Abstract: To facilitate improved delivery of messages via multiple messaging servers, a data abstraction layer is provided. When a first messaging server receives a message destined to a particular party served by a second messaging server, the first messaging server queries the data abstraction layer, and the data abstraction layer then queries potentially multiple databases to obtain information usable to facilitate message delivery, including presence data, preference data, and capabilities data, and provides the information to the first messaging server. The first messaging server may use the presence data to decide whether to send the message, and may use the preference data to decide which device should receive the message. When the first messaging server sends the message to the second messaging server, the first messaging server may provide the second messaging server with the capabilities data to facilitate tailoring of the message content for the destination device.

Abstract: Methods and systems are provided for implementing an alternative timing source for low-cost-Internet-base-station-(LCIB) systems. In accordance with an embodiment, an LCIB has an internal clock. The LCIB is arranged to receive a GPS signal, and to treat timing information embedded in the GPS signal as the LCIB's primary source of timing information for calibrating the internal clock. The LCIB detects a loss of the GPS signal, and responsively uses a macro-network receiver to receive macro-network timing information from a macro network, which is a terrestrial wireless network. The LCIB uses the macro-network timing information to calibrate the internal clock.

Abstract: A method and system is disclosed for dynamically adapting operation of an auxiliary pilot according to reverse noise. An access terminal in a wireless communication system that includes a base station may operate in a first state in which the access terminal transmits a primary pilot signal on an air interface communication link to the base station, and also transmits an auxiliary pilot signal on the air interface communication link to the base station concurrently with transmission of the primary pilot signal. While operating in the first state, responsive at least to receiving a noise-level message from the base station indicating excessive reverse-link noise, the access terminal may transition to a second state in which it ceases to transmit the auxiliary pilot signal but continues to transmit the primary pilot signal.

Abstract: Methods and systems are described for providing a presence service that is particularly useful for mobile telecommunications devices. A plurality of outgoing presence updates are sent to a presence client. The system monitors the level of network traffic and determines whether the client is in a region of high network load. If the client is in a region experiencing a condition of high network load, the system throttles the outgoing presence updates during the condition of high network load. The level of throttling may depend at least in part on the amount of time that has elapsed since the presence client began a presence session, and/or the amount of time that has elapsed since an incoming presence update was received from the presence client. In determining the latter amount of elapsed time, the system may consider only the amount of time elapsed since an incoming non-automatic presence update was received from the presence client.

Abstract: Disclosed herein is a method and system for power management in a subscriber station. The method involves (a) during a communication session between a subscriber station and an access network, determining a packet inter-arrival time for data received from the access network; (b) determining whether the packet inter-arrival time indicates that the communication session is in a high-activity state or, in the alternative, indicates that the communication session is in a low-activity state; (c) if the packet inter-arrival time indicates that the communication session is in the low-activity state, then selecting a first power-saving mode for use by the subscriber station; and (d) if the packet inter-arrival time indicates that the communication session is in the high.

Abstract: A method and system for prioritizing the optimization of sectors within a cellular network using the minimum least squares error (“MLSE”) algorithm is presented. Each sector's throughput and performance metrics are collected over time. Problem sectors are having one or more performance metrics above or below a specified acceptable value are identified. A MLSE algorithm is applied to problem sectors to determine a weight per metric. Next, for each problem sector, the optimized throughput is calculated by substituting the value of a specific problem metric with an acceptable value. Problem sectors are prioritized in order of how much their throughput would improve as a result of an improvement to the problem metric.

Abstract: Disclosed is a method and apparatus for dynamically varying the amount of time a hybrid access terminal operates on a first air interface protocol between instances of temporarily switching over to scan a second air interface protocol for broadcast information such as network operational parameters or page messages. The hybrid access terminal dynamically sets a minimum interval of operation on the first air interface protocol based on how long the access terminal has tended to be temporarily switched away to scan for broadcast information on the second air interface protocol. For example, as the switch-away time increases, the access terminal may increase the interval on the first air interface protocol, and as the switch-away time decreases, the access terminal may decrease the interval on the first air interface protocol.

Abstract: Methods and systems are provided for natural-language surveillance of packet-based communications. Speech data is received, representing at least part of a speech session. The speech data is compared with at least one speech-characteristics profile in an automated manner. The comparing step comprises using natural-language-processing (NLP) to compare the speech data with the profiles on at least one of a lexical level, a syntactic level, a semantic level, a discourse level, and a pragmatic level. It is determined in an automated manner whether the speech data matches any of the profiles. If the speech data matches at least one profile, an indication that the speech data matches the at least one matching profile is responsively stored.

Abstract: Methods are provided for implementing selective personality negotiation during session negotiation. In one embodiment, an access node maintains an access-node-supported set of one or more personalities supported by the access node, wherein the access-node-supported set comprises a personality 0. The access node receives from an access terminal an access-terminal-supported set of one or more personalities supported by the access terminal, wherein the access-terminal-supported set also comprises the personality 0. Responsive to receiving the access-terminal-supported set, the access node negotiates a session-specific set of one or more personalities with the access terminal for use by the access terminal during a session, the session-specific set consisting of personality 0 and a first personality, wherein the first personality is a highest-numbered personality in the intersection of the access-node-supported set and the access-terminal-supported set.

