 CM CPRI link rate at both ends to match the general method of auto-negotiation, but the agreement

6规定,无论协商的CM速率是多少,在CPRI协议的四状态(所述的四种状态 6 provides that, no matter how much the rate negotiated CM, in a four-state CPRI protocol (the four states

各为CPRI协议工作的一个阶段,表示链路工作正常的状态表示),如果发现有指定的速率,协议就要应用指定的速率传送HDLC数据。 Each working stage of the CPRI protocol, the link status indicates normal work), it found that if a specified rate, the application must specify the protocol HDLC data rate transmission.

目前直接应用协议指定速率的方法存在一个风险。 Currently there is a risk of direct application protocol method specified rate. 就是一旦上层软件指定了CM速率,如果指定的方法不当造成REC和RE速率不一致,很容易导致HDLC链路断掉。 Once the software is top rate specified CM, if the specified method improper REC and RE inconsistent rate, it can easily lead to HDLC link is broken. 又由于CPRI的远端一般是无人维护,这样可能造成上层协议永远断路,导致系统崩溃。 Also, because the distal end of the CPRI is generally no maintenance, which could cause the upper layer protocol is always open circuit, causing the system to crash. 保证指定速率的可靠性,就变的非常必要。 Ensure the reliability of specified rate, it becomes very necessary. 发明内容 SUMMARY

具体实施方式 Detailed ways

备的速率信息交互为自身指定受无线设备端支持的CM速率;无线设备端进行本地CM速率协商,为自身指定与无线设备控制端CM速率相同的CM速率, 实现无线设备控制端和无线设备端在相同的CM速率下工作。 Rate information exchange apparatus is designated as the self CM rate by wireless device-side support; wireless device side local CM rate negotiation, specify the same radio equipment control terminal CM rate CM rate itself, wireless device control terminal and the wireless device end CM work at the same rate.

具体一点讲,本发明首先需要进入系统正常工作状态,然后进行所述的CM速率指定。 Specific point, the present invention firstly need to enter the system normal operation, then the rate of CM specified.

系统进入正常工作状态前过程为由系统上电开始工作起至系统进入正常工作状态,其包括: The system is powered by the process start work until the system into normal operation before the system into normal operation, including:

当系统上电开始工作,CPRI协议此时处于空闲状态,处于空闲状态的协议等待上层协议发出启动CPRI协议状态机的指令。 When the power to work on the system, this time in an idle state CPRI protocol, the protocol in idle state waiting for the upper layer protocol issues a command to start the CPRI protocol state machine.

CPRI协议接到来自上层协议的CPRI协议启动命令以后,进入线路速率协商状态。 CPRI protocol after receiving the CPRI protocol from the upper-layer protocols boot command, enter the rate negotiation state line. 在此状态中,CPRI协议根据协议规定的线路速率协商机制进行线路速率协商,使REC和RE的物理线路收发速率一致。 In this state, the line rate of the CPRI protocol negotiation line rate negotiation mechanism according to the predetermined protocol to the physical REC and RE line transceiver consistent rate.

REC和RE的物理线路速率协商成功以后,CPRI协议进入协议版本号协商阶段,协商数据传输所使用的CPRI协议的版本号,确定使用相同版本的CPRI协议进行数据传输。 After REC and RE physical line rate negotiation is successful, the CPRI protocol into the protocol version negotiation, the version negotiation CPRI protocol used for data transmission, is determined using the same version of CPRI protocol for data transmission.

10通过版本号的协商,实现REC和RE当前使用的CPRI协议版本保持一致,此时CPRI进入CM速率协商状态。 10 negotiated version number, and the realization of REC RE CPRI protocol version currently in use is consistent, this time into the CM CPRI rate negotiation. CM速率协商成功后,CPRI进入正常工作状态,开始使用CPRI协议进行数据传输。 After the CM rate negotiation is successful, CPRI into normal operation, start using the CPRI protocol for data transmission.

