Abstract: A transmit switched antenna system utilizes one of several antennas selection protocols combined with feedback from a receiving device to take advantage of time and space transmission for the same information. A transmit device transmits first information over a first subset of a set of antennas and receives an ACK or NACK from the receiver along with a channel quality indicator. If a NACK is received, the transmitter selects a next antenna subset for transmission, based on the antenna selection protocol utilized. One protocol randomly selects the next subset and does not require the channel quality indicator. Another protocol determines the next antenna subset based on channel quality history, and a third protocol selects the next antenna subset based on expectation of retransmissions for different protocols.

Abstract: A particular method includes receiving, via an interactive voice response (IVR) unit, an audio content item during a first call. An indication of an insertion point at which to insert audio advertising in the audio content item is also received during the first call. The method further includes receiving via the IVR unit an audio advertisement during a second call. The audio advertisement is automatically inserted into the audio content item at the insertion point to create a package.

Abstract: A system includes an event notification system coupled to a communication network element and to a subscription database. In response to a subscribe message for a party received from the communication network element, the event notification system determines at least one service from a plurality of services for the party from the subscription database, sends a service subscribe message to a device associated with a service for each service of the at least one service, determines a notification value for the party based on service pushed values received in response to each sent service subscribe message, and sends the notification value to the communication network element. The notification value is used by the communication network element to determine whether to invoke an internet protocol multimedia subsystem service for an incoming call to a communication address associated with the party.
