Description

Method, device and system for controlling Machine Type Communication (MTC) terminal behaviors

Technical Field

The present invention relates to the field of machine type communication, and in particular, to a method, an apparatus, and a system for controlling a machine type communication MTC terminal behavior.

Background

MTC (Machine Type Communications) is a mode of communication between machines. For example, many intelligent instruments and meters have an RS-232 interface and a GPIB (General Purpose interface bus) communication interface, which enhances the communication capability between instruments and computers.

At present, most MTC applications, such as electronic meter reading and outdoor measurement, are mostly in a separated state between an MTC user and an MTC terminal, where the MTC user may be actually owned by the MTC terminal and may be a subscriber of the MTC terminal accessing to a network, for example, in the electronic meter reading application, the MTC user may be a power plant, and the MTC terminal may be a smart meter, and thus, the MTC user is difficult to control the behavior of the MTC terminal. When the MTC terminal is stolen or the configuration data is tampered with, and the MTC terminal accesses the current network, the current network performs access control on the MTC terminal to determine whether the MTC terminal is allowed to access the current network, for example, performs authentication processing to identify whether a USIM (Universal Subscriber Identity Module) of the terminal is legal, and if the MTC terminal is stolen or the configuration data is tampered with, but the USIM of the MTC terminal is still legal, the damaged MTC terminal may still pass authentication and may access the current network.

Therefore, at present, although the network performs access control on the MTC terminal, the network still cannot ensure the security and reliability of the MTC application, which affects the vital interests of the MTC user.

Example 2

Referring to fig. 3, this embodiment provides a method for controlling an MTC terminal behavior, where the method feeds back a control policy to a network side by updating MTC terminal subscription data based on an obtained monitoring result of the MTC terminal, so as to control the MTC terminal, and implement a dynamic policy control method, where the method includes:

101: the MTC server acquires a related monitoring result of the MTC terminal;

specifically, there may be multiple methods for acquiring the relevant monitoring result of the MTC terminal, and this embodiment does not limit the specific acquisition method, and the following two methods are taken as examples for description.

The first method is as follows: the MTC terminal monitors itself, and when abnormality occurs, the monitoring result is reported to the MTC server. For example, when the terminal is stolen, tampered and the like, the terminal sends alarm information to the MTC server, and reports the abnormal situation.

The second method is a method for reporting a monitoring result based on subscription event triggering, which is described in detail in steps 101a to 101d, referring to fig. 4, and specifically as follows:

101 a: the MTC server determines a monitoring event of the MTC terminal;

the monitoring event includes a monitoring trigger point, or called default information. And when the behavior of the terminal or the provided information meets the monitoring trigger point or is inconsistent with the default information, the mobile management equipment reports the monitoring result to the server.

The monitoring event of the MTC terminal may specifically be:

1) giving position information attached to the MTC terminal, namely default position information, and monitoring the current position of the MTC terminal;

2) giving a binding relationship between an IMSI (International Mobile Subscriber Identity) of an MTC terminal and an IMEI (International Mobile Equipment Identity), namely default binding information, and monitoring the binding relationship between the IMSI and the IMEI provided by an MTC terminal access network;

3) giving the capability information attached to the MTC terminal, namely default capability information, and monitoring the capability information of the MTC terminal;

the capability information of the MTC terminal may specifically be a wireless access capability, a TP (Internet Protocol) capability, and the like.

4) Given MTC features (characteristics), namely default characteristics, of the MTC terminals, the MTC features of the MTC terminals are monitored;

the MTC features specifically refer to application characteristics of the MTC terminal, for example, low data flow application, low mobility application, and the like.

Further, the monitoring event may be specifically other content, and is not limited to the above-mentioned list.

