Method for data bypass, network side equipment and access gateway

The embodiment of the invention provides a method for a data bypass, network side equipment and an access gateway. The method for the data bypass comprises the following steps that: the network side equipment receives a first request message sent by user equipment; after determining that an access point name in the first request message is the access point name of an identification bypass service, the network side equipment changes the access point name of the identification bypass service into the access point name pointing to a GGSN; and the network side equipment sends a second request message which carries the access point name pointing to the GGSN to the GGSN so as to establish a channel between the access gateway and the GGSN, wherein the GGSN is the GGSN deployed together with the access gateway or the GGSN integrated with the access gateway. The embodiment of the invention realizes the data bypass supporting function of the access gateway.
