Description

Method and device for checking mobile device

Technical field

The present invention relates to the field of network communication technologies, and in particular, to a method and apparatus for inspecting a mobile device. Background technique

In the communication system, for a mobile terminal in which the card is integrated, the MSID (Mobile Station Identity) and the ESN (Electronic Serial Number) are bound together, and therefore, only need to be in the HLR ( The home location register, the home location register) can realize the management of the MSID, and the management of the terminal can be realized; but after the machine card is separated, the user identifier MSID and the capability of the UIM (User Identity Module) card are equipped. There is no necessary connection between mobile devices. Users can change mobile devices or UIM cards at any time. However, since mobile devices may be stolen and stolen, if they are not verified, these illegal mobile devices will still be normal. In addition, due to the relatively high cost of mobile devices and the low cost of UIM cards, some criminals may use the same mobile device, but frequently change different UIM cards to make calls to avoid being monitored or operated by the police. The call is forbidden, so the check of the mobile device ESN is very Necessary.

3GPP2 (3rd Generation Partnership Project2) The N.S0004 protocol mainly describes the mobile user identification module UIM. Users can change different UIM cards on the same mobile station MS (Mobile Station). The basic process is shown in Figure 1:

A-b, the user removes the UIM card from the ME-1 and inserts it into the ME-2;

C-f and ME-2 calculate the authentication result, and initiate location registration, and the message includes information such as an authentication result and a device number;

Gi, the service MSC (Mobile Switch Center) sends an authentication request message to the service VLR (Visitor Location Register), the VLR forwards it to the home location register HLR, and the HLR forwards it to the AC (Authentication) Center, authentication center), the user is authenticated by the AC;

j, AC calculates the authentication result and compares it with the authentication result sent by ME-2, and returns the comparison result to the HLR;

K-l, authentication succeeded, the HLR finds that the user uses the different ESN for registration in the service system, and sends a location registration cancellation message to the VLR to cancel the current registration record, which includes the previous ESN1; the VLR forwards to the serving MSC;

Mn, the service MSC clears the corresponding record and returns a location registration cancellation response message to the VLR; after the VLR clears the corresponding record, it returns a location registration cancellation response message to the HLR; after the op, the authentication and the cancellation of the original registration information are successfully processed, the HLR will process the new ESN. (ie, ESN2) is bound to the user; and returns an authentication response message to the serving VLR; the VLR is forwarded to the serving MSC;

Q-r, the service MSC sends a location registration request message to the VLR for location registration, and the VLR is forwarded to the HLR;

After s-t, the HLR registers to return a location registration response message, which contains user data information; the VLR pre-transmits regnot to the serving MSC.

The inventor has found that at least the following problems exist in the prior art: In the existing location registration process after replacing the UIM card, after the authentication succeeds, it is determined that the user uses different electronic serial numbers for registration, and only the new ESN is updated, and then , still registering for location. It can be seen that the legality of the mobile device is not checked in the process, and the mobile device cannot be configured with a whitelist or a blacklist. The mobile device cannot be managed, and the illegal mobile device cannot be prohibited from being used in the network. Summary of the invention

As shown in FIG. 3, a flowchart of a method for inspecting a mobile device according to an embodiment of the present invention includes the following steps:

Step S301: The EIR receives a request sent by the network device to check the identity of the mobile device. The network device may include an MSC HLR AC or a VLR, and the mobile device identifier that the MSC HLR or AC requests to check is a MEID or an ESN, and the mobile device identifier that the VLR requests to check is an ESN. In the location registration or call procedure, the MSC HLR AC or VLR receives the location registration request or call request information sent by the mobile device and then sends a request to the EIR to check the mobile device identity. The EIR is a logical function entity, which can be set separately for a network entity, and can also be set in any other network device. The network device in the embodiment of the present invention may be an MSC HLR AC or a VLR, but is not limited thereto. Before sending a request for checking the identity of the mobile device to the EIR, the network device is legal according to the preset check location registration validity or the call request. The sexual configuration determines whether the mobile device identity needs to be verified, and if so, sends a request to the EIR to check the mobile device identity.