101 b: the MTC server subscribes a monitoring event of the MTC terminal to subscription data management equipment to which the MTC terminal belongs;

the subscription mode may be that after the MTC server negotiates with an MNO (Mobile Network Operator) to determine a monitoring event, the MNO subscribes the monitoring event of the MTC terminal to subscription data management equipment to which the MTC terminal belongs through a platform to which the MNO belongs; or, the subscription mode may also be that the mobile network operator provides a connection interface with the subscription data management device to which the MTC terminal belongs to the MTC server, and the MTC server subscribes the monitoring event of the MTC terminal to the subscription data management device to which the MTC terminal belongs through the connection interface. The specific subscription mode is not limited.

The subscription data management device may be an HLR (Home Location Register), an HSS (Home Subscriber Server), and the like, and the subscription data management device is different according to different access networks, and this embodiment does not limit a specific subscription data management device.

101 c: the subscription data management equipment updates the subscription data of the MTC terminal according to the subscribed monitoring event of the MTC terminal, and sends the updated subscription data, namely the subscription data containing the subscribed monitoring event of the MTC terminal to the mobility management equipment to which the MTC terminal belongs.

The Mobility Management device may be an SGSN (Serving General Packet Radio Service support node), an MME (Mobility Management Entity), and the like, and the Mobility Management device is different according to different access networks, and this embodiment does not limit a specific Mobility Management device.

Further, when the monitoring event of the MTC terminal subscribed by the MTC server changes, the subscription data management device to which the MTC terminal belongs and the mobility management device to which the MTC terminal belongs need to update the monitoring event of the subscribed MTC terminal synchronously.

101 d: and the mobility management equipment monitors the behavior of the MTC terminal according to the monitoring event of the MTC terminal subscribed by the MTC server in the updated subscription data, and reports the monitoring result to the MTC server when the monitoring trigger point is met or the monitoring trigger point is inconsistent with default information.

The monitoring result may include an indication that the monitoring event is abnormal, where the indication may be specifically implemented by a specific cell, and may also include monitoring event related information such as a current state of the monitoring event. The specific form of the monitoring result may be an alarm message, and the alarm message includes information related to the monitoring event. Corresponding to the monitoring event listed in step 101a, reporting the monitoring result specifically includes:

1) and when the position information attached to the MTC terminal is changed, namely the position information is not in accordance with the default position information, reporting the monitoring result. The monitoring result comprises an indication of change of location information attached to the MTC terminal, and may further comprise changed location information;

2) and when the binding relationship between the IMSI and the IMEI provided by the MTC terminal is changed, namely the binding relationship is not consistent with the default binding relationship, reporting the monitoring result. The monitoring result comprises an indication of the change of the binding relationship between the IMSI and the IMEI of the MTC terminal, and can also comprise the current binding relationship;

3) and when the capability information provided by the MTC terminal is changed, namely the capability information is not in accordance with the default capability information, reporting the monitoring result. The monitoring result comprises an indication of the change of the MTC terminal capability information and can also comprise current capability information;

4) and when the MTC features provided by the MTC terminal are changed, namely the MTC features are not in accordance with the default characteristics, reporting the monitoring result. The monitoring result comprises an indication that the MTC features are changed, and can also comprise the current MTC features;

the embodiment provides two modes for reporting the monitoring result:

the first method comprises the following steps: and the mobile management equipment reports the monitoring result to the subscription data management equipment, and the subscription data management equipment reports the monitoring result to the MTC server. In particular, the method comprises the following steps of,

1) the subscription data management device can report the monitoring result to the MTC server through 0M (Operation Maintenance); or,

2) and the contract data management equipment reports the monitoring result to the MTC server corresponding to the address information according to the recorded address information of the MTC server. The address information of the MTC server may be maintained in the subscription data of the MTC terminal, and the subscription data management device retrieves the subscription data of the terminal to obtain the address information of the MTC server.

