摘要： Embodiments of the present invention are directed to providing a method and system for call admission control for a Long Term Evolution (LTE) network shared between a plurality of user classes, such as, for example, a public safety user class and a consumer user class. An admission control module oversees the call admission process based on a specified policy profile. When there are insufficient resources in the network to support an incoming call, the admission control module will consult with a preemption module to determine whether, by preemption of lower priority calls, enough resources can be recovered to support the incoming call.
摘要翻译：本发明的实施例涉及提供一种用于在多个用户类（例如公共安全用户类和消费者用户类）之间共享的长期演进（LTE）网络的呼叫准入控制的方法和系统。准入控制模块根据指定的策略配置文件来监督呼叫准入进程。当网络资源不足以支持来电时，准入控制模块将咨询抢占模块，以确定通过优先级较低的呼叫是否可以恢复足够的资源来支持来电。

摘要： A method and system for group call control in a broadband wireless network. A group call (push-to-talk) server initiates and regulates group call communication sessions. A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator. If not, regular call resources are allocated, if available. If so, it is determined whether another group member is attached to the base station. Group call resources are then reserved, if available, based on this determination. The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.

摘要： Embodiments of the present invention are directed to providing a method and system for call admission control and preemption of multiple bit-rate applications in a digital communication system. Multiple bit-rate applications such as streaming video can specify a Quality of Service (QoS) profile having multiple levels. When there are insufficient resources in the network to support an incoming multiple bit-rate call, the system determines whether, by reducing the bit-rate of the incoming call or by preemption of lower priority components of existing calls, enough resources can be recovered to support the incoming call.
摘要翻译：本发明的实施例涉及提供一种用于数字通信系统中的多个比特率应用的呼叫接纳控制和抢占的方法和系统。诸如流视频的多个比特率应用可以指定具有多个级别的服务质量（QoS）简档。当网络资源不足以支持传入的多个比特率呼叫时，系统通过减少呼入呼叫的比特率或者通过抢占现有呼叫的低优先级组件来确定足够的资源可以恢复到支持来电。

摘要： For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.
摘要翻译：对于LTE中的语音流量，持续调度（PS）或半永久（SPS）调度将是最小化信令消息的首选方法。在PS或SPS中，资源以规则的间隔（例如，每20毫秒）预先分配给UE 402。在每个时隙，UE将通常发送以ISSI分组编码的IMBE帧。在ISSI中，其他数据流与IMBE帧复用，因此分组大小根据其在超帧内的位置而变化。对于PS或SPS，eNodeB必须分配足够的资源来支持最大的数据包。因此，当数据包不是最大的大小时，有空余的容量。示例性实施例指定使用备用容量来传送数据的方式。
