The foregoing mobile communication network and the first network element are only a few examples of the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

In this embodiment, the access restricted state may be that the MTC device cannot perform network attachment normally. When the MTC device in the restricted access state needs to report the alarm information to the MTC server, the process of attaching to the network needs to be completed first. Therefore, the MTC device needs to send an alarm attach request. The alarm attach request can not only have the function of attaching a request in the prior art, but also can be used to indicate that the MTC device needs to report the alarm information to the MTC server.

In this embodiment, when the MTC device is in the access restricted state, in order to report the alarm information to the MTC server through the mobile communication network, an alarm attach request needs to be sent to the first network element in the mobile communication network.

In this embodiment, the alarm attach request may be a message different from the attach request in the prior art. For example, the alarm attach request may be a PAM Attach Request, where the PAM Attach Request is in the PAM Attach Request.

Step 301: The MTC device sends an alarm attachment request to the first network element when the MTC device is in the access restricted state. In this embodiment, when the MTC device is abnormal, the alarm information is reported to the MTC server, and the alarm information may be used to indicate Out of the abnormal situation of the MTC device. If the MTC device knows that it is in a restricted state and fails to attach to the network, the alarm attach request is sent to the first network element to request to perform the process of attaching to the network. The abnormality of the MTC device may be: the theft of the MTC device or the destruction of the MTC device, for example: the MTC device is damaged, and the module of the universal integrated circuit card (hereinafter referred to as: UICC) of the MTC device is destroyed. .

The manner in which the MTC device confirms that the access is restricted is: 1) When the MTC device attempts to access the mobile communication network normally, the mobile communication network cannot be normally accessed due to the failure of the security authentication or the failure of the access authentication. For example, the MTC device sends an attach request message or a location update request message to the mobile communication network, and the mobile communication network fails to perform the security authentication of the MTC or the access authentication fails, so that the MTC device cannot complete the network attachment, and then the MTC device receives the mobile communication network and returns. The attach request rejection message or the location update request rejection message confirms that it is in an access restricted state. 2) The MTC device finds that there is currently no suitable mobile communication network to camp on, that is, the MTC device fails to select the network. For example, the MTC device does not find the currently received network identifier in the list of accessible network identifiers saved by itself, and thus confirms that it is in the restricted access state. The network identifier 歹 'J table may be a Public Land Mobile-communication Network List (hereinafter referred to as PLMN List), and the network identifier may be a PLMN ID. 3) The MTC device finds that its own UICC module is corrupted, that is, it is in the state of no UICC (UICC-Less), thus confirming that it is in an access restricted state. The manner in which the MTC device confirms that the access is restricted is not limited to the three cases listed above. In actual applications, the access restricted state may be confirmed by other means, which is not described here.

For the description of the alarm attachment request, refer to the first embodiment, and details are not described herein again. The device identification information may be an international mobile subscriber identity (IMSI) or an International Mobile Equipment Identity (IMEI). In the embodiment of the present invention, the alarm access request may also use other forms of messages, specifically no longer enumerated.

Step 302: The first network element sends an update location request message (Update Location Request) to the second network element, where the update location request message includes alarm attachment information.

In this embodiment, when the alarm attachment request is not included in the alarm attachment request, the alarm attachment letter The information may be generated by the first network element according to the alarm attachment request. Or, when the alarm attachment request includes the alarm attachment information, the first network element may directly obtain the alarm attachment information from the alarm attachment request after receiving the alarm attachment request.

In this embodiment, when the alarm attachment information includes an alarm attachment indication, the location update request message may include a cell "PAM At tach indica ion", ^τ "PAM At tach", the "ΡΑΜ At tach indica t ion" "Or "PAM At tach" is an alarm attachment indication. Or set the cell "ULR-Flags" of the location update request message to "PAM At tach", which is the alarm attachment indication. The alarm attachment indication in the alarm attachment information may be used to instruct the MTC device to request to perform the process of attaching to the network to report the alarm information to the MTC server.

Step 303: The second network element determines, according to the alarm attachment information, that the MTC device is allowed to perform an alarm attachment.

Specifically, step 303 includes:

Step 3031: The second network element learns, according to the alarm attachment indication in the alarm attachment information, that the MTC device performs alarm attachment.

In the prior art, when the MTC device is in the access restricted state, the second network element returns a rejection indication to the first network element, for example, the second network element returns an update location confirmation message to the first network element (Upda te Loca t ion Ack ) , the update location confirmation message includes a rejection indication, specifically, the update location confirmation message carries the cell “Resul t”, the “Resul t” is set to “errors”, and the “errors” is the rejection indication. . Further, the reason for rejection can be further indicated in "errors". However, in the embodiment of the present invention, the second network element can learn that the MTC device performs the alarm attachment according to the alarm attachment indication in the alarm attachment information, because the update location request message sent by the first network element includes the alarm attachment information, and thus Returning a rejection indication to the first network element.

Step 3032: The second network element determines, according to the pre-stored subscription data, whether the MTC device is allowed to perform alarm attachment.

