Abstract: A location of a client in a private network where the client has a plurality of interfaces for using a plurality of internet gateways for coupling with the public internet can be determined by sending, from the client, a plurality of STUN BINDING requests to a STUN server connected to the public internet that each exit through an individual internet gateway, receiving, at the client, a plurality of STUN BINDING responses from the STUN server that each include public IP address mapped to the internet gateway through which the STUN BINDING request has exited the private network, sending, from the client, a plurality of location requests that each include a mapped public IP address and the corresponding private IP address, to a location server for looking up location data for the respective private IP addresses so the client can receive location data relating to the public IP addresses.

Abstract: A method for requesting connection in a blue-green deployment which is switched over from a first server (blue) to which at least two clients are connected to a second server (green). The method can include determining, upon receipt of the maintenance notification or detection of a connection failure, an activity score at each one of the at least two clients; and, upon switchover to the second server or detection of the connection failure, transmitting, together with a respective reconnection request, the respective activity score from each one of the at least two clients to the second server for the second server to evaluate a prioritization of the reconnection request based on the activity score. Embodiments of a communication system, server system, and clients (e.g. user devices) can utilize embodiments of the method.

Abstract: A system, a method and a device are each configured for dynamic assignment of survivability services to communication devices (such as, e.g. tablets, smart phones, mobile phones, laptops or other types of mobile communication devices) based on the device's current location and network context. Survivability services provide session and service continuity in case a centralized or cloud based session management service that may be hosted by one or more remote computer devices, such as for example servers, is not reachable due to network failure or service failure.
