wherein the first terminals and the second terminal are mobile terminals.

2. The method according to claim 1 , wherein the expected terminal behavioral information comprises one or more of a stationary indication, a terminal moving trajectory, a periodic communication indicator, a communication duration, a communication period, or a scheduled communication time.

3. The method according to claim 1 , wherein the expected terminal behavioral information comprises mobility management type information or session management type information.

4. The method according to claim 1 , wherein:

the first core network element is an access and mobility management function network element and the second core network element is a session management function network element; or

the first core network element is the session management function network element and the second core network element is the access and mobility management function network element.

5. A system comprising:

a data analytics network element comprising:

at least one processor; and

a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the data analytics network element to:

obtain terminal behavioral information of a plurality of first terminals;

determine expected terminal behavioral information based on the terminal behavioral information of the plurality of first terminals;

send the expected terminal behavioral information to a first core network element;

receive, from the first core network element, first terminal behavioral information of a second terminal based on the first core network element's determination from a comparison of the first terminal behavior information of the second terminal to the received expected terminal behavior information from the data analytics network element, wherein the first terminal behavioral information of the second terminal does not match the expected terminal behavioral information, and wherein the second terminal is one of the plurality of first terminals;

receive, from a second core network element, second terminal behavioral information of the second terminal;

determine exception information of the second terminal based on the first terminal behavioral information of the second terminal and the second terminal behavioral information of the second terminal; and

send the exception information of the second terminal to a policy control function network element; and

wherein the first terminals and the second terminal are mobile terminals.

6. The system according to claim 5 , wherein the expected terminal behavioral information comprises one or more of: a stationary indication, a terminal moving trajectory, a periodic communication indicator, a communication duration, a communication period, or a scheduled communication time.

7. The system according to claim 5 , wherein the expected terminal behavioral information comprises mobility management type information or session management type information.

8. The system according to claim 5 , wherein:

the first core network element is an access and mobility management function network element and the second core network element is a session management function network element; or

the first core network element is the session management function network element and the second core network element is the access and mobility management function network element.

9. A data analytics network apparatus comprising:

at least one processor; and

a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the data analytics network apparatus to:

obtain terminal behavioral information of a plurality of first terminals;

determine expected terminal behavioral information based on the terminal behavioral information of the plurality of first terminals;

send the expected terminal behavioral information to a first core network element;

receive, from the first core network element, first terminal behavioral information of a second terminal based on the first core network element's determination from a comparison of the first terminal behavior information of the second terminal to the received expected terminal behavior information from the data analytics network apparatus, wherein the first terminal behavioral information of the second terminal does not match the expected terminal behavioral information, and

wherein the second terminal is one of the plurality of first terminals;

receive, from a second core network element, second terminal behavioral information of the second terminal;

send the exception information of the second terminal to a policy control function network element; and

wherein the first terminals and the second terminal are mobile terminals.

10. The apparatus according to claim 9 , wherein execution of the programming instructions by the at least one processor further causes the apparatus to send a request message to the second core network element before receiving the second terminal behavioral information of the second terminal, and wherein the request message requests the second terminal behavioral information of the second terminal.
