Abstract: A first responder network is a network that is used by first responders for communicating between devices typically used by first responding officers. An MCI describes an incident in which emergency medical services are overwhelmed by the number and severity of casualties. A wireless communication system for first responder networks is proposed that can securely register (onboard) a variety of wireless devices to ensure a quicker response time in the MCI area. Existing wireless devices belonging to both triage officers and casualties in the MCI area can automatically be registered to a first responder network to enhance coverage in the MCI area. Expansion of a wireless infrastructure of the first responder network can be enabled by securely registering alien central nodes (e.g., base stations) on an on-demand basis.

Abstract: The present invention relates to a system that limits resources (e.g. reduces energy consumption and/or peak-to average power ratio) of a wireless communication device by limiting communication resources for the communication device from a network function of the cellular core network.

Abstract: The present invention relates to a system (100) for operating a user device (110) with personalized identity module profiles in which identity module profiles are automatically downloaded from a subscription manager (130) onto a user device (110) upon identification of the user (120) of the user device (110), in a secure manner. The system (100) especially comprises a service system (140) for identifying the user corresponding to the derived user identity, and a subscription manager (130) for preparing personalized identity module profiles requested by the service system (140) and sending the prepared personalized identity module profiles to the user device (110).
