2 . The access network device according to claim 1 , wherein the first information comprises:
routing-related information;
wherein the routing-related information comprises at least one of: a routing-related identity or routing path information; or
the first information comprises at least one of: a device manufacturer identity, a service provider identity, or an identity of the terminal device.

3 . The access network device according to claim 2 , wherein the uplink data information comprises an uplink data container;
wherein the first information is carried by a header portion of the uplink data container, or the first information is carried by a data portion of the uplink data container.

4 . The access network device according to claim 2 , wherein the access network device performs:
determining the first core network device based on the routing-related information in the first information in the uplink data information; or determining the first core network device based on the first information in the uplink data information and first pre-configuration information.

5 . The access network device according to claim 4 , wherein the first pre-configuration information comprises: a parameter of a candidate device corresponding to a candidate server and supported by each candidate core network device of one or more candidate core network devices; the parameter of the candidate device corresponding to the candidate server comprises at least one of: an identity of a candidate device manufacturer, an identity of a candidate service provider, or an identity of a candidate device.

6 . The access network device according to claim 1 , wherein the access network device performs:
receiving the uplink data information sent from the terminal device through an access stratum (AS) connection between the access network device and the terminal device.

7 . The access network device according to claim 1 , wherein the access network device further performs:
receiving downlink data information sent from the first core network device; wherein the downlink data information is response information for the uplink data information; and sending the downlink data information to the terminal device.

8 . A first core network device, comprising: a processor and a memory, wherein the memory is configured to store a computer program, the processor is configured to invoke and execute the computer program stored in the memory, to cause the first core network device to perform:
receiving uplink data information; determining a target server based on first information in the uplink data information; and sending the uplink data information to the target server.

9 . The first core network device according to claim 8 , wherein the first information comprises:
routing-related information;
wherein the routing-related information comprises at least one of: a routing-related identity or routing path information; or
the first information comprises at least one of: a device manufacturer identity, a service provider identity, or an identity of a terminal device.

10 . The first core network device according to claim 9 , wherein the uplink data information is an uplink data container;
wherein the first information is carried by a header portion of the uplink data container, or the first information is carried by a data portion of the uplink data container.

11 . The first core network device according to claim 9 , wherein the first core network device performs:
determining the target server based on the routing-related information in the first information in the uplink data information; or determining the target server based on the first information in the uplink data information and second pre-configuration information.

12 . The first core network device according to claim 11 , wherein the second pre-configuration information is shared by one or more candidate core network devices, and the one or more candidate core network devices comprise the first core network device; and
the second pre-configuration information comprises: a parameter of a candidate device corresponding to each candidate server of one or more candidate servers; wherein the parameter of the candidate device comprises at least one of: an identity of the candidate device, a service area of the candidate device, an identity of a candidate device manufacturer, or an identity of a candidate service provider.

13 . The first core network device according to claim 8 , wherein the first core network device performs:
receiving the uplink data information sent from an access network device; or receiving the uplink data information carried by an uplink NAS transport message and sent from the terminal device; or receiving the uplink data information carried by a control plane service request message and sent from the terminal device.

14 . The first core network device according to claim 13 , wherein the first core network device further performs:
receiving a registration request message sent from the terminal device through an access network device; sending a registration accept message to the terminal device through the access network device; wherein the registration accept message is used to indicate that an establishment of the NAS connection between the terminal device and the first core network device have been completed; and receiving a registration completion message sent from the terminal device through the NAS connection.

15 . A terminal device, comprising: a processor and a memory, wherein the memory is configured to store a computer program, the processor is configured to invoke and execute the computer program stored in the memory, to cause the terminal device to perform:
sending uplink data information; wherein first information in the uplink data information is used to determine a first core network device and/or a target server.

16 . The terminal device according to claim 15 , wherein the first information comprises:
routing-related information;
wherein the routing-related information comprises at least one of: a routing-related identity or routing path information; or
