Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method, an apparatus, and a system for limiting the number of times MTC devices move by a network.
Background
Fig. 1 is a schematic diagram of an architecture of an Evolved Packet System (EPS), as shown in fig. 1, an EPS of a third Generation Partnership Project (3rd Generation Partnership Project, abbreviated as 3GPP) is composed of an Evolved universal mobile telecommunications System Terrestrial Radio Access Network (E-UTRAN), a mobile Management unit (Mobility Management Entity, abbreviated as MME), a Serving Gateway (Serving Gateway, abbreviated as S-GW), a Packet Data Network Gateway (Packet Data Network Gateway, abbreviated as P-GW or PDN GW), a Home Subscriber Server (Home subscription Server, abbreviated as HSS), a Policy and Charging Rules Function Entity (Policy and Charging Rules Function, abbreviated as PCRF), a Serving GPRS service Node (GPRS Node, SGSN, and other support nodes. Wherein the Core network portion is referred to as Packet Core Evolution (EPC).
In fig. 1, an MME is responsible for operations related to a control plane, such as mobility management, processing of non-access stratum signaling, and management of context in user mobility management; the S-GW is an access gateway device connected with the E-UTRAN, forwards data between the E-UTRAN and the P-GW, and is responsible for caching paging waiting data; the P-GW is a border gateway between the EPS and a Packet Data Network (PDN for short), and is responsible for accessing the PDN and forwarding Data between the EPS and the PDN; the PCRF is a policy and charging rule function entity, and is connected to an operator network Protocol (Internet Protocol, abbreviated as IP) Service network through a receiving interface Rx to obtain Service information, and in addition, it may be connected to a gateway device in the network through a Gx interface to be responsible for initiating establishment of an IP bearer, ensuring Quality of Service (QoS) of Service data, and performing charging control. A GPRS service Support Node (SGSN) is an important component of a core network packet domain device in the UTMS/GSM system, and mainly completes functions such as routing forwarding, mobility management, session management, logical link management, authentication and encryption, ticket generation and output, etc. of a packet data packet, and is connected to a Home Location Register (HLR) through a Gr interface to perform access and access control of a user database. A Universal Terrestrial Radio Access Network (UTRAN for short) and a GSM (gprs)/EDGE Radio Access Network (GSM EDGE Radio Access Network for short) may be accessed into the EPS through the SGSN Access gateway device. The HSS is the evolution and upgrade of the HLR.
The definition of M2M in the narrow sense is machine-to-machine communication. The broad definition is networked applications and services with machine terminal intelligent interaction as core. The intelligent machine terminal-based intelligent data acquisition and measurement system is an informatization solution scheme provided for clients by taking various communication modes as access means, and is used for meeting informatization requirements of the clients on monitoring, command scheduling, data acquisition, measurement and the like.
The development of the wireless technology is an important factor for the development of the M2M market, and the wireless technology breaks through the space-time limitation and the geographical barrier of the traditional communication mode, so that enterprises and the public get rid of the cable constraint, customers can more effectively control the cost, the installation cost is reduced, and the use is simple and convenient. In addition, increasing demand is driving M2M to continue to evolve forward: contrary to the increasing information processing capacity and network bandwidth, the means of information acquisition is far behind. And M2M well meets the requirement of people, and people can monitor the external environment in real time through the device, thereby realizing large-range and automatic information acquisition. Thus, M2M may be applied to industrial applications, home applications, personal applications, and the like. Industrial applications are as follows: traffic monitoring, alarm systems, rescue at sea, vending machines, driving payment, etc. Household applications are as follows: automatic meter reading, temperature control and the like. Personal applications such as: life detection, remote diagnostics, etc.
The communication target of M2M is machine-to-machine, and human-to-machine. Data Communication between one or more machines is defined as MTC (Machine Type Communication), in which case human-Machine interaction is less required. And the machine participating in MTC is defined as MTC equipment. An MTC device (MTC UE) is a terminal of an MTC user, and may communicate with the MTC device and an MTC server through a PLMN network. Fig. 2 is a schematic diagram illustrating an MTC UE accessing an EPS through EUTRAN in the prior art. Fig. 3 is a diagram illustrating an MTC UE accessing a GPRS system through a UTRAN in the prior art.
An important feature in M2M communications is low mobility, which may or may not be moving within a specified range. For devices with low mobility, the network needs to sense the movement of the device, such as limiting the moving range of the MTC device, or limiting the moving times of the MTC device. Of course, there is also an MTC device without mobility, and in this case, if the MTC device moves, the network considers that the device is abnormal. The prior art does not have a complete solution when the network needs to limit the number of moves of MTC devices.

Among them, the present invention can have two preferable implementation modes:
the first method is as follows:
the MTC equipment initiates an attachment request to the mobility management network element, the mobility management network element judges whether the MTC equipment moves, if so, the mobility management network element judges whether the moving times of the MTC equipment exceeds the moving times allowed by the MTC equipment subscription according to the moving times of the MTC equipment stored locally, and if so, the mobility management network element rejects the MTC equipment to access a network.
