Abstract
There is provided, for example, a method, comprising: transmitting, by a wireless device, a data accumulation request to an access node of a wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data; receiving a message from the access node, wherein the message indicates that there is downlink data in the access node for the wireless device; and triggering a service period for receiving the downlink data from the access node upon determining, on the basis of the received message, that the downlink data satisfies the at least one downlink accumulation rule.
Claims16
A method, comprising:
- transmitting, by a wireless device, a data accumulation request to an access node of a wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data, and the at least one downlink accumulation rule comprises at least one parameter of the following parameters:
- a minimum transmission unit for downlink data transmission and a minimum duration for buffering data for downlink data transmission;
- receiving a message from the access node, wherein the message comprises a traffic indication map which indicates whether there is downlink data satisfying the at least one downlink accumulation rule in the access node for the wireless device;
- and
- upon detecting that there is downlink data satisfying the at least one downlink accumulation rule in the access node, triggering a service period for receiving the downlink data from the access node.

A method, comprising:
- receiving, by an access node of a wireless network, a data accumulation request from a wireless device, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data, and the at least one downlink accumulation rule comprises at least one parameter of the following parameters:
- a minimum transmission unit for downlink data transmission and a minimum duration for buffering data for downlink data transmission;
- transmitting a message to the wireless device upon determining that the at least one downlink accumulation rule is met, wherein the message comprises a traffic indication map which indicates whether there is downlink data satisfying the at least one downlink accumulation rule in the access node for the wireless device in order to allow the wireless device to detect that there is downlink data satisfying the at least one downlink accumulation rule in the access node and trigger a service period for receiving the downlink data;
- and
- transmitting the downlink data to the wireless device upon detecting that the wireless device has triggered the service period.
2 more elements
An apparatus, comprising:
- at least one processor and at least one non-transitory memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
- cause a wireless device of a wireless network to transmit a data accumulation request to an access node of the wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data, and the at least one downlink accumulation rule comprises at least one parameter of the following parameters:
- a minimum transmission unit for downlink data transmission and a minimum duration for buffering data for downlink data transmission;
- cause the wireless device to receive a message from the access node, wherein the message comprises a traffic indication map which indicates whether there is downlink data satisfying the at least one downlink accumulation rule in the access node for the wireless device;
- and
- upon detecting that there is downlink data satisfying the at least one downlink accumulation rule in the access node, trigger a service period for receiving the downlink data from the access node upon determining.

An apparatus, comprising:
- at least one processor and at least one non-transitory memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
- cause an access node of a wireless network to receive a data accumulation request from a wireless device of the wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data, and the at least one downlink accumulation rule comprises at least one parameter of the following parameters:
- a minimum transmission unit for downlink data transmission and a minimum duration for buffering data for downlink data transmission;
- cause the access node to transmit a message to the wireless device upon determining that the at least one downlink accumulation rule is met, wherein the message comprises a traffic indication map which indicates whether there is downlink data satisfying the at least one downlink accumulation rule in the access node for the wireless device in order to allow the wireless device to detect that there is downlink data satisfying the at least one downlink accumulation rule in the access node and trigger a service period for receiving the downlink data;
- and
- cause the access node to transmit the downlink data to the wireless device upon detecting that the wireless device has triggered the service period.
