  • Patent number: 7246349
    Abstract: A method for migrating between first and second service enablers in an open service architecture includes registering a second service enabler within open service architecture framework. The properties of the registered second service enabler are compared with the properties of at least one of first service enablers which determines if the second service is backward compatible to the first service enabler. Information concerning whether the second service enabler is backward compatible with the first service enabler is then forwarded to an application using the first service. Additional information that can be sent to the application in the same message includes, e.g., the fact that the second service enabler outdates a first one, a migration strategy and references to interfaces on the second service enabler that the application can already start using.

  • Patent number: 7245672
    Abstract: A method and apparatus for phase-domain semi-coherent demodulator including a receiver for receiving at least a phase component of an input signal. The phase domain semi-coherent demodulator may include a decision unit for forming a decision based on a delayed reference signal and the phase component of the input signal. In addition the phase domain semi-coherent demodulator may include a phase sum adder for subtracting the decision from the phase component of the input signal to form a rotated input phase, a second phase sum adder for subtracting the delayed reference signal from the rotated input phase to form a resulting signal, and a scaler for scaling the resulting signal to form an update signal. A third phase sum adder adds the update signal to the delayed reference signal to form a reference signal.

  • Patent number: 7245649
    Abstract: Methods and apparatus are provided for establishing a connection between a scanner device and a pager device over a sequence of hop channels. The scanner device is repetitively activated and a hop channel is selected from the sequence of hop channels as a function of a present phase. A determination is made as to whether the selected hop channel is a forbidden hop channel. A substitute hop channel is selected from the sequence of hop channels as the selected hop channel if the selected hop channel is a forbidden hop channel. The selected hop channel is monitored for receipt of a paging message during the present phase.

  • Patent number: 7236540
    Abstract: A method of channel estimation in a transmission diversity system includes observing phase differences between channel estimates in a diversity antenna, either determining whether a phase shift is a right half plane or a left half plane and calculating a left/right estimate, or determining whether a phase shift is in a lower half plane or an upper half plane and calculating an up/down estimate, and performing an estimate of the transmitted phase using the sum over at least two slots of one left/right estimate or one up/down estimate.

  • Patent number: 7221935
    Abstract: The advent of new and sophisticated web services provided by Service Providers to users, services that individually require authentication of user and authorization of access, brings the needs for a new service to facilitate such authentication and access, a service referred to as Single Sign-On (SSO). The basic principle behind SSO is that users are authenticated once at a particular level, and then access all their subscribed services accepting that level of authentication. The present invention provides a system, method and apparatus wherein a cellular Federation of mobile network operators becomes an SSO authentication authority for subscribers of this Federation accessing Service Providers having such agreement with a mobile network operator of the Federation.

  • Patent number: 7212679
    Abstract: Method and apparatus for compressing data representing a set of symbols such that each symbol of the set can be separately accessed and decompressed. Each symbol of the set of symbols is encoded in the form of a two-part code wherein a first part of the code is common for all encoded symbols and a second part of the code encodes the data representing a symbol. An identifier is given for each symbol for permitting each encoded symbol to be separately accessed and decompressed. The invention is particularly useful for storing large fonts such as a Chinese or Japanese character set.

  • Patent number: 7203167
    Abstract: A method of controlling the flow of an amount of data from a sending peer to a receiving peer of a predetermined communication protocol is described. The method comprises dividing the amount of data into a plurality of data segments, where the data segments are ordered in a sequence. The segments are sent to the receiving peer in the order of said sequence. The receiving peer acknowledges the correct receipt of a data segment and identifies the last correctly received data segment of the sequence that was received in the proper order of the sequence. The sending peer is arranged such that if it receives a threshold number of duplicate acknowledgements, it performs a retransmission. The threshold number that trigger a retransmission is an adaptive parameter and may assume values larger than three.
