The invention comprises a videoconference server () comprising: &#x2014;an audio processing module () configured to, &#x2218;calculating an average audio processing delay of processing audio packets intended to the second client device, in order that the second client device may synchronize a received video packet with the associated received audio packet, &#x2014;a video router () configured to: &#x2218;duplicate the video packet and temporarily store the duplicated video packet, &#x2218;receive a retrieving request from the second client device () for retrieving a lost video packet, &#x2218;retrieving the duplicated video packet associated with the identification information in the video buffer ().

Videoconference server, client device, videoconference system and method

A communication device comprising: a tag reader () configured to: &#x2014;read an identification tag signal () comprising an identification indication of a target communication device (), a discovery module () configured to: &#x2014;send a discovery request () to a registration service infrastructure (), comprising the identification indication, &#x2014;receive a discovery response () from the registration service infrastructure (), comprising network location information of the target communication device (), a session control module () configured to: &#x2014;send a shift request () to a home communication node () for shifting a communication session from the initial communication device to the target communication device (), wherein the home communication node () handles all communication sessions with the initial communication device, the shift request () comprising the network location information of the target communication device (), &#x2014;terminate the communication session with the remote communication device ().

Method and system for shifting a communication session

A communication terminal comprising: a radio interface and a WLAN communication module configured to: generate and send an association request; receive an association response; and establish IP connectivity. The communication terminal also comprises a service selection module configured to select a computer-implemented service to be accessed; and a service execution control module configured to execute software application code implementing the selected computer-implemented service. The WLAN communication module is further configured to: in response to receiving a service selection command from the service selection module, generate an association request comprising a service identifier which identifies the selected service; parse the association response received through the radio interface to detect a link carried in the association response, wherein the link points to a network address of an application server suitable for delivering application data corresponding to the selected computer-implemented service; and initiate data communication with the network address for downloading application data.

Service delivery through wireless access systems

Methods of and systems for establishing an augmented communication channel between an interactive voice response (IVR) system and an electronic device associated with a user are disclosed. A first method comprises sending, an audio call request; establishing an audio channel; establishing a data channel between the IVR system and the electronic device; receiving, via the data channel, IVR tree data, the IVR tree data allowing association of a position of the user with respect to the menu navigation structure; sending, via one of the audio channel and the data channel, a user selection relating to the IVR tree data; and receiving, via the other one of the audio channel and the data channel, an updated position of the user with respect to the menu navigation structure based on the user selection. A method to be executed by the IVR system is also disclosed.

System for and method of establishing an augmented communication channel with an interactive voice response system

A method for anticipating the loss of connectivity between a mobile device and a wireless short-range access point among a plurality of such wireless access points, this method comprising the following steps: &#x2014;collecting a plurality of paths corresponding to the mobile device movements within the coverage areas of the access points to which the mobile device was successively associated without loss of connectivity, each path comprising a root access point at which a connectivity is originated and a dead-end access point at which the connectivity is lost; &#x2014;detecting the current access point to which the mobile device is currently associated; &#x2014;identifying the paths comprising the current access point; &#x2014;computing the risks of losing the connectivity when following each of the identified paths from the current access point to the root access point or to the dead-end access point of each of the identified paths.

Method for WiFi connectivity loss anticipation

A multimode mobile telephone terminal (T) allowing the transfer of a telephone call from one wireless network to another, comprising: an interface (CSI) for supporting circuit-switched calls, an interface (PSI) for supporting packet-switched calls, a call transfer manager (HOM) for deciding on call transfers, an access monitor (ACM) for activating or deactivating the devices (D-D, . . . etc.) that said interfaces (CSI and PSI) comprise, based on: information on the state of those devices' availability, the type and state of the radio connectivity offered by the terminal, and preferences defined by a user or mobile fleet administrator; a call manager (CH) for: managing the calls presented to the user based on the current status of each of the devices (D-D. . . etc.) that the interface (CSI) comprises to support circuit-switched calls, and that the interface (PSI) comprises to support packet-switched calls, and managing the switchover of a multimedia session, should the need arise, from one device (D-D. . . etc.) to another based on signals from the call transfer manager (HOM); This call manager (CH) comprises an abstraction layer (AL) that makes it possible to exchange generic commands and generic information with any communication device D-D. . . etc that the interface (CSI) may comprise to support circuit-switched calls, and that the interface (PSI) may comprise to support packet-switched calls.
