Abstract: A method for reporting information of device to device communication, user equipment and a base station. The method for reporting information includes: transmitting, by UE to a base station, indication information indicating power preference of different communication links, the communication links comprising a D2D communication link between the UE and other UE, and/or a cellular communication link between the UE and the base station. The network side may provide corresponding configuration regarding properties of services of different communication links according to the indication information, thereby controlling the power consumption of the UE more efficiently.

Abstract: An information reporting method for device to device communication, user equipment and base station. The method includes: transmitting, by UE, indication information indicating to perform D2D-only communication, so that a base station learns that a data traffic of the UE is a D2D-only communication traffic. The base station may learn D2D-only information of the UE, so as to suitably configure the UE, thereby avoiding unnecessary handover or mode selection.

Abstract: An apparatus for reporting connection setup request, includes a request transmitting unit configured to transmit a connection setup request for device-to-device communication to a network side when it is determined according to pre-obtained configuration information that the connection setup request for device-to-device communication can be transmitted to the network side.

Abstract: A chip card holder includes a housing, a receiving frame, a tray, and a pin. The housing defines a latching groove. The receiving frame is mounted to the housing, and the receiving frame includes at least one ejecting arm. The tray is slidably received in the receiving frame and defines a receiving groove configured for receiving a chip card. The tray includes a latching tongue. When the tray is received in the receiving frame, the latching tongue is latched in the latching groove, and the ejecting arm abuts against one end of the tray. The pin deforms the latching tongue to unlock the tray from the housing.

Abstract: A holder for a surface contact card includes a housing, a tray for receiving the surface contact card, and an ejecting mechanism including a locking block and a first elastic member. The housing includes a base defining a receiving recess. The tray is slidably received in the receiving recess. The locking block releasably locks the tray in the receiving recess. The first elastic member flexibly resists the insertion of the tray into the housing. When the locking block is pushed by an outside force to release the locking by the locking block, the tray is ejected out of the receiving recess under the restoring force of the first elastic member.

Abstract: A key assembly is assembled to an electronic device. The electronic device includes a housing. The key assembly includes a number of keys and an elastic bracket. The keys are received in the housing. The elastic bracket includes a main plate and a plurality of pairs of pressing fingers extending from the main plate. Each pair of the pressing fingers press one of the keys for mounting the keys between the housing and the elastic bracket.
