Title:
DIGITAL CORDLESS TELEPHONE SET
Document Type and Number:
Japanese Patent JP3133513
Kind Code:
B2
Abstract:
PURPOSE: To improve the convenience of use by providing a reception data storage means and a frame structure recognition means with the telephone set and registering preferentially the position of a slave set when the recognized frame structure differs from the stored frame structure.
CONSTITUTION: All control is implemented by a microcomputer 6 and at first a PLL frequency synthesizer 10 or the like is initialized. Then control data and control channel information are received, the frame structure on a control channel is recognized and stored in a storage device 13. Since each master station has a proper frame structure, the frame structure is naturally changed when the mobile set enters a zone of other master set by movement or the like. When the change in the frame structure is recognized in the intermittent reception, whether or not the cause comes from position registration is checked. When the cause results from the position registration, the processing of the position registration is implemented, when the processing is finished, the service channel and the link channel are succeedingly cut off and an idle state is set.
