  • Patent number: 9019843
    Abstract: In a mobile data network with a breakout system, when data is broken out, the RLC function is split into two different flows, between the UE and the breakout system and between the breakout system and the RNC. These two flows are processed by different RLC functions that may drift apart and become out of synchronization resulting in errors that diminish the user's quality of experience. Other errors may also occur in communication on these two different flows. The breakout system attempts to correct these errors using data stored locally in communication data structures for the two data flows. If the errors cannot be corrected, the breakout system can initiate an RLC reset into both of these flows to resynchronize the data communication.

  • Publication number: 20140328220
    Abstract: Front end circuitry for a wireless communication system includes a first antenna node, a second antenna node, a first triplexer, a second triplexer, and front end switching circuitry coupled between the first triplexer, the second triplexer, the first antenna node, and the second antenna node. The front end switching circuitry is configured to selectively couple the first triplexer to one of the first antenna node and the second antenna node and couple the second triplexer to a different one of the first antenna node and the second antenna node. By using a first triplexer and a second triplexer in the mobile front end circuitry, the mobile front end circuitry may operate in one or more carrier aggregation configurations while reducing the maximum load presented to the first antenna node and the second antenna node, thereby improving the performance of the front end circuitry.

    Abstract: A high-frequency switch module includes a first diplexer arranged to receive a GPS signal and to send/receive a GSM 1800 communication signal and a GSM 1900 communication signal, and a switch element arranged to switch between the sending/receiving of the GSM 1800 and the sending/receiving of the GSM 1900 communication signal. A SAW filter having a passage band corresponding to the frequency band of the GSM 1900 communication signal and a SAW filter having a passage band corresponding to the frequency band of the GSM 1800 communication signal are connected to the switch element. A line length of a transmission line for connection to the SAW filter which provides a reflection phase closer to the open side for the GPS signal as viewed from the switch element is greater than that of a transmission line for connection to the other SAW filter.

  • Patent number: 8848646
    Abstract: A data rate in MIMO transmission is increased to a maximum even when the number of transmitting antennas of a mobile station apparatus is different from the number of transmitting antennas of the mobile station apparatus supported by a base station apparatus. The base station apparatus (eNodeB) reports the maximum number of supported antennas of the mobile station apparatus (UE) supported by the base station apparatus (eNodeB) to the mobile station apparatus (UE) (ST11). The mobile station apparatus (UE) compares the number of supported antennas with the number of transmitting antennas of the mobile station apparatus (UE), selects the smaller number of antennas as a number of virtual antennas (ST12), and reports the number of virtual antennas to the base station apparatus (eNodeB) (ST13). The base station apparatus (eNodeB) instructs the mobile station apparatus to transmit a data channel signal in accordance with the number of virtual antennas (ST15).

  • Patent number: 8824420
    Abstract: A method and system generating signal to select a subset of antennas from a set of antennas to transmit user data in a wireless communication system. User data are transmitted during a first transmission time intervals (TTI) using a first subset of antennas. Pilot tones are transmitted during a second TTI using a second subset of antennas. Corresponding channels are estimated for the first subset of antennas and the second subset of antennas from the user data and the pilot tones. Then, based on the estimating, an optimal subset of antenna is selected from the first subset of antennas and the second subset of antennas to transmit the user data during a sequent TTI, and in which the selecting is performed adaptively.

  • Patent number: 8797981
    Abstract: Mobile network services are performed at the edge of a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. A subscriber database is dynamically built to support authorization, authentication and accounting for the services performed at the edge of the mobile data network for the broken out data. The core network thus has a subscriber database that is used for non-broken out data, while a separate subscriber database that is not in the core network is used for broken out data.
