Abstract

The invention provides a network switching method, device and system, and a switching determination method and device. The network handover method includes: a mobility management function located in the core network of the first network receives a first handover request sent by a source base station connected to the core network of the first network, wherein the first handover request is used for requesting a user equipment UE connected to the source base station to switch from the source base station to a target base station, where the target base station is connected to the core network of the first network and / or the core network of the second network; according to the first Handover request, the mobility management function determines the core network of the target network that the UE accesses through the target base station after handover, where the core network of the target network is the core network of the first network or the The core network of the second network; the mobility management function initiates handover of the UE between the source base station and the target base station according to the core network of the target network.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a network switching method, device and system, and a switching determination method and device. Background technique [0002] 3GPP (3rd Generation Partnership Project) started to formulate the fourth generation (or called LTE, Long Term Evolution, long-term evolution) mobile communication system from R8. 3GPP began to study the next generation communication system (NextGen System) from R14, and formally formulated the 5G system specification in R15. [0003] The deployment of NextGen System (5G, hereinafter referred to as 5G) will initially be deployed locally in hot spots, such as city centers and commercial centers. When the UE accesses the 5G system, as the user moves, it moves out of the coverage of the 5G system. In order to ensure the continuity of the user's business (the IP address remains unchanged), the user UE is handed over to the 4G system. [0004] figure 1 It ...
