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 system provides separate subscription keys for a non-subscriber version of a broadcast-multicast flow and a subscriber-only version of the flow, thereby controlling who may store or render the flow. In one embodiment, separate subscription keys may be assigned to a same broadcast-multicast flow. The communication system may then switch the keys used to encrypt the flow, or may use different keys to encrypt different copies of the flow, in order to allow at least non-subscribers to view one version of the flow and only subscribers to view another version of the flow. In another embodiment, the communication system may assign a group subscription key to a group of broadcast-multicast flows that is separate from the keys assigned to each individual flow. The group subscription key may then be used to encrypt a non-subscriber version of any broadcast-multicast flow in the group of broadcast-multicast flows.

摘要： A communication system provides one or more of congestion information and subscriber information to a broadcast applications server when the server receives a request to start a broadcast-multicast service in a coverage area. By providing the one or more of congestion information and subscriber information to the server, the server is able to make an informed, intelligent decision concerning blocking, unblocking, downgrading, or upgrading a broadcast-multicast flow of multiple broadcast-multicast flows requested for delivery to, or currently delivered to, the coverage area via a serving base station, and/or whether to add a new broadcast-multicast flow to the broadcast-multicast flows delivered to the coverage area.

摘要： The present invention provides an apparatus and method for operating in reduced slotted mode. Following the release of the traffic channel, a mobile station (102) and base station (108) operate with a shorter slot cycle governed by a reduced slot cycle index value. The mobile station and base station operate using the reduced slot cycle index value until a particular time occurs governed by a reduced slotted timer value or for a period of time governed by the reduced slotted timer value. The invention provides faster call setup for mobile station terminated calls, without requiring registration with a MSC (110) to change between the reduced slot cycle index value and the registered slot cycle index value.

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： A method and system for selecting a target cell for handover of user equipment in a Long Term Evolution (LTE) communication system are described. In accordance with the method, a serving cell: determines virtual channels supported by each of a plurality of neighboring cells; determines a set of virtual channels of interest to a UE; selects a subset of the neighboring cells, which supports at least one virtual channel in the set of virtual channels of interest to the UE; modifies handover behavior, and uses results of the modified handover behavior to select one of the neighboring cells, from the subset, as a target cell for handover of the UE.
