A second device that is in communication with a first device receives transmissions of the first device and detects a SILENCE period status of the first device, which corresponds to a status wherein the first device has no speech samples to be transmitted towards the second apparatus. The second device determines the type of the received transmissions, counts the number of received transmissions of a first type, and times a time interval between the last received transmission of the first type and the last received transmission of a second determined type. At reception of a transmission of the first type, the second device detects whether the first device is in the SILENCE period status on an evaluation of the counted number of transmissions of the first type and the time interval of the last received transmission of the first type and the last received transmission of the second type.

Method, system and device for detecting a silence period status in a user equipment

It is presented a method for releasing semi-persistent scheduling, SPS, for a wireless device. The method is performed in a network node and comprising the steps of: transmitting an SPS release message to the wireless device to release uplink SPS; starting a timer; when a first condition is true, transmitting a grant for uplink transmission to the wireless device, the first condition being true when the timer expires and/or a scheduling request has been received from the wireless device; receiving a data type indication from the wireless device; and determining that an SPS release message has been correctly received by the wireless device when a scheduling request has been received from the wireless device, the grant has been transmitted and the data type indication indicates only voice over internet protocol, VoIP, data from the wireless device.

Release of semi-persistent scheduling

A method, system and device for detecting a SILENCE period statusA in a first device The detection is performed by a second devicethat is in communication with the first device, receiving transmissions of the first device. The SILENCE period status corresponds to a status wherein the first device has no speech samples to be transmitted towards the second apparatus. The second device receives,, transmissions from the first device and determines,A,B,C, the type of the received transmissions. The second device countsthe number of received transmissions of a first type, and times a time interval between the last received transmission of the first type and the last received transmission of a second determined type. At reception of a transmission of the first type, the second device detectswhether the first device is in the SILENCE period statuson an evaluationof the counted number of transmissions of the first type and the time interval of the last received transmission of the first type and the last received transmission of the second type based on thresholds with a logical expression.
