    • 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.
    • 通信系统为广播组播流的非订户版本和流的仅用户版本提供单独的订阅密钥,从而控制谁可以存储或呈现流。 在一个实施例中,可以将单独的预订密钥分配给相同的广播多播流。 然后,通信系统可以切换用于加密流的密钥,或者可以使用不同的密钥来加密流的不同副本,以便允许至少非订户查看流的一个版本,并且仅允许订阅者查看另一个版本 的流量。 在另一个实施例中,通信系统可以将组订阅密钥分配给与分配给每个单独流的密钥分离的一组广播 - 多播流。 组订阅密钥然后可以用于加密广播组播流组中的任何广播 - 多播流的非订户版本。

    • 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.
    • 描述了各种实施例用于发送移动单元(MU)的自组织组。 自组织组可以是一组MU,其信令等待经由无线通信资源(111)的传输。 信令这样的组涉及通过组合目标特设组的各个移动单元标识符(MUI)来导出移动单元组标识符(MUGI)。 单个MUI是每个MU的标识符或从每个MU的标识符导出的。 导出的MUGI然后被包括在经由无线通信资源(例如,RAN 121)发送的组合信令中。 接收MU(101)确定MUGI是否可以与其至少一个其他MU的MUI结合从其MUI导出。 当确定MUGI可能是从其MUI导出时,接收MU按指示自身处理信令。

    • 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.
    • 本发明提供了一种以缩小的时隙模式操作的装置和方法。 在业务信道的释放之后,移动站(102)和基站(108)以更短的时隙周期操作,由缩短的时隙周期指数值控制。 移动台和基站使用减少的时隙周期指数值进行操作,直到特定时间由减少的时隙定时器值或由缩短的时隙定时器值来控制的时间段来控制。 本发明为移动台终止的呼叫提供了更快的呼叫建立,而不需要向MSC(110)注册,在缩短的时隙周期索引值和注册的时隙周期指数值之间进行改变。
