  • Publication number: 20140038575
    Abstract: Methods and systems are disclosed for managing conference calls. The method includes establishing a first conference call between a host terminal device and one or more participant terminal devices; receiving a request for adding a non-participant terminal device into the first conference call; selecting a participant terminal device from the one or more participant terminal devices to host a second conference call; establishing the second conference call hosted by the selected participant terminal device, wherein the second conference call includes the non-participant terminal device; and chaining the first conference call and the second conference call through the selected participant terminal device.

  • Patent number: 8611877
    Abstract: Presented are systems and methods for receiving one or more generic commands when coupled to a heterogeneous conference call, the conference call including a plurality of participants coupled to the conference call using one or more mobile devices. The system automatically translates, by a control module the one or more generic commands into one or more native commands recognized by a first conference hosting system, of the plurality of conference hosting systems. The system automatically sends the one or more native commands to the first conference hosting system.

  • Patent number: 8532059
    Abstract: To handle a communication session at a wireless mobile communications device, after receiving an indication of current signal strength of an access point for a wireless local area network (“WLAN”) a signal strength threshold associated with the access point is retrieved. If the communication session is currently carried by a cellular network and the current signal strength exceeds the signal strength threshold, the communication session is switched from the cellular network to the WLAN. A metric is then adjusted based on timing of the switch relative to any switch of the communication session from the WLAN to the cellular network over a preceding time window associated with the access point. Based on the metric, the signal strength threshold associated with the access point is selectively adjusted.
