Embodiment 1

[0074] In this embodiment, when the MTC UE is attached, the mobility management network element limits the number of times the MTC UE moves. Wherein, the mobility management network element receives the attach request of the MTC UE, and judges whether the MTC UE is moving. If moving, the mobility management network element judges whether the number of times the MTC UE has moved exceeds the number of times the MTC UE has moved according to the number of times the MTC UE has moved locally, and if it exceeds, the mobility management network The element rejects the attach request of the MTC UE. Figure 4 It is a flowchart of an embodiment of the present invention, specifically including the following steps:

[0075] Step 401: MTC UE initiates an attach request message;

[0076] Step 402: If the mobility management network element changes due to detachment, the target mobility management network element will send an identification request message to the original mobility manageme...

Embodiment 2

[0085] In this embodiment, when the location of the MTC UE is updated, the mobility management network element limits the number of times the MTC UE moves. When the MTC UE performs location update and the mobility management network element changes, the target mobility management network element needs to request the original mobility management network element for the number of times the MTC UE has moved. Figure 5 It is a flowchart of an embodiment of the present invention, specifically including the following steps:

[0086] Step 501: When the MTC UE detects a new location area change, and the current location area identifier of the UE is not in the location column list of the UE registration network, the UE starts to trigger a location update procedure. The MTCUE sends a location update request to the target mobility management network element;

[0087] Step 502: the target mobility management network element sends a context request message to the original mobility managem...

Embodiment 3

[0095] In this embodiment, after the MTC UE is detached, the mobility management network element updates the number of times the MTC UE has moved in the user database. When the mobility management network element notifies the user database to delete the subscription data and mobility management context of the detached user, it needs to notify the user database to save the number of times the MTC UE has moved. Figure 6 It is a flowchart of an embodiment of the present invention, specifically including the following steps:

[0096] Step 601: After the mobility management network element deletes the subscription data and mobility management context of the deattached user, it sends a clear MTC UE message to the user database, which carries the number of times the MTC UE has moved;

[0097] Step 602: The user database marks the MTC UE as cleared, records the number of times the MTC UE has moved, and returns a clearing confirmation message to the mobility management network element...

Abstract

The invention discloses a method, device and system for limiting the moving times of machine type communication (MTC) equipment by a network. In the method, a mobility management network element is used for judging whether the MTC equipment moves or not; and if the MTC equipment moves, and the moving times of the MTC equipment exceeds the moving times permitted by a signed contact of the MTC equipment, the mobility management network element refuses the MTC equipment to access into a network. A complete solution for limiting the moving times of the MTC equipment by the network is provided, thus the moving times of the MTC equipment can be limited effectively.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and system for limiting the number of times a network moves an MTC device. Background technique [0002] figure 1 is a schematic diagram of an architecture of an evolved packet system (Evolved Packet System, referred to as EPS), such as figure 1 As shown, the EPS of the 3rd Generation Partnership Project (referred to as 3GPP) consists of an Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), a mobile management unit (Mobility Management Entity, MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW or PDN GW for short), Home Subscriber Server (Home Subscriber Server, HSS for short), Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short), Serving GPRS Supporting Node (SGSN for short) and other supporting nodes. Th...
