本发明涉及通信技术领域，特别涉及一种网元设备自动配置的方法、装置及系统。The present invention relates to the field of communication technology, in particular to a method, device and system for automatic configuration of network element equipment.
背景技术Background technique
网元设备应用层配置的特点是参数多，通常少则几百，多则几千。以移动核心网网元业务GPRS支持节点(SGSN，Serving GPRS Support Node，其中GPRS指通用分组无线业务(General Packet Radio Service))为例，它需要的应用层配置参数包括硬件系统、单板、时钟、端口、备份关系、软件系统、接口协议、业务特性、接口/业务IP地址、网关/路由、POOL配置、维护配置等。应用层配置不仅参数多，而且参数间的关联性强，参数类型差异大，且配置取值不仅受网络当前状态影响，还受周边网元配置的影响。The configuration of the application layer of network element equipment is characterized by many parameters, usually ranging from a few hundred to several thousand. Taking the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) of the mobile core network network element service as an example, the application layer configuration parameters required by it include hardware system, single board, clock , port, backup relationship, software system, interface protocol, service feature, interface/service IP address, gateway/routing, POOL configuration, maintenance configuration, etc. The application layer configuration not only has many parameters, but also has a strong correlation between the parameters, and the parameter types are greatly different, and the configuration value is not only affected by the current state of the network, but also by the configuration of surrounding network elements.
在通信网络中，网元的入网配置和运行中的重配置，绝大多数是由人工通过维护台控制完成的。随着网络结构及网元功能的复杂化，尤其在核心网采用池(POOL)结构的情况下，对网元配置的动态性和实时性要求越来越高，迫切需要减少配置过程中的人工干预，实现网元及网络自动配置功能。In a communication network, most of the network element configuration and reconfiguration during operation are done manually through the maintenance console. With the complexity of the network structure and network element functions, especially when the core network adopts the pool (POOL) structure, the dynamic and real-time requirements for network element configuration are getting higher and higher, and it is urgent to reduce the manual configuration process. Intervention to realize the automatic configuration function of network elements and networks.
现有存在一种自动配置的方法，该方法包括步骤：A、局域网的第一设备向互联网的自动配置装置(ACS)上报其标识；B、ACS将所述标识设置到动态域名解析服务器(DDNS)中，局域网的DDNS服务器获得第一设备的IP地址；且所述步骤B还包括：ACS将所述标识设置到要访问第一设备的第二设备中，所述第二设备保存所述标识，以便第二设备根据所述标识通过DDNS服务器解析出第一设备的IP地址，并访问第一设备。There is an existing automatic configuration method, which includes the steps: A, the first device of the local area network reports its identification to the automatic configuration device (ACS) of the Internet; B, the ACS sets the identification to the dynamic domain name resolution server (DDNS) ), the DDNS server of the local area network obtains the IP address of the first device; and the step B also includes: the ACS sets the identification in the second device to access the first device, and the second device saves the identification , so that the second device resolves the IP address of the first device through the DDNS server according to the identifier, and accesses the first device.
发明人在对现有技术研究中发现，上述方法至少存在以下问题：上述方法的自动配置只针对IP地址一个参数，解决的是传输层配置问题，目的只是使设备在传输层上连入网络，即配置完成后只达到了连接网络的目的，对于应用层仍需人工手工配置，也就是说，不能解决具有几百甚至几千个参数的应用层采用手工配置工作量大且繁杂的问题。In the research of the prior art, the inventor found that the above-mentioned method has at least the following problems: the automatic configuration of the above-mentioned method only targets one parameter of the IP address, and solves the configuration problem of the transport layer. The purpose is only to connect the device to the network on the transport layer. That is, after the configuration is completed, only the purpose of connecting to the network is achieved, and the application layer still needs to be manually configured. That is to say, it cannot solve the problem of heavy and complicated manual configuration of the application layer with hundreds or even thousands of parameters.
