Abstract: An intruder detection method is provided, comprising a security server sending a verification prompt to a device in a controlled-access area, based on an entry indication of an entrant into the controlled-access area, with the verification prompt indicating the entrant should perform a predefined verification action, the security server receiving entrant behavior information, the security server comparing the entrant behavior information to a behavior model of a set of authorized persons associated with the controlled-access area, with the behavior model including the verification prompt, and the security server generating an intruder indication if the entrant behavior information does not match a behavior sequence included in the behavior model.

Abstract: A location method in a communication network is provided. The method comprises a user equipment (UE) generating a geofence distance between a current UE location and a geofence, the UE comparing the geofence distance to a range threshold R, and the UE using a more accurate location determination when the geofence distance is less than the range threshold R.

Abstract: Various disclosed embodiments include methods and systems for provisioning traversal using relays around network address translation (TURN) credentials and servers for network address translation/firewall (NAT/FW) traversal via a Voice-over-Internet-protocol/Web Real-Time Communication (VoIP/WebRTC) signaling channel. The method comprises receiving, at a signaling gateway, a signaling message from a first electronic device (ED) when the first electronic device registers with the signaling gateway or sends other signaling messages for requesting a TURN credential. The signaling message comprises one or more signaling message parameters. The signaling message further comprises a request that the signaling gateway generate a TURN credential for the first electronic device, the TURN credential associated with the one or more signaling message parameters. The method comprises sending, from the signaling gateway, the TURN credential to the first electronic device.

Abstract: A method implemented by a network element (NE), comprising receiving a classification message comprising a classification rule for identifying a service function chain (SFC) in a network, wherein the SFC comprises an ordered set of service functions (SFs) that provides services to an application, and a dynamic application-specific contextual data associated with an operation of the application, receiving a first of a plurality of application data packets, determining that the first of the application data packets matches the classification rule, generating a first SFC packet by adding the dynamic application-specific contextual data to the first of the application data packets according to the classification rule to enable communication of the dynamic application-specific contextual data to at least one of the SFs in the SFC, and sending the first SFC packet towards a next NE according to an SF path in the network associated with the SFC.
