The invention discloses a processing method for ultra-mobile broadband characteristics. The processing method comprises the followings steps: S302, an actively concentrated access network of the access terminal determines whether to delete one or more characteristics and sends a request message for deleting the characteristics to a forward service access network; S304, under the circumstance thatthe forward service access network receives the requests for deleting the characteristics from the other actively concentrated members of the access terminal, or the forward service access network needs to initiate characteristic deletion, the forward service access network sends the message for deleting the characteristics to the access terminal; S306, the access terminal receives the request for deleting the characteristics and determines whether to delete one or more characteristics in a characteristic list, under the condition that the deletion is accepted, the acceptation message for deleting the characteristics is sent to a reverse service access network; S308, after receiving the acceptation message for deleting the characteristics, the reverse service access network sends the acceptation message for deleting the characteristics to all the actively concentrated access networks of the access terminal to inform the access networks to delete the corresponding characteristics; and simultaneously, after receiving the notification message for deleting the characteristics, the actively concentrated access network deletes the corresponding characteristics. Meanwhile, the invention also comprises a processing mechanism that the access terminal refuses to delete the characteristics.
