Abstract
A method for offloading processing service, comprising: acquiring a first packet carrying payload data and transmitted 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.
Claims6
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.

A communication apparatus, comprising:
- a memory having instructions stored therein,
- a processor coupled with the memory, wherein the instructions configure the processor to:
- acquire a first packet carrying payload data and transmitted wirelessly from a user equipment;
- identify a service type of the first packet by using Deep Packet Inspection DPI technique;
- determine 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
- transmit, via the determined transmission channel interface, the first packet to the destination end to which the user equipment requests for access;
- wherein the processor is further configured to:
- acquire a link establishment request message transmitted from the user equipment,
- determine a protocol type of a transmission layer protocol carried in the link establishment request message;
- establish a link from the communication apparatus to the user equipment and a link from communication apparatus to a next-hop network element if the transmission layer protocol carried in the link establishment request message is the TCP protocol;
- releasing the established link from the communication apparatus to the next-hop network element and re-establishing a link from the communication apparatus to the destination end via the determined transmission channel interface if the established link from the communication apparatus to the next-hop network element is not the link that corresponds to the determined transmission channel interface, and
- transmit, 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.
