Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

In order to facilitate the understanding of the embodiments of the present application, the following technical points are first introduced below:

1. Introduction to 5G network architecture

The packet network architecture mainly includes radio access network (Radio Access Network, RAN), session management function (Session Management Function, SMF), access and mobility management function (Access and Mobility Management Function, AMF), user plane function (User Plane Function, UPF), policy control function entity (Policy Control Function, PCF), application function (Application Function, AF), unified data management (Unified Data Management, UDM) and other equipment, the network architecture is shown in Figure 1.

3. About tag communication introduction

As shown in Figure 2, Passive IoT (Passive IoT) is a low-cost, low-power IoT technology that can be based on passive tags, and currently there is a certain demand in industry and application.

4. Introduction to strong management scheme and weak management scheme

(1) Strong management solution: see Figure 3. Strong tag management means that the core network side manages tags through readers, and the core network side needs to authenticate and control tags. The technical details of this solution and the profitability of operators The model still needs further study.

Tag registration: tags are registered with the core network, and the core network performs lightweight authentication on tags;

Tag inventory: P-IoT AF searches for specific terminals through the core network according to certain rules, and reads the tag ID;

Tag access: After successful registration and authentication, the reader and tag execute the "access process", requiring operations such as reading/writing tags.

Tag information return: Tag information (tag ID must be carried, collection information is optional) is transmitted to P-IoT AF through the core network.

(2) Weak management solution: Refer to Figure 4. The tag weak management method means that the core network side only manages the readers, and the P-IoT tag is invisible to the core network side. Currently, operators do not consider this solution.

5. Introduction to label number allocation and management process

See Figure 5, the specific steps are as follows:

(0) Preparation stage

0.1. The enterprise pre-configures the ID and enterprise key of the label application when printing the label;

0.2. The AAA server (Server) pre-configures the ID and enterprise key of the label application when printing the label.

(1) Label online signing

1.1. The AMF sends a label configuration command to the RAN to trigger the signing of unsigned labels;

1.2. After receiving the tag configuration command, the RAN side performs an inventory of the tags covered by it;

1.3 The tag (P-IoT Tag) sends a registration request message (carrying the tag network ID-null) to the AMF through the RAN.

1.4. AMF requests "label network ID" and "Hash parameter" from AUSF/UDM;

1.5. AUSF/UDM sends "Tag Network ID" and "Hash Parameter" to AMF;

1.6. AMF sends "Tag Network ID" and "Hash Parameter" to RAN;

1.7. The tag (P-IoT Tag) can use the received Hash parameters to perform subsequent Hash operations.

(2) Tag registration + inventory

2.1. When P-IoT AF needs to make a positioning or data read and write operation for the tag (P-IoT Tag), it will issue tag inventory/read and write rules to AMF;

2.2. AMF sends an inventory command to RAN;

2.3. RAN performs an inventory process to the tag (P-IoT Tag);

2.4. The tag (P-IoT Tag) sends a registration request message ("Tag Network ID", RAND1, Token1 (obtained by Hash operation), "Tag Application ID") to AMF through RAN;

2.5. AMF executes Hash according to the received "Tag Network ID" and RAND1, and verifies Token1;

2.6. Optionally, an external certification label of the enterprise can also be carried out;

2.7. If both the core network internal authentication in 2.6 and the enterprise external authentication (optional) in 2.7 pass, the AMF receives the tag's registration request and returns a registration acceptance message.

(3) Tag reading and writing

3.1. The wireless side or other network elements initiate the process of reading and writing tags;

3.2. The tag side responds and returns the read and write operation results to AMF;

3.3. AMF returns tag inventory/reading and writing results to P-IoT AF.

(4) Tag online signing update

4.1. Tags can initiate an update process for online signing.

Referring to FIG. 6 , an embodiment of the present application provides a terminal mobility management method. The execution subject of the method includes but is not limited to a first network element (such as a core network element (such as AMF, etc.), a radio access network device (such as base station, etc.), etc.), the specific steps include: Step 601.

Step 601: Send a first message, the first message is used to indicate that the terminal performs an inventory and/or paging and/or paging and/or incentive and/or wake-up and/or update operation, so as to trigger the terminal to respond to the first network Yuan's first news.

