Abstract: Embodiments of the present invention provide a gateway system and a communication method. The gateway system includes: a control plane entity, connected or integrated with a mobility management network element, and configured to allocate an IP address to UE and configure a data path for connecting a user plane entity with an RAN, a PDN or another gateway; one or more user plane entities, located between the PDN and the RAN, independent of the control plane entity, configured to forward data on the data path configured by the control plane entity. The gateway system is composed of the control plane entity and the user plane entity which are independent of each other, the number of the user plane entities may be independently changed to adapt to the change of network traffic without replacing all gateway entities, the network deployment is more convenient and the cost is lower.

Abstract: An application server switching method, applied to a scenario in which a handover occurs between user plane network elements corresponding to a terminal device, includes obtaining, based on a user plane network element of the user plane network elements after the handover and a correspondence between the user plane network element and an address of a local application server of one or more application servers deployed on a network, the address of the local application server corresponding to the user plane network element after the handover. The correspondence between the user plane network element and the address of the local application server is used to indicate the address of the local application server. The method also includes sending the address of the local application server corresponding to the user plane network element after the handover.

Abstract: Embodiments of this application provide a data transmission method, apparatus, and device. The method includes: A first apparatus obtains a first link quality packet message, where the first link quality packet message includes link quality information and indication information, and the indication information is used to indicate that the link quality information is buffered; and the first apparatus sends the first link quality packet message to a second apparatus, where the first link quality packet message is used by the second apparatus to perform network optimization based on the first link quality packet message. This improves accuracy of network optimization.
