Abstract:
1. A method for offloading processing service, comprising: acquiring a first packet carrying payload data and transmitted wirelessly from a user equipment; identifying a service type of the first packet by using Deep Packet Inspection DPI technique; determining a transmission channel interface that corresponds to the identified service type according to a first correspondence relationship between service types and transmission channel interfaces; and transmitting, via the determined transmission channel interface, the first packet to a destination end to which the user equipment requests for access; wherein before the acquiring a first packet carrying payload data and transmitted wirelessly from the user equipment, further comprising: acquiring a link establishment request message transmitted from the user equipment; and establishing, if it is determined that a transmission layer control protocol TCP connection is needed to be established according to the link establishment request message, a link from the network element of the access network to the user equipment and a link from the network element of the access network to a next-hop network element; wherein before the transmitting, via the determined transmission channel interface, the first packet to the destination end to which the user equipment requests for access, further comprising: releasing, if the established link from the network element of the access network to the next-hop network element is not the link that corresponds to the determined transmission channel interface, the established link from the network element of the access network to the next-hop network element and re-establishing a link from the network element of the access network to the destination end via the determined transmission channel interface; wherein the transmitting, via the determined transmission channel interface, the first packet to the destination end to which the user equipment requests for access comprising: transmitting, over the re-established link via the determined transmission channel interface, the first packet to the destination end to which the user equipment requests for access.
