When the MTC terminal leaves the attach state, the MTC application server records related information of the MTC terminal, and passes the The MTC terminal is paged in a long-period paging manner within a certain geographical range; as shown in FIG. 1, the method includes the following steps:

Step 101: When the MTC terminal leaves the attach state, the core network device sends the location information of the MTC terminal and the paging configuration information to the MTC application server.

In the embodiment of the present invention, the location information (that is, the geographic location information when the MTC terminal leaves the attach state) includes but is not limited to one or any combination of the following: latitude and longitude information, TA (Tracking Area) information, RA (Transition Area) , routing area) information, LA (Location Area) information, ECGI (E-UTRAN Global Cell ID, global cell identity of the evolved wireless access system) information; the paging configuration information includes but is not limited to one of the following or Any combination: paging time information, paging period information, paging location information, and paging effective time period information.

In the embodiment of the present invention, the location information and the paging configuration information of the MTC terminal may be directly obtained by the core network device (such as an MME (Mobility Management Entity), etc.), or may be an access network device (such as a base station device). The location information of the MTC terminal and the paging configuration information are obtained, and the location information of the MTC terminal and the paging configuration information are notified to the core network device.

For the process of obtaining the location information and the paging configuration information by the access network device, the MTC terminal is: when the MTC terminal leaves the attach state (that is, the MTC terminal decides to leave the attach state without the content to interact with the MTC server for a certain period of time), the MTC terminal Will need it The information to leave the attach state is notified to the access network device, and the access network device receives the information from the MTC terminal that needs to leave the attach state, and obtains the location information of the MTC terminal and the paging configuration information, and the location of the MTC terminal.

It is to be noted that, after obtaining the paging configuration information of the MTC terminal, the access network device or the core network device also needs to notify the MTC terminal of the paging configuration information, and the MTC terminal monitors the subsequent use of the paging configuration information. Paging process.

Further, after receiving the paging configuration information, the NAS (Non Access Layer) layer is in a state of leaving the attach, and after leaving the attach state, the access layer module of the MTC terminal (such as physics) The layer module, the MAC (Medium Access Control) layer module, and the RRC (Radio Resource Control) layer module are activated, and are determined according to the paging cycle (determined by the paging configuration information, and the existing Compared with the technology, it takes longer to perform paging monitoring, and other modules of the MTC terminal (such as the NAS layer module and the upper application module) are in an inactive state; further, the access layer module of the MTC terminal is listening for After the call, other modules of the MTC terminal need to be activated, and the access process is performed, and data or signaling interaction with the network side (ie, the access network device and/or the core network device) is performed.

Step 102: The MTC application server receives location information and paging configuration information of the MTC terminal from the core network device, and saves the location information and the paging configuration information of the MTC terminal.

Step 103: When the MTC application server needs to page the MTC terminal, the MTC application server sends the location information of the MTC terminal and the paging configuration information to the core network device. Ready.

In the embodiment of the present invention, after the location information of the MTC terminal and the paging configuration information are saved, the MTC application server needs to identify that the state of the MTC terminal is offline. Further, when the MTC application server needs to page the MTC terminal, If it is determined that the state of the MTC terminal is offline, the location information of the MTC terminal and the paging configuration information are sent to the core network device to request the core network device to page the MTC terminal.

Step 104: The core network device receives location information and paging configuration information of the MTC terminal from the MTC application server, where the location information and the paging configuration information may be carried in a request for paging the MTC terminal, and the core network device is receiving After the request to page the MTC terminal, it is determined that the MTC terminal needs to be paged, that is, the subsequent steps are performed.

Step 105: The core network device determines the paging range by using the location information, and uses the paging configuration information to page the MTC terminal within the paging range.

It should be noted that, in the embodiment of the present invention, the paging range may be specifically: one cell or multiple cells, and the multiple cells are cells controlled by a core network device or cells controlled by multiple core network devices. And the cell under the control of the multiple core network devices is a same coverage cell or multiple inter-frequency cells under control of multiple core network devices.

Unique paging identifier (allocated unique paging identifier in the network that is permanently used).

In the embodiment of the present invention, after the MTC terminal leaves the attach state, the core network device also needs to delete the context information of the MTC terminal, and the paging identifier of the frozen MTC terminal cannot be allocated to other MTC terminals.

In summary, since many MTC terminals are fixed in position and do not need to communicate for a relatively long time, if the MTC terminal can be turned off for a long time, a large amount of power can be saved. Therefore, it is desirable to temporarily disable the radio frequency and other power-consuming entities for the MTC terminal that does not communicate for a long time. In the prior art, if the MTC terminal is in the non-attach state, the MTC terminal cannot obtain the network information, and the network triggers the MTC terminal to enter the connection state for communication; in the embodiment of the present invention, the MTC terminal is saved by using the MTC application server. Paging configuration information To achieve the purpose of power saving, by storing paging configuration information on the MTC application server and allowing a longer period of paging occasions to be configured, the MTC terminal can be better saved.

In addition, the location information of the MTC terminal and the paging configuration information are sent to the MTC application server through the core network device, which can reduce the air interface signaling load compared with the existing method.

In addition, in the prior art, if the network configuration is changed, for example, an MME is deactivated, the S-TMSI allocated by the MME cannot be used to page the MTC terminal. In the embodiment of the present invention, the entire network is uniquely identified. As the paging identifier of the MTC terminal, the network can perform paging in a more suitable area, and avoid the situation that the MME changes and the S-TMSI fails and cannot be paged.

The embodiments of the present invention are described in detail below in conjunction with specific application scenarios.
