    Abstract: Information may be provided to a telephony customer from an overlay service by causing a second stream of audio information to be overlayed on a primary stream of audio information. The overlayed information may be whispered to the user by causing the overlayed information to be compressed into a limited frequency spectrum which is inserted into a manufactured gap in the primary audio stream. This allows the user to continue to hear the main audio stream while also hearing the overlayed information. The overlay service may provide administrative information, advertisements, music, and/or Internet search results via the overlayed audio. Users may issue commands to the overlay service, to have particular information transmitted via overlayed audio. Where the user is also associated with a telephony application running on a computer platform, the overlayed information may be incorporated onto the information being shown to the user on a computer display.

  • Publication number: 20130142088
    Abstract: In a particular embodiment, a circuit switched (CS) paging message is received at a multi-mode communication device. The CS paging message is received when a packet switched (PS) service is active at the multi-mode communication device. A PS precedence feature is activated at the multi-mode communication device that prioritizes PS communications over CS communications. A CS bearer connection is established with a CS network in response to receiving the CS paging message, and an incoming call notification message that identifies a calling party is received from the CS network. Upon receipt of the incoming call notification message, the CS bearer connection with the CS network is released. A notification of a missed incoming call from the calling party is displayed (e.g., substantially in real-time) via a user interface.

    Abstract: Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.

  • Publication number: 20130142128
    Abstract: A wireless communication system is provided that includes a base station receiving a plurality of input signals that are selectively provided to a plurality of precoders. The precoders perform precoding operations on the input signals and output a first signal. The base station includes an algorithm that minimizes total transmit power per antenna under signal to interference and noise ratio (SINR) target constraints or maximizes the SINR under a sum of power constraint so as to determine power allocation and obtain efficient precoders. A number of mobile receiver units receive the first signal and performs their respective operations to extrapolate the linear estimate of the input signals.

    Abstract: The present invention relates to optimized radio resource utilization in a cellular telecommunication system. A base station of such a system evaluate a capacity metric of the base station and capacity metrics of neighboring base stations. In response to detecting that the capacity metric of the base station is below a threshold with respect to the capacity metrics of the neighboring base stations, the base station enters a stand-by mode and releases its radio resources that essentially define a cell associated with the base station so that the released radio resources become available for allocation to at least one of the neighboring base stations.

    Abstract: A method for reporting channel state information is provided in the invention, which includes: an eNB (eNodeB) indicating UE to feed back CSI (channel state information) reporting of one or multiple component carriers at a time; the UE feeds back the CSI reporting of one or multiple component carriers at a time according to the indication of eNB. The invention also provides an eNB, which is configured to: indicate UE to feed back CSI reporting of one or multiple component carriers at a time. In the invention, the problem how the UE performs channel state information reporting for multiple (downlink) component carriers in the LTE-A system is solved, which can not only ensure the reliability of transmitting channel state information but also reduce the feedback delay of channel state information as soon as possible.

    Abstract: A resource control method and device are provided in the present invention. The method includes: a base station collecting in real time an S1 transmission bandwidth occupied by one or more operators in the base station; and, when a user equipment (UE) initiates a service request, according to the remaining S1 transmission bandwidth of the operator to which the UE belongs, the base station determining whether the UE is allowed to access to the service or not. By collecting in real time the S1 transmission bandwidth resource occupied by each operator in the system, the present invention realizes resource control, ensures each operator's profit, avoids the case that the quality of service of the users of other operators is damaged or can not be accepted since one operator occupies excessive S1 transmission resource, thus guaranteeing user experience and enhancing user satisfaction.
