摘要： A server (101) designates and assigns each of a plurality of communication devices to at least one of a plurality of groups. The server (101) prepares a communication having presence information corresponding to a status of the communication devices in the group; determines network infrastructure device(s) serving the group; and transmits, at a pre-determined time, the communication to the network infrastructure device(s). A network infrastructure device (103a-c, 105a-f) receives the communication and transmits, as a common channel signal during the pre-determined time, a signal with the presence information. A communication unit (107a, 107b, 107c) receives an indication of the pre-determined time; transmits, at an interval proximate to the pre-determined time, a signal indicating the communication device's status; and receives, at the pre-determined time, the signal with the presence information.

摘要： To address the need for a communication unit, a communication infrastructure, and method that extend battery life, the present invention provides a special page message (200) that is transmitted toward the beginning of a paging slot to indicate what groups of messages will be transmitted in the paging slot. This message allows communication units (e.g., 102–104) to determine near the beginning of the paging slot whether they need to continue monitoring the paging slot for messages or pages directed or of interest to them. The message also allows communication units that continue monitoring the paging slot to determine when they can cease the monitoring. Thus, communication units can return to a power-saving sleep mode more quickly than the prior art.

摘要： To address the need for a communication unit, a communication infrastructure, and method that shorten call-setup time while still providing the benefit of the QPCH, the present invention provides a communication unit (e.g., 103) that sends a page response before receiving a page message from the communication infrastructure, based on the values of the QPCH indicators. This “preemptive” page response shortens call-setup time. Because several communication units may send page responses before verifying whether they specifically are being paged, the infrastructure (e.g., 108-110) determines which page responses are valid (and processes them further) and which are false (and discards them).
摘要翻译： 为了解决对通信单元的需求，通信基础设施和方法，其在仍然提供QPCH的优点的同时缩短呼叫建立时间，本发明提供了一种通信单元（例如，103），其在接收之前发送寻呼响应 基于QPCH指示符的值，来自通信基础设施的页面消息。 此“抢占式”页面响应缩短了呼叫建立时间。 因为几个通信单元可以在验证它们是否被特定地被寻呼之前发送寻呼响应，所以基础设施（例如，108-110）确定哪些页面响应是有效的（并进一步处理），哪些是错误的（并丢弃它们）。

摘要： Various embodiments are described for signaling an ad-hoc group of mobile units (MUs). The ad-hoc group may be a group of MUs for which signaling awaits transmission via a wireless communication resource (111). Signaling such a group involves deriving a mobile unit group identifier (MUGI) by combining individual mobile unit identifiers (MUIs) of the targeted ad-hoc group. The individual MUIs are either an identifier of each MU or derived from an identifier of each MU. The derived MUGI is then included in combined signaling that is transmitted (by RAN 121, e.g.) via the wireless communication resource. A receiving MU (101) determines whether the MUGI could have been derived from its MUI in combination with at least one other MU's MUI. When it determines that the MUGI could have been derived from its MUI, the receiving MU processes the signaling as directed to itself.

摘要： A communication system provides network-based battery power management that may be transparent to a user of a mobile station (MS). When one or more elements of a network of the communication system determines that the MS is operating at a low power supply charge level and/or has experienced a significant change in a charging level of the power supply, the one or more network elements may arrange for postponement of delivery of a delay-tolerant service to the MS or for adjustment of one or more of a characteristic of a service provided to the MS and a parameter of a radio communication with the MS, including restoration of full services to an MS whose power supply charge level has been restored.

摘要： Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (104), such as an enhanced ECAM, and service connection messaging (108), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs (110) earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VoIP) between a BS (201) and an MS (210) are described.

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 call setup method (50) makes an early detection if a mobile call is to be placed (52). The mobile unit (10) then checks to insure that the battery life of the mobile unit is above a threshold level (56). If the battery level is sufficient, the mobile unit begins an early scan for an RF acquisition message (60).
