Abstract: Disclosed are techniques for hosting a communication session in a call server between communication devices. The call server functions as a bridge service between the communication devices joining an original communication link between the first communication device and the call server with a second communication link between the second communication device and the call server. The first communication device includes at least two RF transceivers each capable of communicating with the call server over a separate network using separate telephone numbers. The call server establishes an alternate communication link with the first communication device on an alternate network and joins it with the second communication link before disabling the original communication link to maintain the communication session between the communication devices.

Abstract: Disclosed are techniques for establishing a communication session in a call server between communication devices. A call server receives a communication session establishment message from a communication device that has an associated VoIP telephone number. The message is indicative of the communication device wanting to place a call to a target communication device that has an associated target telephone number. The communication session establishment message includes the VoIP telephone number, the target telephone number and a connection status indicator. The call server establishes a first communication link with the device based on the connection status indicator. The call server then establishes a second communication link with the target communication device. The call server may then join the first and second communication links to establish a communication session between the communication devices.

Abstract: Examples are disclosed for user feedback to enable a handoff profile for a dual-mode hybrid mobile device.

Abstract: Embodiments of the invention provide systems and methods for handling emergency calls. According to one embodiment, handling an emergency call can comprise receiving an emergency call from a calling number, determining whether the calling number has been ported from an original geographic location to a new geographic location, determining a spatial location for the calling number based at least in part on whether the calling number has been ported, identifying a public safety system for handling the emergency call based on the determined spatial location for the calling number, and routing the emergency call to the identified public safety system. Identifying the public safety system for handling the emergency call can comprise using a point-in-polygon check of the determined spatial location for the calling number against known spatial boundaries for a plurality of public safety systems.

Abstract: An apparatus and a method for IP-based call answering point selection and routing. When an IP-based call is placed to an answering point such as, for example, a Public Safety Answering Point a location for the caller can not be determined using traditional DNIS and ANI based techniques. In the present invention, a geographic location (geolocation) for the caller is determined, from as IP address associated with the caller, using a database. The database comprises information obtained from a plurality of IP location sources (e.g. Skyhook Wireless Inc.'s Loki™, Federal Communications Commission (FCC) mandated WiFi™ hotspot registration data). An answering point is selected from a plurality of answering points as a function of the caller's location. The call is routed to the selected answering point and the caller's location information is provided to that answering point.

Abstract: Disclosed is a method of predictively caching IP content data for a mobile device. In the mobile device, a content request is sent to an intelligent cache server over an IP network, the content request indicative of recurring IP content data of interest to the mobile device. The intelligent cache server retrieves the requested IP content data from content servers and queues the requested IP content data in a buffer associated with the mobile device. A notification message is sent to the mobile device indicating that the requested IP content is queued. The mobile device determines whether it is connected to a non-cellular IP network access point and automatically downloads the queued IP content data from the intelligent cache server when connected to a non-cellular IP network. The IP content data is stored in a cache memory in the mobile device. Other embodiments are disclosed.

Abstract: Disclosed are techniques for creating a conference connection. An IP network hosted application server receives an invite message that includes contact information for conference participants. The application server creates a customized invitation message using the contact information and sends it to a device associated with conference participants. The application server receives response messages accepting the invitation from participants' devices that include a means of contact for conference participants. The application server creates a conference data record including the means of contact associated with the conference participants and a date/time for the conference. The application server forwards the conference data record to a conference server operable to initiate a conference to the conference participants at the date/time specified using the means of contact included in the response messages. The connections are joined into a conference with other conference participants.

Abstract: Disclosed are techniques for suppressing a handoff of a media stream associated with a communication session between communication devices one of which is a mobile device capable of making and receiving calls on separate networks. The technique suppresses an automatic media stream handoff between the mobile device and an IP network based call server in which the automatic media stream handoff comprises switching a communication path of the media stream between the mobile device and the IP network based call server from one including an IP access point to one including a cellular access point. The technique stores a list of IP access points to which the mobile device has previously connected and accepts input indicative of selecting one or more of the IP access points. Thereafter, either the mobile device or the call server prevents an automatic handoff process for any of the selected IP access points.

Abstract: Techniques for hosting a communication session between a first communication device and a second communication device in an IP network are described. A contact server establishes separate communication links between itself and the communication devices wherein the communication links may traverse one or more telephony networks. The contact server receives personalized user session data generated by a user of a communication device. The personalized user session data may be indicative of a subjective evaluation of the quality of the communication link or a preference for a particular telephony network. The contact server may then cause the communication device to establish a new communication link with the contact server and handoff from its current communication link to the new communication link when the subjective evaluation of the quality of the communication link crosses a threshold level or a condition for a preference for a particular telephony network is detected.

Abstract: A communication session between a first communication device and a second communication device is hosted in an Internet Protocol (IP) based packet data network. A contact server functions as a bridge service between the first communication device and the second communication device. A communication link between the first communication device and the contact server or the second communication device and the contact server is initially a voice-over IP (VoIP) communication link over a wireless data network comprised of a first packet data media stream. The contact server receives the first packet data media stream and at least one other packet data media stream from the first communication device and combines them into a single packet data media stream before transmitting the combined single packet data media stream to the second communication device.

Abstract: A communication session between a first communication device and a second communication device is hosted in an Internet Protocol (IP) based packet data network. A contact server functions as a bridge service between the first communication device and the second communication device. A communication link between the first communication device and the contact server or the second communication device and the contact server is initially a voice-over IP (VoIP) communication link over a wireless data network. The contact server analyzes a call quality characteristic of the VoIP communication link and causes the communication device having the VoIP communication link to handoff the VoIP communication link from the wireless data network to a cellular communication link on a cellular network when the analyzed call quality characteristic of the VoIP communication link crosses a threshold level. Other embodiments describe handing off from a cellular communication link to VoIP communication link.