In the embodiment of the present invention, the network device initiates a request for checking the identity of the mobile device, and the check process is not limited to the following scenarios: According to the configuration requirements of the operator, for example, some operators may only need to check the legality during the call, and some may require The validity of the location check is checked. At this time, the network device verifies the validity of the mobile device identity in the call flow or location registration process, and sends a request to the EIR to check the mobile device identity. In addition, the operator can also configure whether the mobile device identity needs to be verified in the network device.

Step S302: The EIR checks the mobile device identity according to the MEID or ESN in the request for checking the identity of the mobile device, and returns the mobile device information to the network device. among them, The mobile device information includes the inspection result of the EIR. The check of the mobile device identifier may be that the corresponding user equipment identifier stored in the query is consistent with the MEID or the ESN in the request for checking the mobile device identifier. At this time, the mobile device information is information indicating whether the mobile device identifier is consistent, and the MSC The HLR, AC or VLR processes the location registration request or the call request of the mobile device based on the mobile device information returned by the EIR. Specifically, the MSC, the HLR, the AC, or the VLR checks the mobile device information, and determines whether the state of the mobile device is legal according to the mobile device information returned by the EIR. If it is legal, the location registration request or the call request process is continued;

If it is determined that the state of the mobile device is illegal, the network device rejects the location registration request or the call request.

In the first embodiment of the present invention, an interface message between the MSC/HLR/AC and the EIR is added to detect the mobile device identifier (the mobile device number MEID or the electronic serial number ESN). Further, the status information of the corresponding mobile device of the MEID or the ESN may be saved in the EIR, such as the stolen information, and the check of the mobile device identifier may also be performed by querying the user according to the MEID or ESN in the request for checking the identity of the mobile device. The corresponding mobile device status information is identified. If the MEID or ESN is found to have been stolen, the status of the mobile device is illegal. Otherwise, the status of the mobile device is considered to be legal. Alternatively, the range of the legal MEID or ESN is set in the EIR. Only the corresponding mobile device of the MEID or ESN in this range is legal, otherwise it is illegal. At this time, the returned mobile device information is the MEID or ESN corresponding mobile device included in the request for checking the mobile device identification. Whether the status is legal or not.

As shown in FIG. 4, it is a schematic diagram of adding an interface message between an MSC/HLR/AC and an EIR according to Embodiment 1 of the present invention, which specifically includes the following steps:

Step S401, the MSC/HLR/AC sends a CHECKMEID to the EIR, which may include a MEID or an ESN;

Step S402, the EIR checks to return the corresponding mobile device information.

The MSC/HLR/AC then processes it based on the mobile device information. For example: when it is determined that the state of the mobile device is illegal according to the mobile device information, the MSC may reject the location registration request; when it is determined that the state of the mobile device is legal according to the mobile device information, the MSC continues Location registration process.

The second embodiment of the present invention extends the parameters in the interface CHECKMEID message between the VLR and the EIR, that is, the ESN parameter can be carried in the CHECKMEID message, so that the EIR can check the ESN; or similar to the first embodiment, a new opcode is defined, for example, Create an interface message between the VLR and the EIR to detect the ESN. As shown in FIG. 5, it is a schematic diagram of an interface between an extended VLR and an EIR according to Embodiment 2 of the present invention, which specifically includes the following steps:

Step S501: The VLR sends a CHECKMEID to the EIR, which may include an ESN. Step S502: The EIR checks to return the corresponding mobile device information.

The VLR then processes it based on the mobile device information. For example: When it is determined that the state of the mobile device is illegal according to the mobile device information, the VLR feeds back authreq to the MSC, indicating that the authentication fails, and the MSC finds that the authentication fails, and rejects the location registration request. When it is determined that the state of the mobile device is legitimate based on the mobile device information, the VLR continues the location registration process.

