Summary: | The present disclosure provides a user plane gateway updating method and apparatus, so as to resolve a prior-art technical problem that GW-U updating cannot be implemented when neither an MME nor a GW-C changes. Embodiments of the present disclosure provide four different solutions, for purposes of being compatible with an existing implementation mechanism and improving system efficiency, when a UE performs TAU, an EPS system of a distributed gateway can select, according to a current location of the UE, a best GW-U and re-establish a PDN connection, thereby optimizing a data transmission path and ensuring communication performance. |
