1. can provide to mobile communication station the method selecting access network the different access networks of service from multiple, it is characterized in that:

  • Determine the radio quality (S1) from terminal to each access network;

    Each access network is determined to the utilance factor (S2) of at least one node;

    For each access network, determine the user awareness quality of data (S3) according to the determined utilance factor of each access network and the determined radio quality of each access network, wherein compare biggest carrier speed and the determined user awareness quality of data to determine the best estimate of the user awareness quality of data;

    AndBest estimate based on the user awareness quality of data of each access network is selected at least one (S4) in the middle of access network;

    Based on the determined radio quality of each access network qestimate the radio link bit rate of each access μ

    ;

    And The user awareness quality of data is determined based on the radio link bit rate estimated by the determined utilance factor of each access network and each access;

    Wherein estimate described radio link bit rate according to following formula μ

    ;

    μ

    = g (q)Wherein g is access specific function;

    Wherein determine the described user awareness quality of data according to following formula qu(S3);

    Qu= μ

    * f (ρ

    ) Wherein μ

    represent described radio link bit rate, ρ

    represent the utilance factor of described access.
