A method for obtaining a serving gateway according to an embodiment of the present invention includes: when a UE is switched from an old-side mobility management node to a new-side mobility management node, sending, by the new-side mobility management node, a domain name resolution request to a domain name system DNS server according to access information of the UE; receiving a hostname of a device returned, according to the domain name resolution request, by the DNS server; obtaining a hostname of a new-side available S-GW; and selecting the new-side available S-GW closest to the device on geographic topology as a new-side S-GW. User service data transmission time delay can be reduced through the method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for obtaining serving gateway, mobility management node, data gateway, and system","description":"The present invention provides a method for obtaining a serving gateway, a mobility management node, a data gateway, and a system.
