Abstract: A terminal includes a first universal subscriber identity module (USIM) and a second USIM. A method for determining a paging occasion (PO) of the terminal includes, in response to a first PO of the first USIM being the same as a PO of the second USIM, sending, by the terminal, indication information to a mobility management network element communicating with the first USIM. The indication information is used to indicate that POs of at least two USIMs in the terminal are the same. The method also includes receiving, by the terminal, a first parameter from the mobility management network element. The method further includes determining, by the terminal, a second PO of the first USIM based on the first parameter. The second PO of the first USIM is different from the PO of the second USIM.

Abstract: Embodiments of this application disclose an overload control method and apparatus, and relate to the field of communications technologies, to help relieve overload of an access and mobility management network element (for example, an AMF network element). The method may include: An access network device receives indication information from an access and mobility management network element. The indication information is used to indicate that the access and mobility management network element is overloaded. When a terminal is in an RRC connected mode or an RRC inactive mode, the access network device triggers, based on the indication information and characteristic information of the terminal, setting the terminal to be in an RRC idle mode; or when a terminal is in an RRC connected mode, the access network device triggers, based on the indication information and characteristic information of the terminal, setting the terminal to be in an RRC inactive mode.

Abstract: Embodiments of this application provide a communication method and a communications apparatus, to implement a purpose that a terminal can perform normal communication without local authentication. In the embodiments of this application, the method includes: receiving, by a mobility management network element, a request message that is from a terminal and that is used to request access to a network; and triggering, by the mobility management network element, third-party authentication when the mobility management network element determines, based on the request message, to perform third-party authentication on the terminal. In this case, after authentication is performed between the terminal and a third party, even if local authentication is not performed, the terminal may access the network for communication after third-party authentication is performed.

Abstract: This application discloses an information exchange method and apparatus. In the method, a terminal device transmits attach request information to a core network device, receives attach accept information of the core network device, where the attach accept information includes a first integrity check code; the terminal device obtains a second integrity check code based on the attach accept information; and the terminal device obtains, if the first integrity check code is the same as the second integrity check code, a third integrity check code based on encrypted attach complete information, and transmits encrypted attach complete information to which the third integrity check code is added to the core network device. This reduces data exchange procedures, reduces an amount of data of exchanged information, and reduces a time consumed in an information exchange process performed between the terminal device and the core network device.
