Abstract: In cellular or other wireless networks, relay communication devices can be introduced to support an indirect network connection for remote communication devices in out-of-coverage (OoC) areas to thereby extend access device coverage and increase available data capacity for communication devices that may not be in optimal coverage of an access device. For directly connected communication devices, mechanisms for bit rate recommendation, bit rate query and desired bit rate indication are defined. However, these existing mechanisms do not work for communication devices indirectly connected via a relay communication device. It is therefore proposed to determine a new data rate recommendation and/or limit for one or more downstream communication devices at least partly based on an identity of a logical channel indicated in a received recommendation and/or limit.

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).