And the second method comprises the following steps: the mobility management equipment acquires the address information of the MTC server and reports the monitoring result to the MTC server corresponding to the address information. Specifically, there are the following 3 approaches to obtain the address information of the MTC server:

1) the method comprises the steps that the mobile management equipment acquires address information of an MTC server from subscription data of subscription data management equipment;

2) the method includes that a mobility management device acquires address information of an MTC server from a Gateway device, for example, the address information of the MTC server is sent to the mobility management device in a response message of activating a bearer by the Gateway device P-GW (Packet Data Network Gateway) or GGSN (Gateway GPRS Support Node);

when the MTC terminal accesses the network, the gateway equipment to which the MTC terminal belongs establishes association between the MTC terminal and the MTC server. And the gateway equipment acquires the address information of the MTC server according to the local configuration or analysis of the identification information related to the terminal, such as IMSI, IMEI or APN.

3) The mobility management device obtains address information of the MTC server from the MTC terminal, for example, the MTC terminal initiates a procedure to the mobility management device, for example, the MTC terminal provides the address information of the MTC server to the mobility management device in an attach request message, a bearer activation request message, or a location update request message.

Specifically, the MTC terminal may obtain address information of the MTC server through default configuration or through DNS (Domain Name System) resolution.

The subscription data management device, the mobility management device, the gateway device, and the like are specific devices of the operator network. The operator network supporting MTC may be GSM (Global System for Mobile Communications), GPRS (General Packet Radio Service), UMTS (universal Mobile Telecommunications System), LTE (Long Term Evolution), etc., and the present embodiment does not limit specific operator network types.

102: and the MTC server acquires the abnormal behavior of the MTC terminal according to the monitoring result, and if the MTC server needs to limit the abnormal behavior of the MTC terminal, the terminal can be controlled in a mode of updating the subscription data of the MTC terminal.

Specifically, the subscription data of the MTC terminal may be updated to the subscription data management device through a 0M operation. In the step, the control strategy is fed back to the network side by updating the subscription data. For example: when the MTC server learns that the monitoring result of the MTC terminal is abnormal, the MTC server updates subscription data and does not allow the terminal to access the network; or, allowing the terminal to execute network attachment, but limiting PDN connection establishment of the terminal, allowing only some specific PDN connections to be established, rejecting unauthorized PDN connection establishment, for an already established unauthorized PDN connection, the network side needs to execute a corresponding release procedure;

further, when learning that the terminal behavior is abnormal, the MTC server may also receive the abnormal behavior of the MTC terminal, and in this case, the MTC server may update the monitoring event and subscribe the updated monitoring event to the mobile network. And the mobile network monitors the behavior of the terminal according to the updated monitoring event.

103: the subscription data management equipment synchronizes the updated subscription data of the MTC terminal to the mobility management equipment to which the MTC terminal belongs;

the mobility management device to which the MTC terminal belongs is a mobility management device that provides services for the MTC terminal.

104: and the mobile management equipment controls the MTC terminal according to the updated subscription data of the MTC terminal.

For example: if the updated subscription data indicates that the terminal is refused to access the network in the current area, the mobility management device can execute the process of separating the MTC terminal, so that the access of the MTC terminal in the current area is refused; or, the mobility management device confirms that an unauthorized PDN connection exists according to the updated subscription data, and may execute a procedure of releasing the established unauthorized PDN connection, and subsequently reject the request initiated by the terminal for establishing the unauthorized PDN connection; or, the mobility management device monitors the behavior of the terminal according to the updated monitoring event contained in the updated subscription data.

In the monitoring processing method provided by this embodiment, the MTC server obtains the monitoring result of the MTC terminal, updates the subscription data according to the monitoring result, and feeds back a control policy to the network side by updating the subscription data, so that the network side controls the MTC terminal according to the updated subscription data, and thus when the MTC terminal is abnormal, for example, stolen or tampered, the MTC server can obtain the abnormal information of the MTC terminal, and control the MTC terminal through the network, thereby ensuring the security and reliability of MTC application. The method provided by the embodiment can update the subscription data in real time according to the monitoring result, namely, adjust the Control strategy, is a dynamic strategy Control method, has the advantage of flexibility, and is suitable for a dynamic PCC (Policy and Charging Control) architecture model, a static PCC architecture model and a communication model without a PCC architecture.

