In the terminal device of mode and land mobile mode, typically, it can integrate in mobile phone, this method specifically includes as follows
Step:
The concurrent type of S110, the communication supported according to terminal, from presetting multiple alternative baseband signals
The baseband signal processing unit with the concurrent type matching is gated in processing unit, wherein the concurrent type includes: satellite
Communication mode is concurrent with land mobile mode.
Concurrently, refer in a period that several programs are run between operation finishes all in having been turned on, and these
Program is all to run on the same processor, but only one program is run on treaters in any one moment point.In nothing
In line communication mode, concurrently it is different wireless signal while carries out data transmission；For example, terminal device can by satellite with
Marine ICBM SHF satellite terminal carries out data interaction, while can be counted by other of land mobile communication system and ground terminal
According to interaction.Particularly, so-called is simultaneously that the data since data interaction speed is exceedingly fast, on user's sense organ are synchronous, the side of execution
Formula still remains sequencing.