当系统进入正常工作状态后,便可以进行CM速率指定,其指定方法如 When the system enters the normal operating state, the rate of CM can be specified, which specifies such method

下: under:

REC側上层软件向RE侧发送CM速率指定提示消息,该消息中携带欲指定的CM速率; REC-side upper layer software to send a prompt message to the specified rate of CM RE side, to be carried in the message CM specified rate;

当RE侧上层软件接收CM速率指定提示消息,RE侧立即向REC侧回传确认消息,确认消息中携带欲指定的CM速率; When CM RE-side upper layer software receives the rate specified prompt message, transmitted to the RE side REC side immediately return an acknowledgment message, the acknowledgment message carries the CM rate to be specified;

当REC上层软件收到确认消息并且确定确认消息中的欲指定CM速率和自身发送的欲指定CM速率一致后,REC上层软件将该欲指定CM速率指定为REC的CM速率; When REC upper layer software receives the acknowledgment message and determines that the acknowledgment message to be consistent with the specified CM rate to be transmitted by itself and designated CM rate, the upper layer software to be designated REC rate designated CM CM rate of the REC;

在上层软件发出指定提示消息后,REC通过速率协商实现CM速率的指 After issuing the alert message is specified in the upper software, REC achieved by CM rate refers to the rate negotiated

定; set;

在REC侧指定CM速率成功后,REC将该CM速率发送给RE; After specifying the REC side at the success rate of CM, the CM transmission rate to the REC REs;

RE收到新的CM速率以后,发现和当前自身使用的CM速率不匹配,进入CM速率协商状态,进行CM速率协商; RE CM after receiving a new rate, the current rate of discovery and CM does not match their own use, enter CM rate negotiation state, the CM negotiated rate;

因此RE的上层软件发现RE与CPRI链路进入CM速率协商状态,便将REC侧CM速率指定为RE侧的CM速率; Thus upper RE and RE CPRI link discovery software into the CM rate negotiation state, put rate designated REC side CM CM rate RE side;

RE把新配置的CM速率传给REC,用于检验RE与REC的CM速率是否相 The new configuration of the CM RE rate pass REC, REC and RE for testing whether the relative rate of CM

同; with;

CPRI链路两端均在新的指定速率下工作,CM速率指定成功,并告知REC和RE的上层软件,系统恢复正常工作状态。 CPRI both ends of the link are working at the new prescribed rate, CM success rate specified and inform REC and RE of the top software, the system returns to normal operation.

下面将结合本发明具体实施例附图对本发明作详细说明。 The invention will BRIEF following specific embodiments of the invention described in detail. 图3所示为本发明实施例一CPRI进入正常工作状态的流程示意图。 Figure 3 a schematic flow into the normal working state of a CPRI embodiment of the present invention is shown. 步骤31、在系统上电开始工作时,CPRI协议处于空闲状态,协议等待上层指令启动CPRI协议状态机。 Step 31, when the electrical system starts to work on, the CPRI protocol in the idle state, the protocol waits for an instruction to start the upper CPRI protocol state machine. 此时,上层软件应将REC和RE配置为CM速率协商状态,不能配置为指定状态。 In this case, the upper layer software should be configured to CM REC and RE rate negotiation state, it can not be configured for the specified state.

步骤32、在CPRI协议接到上层启动命令以后,进入线路速率协商状态,CPRI协议根据协议规定的线路速率协商机制进行线路速率协商,使REC 和RE的物理线路收发速率一致。 Step 32, after receiving the CPRI protocol upper start command to enter the line rate negotiation state, the CPRI protocol for the line rate negotiation mechanism according to the negotiated agreement predetermined line rate, so the REC and RE transceiver same physical line rate.

线路速率协商的过程包括:CPRI根据协议在REC侧开始向RE发送CM 速率指示,这个CM速率指示代表的CM速率值应该包含于协商CM速率可选值的一个集合中。 Line rate negotiation procedure comprises: CPRI REC starts transmitting side according to the protocol indicated rate REs CM, the CM CM rate representing a rate indicative value set in the negotiation should contain a value of the optional rate CM. 在速率协商的过程中,REC和RE可采用的CM速率可能分别有几种情况。 In the process of the negotiated rate, REC and RE may be employed There are several possible situations CM rate, respectively.

步骤33、线路速率协商成功以后,CPRI协议进入协议版本号协商,协商CPRI版本号。 Step 33, after line rate negotiation is successful, CPRI protocol into the protocol version negotiation, negotiation CPRI version number.

步骤34、通过版本号的协商,使REC和RE所使用的CPRI协议版本保持一致,此时使CPRI协议的链路进入CM速率协商状态。 Step 34, the negotiated version of the REC and RE CPRI protocol version used consistent CPRI protocol at this time that the link rate negotiation state into the CM.

在CM速率协商过程中需实现REC和RE的HDLC收发速率一致; CM rates during the negotiation process required to achieve consistent REC and RE rate of HDLC transceiver;

在CM速率协商过程中上层软件不能指定CM速率; During the consultations, the rate of pelagic CM CM software can not be specified rate;

CM速率协商得到的CM速率取值应在CM速率协商的速率集合内。 CM CM rate negotiated rate of value should be within the set rate CM negotiated rate.

