本发明涉及通信领域，特别是指一种微波网元及微波网元间的信息传输方法、装置。The present invention relates to the communication field, in particular to a microwave network element and an information transmission method and device between microwave network elements.
背景技术Background technique
数字微波通信作为现代通信技术的三大传输手段之一，因其自身兼有数字通信和微波通信的方便、灵活等优点，一直在通信领域中起着举足轻重的作用。在现代移动通信系统中无论是移动接入网、移动城域网还是骨干核心网，随处都可以看到数字微波通信设备的身影，特别在应急通信中，数字微波通信更由于其信号品质佳和易于维护而成为一种难于替代的通信手段。随着微波通信设备越来越广泛的应用，也对微波通信设备提出了越来越高的要求。As one of the three major transmission means of modern communication technology, digital microwave communication has always played a pivotal role in the field of communication because of its own advantages of convenience and flexibility of both digital communication and microwave communication. In modern mobile communication systems, whether it is mobile access network, mobile metropolitan area network or backbone core network, digital microwave communication equipment can be seen everywhere. Especially in emergency communication, digital microwave communication is more due to its good signal quality and It is easy to maintain and becomes a means of communication that is difficult to replace. As the microwave communication equipment is more and more widely used, higher and higher requirements are put forward for the microwave communication equipment.
数字微波通信是通过地面视距进行信息传递的，是一种点到点的传输。为了对网络中所有的微波网元进行管理，所有微波网元通过专门的网管通道来建立本网元与其它微波网元之间的网管通道，单个网元既是一个数据源设备，也是一个数据转发设备，它通过网管接口传递的既可以是自己的网管数据也可以是其它微波网元的网管数据。Digital microwave communication transmits information through ground line-of-sight, and is a point-to-point transmission. In order to manage all microwave network elements in the network, all microwave network elements establish a network management channel between this network element and other microwave network elements through a dedicated network management channel. A single network element is not only a data source device, but also a data forwarding device. The device, which transmits its own network management data through the network management interface or the network management data of other microwave network elements.
目前，网管数据都是使用TCP/IP协议传送的，主要有两种方式：第一种方法是网络内所有网元都有一个或多个IP地址，网管存储有网络内所有网元的IP地址信息，当网管需要向某网元发送网管数据时它首先向该网元一个或多个IP地址发送请求消息，接收到该网元发送的应答消息后即于该网元建立连接，然后就可以向该网元传送网管数据。该方法的缺陷是网元的IP地址必须提前设置为指定的一个或几个IP地址，网管只会向这几个IP地址发送网元发现请求消息，若IP地址设置不正确则网管无法与网元建立连接并获取网元信息。第二种方法是主动上报，网元在加电后主动与指定IP地址的网管中心建立通信连接，并上报本网元的所有信息，然后网管中心就可以向该网元下发网管数据了。该方法的缺陷是网元加电后向网元管理系统发送的是socket消息，因此必须知道网元管理系统的IP地址，若网元管理系统的IP地址发生改变则会导致网元无法与网管建立连接。At present, the network management data is transmitted using the TCP/IP protocol. There are two main methods: the first method is that all network elements in the network have one or more IP addresses, and the network management stores the IP addresses of all network elements in the network. Information, when the network management needs to send network management data to a network element, it first sends a request message to one or more IP addresses of the network element, and establishes a connection with the network element after receiving the response message sent by the network element, and then can Send network management data to the network element. The defect of this method is that the IP address of the network element must be set to one or several specified IP addresses in advance, and the network management will only send network element discovery request messages to these IP addresses. The network element establishes a connection and obtains network element information. The second method is to report actively. After the network element is powered on, it actively establishes a communication connection with the network management center with the specified IP address, and reports all the information of the network element, and then the network management center can send the network management data to the network element. The defect of this method is that the socket message is sent to the network element management system after the network element is powered on, so the IP address of the network element management system must be known. If the IP address of the network element management system changes, the network element cannot communicate with the network management system. establish connection.