现有还存在一种基站自动配置的方法，该方法包括：通过将系统中的基站、路由器和基站配置信息所在系统构成一个组播域，基站获取基站配置信息所在系统的IP地址，并通过获取的IP地址向基站配置信息所在系统发送携带有基站标识的IP登记包；基站配置信息所在系统根据接收到的IP登记包中携带的基站标识查询并获取该基站的配置信息，并通过组播IP包发送给基站；基站从接收到的组播IP包中获取自身的配置信息，实现了基站的自动配置。There is also a method for automatic base station configuration, which includes: by forming a multicast domain with base stations, routers, and the system where the base station configuration information is located, the base station obtains the IP address of the system where the base station configuration information is located, and obtains the IP address of the system where the base station configuration information is located. The IP address of the base station configuration information sends an IP registration packet carrying the base station identifier to the system where the base station configuration information is located; the system where the base station configuration information resides queries and obtains the configuration information of the base station according to the base station identifier carried in the received IP registration packet, and broadcasts the information through the multicast IP The packet is sent to the base station; the base station obtains its own configuration information from the received multicast IP packet, realizing the automatic configuration of the base station.
发明人在上述现有技术的研究中发现，上述方法其至少存在以下问题：上述方法仅局限于基站，且每个基站被当作一个单独设备来配置，配置结果的来源也是预先设置，而不是动态产生的。当网络形式更复杂，网元间的关联性更大，尤其是存在POOL组网的情况下，不仅要对网元本身进行配置，还要考虑邻居配置和邻域网元配置。该方法同样不能解决具有几百甚至几千个参数的应用层采用手工配置工作量大且繁杂的问题。The inventor found in the research of the above-mentioned prior art that the above-mentioned method has at least the following problems: the above-mentioned method is limited to the base station, and each base station is configured as a separate device, and the source of the configuration result is also preset, not generated dynamically. When the network form is more complex and the correlation between NEs is greater, especially when there is a POOL network, it is necessary not only to configure the NE itself, but also to consider the configuration of neighbors and neighboring NEs. This method also cannot solve the problem of heavy and complicated manual configuration of the application layer with hundreds or even thousands of parameters.

Authentication. After the authentication is passed, the network element management node negotiates with the new MME to establish a secure transmission channel. The basic security shared key may specifically be a security key or a certificate.
如果需要，认证通过后，地址分配中心还可以为新MME重新分配动态IP地址(如果需要，则地址分配中心为新MME再重新分配动态IP地址，不需要则不用分配)。If necessary, after passing the authentication, the address allocation center can also re-allocate the dynamic IP address for the new MME (if necessary, the address allocation center can re-allocate the dynamic IP address for the new MME, if not necessary, do not need to allocate).
上述安全传输通道跨越网元所在的业务网络与管理节点所在的维护网之间可以存在的公共网络(网元所在的业务网络与管理节点所在的维护网之间可以存在公共网络，也可以不存在公共网络)。网元管理节点作为维护网的入口，可以把自动配置装置、软件服务器等功能实体屏蔽在安全的维护网内部，并为这些功能实体与网元的交互提供安全传输保障。The above secure transmission channel spans the public network that may exist between the service network where the network element is located and the maintenance network where the management node is located (there may or may not be a public network between the service network where the network element is located and the maintenance network where the management node is located. public network). As the entrance of the maintenance network, the network element management node can shield functional entities such as automatic configuration devices and software servers in the secure maintenance network, and provide secure transmission guarantee for the interaction between these functional entities and network elements.
步骤1.5网元管理节点向新MME发送设备接入响应，其中包含软件服务器地址和自动配置装置的地址，这样新MME就可以直接与这些服务器通信了。Step 1.5 The network element management node sends a device access response to the new MME, which contains the address of the software server and the address of the automatic configuration device, so that the new MME can directly communicate with these servers.
步骤1.6新MME根据软件服务器的IP地址与软件服务器建立连接，下载与自身匹配的软件。软件与硬件相关，同时会影响到配置参数的取值。Step 1.6 The new MME establishes a connection with the software server according to the IP address of the software server, and downloads the software matching itself. Software is related to hardware, and will also affect the value of configuration parameters.
步骤1.7新MME在本地加载新的软件，为自动配置作好准备。Step 1.7 The new MME loads new software locally to prepare for automatic configuration.
