A method and apparatus for mapping a virtual machine in a cloud infrastructure to a network port. The method includes: obtaining, by a smart monitoring device distinct from the virtual machine and a network appliance, a first location of the virtual machine in the cloud infrastructure; mapping, by the smart monitoring device, the first location of the virtual machine to a first source port in the network appliance and a first destination port in the network appliance; based on a determination that the virtual machine is not at the first location, obtaining, by the smart monitoring device, a second location of the virtual machine in the cloud infrastructure; and based on the determination that the virtual machine is not at the first location, mapping, by the smart monitoring device, the second location of the virtual machine to a second source port in the network appliance and a second destination port in the network appliance.

Roaming coverage evaluation is performed by receiving a roaming handover message including an error code, the roaming handover message identifies a serving cell and a touch point, verifying whether the touch point is accepting roaming handovers by retrieving roaming information from the touch point, retrieving a signal report from a terminal served by the serving cell in response to determining that the touch point is not accepting roaming handovers, determining a signal strength difference between a signal of the touch point and a signal of a cell neighboring the touch point, and mitigating coverage loss due to the touch point not accepting roaming handovers based on the signal strength difference.

In a method of operating a portable access node, a lease request is transmitted to lease a portion of a communication resource assigned to but not used by a local communication system, where the portable access node is located within a coverage area of the local communication system. Upon receiving a response granting the lease request, a communication service using the leased portion of the communication resource is provided.

A server of a mobile network operator (MNO) executes network control logic for unbundling vertically integrated software on specialized hardware equipment, referred to here as a host. For example, the server performs a handshake with the host, and establishes an encrypted channel. The server then negotiates with the host, and determines those interfaces that the host will expose to third party software. The server, based on a current need of the MNO for a network service, compares the negotiation results with contents of a smart library. If the smart library does not have a registered and suitable app for the network service, the server obtains metadata corresponding to the app from a software supplier. The server then, for example, tests the metadata on a mockup of the host, under the control of the server. The host eventually runs the app, providing the network service without requiring an entire software revision of the host.

Managing a software application

A messaging method includes causing a mobile device to be registered in a database by storing identification information associated with the mobile device in the database and storing network connectivity information indicative of whether the mobile device is connected to a wireless network in the database. The method also includes facilitating a message to be communicated to the mobile device from a messaging device remote from the mobile device by causing the identification information and the network connectivity information to be communicated to the messaging device.
