Transfer control point, mobile telephone fixed terminal and switch capable of being used in a device for connecting a telephone switch located in an isolated community to a fixed telephone network

摘要

The system connects a fixed telephone network (PSTN) to a telephone switch (SW) in an isolated region via a mobile telephone network (PLMN) of a type derived from the GSM type, and including at least one satellite (S), a plurality of fixed user terminals (UT1, . . . , UT100) being connected to that telephone switch. The system includes a plurality of fixed mobile telephone terminals (RTa, . . . , RTn) and a transfer control point (TCP) connecting the fixed network (PSTN) to a mobile services switching center (MSC) to manage dynamically allocation of trunks (Ca, Cb, . . . , Cn) supported by those fixed mobile telephone terminals (RTa, . . . RTn) to telephone calls setup between the fixed telephone network (PSTN) and the user terminals (UT1, . . . , UT100) in the isolated region.
