Abstract: To address the need for reducing call setup time without degrading the originator's service, a RAN (103) transmits a channel assignment message in a paging slot monitored by a target unit (113). The target unit responds to this channel assignment page indicating its availability and location within the RAN coverage area. The RAN then indicates the availability of the target unit to the calling unit (120) that originated the service request. In this way, the originator is able to proceed with the communication service, while the target completes its call setup.

Abstract: Logic circuitry (409) constantly monitors a transmitter (410) to determine if the transmitter (410) is idle. Logic circuitry (409) suppresses all NAKs until data and other channel information is not being transmitted by the transmitter (410) and RF resources are not scarce. Additionally, logic circuitry (409) suppresses all NAKs until a predetermined number of NAKs has been buffered by the logic circuitry (409). More particularly, logic circuitry (409) determines when a number of NAKs will sufficiently fill an over-the-air frame. Once the predetermined number of NAKs has been collected, the logic circuitry (409) will generate the appropriate NAKs.

Abstract: An idle frame counter is not reset after retransmission of a data frame. Additionally, if a non-acknowledgment (NAK) is received for the last data frame sent, then no more idle frames are transmitted. Finally, an Idle Acknowledgment (ACK) is transmitted when an idle frame has been received with a sequence number equal to the sequence number of the next new data frame expected.

Abstract: An apparatus and method for optimizing the transition of a Mobile Station (MS) between states of operation for packet data service. An RF connection is established between the MS and Base Site Equipment (BS) for the transmission of data packets. After a period of inactivity of transmission, the RF connection is released and the BS provides the MS with the equipment identifier of the network element that will maintain the connection with a PDSN. The MS retains the identifier while in the Dormant state and a new Semi-Dormant state and sends the identifier to the BS when requesting reactivation. In the Dormant state, the network element maintaining the connection to the PDSN is the PCF. In the Semi-Dormant state, the network element maintains the connection between to the PDSN is the SDU. When the BS has data to transmit to a MS in the Semi-Dormant state, it channel assigns the MS into the Active state according to pilots reported in RF Measurement Report Messages previously received from the MS.

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: Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (101), fixed network equipment (FNE) (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. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit (or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.

Abstract: At least one transmission condition associated with making a transmission of pre-cache data over a transmission leg (112 or 114) of a network is obtained. A priority for transmitting the pre-cache data is determined using the transmission condition.

Abstract: Se describen varias modalidades para establecer una sesion de llamada de grupo en serie. Despues de recibir una solicitud de llamada en grupo en serie desde una unidad remota (101), el equipo de red fijo (FNE) (201) selecciona un primer subconjunto de miembros para unirse a la sesion de llamada de grupo; varias tecnicas para seleccionar el primer subconjunto se puede emplear dependiendo de cuales son los beneficios del sistema que se desea; un segundo subconjunto de miembro (270) desde el grupo objetivo de unidades tambien se selecciona y se senaliza para unirse a la sesion; este segundo subgrupo tambien se puede utilizar para invitar unidades adicionales y asi poder lograr un maximo numero de participantes en el grupo. Alternativamente, el segundo subgrupo se puede utilizar para invitar una unidad diferente (o unidades) a participar. Esto puede ser disparado por la solicitud del usuario para invitar otro subconjunto de sesion de grupo, como podria ocurrir cuando el usuario no tiene la capacidad de resolver el asunto en particular a la mano o inmediatamente con los miembros de grupo del primer subconjunto.

Abstract: A method (300) and communication device (106) capable of streamlining call setups to a wireless mobile unit (102) may include a transceiver (520) and a controller (502). In various embodiments of the invention, the controller detects (302) a modified request for a communication resource, optionally monitors (304) a communication system loading parameter, and sends (406 or 408) an assignment for a larger than anticipated allocation of the communication resource upon detecting the modified request or when the system loading parameter falls below a predetermined threshold. The controller may also receive (410) via the larger than anticipated allocation of the communication resource both an anticipated initial data transmission and an initial user data transmission in a first data transmission from the mobile wireless unit.

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.