图5是基于实施例一的图2所述方法实施例中步骤2的具体流程图。参见图3和图5，收集用于所述新网元配置的决策信息，根据所述决策信息生成所述新网元的完整应用层配置信息的步骤如下：Fig. 5 is a specific flow chart of step 2 in the method embodiment shown in Fig. 2 based on the first embodiment. Referring to Fig. 3 and Fig. 5, the steps of collecting the decision information for the configuration of the new network element, and generating the complete application layer configuration information of the new network element according to the decision information are as follows:
步骤2.1新MME向自动配置装置发送自动配置请求，其中包含自己在本地检测到的用于应用层配置的基本参数，如硬件版本、单板列表、端口时钟信息、软件版本，还可以包括生产日期、系统运行模式等，这些信息将用来决定新MME的其它配置的取值。Step 2.1 The new MME sends an automatic configuration request to the automatic configuration device, which contains the basic parameters detected locally by itself for application layer configuration, such as hardware version, single board list, port clock information, software version, and may also include production date , system operation mode, etc. These information will be used to determine the values of other configurations of the new MME.
步骤2.2如果自动配置装置需要新MME提供更多用于配置决策的信息，尤其是需要现场测量的信息，它将向新MME发送测量参数请求。新MME也可以根据一些预置的要求提前进行测量，并把结果随同配置请求一起发给自动配置装置。Step 2.2 If the automatic configuration device needs more information from the new MME for configuration decisions, especially information requiring on-site measurements, it will send a measurement parameter request to the new MME. The new MME can also perform measurements in advance according to some preset requirements, and send the results together with the configuration request to the automatic configuration device.
步骤2.3新MME收到测量参数请求后，按指定的内容完成现场测量，然后将测量结果通过测量参数响应消息发给自动配置装置，该信息被存储于自动配置装置内部，用于后续的自动配置决策。Step 2.3 After the new MME receives the measurement parameter request, it completes the on-site measurement according to the specified content, and then sends the measurement result to the automatic configuration device through the measurement parameter response message, and the information is stored in the automatic configuration device for subsequent automatic configuration decision making.
步骤2.4如果自动配置装置需要借鉴网络规划信息，而这些信息又在自身找不到，它将向网络规划装置请求与新MME相关的规划参数，如接口地址、业务地址、路由、网关、Pool等规划参数。这些参数一般由网络运营商直接设定，可能被应用于包括多个子网的整个网络。网络规划装置本身可能是一个独立装置，也可能属于网络高层管理节点的一部分。Step 2.4 If the automatic configuration device needs to learn from the network planning information, and this information cannot be found by itself, it will request the planning parameters related to the new MME from the network planning device, such as interface address, service address, route, gateway, Pool, etc. planning parameters. These parameters are generally set directly by the network operator, and may be applied to the entire network including multiple subnets. The network planning device itself may be an independent device, or may belong to a part of the network high-level management node.
步骤2.5网络规划装置向自动配置装置返回它需要的规划信息。该信息被存储于自动配置装置内部，用于后续的自动配置决策。Step 2.5 The network planning device returns the planning information it needs to the automatic configuration device. This information is stored inside the auto-configuration device for subsequent auto-configuration decisions.
步骤2.6如果自动配置装置还需要借鉴相邻网域的配置信息，或者需要做一些配置协商，它将通过事先建立好的通道向邻域自动配置装置请求。Step 2.6 If the automatic configuration device still needs to learn from the configuration information of the adjacent network domain, or needs to do some configuration negotiation, it will request to the neighboring area automatic configuration device through the pre-established channel.
步骤2.7邻域的自动配置装置返回相关的配置信息和协商结果。一般来说，需要进行邻域协商的配置包括传输层带宽、服务质量(QOS)参数、QOS映射算法等。邻域配置协商的目的在于保持子网络之间的配置一致性。In step 2.7, the automatic configuration device in the neighborhood returns relevant configuration information and negotiation results. Generally, the configurations that need to be negotiated include transport layer bandwidth, quality of service (QOS) parameters, QOS mapping algorithms, and the like. The purpose of neighborhood configuration negotiation is to maintain configuration consistency among subnetworks.
