After receiving the target data reported by the base station 104, the AIMF 106 may update the terminal collection information of the passive IoT terminal 102 according to the target data.

[0165] In an exemplary embodiment, the terminal collection information may include at least one of the identification information of the base station bound to the passive IoT terminal, the storage data of the passive IoT terminal, the state information of the passive IoT terminal, the location information of the passive IoT terminal, and the collection information update time of the passive IoT terminal. The state information of the passive IoT terminal may include a normal state and an abnormal state, etc., wherein the abnormal state may include a lost / damaged state.

[0166] The management system of passive Internet of Things terminals provided by the embodiments of the present disclosure includes at least one passive Internet of Things terminal, at least one base station, and an integrated passive Internet of Things management function module AIMF, wherein AIMF is integrated in the access and mobility management module AMF, wherein AIMF can periodically send a request for reporting data, and after receiving the request for reporting data, the base station broadcasts the request for reporting data within the coverage area, and after the passive Internet of Things terminal receives the request for reporting data broadcast by the base station, it can feedback terminal data to the base station according to the request for reporting data, and after the base station receives the terminal data of the passive Internet of Things terminal, it can report target data to AIMF according to the terminal data of the passive Internet of Things terminal, and after AIMF receives the target data, it can update the terminal collection information of the passive Internet of Things terminal according to the target data. Based on the management system of passive Internet of Things terminals provided by the embodiments of the present disclosure, a solution for network access and mobile management of passive Internet of Things terminals that are not equipped with SIM cards and do not have the ability to independently access the 3GPP core network can be provided, thereby improving the efficiency of network access and mobile management of passive Internet of Things terminals, and since AIMF is integrated in AMF, it can reduce deployment costs.

[0167] In an exemplary embodiment, the AIMF 106 is further configured to update the information update time of the passive IoT terminal 102 and update the status information of the passive IoT terminal to an abnormal state when the target data corresponding to the passive IoT terminal 102 is not received.

[0168] In the disclosed embodiment, after AIMF106 issues a request to report data, for any passive Internet of Things terminal, if the base station does not feedback the target data for the passive Internet of Things terminal within the specified time, or the target data received from the base station feedback does not carry the terminal data of the passive Internet of Things terminal, that is, AIMF does not receive the terminal data of the passive Internet of Things terminal, it can be determined that the passive Internet of Things terminal is currently in an abnormal state, so the status information of the passive Internet of Things terminal can be updated to an abnormal state, and based on the time for updating the status information of the passive Internet of Things terminal, the information update time of the passive Internet of Things terminal is updated.

[0169] In an exemplary embodiment, AIMF 106 is further configured to, upon receiving target data corresponding to the passive IoT terminal 102, update the status information of the passive IoT terminal to a normal state if the status information of the passive IoT terminal is in an abnormal state.

[0170] In the disclosed embodiment, when the target data received by AIMF106 carries the terminal data of the passive Internet of Things terminal 102, it can be determined that the state of the passive Internet of Things terminal is normal. At this time, if the state information of the passive Internet of Things terminal is recorded as an abnormal state, it can be determined that the passive Internet of Things terminal has returned to normal, and the state information of the passive Internet of Things terminal can be updated from the abnormal state to the normal state.

[0171] In an exemplary embodiment, AIMF106 is also used to, when receiving multiple target data corresponding to the passive Internet of Things terminal, if there is target data fed back by the base station bound to the passive Internet of Things terminal, not update the identification information of the base station bound to the passive Internet of Things terminal.

[0172] In the disclosed embodiment, when the passive IoT terminal is in the overlapping area of ​​multiple base stations, multiple target data will be fed back to AIMF106 through the multiple base stations. For example: the passive IoT terminal is at position A. Since position A is both within the coverage of base station 1 and base station 2, the passive IoT terminal will respond to the data reporting request broadcast by base station 1 to feed back the terminal data of the passive IoT terminal to base station 1, and will also respond to the data reporting request broadcast by base station 2 to feed back the terminal data of the passive IoT terminal to base station 2. Then, base station 1 and base station 2 will feed back the target data to AIMF106 based on the terminal data of the passive IoT terminal.

