Abstract: This application provides a method for processing a change in a radio capability of a terminal apparatus and an apparatus. The method includes: receiving, by an access network apparatus, indication information, where the access network apparatus stores radio capability information of a terminal apparatus, and the indication information is used to indicate that a radio capability of the terminal apparatus changes, or is used to request a current radio capability of the terminal apparatus from the access network apparatus; and obtaining, by the access network apparatus, radio capability information of the terminal apparatus according to the indication information. According to this application, communication efficiency of a radio control resource connection performed when a radio capability of the UE changes in a suspend state can be improved.

Abstract: A session establishment method and apparatus are provided. The method includes: determining, by a first network device, whether an air interface resource of a default flow of a PDU session is successfully established; and if the air interface resource of the default flow of the PDU session fails to be established, the first network device, based on first information, establishes the PDU session in an inactive state or triggers to release the PDU session, where the first information is used to indicate whether establishment of the PDU session in the inactive state is allowed when the air interface resource of the default flow of the PDU session fails to be established.

Abstract: This application relates to the field of communications technologies. This application discloses a method, an apparatus, a network device, and a system for releasing an IP (Internet protocol) address, to resolve a problem that a time at which the IP address is released is not precise. The method includes: determining, by the first network device, that a PDU session anchor needs to be relocated from a first user plane function entity, where the first user plane function entity is the PDU session anchor of a first PDU session of a terminal; determining, by the first network device, that a first IP address of the terminal is no longer used, where the first IP address is an IP address used by the terminal in the first PDU session; and releasing, by the first network device, the first IP address.