至此，自动配置装置已收集到了用于应用层配置的基本参数、现场测量信息、网络规划信息、相邻网域的配置信息。在上述实施例中，网络规划信息和相邻网域的配置信息是分别从网络规划装置和邻域自动配置装置获取的，在实际应用中，如果自动配置装置本地已保存了所需要的网络规划信息和相邻网域的配置信息，也可以直接从本地获取，而不再与网络规划装置和邻域自动配置装置进行联系。So far, the automatic configuration device has collected basic parameters for application layer configuration, on-site measurement information, network planning information, and configuration information of adjacent network domains. In the above embodiments, the network planning information and the configuration information of adjacent network domains are respectively obtained from the network planning device and the neighborhood automatic configuration device. In practical applications, if the automatic configuration device has saved the required network planning locally Information and configuration information of adjacent network domains can also be obtained directly from the local area without contacting the network planning device and the neighborhood automatic configuration device.
步骤2.8，除了上述从外部收集到的用于所述新MME配置的决策信息之外，自动配置装置还在本地保存本网域内所有已存在网元(如图3中的MME1、MME2和信令网关(SGW))的完整应用层配置信息即新MME所在网域内的所有已存在网元的完整应用层配置信息，这些也是自动配置装置用于决定新MME配置取值的重要参考依据。待所有用于所述新MME配置的决策信息收集完毕后，自动配置装置按照预先设定的规则为新MME生成运行所需的完整应用层配置信息。该预先设定的规则可以是运营商和/或用户提前设置的。Step 2.8, in addition to the above-mentioned decision-making information collected from the outside for the configuration of the new MME, the automatic configuration device also locally saves all existing network elements in the network domain (MME1, MME2 and signaling The complete application layer configuration information of the gateway (SGW) is the complete application layer configuration information of all existing network elements in the network domain where the new MME is located, which is also an important reference basis for the automatic configuration device to determine the configuration value of the new MME. After all the decision information for the configuration of the new MME is collected, the automatic configuration device generates the complete application layer configuration information required for the new MME to run according to the preset rules. The preset rule may be set in advance by the operator and/or the user.
图6是基于实施例一的图2所述方法实施例中步骤3的具体流程图。参见图3和图6，经所述安全传输通道将所述完整的应用层配置信息下发给所述新网元的步骤如下：Fig. 6 is a specific flowchart of step 3 in the method embodiment shown in Fig. 2 based on the first embodiment. Referring to Fig. 3 and Fig. 6, the steps of sending the complete application layer configuration information to the new network element via the secure transmission channel are as follows:
步骤3.1，自动配置装置将新MME的完整应用层配置信息经前述建立的安全传输通道通过自动配置响应消息下发给新MME；并且，自动配置装置还把对新MME的配置加入自己的本地存储中，用于后续修改或其它网元加入时的参考。新MME接收到完整配置后，完成本地配置。Step 3.1, the automatic configuration device sends the complete application layer configuration information of the new MME to the new MME through the aforementioned secure transmission channel through the automatic configuration response message; and the automatic configuration device also adds the configuration of the new MME to its local storage In , it is used for subsequent modification or reference when other network elements are added. After receiving the complete configuration, the new MME completes the local configuration.
将所述完整的应用层配置信息下发给新MME之后还可以包括：After sending the complete application layer configuration information to the new MME, it may also include:
步骤3.2，新MME向自动配置装置返回配置结果确认消息；为了避免配置数据在下发和应用过程中出现异常，引起网元间关键配置冲突，新MME将已应用的配置参数中的若干关键项取值作为校验信息发回给自动配置装置，自动配置装置将在配置下发全部完成之后进行配置结果校验。In step 3.2, the new MME returns a configuration result confirmation message to the automatic configuration device; in order to avoid abnormalities in the distribution and application of configuration data, which may cause key configuration conflicts between network elements, the new MME removes some key items from the applied configuration parameters. The value is sent back to the automatic configuration device as verification information, and the automatic configuration device will verify the configuration result after all configurations are delivered.