Preferably, the step of determining, by the mobility management network element according to the number of times that the MTC device has moved, which is locally stored, whether the number of times that the MTC device has moved exceeds the number of times that the MTC device has signed a subscription allows includes:
the mobility management network element updates the locally stored number of times that the MTC equipment has moved, judges whether the number of times that the MTC equipment has moved is greater than the number of times that the MTC equipment signs a contract to allow to move, and if so, judges that the number of times that the MTC equipment has moved exceeds the number of times that the MTC equipment signs a contract to allow to move; or,
the mobility management network element firstly judges whether the number of times that the MTC equipment has moved, which is locally stored, is less than the number of times that the MTC equipment is signed and allowed to move, and if so, the number of times that the MTC equipment has moved, which is locally stored, is updated; if not, judging that the moving times of the MTC equipment exceed the moving times allowed by the MTC equipment subscription.
Preferably, after the MTC device is detached, the mobility management network element updates the number of times that the MTC device has moved to a user database.
Further, when the MTC device is detached and then attached again, which causes a change in the mobility management network element, the target mobility management network element obtains the number of times that the MTC device has moved from the user database, and stores the number of times in the local area.
Preferably, when the MTC device is detached and then attached again, or the location of the MTC device is updated, which causes a change in the mobility management network element, the target mobility management network element obtains the number of times that the MTC device has moved from the original mobility management network element, and stores the number of times in the local area.
The second method comprises the following steps:
after the MTC equipment initiates an attachment request or a position updating request to the mobility management network element, the mobility management network element judges whether the MTC equipment moves, and if so, a user database is notified;
the user database judges whether the moving times of the MTC equipment exceed the moving times allowed by the MTC equipment subscription according to the locally stored moving times of the MTC equipment, and informs the mobility management network element;
and the mobility management network element acquires the judgment result of the user database, and if the movement times of the MTC equipment exceed the movement times allowed by the subscription, the mobility management network element rejects the MTC equipment to access the network.
Preferably, the step of the user database judging whether the number of times of movement of the MTC device exceeds the number of times of movement allowed by the subscription of the MTC device according to the locally stored number of times of movement of the MTC device specifically includes:
the user database updates the locally stored number of times that the MTC equipment has moved, judges whether the number of times that the MTC equipment has moved is larger than the number of times that the MTC equipment signs a contract to allow to move, and if so, judges that the number of times that the MTC equipment has moved exceeds the number of times that the MTC equipment signs a contract to allow to move; or,
the user database firstly judges whether the number of times that the MTC equipment is moved and stored locally is smaller than the number of times that the MTC equipment is signed and allowed to move, and if so, the number of times that the MTC equipment is moved and stored locally is updated; if not, judging that the moving times of the MTC equipment exceed the moving times allowed by the MTC equipment subscription.
In the present invention, preferably, the mobility management network element compares the current user location information of the MTC device with a subscription list, and determines whether the MTC device moves.
When the MTC device initiates an attach request to the mobility management network element, the rejecting, by the mobility management network element, the MTC device to access the network means: the mobility management network element refuses an attachment request of the MTC equipment;
when the MTC device initiates a location update request to the mobility management network element, the rejecting, by the mobility management network element, the MTC device to access the network means: and the mobility management network element initiates a detach process of the MTC equipment.

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not limited to the present invention.
Example one
In this embodiment, when the MTC UE is attached, the mobility management network element limits the number of MTC UE movements. The mobility management network element receives an attachment request of the MTC UE and judges whether the MTC UE moves. If the MTC UE moves, the mobility management network element judges whether the movement times of the MTC UE exceed the movement times allowed by the MTC UE subscription according to the locally stored movement times of the MTC UE, and if the movement times of the MTC UE exceed the movement times allowed by the MTC UE subscription, the mobility management network element rejects the attachment request of the MTC UE. Fig. 4 is a flowchart of an embodiment of the present invention, which specifically includes the following steps:
step 401: the MTC UE initiates an attachment request message;
step 402: if the mobility management network element changes due to detachment, the target mobility management network element sends an identification request message to the original mobility management network element, and the original mobility management network element sends an identification response message to the MTC UE, wherein the message contains the number of times that the MTC UE has moved;
step 403: if the mobility management network element is changed or is attached for the first time, the mobility management network element sends a location updating message to a user database, and a location updating response message returned by the user database carries the number of times of subscription permission of MTC UE to move;
if the position is updated due to the change of the mobility management network element and the user database records the number of times that the MTC UE has moved, the position update response also carries the number of times that the MTC UE has moved;
step 404: the mobility management network element compares the current user position information with the signed list, judges whether the MTC UE moves, if the MTC UE moves, and does not reach the movement times allowed by the subscription, the mobility management network element updates the locally stored movement times of the MTC UE, and executes step 406; if the number of times of movement allowed by the subscription is reached or exceeded, the mobility management network element executes step 405;
step 404 may also be performed as follows according to step 404':
step 404': the mobility management network element compares the current user position information with a signed list, judges whether the MTC UE moves, if so, updates the locally stored moved times of the MTC UE, then judges whether the moved times is greater than the movement times allowed by the signed MTC UE, if so, executes step 405, otherwise, executes step 406;
step 405: and the mobility management network element rejects the attach request of the MTC UE, the reject request carries a cause value, and subsequent steps are not executed.
