Mobile Edge Computing Processing Method and Related Device

A method comprising:

• receiving, by a radio access network device, a radio resource control (RRC) message sent by a terminal device, wherein the RRC message carries a protocol data unit (PDU) session setup request message requesting setting up a PDU session, and the PDU session setup request message is a non-access stratum (NAS) message;
• sending, by the radio access network device, a first message to a core network device, wherein the first message carries the PDU session setup request message;
• receiving, by the radio access network device from the core network device, a second message, wherein the second message carries an identifier of the PDU session and local computing request information, and the local computing request information comprises at least one of following information:
• a local computing function, a local computing algorithm, microservice information, or a local computing time budget;
• determining, by the radio access network device based on the second message, a first local computing device;
• and
• setting up, by the radio access network device, the PDU session between the first local computing device and the terminal device.

A local computing device, comprising:

• a transceiver, configured to:
• send local computing capability information to a radio access network device, wherein
• the local computing capability information comprises at least one of following information:
• a local computing function supported by the local computing device, a local computing algorithm supported by the local computing device, microservice information supported by the local computing device, an average processing delay of the local computing device, or current processing load of the local computing device;
• and
• receive, from the radio access network device, signaling for setting up a protocol data unit (PDU) session with a terminal device, the PDU session corresponding to a PDU session setup request message sent by the terminal device to the radio access network device, and the signaling being received based on the local computing capability information of the local computing device and the PDU session setup request message;
• and
• a processor, configured to set up the PDU session with the terminal device.