Example 3

Referring to fig. 5, the present embodiment provides a method for controlling an MTC terminal behavior, where the method updates service information through a monitoring result, and feeds back a control policy to a network side through a method for updating the service information, so as to implement a dynamic policy control method, and for a dynamic PCC architecture model, the method includes:

201: the MTC server acquires a monitoring result of the MTC terminal;

the specific acquiring process is detailed in step 101, and is not described herein again.

202: the MTC server acquires abnormal behaviors of the MTC terminal according to the monitoring result, and can control the terminal in a mode of updating the service information. Specifically, the action of updating the service information may be that the MTC server interacts with a background management device of the operator and informs the operator of updating the service information, for example, terminating some services or modifying service attributes of some services, and the operator updates the service information to an AF (Application Function) entity or SPR (subscription profile Repository);

wherein, the step is to feed back the control strategy to the network side by updating the service information. If the Service information is updated to the SPR, because the Service information related to the terminal is stored in the SPR, the updated Service information may be to convert some subscribed services into unauthorized services or to modify Service attributes of some subscribed services, for example, QoS (quality of Service), QCI (QoS Class Identifier), ARP (address resolution Protocol) information, and the like; if the service information is updated to the AF, since the service information being executed by the terminal is recorded in the AF, the updated service information may be to end or terminate some currently activated services or to modify service attributes of some currently activated services, such as QoS, QCI, ARP information, and the like.

Wherein the MTC server itself may perform the function of the AF.

203: the AF/SPR updates the service information and notifies the PCRF (Policy and Charging Rules Function) of the updated service information. Here, it is required to correspond to the service information updated in step 202, and if the SPR updates the service information to the PCRF, the updated service information belongs to the service information of the subscription, for example, some subscribed services are converted into unauthorized services or service attributes of some subscribed services are modified; if the AF updates the service information to the PCRF, the updated service information belongs to the service information of the active service, e.g., ending or terminating some currently active services or modifying service attributes of some currently active services.

204: the PCRF updates the PCC according to the updated service information, and re-issues the PCC to a gateway device, such as a PGW (Packet Data network gateway). The PCC is to correspond to the service information updated in step 203, if the SPR updates the service information to the PCRF, and the PCRF confirms that the currently activated service belongs to the unauthorized service because the updated service information belongs to the subscribed service information, the PCC indicates to end or terminate the service, or the PCRF confirms that the service attribute of the currently activated service is changed, and the PCC includes the service attribute after the service is updated; if AF updates service information to PCRF, PCC indicates ending or stopping some currently activated services or modifies some service attributes of currently activated services.

205: the PGW receives the PCC issued by the PCRF, and initiates a corresponding bearer update procedure, for example, a bearer establishment, modification, or deletion procedure, according to the updated PCC. For example, the PCC indicates to end or terminate some currently activated services, and the PGW initiates a bearer modification or deletion procedure; the PCC includes service attributes for modifying some current activated services, the PGW initiates a bearer modification process, and the updated service attributes are synchronized to the corresponding bearers.

In the monitoring processing method provided by this embodiment, the MTC server obtains a monitoring result of the MTC terminal, updates service information to the network side according to the monitoring result, feeds back a control policy to the network side by updating the service information, triggers the gateway device to initiate a bearer update procedure, and when the MTC terminal is abnormal, for example, stolen or tampered, the MTC server can obtain the abnormal information and perform service control on the MTC terminal through the network, thereby ensuring the security and reliability of MTC application.

