Translated fromChinese技术领域technical field
本发明涉及通信技术领域，尤其涉及一种终端分布信息获取方法、数据获取装置以及通信系统。The present invention relates to the technical field of communication, and in particular to a terminal distribution information acquisition method, a data acquisition device and a communication system.
背景技术Background technique
深度数据包检测(Deep Packet Inspection，以下简称：DPI)技术不仅能够如同普通报文检测一样，分析出IP数据包中的源地址、目的地址、源端口、目的端口以及协议类型，而且还增加了应用层分析，能够高效的识别出网络上的各种应用及其内容，Deep Packet Inspection (hereinafter referred to as: DPI) technology can not only analyze the source address, destination address, source port, destination port and protocol type in the IP data packet like ordinary packet inspection, but also adds Application layer analysis can efficiently identify various applications and their content on the network,
普通报文检测是通过端口号来识别应用类型的，如检测到端口号为80时，则认为该应用代表着普通上网应用。而当前网络上的一些非法应用会采用隐藏或假冒端口号的方式躲避检测和监管，造成仿冒合法报文的数据流侵蚀着网络。此时普通报文检测方法就无能为力了。DPI技术就是通过对应用流中的数据报文内容进行探测，从而确定数据报文的真正应用。Ordinary message detection identifies the application type through the port number. If the detected port number is 80, it is considered that the application represents a common Internet application. However, some illegal applications on the current network hide or forge port numbers to evade detection and supervision, causing the data flow of counterfeit legal packets to erode the network. At this time, the ordinary packet detection method is powerless. The DPI technology detects the content of the data message in the application flow to determine the real application of the data message.

Distribution information for statistics. In the prior art, the statistics of the above-mentioned information of the squadron is carried out by the communication operator from the network management system, the business operation support system (Business & Operation Support System, hereinafter referred to as: BOSS) to export the user bill, or the way of manual statistical analysis after the consumption record Obtain. The method of collecting statistics on the distribution information of terminals such as mobile phones in the prior art generally has the defect of low statistical efficiency, and at the same time, the precision of the statistical results is also low.

本发明上述实施例中，由于IP数据传输的特性，一个按照协议生成完整的数据报文可能被分为多个数据包传输，即上述预解析的数据报文可能是完整数据报文，或者是非完整数据报文。其中对于完整的数据报文，可以通过深度数据包检测装置一次解析获得协议解析数据，而对数据报文是非完整的数据报文的情况，上述步骤101中可以是至少两次向DPI装置发送携带预解析的非完整数据报文的请求消息，而步骤102可以是接收DPI装置返回的根据至少两个非完整性数据报文进行解析获取的协议解析数据。而上述解析非完整数据报文的情况，具体的可以是在首次向DPI装置发送预解析的数据报文后，DPI装置检测获得部分协议解析数据，将其封装到上下文信息中，DPI装置返回携带上述上下文信息以及指示需要再次进行数据检测信息的响应响应消息，数据获取装置再次发送携带非完整数据报文的请求消息，同时还携带上述的上下文信息，以由DPI装置根据新获得的非完整数据报文进一步进行协议解析，并将前后两次获得的协议解析数据进行合并，直到能够获得完整的协议解析数据为止，否则将持续执行上述的流程。In the above embodiments of the present invention, due to the characteristics of IP data transmission, a complete data message generated according to the protocol may be divided into multiple data packets for transmission, that is, the above-mentioned pre-analyzed data message may be a complete data message, or a non- complete datagram. Wherein for the complete data message, the protocol analysis data can be obtained by analyzing the deep data packet detection device once, and the data message is an incomplete data message, in the above-mentioned step 101, it can be sent to the DPI device at least twice to carry The request message of the pre-parsed incomplete data message, and step 102 may be to receive the protocol analysis data returned by the DPI device and obtained by parsing and obtaining at least two incomplete data messages. In the case of parsing the incomplete data message above, specifically, after the pre-analyzed data message is sent to the DPI device for the first time, the DPI device detects and obtains part of the protocol analysis data, encapsulates it into the context information, and the DPI device returns the carried The above context information and the response message indicating that data detection information needs to be performed again, the data acquisition device sends the request message carrying the incomplete data message again, and also carries the above context information at the same time, so that the DPI device can use the newly obtained incomplete data The message is further subjected to protocol analysis, and the protocol analysis data obtained twice before and after are merged until the complete protocol analysis data can be obtained, otherwise the above process will continue to be executed.