Step 406: the subsequent process of the attach flow continues.
Example two
In this embodiment, when the location of the MTC UE is updated, the mobility management network element limits the number of MTC UE movements. When the MTC UE performs location update, the mobility management network element changes, and the target mobility management network element needs to request the original mobility management network element for the number of times that the MTC UE has moved. Fig. 5 is a flowchart of an embodiment of the present invention, which specifically includes the following steps:
step 501: when the MTC UE detects that a new location area changes and the current location area identification of the UE is not in a location list of a UE registration network, the UE starts to trigger a location updating process. The MTCU sends a position updating request to a target mobility management network element;
step 502: the target mobility management network element sends a context request message to the original mobility management network element to obtain user information;
step 503: the original mobility management network element returns a context response message to the target mobility management network element, wherein the message comprises the number of times that the MTC UE has moved and the number of times of subscription permission;
step 504: the mobility management network element compares the current user location information with the signed list, judges whether the MTC UE moves, if the MTC UE moves and does not reach the movement times allowed by the subscription, the mobility management network element updates the locally stored movement times of the MTC UE, and executes step 506; if the number of times of movement allowed by the subscription is reached or exceeded, the mobility management element performs step 505;
step 504 may also be performed as follows, step 504':
step 504': the mobility management network element compares the current user location information with a signed list, judges whether the MTC UE moves, if so, updates the locally stored number of times that the MTC UE has moved, then judges whether the number of times that the MTC UE has moved is greater than the number of times that the MTC UE has signed and allowed, if so, executes step 505, otherwise, executes step 506;
step 505: and the mobility management network element initiates the detach flow of the MTC UE, and does not execute the subsequent steps.
Step 506: the subsequent process of the location update procedure is continued.
EXAMPLE III
In this embodiment, after the MTC UE is detached, the mobility management network element updates the number of times that the MTC UE has moved in the user database. When the mobility management network element informs the user database to delete the subscription data and the mobility management context of the detach user, the user database needs to be informed to store the number of times that the MTC UE has moved. Fig. 6 is a flowchart of an embodiment of the present invention, which specifically includes the following steps:
step 601: after deleting the subscription data and the mobile management context of the detached user, the mobile management network element sends a message of removing the MTC UE to a user database, wherein the message carries the number of times that the MTC UE has moved;
step 602: and the user database marks the MTC UE as cleared, records the number of times that the MTC UE has moved, and returns a clearing confirmation message to the mobility management network element.
Example four
In this embodiment, the mobility management network element does not store the number of times that the MTC UE has moved, but stores the number of times that the MTC UE has moved by the user database, so as to limit the number of times that the MTC UE has moved. When the mobility management network element identifies the movement of the MTCUs, the user database is informed through the indication, the user database judges whether the movement times of the MTC UEs are out of limit or not, and the mobility management network element is informed through the indication. And the mobility management network element judges the indication returned by the user database, and if the indication is exceeded, rejects the attachment request of the MTC UE or initiates the detachment process of the MTC UE. Fig. 7 is a flowchart of the method of the present invention, which specifically includes the following steps:
step 701: after the MTC UE initiates an attach request or a location update request to the mobility management network element, the mobility management network element compares the current user location information with the subscribed list to determine whether the MTC UE moves, and if so, notifies the user database through step 702;
step 702: a mobility management network element initiates a location update request to a user database, wherein the request carries an identifier indicating whether the MTC UE moves (namely an MTC equipment moving identifier);
step 703: and the user database judges whether the MTC UE moves according to the MTC UE moving identification. If the MTC UE moves, the number of times of the local movement of the MTC UE is compared with the number of times of subscription permission of the MTC UE, and if the number of times of the local movement of the MTC UE does not reach the number of times of subscription permission, the number of times of the local movement of the MTC UE is updated; if the number of times of movement allowed by the subscription is reached or exceeded, the number of times of movement of the MTC UE is exceeded;
step 703 may also be performed according to the following step 703':
step 703': and the user database judges whether the MTC UE moves according to the MTC UE moving identification. If the MTC UE moves, updating the number of times that the MTC UE has moved which is stored locally, and then judging whether the number of times that the MTC UE has moved is larger than the number of times that the MTC UE has signed a contract and allowed to move, if so, the number of times that the MTC UE has moved is out of limit;
step 704: the user database sends a position updating response to the mobility management network element, and the response carries an indication whether the MTC UE moving times are over;
step 705: the mobility management network element judges the indication that the movement times of the MTC UE exceed the limit, and if the indication exceeds the limit, the mobility management network element sends attachment rejection or initiates a detachment process to the MTC UE according to the current state;
if the MTC UE is in the attachment process, sending an attachment rejection response to the MTC UE; and if the MTC UE is in the position updating process, initiating a detach process to the MTC UE.