[0173] When the multiple target data fed back by multiple base stations received by AIMF106 all carry the terminal data of the same passive Internet of Things terminal, AIMF106 can determine the base station to which the passive Internet of Things terminal is currently bound as recorded locally. If the multiple target data received contain the target data fed back by the base station to which the passive Internet of Things terminal is currently bound, the identification information of the base station to which the passive Internet of Things terminal is bound will not be updated. Exemplarily, still taking the above example, assuming that the base station to which the passive Internet of Things terminal is currently bound is base station 1, and the multiple target data received at this time include the target data sent by base station 1, the identification information of the base station to which the passive Internet of Things terminal is bound will not be updated, that is, the identification information of the base station to which the passive Internet of Things terminal is bound will still be the identification information of base station 1.

[0174] In an exemplary embodiment, AIMF106 is also used to, when receiving multiple target data corresponding to the passive Internet of Things terminal, if there is no target data fed back by the base station bound to the passive Internet of Things terminal, update the identification information of the base station bound to the passive Internet of Things terminal according to the base station that feeds back the target data and is closest to the base station bound to the passive Internet of Things terminal.

[0175] In the disclosed embodiment, if the target data fed back by the base station to which the passive IoT terminal is currently bound does not exist in the received multiple target data, it can be determined that the passive IoT terminal has currently left the bound base station, that is, unbound from the base station. Then, the base station closest to the base station to which the passive IoT terminal is bound can be determined from the base stations that feed back the multiple target data, and the base station is determined as the base station to which the passive IoT terminal is currently bound, and the identification information of the base station to which the passive IoT terminal is bound is updated to the identification information of the base station.

[0176] Exemplarily, assuming that the base station currently bound to the passive Internet of Things terminal is base station 3, the target data received from base station 1 and base station 2 at this time carries the terminal data of the passive Internet of Things terminal, that is, the target data sent by base station 3 for the passive Internet of Things terminal is not received. It can be determined that the passive Internet of Things terminal is currently unbound from base station 3, and the base station closest to base station 3 is determined from base station 1 and base station 2. Assuming that base station 1 is closer to base station 3, it can be determined that the base station currently bound to the passive Internet of Things terminal is not base station 1, and the identification information of the base station bound to the passive Internet of Things terminal is updated, that is, the identification information of the base station bound to the passive Internet of Things terminal is updated from the identification information of base station 3 to the identification information of base station 1.

[0177] In an exemplary embodiment, the system may further include NEF108 (Network Exposure Function, network capability exposure module), wherein:

[0178] NEF108 is used to forward the terminal data acquisition request sent by AF (Application Function) to AIMF106; AIMF106 is also used to receive the terminal data acquisition request, and send the target terminal acquisition information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request in the locally stored terminal acquisition information to NEF108; NEF108 is also used to forward the target terminal acquisition information to AF.

[0179] In the disclosed embodiment, when AF sends a terminal data acquisition request to NEF108, NEF108 may forward the terminal data acquisition request to AIMF106, wherein the terminal data acquisition request is used to indicate the acquisition of terminal data within a specified range, for example: terminal data of a specified terminal and / or a specified data type and / or a specified data update time. After receiving the terminal data acquisition request, AIMF106 may respond to the terminal data acquisition request and obtain target terminal acquisition information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request from the terminal acquisition information stored locally, wherein when the terminal acquisition information corresponding to the specified terminal and / or the specified data type is stored locally, it may be determined that there is terminal acquisition information that hits the terminal data acquisition request, and when the update time of the terminal acquisition information meets the data update time, it may be determined that the timeliness requirement of the terminal data acquisition request is met.

[0180] When the target terminal collection information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request is obtained from the locally stored terminal collection information, AIMF 106 may send the target terminal collection information to NEF 108 , and NEF 108 forwards the target terminal collection information to AF.

