Abstract

A process, a control center, and a terminal device are proposed for transmitting messages to terminal devices in a, in particular, wireless, telecommunications system with a control center and with terminal devices. The transmission protocol is frame structured in the time domain. In the transmission protocol, the terminal devices ignore messages from the control center during a single frame, or several consecutive frames. The following steps are carried out in order to transmit a message to one terminal device or to a plurality of terminal devices: First, a number of terminal device groups which includes the majority of the terminal devices are formed by the control center. Each terminal device belongs to exactly one terminal device group and all terminal devices of a terminal device group are ready to receive messages during the same frame. Second, the message that is to be sent is transmitted to each of at least one terminal device group during one possible frame.

Claims21

Dependent claims

A process for transmitting messages to a plurality of terminal devices in a telecommunications system having a control center that uses a protocol that is frame-structured in a time domain, comprising the steps of:

causing the control center to transmit a message to the terminal devices in a first segment within a plurality of frames by performing the steps of:
combining a group of the terminal devices into at least one terminal device group, a number of the at least one terminal device group being formed by a majority of the terminal devices, each of the terminal devices belonging to only one of the at least one terminal device group,
preparing all of the terminal devices of one of the at least one terminal device group to receive messages from the control center during a single frame, all of the terminal devices of the one of the at least one terminal device group ignoring messages from the control center during a frame other than the single frame, and preparing the terminal devices of the remaining of the at least one terminal device group to receive messages during a frame other than the single frame, the terminal devices of the remaining of the at least one terminal device group ignoring messages from the control center during the single frame, and
for each of the at least one terminal device group if there is a message to be transmitted, transmitting the message to be transmitted to all of the terminal devices of the one of the at least one terminal device group only during the single frame and transmitting the message to be transmitted to the terminal devices of the remaining of the at least one terminal device group only during the frame other than the single frame;
and
causing the control center to receive a message from the terminal devices in a second segment within the frames, the terminal devices ignoring the message transmitted by the control center during one of a single frame and successive frames.

3 more elements

A control center for transmitting messages to a plurality of terminal devices in a telecommunications system, comprising:

an arrangement for transmitting a message to the terminal devices in a first segment within a plurality of frames, the arrangement for transmitting including:
an arrangement for combining a group of the terminal devices into at least one terminal device group, a number of the at least one terminal device group being formed by a majority of the terminal devices, each of the terminal devices belonging to only one of the at least one terminal device group,
an arrangement for preparing all of the terminal devices of one of the at least one terminal device group to receive messages from the control center during a single frame, all of the terminal devices of the one of the at least one terminal device group ignoring messages from the control center during a frame other than the single frame, and preparing the terminal devices of the remaining of the at least one terminal device group to receive messages during a frame other than the single frame, the terminal devices of the remaining of the at least one terminal device group ignoring messages from the control center during the single frame, and
an arrangement for transmitting, if there is a message to be transmitted for each of the at least one terminal device group, the message to be transmitted to all of the terminal devices of the one of the at least one terminal device group only during a possible the single frame and transmitting the message to be transmitted to the terminal devices of the remaining of the at least one terminal device group only during the frame other than the single frame;
an arrangement for receiving a message from the terminal devices in a second segment within the frames, the terminal devices ignoring the message transmitted by the control center during one of a single frame and successive frames;
a multiple-recipient message controller that handles messages to be sent to several terminal devices assigned to the control center;
a message storage unit;
and
a controller for implementing power saving measures.
