The embodiment of the invention discloses an access point name configuration method and a mobile terminal. The method comprises the following steps: the mobile terminal analyzes bearing information of a public data network PDN bearing to acquire an access point name APN; the mobile terminal detects whether a target APN matched with the bearing APN exists in an APN mapping list of the mobile terminal; if the target APN matched with the bearing APN is inexistent in the APN mapping list of the mobile terminal, the mobile terminal adds the bearing APN and an identity ID of the target network in the APN mapping list, wherein the target network is corresponding to the bearing APN; the mobile terminal uses the bearing APN to initiate a data dialing request to the target network. Through the adoption of the method disclosed by the invention, the data call request can be performed by use of the APN in a default PDN bearing.