As shown in Fig. 4, the process of establishing a temporary channel between two adjacent microwave network elements includes the following process:
本实施例中为了区分相邻的两个微波网元，将主动发起建链的微波网元称之为第一微波网元，另一个微波网元称之为第二微波网元，该两个微波网元的结构并无差别。相邻的微波网元之间存在微波无线链路，如图3所示，第一微波网元在上电后，本网元内所有的收发代理模块向临跳信息管理模块进行注册，注册后临跳信息管理模块将本微波网元的网元配置消息101发送给所有注册的收发代理模块，网元配置消息101中包括有本微波网元的网元信息，包括但不限于网元标识、网元名称、设备类型、网元IP、子网掩码、默认网关、MAC(介质访问控制)地址、收发代理模块标识(即收发代理模块的序号)和链路状态等等，收发代理模块将接收到的网元信息保存起来并周期性地向与本收发代理模块有物理连接的微波网元发送建链消息；In this embodiment, in order to distinguish two adjacent microwave network elements, the microwave network element that initiates link establishment is called the first microwave network element, and the other microwave network element is called the second microwave network element. There is no difference in the structure of microwave network elements. There are microwave wireless links between adjacent microwave network elements. As shown in Figure 3, after the first microwave network element is powered on, all the sending and receiving agent modules in this network element register with the temporary jump information management module. The impending jump information management module sends the network element configuration message 101 of the microwave network element to all registered sending and receiving agent modules. The network element configuration message 101 includes the network element information of the microwave network element, including but not limited to the network element identification, Network element name, device type, network element IP, subnet mask, default gateway, MAC (media access control) address, sending and receiving agent module identification (ie, the serial number of the sending and receiving agent module) and link status, etc., the sending and receiving agent module will The received network element information is saved and periodically sends a link establishment message to the microwave network element that is physically connected to the transceiver agent module;
收发代理模块根据本地保存的网元信息构建一条建链消息102，该建链消息中包括但不限于如下内容：The sending and receiving agent module constructs a link building message 102 according to the network element information saved locally, and the link building message includes but is not limited to the following content:

f.收发代理模块标识f. Transceiver agent module identification
i.链路状态i. Link status
构建完建链消息后，收发代理模块周期性地通过与相邻的第二微波网元之间的物理连接向第二微波网元的收发代理模块发送该建链消息，具体地，第一微波网元与第二微波网元之间的物理连接为微波无线链路；After constructing the link establishment message, the transceiver agent module periodically sends the link establishment message to the transceiver agent module of the second microwave network element through the physical connection with the adjacent second microwave network element, specifically, the first microwave network element The physical connection between the network element and the second microwave network element is a microwave wireless link;
第二微波网元的收发代理模块收到该建链消息后，向第一微波网元的收发代理模块回复建链成功消息103，该建链成功消息的格式与建链消息相同，但其中的网元信息填的是第二微波网元的网元信息；After the transceiver agent module of the second microwave network element receives the link establishment message, it replies a link establishment success message 103 to the transceiver agent module of the first microwave network element. The format of the link establishment success message is the same as that of the link establishment message, but the The network element information is filled with the network element information of the second microwave network element;
第一微波网元的收发代理模块收到第二微波网元发送的建链成功消息103后，将第二微波网元的网元信息通过建链上报消息104上报给本微波网元的临跳信息管理模块，临跳信息管理模块将第二微波网元的网元信息保存在本地并标识与第二微波网元的临跳通道状态为连通状态。After receiving the link establishment success message 103 sent by the second microwave network element, the transceiver agent module of the first microwave network element reports the network element information of the second microwave network element to the impending jump of the microwave network element through the link establishment report message 104 The information management module stores the network element information of the second microwave network element locally and identifies the state of the impending channel with the second microwave network element as a connected state.
通过上述流程，第一微波网元与第二微波网元可以获知双方的网元信息，由此建立第一微波网元与第二微波网元之间的临跳通道，该临跳通道的建立基于相邻微波网元之间的物理连接，而不基于TCP/IP协议也无需知道相邻微波网元的任何信息，因此在本微波网元IP配置不正确的情况依然可以与其它微波网元建立通信连接。微波网元可以与所有与自己有物理连接的微波网元建立临跳通道，进行信息交互时可以选择任何一个临跳通道，只要有一个临跳通道能够正常通信，就可通过该临跳通道将信息发送给网络内的其它微波网元。此外，微波网元可以同时使用多个收发代理模与相邻微波网元建立多个临跳通道，这时只要有一个临跳通道正常则两个相邻微波网元间的信息交换不受影响，增加了信息传输的可靠性。Through the above process, the first microwave network element and the second microwave network element can obtain the network element information of both parties, thereby establishing the impending channel between the first microwave network element and the second microwave network element, the establishment of the impending channel Based on the physical connection between adjacent microwave network elements, it is not based on the TCP/IP protocol and does not need to know any information about adjacent microwave network elements. Therefore, if the IP configuration of this microwave network element is incorrect, it can still communicate with other microwave network elements. Establish a communication connection. A microwave network element can establish a temporary channel with all microwave network elements that are physically connected to itself, and can choose any temporary channel when exchanging information. As long as there is a temporary channel that can communicate normally, it can use this temporary channel to The information is sent to other microwave network elements in the network. In addition, the microwave network element can use multiple sending and receiving agent modules to establish multiple temporary jump channels with adjacent microwave network elements. At this time, as long as one temporary jump channel is normal, the information exchange between two adjacent microwave network elements will not be affected. , increasing the reliability of information transmission.