It can be understood that, when the first network element is a network element of the core network, the first network element may send a first message to the radio access network device, and the first message indicates that the radio access network device is within the coverage area performing inventory and/or paging and/or paging and/or stimulating and/or waking up and/or updating operations on the terminal, so as to trigger the terminal to respond to the first message of the first network element;

Alternatively, when the first network element is a radio access network device (or described as a RAN network element), the first network element directly performs inventory and/or paging and/or paging and/or incentive and/or Or wake up and/or update operations to directly trigger the terminal to respond to the first message of the first network element.

The terminal herein may be understood as a passive IoT terminal (or described as a semi-passive terminal), which may include: a passive tag and/or a semi-passive tag.

In one embodiment of the present application, the first message is used to indicate that an inventory and/or paging and/or paging and/or incentive and/or wake-up and/or update operation is performed on the terminal to trigger the terminal to respond The first message of the first network element includes:

The first message is used to indicate that an inventory and/or paging and/or paging and/or incentive and/or wake-up and/or update operation is performed on the terminal, so as to trigger all terminals to respond to the first news;

or,

In one embodiment of the present application, the method also includes:

sending a second message, the second message requesting the location, tracking area, tracking area list, registration area, current One or more items in the first network element where it is located are updated.

For example, after the base station side receives the response message from the terminal, if the ULI of the tag (that is, the location information of the user terminal, including TAI, ECGI, TA List, etc.) changes, it needs to update the ULI of the current user to the AMF or other network elements (that is, the location information of the user terminal, including TAI, ECGI, etc.); for another example, if the AMF where the tag is located changes, it is necessary to update the AMF where the current user is located to the UDM or other network elements.

In this embodiment of the present application, the first message is used to instruct the wireless access network device to perform an inventory and/or paging and/or paging and/or incentive and/or wakeup and/or update operation on the terminals within the coverage area, so as to Triggering the terminal to respond to the first message of the first network element can reduce the overhead of mobility management of the terminal, reduce the consumption of device performance and network resources, and further prevent the terminal from It will not actively report the current TA List in real time, resulting in the problem that the network side cannot page the tag in the corresponding TA List, ensuring the reachability of terminal communication.

The execution subject of the method includes but is not limited to a first network element (such as a core network element (such as AMF, etc.), a radio access network device (such as base station, etc.), etc.), the specific steps include: step 701.

Step 701: Receive a third message from a third network element (such as NEF or other core network elements);

In an embodiment of the present application, the first network element completes one of the third message and an inventory message, an operation message, and a paging message at the granularity of the terminal and/or at the granularity of the first set. conversion between each other.

In one embodiment of the present application, one or more of the location set, tracking area, tracking area list, registration area, and current first network element of the terminals in the terminal group is the third The network element obtains it from a second network element (such as UDM, NEF, or other core network elements) by querying the identifier of the terminal group.

In the prior art, when NEF wants to perform an inventory operation on a certain group of users, it needs to query UDM Query the AMF where the current user is and the tracking area list (Tracking Area List, TA List) where the current user is. However, there will be a huge number of label users in the future. If feedback is performed at the user granularity, signaling and device performance will be greatly consumed. However, in the embodiment of the present application, the user location transmission mechanism based on the terminal group granularity effectively reduces the consumption of network resources.

Referring to FIG. 8 , an embodiment of the present application provides a terminal mobility management method, the execution body of the method includes but not limited to a radio access network device (such as a base station), and the specific steps include: Step 801 .

In this embodiment of the application, the overhead of terminal mobility management can be reduced, and the consumption of device performance and network resources can be reduced. Further, when a terminal moves across TA Lists, it can avoid TA List, which leads to the problem that the network side cannot page the tag in the corresponding TA List, ensuring the reachability of terminal communication.

Referring to FIG. 9 , an embodiment of the present application provides a terminal mobility management method. The execution subject of the method includes but is not limited to a terminal (or described as a passive IoT terminal or a semi-passive terminal). The specific steps include: Step 901 :

In the embodiment of this application, the first network element can obtain the latest location information of the terminal, so that when the terminal moves across the TA List, it can avoid the failure of the network side because the terminal will not actively report the current TA List in real time. The corresponding TA List paging the tag to ensure the reachability of terminal communication.

In one embodiment of the present application, the method also includes:

Through the identifier of the terminal group, query from the second network element to obtain the location set, tracking area set, tracking area list set, registration area set, and current location in the first network element set of the terminals in the terminal group. one or more.

In the embodiment of the present application, the device performance and network resource consumption are effectively reduced through the user location transfer mechanism at the terminal group granularity.
