Abstract: A computing system in which a user of a client system can continue with submission of an additional request while an application framework processes prior requests. In an embodiment, when a request is received, the resource requirements for processing the request are determined. If the resource requirements exceed a threshold, the request may be processed in the background. The user can continue issuing additional requests. After completion of processing of a request, the availability of the results may be notified in a pre-specified portion of a window from which the user is interacting with the application framework. The user may conveniently request the results by clicking on a portion of the displayed message.

Abstract: Techniques for performing admission control based on quality-of-service (QoS) performance in a wireless communication network are described. QoS performance (e.g., delay or throughput performance) of admitted data flows may be determined. Whether to admit or reject a new data flow may then be determined based on the QoS performance of the admitted data flows. The admitted and new data flows may have delay bounds. The QoS performance of the admitted data flows may be given by a measured sector delay, which may be determined based on actual delays of packets. A measured flow delay for each admitted data flow may be determined based on delays of packets for that flow. The measured sector delay may then be determined based on the measured flow delays for all admitted data flows. The new data flow may be admitted if the measured sector delay is less than a delay threshold.

Abstract: A method for converting packet-based voice data of a first format directly to packet-based voice data of a second format, and vice versa. Data from networks using non-compatible packet-based voice technologies, for example, VoATM and VoIP, are interworked for direct conversion. Connection is set between an edge gateway of a first voice packet network, having data in a first format, and an interworking unit (IWU). Another connection is set between this IWU and an edge gateway of a second voice packet network, having data in the second format. The IWU is controlled by a single call agent that co-ordinates the conversion, at the IWU, between the two packet formats. Because it has this capability, this call agent is also called the “conversion server”. This call agent may be identical to the call agent used to control one or both edge gateways that use different packet based technologies.

Abstract translation: 一种用于将第一格式的基于分组的语音数据直接转换为第二格式的基于分组的语音数据的方法，反之亦然。 使用不兼容的基于分组的语音技术的网络（例如VoATM和VoIP）的数据可以互相直接转换。 在具有第一格式的数据的第一语音分组网络的边缘网关和互通单元（IWU）之间设置连接。 在该IWU和具有第二格式的数据的第二语音分组网络的边缘网关之间设置另一连接。 IWU由单个呼叫代理控制，协调IWU在两种数据包格式之间的转换。 由于具有此功能，此呼叫代理也称为“转换服务器”。 该呼叫代理可以与用于控制使用不同的基于分组的技术的一个或两个边缘网关的呼叫代理相同。
