Abstract

The embodiment of the invention provides a method for realizing communication continuity and related equipment. The method is applied to an AF corresponding to UE, and the UE establishes a connection with a source AS by using allocated UE source network address information. The method comprises the following steps: determining to migrate a source AS to a target AS; transmitting the first NAT parameter to the SMF, so that the SMF determines a target UPF / PSA, wherein the target UPF / PSA is used for redistributing UE target network address information for the UE, generating and returning a second NAT parameter to the SMF according to the first NAT parameter, the UE source network address information and the UE target network address information, and performing NAT conversion on the received data packet according to the second NAT parameter; obtaining a second NAT parameter from the SMF; and configuring a third NAT parameter for the target AS according to the second NAT parameter, and migrating the source AS to the target AS, so that the target AS performs NAT conversion on the data packet according to the third NAT parameter.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, relates to a method for realizing communication continuity, an application function, a target application server, a session management function, user equipment, and a computer-readable storage medium. Background technique [0002] When the AS (Application Server, application server) is migrated, the network address of the AS will change, and at this time, the communication between the UE (User Equipment, user equipment) and the AS will be interrupted, resulting in interruption of ongoing service communication. Therefore, a technical problem that needs to be solved is: when the UE moves, how to relocate the AS to maintain service continuity (such as communication delay is small); or, when the AS relocates but the UE does not move, how to maintain Continuity of business (eg communication delays are minimal). [0003] In related technologies, after the AS migrates ...
