In step 101, after receiving service information sent by a user terminal, an SMF module determines a service requirement of the service information.
At step 102, the SMF module selects a UPF module associated with the service requirement based on the locally stored path policy.
In some embodiments, the SMF module determines whether a UPF module associated with the traffic demand exists based on the locally stored path policy. If there are UPF modules associated with the service requirement, the SMF module selects among the associated UPF modules. And if the UPF module associated with the service requirement does not exist, the SMF module selects the UPF module according to a preset rule.
For example, certain service information needs to be processed by a UPF module having a specific processing function. After the inquiry, a plurality of UPF modules are found to have the specific processing function, so that one UPF module can be selected from the UPF modules with the specific processing function. If no UPF module has this particular processing functionality, one UPF module may be selected according to predetermined rules. Thereby improving the compatibility of the system.
In step 103, the SMF module sends the service information and the corresponding path policy to the selected UPF module.
In step 104, after receiving the service information and the corresponding path policy, the UPF module creates a corresponding forwarding channel according to the path policy, so as to forward the service information.
In the service forwarding method provided by the foregoing embodiment of the present disclosure, a suitable UPF module is selected according to a service requirement, so that the routing pertinence can be improved. The method and the device are beneficial to realizing differentiated services and increasing the viscosity of the service.
