  • Patent number: 9838258
    Abstract: Utilizing a network service interface function within a machine-to-machine common service layer is presented herein. A method can comprise determining network configuration information for network devices coupled to a set of distributed remote devices; receiving a device request directed to a remote device of the set of distributed remote devices; determining, based on the network configuration information, a network interface for facilitating performance of the device request; and sending, via the network interface, command information corresponding to the device request directed to the remote device. In an example, in response to determining that a traffic load of a communication channel associated with the remote device satisfies a defined condition with respect to an increased loading of such channel, the method can comprise sending a message to request delay of the device request if the device request has been determined to be a non-priority request.

  • Patent number: 8897285
    Abstract: System(s), device(s), and method(s) are provided to characterize a temporary identifier for user equipment (UE) in telecommunication procedure(s) in a wireless communication network. Based on radio technology of at least one serving node that enables at least part of the telecommunication procedure(s), the UE generates a TI and a classifier that discloses the type of the TI. The classifier enables distinguishing a TI value in a first radio technology from a TI value in a second radio technology. In addition the classifier enables a serving node that receives the classifier to identify a logic address of a disparate serving node without restriction in backwards compatibility amongst radio protocols utilized by the wireless communication network.

  • Patent number: 8175236
    Abstract: Providing for inter-working between SMS network architectures and IMS network architectures in a mobile environment is described herein. By way of example, a next generation (NG) short message service center (SMSC) is provided that can receive SMS messages in mobile application protocol (MAP) and convert such messages to IMS protocol. In addition, the NG SMSC can also receive IMS data and convert the IMS data to an SMS MAP message. The NG SMSC can reference an IMS or an SMS location registry to determine a location of the target device, and convert from IMS to SMS MAP, and vice versa, as suitable. Accordingly, the NG SMSC can provide an efficient interface between legacy SMS and NG IMS network components while preserving legacy protocols associated with such networks.