[0181] In an exemplary embodiment, AIMF 106 is further configured to:

[0182] When there is no target terminal collection information that hits the terminal data acquisition request and / or there is no target terminal collection information that meets the timeliness requirements of the terminal data acquisition request in the locally stored terminal collection information, a data reporting request is sent; the target data fed back by the base station 104 is received, and the terminal collection information of the passive Internet of Things terminal is updated according to the target data; the target terminal collection information that hits the terminal data acquisition request in the locally stored terminal collection information is sent to the NEF.

[0183] In the disclosed embodiment, when there is no target terminal collection information that hits the terminal data acquisition request and / or there is no target terminal collection information that meets the timeliness requirements of the terminal data acquisition request in the terminal collection information locally stored by the AIMF, in order to meet the functional requirements of the AF, a data reporting request can be sent, so that the base station 104 that receives the data reporting request can broadcast the data reporting request within the coverage area, so that the passive Internet of Things terminal 102 that receives the data reporting request can feedback the terminal data to the base station 104, and the base station 104 further sends the target data to the AIMF 106 according to the terminal data fed back by the passive Internet of Things terminal 102. The AIMF 106 updates the locally stored terminal collection information based on the target data sent by the base station 104, and determines from the updated terminal collection information whether there is target terminal collection information that hits the terminal data acquisition request. If so, the target terminal collection information is sent to the NEF 108, and the NEF 108 forwards the target terminal collection information to the AF.

[0184] In one embodiment, Figure 2 As shown, a management method for a passive Internet of Things terminal is provided, and the method is applied to Figure 1 Taking the integrated passive Internet of Things management function module AIMF in the example as an example, the following steps are included:

[0185] Step 202, periodically sending a request for reporting data, so that a base station receiving the request for reporting data broadcasts the request for reporting data within a coverage area;

[0186] Step 204: receiving target data reported by the base station, and updating the terminal collection information of the passive Internet of Things terminal according to the target data.

[0187] Among them, the target data is the data reported to the AIMF by the base station according to the terminal data after receiving the terminal data reported by the passive IoT terminal, and the terminal data is the data fed back to the base station after the passive IoT terminal receives the request to report data.

[0188] In the disclosed embodiment, AIMF may periodically send a data reporting request to the base station, so that the base station receiving the data reporting request broadcasts the data reporting request within the coverage area. When a passive Internet of Things terminal located within the coverage area of ​​the base station receives the data reporting request, it may respond to the data reporting request and send terminal data to the base station. The base station further sends target data to AIMF based on the terminal data fed back by the terminal and its own base station identification. In an exemplary embodiment, the target data may include the identification information of the base station and the terminal data.

[0189] After AIMF receives the target data, it can update the terminal collection information of the passive Internet of Things terminal according to the time of receiving the target data, the terminal data carried in the target data, and the identifier of the base station. The specific process can be referred to the relevant description of the aforementioned embodiment, which will not be repeated in the embodiments of the present disclosure.

[0190] In the management method of passive IoT terminals provided by the embodiments of the present disclosure, AIMF can periodically send a request for reporting data, so that the base station receiving the request for reporting data broadcasts the request for reporting data within the coverage area; receives the target data reported by the base station, and updates the terminal collection information of the passive IoT terminal according to the target data. Based on the management method of passive IoT terminals provided by the embodiments of the present disclosure, a solution for network access and mobile management of passive IoT terminals that are not equipped with SIM cards and do not have the ability to independently access the 3GPP core network can be provided, thereby improving the efficiency of network access and mobile management of passive IoT terminals.

[0191] In an exemplary embodiment, the terminal data includes identification information of the passive Internet of Things terminal and storage data of the passive Internet of Things terminal; or, the terminal data includes identification information of the passive Internet of Things terminal, storage data of the passive Internet of Things terminal and location information of the passive Internet of Things terminal.

