Abstract: An apparatus includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the apparatus to insert an uplink classifier user plane function network element at a home location. The uplink classifier user plane function network element is configured to offload a service flow of a terminal device. The apparatus is also caused to, in response to determining the terminal device moved to a visited location, send an address of the uplink classifier user plane function network element to an intermediate user plane function network element at the visited location to establish a tunnel between the intermediate user plane function network element and the uplink classifier user plane function network element.

Abstract: The present disclosure discloses a method for redirecting data by using a service proxy, including: forwarding, according to a data storage path carried in a received first data request message sent by a client, the first data request message to a data server; receiving a redirection response message sent by the data server, where the redirection response message carries a new path for storing requested data; sending, according to the new path for storing the requested data, a second data request message to a data server that is indicated by the new path; receiving data that is requested by the client and is sent by the data server that is indicated by the new path, and sending the requested data to the client. According to the method data acquiring efficiency is improved and a network delay is reduced.
