摘要： A User Equipment (UE) for handling voice or video calls, such as for example a smartphone, PC, laptop, tablet, etc, has a voicemail client integrated in its OS, or in the form of an app, configured to receive an incoming call message causing an alert about the incoming call for at most a pre-set no-answer period of time, after which, if the call is not answered, the call being set to be completed from the calling party towards a network-based voicemail center, and before the expiry of the pre-set no-answer period of time, to answer the incoming call, causing the call to be established between the calling party and the UE's voicemail client, wherein the call is not completed towards the network-based voicemail center. The voicemail client is further configured to play a greeting message for the calling party over the call with the calling party, record a voice message from the calling party, and alert the user of the UE about the voicemail message, using the UE's voicemail client. Voicemail messages are thus saved and accessed locally on the UE avoiding the signaling to a network-based voicemail client.

摘要： Methods, terminal and a data center gateway are provided for allowing efficient debugging and troubleshooting of data session encrypted with Perfect Forward Secrecy (PFS) encryption techniques such as for example the Transport Layer Security (TLS) protocol version 1.3. Embodiments of the invention allow the user terminal to authorize a data center gateway to persistently store one or more encryption keys associated with the data session for use to access the recorded data session and troubleshooting it after the session ended, when faults are detected. When a fault is detected, the user terminal provides authorization to the gateway to persistently store the data session along with one or more encryption key(s). With this, the gateway allows for the data session to be later decrypted and faults to be investigated despite the data session being encrypted with PFS techniques.

摘要： Techniques are disclosed for providing remote access to virtual machine (VM) serial port interfaces of cloud applications through automated serial port concentration techniques. A coordination agent can be deployed, and a virtual serial port concentrator (VSPC) module can be deployed along with VMs of a cloud application. The coordination agent can determine that the cloud application has entered a running state, determine an IP address of the VSPC module, and cause a serial port interface of each VM to be coupled with the VSPC module. The VSPC module can allocate local ports for the VMs and report the port numbers to the coordination agent to be provided to a client. The client can transmit data for a serial port connection to a particular VM through the VSPC module by sending the traffic to the IP address of the VSPC module at a particular port associated with the particular VM.
摘要翻译：公开了通过自动化串行端口集中技术来远程访问云应用的虚拟机（VM）串行端口接口的技术。可以部署协调代理，并且可以与云应用程序的VM一起部署虚拟串行端口集中器（VSPC）模块。协调代理可以确定云应用已经进入运行状态，确定VSPC模块的IP地址，并使每个VM的串口接口与VSPC模块耦合。 VSPC模块可以为VM分配本地端口，并将端口号报告给要提供给客户端的协调代理。通过将流量发送到与特定VM相关联的特定端口处的VSPC模块的IP地址，客户端可以通过VSPC模块将用于串行端口连接的数据发送到特定VM。

摘要： A system configuration is partially validated in response to requested changes to the system configuration. First, a reduced set of constraints is identified among a plurality of constraints of the system configuration. The reduced set of constraints place restrictions on attribute values and relations of changed entities to which the requested changes are applied. Each constraint of the reduced set is categorized based on leadership information that indicates an impact that a changed entity has on another entity with respect to the constraint. Each categorized constraint of the reduced set is validated to determine whether to accept, reject or modify the system configuration having the requested changes.

摘要： A method and apparatus for routing transmit and receive signals in a radio RF front end. According to one aspect, the disclosure provides a multiplexer method and apparatus for routing transmit signals to an antenna and routing amplified receive signals to a receiver. The multiplexer includes a first hybrid coupler having a first frequency response and at least one other hybrid coupler having a second frequency response. The at least one other hybrid coupler is coupled to the first hybrid coupler by a first and second splitters each cascaded with a set of amplifying circuits for balanced amplification. In some embodiments, the second frequency response complements the first frequency response to increase cancellation of two signals arriving at an output port of the at least one other hybrid coupler from two different paths through the first and the at least one other hybrid couplers.

摘要： A system is adapted to generate a configuration for a service provider system to provide a highly available (HA) service. The system first identifies type stacks that provide the HA service and one or more component types in each type stack. Each type stack is a combination of prototypes that describe features and capabilities of available software providing the HA service. The system estimates, for each component type in the type stacks, a mean-time- to-recover (MTTR) of the HA service based on time for completing an actual recovery action in response to a component failure. The system further estimates service availability provided by each type stack based on the MTTR and a mean-time-to-failure (MTTF) of each component type in the type stack. The system then eliminates one or more of the type stacks that do not satisfy a requested service availability before proceeding to subsequent steps of configuration generation.

摘要： In one aspect, the teachings herein provide point-to-point communication between all the virtual machines (VMs) belonging to the same tenant in a cloud-based virtual network environment without using any intermediate routing functions, and while providing full virtualization at the L2 and L3 levels. That is, the approach preserves completely isolated address spaces for each tenant at both L2 and L3 levels and supports multiple subnets for each tenant, and thereby allows tenants to define their own virtual networks without requiring the addition of expensive centralized routing and without requiring inter-subnet communications for the same tenant to traverse sub-optimal paths, as happens with software- based routers implemented in one of the VMs belonging to the tenant. Moreover, the methods and apparatuses taught herein provide a distributed solution for communicating between subnets belonging to the same virtual or logical network, thereby avoiding single-point-of- failure issues and offering improved scalability.
摘要翻译：在一个方面，本文的教导提供了属于基于云的虚拟网络环境中的相同承租人的所有虚拟机（VM）之间的点对点通信，而不使用任何中间路由功能，并且在L2提供完全虚拟化和L3级别。也就是说，该方法为L2和L3级别的每个租户保留完全隔离的地址空间，并为每个租户提供多个子网，从而允许租户定义自己的虚拟网络，而不需要增加昂贵的集中式路由，同一租户的子网通信可以遍历次优路径，就像在属于租户的其中一个虚拟机中实现的基于软件的路由器一样。此外，本文教导的方法和装置提供用于在属于相同虚拟或逻辑网络的子网之间进行通信的分布式解决方案，从而避免单点故障问题并提供改进的可扩展性。