[0192] By adopting the management method of the passive Internet of Things terminal provided by the embodiment of the present disclosure, the passive Internet of Things terminal can periodically report terminal data such as identification information, storage information and location information to the AIMF through the base station, so that the AIMF can implement network access and mobility management for the passive Internet of Things terminal based on the above terminal data of the passive Internet of Things terminal.

[0193] In an exemplary embodiment, the terminal collection information includes at least one of the identification information of the base station to which the passive Internet of Things terminal is bound, the storage data of the passive Internet of Things terminal, the status information of the passive Internet of Things terminal, the location information of the passive Internet of Things terminal, and the collection information update time of the passive Internet of Things terminal.

[0194] In the disclosed embodiment, AMIF can determine the passive Internet of Things terminal based on the identification information of the passive Internet of Things terminal carried in the target data, and use the base station represented by the identification information of the base station carried in the target data as the base station bound to the passive Internet of Things terminal represented by the identification information of the passive Internet of Things terminal. Therefore, based on the identification information of the base station carried in the target data, the identification information of the base station bound to the passive Internet of Things terminal can be updated locally; and the storage data of the passive Internet of Things terminal stored locally can be updated according to the storage data of the passive Internet of Things terminal carried in the target data.

[0195] AIMF can update the location information of the passive Internet of Things terminal stored locally according to the location information of the passive Internet of Things terminal carried in the target data. When the location information of the passive Internet of Things terminal is not carried in the target data, the passive Internet of Things terminal can be located through network devices such as base stations to obtain the location information of the passive Internet of Things terminal, and the location information of the passive Internet of Things terminal stored locally is updated according to the location information. The positioning method is not specifically limited in the embodiments of the present disclosure.

[0196] The status information of the passive IoT terminal may include normal status and abnormal status, etc., wherein the abnormal status may include lost / damaged status, etc. The AIMF may determine the status information of the passive IoT terminal based on the target data, and update the status information of the passive IoT terminal stored locally.

[0197] By adopting the management method of the passive Internet of Things terminal provided by the embodiment of the present disclosure, the AIMF can realize network access and mobility management for the passive Internet of Things terminal based on the terminal data fed back by the passive Internet of Things terminal through the base station.

[0198] In an exemplary embodiment, the above method may further include:

[0199] If the target data corresponding to the passive Internet of Things terminal is not received, the information update time of the passive Internet of Things terminal is updated, and the status information of the passive Internet of Things terminal is updated to an abnormal state.

[0200] In the disclosed embodiment, after AIMF issues a request to report data, for any passive Internet of Things terminal, if the base station does not feedback the target data for the passive Internet of Things terminal within the specified time, or the target data received from the base station feedback does not carry the terminal data of the passive Internet of Things terminal, that is, AIMF does not receive the terminal data of the passive Internet of Things terminal, it can be determined that the passive Internet of Things terminal is currently in an abnormal state, so the status information of the passive Internet of Things terminal can be updated to an abnormal state, and based on the time for updating the status information of the passive Internet of Things terminal, the information update time of the passive Internet of Things terminal is updated.

[0201] In an exemplary embodiment, updating the terminal collection information of the passive Internet of Things terminal according to the target data may include:

[0202] If the status information of the passive Internet of Things terminal is in an abnormal state, the status information of the passive Internet of Things terminal is updated to a normal state.

[0203] In the disclosed embodiment, when the target data received by the AIMF carries the terminal data of the passive Internet of Things terminal, it can be determined that the status of the passive Internet of Things terminal is normal. At this time, if the status information of the passive Internet of Things terminal was previously recorded as an abnormal state, it can be determined that the passive Internet of Things terminal has returned to normal, and the status information of the passive Internet of Things terminal can be updated from the abnormal state to the normal state.

[0204] In an exemplary embodiment, updating the terminal collection information of the passive Internet of Things terminal according to the target data may include:

[0205] When multiple target data corresponding to the passive Internet of Things terminal are received, if there is target data fed back by the base station bound to the passive Internet of Things terminal, the identification information of the base station bound to the passive Internet of Things terminal is not updated.

