3GPP networks are as specified Non-3GPP networks.
Such as：In multiple Non-3GPP networks, selection signal intensity is more than the Non-3GPP of first threshold (such as 65dBm)
Network if the Non-3GPP networks that signal intensity is more than first threshold have multiple, is being believed as specifying Non-3GPP networks
Number intensity is more than in the Non-3GPP networks of first threshold, selects packet loss to be less than the Non-3GPP nets of Second Threshold (such as 10%)
Network is as specified Non-3GPP networks；If packet loss be less than Second Threshold Non-3GPP networks have it is multiple, in packet loss
Make less than in the Non-3GPP networks of Second Threshold, selecting network delay to be less than the Non-3GPP networks of the 3rd threshold value (such as 50ms)
To specify Non-3GPP networks, if the Non-3GPP networks that network delay is less than the 3rd threshold value have multiple, history is selected to cut
Non-3GPP network of the power more than the 4th threshold value (such as 95%) is changed into as specified Non-3GPP networks.
Step S240, the information of specified Non-3GPP networks is sent to the user equipment.
