摘要： Session Inter-Device (SID) mobility networks (50, 100, 150) are described in which a seamless transfer of a communication session from a first device (56, 106, 116) to a second device (66, 116, 166) can be achieved without interrupting the active session. According to the SID mobility network (50), the transfer can be accomplished by transferring away from the Transferring Node or first device (56) the IP address associated with the active session (58) so that the network (50) will route the session to the desired Target Node or second device (66). The Transferring Node (56) transfers its IP address (58) to the Agent (60) and stops requesting data packets addressed to its IP address (58). The Agent (60) then begins to request and eventually receive the packets addressed to the Transferring Node's IP address (58). The Agent (60) then transfers the packets to the Target Node (66). In an alternate SID mobility network (100), the Transferring Node (106) transfers a session specific IP address (114) to the Agent (110). The Agent (110) then transfers packets sent to the session specific IP address (114) to the Target Node (120). In another SID mobility network (150), the Transferring Node (162) obtains a temporary IP address (170) and transfers its IP address (164) to a Session Agent (166). The Session Agent (166) begins to request and eventually receive the packets addressed to the Transferring Node's IP address (164), and for each received packet determines if it belongs to the session the Transferring Node (162) requested to transfer to the Target Node (176). If it does, the Session Agent (166) will transfer the packet to the Target Node (176) at the Target Node's IP address (178). If it does not, the Session Agent (166) will transfer the packet to the Transferring Node (162) at its temporary IP address (170). In each SID mobility network, the session with respect to the Correspondent Node continues without interruption throughout the transfer, thereby providing a seamless transfer of the session from a first device to a second device.

摘要： A communication system provides for an active handoff of a voice call between a packet switched network and a circuit switched network. An active handoff from the packet switched network to the circuit switched network is accomplished by multicasting the call over forward links of both networks during the handoff. An active handoff from the circuit switched network to the packet switched network is accomplished by multicasting the call over reverse links of both networks during the handoff. The former handoff further may be facilitated by routing the call for each network through a same packet data control switch, and the latter handoff further may be facilitated by routing the call for each network through a same mobile switching center. In order for a subscriber unit to operate concurrently in both networks, the subscriber unit may comprise multiple transceivers or a single transceiver that is rapidly switched between the networks.

摘要： A method and apparatus for multi-modal communication includes a controller (236) operably coupled to at least one multi-modal session proxy server (226). On a per multi-modal session basis, the controller (236) provides the multi-modal session proxy server (226) with a multi-modal proxy identifier (138). The multi-modal proxy identifier (138) is then provided to at least one browser with a per session multi-modal proxy evaluator (220) having a browser proxy identifier (140) wherein the browser proxy identifier (140) is evaluated in view of the multi-modal proxy identifier (138). The multi-modal session proxy server (226) then receives an information request (231) from the browser with per session multi-modal proxy evaluator (220) wherein the requested information is fetched from a content server (240). When the requested information is retrieved, a multi-modal synchronization coordinator (122) notifies the other browser with per session multi-modal proxy evaluator (232), via a multi-modal synchronization interface (234).

摘要： A communication system provides separate subscription keys for a non-subscriber version of a broadcast-multicast flow and a subscriber-only version of the flow, thereby controlling who may store or render the flow. In one embodiment, separate subscription keys may be assigned to a same broadcast-multicast flow. The communication system may then switch the keys used to encrypt the flow, or may use different keys to encrypt different copies of the flow, in order to allow at least non-subscribers to view one version of the flow and only subscribers to view another version of the flow. In another embodiment, the communication system may assign a group subscription key to a group of broadcast-multicast flows that is separate from the keys assigned to each individual flow. The group subscription key may then be used to encrypt a non-subscriber version of any broadcast-multicast flow in the group of broadcast-multicast flows.

摘要： An apparatus and method for selective distributed speech recognition includes a dialog manager (104) that is capable of receiving a grammar type indicator (170). The dialog manager (104) is capable of being coupled to an external speech recognition engine (108), which may be disposed on a communication network (142). The apparatus and method further includes an audio receiver (102) coupled to the dialog manager (104) wherein the audio receiver (104) receives a speech input (110) and provides an encoded audio input (112) to the dialog manager (104). The method and apparatus also includes an embedded speech recognition engine (106) coupled to the dialog manager (104), such that the dialog manager (104) selects to distribute the encoded audio input (112) to either the embedded speech recognition engine (106) or the external speech recognition engine (108) based on the corresponding grammar type indicator (170).

摘要： This coordinated floor and packet scheduling for Push-to-X over Cellular (PoC) services delays a packet data slot assignment until after a PoC floor has been granted (272) by a PoC server (251). By reducing the time period between slot assignment and floor grant, this method reduces the wasting of packet data network resources while the communication device (211) is waiting for a PoC floor grant. Setting up a Push-to-X over Cellular (PoC) call session includes an originating communication device (211) transmitting a PoC floor request message (270) to a PoC server (251), the PoC server (251) sending a PoC floor grant message (272) with treatment type “floor grant” to a packet control function, (232), the packet control function (232) assigning packet data slots to the originating communication device and setting up an active packet data session (280), and communicating a PoC floor grant and packet data slot assignment message (285) to the originating communication device (211).
