  • Publication number: 20160085576
    Abstract: Concepts and technologies are disclosed herein for service creation and management. A processor can detect an event relating to a service, and access a service creation database to identify a recipe associated with the service. The recipe can define a resource to be used to provide the service. The processor can access an inventory to determine if the resource is available, identify a service control to control the service, instruct an infrastructure control to allocate virtual machines to host components of the service, and issue instructions to the service control. The instructions can instruct the service control to load service functions to the virtual machines.

  • Patent number: 9288657
    Abstract: A separate domain selection function is utilized as the first function in a communication path for a communication that is to be connected to a user device registered in a first network or a second network. If a result of the domain selection function indicates call control should be maintained by first network (e.g., user device is registered with first network or a network with which first network has a control relationship), call control of the communication remains with first network. If the result of the domain selection function indicates the user device is registered with second network, call control is suspended by the first network, which allows the communication to bypass the first network.
