Step 410, ANDSF equipment generate access strategy to the QoS information higher than the user of preset value, described
The coverage of the access network is carried in access strategy.
Specifically, the QoS information of business ordered according to the QoS information of user or user of ANDSF equipment to
Family generates new access strategy, and the corresponding user of different stage QoS information corresponds to different access strategies, example respectively
Such as the access strategy (covering radius R1) in the strong region of QoS level user's above-mentioned level of signal of correspondence high, QoS
The access strategy (covering radius R3) in the low region of the low user's above-mentioned level of signal of correspondence of rank, QoS level position
The access strategy (covering radius R2) in the region in user's above-mentioned level of signal of correspondence between height.
Further, if ANDSF equipment obtain be user QoS information, to QoS higher than preset value
User generates new access strategy, for example, generate the access strategy in the strong region of above-mentioned level of signal；If ANDSF
Equipment obtain be user order business QoS information, then to QoS higher than preset value business corresponding to use
Family generates new access strategy, for example, generate the access strategy in the strong region of above-mentioned level of signal.Wherein, step 410
In preset value can flexibly be determined according to the particular content of QoS information, for example QoS information be the grade of service, then
Preset value can be the default grade of service.
