Sony patents satellite handoff that skips connection steps
Sony describes a method for devices to switch between low-earth orbit satellites without using a standard random access procedure. The device receives specific switching information from the current satellite in advance, allowing it to connect to the next satellite more directly.
In the filing’s own words
A communication device is connected to a first non-geostationary satellite station among a plurality of non-geostationary satellite stations forming a cell positionally fixed on ground. The communication device includes an acquisition section configured to acquire, from the first non-geostationary satellite station in advance before switching processing, information related to switching of connection from the first non-geostationary satellite station to a second non-geostationary satellite station among the plurality of non-geostationary satellite stations, and a switching processing section configured to switch the connection from the first non-geostationary satellite station to the second non-geostationary satellite station without a random access procedure, based on the information related to switching of the connection.
What exactly they claim (claim 1)
1. A communication device connected to a first non-geostationary satellite station among a plurality of non-geostationary satellite stations forming a cell positionally fixed on ground, the communication device comprising: an acquisition section configured to acquire, from the first non-geostationary satellite station in advance before switching processing, information related to switching of connection from the first non-geostationary satellite station to a second non-geostationary satellite station among the plurality of non-geostationary satellite stations; and a switching processing section configured to switch the connection from the first non-geostationary satellite station to the second non-geostationary satellite station without a random access procedure, based on the information related to switching of the connection.