[0206] In the disclosed embodiment, when the passive IoT terminal is in the overlapping area of ​​multiple base stations, multiple target data will be fed back to the AIMF through the multiple base stations respectively. When the multiple target data fed back by the multiple base stations received by the AIMF all carry the terminal data of the same passive IoT terminal, the AIMF can determine the base station to which the passive IoT terminal is currently bound recorded locally. If the target data fed back by the base station to which the passive IoT terminal is currently bound exists in the multiple target data received, the identification information of the base station to which the passive IoT terminal is bound will not be updated.

[0207] In an exemplary embodiment, updating the terminal collection information of the passive Internet of Things terminal according to the target data may also include:

[0208] When multiple target data corresponding to a passive Internet of Things terminal are received, if there is no target data fed back by the base station bound to the passive Internet of Things terminal, the identification information of the base station bound to the passive Internet of Things terminal is updated according to the base station that is closest to the base station bound to the passive Internet of Things terminal among the base stations that feed back the target data.

[0209] In the disclosed embodiment, if the target data fed back by the base station to which the passive IoT terminal is currently bound does not exist in the received multiple target data, it can be determined that the passive IoT terminal has currently left the coverage of the bound base station, that is, it is unbound from the base station. Then, the base station closest to the base station to which the passive IoT terminal is bound can be determined from the base stations that feed back the multiple target data, and the base station is determined as the base station to which the passive IoT terminal is currently bound, and the identification information of the base station to which the passive IoT terminal is bound is updated to the identification information of the base station.

[0210] In an exemplary embodiment, referring to Figure 3 As shown, the above method may also include:

[0211] Step 302, receiving a terminal data acquisition request sent by a remote application function AF through a network capability exposure module NEF;

[0212] Step 304, according to the terminal data acquisition request, acquiring the target terminal acquisition information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request from the terminal acquisition information stored locally;

[0213] Step 306: Send the target terminal collection information to the NEF, so that the NEF forwards the target terminal collection information to the AF.

[0214] In the disclosed embodiment, when AF sends a terminal data acquisition request to NEF, NEF may forward the terminal data acquisition request to AIMF, wherein the terminal data acquisition request is used to indicate the acquisition of specified terminal data, for example: terminal data of a specified terminal and / or a specified data type and / or a specified data update time. After receiving the terminal data acquisition request, AIMF may respond to the terminal data acquisition request and obtain target terminal acquisition information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request from the terminal acquisition information stored locally, wherein when terminal acquisition information corresponding to the specified terminal and / or the specified data type is stored locally, it may be determined that there is terminal acquisition information that hits the terminal data acquisition request, and when the update time of the terminal acquisition information meets the data update time, it may be determined that the timeliness requirement of the terminal data acquisition request is met.

[0215] When the target terminal collection information that hits the terminal data acquisition request and meets the timeliness requirement of the terminal data acquisition request is obtained from the locally stored terminal collection information, the AIMF can send the target terminal collection information to the NEF, and the NEF forwards the target terminal collection information to the AF.

[0216] In an exemplary embodiment, referring to Figure 4 As shown, the above method also includes:

[0217] Step 402: When there is no target terminal collection information that hits the terminal data acquisition request and / or meets the timeliness requirement of the terminal data acquisition request in the locally stored terminal collection information, a data reporting request is sent so that the base station receiving the data reporting request broadcasts the data reporting request within the coverage area;

[0218] Step 404, receiving the target data fed back by the base station, and updating the terminal collection information of the passive Internet of Things terminal according to the target data;

[0219] Step 406, acquiring the target terminal acquisition information that hits the terminal data acquisition request from the locally stored terminal acquisition information;

[0220] Step 408: Send the target terminal collection information to the NEF, so that the NEF forwards the target terminal collection information to the AF.

