Description

国际移动设备标识信息 IMEI的处理方法与网络设备技术领域 International mobile device identification information IMEI processing method and network device

本发明涉及通讯技术领域，尤其涉及一种国际移动设备标识 IMEI信息的处理方法与网络设备。背景技术 The present invention relates to the field of communications technologies, and in particular, to a method and a network device for processing an IMEI information of an international mobile device. Background technique

目前，制造移动终端的厂商在每部用户终端出厂前，都会给每部移动终端分酉己国际移动设备标 i只 ( International Mobile Equipment Identity, IMEI ) , IMEI是用来区别移动终端的标志，储存在移动终端中，可用于监控被窃或无效的移动终端。制造厂商在分配 IMEI 时，应保证每部移动终端的 IMEI不同，但是，仍存在一些用户的移动终端在购买时，就已经被篡改或者部分制造厂商不按照标准分配 IMEI的情况，从而导致网络中多部移动终端的 IMEI出现重复的现象。 At present, manufacturers of mobile terminals will distribute each mobile terminal to the International Mobile Equipment Identity (IMEI) before each user terminal leaves the factory. IMEI is used to distinguish the mobile terminal's logo. In a mobile terminal, it can be used to monitor a stolen or invalid mobile terminal. When assigning IMEI, manufacturers should ensure that the IMEI of each mobile terminal is different. However, there are still some users whose mobile terminals have been tampered with at the time of purchase, or some manufacturers do not distribute IMEI according to the standard, resulting in the network. The IMEI of multiple mobile terminals is repeated.

在移动终端接入网络后，网络设备随机分配给每部移动终端一个临时标口、（^口，分组临时移动用户标 i只 ( Packet Temporary Mobile Subscriber Identity , PTMSI ) 、全球唯一临时身份 ( Globally Uuique Temporary Identity, GUTI )等），当移动终端在多个网络设备间进行相关业务时，网络设备需要通过分配的临时标识来跟踪移动终端，用 IMEI来标识移动终端。当移动终端在网络设备间切换时，虽然部分网络设备可以分配不同的临时标识来区分移动终端，但是还是存在网络设备只能通过 IMEI来跟踪移动终端，导致重复 IMEI的移动终端进行的业务是无法继续执行的。 After the mobile terminal accesses the network, the network device randomly assigns each mobile terminal a temporary standard port, (^ port, packet Temporary Mobile Subscriber Identity (PTMSI), global unique temporary identity (Globally Uuique) Temporary Identity, GUTI), etc., when the mobile terminal performs related services between multiple network devices, the network device needs to track the mobile terminal through the assigned temporary identifier, and identify the mobile terminal by using the IMEI. When the mobile terminal switches between the network devices, although some network devices can allocate different temporary identifiers to distinguish the mobile terminals, there are still network devices that can only track the mobile terminal through the IMEI, and the services performed by the mobile terminal that repeats the IMEI cannot be performed. Continue to execute.

因此，现有技术中存在以下缺点： 1 ) 当存在较多 IMEI冲突的情况时，根据现有的标准协议，整个网络中只能允许一个拥有此 IMEI的移动终端手机执行相关业务，造成用户使用被篡改或者制造厂商不按照标准分配 IMEI的移动终端时，无法执行相关业务。发明内容 Therefore, the following disadvantages exist in the prior art: 1) When there are many IMEI conflicts, according to the existing standard protocol, only one mobile terminal mobile phone having the IMEI can be allowed in the entire network. When the related service is executed, the user cannot use the mobile terminal that has been tampered with or the manufacturer does not distribute the IMEI according to the standard. Summary of the invention

为使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明具体实施例作进一步的详细描述。 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

下面以图 1为例详细说明本发明实施例提供的国际移动设备标识信息的处理方法，图 1为本发明实施例一提供的国际移动设备标识 IMEI信息的处理方法流程图，在本发明实施例中实施主体为网络设备。如图 1所示，该实施例包括以下步骤： The following is a detailed description of a method for processing international mobile device identification information according to an embodiment of the present invention. FIG. 1 is a flowchart of a method for processing an international mobile device identifier IMEI information according to Embodiment 1 of the present invention. The implementation entity is a network device. As shown in Figure 1, this embodiment includes the following steps:

步骤 110、网络设备接收由基站转发的第一用户终端发送的接入请求消息。具体地，第一用户终端向基站（eNodeB )发送接入请求信息，进而发起接入流程，基站接收到接入请求信息后，将接入请求信息向网络设备转发，网络设备接收由第一用户终端经基站转发的接入请求消息。 Step 110: The network device receives an access request message sent by the first user terminal forwarded by the base station. Specifically, the first user terminal sends the access request information to the base station (eNodeB), and then initiates an access procedure. After receiving the access request information, the base station forwards the access request information to the network device, and the network device receives the first user. An access request message forwarded by the terminal via the base station.