After the second network element learns that the MTC device performs the alarm attachment, the second network element may query the subscription data corresponding to the device identification information in the alarm attachment information from the pre-stored subscription data, and the device identifier. The subscription data corresponding to the information may include information allowing the execution of the alarm attachment or information allowing the execution of the alarm service. For example, the information allowing the execution of the alarm attachment and the information allowing the execution of the alarm service may include the APN information, the PDN connection subscription information, and the QoS information. Billing information, etc., where the alarm service can be a PAM service. If the subscription data corresponding to the device identification information includes the information that allows the alarm to be attached or the information that allows the alarm service to be performed, the second network element determines that the MTC device is allowed to perform the alarm attachment; if the device identification information corresponds to the subscription data, The second network element determines that the MTC device is not allowed to perform the alarm attachment, that is, the second network element rejects the MTC device to perform the alarm attachment.

The embodiment of the present invention is described by taking an example of determining that the MTC device is allowed to perform alarm attachment according to the subscription data.

Step 304: The second network element returns an update location confirmation message (Upda te Loca t ion Ack) to the first network element.

In this embodiment, the update location confirmation message includes a success indication, where the success indication is used to indicate that the second network element allows the MTC device to attach to the network. Specifically, the update location confirmation message may include a cell "Resul t", the cell "Resul t" is set to "Succes s", and the "Succes s" is a success indication to indicate that the update location request is successful.

Optionally, the second network element may only transmit information that allows the alarm to be attached or the information that allows the alarm service to be performed in the subscription data corresponding to the device identification information. One network element.

In this step, if the second network element rejects the MTC device to perform the alarm attachment, the second network element returns a rejection indication to the first network element. Specifically, the second network element returns an update location confirmation message to the first network element, where the update location confirmation message includes a rejection indication, and the update location confirmation message may include a cell

"Resul t", "Resul t" is set to "errors" and the "errors" is 4 giant instructions. Further, the "errors" can indicate the reason for the rejection.

Step 305: The first network element returns an alarm attachment accept message to the MTC device.

After receiving the update location confirmation message, the first network element updates the location confirmation message to indicate an update. If the location request is successful, an alarm attach accept message may be returned to the MTC device.

In this step, if the first network element receives the rejection indication sent by the second network element, it returns a rejection indication to the MTC device to reject the access of the MTC device, and the process ends.

Step 306: The MTC device sends the alarm information to the first network element.

After receiving the alarm attachment accept message returned by the first network element, the MTC device learns that the alarm is successfully attached, and sends an alarm message to the first network element. The MTC device may send the alarm information to the first network element by using a Non-Access Layer (NAS) message. Specifically, the NAS message may include the alarm information, and the NAS message may be Sending to the first network element, the alarm information is sent to the first network element. The NAS message may be an Up NAS message (Up 1 ink NAS Trans por t ).

1) The alarm information sent by the MTC device is the alarm information identified by the MTC server;

2) The alarm information sent by the MTC device is the alarm information that cannot be identified by the MTC server. Specifically, the alarm information sent by the MTC device may be the alarm information identified by the first network element.

Step 307: The first network element sends the alarm information to the MTC server.

When the alarm information sent by the MTC device is the alarm information identified by the MTC server, the first network element directly transmits the alarm information to the MTC server.

When the alarm information sent by the MTC device is the alarm information that cannot be recognized by the MTC server, the first network element converts the alarm information sent by the MTC device into the alarm information identified by the MTC server, and sends the alarm information identified by the converted MTC server. The MTC server is sent to send the alarm information to the MTC server. For example, the alarm information that is identified by the first network element may include the specific value of the alarm type (PAM Type) agreed upon by the MTC device and the first network element. When the value of the PAM type is 1, the MTC device is stolen. When the first network element receives the alarm information identified by the first network element, the first network element needs to reconstruct the alarm information identified by the first network element to generate an alarm recognized by the MTC server. Information, that is, the first network The alarm information of the meta-identification is converted into the alarm information recognized by the MTC server, and the alarm information recognized by the MTC server is sent to the MTC server, so that the alarm information is sent to the MTC server.

In this embodiment, the first network element may send the alarm information to the MTC server according to the address information of the MTC server. For example, the first network element can locally configure the address information of the MTC server, obtain the address information of the MTC server from the MTC device, or obtain the address information of the MTC server from the second network element. The first network element may obtain the address information of the MTC server from the update location confirmation message returned by the second network element, and send the alarm information to the MTC server corresponding to the address information of the MTC server. Specifically, the address information of the MTC server returned by the second network element to the first network element may be included in the subscription data corresponding to the device identification information in the update location confirmation message, and the first network element may be returned from the second network element. The address information of the MTC server is obtained from the subscription data corresponding to the device identification information.

In the step 307 of the embodiment, the sending, by the first network element, the alarm information to the MTC server includes: directly sending the alarm information to the MTC server; or the first network element sends the alarm information to the MTC server by using the second network element, specifically The first network element sends the alarm information to the second network element, and the second network element sends the alarm information to the MTC server; or the first network element sends the alarm information to the MTC server through the third network element, specifically, the first The network element sends the alarm information to the third network element, and the third network element sends the alarm information to the MTC server.
