Abstract: A mobile station (MS) (100) is capable of communicating user information through both a wireless connection (224) and a wired connection (222). The MS establishes (502), between the MS and a communication device coupled to the communication system, a first one of the wireless connection and the wired connection, the wired connection existing through a wired local area network (LAN). The MS communicates (504) a first portion of the user information between the MS and the communication device through the first one of the wireless connection and the wired connection. Subsequently, the MS establishes (506), between the MS and the communication device a second one of the wireless connection and the wired connection, the second one different from the first one. The MS then communicates (508) a second portion of the user information through the second one of the wireless connection and the wired connection.

Abstract: A wireless client (100) maintains (302) a shopping list of items desired by a shopper, and then transmits (304) the shopping list to an in-store shopping system (200). The in-store shopping system receives (306) the shopping list and then generates information identifying where to find the items and further identifying where the wireless client is positioned in the store. The in-store shopping system communicates (308) the information to the wireless client, which then displays (310) the information to the shopper.

Abstract: In a portable subscriber unit (200) a processor (204) is arranged and programmed to maintain (302) in a memory (208) a list identifying a plurality of devices which are to be connected quickly through a communication network, and to establish (304) a new connection with the communication network. The processor is further arranged and programmed to perform, in response to establishing the new connection, when necessary for pre-programming the communication network to minimize the connection setup time for subsequent connections with the plurality of devices, at least one of the steps of (a) sending names of the plurality of devices to a domain name server (DNS) of the communication network to obtain IP addresses corresponding to the names, thereby causing the DNS to cache the IP addresses of the plurality of devices for faster servicing of subsequent connections, and (b) transmitting a dummy Internet Protocol (IP) packet to said plurality of devices.

Abstract: A synchronization signal includes a plurality of predetermined synchronization symbols shaped by a predetermined symbol pulse. A receiver (100) receives (202) a signal including the synchronization signal, and a processor (106)determines (204) a first plurality of cross-correlations between the predetermined symbol pulse and the received signal. The processor calculates (206) a plurality of sums of products of the plurality of predetermined synchronization symbols and a predetermined subset of the first plurality of cross-correlations. The plurality of sums are mathematically equivalent to a second plurality of cross-correlations between the synchronization signal and the received signal. The processor locates (208) a peak of the plurality of sums to establish receiver synchronization.

Abstract: A selective call messaging system delivers (602, 604, 606) a master message (324) addressed to a first group of subscriber units (102) and a corresponding records message (326) addressed to a second group of subscriber units. The records message comprises a record (514). A subscriber unit of the second group presents (736) a subscriber-customized group message (332) to a user. The subscriber-customized group message is formed (722, 726, 730, 734) from the master message and from at least one of the record, and local information (328) stored in the subscriber unit.

Abstract: A caller makes (302) a telephone call to a second telecommunication system (108) from a telephone port (202) in a first telecommunication system (104). The first telecommunication system then ascertains (304) whether the second telecommunication system is a type for which receiving music on hold is appropriate. The first telecommunication system disables (308) music on hold for the telephone call, in response to ascertaining that the second telecommunication system is not the type for which receiving music on hold is appropriate.

Abstract: An agent (100) is associated with each of a plurality of devices (201-204) for arbitrating between a talk stream generated by the device and a listen stream intended for the device and generated by another device on a network (210). In the agent a “Talk Mode” (300) is defined in which the agent passes the talk stream from the device to other devices participating in the conference while blocking all listen streams intended for the device, and a “Listen Mode” (400) is defined in which the agent blocks the talk stream of the device from the network and passes a single listen stream from the network to the device. The agent makes a decision to enter one of the Talk Mode and the Listen Mode, wherein the decision is based upon a presence of at least one of the talk stream and the listen stream, and wherein the decision is further based upon a comparison of source identifiers of the talk and listen streams when required to resolve a conflict.

Abstract: A demodulator (604) demodulates (802) a block of symbols of a signal through a single-symbol matched-filter technique, thereby generating a first set of data; and demodulates (804) the block of symbols through a multi-symbol matched-filter technique, thereby generating a second set of data. The demodulator obtains (806-810) a measurement of a characteristic of the signal, and chooses (814-816) one of the first and second sets of data for output, based upon the measurement.