[0221] In the disclosed embodiment, when there is no target terminal collection information that hits the terminal data acquisition request and / or there is no target terminal collection information that meets the timeliness requirements of the terminal data acquisition request in the terminal collection information locally stored by the AIMF, in order to meet the functional requirements of the AF, a data reporting request can be sent, so that the base station that receives the data reporting request can broadcast the data reporting request within the coverage area, so that the passive Internet of Things terminal that receives the data reporting request can feedback the terminal data to the base station, and the base station further sends the target data to the AIMF based on the terminal data fed back by the passive Internet of Things terminal. The AIMF updates the locally stored terminal collection information based on the target data sent by the base station, and determines from the updated terminal collection information whether there is target terminal collection information that hits the terminal data acquisition request. If so, the target terminal collection information is sent to the NEF, and the NEF forwards the target terminal collection information to the AF.

[0229] In the embodiments of the present disclosure, the interaction process and data processing process between the base station and the AIMF and the passive Internet of Things terminal may refer to the relevant description of the aforementioned embodiments, which will not be repeated here in the embodiments of the present disclosure.

Based on the management method of passive Internet of Things terminals provided by the embodiments of the present disclosure, a solution for network access and mobile management of passive Internet of Things terminals that are not equipped with SIM cards and do not have the ability to independently access the 3GPP core network can be provided, thereby improving the efficiency of network access and mobile management of passive Internet of Things terminals.

[0231] In one embodiment, Figure 6 As shown, a management method for a passive Internet of Things terminal is provided, and the method is applied to Figure 1 The passive IoT terminal in the example is used as an example to illustrate, including the following steps:

[0232] Step 602: receiving a data reporting request broadcasted by a base station, where the data reporting request is a data reporting request periodically sent by an integrated passive Internet of Things management function module AIMF, and AIMF is integrated in an access and mobility management module AMF;

[0237] In the embodiments of the present disclosure, the interaction process and data processing process between the passive Internet of Things terminal and the base station, and the base station and the AIMF may refer to the relevant description of the aforementioned embodiments, and will not be repeated in the embodiments of the present disclosure.

[0238] In the management method of passive Internet of Things terminals provided by the embodiments of the present disclosure, AIMF can periodically send a request for reporting data, and after the base station receives the request for reporting data, it broadcasts the request for reporting data within the coverage area; after the terminal receives the request for reporting data, it can feedback the terminal data to the base station, and after receiving the terminal data fed back by the passive Internet of Things terminal according to the request for reporting data, the base station reports the target data to AIMF according to the terminal data, so that AIMF updates the terminal collection information of the passive Internet of Things terminal according to the target data. Based on the management method of passive Internet of Things terminals provided by the embodiments of the present disclosure, a solution for network access and mobile management of passive Internet of Things terminals that are not equipped with SIM cards and do not have the ability to independently access the 3GPP core network can be provided, thereby improving the efficiency of network access and mobile management of passive Internet of Things terminals.

[0239] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the embodiments of the present disclosure are described below through specific examples.

[0240] For example, refer to Figure 7 As shown, A, B, and C are base station 1, base station 2, and base station n respectively. Figure 7 The coverage ranges of AP(1), AP(2), and AP(n) are shown in the figure. D is the area not covered by the radio access network RAN ​​(Radio Access Network). It is assumed that a passive IoT terminal Ambient UE moves from A to D.

[0241] Reference Figure 8aAs shown, when the passive IoT terminal Ambient UE moves from A to D, the AIMF also periodically sends a request to report data. During the movement, when the AIMF sends a request to report data for the first time, all base stations that receive the request to report data will broadcast the request to report data within their respective coverage areas. If the Ambient UE is in area A at this time, that is, the Ambient UE is within the coverage area of ​​AP (1), it will report its own terminal data (ID, stored data, etc.) to the AIMF through AP (1). After receiving the reported data, the AIMF will update the base station identifier bound to the Ambient UE to the identifier information of AP (1), that is, establish the corresponding information between the ID of the Ambient UE and AP (1), and update the latest stored data and collection time update time of the Ambient UE.