在本发明实施例中，所述第一用户终端为手机，所述网络设备指通信系统中的服务设备，如 SGSN、 MME、 MSC等。 In the embodiment of the present invention, the first user terminal is a mobile phone, and the network device refers to a service device in a communication system, such as an SGSN, an MME, an MSC, and the like.

步骤 120、当所述接入请求消息携带所述第一用户终端的原始 IMEI信息时，识别所述原始 IMEI 信息是否与已经处于网络中的第二用户终端使用的 IMEI信息相同。 Step 120: When the access request message carries the original IMEI information of the first user terminal, it is determined whether the original IMEI information is the same as the IMEI information used by the second user terminal that is already in the network.

具体地，网络设备在接收到接入请求消息后，对所述接入请求消息进行解析，从中提取相关的信息，当网络设备从接入请求消息中提取的信息为第一用户终端的原始 IMEI信息时，则网络设备识别原始 IMEI信息是否与已经处于网络中的第二用户终端使用的 IMEI信息相同。 Specifically, after receiving the access request message, the network device parses the access request message, and extracts related information, where the information extracted by the network device from the access request message is the original IMEI of the first user terminal. In the case of information, the network device identifies whether the original IMEI information is the same as the IMEI information used by the second user terminal already in the network.

步骤 130、如果所述原始 IMEI信息与所述已经处于网络中的第二用户终端使用的 IMEI信息相同，则根据所述原始 IMEI信息、所述第一用户终端的访问序号及所述网络设备信息构造目标 IMEI信息。 Step 130: If the original IMEI information is the same as the IMEI information used by the second user terminal that is already in the network, according to the original IMEI information, the access sequence number of the first user terminal, and the network device information. Construct target IMEI information.

具体地，在网络设备中存在一个标识数据库，在所述标识数据库中存储的为已经处于网络中的第二用户终端的 IMEI信息，可以理解的是，标识数据库中存储了多个第二用户终端的 IMEI信息。 Specifically, an identifier database exists in the network device, and the IMEI information of the second user terminal that is already in the network is stored in the identifier database. It can be understood that multiple second user terminals are stored in the identifier database. IMEI information.

识别所述原始 IMEI 信息是否与已经处于网络中的第二用户终端使用的 IMEI信息相同具体为： Identifying whether the original IMEI information is the same as the IMEI information used by the second user terminal already in the network is:

识别原始 IMEI信息是否与标识数据库存储的 IMEI信息相同，如果该原始 IMEI信息与标识数据库存储的 IMEI信息相同，则说明该原始 IMEI信息已经被第二用户终端使用，造成 IMEI 信息冲突，且第二用户终端利用该原始 IMEI信息执行相关业务，此时，网络设备根据原始 IMEI信息、第一用户终端的访问序号及网络设备信息构造目标 IMEI信息。 Determining whether the original IMEI information is the same as the IMEI information stored in the identifier database. If the original IMEI information is the same as the IMEI information stored in the identifier database, it indicates that the original IMEI information has been used by the second user terminal, causing IMEI information conflict, and the second The user terminal performs the related service by using the original IMEI information. At this time, the network device constructs the target IMEI information according to the original IMEI information, the access sequence number of the first user terminal, and the network device information.

进一步地，网络设备可以基于现有技术中 IMEI信息的结构构造目标 IMEI 信息。目前，在现有的标准协议中， IMEI信息的前 2位数字 "冊" 代表 "申报机构标识符" ，接着的 6位数 "XXXXYY" 代表 "申报机构定义的手机型号标示符" ，接着的 6位数 "ZZZZZZ" 代表 "制造厂商定义的生产顺序号" ，最后 1位数通常是 "0" , 为检验码。 Further, the network device can construct the target IMEI based on the structure of the IMEI information in the prior art. information. Currently, in the existing standard protocol, the first two digits of the IMEI information "book" represents the "declaration authority identifier", and the next six digits "XXXXYY" represent the "mobile phone model identifier defined by the reporting organization", followed by The 6-digit "ZZZZZZ" stands for "manufacturer-defined production sequence number", and the last 1 digit is usually "0", which is the check code.

