Abstract: A wireless multimedia messaging communications method and apparatus that permits a subscriber to a wireless telecommunications service to receive and generate multimedia messages from known wireless personal communications devices, i.e., cellular/PCS telephones. A multimedia message may be received by the network and selectively delivered to a subscriber of the wireless service. Upon receipt of the message, the network determines an appropriate action to take with respect to the message based upon a profile of the subscriber. The subscriber is then notified by the network of the message and then delivers the message and any multimedia attachments to the message to the subscriber, according to a delivery indication sent by the subscriber to the network. Advantageously, the method allows for the conversion of messages as appropriate, i.e.

The system and method utilizes (a) a behavior transition model based on NE status or “health” indicators for passive monitoring, (b) a status updating mechanism with adjustable or “tunable” parameters based on operating conditions, (c) a derivation procedure for correlating ripple effects, and (d) an early-warning model for proactive management.

Abstract: A method of accessing a text file comprised of individual messages from a cellular telephone comprises the steps of: accessing the text file; selecting one of the individual messages from the text file; formatting the selected message with a network resident user agent; sending the formatted message to the cellular telephone.

Abstract: A method for reconnecting calls affected by a loss of synchronization comprises detecting disconnect of a call and initiating a time-out sequence during which reconnection attempts are performed. The reconnection time-out sequence may be incremented a predetermined number of times before reconnection attempts are terminated and the call is released. Further, a mobile switching center and a serving base station may selectively determine whether reconnection attempts are to be made. Advantageously, resources associated with a call affected by a loss of synchronization are held for a predetermined time. If reconnection is successful, the held resources are bridged to new air traffic channels resulting in enhanced network efficiency.

Abstract: A two-way wireless messaging system has a messaging network, and a two-way messaging device that originates, receives and replies to messages having dynamic message components to and from the messaging network. A transaction server is located within the messaging network for opening and tracking messages among various users of the two-way messaging system, and closing a transaction to prevent further message delivery and replies after a predetermined transaction is completed. A transaction can remain open until a reply has been received by every intended message recipient; until a desired number of message recipient received a message; or until a specified amount of time has expired.

The subscriber receives messages from the messaging network along a first communication channel. The user agent includes a plurality of messages stored therein wherein a predetermined message is stored in the user agent and forwarded to a desired destination in response to an originating message code that is received from a two-way messaging device of the subscriber along a second communication return channel. The originating message code can be expanded by the user agent. The messages stored by the user agent can be modified so that different messages can be forwarded to the predetermined destination. The user agent also maintains location information of the two-way messaging device of the subscriber.

Abstract: A system and method for two-way wireless messaging is disclosed. A plurality of messages are stored within a user agent of the two-way messaging network. The messages correspond to those selected by a subscriber of a two-way messaging service. The messages are encoded and include control information. An originating message transfer code is transmitted from the two-way messaging device of the subscriber to the two-way messaging network. The originating message transfer code includes, among other things a message number and a modifier that specifies customizations that are to be applied to a message. The originating message code is then expanded within the user agent, and the expanded message is forwarded to desired destinations based on the content of the originating message transfer code.

Abstract: A telecommunications system is arranged to efficiently route digital information from a mobile network to a Public Switched Telephone Network (PSTN) and vice versa by interposing a packet network between the mobile network and PSTN so that digital information originating from the wireless network at a first data rate may be forwarded over the packet network at that rate and then sent over a direct connection from the packet network to the PSTN at a second data rate expected by the PSTN. In this way the conversion of the digital information from the first to the second data rate is performed only when needed, i.e., at the ATM switch connected to the PSTN.

Abstract: A multipoint-to-point wireless System using directional antennas in an indoor environment. Optical pulses in an asynchronous transfer mode network may be converted into radio pulses, which are transmitted by a radio transmitter to a radio receiver, and then may be reconverted into optical pulses. Transmitter antennas having predetermined beamwidths are used and positioned within the indoor environment for transmitting data signals at a selected carrier frequency. A receiver antenna with a predetermined bandwidth is positioned within the indoor environment for receiving data signals transmitted at the selected carrier frequency. Amplitude Shift Keying (ASK) is used so that the output between transmitted data packets is zero, thereby allowing other users to utilize the system during the gap between the packets.

Abstract: The invention relates to the use of CDMA techniques. Data signals to be transmitted from a plurality of wireless devices are spread across a common bandwidth. The data signals are received by a base station as a composite spread signal. The base station partially despreads the composite spread signal with unique codes to extract data signals from individual wireless devices. The data rate and quality of service requirements for each wireless device are used to calculate a power factor and a control signal is sent to control the power from a particular wireless device. In addition, a probability of transmission value is calculated based on an equivalent current load value and an equivalent population value. The probability of transmission value determines whether a particular wireless device is allowed access to an uplink frequency channel.
