Abstract: In the context of managing wireless network data, access information for a wireless local area network (WLAN) is identified. The access information is accessible over a wireless packet data connection. Based on the access information, a connection is established between a wireless data device and the WLAN.

Abstract: A wireless client in accordance with the invention in range of a suitable wireless access point requests content from a host. The wireless access point routes the initial name resolution request to a local name server that resolves certain host names, actually elsewhere, falsely as addresses on a local network, preferably a private network. The name-server response is sent back to the wireless client, which in turn then sends the request for content to the local address. A router coupled to the wireless access point acts normally to forward the request to a local content server. A local server responds with a copy of content initially synchronized with content available elsewhere. Not all content may be duplicated and some may be unavailable locally. Content may be other than HTML and accessed by various protocols, e.g. FTP, SMTP, Telnet, etc. that utilize hostname resolution services. Wired clients work similarly.

Abstract: A mobile transceiver radio direction-finding sub-system determines the location of a mobile transceiver by receiving information from a locating controller unit that includes tower site geographic location information and radio-frequency protocol information on the target mobile transceiver. After positioning the sub-system within the tower site coverage indicated for the target, the sub-system monitors the target mobile transmitter frequency and utilizes radio direction-finding techniques based on the protocol information to gather bearing and distance information to the target.

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.

The method includes the steps of receiving, at the wireless gateway, a communication message from a first communication network, the communication message including address information associated with a subscriber; storing, by the wireless gateway, the communication message, the communication message being stored in association with the subscriber; and selectively sending, with the wireless gateway using the wireless communication network, at least a portion of the communication message to a wireless device.

Abstract: The generic activation method of a selective call receiver apparatus (122) operating within a messaging system (100) includes providing a selective call receiver (122) having a group address (251) and a unique receiver identification (242) stored in a memory (218). The selective call receiver (122) receives a message addressed to the group address (251) containing the unique receiver identification (242) and programming information (249), and upon receiving the group address (251) and unique receiver identification (242), the method applies the programming information (249) to program the selective call receiver (122).

Abstract: A battery saving interval utilized for communicating with a portable subscriber unit (122) in a radio communication system is dynamically adjusted. An occurrence of a predetermined triggering event associated with the portable subscriber unit is observed (504), and the battery saving interval utilized for communicating with the portable subscriber unit is adjusted (506) in response to the predetermined triggering event, while battery saving intervals of other portable subscriber units in the system are left unchanged.

Abstract: In a telecommunications system, data having a higher sensitivity and data having a lower sensitivity are identified within a data set. The data having a higher sensitivity is encrypted to produce encrypted sensitive data. Thereafter, the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The encrypted data set is then transferred from a sending unit to a receiving unit. Decryption information may be appended to the encrypted sensitive data before the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The decryption information may include an algorithm identifier, a key identifier, and receiver response instructions. At the receiving unit, the data set is decrypted to recover the data having lower sensitivity. A second decryption of the encrypted sensitive information recovers the data having a higher sensitivity.

Abstract: A wireless telephone messaging system determines when link performance is inadequate to provide a live connection and re-directs the call to voice mail, preferably informing the caller of estimated delivery time. A mobile handset and base unit determine the rate at which a voice mail message can be delivered. A wireless base unit conveys the accepted voice mail to a mobile handset using a store-and-forward protocol. A voice mail message can preferably be delivered at a rate lower than that at which speech normally has acceptable quality but which is transmissible over the same link having an inadequate performance characteristic for a live connection. A mobile handset stores a conveyed voice mail message for playback by the handset user.

Abstract: A controller (112) processes (400, 500, 600) an original voice message to detect (602) an original silent portion and to measure (604) an original duration, and the controller creates (620) a modified voice message by replacing (620) the original silent portion with a modified silent portion having a transmission duration. The transmission duration is derived (612, 614, 618) from the original duration, and the transmission duration is shorter than the original duration. The controller then transmits (622) the modified voice message.

