Mobile-satellite terminal is stated according to the pilot signal strength of described instruction infomation detection object beam, and feeds back the object beam
Pilot signal strength；
Signal strength receiving module is strong for receiving the pilot signal of the object beam of the mobile-satellite terminal feedback
Degree, when detecting that the pilot signal strength of the object beam meets pre-set level requirement, Xiang Suoshu mobile-satellite terminal hair
Indication message is sent, so that the mobile-satellite terminal disconnects the communication with current beam according to the indication message
Connection.
8. juncture station according to claim 7, which is characterized in that the signal strength receiving module is used for:
It is greater than predetermined threshold value, and the pilot signal of the object beam in the pilot signal strength for detecting the object beam
When the difference of intensity and the predetermined threshold value is greater than hysteresis margin, Xiang Suoshu mobile-satellite terminal sends indication message.