对于构造的目标 IMEI信息，可以通过重新定义 "冊" 和 "ZZZZZZ" 来构造并识别。 For the constructed target IMEI information, it can be constructed and identified by redefining the "book" and "ZZZZZZ".

例如，可以将 "冊" 定义为第一用户终端的访问序号，其中，可选地， "NN" 釆用现有标准协议中未分配的序号；将 "ZZZZZZ" 定义为网络设备信息或者为访问需要信息。由于 "XXXXYY" 反映的是手机的硬件型号信息，因此，在本发明实施例中未被重新定义，上述定义方式仅为一个具体例子，在实际应用中并不限制于此。 For example, the "book" can be defined as the access serial number of the first user terminal, wherein, optionally, "NN" uses the unassigned serial number in the existing standard protocol; defines "ZZZZZZ" as network device information or for access Need information. Since "XXXXYY" reflects the hardware model information of the mobile phone, it is not redefined in the embodiment of the present invention. The above definition is only a specific example, and is not limited thereto in practical applications.

需要说明的是，构造的目标 IMEI信息应尽量保证分配结果全球唯一，且与第一用户终端的原始 IMEI信息不冲突。 It should be noted that the constructed target IMEI information should try to ensure that the allocation result is globally unique and does not conflict with the original IMEI information of the first user terminal.

进一步地，如图 2所示，图 2为本发明实施例提供的网络设备构造目标 IMEI示意图；在图 2中，用户终端 A和用户终端 B分别通过位置 A和位置 B 的基站向网络设备发送接入请求消息，在每个接入请求消息中携带各自的原始 IMEI信息，网络设备收到经不同位置的基站发送的接入请求消息，经解析和提取接入请求信息携带的原始 IMEI信息后，识别出用户终端 A和用户终端 B的原始 IMEI信息与标识数据库中存储的 IMEI信息相同，则网络设备根据用户终端 A的原始 IMEI信息（IMEI _A )、用户终端 A的访问序号（在图 1中用户终端 A的访问序号为 1 )及网络设备信息构造用户终端 A的目标 IMEI信息，则用户终端 A的目标 IMEI信息为： IMEI _A_ 1 ; 同理，网络设备构造用户终端 B的目标 IMEI信息为： IMEI _A_2。 Further, as shown in FIG. 2, FIG. 2 is a schematic diagram of a network device configuration target IMEI according to an embodiment of the present invention; in FIG. 2, user terminal A and user terminal B respectively send a base station of location A and location B to a network device. The access request message carries the original IMEI information in each access request message, and the network device receives the access request message sent by the base station in different locations, and parses and extracts the original IMEI information carried in the access request information. The original IMEI information of the user terminal A and the user terminal B is the same as the IMEI information stored in the identifier database, and the network device obtains the original IMEI information (IMEI_A) of the user terminal A and the access sequence number of the user terminal A (in FIG. 1). The access sequence number of the user terminal A is 1) and the network device information constructs the target IMEI information of the user terminal A, and the target IMEI information of the user terminal A is: IMEI_A_1; Similarly, the network device constructs the target IMEI information of the user terminal B. For: IMEI _A_2.

步骤 140、向所述网络中的周边网络设备发送所述目标 IMEI信息，以使所述周边网络设备利用所述目标 IMEI信息标识所述第一用户终端。 Step 140: Send the target IMEI information to a neighboring network device in the network, so that the neighboring network device identifies the first user terminal by using the target IMEI information.

具体地，根据步骤 130的描述，如图 2所示，网络设备构造完成所述目标 IMEI信息后，向网络中的周边网络设备发送目标 IMEI信息，以使第一用户终端后续通过网络设备访问周边网络设备时，周边网络设备利用所述目标 IMEI信息标识第一用户终端。 Specifically, according to the description of step 130, as shown in FIG. 2, the network device is configured to complete the mesh.
