Abstract

The invention includes the steps of: (1) during the 0^th frame, setting value of an extend flag of zero length paging message through P-channel to be 1 for informing the portable terminal to receive the paging message within the 2^nd frame; (2) during the frames of a first-type following the 2^nd frame, via a data/voice field, broadcasting the information to the portable terminal.

Claims

1. A method for providing voice/data and information communication in a DECT radio communication system, said DECT radio communication system comprising at least a base station and a portable terminal, said DECT radio communication system comprising M frequency channels, each channel comprising N time slots, said base station transmitting signal data to said portable terminal through multiple frames, a data format corresponding to each time slot comprising a preamble field, a synchronization field, a protocol related signal field and a data/voice field, said multiple frames comprising a first-type frame for transmitting a P-channel data and a N-channel data, said P-channel data being used for media access control paging, said first-type frame comprising a 0^th, a 2^nd, a 4^th, a 6^th, a 10^th, a 12^th frame, the method comprising the steps of:

(1) during the 0^th frame, setting value of an extend flag of zero length paging message through P-channel to be 1 for informing said portable terminal to receive the paging message within the 2^nd frame;

(2) during the frames of a first-type following the 2^nd frame, via a data/voice field, broadcasting the information to said portable terminal.

2. The method of claim 1, the step (2) comprising the steps of:

during the 2^nd frame, transmitting a zero length paging data for informing said portable terminal to consecutively receive one paging message within the 4^th frame and said portable terminal preparing to receive a message in the data/voice field.

3. The method of claim 2, the step (2) further comprising:

during the 4^th frame, writing information to a downlink data buffer and changing value of a data/voice field pointer buffer in said time slot to point towards said downlink data buffer for broadcasting information, and informing the portable terminal selectively preparing to receive next paging message or finish broadcast process during the 6^th frame.

4. The method of claim 3, the step (2) further comprising:

during the 5^th frame, changing value of said data/voice field pointer buffer in said time slot to point towards a voice or a data buffer for transmitting said voice or data.

5. The method of claim 4, the step (2) further comprising:

during the 6^th frame, writing information into said downlink data buffer, changing value of said voice/data field pointer buffer in said time slot to point towards said downlink data buffer for transmitting information, and informing the portable terminal selectively preparing to receive next paging message or finish broadcast process during the 10^th frame.

6. A method for providing voice/data and information communication in a DECT radio communication system, said DECT radio communication system comprising at least a base station and a portable terminal, said DECT radio communication system comprising M frequency channels, each channel comprising N time slots, said base station transmitting signal data to the portable terminal through multiple frames, a data format corresponding to each time slot comprising a preamble field, a synchronization field, a protocol related signal field and a data/voice field, said multiple frames comprising a first-type frame and a second-type frame, said first-type frame transmitting a P-channel data and a N-channel data, said P-channel data being used for media access control paging, said first-type frame comprising a 0^th, a 2^nd, a 4^th, a 6^th, a 10^th, a 12^th frame, the method comprising the steps of:

(1) during the 0^th frame, setting value of an extend flag of zero length paging message through P-channel to be 1 for informing said portable terminal to receive the paging message within the 2^nd frame;

(2) during the frames of the first-type frame following the 2^nd frame, via a data/voice field, broadcasting the information to said portable terminal in sequence, and at same time broadcasting a voice data of a preceding frame allowing said portable terminal to receive continuous voice signal.

7. The method of claim 6, further comprising:

(3) during the second-type frame, changing value of a data/voice field pointer buffer in said time slot to point towards a voice buffer for immediately transmitting a connected real-time voice signal.
