  • Publication number: 20090133035
    Abstract: An inventive system and method for developing and deploying converged services having incoming messages from a network and/or a service includes a graphical front end for creating flows having one or more event match criteria, each event match criteria having corresponding logic, a generator for generating runtime code from the flows, and a runtime engine operable to perform the runtime code, in which an incoming message is matched to one of the event match criteria and the corresponding logic is executed. The logic can be logic performed by the converged service. A user of the inventive system can switch between the flow created in the graphical interface and the runtime code generated from the flow.

  • Publication number: 20080032734
    Abstract: In a wireless communication system, an apparatus and a method are provided for controlling reverse link interference among access terminals that are power controlled by a sector of a base station. In an embodiment, the maximum effective noise power spectral density is used as a parameter for controlling the level of reverse link loading, by setting a reverse activity bit (RAB) to signal the access terminals to reduce their data rates in order to minimize interference between the access terminals if the maximum effective noise power spectral density is above a predetermined threshold.

  • Publication number: 20070091815
    Abstract: Embodiments described herein relate to providing adaptive encoding of real-time information in packet-switched wireless communication systems. In an embodiment, a rate-adaptation unit may be configured to receive local as well as end-to-end feedback information associated with data transmission (such as data delay, packet loss, transmit power headroom, channel condition, sector loading, the amount of buffered data, etc.) from a wireless access module in communication with wireless/wired networks, and adapt the real-time information encoding in accordance with such feedback information.

  • Publication number: 20070091816
    Abstract: The disclosure relates to reverse link lower layer assisted video error control. A method may encode video data, form a packet with the encoded video data, and transmit the packet across a wireless channel to an access network. A medium access control (MAC) layer may receive a negative acknowledgement (NAK) from the access network. The method may determine whether the received NAK is associated with a packet that contains video data. If the received NAK is associated with a packet that contains video data, the method may perform error control.

  • Publication number: 20070070908
    Abstract: Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

  • Publication number: 20050060317
    Abstract: This system for generating message transformation and validation software uses interface definition documents as inputs. An interface definition consists of an internally consistent set of message definitions, data dictionary entries, transformation rules, and validation rules. A user-friendly graphical user interface provides the requirements engineer or other user with the ability to specify these documents. This graphical user interface is a structured table and rules editor that allows the requirements engineer to enter and validate interface definitions to ensure that the definitions meet certain predetermined requirements. The generation system takes the interface definition documents as input and generates various software artifacts to transform and validate messages. W3C XML schemas are generated from an interface definition for assistance with code development, for use as standards-compliant interface definition that can be reused and composed with other schemas, and for validating messages.

  • Publication number: 20050013282
    Abstract: An access terminal (206) configured for wireless communication with an access network (204) within a sector (1032). The access terminal (206) includes a transmitter (2608) for transmitting a reverse traffic channel to the access network (204), an antenna (2614) for receiving signals from the access network (204), a processor (2602) and memory (2604) in electronic communication with the processor (2602). Instructions stored in the memory (2604) implement a method of determining whether a current power allocation grant (1374) for a flow (1216) on the access terminal (206) has been received from the access network (204). If the current power allocation grant (1374) is still active, a current power allocation (1338a) for the flow is set equal to the current power allocation grant (1374). If the current power allocation grant (1374) has not been received, the current power allocation (1338a) for the flow is determined.

Instructions stored in the memory (2604) implement, for each flow (1216) of a plurality of flows on the access terminal (206), determining the flow's total available power (1238). The access terminal's total available power (1234) is determined by summing each flow's total available power (1238). A packet is transmitted to the access network (204) at a power level that does not exceed the access terminal's total available power (1234).
