Abstract: Provided are an address allocation method and apparatus, a core network, a node, a network system and a medium. In at least one of the case of establishing a session, at least two uplink addresses are configured and send to an access network. The access network is a connectivity network formed by a coupling of at least two network element nodes. At least part of the at least two uplink addresses are used for being allocated among the network element nodes. The access network receives the at least two uplink addresses sent by the core network and allocates the at least two uplink addresses. The access network sends at least one downlink address to the core network and determines usage of the uplink addresses. The access network may determine a correspondence between the uplink address and the downlink address. The core network receives the downlink address.

Abstract: Provided are method and apparatus for maintaining an air interface inactive state. The method includes: receiving an RRC uplink notification message sent by a UE, the RRC uplink notification message carrying information notifying that the UE is out of coverage of a serving cell under a source secondary node; performing, based on the RRC uplink notification message, a migration operation of a related high-level configuration of a PDU session anchored to the source secondary node by the UE, a migration target node being a target secondary node or a current master node; and sending an RRC downlink reply message to the UE after performing the migration operation of the high-level configuration, and maintaining the UE in a dual-connectivity or single-connectivity air interface inactive state.

Abstract: Provided are an optimized processing method and apparatus for service migration of a terminal. According to the optimized processing method, when the terminal conducts service transmission with a network or when the terminal performs service migration between a source network element and a target network element, service performance information of the terminal is acquired. By means of the technical solution, the technical problem in the related art that the service performance or service experience, etc. of a terminal is not taken into account during service transmission between a terminal and a network or during service migration of a terminal is solved, so the service performance and service experience can be obtained when the terminal conducts service transmission or service migration, thereby providing a powerful support for optimizing the service migration or service transmission of the terminal and improving the experience of a user.
