Abstract: Examples are disclosed for hosting a communication session between a computer device and a destination communication device in an Internet Protocol (IP) based packet data network. A computer device receives multiple concurrent IP packet data streams each representative of the same content but received over corresponding multiple communication links. The original IP packet data stream comes from the communications server. At least one IP packet data stream representative of the original IP packet data stream traverses a communication link through a second communication device working in tandem with the communications server before arriving at the computer device. The computer device determines a highest quality packet for each corresponding packet in the multiple concurrent IP packet data streams. The computer device then creates a bonded IP packet data stream by selecting the highest quality packet for each time slot from among corresponding time slots of the multiple concurrent IP packet data streams.

Abstract: Disclosed are techniques for mediating a communication session between a communication device operating asynchronously and a communication device operating synchronously. A communications server receives a first set of text data transmitted asynchronously from an asynchronous communication device over a first communication link and converts the text data into a first synchronous stream of audio data. The communications server then establishes a synchronous audio media channel between itself and the synchronous device over a second communication link before transmitting the first synchronous stream of audio data to the second communication device over the established synchronous audio media channel. The communications server may also receive a second synchronous stream of audio data from the synchronous communication device and convert the second synchronous stream of audio data into a second set of text data.

Abstract: Systems and methods for hosting communication sessions are described. A communication session between a first communication device and a second communication device is hosted in an Internet Protocol (IP) based packet data network in which a contact server functions as a bridge service between the first communication device and the second communication device. At least one of a communication link between the first communication device and the contact server and the second communication device and the contact server is initially a cellular communication link over a cellular network. The contact server analyzes at least two call quality characteristics of the cellular communication link and causes the communication device having the cellular communication link to handoff to an alternate communication link on an alternate network when at least one analyzed call quality characteristic of the cellular communication link crosses a threshold level.

Abstract: Systems and methods for intelligently enhancing communication sessions or avoiding dropped and interrupted communication sessions between or among communication devices. Characteristics of a communication link are monitored and are compared to intelligent communication session data to predictively determine whether a handoff may be needed or whether multi-streaming should be invoked or terminated. Intelligent communication session data may be monitored, recorded and/or stored by a handoff service, a bridging service and/or a multi-streaming service, as well as applications executed on communication devices or other network 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. The communication session establishment message includes the VoIP telephone number and a target communication device identifier. The call server establishes a first communication link with the device depending on the quality of a connection with an IP access point. 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: Disclosed is a technique for 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 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 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 or a home cellular 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 or a home cellular network and automatically downloads the queued IP content data from the intelligent cache server. The IP content data is stored in a cache memory in the mobile device.
