In order to better understand the technical solution of the present invention, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a method for obtaining a paging area according to an embodiment of the present invention.
In the embodiment of the present invention, the MTC device may be deployed in a mobile communication network by an MTC service provider (MTC Subscriber), and a MTC Server (MTC Server) may manage the MTC device, and the MTC Server may use a Global Positioning System (GPS) technology to obtain a geographic location of the deployed MTC device. The method for obtaining the paging area provided by the first embodiment of the invention mainly comprises the following steps:
a1, receiving a geographical position reporting message of the MTC device sent by the MTC server, wherein the geographical position reporting message carries geographical position information of the MTC device and an identifier of the MTC device.
Specifically, a network device in the mobile communication network may receive a geographic location report message sent by the MTC server, where the report message carries geographic location information of the MTC device and an identifier of the MTC device. The network device may be an Operation Support System (OSS) or other devices.
The geographical location information of the MTC device may be a longitude and latitude of the MTC device, and the identifier of the MTC device may be an International Mobile Equipment Identity (IMEI) and/or an International Mobile Subscriber Identity (IMSI) of the MTC device.
In addition, the communication interface between the MTC server and the network device and the transmission format of the geographical location reporting message may be flexibly set by an operator.
And A2, acquiring network location information corresponding to the geographical location information according to the preset mapping between the geographical location area and the network location area.
Specifically, the network device may preset mapping between a geographical location area and a network location area according to a coverage area of the mobile communication network, and further obtain network location information corresponding to the geographical location information according to the mapping.
The network location information acquired by the network device includes a cell identifier of a cell where the MTC device is located. Since the MTC device may be located in an area where two or more cells overlap, the network location information includes two or more network locations, that is, may include multiple cell identifiers.
And A3, sending the identification of the MTC equipment and the network location information to a home location register or a home subscriber server.
Specifically, after obtaining the network location information corresponding to the address location information of the MTC device, the network device sends the network location information of the MTC device and the identifier of the MTC device to a home location register or a home subscriber server in the mobile communication network.
The network device may send the network location information and the identifier to the HLR or the HSS through an S6d interface, and transmit the network location information and the identifier using a Mobile Application Part (MAP) General Packet Radio Service (GPRS) location (update) message. The embodiment of the invention can enhance the MAP _ UPDATE _ GPRS _ LOCATION message and add parameters of CGI/ECGI List, RAI/TAI List, MTC IMSI List and MTCIMEISV List. The "CGI/ECGI List" parameter may store a global cell identity where the MTC device is located, the "RAI/TAI List" parameter may store a routing area identity and/or a tracking area identity where the MTC device is located, the "MTC IMSI List" parameter may store an IMSI of the MTC device, and the "MTCIMEISV List" parameter may store an IMEI of the MTC device.
In the embodiment of the invention, the network equipment acquires the network location information corresponding to the geographical location information of the MTC equipment according to the mapping between the preset geographical location area and the network location area, then the network location information and the identifier of the MTC equipment are sent to the home location register or the home subscriber server, and the home location register or the home subscriber server can acquire the paging area of the MTC equipment according to the received network location information. Compared with the prior art, the embodiment of the invention can enable the HLR or HSS to obtain the paging area of the low-mobility equipment, and then page the MTC equipment according to the paging area, thereby saving network signaling resources and improving the paging efficiency.
Further, if the operator of the mobile communication network reconfigures the network, the coverage area of the cell in the network changes, and the network device needs to obtain the network location information of the MTC device again at this time. The embodiment of the invention can further execute the following steps:
a4, receiving a network updating message, wherein the location updating message carries indication information for updating network location information.
Specifically, the mobile communication network may send a network update message to the network device, the network device may receive the network update message, where the network update message carries indication information for updating the network location information, and the network device then performs step a 5.
And A5, updating the mapping between the geographical location area and the network location area according to the indication information.
Specifically, the network device may update the mapping between the preset geographical location area and the network location area according to the indication information sent by the mobile communication network.
When the network device updates the mapping, the mapping of all the geographical location areas does not need to be updated, and only the mapping of the geographical location area with changed network coverage needs to be updated.
Furthermore, the mobile communication network may actively update the mapping between the geographical location area and the network location area after the cell coverage has changed, and then send the updated mapping between the geographical location area and the network location area to the network device.
And A6, obtaining the updated network location information corresponding to the geographical location information according to the mapping between the updated geographical location area and the network location area.
Specifically, the network device obtains updated network location information corresponding to the geographical location information of the MTC device according to the mapping between the updated geographical location area and the network location area.
And A7, sending the identification of the MTC equipment and the updated network location information to a home location register or a home subscriber server.
Specifically, after obtaining the network location information corresponding to the address location information of the MTC device, the network device sends the identifier of the MTC device and the updated network location information to a home location register or a home subscriber server in the mobile communication network. It should be noted that the main network device for executing the steps a1-a7 is not limited to the operation support system, and may be other devices.
The embodiment of the invention can be used in an application scene that the cell coverage of a mobile communication network is changed, can flexibly obtain the paging area of the MTC equipment and has wider application range.
In the embodiment of the present invention, the MTC devices include the following three types:

The Cell Identifier may be a Global Cell Identifier (CGI) or an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Global Cell Identifier.
2) And if the type information indicates that the MTC equipment is not the third type MTC equipment, acquiring a cell identifier corresponding to the geographical location information according to mapping between a preset geographical location area and a network location area.
Since the non-third-type MTC device (the first-type MTC device or the second-type MTC device) may not move within a large range, the network location information obtained by the network device may only include the cell identifier where the MTC device is located. The Cell Identifier may be a Global Cell Identifier (CGI) or an Evolved Universal Terrestrial radio access Network (E-UTRAN) Global Cell Identifier.
In the embodiment of the invention, the cell identifier is acquired aiming at the MTC equipment with low mobility, and the cell identifier and the routing area identifier and/or the tracking area identifier are acquired aiming at the MTC equipment with high mobility, so that the network position information can be acquired quickly, and the efficiency of acquiring the paging area is further improved.
Further, after acquiring the cell identifier, the routing area identifier, and/or the tracking area identifier corresponding to the geographic location information of the third type of MTC device according to the mapping between the preset geographic location area and the network location area, the network device may further send the identifier of the third type of MTC device, the cell identifier, the routing area identifier, and/or the tracking area identifier of the third type of MTC device to the MTC server, so that the MTC server may send the network location information of the third type of MTC device to the corresponding third type of MTC device.