步骤3.3，如果自动配置装置判断出由于新MME的加入会影响本网域内的其它网元的运行，例如对MME1和MME2而言需要增加POOL成员信息，对于SGW需要更新与POOL之间连接关系等等，自动配置装置将修改本地存储的MME1、MME2和SGW的配置，并将所述修改后的配置携带在配置更新消息中，发给由于新MME的加入而影响的本网域内的其它网元，如MME1、MME2和SGW；Step 3.3, if the automatic configuration device judges that the addition of a new MME will affect the operation of other network elements in the network domain, for example, for MME1 and MME2, POOL member information needs to be added, and for SGW, the connection relationship with POOL needs to be updated, etc. etc., the automatic configuration device will modify the locally stored configurations of MME1, MME2, and SGW, and carry the modified configuration in the configuration update message, and send it to other network elements in the network domain affected by the addition of the new MME , such as MME1, MME2 and SGW;
步骤3.4，自动配置装置向MME1、MME2和SGW分别发送配置更新消息；Step 3.4, the automatic configuration device sends configuration update messages to MME1, MME2 and SGW respectively;
例如，自动配置装置向MME1和MME2发送包含增加POOL成员信息的更新消息，向SGW发送包含更新与POOL之间连接关系的更新消息。也就是说，自动配置装置需要更新本网域内由于新MME的加入而受影响的已存在网元的配置信息，将更新后配置信息下发给由于新网元的加入而受影响的已存在网元。For example, the automatic configuration device sends an update message including adding POOL member information to MME1 and MME2, and sends an update message including updating the connection relationship with the POOL to the SGW. That is to say, the automatic configuration device needs to update the configuration information of the existing network elements affected by the addition of the new MME in the local network domain, and send the updated configuration information to the existing network elements affected by the addition of the new network elements. Yuan.
步骤3.5，MME1、MME2和SGW向自动配置装置返回配置结果确认，其中也包含配置校验所需的校验信息；Step 3.5, MME1, MME2 and SGW return configuration result confirmation to the automatic configuration device, which also includes verification information required for configuration verification;
步骤3.6，自动配置装置对本网域内的网元配置进行校验，防止在设备逻辑标识、地址、覆盖区域、容量对接、接口特性、业务特性等方面出现冲突；如果校验结果出现冲突，自动配置装置将对配置信息进行修改并重新下发给有问题的网元。这里的配置信息包括新MME的完整应用层配置信息，或由于新网元加入而受影响的已存在网元的更新后配置信息。In step 3.6, the automatic configuration device verifies the configuration of the network elements in the network domain to prevent conflicts in terms of equipment logical identifiers, addresses, coverage areas, capacity connection, interface characteristics, and service characteristics; if there is a conflict in the verification results, the automatic configuration The device will modify the configuration information and re-send it to the network element with the problem. The configuration information here includes the complete application layer configuration information of the new MME, or the updated configuration information of the existing network elements affected by the addition of new network elements.
在网络运行过程中，自动配置装置也可以要求网元定期上报配置校验信息，以防止因运行造成的配置冲突。During network operation, the automatic configuration device may also require network elements to report configuration verification information periodically, so as to prevent configuration conflicts caused by operation.
步骤3.7，如果自动配置装置判断由于新MME的加入会影响相邻网域的网元的运行，例如新MME作为MME POOL中新的一员，需要通知所有连接到MME POOL的演进型基站(eNodeB)与它建立S1接口连接。核心网的自动配置装置通过预先建立的通道将新MME的配置信息发送给邻域的自动接入装置，本例中该邻域的自动接入装置即为接入网的自动配置装置。邻域之间的配置同步一般只需要交换双方互相关联的那部分配置信息(例如用于eNodeB接入的新MME的IP地址)，即自动配置装置需要将新MME的与邻域交互相关联的配置信息发送给邻域自动配置装置。Step 3.7, if the automatic configuration device judges that the addition of the new MME will affect the operation of network elements in adjacent network domains, for example, the new MME is a new member of the MME POOL, and all evolved base stations (eNodeBs) connected to the MME POOL need to be notified ) to establish an S1 interface connection with it. The automatic configuration device of the core network sends the configuration information of the new MME to the automatic access device of the neighboring area through the pre-established channel. In this example, the automatic access device of the neighboring area is the automatic configuration device of the access network. The configuration synchronization between neighbors generally only needs to exchange the part of the configuration information related to each other (for example, the IP address of the new MME used for eNodeB access), that is, the automatic configuration device needs to associate the interaction between the new MME and the neighbors The configuration information is sent to the neighborhood automatic configuration device.
