23. The method of claim 20, wherein the second indication information is a cause value.

24. The method of claim 20, wherein the second indication information further includes a second list, and the second list is used to indicate a service configuration list that the core network side device uses an unlicensed frequency band for the terminal.

25. The method of claim 19, wherein after performing the first action, the method further comprises:

and sending third indication information to the terminal, wherein the third indication information is used for indicating the execution result of the first behavior.

26. The method of claim 19, wherein after performing the first action, the method further comprises:

and sending fourth indication information to access network side equipment, wherein the fourth indication information is used for indicating an execution result of the first behavior.

27. The method of claim 26, wherein the fourth indication information further comprises one of:

a first list;

a third list;

28. The method of claim 27, wherein traffic outside of the first list uses licensed bands by the terminal.

29. A method according to claim 19 or 27, wherein traffic outside the third list uses licensed bands by the terminal.

30. An apparatus for using unlicensed frequency bands, comprising:

wherein the first information comprises at least one of:

the first indication information;

subscription information of the terminal;

network load conditions;

a local policy;

the first behavior comprises at least one of:

receiving the unlicensed frequency band used by the terminal;

refusing the terminal to use the unlicensed frequency band;

receiving service preference information in the first list of the terminal;

negotiating a third list with the terminal;

31. A method for using an unlicensed frequency band, performed by an access network-side device, includes:

32. The method of claim 31, further comprising:

and sending second indication information to the terminal through a second broadcast indication, wherein the second indication information is used for indicating that the terminal uses the unlicensed frequency band.

33. The method of claim 31, wherein the second indication information further includes a second list, and the second list is used to indicate a service configuration list of a core network side device for using an unlicensed frequency band for the terminal.

34. The method of claim 31, further comprising:

receiving fourth indication information sent by a core network side device, where the fourth indication information is used to indicate an execution result of a first behavior executed by the core network side device, and the first behavior includes at least one of the following:

receiving the unlicensed frequency band used by the terminal;

refusing the terminal to use the unlicensed frequency band;

receiving service preference information in a first list of the terminal;

negotiating a third list with the terminal;

35. The method of claim 34, wherein traffic outside of the first list uses licensed bands by the terminal.

36. The method of claim 34, wherein traffic outside of the third list uses licensed bands by the terminal.

37. The method of claim 34, wherein the fourth indication information further comprises one of:

the first list;

the third list.

38. An apparatus for using unlicensed frequency bands, comprising:

a third executing module, configured to obtain a first broadcast instruction, where the first broadcast instruction is used to indicate that the access network side device supports or does not support a terminal to use an unlicensed frequency band;

39. A terminal comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, the program or instructions when executed by the processor implementing the steps of the method of using unlicensed frequency bands according to any of claims 1 to 17.

40. A core network side device comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, the program or instructions when executed by the processor implementing the steps of the method for using unlicensed frequency bands according to any one of claims 19 to 29.

41. An access network-side device comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method for using unlicensed frequency bands according to any one of claims 31 to 37.

42. A readable storage medium, storing thereon a program or instructions which, when executed by a processor, implement the method of using unlicensed frequency bands according to any one of claims 1-17, or the steps of the method of using unlicensed frequency bands according to any one of claims 19-29, or the steps of the method of using unlicensed frequency bands according to any one of claims 31-37.