另外，本发明上述实施例中，对于终端的类型标识可以是国际移动设备标识码中的设备型号核准号码，而上述步骤102中数据获取装置在接收到DPI装置返回的携带协议解析数据的响应消息之后，数据获取装置进一步的执行下述步骤：In addition, in the above-mentioned embodiments of the present invention, the type identification of the terminal may be the equipment model approval number in the International Mobile Equipment Identity Code, and in the above-mentioned step 102, the data acquisition device receives the response message carrying the protocol analysis data returned by the DPI device Afterwards, the data acquisition device further performs the following steps:

And the protocol analysis data carried in the notification message sent to the data aggregation device includes the mobile terminal model sending the data message, the protocol type of the data message and the service flow value corresponding to the protocol type.
图2为本发明一具体实施例的流程示意图，如上所述的，发送给DPI装置的数据报文可以是完整数据报文，或者是非完整数据报文，本实施例中是针对完整数据报文的情况，如图2所示，包括如下步骤：Fig. 2 is a schematic flow chart of a specific embodiment of the present invention, as mentioned above, the data message sent to the DPI device can be a complete data message, or an incomplete data message, in this embodiment it is aimed at a complete data message The situation, as shown in Figure 2, includes the following steps:
步骤201、移动终端(Mobile Station，以下简称：MS)向服务器发送IP数据包(例如IP Packet1和IP Packet2)，上述的IP数据包经过GGSN，且各个IP数据包在GGSN上进行流匹配和重组，对于一个业务流上的IP数据包进行排序，并过滤重复的数据报文，得到TCP数据包(TCP Packet1和TCPPacket2)，进一步的，该GGSN上还设置有上述的数据获取装置，该数据获取装置会根据预先配置的规则，选择性的向DPI装置发送请求消息，该请求消息中携带预解析的数据报文(TCP数据包)，请求DPI装置进行7层协议解析，具体的本实施例中，可以是GGSN每接收到两个IP数据包，则向DPI装置发送一次请求消息，另外还可以是设定一时间段，例如每分钟发送一次请求消息；
步骤202、DPI装置(DPI Parser)对接收到的TCP数据包进行协议解析，解析前会先识别出7层协议类型，并根据协议类型确定需要解析得到的协议解析数据，上述的协议解析数据可以包括如下的信息中的一项或多项，例如国际移动用户标识码(International Mobile Subscriber IdentificationIMSI)、国际移动设备标识码(International Mobile EquipmentIdentification，以下简称：IMEI)、协议大类(Protocol Category，例如P2P、VOIP等)、协议类型(Protocol，例如BT、eDonkey)、范围的URL名称、业务流量值(可以包括上行业务流量和下行业务流量)等信息，而上述IMET中的TAC标识是与移动终端型号一一对应的，上行业务流量可以具体是针对特定类型终端，在特定协议类上的上行业务流量，而下行业务流量也可以具体是针对特定类型终端，在特定协议类上的下行业务流量。
具体的，如图3所示，DPI装置可以包括解析规则库、预处理模块、解析模块、后处理模块、中间状态存储模块和五元组管理模块，上述的解析规则库中存储有解析规则，具体的该解析规则可以是依据不同协议类型的解析策略，可以保证对不同协议类型的TCP数据包进行解析。预处理模块在接收到封装有一个或多个IP数据包的TCP数据包后，同时从解析协议规则库中获取对应的解析规则，将其发送给解析模块进行解析，获得解析结果，由后处理模块将解析结果返回给数据获取装置，并可以将解析得到的状态信息存储到DPI装置的中间状态存储模块中，再次对IP数据包进行解析时，由预处理模块获取并发送给解析模块解析时参考，另外将上述的状态信息作为上下文信息携带在响应消息中返回给数据获取装置，以由数据获取装置在下一次针对同一业务流进行解析时，将其携带在请求消息中发送给DPI装置，而上述五元组管理模块负责五元组信息的创建、老化、更新和查询。