Embodiment 1

[0125] In this embodiment, the implementation process of the terminal that has been attached to the network transitioning to the offline state is described in detail.

[0126] Specifically, in this embodiment, a terminal that has been attached to the network is implicitly converted to an offline state. Refer to Figure 4 As shown, including the following steps:

[0127] Step 401: After the MTC device attaches and enters the IDLE state, the MTC device and the MME simultaneously start the same second timer.

[0128] Here, the same second timer is set in the MTC device and the MME in advance.

[0129] Step 402: Until the second timer expires, the MTC device does not initiate a service request, the MTC device and the MME respectively change the state of the MTC device to an offline state, and the MME deletes the bearer information related to the MTC device saved by itself , Save the location information and status information of the MTC device.

[0130] Here, the subscription information o...

Embodiment 2

[0137] In this embodiment, the terminal that has been attached to the network is converted to the offline state by display mode, refer to Figure 5 As shown, including the following steps:

[0138] Step 501: The MME sends a detach accept message to the MTC device, where the detach accept message carries parameters indicating the transition to an offline state.

[0139] Step 502: After receiving the detach accept message, the MTC device converts its own state to an offline state, and saves its own location information and state information; after sending the detach accept message, the MME records the information recorded by itself The state of the MTC device is set to an offline state, and the saved bearer information related to the MTC device is deleted, and the location information and status information of the MTC device are saved;

[0140] Step 503: MME notifies S-GW and P-GW to delete all information related to the MTC device;

[0141] Step 504: The MME sends a notification messag...

Embodiment 3

[0145] Reference Image 6 As shown, in this embodiment, when the location of the MTC device changes, the MME serving the MTC device does not change. The specific process of mobility management of the terminal in the offline state includes the following steps:

[0146] Step 601: The MTC device periodically monitors the broadcast channel of the current network and finds that its location has changed.

[0147] Specifically, the MTC device periodically monitors the network broadcast channel, obtains its current location information, and compares the obtained current location information with the location information saved by the MTC device. When the saved location information is different, it indicates that the location of the MTC device has changed.

[0148] Step 602: The MTC device sends a location re-registration request to the MME.

[0149] Here, the location re-registration request carries current location information of the MTC device.

[0150] Step 603: After the MME on the network ...

Abstract

The invention discloses a mobility management method of a terminal in an offline state. The method comprises: a terminal in an offline state obtains location information of its current location; according to the obtained location information, the terminal finds its own location When changing, initiate location re-registration to the network side; the network side updates the saved location information of the terminal. The present invention also discloses a terminal mobility management system in the offline state. In addition, the present invention also discloses a terminal triggering method and system in the offline state, which can realize the mobility management and management of the terminal when the terminal is in the offline state. trigger.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for terminal mobility management or triggering in an offline state. Background technique [0002] With the development of mobile network services and automation control technology, a machine-type communication (MTC) method has emerged, called the machine-to-machine (M2M) communication method. In this communication method, at least One party is machinery and equipment. [0003] The narrow definition of M2M is machine-to-machine communication. Broadly speaking, M2M includes networked applications and services centered on the intelligent interaction of machine terminals. M2M is based on intelligent machine terminals and uses multiple communication methods as access means. It can provide customers with informatization solutions to meet customers' informatization needs for monitoring, command and dispatch, data collection and measurement. M2M can be applied t...
