Abstract: PROBLEM TO BE SOLVED: To reduce a setup time of a dispatch call. SOLUTION: In a CDMA (code division multiple access) wireless communication system 200, a dispatch call can be established between two CDMA mobile stations 202, 226, or between other mobile stations and the CDMA mobile station, or between a CDMA mobile station and a computer 236 located outside of the wireless system. To reduce the delay normally associated with call set up in a CDMA system, a dispatch processing network is provided in addition to a telephony switch. Dispatch calls and call set up requests are routed to the dispatch processing network from the radio access network which includes base stations 204, 206. Once a dispatch call request is made, while the dispatch processing network begins setting up a traffic channel for the originating mobile communication device, the target is also paged, and upon responding, set up on a traffic channel.

Abstract: PROBLEM TO BE SOLVED: To provide various embodiments for establishing a group call session serially. SOLUTION: After receiving a serial group call request from a remote unit 101, fixed network equipment 201 selects a first subset of members 260 from the targeted group 250 of units and signals those members to join the group call session. Various techniques for selecting the first subset may be employed depending on what system benefits are desired. A second subset of members 270 from the targeted group of units is also selected and signaled to join the session. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for the assignment of slot cycle to reduce the time required for making a dispatch call. SOLUTION: To address the need for a dispatch mobile (303, 305, 307) to more quickly make a call, in the preferred embodiment of the present invention those remote units (302, 304, 306, 308) operating in a dispatch mode receive a first slot cycle, while those remote units (303, 305, 307) not operating in a dispatch mode receive a second slot cycle. The second slot cycle is greater than the first slot cycle, so that those remote units (303, 305, 307) operating in dispatch mode 'wake up' during the slot cycle normally utilized for interconnect calls.

Abstract: PROBLEM TO BE SOLVED: To improve network access through multistage signaling.
SOLUTION: A network node generates a shared indicator code to show at least one of emergency call access and group call access occurring in a sector (12). When an MS performs emergency access, the MS transmits an access signal by both of the shared indicator code and a randomly selected code (13). Thereby, it is noticed more quickly that there is at least one MS in the sector. Once the fact that such access is occurring in the sector is identified, a network performs at least one of things that the network supplies additional access resources, that the network estimates the number of the MS transmitting based on received power on the indicator code, that the network starts backing off non-emergency traffic, and that the network starts transmitting communication without waiting for an authentication to be completed (14).

Abstract: PROBLEM TO BE SOLVED: To reduce a jitter buffer delay while reducing interference to other communication.
SOLUTION: A wireless communication system transmits data over a first link from a first mobile station to an infrastructure at a first speaker link power level, and over a second link from the infrastructure to a second MS at a first listener link power level, during a first time period. Each of the first power levels is designed to avoid the need for retransmissions of erroneously received data. Upon expiration of the first time period, data is transmitted over the first and second links at reduced power levels and retransmissions of erroneously received data can be made. Error rate targets may be adjusted after expiration of the first time period. In addition, the power levels and error rate targets may be individually adjusted on a link-by-link basis based on the RF loading of each link or based on error measurement criteria determined for each link.

Abstract: A communication device (202) converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal (214) subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted (278) via a wireless link. On a receive side (260), a receiving (260) communication device (250) receives the transmitted (230), encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase (234) used to encrypt the symbol at the transmit side.

Abstract: A packet data communication system that includes a mobile station having a jitter buffer and a wireless infrastructure having a base site serving the mobile station controls a size or dept of the jitter buffer. The size or depth is controlled based on a number of retransmissions of erroneously received data employed by the system, a radio frequency load of the base site, and a round trip time period for acknowledgments and corresponding retransmissions. The jitter buffer size may be further controlled by use of a supplemental channel to expedite the transmission of data and thereby fill up the jitter buffer more quickly and by reduction of a waiting period for retransmission of the acknowledgments, thereby reducing the round trip time period.

Abstract: In a CDMA wireless communication system (200) a dispatch call can be established between two CDMA mobile stations (202, 226), or between other mobile stations and the CDMA mobile station, or between a CDMA mobile station and a computer(236) located outside of the wireless system. To reduce the delay normally association with call set up in a CDMA system, a dispatch processing network (128, 144) is provided in addition to a telephony switch (118). Dispatch calls and call set up requests are routed to the dispatch processing network from the radio access network (110) which includes base stations (204, 206). Once a dispatch call request is made, while the dispatch processing network begins setting up a traffic channel for the originating mobile communication device, the target is also paged, and upon responding, set up on a traffic channel. The concurrence of establishing radio links with the target and originating communication devices substantially reduces dispatch call set up time.

Abstract: Apparatus and method for performing radio environment reporting on a reverse common signaling channel. When a dedicated RF connection between a remote unit (RU) ( 118 ) and infrastructure equipment ( 109 ) is being released, the RU receives a first message from the infrastructure instructing the RU to perform occasional pilot strength reporting on the reverse common signaling channel (r-csch) while the RU is in the idle state. In the preferred embodiment, the pilot strength reporting is limited by a maximum number of reports and/or a time limit to preserve battery life and prevent r-csch congestion in the system. Preferably, a Radio Environment Report Message, referred to generally herein as a second message, carries radio environment information (REI), such as pilot strength and phase of the best pilots measured, and helps the infrastructure both with tracking the RU location and with selecting a strong set of pilots for channel assignment.
