Positional information receiver module, for receiving the positional information that mobile ICBM SHF satellite terminal sends, when detecting that described mobile ICBM SHF satellite terminal arrives switching position, instruction information is sent to described mobile ICBM SHF satellite terminal, so that described mobile ICBM SHF satellite terminal detects the pilot signal strength of target wave beam according to described instruction information, and feed back the pilot signal strength of described target wave beam;
Strength of signal receiver module, for receiving the pilot signal strength of the described target wave beam of described mobile ICBM SHF satellite terminal feedback, detect the pilot signal strength of described target wave beam meet pre-set level require time, indication message is sent, so that described mobile ICBM SHF satellite terminal disconnects the communication connection with current wave beam according to described indication message to described mobile ICBM SHF satellite terminal.
8. juncture station according to claim 7, it is characterised in that, described strength of signal receiver module is used for:
Detecting that the pilot signal strength of described target wave beam is greater than predetermined threshold value, and when the difference of the pilot signal strength of described target wave beam and described predetermined threshold value is greater than hysteresis margin, sending indication message to described mobile ICBM SHF satellite terminal.
