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.

An apparatus, comprising:
- 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, wherein the uplink classifier user plane function network element is configured to offload a service flow of a terminal device;
- and
- 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.
An apparatus, comprising:
- a processor;
- and
- a memory having instructions stored thereon that, when executed by the processor, cause the apparatus to:
- in response to determining a terminal device moved to a visited location, insert an intermediate user plane function network element at the visited location;
- and
- receive an address of an uplink classifier user plane function network element from a session management function network element at a home location, wherein the uplink classifier user plane function network element is configured to offload a service flow of the terminal device.
An apparatus, comprising:
- a processor;
- and
- a memory having instructions stored thereon that, when executed by the processor, cause the apparatus to:
- in response to determining a terminal device moved to a visited location, insert an uplink classifier user plane function network element at the visited location, wherein the uplink classifier user plane function network element is configured to offload a service flow of the terminal device;
- and
- send a second offloading rule to the uplink classifier user plane function network element, wherein the second offloading rule indicates to send a service flow that matches the second offloading rule to a primary anchor user plane function network element at a home location, and the primary anchor user plane function network element is connected to a local data network at the home location.
