摘要:
The invention relates to method applicable in a packet-switched cellular network for voice connections, by which method a new dedicated channel can be established quickly using the existing dedicated channel of the voice connection. The establishment of the new dedicated channel utilizes the previous dedicated channel the existence of which is extended by sending to at least the receiving terminals post-speech packets according to the invention. The post-speech packets produce a 2-second delay, approximately, which is sufficient to establish a new dedicated channel between terminals participating in a session.

The invention relates to a method of indicating about an incoming connection and a radio terminal equipment arrangement comprising: a cellular core unit comprising: a control unit; and one or more peripheral units. The control unit is configured to indicate the incoming connection in one or more peripheral units but not in the cellular core unit, when the LPRF connection between the cellular core unit and the peripheral unit is available; and to indicate the incoming connection in the cellular core unit, when the LPRF connection between the cellular core unit and the peripheral unit is not available and to indicate the incoming connection in the peripheral unit, when the LPRF connection between the cellular core unit and the peripheral unit becomes available.
摘要:
A data transmission method between at least two mobile communication devices is provided, a communication device comprising a first and a second transceiver. The first transceiver communicates with a transceiver of another device with a data rate higher than that of the second transceiver, and the second transceiver communicates with a transceiver of another device with power consumption level lower than that of the first transceiver. The device is configured to communicate with another communication device using the first transceiver when data is to be transmitted between devices; stop using the first transceiver when data transmission ceases, and communicate with another communication device using the second transceiver to set up the use of first transceiver when a need to send data arises.
摘要:
There is provided a method of saving power and a radio terminal equipment arrangement comprising a cellular core unit and at least one peripheral unit. The peripheral unit comprises a control unit for controlling the functions of the peripheral unit, and a transceiver for sending a message for requesting cellular related information to the cellular core unit when an application requiring a cellular connection is activated by the peripheral unit. The cellular core unit is configured to send cellular related information to the peripheral unit when the message for requesting cellular related information has been received, and the control unit for controlling functions of the peripheral unit is configured to notify cellular related information in the peripheral unit based on the received cellular related information from the cellular core unit.
摘要:
A method is disclosed for operating a wireless TDMA communications system. The method includes steps of monitoring a propagation delay of a mobile station; and when the propagation delay exceeds a predetermined limit, changing by a time slot unit a value of one or both of Tta1 and Ttb1, wherein Tta1 is a minimum number of time slots allowed between the end of a last, previous receive time slot and a first, next transmit time slot, when a channel measurement is to be performed in between, and wherein Ttb1 is a minimum number of time slots allowed between the end of a last, previous receive time slot and a first, next transmit time slot.
