Abstract: The present disclosure is relates to a conductive film and a manufacturing method thereof. The conductive film includes a base layer, a TPU complex layer, a conductive layer and a TPU surface layer. The TPU complex layer includes a TPU heat-resistant layer and a TPU melting layer. The TPU heat-resistant layer is disposed on the TPU melting layer, and the TPU melting layer is disposed on the base layer. The conductive layer includes a conductive circuit disposed on the TPU heat-resistant layer. The TPU surface layer is disposed on the conductive layer. Utilizing the TPU complex layer, the conductive layer does not contact directly with the base layer to avoid breaking the conductive line of the conductive layer when the base layer is pulled. Therefore, the lifetime of the conductive film can be increased.

Abstract: An electronic device includes a metal back cover, a metal frame, a first antenna module and a second antenna module. The metal frame includes a first and a second disconnection portion, a first and a second connection portion. The first and the second connection portion are connected to the metal back cover. The first disconnection portion is separated from the first connection portion, the metal back cover and the second disconnection portion to form a first slot. The second disconnection portion is connected to the second connection portion and is separated from the metal back cover to form a second slot. The first antenna module is connected to the first disconnection portion, and forms a first antenna path. The second antenna module is connected to the second disconnection portion, and forms a second and a third antenna path with the second disconnection portion and the metal back cover.

Abstract: Aspects of the disclosure provide a method for call management. The method includes receiving a signal from one of a first transceiver and a second transceiver in an electronic device. The signal indicates an incoming call managed by a first service provider that the electronic device subscribes service from. The method further includes determining whether the other of the first transceiver and the second transceiver is operative in an active call managed by a second service provider that the electronic device subscribes service from, and rejecting the incoming call when the other transceiver is operative in the active call managed by the second service provider.

Abstract: A method for efficient wireless communications includes transmitting a connection request via a communications apparatus to a peer device to try to establish a connection with the peer device to trigger a Circuit Switch Fallback (CSFB) procedure; starting a predetermined timer via the communications apparatus when transmitting the connection request; and when there is no response message received from the peer device by the time the predetermined timer expires, transmitting the connection request again via the communications apparatus to the peer device at least once to retry to establish the connection with the peer device.

Abstract: A method for efficient wireless communications includes transmitting a tracking area update (TAU) request message by a communications apparatus to a peer device to initiate a TAU procedure; receiving a paging message by the communications apparatus from the peer device after transmitting the TAU request message; and in response to receipt of the paging message, retransmitting the TAU request message by the communications apparatus to the peer device to reinitiate the TAU procedure immediately or transmitting a request message by the communications apparatus to the peer device immediately, without waiting a predetermined time period.

Abstract: The method and apparatus for CSFB are provided. The method for processing a Circuit Switched Fallback (CSFB) procedure in a user equipment (UE) includes the steps of receiving the switching command when the CSFB procedure is triggered to establish a CS call, and searching for a 2G/3G cell, when the UE fails to fall back to a target cell indicated by the switching command. In addition, the method for CSFB further includes the step of initiating a timer when the UE fails to fall back to the target cell indicated by the switching command, and searching for the 2G/3G cell until the timer is expired.