在第二微波网元需要主动与第一微波网元建立临跳通道时，可以采用与上述流程相同的方式建立与第一微波网元之间的临跳通道。When the second microwave network element needs to actively establish an impending channel with the first microwave network element, it can establish an impending channel with the first microwave network element in the same manner as the above process.
图5是本发明实施例临跳数据消息收发的流程示意图，如图5所示，相邻的两个微波网元通过临跳通道传输数据的过程包括以下流程：Fig. 5 is a schematic flow diagram of the sending and receiving of impending data messages according to an embodiment of the present invention. As shown in Fig. 5, the process of transmitting data between two adjacent microwave network elements through the impending channel includes the following flow:
本实施例中为了区分发送端微波网元和接收端微波网元，将发送端的微波网元称之为第一微波网元，接收端的微波网元称之为第二微波网元，该两个微波网元的结构并无差别。在第一微波网元内的任何应用需要向第二微波网元发送数据时首先将数据发送给临跳信息管理模块，临跳信息管理模块首先将该待传输的数据缓存在缓冲区中，若缓冲区已满则根据预先设置的策略选择删除缓冲区内已有的数据或者丢弃新数据。临跳信息管理模块根据该待传输的数据构建数据发送消息201，对该数据发送消息编号，接着查询与目的微波网元相对应的是哪个收发代理模块，若该收发代理模块的临跳通道的状态为连通状态，则将数据发送消息201发送到该收发代理模块，若该收发代理模块的临跳通道的状态不为连通状态则暂不发送；In this embodiment, in order to distinguish the microwave network element at the sending end from the microwave network element at the receiving end, the microwave network element at the sending end is called the first microwave network element, and the microwave network element at the receiving end is called the second microwave network element. There is no difference in the structure of microwave network elements. When any application in the first microwave network element needs to send data to the second microwave network element, it first sends the data to the impending jump information management module, and the impending jump information management module first caches the data to be transmitted in the buffer, if When the buffer is full, the existing data in the buffer will be deleted or new data will be discarded according to the preset strategy. The impending jump information management module constructs a data sending message 201 according to the data to be transmitted, sends a message number to the data, and then inquires which transceiver agent module is corresponding to the destination microwave network element, if the impending jump channel of the transceiver agent module is State is connected state, then data sending message 201 is sent to this transceiver agent module, if the state of the impending channel of this transceiver agent module is not then temporarily not sent for connected state;
收发代理模块收到数据发送消息201后将在该数据发送消息中加入一定的控制信息构建临跳数据消息202并发送给目的微波网元(即第二微波网元)的收发代理模块，接着设置超时等待定时器，若在超时后未收到对该临跳数据消息的接收应答消息则再次发送该临跳数据消息直到连续发送预设次数(具体可以为3次)均未收到接收应答消息则不再发送。如收到该临跳数据消息的接收应答消息203，则构建数据应答消息204向本微波网元(即第一微波网元)的临跳消息管理模块上报已成功接收的数据发送消息的序号，临跳信息管理模块从缓冲区中将已成功接收的数据删掉。After receiving the data transmission message 201, the transceiver agent module will add certain control information in the data transmission message to construct the impending data message 202 and send it to the transceiver agent module of the destination microwave network element (i.e. the second microwave network element), and then set Overtime waiting timer, if the receiving response message of the impending data message is not received after the timeout, then the impending data message is sent again until the preset number of consecutive sendings (specifically, 3 times) does not receive the receiving acknowledgment message will not be sent. As receiving the receiving response message 203 of this imminent jump data message, then construct the data response message 204 and report the sequence number of the data sending message successfully received to the imminent jump message management module of this microwave network element (i.e. the first microwave network element), The impending jump information management module deletes the successfully received data from the buffer.
其中，目的微波网元使用不同的消息号来区别不同类别的临跳数据消息，需要处理某种消息号的临跳数据消息时，首先使用相应注册接口向本地微波网元的临跳消息管理模块进行注册，注册的内容包括消息号和对该消息号的临跳数据消息进行处理的处理函数，注册后临跳信息管理模块将注册的内容保存在一个消息处理注册表中。Among them, the destination microwave network element uses different message numbers to distinguish different types of impending data messages. When it is necessary to process impending data messages of a certain message number, it first uses the corresponding registration interface to register the impending message management module of the local microwave network element. Register. The registered content includes the message number and the processing function for processing the impending data message of the message number. After registration, the impending jump information management module saves the registered content in a message processing registry.
