摘要： An apparatus and method for adaptive broadcast transmission. A broadcast transmission can be received. Insufficiency of a broadcast channel quality can be determined. A negative acknowledgement signal can be sent on a common uplink channel in response to determining the broadcast channel quality is insufficient. The negative acknowledgement signal can be received on the common uplink channel at another location, the negative acknowledgement signal indicating broadcast channel quality is insufficient. The broadcast channel quality can be adjusted in response to receiving the negative acknowledgement signal.

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).
摘要翻译：这种用于Push-to-X over Cellular（PoC）服务的协调层和分组调度延迟分组数据时隙分配，直到由PoC服务器（251）授予（272）PoC成功之后。通过减少时隙分配和分配授权之间的时间间隔，当通信设备（211）正在等待PoC楼层授权时，该方法减少了分组数据网络资源的浪费。在PoC呼叫会话中设置Push-to-X over PoC呼叫会话包括向PoC服务器（251）发送PoC楼层请求消息（270）的始发通信设备（211），PoC服务器（251）发送PoC楼层（232），分组控制功能（232）向发起通信设备分配分组数据时隙并建立活动分组数据会话（280），其中，分组控制功能（232）将分组数据时隙分配给分组控制功能，以及将PoC楼层授权和分组数据时隙分配消息（285）传送到始发通信设备（211）。

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： 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).
