Method and apparatus for processing service data

A method for processing service data, comprising:

• receiving a downlink service flow, wherein the downlink service flow comprises a second tunnel identifier and a source address;
• determining a second tunnel mapping table corresponding to the second tunnel identifier, wherein the second tunnel mapping table comprises one first tunnel identifier, the second tunnel identifier, and one or more service addresses corresponding to the second tunnel identifier;
• and
• transmitting the downlink service flow to a terminal corresponding to the first tunnel identifier.

An electronic apparatus for processing service data, comprising:

• a memory having instructions stored thereon;
• a processor configured to execute the instructions to perform operations comprising:
• receiving an uplink service flow, wherein the uplink service flow comprises a first tunnel identifier and a destination address;
• determining a first tunnel mapping table corresponding to the first tunnel identifier, wherein the first tunnel mapping table comprises the first tunnel identifier, one or more second tunnel identifiers corresponding to the first tunnel identifier, and one or more service addresses corresponding to each of the second tunnel identifiers;
• searching a service address the same as the destination address from the first tunnel mapping table;
• determining the second tunnel identifier of the uplink service flow based on the destination address if the searching is failed;
• and
• transmitting the uplink service flow to a service anchor corresponding to the second tunnel identifier of the uplink service flow, wherein the service anchor is configured to transmit the uplink service flow to a service server corresponding to the destination address.
