1. a data transfer control method, is characterized in that, comprising:

  • IAD or access point obtain encrypts indication;

    According to the packet that needs to be encrypted in the data flow between the definite described IAD of described encryption indication and described access point;

    According to preset cipher mode, the described packet of encrypting that needs is encrypted to control;

    The described packet of described needs being encrypted according to preset cipher mode is encrypted to control and comprises;

    Judge that the encryption in the context that packet is corresponding indicates whether to encrypt for needs, if, IAD or access point are by self integrated crypto engine, according to preset cipher mode, described packet is encrypted, packet after encrypting and unencrypted packet are reformulated to data flow, described data flow is sent to opposite end by mobile management entity;

    Or,IAD or access point are to needing the packet of encrypting and not needing the packet of encrypting to identify respectively in described data flow, the data flow that carries the packet after sign is sent to encryption gateway, encryption gateway is classified to packet according to the package identification in the data flow receiving, the packet that needs are encrypted is encrypted, by the packet after encrypting and do not need the packet of encrypting to reformulate data flow, described data flow is sent to corresponding destination.