[0242] When the AIMF sends the data reporting request for the second time, if the Ambient UE has moved to area B, that is, the Ambient UE is within the coverage of AP(2), the Ambient UE will report its terminal data to the AIMF through AP(2). In this case, the AIMF updates the base station identifier bound to the Ambient UE to the identifier information of AP(2), that is, establishes the corresponding information between the ID of the Ambient UE and AP(2), and updates the latest stored data of the Ambient UE and the collection time update time.

[0243] When AIMF sends the data reporting request for the nth time, if the Ambient UE is in the area that is not covered by the network, such as area D, the terminal data cannot be reported. When AIMF does not receive the information reported by the Ambient UE, AIMF will judge the Ambient UE as "lost / damaged", and update the status information of the Ambient UE to an abnormal state, update the collection information update time, and mark the terminal status as "lost / damaged".

[0244] When AIMF sends the data reporting request for the mth time, if the Ambient UE has moved back to the area C covered by the network, the Ambient UE will re-report its ID and corresponding data to AIMF through AP(n) after receiving the request. AIMF updates the base station identifier bound to the Ambient UE to the identifier information of AP(n), that is, establishes the corresponding information of the ID of the Ambient UE and AP(n), and updates the latest stored data and collection time update time of the Ambient UE, and updates the status information of the Ambient UE from abnormal state to normal state.

[0245] If the Ambient UE is in the overlapping area of ​​two base stations (such as Figure 7 As shown, it is in the overlapping position of the two areas AB), since the network connection of the Ambient UE is not necessarily continuous, the Ambient UE may feed back terminal data to both base stations at the same time.

[0246] If AIMF receives data of the same Ambient UE reported by two or even multiple base stations at the same time, in a scenario, if one of the base stations is the same base station saved in the last update, that is, the base station bound to the currently recorded terminal, this base station is selected and the base station binding information is not updated, so as to reduce the number of updates and improve the management efficiency of passive IoT terminals.

[0247] In another scenario, if there is no base station saved in the last update among the two or more base stations, the base station closest to the base station saved in the last update is selected, and then the binding information between the Ambient UE and the base station is updated based on the base station, so as to improve the management accuracy of the passive IoT terminal.

[0248] Reference Figure 8b As shown, if the remote AF temporarily requests the data of the Ambient UE, the AF can send a terminal data acquisition request to the AIMF through the NEF. After receiving the terminal data acquisition request, the AIMF will first determine whether there is data stored locally that hits the terminal data acquisition request and meets the timeliness of the terminal data acquisition request. If so, the data will be returned directly through the NEF. If not, a data reporting request will be sent to all Ambient UEs through the base station to perform a data update. If there is data that hits the terminal data acquisition request after the update, the relevant data will be directly returned to the AF through the NEF. If the requested data is still not in the reported data, the AIMF will return data acquisition failure information to the AF through the NEF or return the status abnormality information of the requested Ambient UE, and the abnormal status is "lost / damaged".

[0249] The management method of passive Internet of Things terminals provided in the embodiments of the present disclosure is a mobility management solution designed for passive Internet of Things terminals that are not equipped with SIM cards and do not have the ability to independently access the 3GPP core network. The core is the related function enhancement design based on the access and mobility management network element AMF of the core network, and the related function extension of AMF.

[0250] Reference Fig. 9As shown, in the data reporting process, the data content of the data reported by the passive physical network terminal is: terminal ID + specific data, and the data reported by the base station to AMF is: data reported by the passive IoT terminal + base station ID + direction information of the passive IoT terminal. AMF / AIMF saves a list, which is used to record the correspondence between the passive IoT terminal AmbientIoT ID and the base station ID. AMF / AIMF saves the ID of the base station and the specific deployment location information of the base station. AMF / AIMF can determine the location information of the passive IoT terminal through the correspondence between the ID of Ambient IoT and the ID of the base station and the direction information of the passive IoT terminal reported by the base station. AMF / AIMF can open the location information of the passive IoT terminal to third parties through the network open function module NEF.