Specifically, as shown in Figure 3, the DPI device may include a parsing rule base, a preprocessing module, a parsing module, a postprocessing module, an intermediate state storage module, and a quintuple management module, and the parsing rules are stored in the above parsing rule base, Specifically, the parsing rule may be a parsing policy based on different protocol types, which can ensure parsing of TCP data packets of different protocol types. After the preprocessing module receives the TCP data packet encapsulated with one or more IP data packets, it simultaneously obtains the corresponding parsing rules from the parsing protocol rule base, sends them to the parsing module for parsing, and obtains parsing results, which are then processed The module returns the analysis results to the data acquisition device, and can store the status information obtained by the analysis in the intermediate state storage module of the DPI device. When the IP data packet is analyzed again, it will be acquired by the preprocessing module and sent to the analysis module for analysis. For reference, in addition, carry the above-mentioned state information as context information in the response message and return it to the data acquisition device, so that the data acquisition device will carry it in the request message and send it to the DPI device when parsing the same service flow next time, and The above-mentioned quintuple management module is responsible for creating, aging, updating and querying quintuple information.
步骤203、GGSN将接收到的协议解析数据进行相应处理，并将处理后的协议解析数据发送给服务器(server)中的数据汇聚装置，该数据汇聚装置可以是具体的这里的处理可以包括是在上述的终端类型标识是IMET中的TAC标识，根据TAC标识与移动终端型号的对应关系，获取移动终端型号，并将其携带在通知消息中发送给服务器。另外对于上述步骤中涉及的上下文信息，可以在需要DPI装置再次对同一业务流的TCP数据包解析时发送给DPI装置，同时在业务流释放时释放内存中的相关上下文信息。
步骤204、GGSN根据解析的结果和协议的特性(采用配置的方式)来确定是否将后续的TCP数据包发送给DPI装置进行解析，具体的可以针对步骤201中涉及的配置规则执行，例如图2所示，GGSN对后需接收到的IP数据包(IP Packet3)，不发送给DPI进行解析，而是直接发送给服务器处理(server)。
上述实施例是针对TCP数据包为完整数据报文的情况的实施例，而针对IP数据包为非完整数据报文的情况，可如图4所示，包括如下的步骤：Above-mentioned embodiment is the embodiment that is the situation of complete data message for TCP data packet, and for the situation that IP data packet is incomplete data message, can as shown in Figure 4, comprise the following steps:
步骤301、与上述步骤201的步骤基本相同，区别在于由于IP分片的特性，GGSN发送给DPI装置的TCP数据包为非完整数据报文。Step 301 is basically the same as the
步骤302、DPI装置对接收到的非完整数据报文进行解析，由于是非完整数据报文，因此DPI装置无法通过一次解析获得完整的协议解析数据，DPI装置需要进行对非完整数据报文进行解析后缓存必要的信息，生成上下文信息。
步骤303、DPI装置向GGSN返回响应消息，该响应消息中携带需要继续发送TCP数据包进行解析的指示信息，同时还可以将上述的上下文信息发送给GGSN。GGSN会把之前接收到的IP数据包发送给服务器。
步骤304、GGSN在接收到后续的IP数据包(IP Packet3)后，会继续将转换得到的TCP数据包发送给DPI装置，由DPI装置进行解析，同时也会将上次解析得到的上下文信息发送给DPI装置。
步骤305、DPI装置对接收到的TCP数据包(TCP Packet3)进行解析，同时会将解析得到的信息与上述的上下文信息进行合并，如果已经获得完整的协议解析数据，则会将解析结果返回给GGSN，表明解析成功，同时也可以返回图2所示实施例中的上下文信息，以在解析同一业务流的TCP数据包时参考。
步骤306、GGSN将解析获得的完整的协议解析数据发送给服务器中的数据汇聚装置。另外本实施例中，GGSN也同样会将发送给DPI装置解析的IP数据包(IP Packet1、IP Packet2和IP Packet3)发送给服务器。In
