Document Type and Number:
WIPO Patent Application WO/2020/007039
Kind Code:
A1
Abstract:
Provided are a method and device supporting networking and in-call functions of mobile phones employing a satellite mobile communication hotspot. In the invention, extension numbers are assigned to mobile phones networked by means of a satellite mobile communication hotspot, and DTMF signal parameter tables of different terrestrial networks are established. A DTMF encoding/decoding technique is employed to obtain a corresponding extension address, and matching of a called terminal is performed during a call according to extension number information, thereby realizing in-call functions of multiple mobile phones networked by means of a satellite mobile communication hotspot, and expanding an application range of a satellite mobile communication hotspot.