[0251] In the traditional 3GPP UE terminal mobility management method, because the terminal is always connected to the base station, when the UE moves to a remote area of ​​the base station or an overlapping area covered by the base station, the UE will actively report the signal strength information of different base stations it has received, and the wireless access network will actively switch the corresponding base station for the UE based on the specific signal strength information. At this time, the access and mobility management module (AMF) in the core network will save the location information of the terminal and update the base station information after real-time switching, so as to ensure the smoothness of network services, so that the UE can still smoothly receive network services even after switching different base stations. At the same time, when AMF provides mobility management services, AMF will not only update the latest location information of the UE, but also update the tracking area of ​​the UE.

[0252] The existing 3GPP mobile network does not provide access or related services for special terminals such as passive IoT terminals that are not equipped with SIM cards. The embodiments of the present disclosure provide a special mobility management solution assuming that such terminals can access the network. The existing technologies generally do not consider passive IoT terminals or require readers as intermediaries to enable the network side to manage passive IoT terminals. The solution provided by the embodiments of the present disclosure can enable the base station on the network side to directly assume the function of the reader and writer and directly connect to the passive IoT terminal to provide access and management services.

[0253] Passive IoT terminals are different from previous IoT terminals. Their low cost, simple structure and huge number will have a huge impact on the service design and provision on the network side. The disclosed embodiment breaks away from the previous mode in which the terminal actively reports information to the network side and then performs mobility management. It designs a set of methods in which the network side actively initiates requests to perform low-precision mobility management on passive IoT terminals. Under the premise of ensuring that a large number of passive IoT terminals can be covered, it not only provides mobility management services and meets the basic needs for mobility and positioning services, but also reduces the deployment cost and operating cost of the network side to respond to the massive passive IoT terminal services, and realizes the effective implementation of services under the principle of designing as simple and low-cost as possible.

[0254] In the existing network, passive IoT terminals are mainly concentrated on RFID (Radio Frequency Identification), and the deployment of RFID is mainly based on readers with network access functions. In addition, the actual transmission distance of RFID is only at the meter level. In this case, the network can actually manage the readers as traditional 3GPP terminals for the mobility management of passive IoT terminals. However, the problem is that the types of passive IoT terminals are limited and the scope of application is also limited. The disclosed embodiment jumps out of this limitation and can cover more types of passive IoT terminals while being compatible with RFID, and does not necessarily require the intervention of readers.

[0255] In the actual business of passive IoT terminals, there are already scenarios where base stations are directly connected to passive IoT terminals Ambient UE / Ambient IoT. In order to cover as many types of passive IoT terminals as possible, the disclosed embodiments can enable the network side to directly manage a large number of passive IoT terminals. At the same time, since the actual business requirements are not high, the network side can manage more passive IoT terminals at a lower cost.

[0256] The embodiments of the present disclosure can be applied to a variety of scenarios, such as nature reserves, urban road traffic, and intelligent management of large farms. In one example, when applied to a nature reserve, by placing passive IoT tags on protected animals that need special attention, the management method of the passive IoT terminal provided by the embodiments of the present disclosure is adopted, and the actual population migration and reproduction characteristics of animals are analyzed through periodic data reporting, so as to provide relevant data technology support for scientific research and environmental protection work.

[0257] In another example, when applied to an urban road traffic scenario, by installing passive IoT devices on vehicles such as cars or electric bicycles and adopting the management method of passive IoT terminals provided by the embodiments of the present disclosure, regular data collection and mobility information management can be performed, which can effectively analyze the periodic changes in the time distribution and the periodic changes in the geographical location distribution of urban traffic, and provide support for the reasonable development planning of the city.

[0258] In another example, when applied to the intelligent management of large farms, by placing passive IoT tags on animals that are managed outdoors in large commercial farms, the management method of the passive IoT terminal provided by the embodiment of the present disclosure can be used to collect the approximate location information of the animals and the survival status of the individuals, thereby providing support for low-cost automated farm management.

[0259] It should be understood that although Figure 1-9 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-9 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
