Abstract: In a handover procedure of a wireless communication device (100), a source base station (110) of the handover sends a message to the wireless communication device (100). The message indicates authorization of a handover of the wireless communication device from the source base station to at least one candidate base station (120, 130), which is prepared to act as a target base station of the handover. Further, the source base station (110) instructs the wireless communication device (100) to send at least one uplink signal. The source base station (110) receives at least one report of a measurement performed by the at least one candidate base station (120, 130) on the at least one uplink signal. Based on the at least one measurement, the source base station (110) controls the handover.

Abstract: Method for providing a count indication of radio devices to a radio network, particularly in idle or in-active mode, comprising transmitting a presence message to a first base station of the radio network based on a reporting rule, which presence message indicates presence of a radio device within a dedicated coverage area of the radio network. The reporting rule may include a probability rule, wherein said presence message is transmitted from the radio device responsive to an outcome of a probability check, based on the probability rule, indicating that the radio device shall transmit the presence message. The reporting rule may also be transmitted responsive to the radio device making a cell reselection to the first cell. After receiving an acknowledgement presence message from the base station, connection setup to the network is terminated.

Abstract: Apparatus, systems, and methods provide for the cellular network to indicate preferences for controlling/regulating the background data traffic. Specifically, the network communicates a message to UEs that request that the UEs control background data transmissions. In response to the UEs receiving the message, the UEs reconfigure to control background date transmissions, such as controlling the volume of background data transmissions (e.g., reducing the volume of background data transmissions or the like). In specific embodiments the UE reconfigures by queuing background data and subsequently transmitting the queued background data at time intervals. As a result of such background data traffic control, the network experiences less radio traffic and problems related to cell overloading can be mitigated.
