Abstract

Methods and systems are described for individual and group paging of a wireless device via a wireless communications network. The method can include setting a paging cycle and a paging offset for the wireless device. A wireless device can be assigned to a device group using a device group identifier. The wireless device can wake up to check for paging events received via the wireless communication network during a portion of the paging cycle. A further operation can be receiving a group paging event for the device group at the wireless device during the portion of the paging cycle.