Abstract: Methods of and corresponding apparatus for scheduling messages on an operating channel (223) in a selective messaging system (200) for a messaging unit (235) include scheduling a first message, including a channel priority indication (511), addressed to the selective messaging unit on a first channel, and then scheduling a second message for the selective messaging unit on a second channel (225) selected as an alternative operating channel. Analogously at the selective messaging unit a method of selecting an operating channel includes monitoring the first channel for a message addressed to the selective messaging unit; detecting as part of the message the indication; and responsive thereto discontinuing monitoring the first channel and then scan for the second channel.

Abstract: A method for efficient encryption and decryption (100) comprises the steps of encrypting a message (104) at a sending unit which is to be sent to a receiving unit using a message key (106) and appending to the message at the sending unit the message key encrypted (108 and 109) using a receiver's public key (110). Subsequently, a sender's certificate (116) is appended at a first server (302) and extracted at a second server (310). The message key is then decrypted at the receiving unit using a receiver's private key (140) to provide a decrypted message key. Subsequently the message is decrypted using the decrypted message key (142 & 143) and authenticated by comparing a pair of digest (152 and 156).

Abstract: A method of decoding a repeat message made up of repeat message fragments at a selective call receiver (122) using a synchronous wireless protocol having time diversity includes the step of decoding (212) a repeat address N times corresponding to the repeat message. Each of the repeats of the address points to a separate repeat of an encoded vector N times wherein each of the repeats of the encoded vector explicitly points to the beginning of a first of the repeated message fragments. The method further includes the step of decoding (212) the repeated message fragments M times which was received on preassigned time slots.

Abstract: A processing system time compresses a voice message before transmission, and processing system time expands the message after reception. To process the message the processing systems perform at least one of: (a) randomizing the order of a sequence of samples form a silent portion of the message after reception thereof before blending the sequence with a last portion of the expanded message; (b) selecting the sequence of samples from the silent portion of the message after reception thereof, the sequence selected being poorly correlated with the last portion of the expanded message, before blending the sequence with the last portion of the message; and (c) compressing the dynamic range of the message before transmission, by an amount dependent upon the signal-to-noise ratio of the message, and aggressively expanding the dynamic range of the message after reception, by a fixed amount.

Abstract: In a data communication system a first controller (102) selectively retrieves data from a database (316) in a second controller (106). Data corresponding to a plurality of entities is programmed (602) into the database. The data includes a plurality of parameters for each of the plurality of entities. Ones of the plurality of parameters are selectively defined (604) to belong to parameter groups in accordance with a predetermined grouping plan. The first controller generates (612) a request for the data corresponding to one of the plurality of entities from the database, the request further indicating a desired one of the parameter groups. The second controller returns (620) the desired one of the parameter groups corresponding to the one of the plurality of entities, in response to the request.

Abstract: A method and apparatus transmits (400, 500) and receives (600) information as a power hopped direct sequence spread spectrum signal. The information is encoded (402) with a predetermined spreading sequence to produce a direct sequence spread spectrum, or DSSS, signal, and a plurality of simultaneous radio signals operating on a plurality of frequency slots (F.sub.1 -F.sub.10) and modulated by the DSSS signal are generated (404, 406, 504). The output power of individual ones of the plurality of simultaneous radio signals is adjusted (408, 502) periodically according to a predetermined power hopping sequence. The information is received by demodulating (602) and processing (604-620) the signal from at least one of the plurality of frequency slots.

Abstract: A messaging system capable of transmitting messages to receivers which roam between coverage areas. In one configuration, a coverage area (600) is divided into a plurality of zones (605, 610, 615). A single simulcast system identification (SSID) number is assigned which consists of a local identification number which identifies the coverage area (600), a zone identifier which identifies a zone (610) within the coverage area, traffic splitting flags and a frequency. For larger roaming areas, a network is defined as consisting of a plurality of service areas and is identified by network identification information (NID). NID information and/or SSID information along with a priority value is stored in a receiver according to desired coverage and like information is transmitted in the corresponding zone or service area and the roaming pager operates on the frequency having the NID or SSID having the highest priority.
