    Abstract: According to one method for preserving stable calls during failover, during a dialog between two user endpoints, a determination is made whether a standby call processor has become operational, such as when a corresponding primary call processor is in fault. Responsive to determining that the standby call processor has become operational, a signaling protocol message is received from a requester. A determination is made whether the message includes an in-dialog signaling protocol request. Responsive to determining that the message includes the in-dialog request, a determination is made whether a call state associated with the dialog is found in memory. Responsive to determining that the call state associated with the dialog is not found in memory, a non-call terminating error response is made responding to the in-dialog request. The non-call terminating error response may cause the requester to terminate the in-dialog request but not terminate the dialog.

    Abstract translation: 根据用于在故障切换期间保持稳定呼叫的一种方法,在两个用户端点之间的对话期间,确定备用呼叫处理器是否变得可操作,例如当相应的主呼叫处理器处于故障时。 响应于确定备用呼叫处理器已经可操作,从请求者接收到信令协议消息。 确定消息是否包括对话信令协议请求。 响应于确定消息包括对话请求,确定是否在存储器中找到与对话相关联的呼叫状态。 响应于确定与存储器中没有找到与对话相关联的呼叫状态,响应对话请求而产生非呼叫终止错误响应。 非呼叫终止错误响应可能导致请求者终止对话请求,但不终止该对话。

    Abstract: Aspects of the subject disclosure may include, for example, a device in which a processing system defines service attributes for a function of an internet multimedia subsystem (IMS) core; the function is dedicated for providing a service to a user endpoint (UE) device. The processing system facilitates constructing a resource profile of the IMS core that includes the function; registering the function at a network repository function (NRF) associated with the IMS core; discovering the function from the NRF; obtaining a service requirement of the UE; and matching the service requirement with the service attributes in accordance with matching criteria. Other embodiments are disclosed.

    Abstract: Concepts and technologies are disclosed herein for message flow management for virtual networks. A processor can identify a target virtual network function instance that is to be taken offline. The processor can change a status associated with the target virtual network function instance to indicate it being taken offline. The processor can start a graceful shutdown timer to trigger shutdown of the target virtual network function instance. The processor can identify external interfaces and a peer network function that identifies the target virtual network function instance as a next hop. The processor can obtain, for the target virtual network function instance and the peer network function instance, a snapshot that identifies configuration data for the target virtual network function instance and the peer network function instance and can generate a command to trigger a shutdown of the target virtual network function instance.

    Abstract: A system for deploying Voice over Internet Protocol (VoIP) services is provided. A system that incorporates teachings of the present disclosure may include, for example, a Call Session Control Function (CSCF) having a controller element to receive a Session Initiation Protocol (SIP)message from an originating communication device requesting communications with a terminating communication device, and establish an Internet Protocol (IP) connection between the originating communication device and an advertisement media system to present at the originating communication device an advertisement message that replaces a ringback tone associated with the terminating communication device. Additional embodiments are disclosed.

    Abstract: A method and apparatus for controlling a call volume for an office that serves as a protecting site for another office in a packet network are disclosed. For example, the method collects one or more customer registration counts from one or more session border controllers located in a first office, determines if the one or more customer registration counts have reached or exceeded a threshold. The method directs all of said one or more session border controllers located in said first office to enact one or more throttling rules if the one or more customer registration counts have reached or exceeded the threshold.