Abstract: A receiver (200) receives (402) a first signal including a sync portion (308) having a carrier acquisition segment (302) and a timing synchronization pattern (304), and a processing system (216) of the receiver calculates (404) a first plurality of squared magnitude Fourier transforms at a first plurality of frequencies on the carrier acquisition segment. The processing system derives (406) an initial carrier frequency error estimate by locating a peak in the first plurality of squared magnitude Fourier transforms, and corrects (408) the sync portion according to the initial carrier frequency error estimate, thereby producing a carrier-corrected sync portion. The processing system then removes (410) the timing synchronization pattern from the carrier-corrected sync portion, thereby producing a second signal having a residual carrier error.

Abstract: A method and apparatus provides for motion activated control of an electronic device. The method activates a function, such as a backlight feature, of an electronic device, by storing at least one motion sequence and a function corresponding to each motion sequence. Motion of the electronic device is monitored, and when it is determined that the monitored motion corresponds to a motion sequence, the stored function that corresponds to the stored motion sequence is activated. The apparatus has a motion transducer that senses motion of the electronic device, and a device controller in communication with the motion transducer that activates the corresponding function when a motion processor determines that the stored motion sequence has been sensed by the motion transducer.

Abstract: A portable communication unit (PCU) (102) performs (402) a registration process with a wireless local area network (WLAN) (104) when the PCU moves within communication range of the WLAN. The PCU and the LAN cooperate to create (404) a local information profile describing at least one of types of information and methods of delivering the information desired by a user of the PCU. During the registration process, the PCU and the WLAN cooperate further to determine (406) whether a type of information described in the local information profile is out-of-date or missing in the PCU. If so, the WLAN downloads (408) the type of information to the PCU in accordance with the local information profile.

Abstract: A processor (202) delays (906) a baseband digital signal by a symbol duration, thereby generating a delayed baseband digital signal. The processor adds (908) the baseband digital signal to the delayed baseband digital signal, thereby generating a summed signal; and divides (910) the summed signal by two, thereby generating a threshold signal. The processor also delays (912) the baseband digital signal by one-half the symbol duration, thereby generating a half-delayed signal; and subtracts (914) the threshold signal from the half-delayed signal, thereby generating a candidate signal. In addition, the processor searches (916) for a zero crossing in the candidate signal, and generates (918) a pulse in response to finding the zero crossing.

Abstract: A first transceiver (122) detects (402) a need for desired information available from a network server (108). In response to detecting the need and before contacting the network server, the first transceiver attempts (412) to obtain the desired information from another transceiver of a plurality of wireless transceivers near the first transceiver, thereby potentially eliminating a necessity for the first transceiver to contact the network server to obtain the desired information.

Abstract: A processing system (206) defines (302) a plurality of bins (230) within a sliding time window, each bin for storing a total transmit duration of a predetermined number of frames assigned to each bin. The processing system then determines (310) a mean transmit duration per frame for a next one of the plurality of bins to be processed. The processing system subtracts (312) the mean transmit duration per frame from the total transmit duration of the one of the plurality of bins, when a next frame begins to be processed; and calculates (314) a transmit duty cycle for the sliding time window, the transmit duty cycle calculated as if a requested transmit duration for the next frame were to be allowed. The processing system also delays (316) a transmission of the next frame, when the transmit duty cycle is greater than a maximum allowable transmit duty cycle.

Abstract: A processor (1104) receives a baseband signal including a plurality of symbols, and determines (1002) a maximum modulation level and a minimum modulation level in the baseband signal through a modified self-organizing map clustering technique. The processor initializes (1008) a plurality of clusters (700, 800) corresponding to the plurality of modulation levels, based upon the maximum and minimum modulation levels; and processes (1010), through a modified adaptive k-means clustering technique, a symbol value corresponding to each of the plurality of symbols by updating (1012) parameters maintained for a cluster of the plurality of clusters, the cluster having a cluster mean value within a modulation-specified distance from the symbol value. The processor calculates (1014) a plurality of statistical values from the parameters maintained for the plurality of clusters, and classifies (1016, 1018, 1020) the baseband signal, based upon the plurality of statistical values and the parameters.

The controller transmits (406) the channel pattern to a processor (310) which processes received inbound traffic. The processor then manages (412) the inbound traffic in accordance with the channel pattern.

Abstract: A messaging system transmits to a subscriber unit (122) on a plurality of channels (410) operating concurrently. The system transmits (1108) control information for the subscriber unit on a control channel assigned to the subscriber unit, and transmits (1110) a personal message fragment intended for the subscriber unit on a first channel. The system also transmits (1112) a group-call message fragment that may be intended for the subscriber unit on a second channel. Before transmitting, the system schedules (1106) the transmission such that the probability that the personal and group-call message fragments will overlap temporally with one another and that either of the fragments will overlap temporally with the control information is reduced.