如杲协商成功,CPRI进入状态4 (正常工作状态)。 Gao as successful negotiation, CPRI into a state 4 (normal operation).

步骤35、当CPRI进入正常工作状态,如果系统需要,可以进行CM速率指定操作。 Step 35, when the CPRI into normal operation, if the system requires, CM rate specified operation may be performed.

图4所示为本发明实施例二CPRI在正常工作状态下进行CM速率指定的 FIG 4 is shown for the second embodiment CM CPRI rate under normal operating conditions specified in the invention,

示意图。 schematic diagram.

如图4所示,所述CM速率指定过程包括: 步骤41、在REC侧,上层软件主控指定CM速率。 As shown in the FIG. 4 process designated CM rate comprising: Step 41, the REC side, the upper layer software master CM specified rate. 上层软件要指定速率的时候,为防止HDLC链路断链,不能立即给采用CPRI协议传输数据的链路下达指定提示消息,使REC以指定的CM速率进行数据传输,而是通过指定提示消息将指定速率通过当前的HDLC链路下发给RE,同时开始计时。 When the upper layer software to be prescribed rate, to prevent the HDLC link chain scission, not immediately to transmit data using the CPRI link protocol assigned specified message prompt the REC at the specified CM data transmission rate, but by specifying a prompt message RE specified rate sent by the current HDLC link, and start timing.

步骤42、当RE侧上层软件收到指定提示消息,则RE立即向REC回传确认消息,确认消息由确认帧携带。 Step 42, when the upper layer software receives the RE-side specified message, then immediately return confirmation RE to the REC message, the acknowledgment message carries an acknowledgment frame.

RE在发送回传确认消息时,在该消息中携带着REC发送给RE的CM指定速率。 When RE sends back acknowledgment message carrying the REC message is sent to the CM RE specified rate.

所述确认消息中携带CM速率的数值用于检测CM速率的正确性,防止由于传输过程出错引起REC指定提示消息中CM速率发生改变,导致RE侧收到错误的CM速率;保证REC侧和RE侧支持同一个CM速率。 The acknowledgment message carries the CM accuracy rate for detecting the value of CM rate, to prevent errors caused by transmission designated REC CM prompt occurs at a rate change message, resulting in a CM RE-side receive the error rate; guaranteed REC and RE side CM-side support the same rate.

当RE侧收到指定提示消息后,需要在RE側本地打上一个标签,标记RE 侧即将进行CM速率指定。 When the RE side receives a specified prompt message, you need to be marked with a label on the side of local RE, RE-side mark the upcoming CM rate specified. 若未标记标签,即使RE进入CM速率协商状态,也不为RE配置新的指定速率,以防止RE只要进入CM速率协商状态就乱指定CM速率的情况发生。 If you do not mark the label, even if the rate of RE into the CM negotiation state, nor a new configuration for the specified rate RE, RE in order to prevent just go to the state rate negotiation CM CM chaos specified rate of occurrence.

步骤43、当REC上层软件收到回传确认消息但回传确认消息中的CM速率和自身发送的CM速率不一致,则重新向RE侧发送指定提示消息。 Step 43, when the REC upper layer software receives acknowledgment message back to back but inconsistency acknowledgment message rate CM and CM own transmission rate, the RE sends the re-designated prompt message.

当REC端上层软件在预设置的时间T (根据不同系统,可以调整)没有收到RE的回复消息,则重新发送指定提示消息。 When the upper end of the REC time preset in the software T (different systems can be adjusted in accordance) RE does not receive a reply message, then re-send the specified prompt messages.

如杲重新发送超过N次(根据不同系统要求,可以调整),表示上层HDLC链路异常,放弃CM速率指定,并告警。 As Gao resending exceeds N times (depending on the system requirements, may be adjusted), the upper layer represents the HDLC link error, to give CM specified rate, and alarm.

当REC上层软件收到确认消息并且确定确认消息中的CM速率和自身发松的CM速率一致后,清除计时,上层软件为REC侧指定CM速率。 When REC upper layer software receives the acknowledgment message and determines a rate consistent with the confirmation message CM and CM itself loose hair rate, reset the counter, the upper layer software designated CM rate REC side.

上层软件对REC侧CM速率的指定是由REC侧进入CM速率协商状态后通过CM速率协商得到的。 CM rate negotiated by the designation of the upper layer software REC side CM CM rate is entered by the REC side of rate negotiation state.