在目的微波网元的收发代理模块接收到从临跳通道发送来的临跳数据消息202后先进行CRC(CyclicRedundancyCheck，循环冗余校验码)校验，若校验成功则在剥除第一微波网元添加的控制信息后向临跳信息管理模块转发该临跳数据消息，如CRC校验失败则丢弃该临跳数据消息。目的微波网元的临跳信息管理模块收到本微波网元的收发代理模块发来的数据接收消息205后通过收发代理模块向对端微波网元返回接收应答消息203告知成功接收到的临跳数据消息的序号，然后检索自身的消息处理注册表，若找到与接收到的临跳数据消息的消息号相同的表项，则使用该表项中的消息处理函数处理接收到的临跳数据消息，若未找到匹配的表项则丢弃该临跳数据消息。Carry out CRC (CyclicRedundancyCheck, Cyclic Redundancy Check Code) check first after receiving the impending jump data message 202 sent from the impending jump channel at the transceiver agent module of the destination microwave network element, if the check is successful, then strip the first After the control information added by the microwave network element, the impending data message is forwarded to the impending information management module, and if the CRC check fails, the impending data message is discarded. The impending jump information management module of the destination microwave network element receives the data receiving message 205 sent by the transceiver agent module of the microwave network element, and then returns a receiving response message 203 to the peer microwave network element through the sending and receiving agent module to inform the successfully received impending jump The serial number of the data message, and then retrieve its own message processing registry, if the entry with the same message number as the received impending data message is found, use the message processing function in the entry to process the received impending data message , if no matching entry is found, the impending data message is discarded.
本实施例中，微波网元在与相邻的微波网元建立临跳通道连接后，可以通过该临跳通道下发网元配置信息(IP地址、网管等)与其它微波网元建立网管通道，然后再使用网管通道与其它微波网元进行数据交互。微波网元还可以直接通过临跳通道与其它微波网元进行数据交互，通信方式灵活。In this embodiment, after a microwave network element establishes a temporary channel connection with an adjacent microwave network element, it can issue network element configuration information (IP address, network management, etc.) through the temporary channel to establish a network management channel with other microwave network elements , and then use the network management channel to exchange data with other microwave network elements. The microwave network element can also directly exchange data with other microwave network elements through the temporary jump channel, and the communication mode is flexible.
图6是本发明实施例临跳通道保活超时断链的流程示意图。如图6所示，两个相邻微波网元之间的临跳通道的保活过程包括以下流程：Fig. 6 is a schematic flow diagram of a link-breaking process of an impending channel keep-alive timeout according to an embodiment of the present invention. As shown in Figure 6, the keep-alive process of the impending channel between two adjacent microwave network elements includes the following process:
临跳通道的通信链路建立以后，微波网元的收发代理模块负责链路状态的维护，收发代理模块每隔固定时间会发送一个心跳信息301给与之相连的对端微波网元的收发代理模块，该心跳消息的格式与建链消息的格式相同，但是心跳消息中链路状态使用了不同的标志表明它为心跳消息而不是建链消息；After the communication link of the impending channel is established, the transceiver agent module of the microwave network element is responsible for the maintenance of the link status, and the transceiver agent module will send a heartbeat message 301 to the transceiver agent of the peer microwave network element connected to it at regular intervals module, the format of the heartbeat message is the same as that of the link establishment message, but the link state in the heartbeat message uses a different flag to indicate that it is a heartbeat message rather than a link establishment message;
发送心跳消息后收发代理模块会设置一个超时定时器，如在超时时间内收到对端微波网元的心跳应答消息302则认为链路状态正常，如超时后未收到对端微波网元的心跳应答消息302则重发心跳消息301，当重发次数达到预设次数仍未收到对端微波网元的心跳应答消息302，则认为临跳通道发生故障，收发代理模块向本地微波网元的临跳信息管理模块发送断链上报消息303告知发生故障的微波网元的网元信息，临跳信息管理模块从本地维护的临跳通道信息中找到相应的网元信息并将与该微波网元之间的临跳通道的状态置为断开状态。After sending the heartbeat message, the sending and receiving agent module will set a timeout timer. If it receives the heartbeat response message 302 from the peer microwave network element within the timeout period, it will consider the link status to be normal. The heartbeat response message 302 resends the heartbeat message 301. When the number of retransmissions reaches the preset number of times and still does not receive the heartbeat response message 302 from the peer microwave network element, it is considered that the impending channel fails, and the sending and receiving agent module sends a message to the local microwave network element. The impending jump information management module sends a broken link report message 303 to inform the network element information of the microwave network element that has failed, and the impending jump information management module finds the corresponding network element information from the locally maintained impending channel information and communicates with the microwave network element The state of the impending channel between elements is set to disconnected.
