Abstract: Mobile devices, base stations, and/or relay stations may implement CSFB (circuit switched fallback) operations by using RRC (radio resource control) connection release and/or handover procedures. If the CSFB RAT (radio access technology) target is not well configured, the UE may be informed and provisioned by the NW during a CSFB procedure with the information to return to LTE. Having this information, the UE may perform an autonomous search of LTE cells after the CSFB call release, speeding up return to LTE. To minimize potential call failures during CSFB, the UE may autonomously perform an additional cell search, in particular a search for cells on a RAT different from the initial target RAT. This creates an opportunity to prevent call failure of CSFB calls that would otherwise fail. The UE may be provisioned during the CSFB procedure with information to perform the additional cell search, should such a search be necessary.

Abstract: A system for monitoring traffic characteristics between gateways in a computer network. The system includes a processor to construct a packet frame consisting of a sequence of network packets for transmission by a transmit gateway to receive gateways.

The processor then transmits the reordered network packets in the packet frame from the transmit gateway to the plurality of receive gateways.

Abstract: A first terminal receives a first Timing Advance (TA) value from a base station and includes a second TA value that is obtained based on the first TA value in a Scheduling Assignment (SA) signal. The first terminal transmits the SA signal to a second terminal at downlink (DL) timing for receiving a downlink signal of the base station in cellular communication. When a length of a Cyclic Prefix (CP) that is set for the D2D communication and a length of a CP that is set for the cellular communication are different, the first terminal transmits data of the D2D communication to the second terminal at first timing that is obtained by applying the second TA value to the DL timing.

Abstract: A system includes a transmitter to drive a transmission signal via a first and second transmission line. One half of the transmission signal is applied to the first transmission line and the other half of the transmission signal is applied to the second transmission line. An antenna radiates the transmission signal from the transmitter and receives a reception signal. The reception signal is driven in the opposite direction of the transmission signal on the first and second transmission lines. A plurality of differential amplifiers receive the reception signal from different sections of the first and second transmission lines and generate amplified output signals to a receiver output path having a first and second receiver transmission line. The differential amplifiers reject the one half of the transmission signal applied to the first transmission line and the other half of the transmission signal applied to the second transmission line.

Abstract: According to an example, in an AC pool including a MAC and a plurality of LACs registered on the MAC, after a first LAC is registered on the MAC, the MAC issues a first traffic rule to the first LAC, wherein the first traffic rule redirects a discovery packet sent from an AP to the MAC. When receiving the discovery packet sent from the AP or receiving a discovery packet sent from the AP and forwarded via a LAC, the MAC selects, from a plurality of the LACs, a second LAC for handling the AP. The MAC generates a second traffic rule associated with the AP and the second LAC, and issue the second traffic rule to a plurality of the LACs, so that when another LAC receives a communication tunnel protocol packet sent from the AP, the other LAC redirects the communication tunnel protocol packet to the second LAC.
