A method for enabling a routing function, comprising: when a station uses an external network identifiable address and performs data transmission of a single session task through a first access point, determining an address of a club routing function, CR, router connected to the first access point; characterized by further comprising: determining at least one second access point, wherein the second access point and the first access point are connected to the same CR router; the first access point and the second access point are access points associated with the CR of the station; sending a CR enabling request message to a CR router corresponding to the CR router address through each of the access points associated with the CR of the station, wherein the external network identifiable address used by the station and an available bandwidth resource allocated to the station by an access point forwarding the CR enabling request message are recorded in the CR enabling request message; and receiving a CR enabling feedback message, wherein the CR enabling feedback message is returned by the CR router and forwarded via the access points associated with the CR of the station, so that the station sends different data packets of the single session task through the first access point and the second access point separately. when a station uses an external network identifiable address and performs data transmission of a single session task through a first access point, determining an address of a club routing function, CR, router connected to the first access point; characterized by further comprising: determining at least one second access point, wherein the second access point and the first access point are connected to the same CR router; the first access point and the second access point are access points associated with the CR of the station; sending a CR enabling request message to a CR router corresponding to the CR router address through each of the access points associated with the CR of the station, wherein the external network identifiable address used by the station and an available bandwidth resource allocated to the station by an access point forwarding the CR enabling request message are recorded in the CR enabling request message; and receiving a CR enabling feedback message, wherein the CR enabling feedback message is returned by the CR router and forwarded via the access points associated with the CR of the station, so that the station sends different data packets of the single session task through the first access point and the second access point separately. determining at least one second access point, wherein the second access point and the first access point are connected to the same CR router; the first access point and the second access point are access points associated with the CR of the station; sending a CR enabling request message to a CR router corresponding to the CR router address through each of the access points associated with the CR of the station, wherein the external network identifiable address used by the station and an available bandwidth resource allocated to the station by an access point forwarding the CR enabling request message are recorded in the CR enabling request message; and receiving a CR enabling feedback message, wherein the CR enabling feedback message is returned by the CR router and forwarded via the access points associated with the CR of the station, so that the station sends different data packets of the single session task through the first access point and the second access point separately.