步骤44、在CM速率协商结束后,将确认可使用的REC侧CM速率值通过Z.66.0或者Z.194.0 (CPRl链路中的传递CM速率的位置)传给RE。 Step 44, after the CM negotiated rate, the rate that the REC side CM value may be used by Z.66.0 or Z.194.0 (position transfer rate CPRl CM link) to the RE.

步骤45、 RE側接收到REC侧新配置的CM速率以后,发现和当前自身使 After step 45, RE side receives the rate at which new CM configured REC side, and found that the current itself

用的CM速率不同,因此也进入CM速率协商状态,进行CM速率协商。 CM with different rates and, therefore, enter CM rate negotiation state, the CM negotiated rate.

步骤46、 RE的上层软件发现CPRI进入CM速率协商.状态后,将RE的CM Step 46, RE CPRI into the discovery of the top software CM rate negotiation. After the state of the RE CM

速率配置为REC侧新指定的CM速率,在CM速率指定结束后清除RE中的CM The new rate is set to a specified rate of REC side CM, CM remove the RE after the end of the specified rate CM

速率指定标签。 Rate specified label.

为了防止REC或RE内部配置出错,要求上层软件配置完毕后,再回读RE寄存器内的值,检测RE中实际配置的CM速率与RE寄存器内上层软件指定的CM速率是否一致,如杲发现不一致,则重新配置RE侧CM速率,直到速率配置一致为止。 To prevent the REC or RE internal configuration errors, it requires the upper layer software configuration is completed, reads back the value in the register RE, the RE detecting whether the actual configuration of the RE register CM rate specified by the upper software CM same rate, inconsistencies are found as Gao , rE side reconfigure CM rate, up until the same rate configuration.

步骤47、 RE侧也通过Z.66.0或者Z.194.0 (CPRI链路中的传递CM速率的位置)把本地新配置的CM速率传给REC,用于检验RE侧与REC側的CM速率是否相同。 Step 47, RE side or also by Z.66.0 Z.194.0 (CM position transfer rate CPRI link) the local CM newly configured REC pass rate, the rate of testing for CM RE and REC-side is the same side .

步骤48、 49、当CPRI的RE侧、REC侧使用相同的指定CM速率时,CM 速率协商成功,将这一结果分别告知RE侧、REC侧的上层软件,系统进入正常工作状态。 Step 48, 49, when the side of the CPRI RE, the REC side of the same rate specified CM, CM rate negotiation is successful, the results are informed of the RE side, the upper layer software REC side, the system enters the normal operating state.

针对在CM速率指定过程中可能出现的一些特殊情况,其处理方法如 For some special cases may arise in the process of CM specified rate, such that the processing method

下: under:

对于RE来;并,如果待指定的速率在协商速率的集合里面,CM速率协商状态很短时间内就会结束,软件有可能无法识别这个状态。 For RE come; and, if the rate specified in the collection to be negotiated rate which, CM state rate negotiation will end a very short time, the software may not recognize this state. 在无法识别CM速率协商状态的情况下,实际上并不影响链路协商的成功。 Without being able to recognize CM rate negotiation state, in fact, it does not affect the successful link negotiation. 在RE侧本地的标签标定的速率和当前运行的速率已经一致,因为链路不好,重新指定一下对系统没有影响。 RE side has been consistent calibration of a local label rate and the current rate of operation, because of poor links to reassign it has no effect on the system. REC重新再一次指定新的速率的时候,这标签就会被覆盖,图4所示为本发明实施例二CPRI在正常工作状态下进行CM速率指定的示意图。 REC again re-assign a new rate time, this label would be covered, according to a second schematic embodiment of the invention CPRI rate specified for CM in a normal operating state shown in FIG. 4 present. 为了防止在指定速率以后,由于设备一边系统掉电,导致CPRI不工作,或者其他因素导致系统复位,引起一边处于指定状态, 一边处于协商状态,导致 After a specified rate in order to prevent, since the device while the system is powered down, resulting in CPRI does not work, or other factors cause a system reset, causing the side in the specified state, while in the Negotiating state, resulting in

系统永远断路,要求CPRI在进入CM速率协商状态以前,自行消除REC或RE 的指定状态,将其状态改为CM速率协商。 The system will never break, before entering the CM requirements CPRI rate negotiation state, eliminate self-designated status REC or RE will change its status to CM negotiated rate. 上层软件如果要求CPRI工作在指定的CM速率,必须根据CPRI状态的变化,做出相应的响应,即从上述过程中的步骤4开始重新进行CM速率指定过程。 If the upper layer software requirements specified in the CPRI CM work rate, the change must CPRI status, respond accordingly, i.e. from the step 4 of the above process restarts the CM process specified rate.
