Abstract: A method is disclosed of switching the active subscriber identity of a communication terminal which is capable at each moment in time of having only one active subscriber identity. An active subscriber identity switch from a first subscriber identity to a second subscriber identity is initiated. At least one parameter associated with a time of expiry of a timer associated with the first subscriber identity is stored. The first subscriber identity is deactivated and the second subscriber identity is activated. If an active subscriber identity switch from the second subscriber identity to the first subscriber identity is initiated and the first subscriber identity is activated, it may be determined whether the time of expiry of the timer associated with the first subscriber identity has passed. Network registration of the first subscriber identity may be performed only if the time of expiry of the timer associated with the first subscriber identity has passed.

Abstract: According to an embodiment, a method of estimating a distance to a wireless access point in an indoor environment using a signal propagation model begins with the receipt of a first received signal strength value based on a signal received at a first device from a wireless access point in the indoor environment. Based on a predetermined characteristic of the indoor environment, an estimate is made that the received signal originated from a first distance from the first device. A signal propagation characteristic is estimated based on the first signal strength and the estimated first distance and a plurality of signal samples are received from a plurality of devices. Finally, a signal propagation model for the indoor environment is created based on the signal propagation characteristic and the signal samples, and a distance to any wireless access point in the indoor environment is estimated based on the signal propagation model.

Abstract: A smartphone includes: a first communication processing unit that performs wireless communication by a WiMAX network; a second communication processing unit that performs communication with an external device; a touch-screen display; and a controller. In a state of searching for WiMAX, in a case in which a power supply of the touch-screen display is turned off and communication with the external device by the second communication processing unit is disconnected, the controller causes the first communication processing unit to stop searching for WiMAX.

Abstract: A device management (DM) server. The server comprises a memory, a processor, and an application programming interface (API), wherein the secondary DM server makes available a subset of the functionality of a DM server and when accessed through a portal, initiates a DM session with a short message service (SMS) system type message, notifies the mobile communication devices associated with a trusted third party of secondary DM server via the short message service system type message, and makes available firmware to be downloaded from a sandbox of the secondary DM server and tested by a limited number of the mobile communication devices associated with the third party, wherein the sandbox is an area in a memory to isolate untested firmware or firmware under test from the environment outside the sandbox.

Abstract: A method, apparatus and computer program product are provided that may provide a scheme for measurement reporting for minimization of drive tests (MDT) data. In the context of a method, an indication of a handover of a user terminal from a first cell associated with a first public land mobile network (PLMN) to a second cell associated with a second PLMN may be received by the user terminal. Responsive to the handover, an indication of availability of MDT measurement logged data may be provided to the second PLMN. A determination may then be made at the user terminal as to whether to provide the MDT measurement logged data to the second PLMN based on an identity of the second PLMN.

Abstract: The present invention relates to a wireless communication system. In particular, the present invention relates to a method for a terminal to measure a signal in a wireless communication system and a device therefor, and comprises: a step for receiving information on a first specific time interval from a first cell after having set the connection with the first cell; a step for receiving a second cell signal through the first specific time interval on the basis of the information; a step for informing the first cell the proximity of a second cell in case the terminal is a member of the second cell; and a step for receiving the second cell signal without basing on the information on the first specific time interval, after informing the first cell of the proximity of the second cell.

Abstract: The present invention relates to a wireless communication system. Particularly, the present invention relates to a method and a device for reporting channel state information, the method comprising the steps of: carrying out operations for periodic reporting of a first channel state information item; and carrying out operations for periodic reporting of a second channel state information item, wherein the period for reporting the first channel state information item is longer than the period for reporting the second channel state information item, and the second channel state information item is determined on the basis of the first channel state information item.

Abstract: A request to establish a call involving a wireless communication device WCD served by a radio access network (RAN) may be received. The WCD may receive signals from the RAN via a plurality of wireless coverage areas at respective signal strengths. The plurality of wireless coverage areas may be defined by the RAN. A media codec to use for the call may be determined. Based on the media codec, a set of n wireless coverage areas through which the WCD and the RAN communicate during the call may be selected. The value of n may be between 1 and a predetermined maximum number, and the set of n wireless coverage areas may be selected from the plurality of wireless coverage areas.

Abstract: Disclosed techniques limit or reduce the amount of data for which a subscriber may be charged that may not actually be received at the subscriber's mobile device. A counter may be started when a node has data to be delivered to a mobile device. The node may send the data through a radio access network for delivery to the mobile device and record an amount of the data sent for the mobile device through the radio access network for data usage billing purposes while running the counter, until the counter reaches a predetermined value. When the counter reaches the predetermined value, if no traffic channel has been set up with the mobile device, the node will stop recording the amount of the data sent for the mobile device through the radio access network for data usage billing purposes.
