The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. Some embodiments, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention.

The architecture of M2M is shown in Figure 1. In Figure 1, AE and CSE communicate through X Reference Point (X Reference Point), and multiple CSEs communicate through Y Reference Point (Y Reference Point), while in CSE and NSE Through the Z reference point (Z Reference Point) communication, the above X, Y, and Ζ reference nodes are all communication program interfaces. In the prior art, the NSE stores information such as the amount of equipment that the CSE needs to acquire, the wireless signal quality of the device, and the current location of the terminal. However, in the prior art, the CSE cannot obtain the above information from the NSE through the reference node. Therefore, the present invention provides a method for enabling a CSE to obtain the above information from the NSE. As shown in FIG. 2, the method includes:

101. The NSE sends a list of information to the public service entity CSE, where the information list is at least a list of device information included in the NSE.

102. The CSE receives a list of information sent by the underlying network service entity, the NSE, where the information list is at least a list of device information included in the NSE.

The CSE sends the request information to the NSE according to the content in the information list, where the request information is used to request parameter information of the device, and the request information includes at least one device identifier.

104. The NSE receives the request information sent by the CSE.

105. The NSE obtains the device identifier in the request information, determines parameter information of the device corresponding to the sequence number, and sends the parameter information to the CSE.

106. The CSE receives parameter information corresponding to the device identifier sent by the NSE. An embodiment of the present invention provides a method for acquiring information, where the NSE sends a list including device information to the CSE, and the CSE sends the inclusion information to the NSE according to the received list. The request information of the identifier is such that the NSE sends the parameter information of the device corresponding to the sequence number in the request message to the CSE according to the received request information, so that the CSE finally receives the parameter information of the required device; thereby enabling the CSE to obtain the NSE from the NSE. The required information is obtained, and the acquired information can be processed to expand the application range of the machine communication. The present invention provides a method for information acquisition. As shown in FIG. 3, the method includes:

201. The CSE sends a request for the information list to the NSE. The request here may be only a request sent by signaling, and the request may not include any content, and the purpose is to enable the NSE to directly return a list of information to the CSE that sent the request after receiving the request.

202. After receiving the CSE request, the NSE sends a message list to the CSE. Specifically, the information list may include information about the type and serial number of the terminal device, the terminal identifier, the terminal power, the terminal location, the attachment activation time, and the QoS. The above information is stored in the NSE as information about the terminal device.

203. The CSE receives and saves a list of information sent by the NSE.

The reason why the CSE saves the list of information provided by the NSE is that the CSE or Application Entity (AE) sends the request information to the NSE again, and does not need to send the request for the information list to the NSE again, thereby saving time and Steps, the effect of improving efficiency.

204. The CSE sends the request information to the NSE according to the received information and the actual requirement. The request information is used to request parameter information of the device, and the request information includes at least one device identifier (specifically, one of IMSI, external ID, IMEI, etc. is used for device identification). When the CSE requests the parameter information of multiple devices, the request information sent to the NSE includes the identification information corresponding to the multiple devices. In the request information, in addition to the serial number corresponding to the device, specific time information corresponding to the parameter information may be included, so that the NSE returns to the specific time and The parameter information of the device corresponding to the serial number. The device identifier is included in the sent request information, so that the NSE can obtain the information required by the CSE through the serial number in the content stored by the NSE; especially when the request information of the CSE includes multiple devices. When the serial number is obtained, the NSE can quickly obtain information corresponding to multiple devices.

205. The NSE receives the request information sent by the CSE.

206. The NSE obtains the device identifier in the request information, and determines parameter information corresponding to the device identifier, and then sends the parameter information corresponding to the device identifier to the CSE.

207. The CSE receives the parameter information corresponding to the device identifier sent by the NSE. It is worth mentioning that the actual requirements in step 205 specifically include two cases: When the parameter information in the request information sent by the CSE is requested by the AE, at the beginning of the method, the AE also sends a parameter information request to the NSE. The steps, and correspondingly, after the CSE obtains the parameter information from the NSE, the CSE also sends the parameter information to the AE step.

When the parameter information in the request information sent by the CSE is not requested by the AE, after the CSE obtains the parameter information from the NSE, the CSE also sends the parameter information to the AE or a third-party analysis tool, so as to perform the parameter information in the next step. Processing. The above two results are caused by the fact that the subject of the information request is initiated and the subsequent processing of the parameter information received by the CSE is different. When the subject of the information request is AF, the AF first sends a request to the CSE, and correspondingly, the CSE needs to send the acquired parameter information to the AF at the end of the method. When the subject of the information request is not AF, then at the end of the method, the CSE also needs to send the received parameter information information to AF or other third party tools for further processing or analysis. The embodiment of the present invention provides a method for acquiring information, where the CSE sends a request for the information list to the NSE, and receives a list of information that the NSE can provide, and then the CSE combines the received information with the NSE to provide a list of information that can be provided to the NSE. Sending the request information carrying the device identifier, so that the NSE receives the request information sent by the CSE. After obtaining the device identifier in the request information, and determining the parameter information corresponding to the sequence number, and then sending the parameter information corresponding to the sequence number to the CSE, so that the CSE performs the subsequent steps according to the body that sends the request; thereby enabling the CSE to The NSE obtains the required information, which in turn can process the acquired information and expand the application range of the machine communication. The embodiment of the present invention further provides another method for information acquisition. As shown in FIG. 4, the method includes:

301. The CSE sends a request message carrying the device identifier to the NSE according to the stored information list.

302. The NSE determines parameter information of the device corresponding to the sequence number according to the device identifier in the request information.

303. The NSE sends the parameter information corresponding to the serial number to the CSE.

304. The CSE receives the parameter information corresponding to the device identifier sent by the NSE and saves the parameter information. The subsequent processing method of the received and saved parameter information is the same as step 20X in the previous embodiment, and details are not described herein again. In this method, the reason why the CSE does not obtain the information list that the NSE can provide from the NSE before the step 301 is because the information list that the NSE can provide has been notified by direct transmission or pre-storage before the method is performed. The CSE is configured to enable the CSE to obtain a list of information that the NSE can provide, and then directly send the request information carrying the device serial number to the NSE, and receive the parameter information of the device provided by the NSE according to the request information from the NSE, so that the CSE can Get the information you need from the NSE. The present invention provides a method for information acquisition. The CSE sends request information with a device identifier to the NSE according to the built-in information list, and obtains the required parameter information from the NSE and saves it; thereby enabling the CSE to be obtained from the NSE. The required information, in turn, can process the acquired information and expand the application range of machine communication.

401. The CSE sends a request information with a device identifier to the NSE.

402. The NSE determines parameter information corresponding to the device identifier according to the device identifier in the request information.

403. The NSE sends the determined parameter information to the CSE.

404. The CSE receives the parameter information sent by the NSE. In the method, the CSE sends the request information that only carries the device identifier to the NSE, and the NSE provides the stored parameter information corresponding to the device identifier to the CSE according to the device identifier in the received request information. Since the NSE does not send the stored information list to the CSE, the NSE may not provide the parameter information corresponding to all the device identifiers in the request information for the received CSE including the device identification request information. Next, the NSE only needs to send the parameter information of the corresponding device identifier that it can provide to the CSE. The embodiment of the present invention provides a method for acquiring information, and the CSE sends the request information with the device identifier to the NSE, so that after receiving the request information, the NSE determines the parameter information corresponding to the device identifier in the request message, and The determined parameter information is sent to the CSE; thus, the CSE can obtain the required information from the NSE, and then the acquired information can be processed to expand the application range of the machine communication.