步骤3.8接入网的自动配置装置将收到的新MME配置信息保存在本地，并发送给所有连接到该MME POOL的eNodeB，也即附图中其它网元。对于后续加入到接入网的新eNodeB，在接入网的自动装置为它所生成的完整配置中，就已经包括了前面的这个新MME地址。Step 3.8 The automatic configuration device of the access network saves the received new MME configuration information locally, and sends it to all eNodeBs connected to the MME POOL, that is, other network elements in the figure. For a new eNodeB subsequently added to the access network, the previous new MME address has already been included in the complete configuration generated for it by the automatic device of the access network.
图7是基于实施例一的图2所述方法实施例中步骤4的具体流程图，参见图3和图7，新网元所在网域内的自动配置装置监控本域网的网络变化状态，更新由于网络状态变化而受影响的网元的配置信息，并下发给所述网元的步骤如下：Fig. 7 is a specific flowchart of step 4 in the method embodiment described in Fig. 2 based on Embodiment 1. Referring to Fig. 3 and Fig. 7, the automatic configuration device in the network domain where the new network element is located monitors the network change status of the local area network and updates The steps of distributing the configuration information of the network elements affected due to network status changes to the network elements are as follows:
步骤4.1～4.7，在网络运行过程中，自动配置装置监控网络变化状态，更新由于网络状态变化而受影响的网元的配置信息，并下发给由于网络状态变化而受影响的网元。In steps 4.1 to 4.7, during network operation, the automatic configuration device monitors network change status, updates the configuration information of network elements affected by network state changes, and distributes the configuration information to network elements affected by network state changes.

自动配置装置所在网域中的接收到配置信息的网元向自动配置装置返回配置结果确认，其中也包含配置校验所需的校验信息。自动配置装置对本网域内的网元配置进行校验，防止在设备逻辑标识、地址、覆盖区域、容量对接、接口特性、业务特性等方面出现冲突。如果校验结果出现冲突，自动配置装置将对配置信息进行修改并重新下发给出现冲突的网元。The network element that receives the configuration information in the network domain where the automatic configuration device is located returns a configuration result confirmation to the automatic configuration device, which also includes verification information required for configuration verification. The automatic configuration device verifies the configuration of the network elements in the network domain to prevent conflicts in terms of equipment logical identification, address, coverage area, capacity docking, interface characteristics, and service characteristics. If there is a conflict in the verification result, the automatic configuration device will modify the configuration information and send it to the conflicting network element again.
上述由于网络状态变化而受影响的网元可能是新MME所在网域内的自动配置装置所管辖的网元，也可能是新网元所在网域的邻域中的网元。The aforementioned network elements affected by the change of network status may be network elements under the jurisdiction of the automatic configuration device in the network domain where the new MME is located, or may be network elements in the neighborhood of the network domain where the new network element is located.
本发明实施例通过自动采集新入网网元的基本配置参数，结合网络规划和已有网元的配置参数，自动为新入网网元进行应用层自动配置。The embodiment of the present invention automatically collects the basic configuration parameters of the new network elements, and combines the network planning and the configuration parameters of the existing network elements to automatically configure the application layer for the new network elements.

如果校验结果出现冲突，则自动配置装置对配置信息进行修改并重新下发。If there is a conflict in the verification result, the automatic configuration device modifies the configuration information and re-delivers it.
同样的，自动配置装置将所述网域内已存在网元的与邻域交互相关联的配置信息发送给邻域自动配置装置，由邻域自动配置装置进行相应配置。Similarly, the automatic configuration device sends the configuration information associated with the neighborhood interaction of the existing network elements in the network domain to the neighborhood automatic configuration device, and the neighborhood automatic configuration device performs corresponding configuration.