Abstract: Methods and systems for facilitating communication between IMS and non-IMS applications are introduced. A network agent may serve as a proxy between one or more client devices and an Internet Protocol Multimedia Subsystem (IMS) infrastructure. The network agent may transmit a monitoring program to a client device for execution on the client device. The monitoring program may collect data regarding communication applications executing on the client device, and then transmit this data to the network agent. From the collected data, the network agent preferably selects translation logic with which to translate between messages compatible with the communication applications executing on the client device and standardized communication applications executing in the IMS infrastructure.

Abstract: A device detects an alert event and responds by playing out an alert including a static media portion and a first dynamic media portion. The device maintains, in data storage, alert data that includes the static media portion and the first dynamic media portion. A network server sends the device data for updating the alert data stored in data storage. The data for updating the alert data includes a new dynamic media portion. The device stores the received data including the new dynamic media portion and thereafter plays out an alert including the static media portion and the new dynamic media portion when the device detects an alert event.

Abstract: Mobile switching centers (MSCs) in serving systems are interconnected by gateways for tandem free operation. The serving systems route calls involving two mobile stations that use the same compressed digital format through the gateways. The gateways carry the media exchanged during the call in the compressed digital format in order to avoid tandem transcoding. When a serving system hands off a mobile station involved in a tandem free call, the call pathway is extended through the gateways so that the call remains tandem free.

Abstract: A method for the viral distribution of ringback media. A trigger is transmitted from a calling client station to a ringback server during the ringback period of call setup, whereby in response to receipt of the trigger by the ringback server, the subscriber associated with the calling client station is granted the right to the particular ringback media played out during the ringback period. Upon receiving the trigger, the ringback server may request that an indication that the right has been granted be stored in the subscriber's account record. Subsequent to the granting of the right to the particular ringback media to the subscriber, callers to the subscriber may be presented with the particular ringback. Further, these callers may also request to acquire the right to the particular media via the same trigger-initiated process.

Abstract: A method for handling registration requests in a cellular wireless communication system. The method includes determining that a transmission-success rate of messages sent via the forward-link of an air interface is less than a threshold success rate. The method further includes, in response to the determination that the system has less than a threshold transmission success rate, increasing a frequency at which mobile stations register with the cellular wireless communication system via the air interface.

Abstract: Methods and systems are provided for dynamic supplemental-channel (SCH) burst duration. In an exemplary embodiment, a base station provides a wireless coverage area having a plurality of traffic channels, an SCH, an SCH queue, and an SCH burst duration initially set to a first value. The base station computes Ec/Ior for the coverage area, and determines (i) whether the computed Ec/Ior is greater than an RF threshold, (ii) whether the number of mobile stations in the SCH queue is less than a queue threshold, and (iii) whether the number of mobile stations having a traffic channel in the coverage area is less than a traffic-channel threshold. The base station determines a second value based at least in part on each of those determinations, and operates with the SCH burst duration set to the second value.

Abstract: A method and system is disclosed for intelligent power control in a wireless communication system. In accordance with an example embodiment, a first device will operate in a dynamic-power state in which it responds to each power-increment command and power-decrement command received from a second device by incrementing or decrementing transmission power on an air interface. While operating in the dynamic-power state, the first device will recognize when a first threshold number of alternating power-increment and power-decrement commands have been received, and responsively will transition to operating in a steady-power state in which it no longer increments or decrements transmission power in response to power-control commands from the second device. While operating in the steady-power state, the first device will recognize when receives a particular sequence of power-control commands from the first device, and based at least on the recognition will transition to operating in the dynamic power state.

Abstract: Methods and systems are defined that support, in a radio access network, measuring the latency between the radio access network and each respective access gateway of a plurality of access gateways. From these measurements, a list of access gateways, rank ordered from lowest to highest latency, is created. If the radio access network receives an incoming call indication designating that an associated incoming call is latency-sensitive, the radio access network will preferably assign the incoming call to an access gateway that is one with a measured respective round trip latency less than or equal to a median measured respective round trip latency. Additionally, the radio access network maintains a profile for at least some wireless communication devices that use its services.

Abstract: A method and apparatus for processing mobile-IP registration messages. Upon receipt of a mobile-IP registration request (RRQ) message that designates a care-of address matching the mobile-IP home agent's IP address, the RRQ would be dropped. Alternatively, before deciding to drop such an RRQ, the invention may further involve determining whether the home agent is currently functioning as a foreign agent for the requesting mobile node, which would justify the care-of address matching the home agent's IP address. If the home agent is not currently functioning as a foreign agent for the mobile node, then the RRQ would be dropped. On the other hand, if the home agent is currently functioning as a foreign agent for the mobile node, then RRQ processing would proceed as normal.

Abstract: A method and system for selectively applying a cellular-PBX integration service. When a radio access network (RAN) receives a call request for a served wireless communication device (WCD), call setup signaling passes to a call session control function (CSCF), and a determination is made as to whether the WCD is currently checked-into or checked-out of the cellular-PBX integration service. If the WCD is checked-in, the call is set up to an IPPBX server for handling. If the WCD is checked-out, the call is set up back to the RAN for handling. Similarly, the CSCF may receive call setup signaling in response to a call dialed to an IPPBX extension associated with the WCD, and the check-in/check-out status of the WCD may be used as a basis to decide whether to send the call to the RAN for handling or whether to return the call to the IPPBX server for handling.
