Systems, methods and computer-readable media are obtaining location updates of a tracking device via peer to peer communication with other nearby devices where obtaining such update is otherwise not possible. In one aspect, a method includes receiving, at a device, a first location update from a network component; determining, by the device, if a triggering condition is met for determining a second location update; activating, by the device, device-to-device communication for receiving the second location update from nearby devices in vicinity of the device when the triggering condition is met receiving the second location update from at least one of the nearby devices via the device-to-device communication; and sending the second location update to a server for the server to determine an arrival alert for alerting a destination of an amount of time remaining until the device reaches the destination.

As a result of ISR being enabled between a portable terminal device and a network which are capable of communicating by using the communication protocols of a plurality of wireless access technologies, the portable terminal device-performs position registration processing between the plurality of wireless access technologies and the portable terminal device each time a fixed period of time elapses, and the portable terminal device is able to move between the plurality of wireless access technologies that have already been registered, without conducting new position registration processing. At this time, if there is a possibility of there being a difference in ISR states (activated or not activated) between the portable terminal device and the network, the portable terminal device ignores any instructions issued by the network for ISR to be enabled in the portable terminal device.

Embodiments described herein provide methods and apparatus for determining a radio access network notification area, RNA, in a wireless communications network. A method in a wireless device comprises receiving an indication of the RNA, wherein the indication comprises a public land mobile network code, PLMN associated with a plurality of tracking area codes, TACs; and determining based on the RNA indication, a plurality of tracking area identifiers comprising each of the plurality of TACs and their associated PLMN.

A wireless communications system operating in a coverage area of a wireless network includes a radiofrequency (RF) front end and a base station coupled to the RF front end, the base station receiving signals data from received transmissions from wireless devices; and a non-transitory computer readable storage medium having encoded thereon a program of machine instructions executable by a processor in signal communication with the base station. The processor executes the instructions to receive from the base station, the received signals data, process the received signals data to determine a characteristic of the wireless device, determine, based on the characteristic, whether the wireless device is allowed to continue transmissions in the wireless network, controlling the base station to lock the wireless device to the base station when continued transmissions are not allowed, and redirecting the wireless device to attempt access to the wireless network when continued transmissions are allowed.