As shown in FIG. 6, it is a flowchart of user location registration for mobile device check by the MSC according to the second embodiment of the present invention, which specifically includes the following steps:

Identification ( ESN or MEID ).

Step S602, the EIR checks, and returns corresponding mobile device information.

Step S603, the serving MSC checks the mobile device information and performs corresponding processing. When it is determined that the state of the mobile device is illegal according to the mobile device information, step S604 is performed; when it is determined that the state of the mobile device is legal according to the mobile device information, step S605 is performed.

Step S604, the MSC rejects the location registration request.

Step S605, the location registration process is continued. The MSC sends an AUTHREQ to the HLR through the VLR. After accepting the location registration request, the HLR feeds back authreq to the MSC through the VLR, and then the MSC returns a register accept message (register accept) to the MS.

As shown in FIG. 7 , it is a flowchart of user location registration for performing mobile device check by a VLR according to Embodiment 2 of the present invention, which specifically includes the following steps: Step S701, the serving MSC sends an authentication request AUTHREQ to the VLR when receiving the registration request or the initial call request sent by the mobile station MS;

Step S702: The VLR determines, according to a preset configuration related to checking the legality of the call, that the mobile device identifier needs to be verified, and sends a CHEKMEID to the EIR, where the mobile device identifier (ESN) is included;

Step S703, the EIR checks, and returns corresponding mobile device information.

Step S704, the service VLR checks the mobile device information and performs corresponding processing. When it is determined that the state of the mobile device is illegal according to the mobile device information, step S705 and step S706 are performed; when it is determined that the state of the mobile device is legal according to the mobile device information, step S707 is performed.

Step S705: The VLR feeds back authreq to the MSC, where the authentication fails. In step S706, the MSC finds that the authentication fails, and rejects the location registration request.

Step S707, the location registration process is continued. The VLR sends an AUTHREQ to the HLR. After accepting the location registration request, the HLR feeds back the AUTHREQ to the VLR. The VLR feeds back authreq to the MSC, indicating that the authentication is successful, and the MSC finds that the authentication is successful, and returns a registration accept message (register accept) to the MS.

For device number detection by HLR or AC, it is similar to the above procedure, except that it is judged whether the checkpoint to be verified is at the HLR or AC, not the MSC.

As shown in FIG. 8, the third embodiment of the present invention further provides an apparatus for checking the legitimacy of a mobile device, including a receiving module and a processing module, where the receiving module is configured to receive a check mobile device number MEID or an electronic serial number ESN sent by the network device. Or a request to check the electronic serial number ESN sent by the location register VLR; the processing module is configured to perform the check according to the request and return the mobile device information.

The processing module further includes a check submodule and a feedback submodule, wherein the check submodule is configured to check the legality of the MEID or the ESN according to the request, that is, check the stored corresponding user equipment identifier and the request for checking the mobile device identifier Whether the MEID or the ESN is consistent; or checking the mobile device status information of the user according to the MEID or ESN in the request for checking the identity of the mobile device, whether it belongs to the stolen mobile device identifier; or in the request for checking the mobile device identity Is the MEID or E SN at the legal MEID or Within the scope of the ESN; the feedback sub-module is configured to generate a return message according to the check result of the check sub-module (legal or illegal), and return the mobile device information to the network device.

For example, in the location registration process shown in FIG. 6 and FIG. 7, the receiving module receives a request for checking the mobile device identity sent by the network device, and then the processing module performs the check according to the request and returns information corresponding to the mobile device. The network device further processes according to whether the mobile device information returned by the EIR is legal: if it is determined that the state of the mobile device is legal according to the mobile device information, the location registration process is continued, and if the state of the mobile device is determined to be illegal according to the mobile device information, the location is rejected.