Example 4

Referring to fig. 6, the present embodiment provides a method for controlling an MTC terminal behavior, where the method updates service information through a monitoring result, and feeds back a control policy to a network side through a method for updating the service information, so as to implement a dynamic policy control method, and for a static PCC architecture model, the method includes:

301: the MTC server acquires a monitoring result of the MTC terminal;

302: the MTC server acquires abnormal behaviors of the MTC terminal according to the monitoring result, and can update the service information to the PGW in an OM (operation and maintenance) mode, wherein the updated service information belongs to the static service information stored on the PGW. For example, some services are converted to unauthorized services or service attributes of some services are modified, e.g., QoS, QCI, ARP information, etc.

Wherein, the step is to feed back the control strategy to the network side by updating the service information.

303: the PGW initiates a corresponding bearer update procedure, for example, a bearer establishment, modification, or deletion procedure, according to the updated service information. For example, the PGW determines that the currently activated service belongs to an unauthorized service according to the updated service information, and the PGW initiates a bearer modification or deletion procedure; and the PGW confirms that the service attribute of the current activated service changes according to the updated service information, initiates a bearer modification process, and synchronizes the updated service attribute to the corresponding bearer.

In the monitoring processing method provided by this embodiment, the MTC server obtains the monitoring result of the MTC terminal, updates the service information to the gateway side according to the monitoring result, feeds back a control policy to the network side in a manner of updating the service information, triggers the gateway device to initiate a bearer update procedure, and when the MTC terminal is abnormal, for example, stolen or tampered, the MTC server can obtain the abnormal information and perform service control on the MTC terminal through the network, thereby ensuring the safety and reliability of MTC application.

Example 5

Referring to fig. 7, this embodiment provides a method for controlling an MTC terminal behavior, where the method updates subscription data according to a monitoring result, and feeds back a control policy to a network side by using the method for updating subscription data, so as to implement a dynamic policy control method, and for a model without a PCC architecture, the method includes:

401: the MTC server acquires a monitoring result of the MTC terminal;

402: the MTC server learns the abnormal behavior of the MTC terminal according to the monitoring result, and updates the subscription data of the MTC terminal, as described in step 102;

the updated subscription data may include service-related subscription data, for example, some services are converted into unauthorized services or service attributes of some services are modified, for example, QoS, QCI, ARP information, and the like.

In the step, the control strategy is fed back to the network side by updating the subscription data.

403: the subscription data management equipment synchronizes the updated subscription data to the mobile management equipment;

404: the mobility management device initiates a bearer update procedure, such as a bearer establishment, modification, or deletion procedure, according to the service-related information included in the updated subscription data. For example, the mobility management device determines that the currently activated service belongs to an unauthorized service according to the updated service information, and the PGW initiates a bearer modification or deletion procedure; and the PGW confirms that the service attribute of the current activated service changes according to the updated service information, initiates a bearer modification process, and synchronizes the updated service attribute to the corresponding bearer.

In the monitoring processing method provided by this embodiment, the MTC server obtains the monitoring result of the MTC terminal, updates the subscription data related to the service to the gateway side according to the monitoring result, feeds back a control policy to the network side by the method of updating the subscription data, triggers the mobility management device to initiate a bearer update procedure, and when the MTC terminal is abnormal, for example, stolen or tampered, the MTC server can obtain the abnormal information and perform service control on the MTC terminal through the network, thereby ensuring the security and reliability of MTC application.

Example 6

Referring to fig. 8, the present embodiment provides a method for controlling an MTC terminal behavior, where the method implements a monitoring process by a static policy control method for pre-configuring a control policy, and specifically includes:

501: configuring a monitoring event and a corresponding control strategy in subscription data of the MTC terminal;

the monitoring event and the corresponding control policy may be configured in the subscription data management device. The monitoring event comprises a monitoring trigger point, and a corresponding control strategy can be formulated according to whether the terminal behavior meets the monitoring trigger point.

The control strategy is a control mechanism corresponding to the network side after the MTC terminal monitors the abnormal event.

502: monitoring events and corresponding control strategies are synchronously carried out on the mobility management equipment to which the MTC terminal belongs;

503: and the mobility management equipment executes control on the MTC terminal according to the monitoring event and the corresponding control strategy.
