Abstract: A system is disclosed for the coordinated grouping of devices for receipt of network layer group based services. A service layer system such as an SCS generates a request to generate a group of devices to receive network layer services. The request is received at a network layer system such as, for example, an MTC-IWF. Network layer systems such as, for example, an HSS, identifies a manner of communicating the requested service to identified devices and communicates with the devices to provision the devices so as to be included in the requested group. The network layer systems communicate an identifier to the service layer system which the service layer may subsequently use to request execution of the service by the identified group of devices.

Abstract: Embodiments of the invention provide novel solutions, including systems, methods and/or software, for handling calls in a dual-mode VoIP/cellular environment. Merely by way of example, some systems can be configured to determine whether to use a VoIP system or a cellular system to handle a particular call, and/or to transition a call from one network to the other network. Other systems can be configured to substitute a public number (which might be, for example, a VoIP number) for a private number (which might be, for example, a cellular number) when routing a call originating from a dual-mode phone on a cellular network. Further systems can be configured to allow a VoIP system to serve as an anchor for calls originated and/or delivered on a cellular system, for instance to facilitate a transition between cellular and VoIP service during a call.

Abstract: A method can be used for detecting a potential presence of an object by a reader capable of mutually communicating via a contactless communications protocol. An antenna of the reader transmits a magnetic field on a carrier signal having a sub-carrier modulated by a first data sequence. The modulated sub-carrier is non-interpretable by the object. The antenna of the reader receives a signal resulting from the transmission. The reader demodulates the sub-carrier of the resulting signal so as to extract a second data sequence from the resulting signal. The first data sequence and second data sequence are correlated and the potential presence or absence of the object is determined based upon the result of the correlating.