图7是本发明实施例临跳通道主动断链的流程示意图，如图7所示，两个相邻微波网元之间的临跳通道的断链过程包括以下流程：FIG. 7 is a schematic flow diagram of the active link disconnection of the impending channel according to an embodiment of the present invention. As shown in FIG. 7 , the link breaking process of the impending channel between two adjacent microwave network elements includes the following process:
临跳信息管理模块通过收发代理模块发送主动断链消息304给已经建链的对端微波网元，告知断开临跳通道，并将与对端微波网元之间的临跳通道的状态置为断开状态；The impending jump information management module sends an active link disconnection message 304 to the peer microwave network element that has already established a link through the sending and receiving agent module, notifying to disconnect the impending jump channel, and setting the status of the impending jumping channel with the peer microwave network element to is disconnected;
对端微波网元的收发代理模块收到主动断链消息304后，向本地微波网元的收发代理模块回复断链应答消息305，并将主动断链消息304转发给临跳信息管理模块，对端微波网元的临跳信息管理模块收到主动断链消息304后将相应的临跳通道的状态置为断开状态。After receiving the active link disconnection message 304, the sending and receiving agent module of the peer microwave network element replies with a link breaking response message 305 to the sending and receiving agent module of the local microwave network element, and forwards the active link breaking message 304 to the impending jump information management module. After receiving the active link disconnection message 304, the impending information management module of the end microwave network element sets the state of the corresponding impending channel to disconnected.
其中，若本地微波网元连续发送预设次数的主动断链消息304均未收到对端微波网元回复的断链应答消息305，则也认为临跳通道链路断开，由本地临跳信息管理模块将与对端微波网元之间的临跳通道的状态置为断开状态。Wherein, if the local microwave network element continuously sends the preset number of active link disconnection messages 304 and does not receive the link disconnection response message 305 returned by the peer microwave network element, then it is also considered that the link of the impending channel is disconnected, and the local impending link The information management module sets the state of the impending channel with the peer microwave network element as disconnected.
本发明的微波网元间的信息传输方法，微波网元间通信连接的建立不使用基于IP的网络通信协议，简化了通信流程；在建立连接的过程中微波网元无需知道对端微波网元的任何信息也可建立通信连接并交换信息，微波网元之间信息交换的格式可以使用采用任意形式，既可以交换网管数据也可以交换其它业务相关的数据。In the information transmission method between microwave network elements of the present invention, the establishment of communication connections between microwave network elements does not use an IP-based network communication protocol, which simplifies the communication process; in the process of establishing a connection, microwave network elements do not need to know the peer microwave network element Any information can also establish a communication connection and exchange information. The format of information exchange between microwave network elements can be used in any form, which can exchange network management data or other business-related data.

本发明实施例中，模块可以用软件实现，以便由各种类型的处理器执行。举例来说，一个标识的可执行代码模块可以包括计算机指令的一个或多个物理或者逻辑块，举例来说，其可以被构建为对象、过程或函数。尽管如此，所标识模块的可执行代码无需物理地位于一起，而是可以包括存储在不同位里上的不同的指令，当这些指令逻辑上结合在一起时，其构成模块并且实现该模块的规定目的。In the embodiments of the present invention, the modules may be implemented by software so as to be executed by various types of processors. An identified module of executable code may, by way of example, comprise one or more physical or logical blocks of computer instructions which may, for example, be structured as an object, procedure, or function. Notwithstanding, the executable code of an identified module need not be physically located together, but may include distinct instructions stored in different bits which, when logically combined, constitute the module and implement the specified Purpose.
实际上，可执行代码模块可以是单条指令或者是许多条指令，并且甚至可以分布在多个不同的代码段上，分布在不同程序当中，以及跨越多个存储器设备分布。同样地，操作数据可以在模块内被识别，并且可以依照任何适当的形式实现并且被组织在任何适当类型的数据结构内。所述操作数据可以作为单个数据集被收集，或者可以分布在不同位置上(包括在不同存储设备上)，并且至少部分地可以仅作为电子信号存在于系统或网络上。Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs and across multiple memory devices. Likewise, operational data may be identified within modules, and may be implemented in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed in different locations (including on different storage devices), and may exist, at least in part, only as electronic signals on a system or network.
