Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation connected to user equipment, and hosts edge applications that perform one or more mobile network services at the edge of the mobile data network based on the broken out data. When a breakout component is not running a needed edge application, the session for the user equipment may be transferred to a neighboring basestation that is running the needed edge application.

Mobile network services are performed in a mobile data network that includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation connected to user equipment, and hosts edge applications that perform one or more mobile network services at the edge of the mobile data network. When a breakout component is not running a needed edge application, and the needed edge application is running in a neighboring basestation, the breakout component can route the request for the needed edge application to the neighboring basestation via the overlay network. The neighboring basestation processes the request using the needed edge application, then returns the data to the original basestation via the overlay network. The original basestation thus maintains the subscriber session with the user equipment while offloading the work of the needed application to a neighboring basestation.

Mobile network services are performed in an appliance in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. The appliance in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. The appliance has defined interfaces and defined commands on each interface that allow performing all needed functions on the appliance without revealing details regarding the hardware and software used to implement the appliance. The appliance includes overload detection and handling within the appliance. This appliance architecture allows performing new mobile network services at the edge of a mobile data network within the infrastructure of an existing mobile data network.

Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. The breakout component includes a service interface that performs primary control by one system, and backup control by a different system.

A fail-to-wire (FTW) module preserves a primary data path connection from an upstream computer to a downstream computer if there is any kind of failure in a breakout data path to a breakout system. The FTW module provides switches between the incoming data network data and the breakout system such that when the breakout system encounters a failure, the switches are de-activated to bypass the breakout system. The switches in the FTW module are activated by a system health signal controlled by a health monitor in the breakout system. The health monitor provides intelligent switch control based on alerts from a variety of control points. These control points include firmware, hardware, thermal sensors, subsystem operating systems, subsystem software applications, and appliance tamper logic in order to determine if the FTW module switches should be in an active or inactive state.

Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A breakout appliance in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. The breakout appliance includes multiple states that support manufacturing, testing, production, tamper detection and end of life, and the functions of the breakout appliance vary according to its state.

States for breakout appliance in a mobile data network

A method, apparatus, and computer instructions for transferring data from a master to a set of applications executing on a slave. Data is received from a master at a device driver in the slave. The data is parsed for an identifier by a virtual hub in the slave, wherein the identifier is associated with the data by the master. The data is sent to an application within the set of applications based on the identifier.
