摘要
The present invention provides a method for selecting a bearer mode, a packet gateway, and a policy and charging rule function entity, relating to the field of communications technologies, and solving the problem that a base station selects a suitable air interface transmission mode for a bearer of a mobile terminal. The method includes: receiving indication information of an air interface transmission mode supported by a mobile terminal; determining, according to the indication information and a received enhanced policy and charging control rule that is sent by a policy and charging rule function entity, an air interface transmission mode allowed to be used by a bearer bound with a service flow of the mobile terminal; and sending a session establishment reply message to a serving gateway to which the mobile terminal belongs, where the session establishment reply message comprises the air interface transmission mode allowed to be used by the bearer, so that the serving gateway sends, through a mobility management entity to which the mobile terminal belongs, the air interface transmission mode allowed to be used by the bearer to a base station to which the mobile terminal belongs for data transmission. The present invention is applicable to bearer mode selection.
