Problems solved by technology

However, the paging process in the prior art cannot meet such requirements
Even if the MTC server or MTC user provides the preset area information of the MTC terminal to the cell broadcast center to broadcast and wake up the offline MTC terminal, there are still disadvantages such as not being able to find the mobile terminal and requiring the network operator to set up a cell broadcast center.

Embodiment 1

[0087] Figure 5 When the MTC terminal is deattached, the mobility management unit transmits signaling to the MTC server through the direct connection interface, and sends the latest location information of the MTC terminal and the identity of the MTC terminal to the MTC server for storage. After the MTC terminal is offline, the MTC server The process of triggering the mobility management unit to page the MTC terminal and finally activate the MTC terminal. Such as Figure 5 shown, including the following steps:

[0088] Step 501, the MTC terminal in the registered state initiates a detach process, or the network initiates an explicit detach process, or the network initiates an implicit detach process;

[0089] According to different network configurations, the mobility management unit will delete the context information of the terminal or mark it as invalid after a period of time or immediately.

[0090] The MTC terminal will enter the offline / unregistered state afterwards....

Embodiment 2

[0103] Figure 6 When the location update of the MTC terminal fails, the mobility management unit transmits signaling to the MTC server through the direct connection interface, and sends the latest location information and terminal identity of the MTC terminal to the MTC server for storage. After the MTC terminal goes offline, the MTC server Trigger the process of the mobility management unit paging the MTC terminal and activating the MTC terminal. Such as Figure 6 shown, including the following steps:

[0104] Step 601, the MTC terminal moves to a new location and uses its identity to initiate a location update process, but the process fails;

[0105] After the update procedure fails, the current mobility management unit marks the context of the MTC terminal as detached. According to the network configuration, the mobility management unit will delete the context or mark it as invalid after a period of time or immediately. The MTC terminal will then enter the offline / unreg...

Embodiment 3

[0108] Figure 7 It is to transmit signaling between the mobility management unit and the MTC server through the direct connection interface when the MTC terminal fails to attach, and send the latest location information and identity of the MTC terminal to the MTC server for storage, and after the MTC terminal goes offline, the The MTC server triggers the process of the mobility management unit paging the MTC terminal and activating the MTC terminal. Such as Figure 7 shown, including the following steps:

[0109] Step 701, the offline MTC terminal fails to initiate the attach process;

[0110] The MTC terminal in the offline state initiates the attach process, but the mobility management unit does not receive the attach completion message returned by the MTC terminal after trying to resend the attach accept message, and the MTC terminal does not respond when it tries to page the MTC terminal. The mobility management unit will The context of the MTC terminal is marked as de...

Abstract

A method and system for activating a terminal are provided by the present invention. The method includes: when the situation of triggering a Machine Type Communication (MTC) terminal (1) offline occurs, a Mobility Management Entity (MME) (3) sends the identity of the MTC terminal (1) to an MTC server (6) or an intermediate network element, before deleting or marking invalid the context information of the MTC terminal (1); the MTC server (6) or the intermediate network element receives and stores the identity of the MTC terminal (1); when the MTC server (6) needs to activate the MTC terminal (1), the MTC server (6) sends, directly or via the intermediate network element, the offline activation message carrying the identity of the MTC terminal (1) to the MME (3); the MME (3) receives the offline activation message and initiates paging the MTC terminal (1) according to the identity of the MTC terminal (1); the MTC terminal (1) stores the received paging identity under the offline situation, and monitors the broadcast channel of the cell which it is located in, thus responding to the paging and realizing offline activation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for activating an offline terminal and a machine type communication terminal. Background technique [0002] In order to maintain the competitiveness of the third generation mobile communication system in the communication field, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) standard working group is working on the research of EPS (Evolved Packet System, Evolved Packet Domain System). The whole EPS system such as figure 1 The shown mainly includes two parts: E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) and EPC (Evolved Packet Core, Evolved Packet Core Network). The EPC of the system can support user access from GERAN (GSM EDGE radioaccess network, GSM EDGE wireless access network) and UTRAN (Universal Terrestrial Radio Access Network, universa...
