    摘要: A system and method for establishing communication with a target mobile station (312) initiated in part by establishment of a traffic communication channel with a target mobile station (312). Responsive to establishing the traffic communication channel, a message is sent by the target mobile station (312) substantially immediately to a dispatch server (304) via the traffic communication channel. The message comprises information indicating acceptance of a push-to-talk (PTT) request.

    摘要: A communication device 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 subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted via a wireless link. On a receive side, a receiving communication device receives the transmitted, encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase used to encrypt the symbol at the transmit side.

    摘要: During the course of a push-to-talk talkgroup wireless communication, decisions (21) are made regarding possible subsequent push-to-talk communication needs for the group. Based at least in part upon such decisions, a network location is identified (22) to provide talker arbitration support for this talkgroup. In one embodiment the identified network location can comprise a mobile station, such as a mobile station that comprises a member of the talkgroup. In a preferred embodiment, the talker arbitration capability is then assigned (24) to the identified network location.

    摘要: A method (600) and apparatus (700) for reducing delay associated with a call set-up for a call between an originating communication unit (120) and a target communication unit (121–124) in a radio access system (RAS) (101) is described. A call is initiated with a target communication unit prior to a channel assignment. A first latency (411) between an initiation time and a time when the target is capable of receiving a notification of the call on a first channel (410) is estimated and a second latency (421) between the initiation time and a second time when the target is capable of receiving the notification on a second channel (420) is estimated. Addresses associated with the target can be sent to the radio access system on the first channel or the second channel based on the estimated first latency and the estimated second latency.

    摘要: The present embodiments provide apparatuses, methods and systems for use in notifying a remote communication device when a local wireless device loses its wireless link. In some embodiments, a method detects when a wireless connection is lost with a first communication device, identifies a second communication device that is communicating with the first device, and notifies the second device of the lost link. In some implementations, the notification of the lost link is supplied while the method provides batch communications. Some embodiments provide voice communications, where a remote device is notified when a local device loses its wireless connection. The second device can be determined by querying a server. The notifying can include forwarding an in-band tone, and/or generating a real time protocol packet. In some embodiments, the loss of the link is detected through a radio access network, a packet control function, and/or a mobile switching center.

    摘要: 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.

    摘要: A stream of packets is monitored. When a first packet in the stream of packets is detected to be destined for a target mobile station (110), the first packet is intercepted. Subsequently, a small initialization packet is sent to the target mobile station (110). The small initialization packet structured to inform the target mobile station (110) of an identity of an originating application that is initiating a communication session with the target mobile station (110).

    摘要: The need to decrease paging-related delays in wireless systems (100) is addressed by embodiments herein. A RAN (201) anticipates that an MS (120) is likely to be a target of communication not yet initiated. In one embodiment, a traffic channel is assigned to the MS, when a loading level of a serving cell of the MS is below an assignment threshold. This avoids paging-related delays for the MS should the MS become a target of communication. In another embodiment, the MS is signaled to transition to at least one operational mode in which paging-related delays for the MS are reduced. Such modes include a semi-dormant mode, an unslotted mode, a control hold mode, a speculative scanning mode, and a reduced slot cycle index (RSCI) mode. This allows the MS to begin participating in communication more quickly than it otherwise would, should communication targeting the MS be initiated.

    摘要翻译: 通过本文的实施例来解决在无线系统(100)中减少寻呼相关延迟的需要。 RAN(201)预期MS(120)可能是尚未启动的通信目标。 在一个实施例中,当MS的服务小区的负载水平低于分配阈值时,业务信道被分配给MS。 如果MS成为通信对象,则可以避免MS的寻呼相关延迟。 在另一个实施例中,MS用信号通知转换到至少一个操作模式,其中针对MS的寻呼相关延迟减少。 这种模式包括半休眠模式,非锁定模式,控制保持模式,推测扫描模式和缩短的时隙周期索引(RSCI)模式。 如果启动针对MS的通信,则MS可以比其他方式更快地开始参与通信。
