A system may include a first network device. The first network device may include a first processor configured to: obtain a copy of a first message sent from an application on a User Equipment device (UE); construct a signature based on the copy of the first message; and send a second message including the signature to a second network device. The second message may request the second network device to either train a classification model or to provide a device type of the UE or an application type of the application to the first network device.

This application discloses a communication method and apparatus, to improve transmission efficiency of a control plane message of a terminal according to a control and provisioning of wireless access points protocol. In this application, a control request message of a terminal may be transmitted between a first communication apparatus and a second communication apparatus through a target channel. Because the target channel supports concurrency of a plurality of messages, transmission efficiency of the control request message of the terminal can be improved.

A mobile edge computing (MEC) service area can utilized packet header source and/or destination internet protocol data and session initiation protocol source and/or destination internet protocol data to map internet protocol addresses associated with mobile devices. The MEC can comprise a translation component that translates service provider internet protocol addresses such that they are perceived as enterprise premises internet protocol addresses. Conversely, the translation component can translate enterprise premises internet protocol addresses such that they are perceived as service provider internet protocol addresses.

Secure architectures and methods for improving the security of mobile devices are disclosed. Also disclosed are apparatuses and methods to detect and mitigate fraud in device-assisted services implementations.

Apparatus and methods for interworking a user device in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given user device (e.g., a mobile 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs), such as a macro network and micro network. In one implementation, the UE contains multiple SIM cards to enable connection to different networks simultaneously. Accordingly, the UE can roam between two different networks seamlessly, regardless of whether the operators of each are independent or the same operator. Enhanced network capability as described herein advantageously allows for interworking between the macro and micro (e.g., small-cell) layers of the system without complicated network configuration requirements between the two operating networks as required under the prior art.

A method, a wireless device and a session management node for IP version selection for a PDU session requested to be established by a WCD, that supports PDU sessions of both IPv4 and IPv6 and that is configured to operatively communicate via a RAN with a SM node in a core network 101, the method being performed by the WCD comprises: sending S110 a first PDU session request message towards the SM node requesting establishment of a first PDU session, which request message comprises IP-version information indicating that the IP version of the requested first PDU session should be any one of IPv4 or IPv6; and receiving S130, S140, in response to sending the first PDU session request message, a first response message, which first response message comprises WCD information indicating the IP-version (i.e. IPv4 or IPv6) that has been selected for the requested first PDU session.

An automatic train communications system includes a plurality of electronic train devices and a multi-channel communications network, wherein each electronic train device comprises a radio module configured to support a plurality of communications protocols and a plurality of frequency bands, and select a communications protocol and/or a frequency band from the plurality of communications protocols and frequency bands based on at least one performance criterium to reliably communicate with one or more electronic train devices via the multi-channel communications network.
