A wireless communication system includes a first base station device, a second base station device, a mobile station device configured to communicate with the first base station device using a first component carrier and to communicate with the second base station device using a second component carrier. The first base station device includes a disconnection preparation requesting unit configured to transmit to the second base station device, a disconnection preparation request that requests the second base station device to prepare to disconnect the second component carrier.

Some demonstrative embodiments include apparatuses, systems and/or methods of tearing down a Protocol Adaptation Layer (PAL) session. For example, an apparatus may include a first PAL communication unit to control a PAL connection, over a PAL, between a first device and a second device, the first PAL communication unit is to control the PAL connection during a session with a second PAL communication unit over a communication link, wherein the first PAL communication unit is to tear down the session according to a tear down procedure.

A communication device, user equipment, and a communication system are provided. The communication device comprises a Context ID check module to check a Context ID (CID) of a current default bearer in response to a disconnect command from a host; wherein, if the Context ID check module determines that there is only a first default bearer activated, the Context ID check module releases the connection between the communication device and the host without deactivating the first default bearer; and if the Context ID check module determines that there are two default bearers activated, the Context ID check module releases the second default bearer.

Provided are a method and apparatus for managing a beacon device. More particularly, a beacon management server is connected with the beacon device through a communication network and configured to periodically updates and manages a valid period of the beacon device. The beacon device initializes itself by autonomously deleting beacon information stored therein when the beacon device has been disconnected from the beacon management server for a certain time or more. Thus, the beacon device may be managed through the beacon management server. An operation of the beacon device may be controlled even when the beacon device is lost, thereby preventing illegal use of the beacon device by controlling a beacon signal that is transmitted even after the beacon device is lost. In addition, the beacon management server may verify the validity of the beacon device to give security to the beacon device and periodically update the valid period, thereby allowing efficient use of the beacon device.

A method by a near-field communication (NFC) device is described. The method includes receiving, at an NFC controller, an end of test response from a lower tester (LT) device that indicates completion by the LT device of an NFC Forum test case. The method also includes sending an end of test message from the NFC controller to a device host. The method further includes initiating, by the device host, a deactivation process for the LT device upon receiving the end of test message.

Disclosed is a method for controlling a security mode by a user equipment (UE) in a wireless communication system, including performing a camp-on process and a cell update process with a network when an out-of-service (OOS) situation has occurred, receiving one of a signaling connection release (SCR) message and a first protocol data unit (PDU) which corresponds to the SCR message from the network, receiving a security mode command (SMC) message from the network if the SCR message is received, performing an integrity process on the SCR message using an old security configuration, and performing a rollback process to discard a new security configuration included in the SMC message if a result of the integrity process result an integrity check success, and updating a security configuration to the old security configuration.

A communication apparatus includes a communication unit configured to communicate with an external apparatus, and a control unit having a plurality of display modes including a single-display mode of displaying a single content on a single screen of a display unit, and a multi-display mode of displaying a plurality of contents on the single screen of the display unit, wherein, if the communication unit starts communication with the external apparatus in a state where the display mode is the multi-display mode, the control unit displays the plurality of contents on the single screen of the display unit and receives a selection of a transmission target after establishment of the communication with the external apparatus, and wherein, if the communication unit starts the communication with the external apparatus in a state where the display mode is the single-display mode, the control unit does not receive the selection of the transmission target after the establishment of the communication with the external apparatus.

A communication device includes: a communication unit that performs communication with another communication device in a first range through a first communication scheme; and a detecting unit that detects prescribed information within a second range different from the first range. When the detecting unit detects the prescribed information, the communication unit performs communication with the other communication device within the second range through the first communication scheme.

An apparatus and method are provided. The method includes receiving, at an electronic device including a first processor and a second processor, using the first processor, a connection request via a network, and refraining from transmitting the connection request from the first processor to the second processor based at least in part on a determination that the second processor is in a sleep state, and that the connection request is associated with data set as unallowable by the second processor.

A method for managing congestion on a communication network that includes a network node having a congestion level. Congestion pre-emption criteria corresponding to the congestion level is determined. A list of potential service pre-emption candidates associated with a service pre-emption criteria that is at least equal to the congestion pre-emption criteria is created. The list of potential service pre-emption candidates is at least a sub-set of a plurality of services on the node. A determination is made as to whether to pre-empt at least one of the potential service pre-emption candidates on the list based at least on the service pre-emption criteria.
