Abstract
According to an embodiment, a method for use in a wireless device is provided. The method comprises waking up from a discontinuous reception (DRX) mode in a cell. The method further comprises determining whether the cell is the same as a previous cell of the wireless device. In response to determining that the cell is not the same as the previous cell, the method further comprises determining whether the wireless device missed a wake-up signal opportunity in the cell. The method further comprises monitoring each of the paging occasions associated with the wake-up signal opportunity if the cell is not the same as the previous cell and the wake-up signal opportunity was missed.
Claims11
A method for use in a network node, comprising:
- determining whether a previous cell of the wireless device belongs to the network node;
- upon determining that the previous cell of the wireless device belongs to the network node, paging the wireless device using a wake-up signal;
- and
- upon determining that the previous cell of the wireless device does not belong to the network node, paging the wireless device without using a wake-up signal.
A network node comprising memory operable to store instructions and processing circuitry operable to execute the instructions, whereby the network node is operable to:
- determine whether a previous cell of the wireless device belongs to the network node;
- upon determining that the previous cell of the wireless device belongs to the network node, page the wireless device using a wake-up signal;
- and
- upon determining that the previous cell of the wireless device does not belong to the network node, page the wireless device without using a wake-up signal.
A computer program product comprising a non-transitory computer readable medium storing computer readable program code, the computer readable program code comprises:
- program code for determining whether a previous cell of the wireless device belongs to the network node;
- program code for, upon determining that the previous cell of the wireless device belongs to the network node, paging the wireless device using a wake-up signal;
- and
- program code for, upon determining that the previous cell of the wireless device does not belong to the network node, paging the wireless device without using a wake-up signal.
