2. The method of claim 1, wherein the data splitting device comprises: the method specifically comprises the following steps of:

receiving data sent by a terminal through a base station by the first split UPF, detecting whether the data is the data sent to a first private network, if the data is the data sent to the first private network, forwarding the data to the first private network by the first PSAPPF according to a preset first split rule, and if the data is not the data sent to the first private network, forwarding the data to the second split UPF by the first split UPF;

and detecting whether the data is the data sent to the second private network or not through the second split UPF, if the data is the data sent to the second private network, forwarding the data to the second private network through the second PSAPPF according to a preset second split rule, and if the data is not the data sent to the second private network, forwarding the data to a preset data network through the third PSA UPF.

3. The method of claim 2, wherein the first split UPF comprises a first uplink classifier UL CL UPF or a first bifurcation point BP UPF, and/or wherein the second split UPF comprises a second UL CL UPF or a second BP UPF.

4. The method according to claim 1, characterized in that the first offload rule is preconfigured by a session management function, SMF, or policy control function, PCF, based on the destination internet protocol, IP, address and/or port of the first private network and/or the second offload rule is preconfigured by a SMF or PCF based on the destination IP address and/or port of the second private network.

5. A data splitting apparatus, the apparatus being configured to:

receiving data sent by a terminal through a base station;

detecting whether the data is the data sent to the first private network or not, and if the data is the data sent to the first private network, forwarding the data to the first private network according to a preset first splitting rule;

if the data is not the data sent to the first private network, detecting whether the data is the data sent to the second private network, if the data is the data sent to the second private network, forwarding the data to the second private network according to a preset second splitting rule, and if the data is not the data sent to the second private network, forwarding the data to a preset data network.

6. The apparatus of claim 5, wherein the data splitting means comprises: a first split user plane function, UPF, a second split UPF, a first session anchor, PSA, UPF, and a third PSA UPF;

the first split UPF is configured to receive data sent by a terminal through a base station, detect whether the data is data sent to a first private network, if the data is data sent to the first private network, forward the data to the first private network through the first PSA UPF according to a preset first split rule, and if the data is not data sent to the first private network, forward the data to the second split UPF through the first split UPF;

the second split UPF is configured to detect whether the data is data sent to the second private network, if the data is data sent to the second private network, forward the data to the second private network through the second PSA UPF according to a preset second split rule, and if the data is not data sent to the second private network, forward the data to a predetermined data network through the third PSA UPF.

7. The apparatus of claim 6, wherein the first split UPF comprises a first uplink classifier UL CL UPF or a first bifurcation point BP UPF, and/or wherein the second split UPF comprises a second UL CL UPF or a second BP UPF.

8. The apparatus of claim 5, wherein the first offload rule is preconfigured by a session management function, SMF, or policy control function, PCF, based on a destination internet protocol, IP, address and/or port of the first private network, and/or wherein the second offload rule is preconfigured by the SMF or PCF based on a destination, IP, address and/or port of the second private network.

9. An electronic device, comprising:

one or more processors;

a memory having one or more programs stored thereon, which when executed by the one or more processors, cause the one or more processors to implement the method of any of claims 1-4;

one or more I/O interfaces coupled between the processor and the memory configured to enable information interaction of the processor with the memory.

10. A computer readable medium having stored thereon a computer program which, when executed by a processor, implements a method according to any of claims 1 to 4.
