Problems solved by technology

[0005] In particular, in the case where payload data is associated with a service implemented by the cellular network and the terminal, where the service has a Quality of Service (QoS) requirement corresponding to a certain latency, meeting this QoS requirement can be difficult
For example, latency to deliver payload data can be affected by the periodicity of DRX

Embodiment Construction

[0042] In the following, concepts according to exemplary embodiments of the present invention will be explained in more detail with reference to the drawings. The illustrated embodiments relate to techniques for controlling the implementation of a discontinuous reception cycle, and in particular to determining the duration of an active period of a discontinuous reception cycle for implementation by a terminal connected to a cellular network .

[0043] In the example shown, monitoring the radio link between the cellular network and the terminal for the reception of a second message (triggered by a first message previously transmitted to the terminal) is used as all for the duration of the active period. definite criteria for judging. Specifically, the first message triggers the terminal to transmit the second message at the associated transmission interval.

[0044] In some examples, the radio link is monitored for failed reception of the second message. Sometimes, the situa...

Abstract

A first message (391) is transmitted via a radio link of a cellular network to a terminal. The first message (391) triggers the terminal to transmit a second message (392) via the radio link at the associated transmission interval. The radio link is monitored for reception of the second message (392) at the associated transmission interval. Based on said monitoring, the duration (355) of an activeperiod (305) of the discontinuous reception cycle (301) to be implemented by the terminal is determined.

Description

technical field [0001] Various embodiments relate to determining a duration of an active period of a discontinuous reception cycle to be implemented by a terminal and a corresponding network node of a cellular network. In particular, various embodiments relate to techniques for determining the duration of an active period based on monitoring a radio link of a cellular network for receipt of a previously triggered message. Background technique [0002] Mobile communications over cellular networks are an essential part of modern life. As more and more terminals are connected to cellular networks, reducing the power consumption of the terminals has become a major requirement. [0003] Techniques are known to reduce the power consumption of terminals by enabling discontinuous reception of messages transmitted by a cellular network via a radio link of the cellular network. One example of implementing discontinuous reception is the discontinuous reception cycle (DRX) according t...
