Apparatus and method for controlling the establishment of a network connection to a mobile relay; communicating with the moving relay connected to a donor network; controlling the activation, reactivation and setup of the connection
摘要:
A network entity interlaces with at least one other apparatus. The network entity receives a plurality of reports from respective terminals, each report being indicative of a detection of at least one particular apparatus of a specific type by the respective terminal, and analyzes the plurality of reports. The network entity determines that terminals, the reporis of which are indicative of the samo particular apparatus of the specific type, are in proximity to each other, and causes transmission of a corresponding proximity indication to each terminal for which a proximity to one or more other terminals was determined. Similarly, corresponding proximity discovery agent entities, i.e. apparatus of the specie type, corresponding terminal apparatuses and related methods as well as computer program products are envisaged.
摘要:
A method includes providing a broadband public safety network PSN that includes at least a first MS1 and a second MS2 mobile device and a first coverage area; and providing a broadband mobile communication network CN including a second coverage area 104. The method includes detecting the MS1 and MS2 mobile devices are residing out of the first coverage area and residing in the second coverage area 104. Then the MS1 and MS2 mobile devices are starting to operate in a Device to Device mode 204. The method further includes defining a group including the MS1 and MS2 mobile devices that are communicating in the Device to Device mode. The method includes determining, by using a selection mechanism including one or several timers, which of the MS1 and MS2 mobile devices acts as a controlling mobile device for the group 202.

This document discloses transmission of a radio link failure control message in a situation where a control plane connection is established directly between a first access point of a cellular communication system and a terminal device of the cellular communication system and, additionally, a user plane connection is established between the first access point and the terminal device through a second access point. The radio link failure control message is transferred over the user plane connection during the radio link failure or proactively in an attempt to prevent the radio link failure.

There is provided a method, comprising: establishing, by a first network node, a communication connection to at least one advertising device located in a geographically limited service area; establishing a communication connection to at least one advertisement-receiving device; generating at least one security key for encrypting and decrypting at least part of the data which is to be transmitted in D2D communication links, wherein each security key is valid for a predetermined validity period, and common to those at least one advertising device and at least one advertisement-receiving device within the service area which fulfill predetermined criteria; causing transmission of information indicating the generated at least one security key to those at least one advertising device which fulfill the predetermined criteria; and causing transmission of information indicating at least one of the generated at least one security key to those at least one advertisement-receiving device which fulfill the predetermined criteria.
摘要:
The invention relates to an apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: configure an apparatus capable to device-to-device communications to operate as a local proximity services advertising agent device, and/or configure a proximity services advertising source device to operate as a local proximity services advertising agent device or associate the proximity services advertising source device with an existing local proximity services advertising agent device, and provide commercial information to the local proximity services advertising agent device for local delivery.
摘要:
It is provided an apparatus, including base station means to provide a base station functionality using component carriers; neighbor detecting means to detect a neighboring base station; informing means to inform a coordinating device about the neighboring base station; willingness setting means to set a willingness to perform self-tuning based on a respective long-term priority for each component carrier, wherein the long-term priorities are received from the coordinating device, and the willingness is only set if the long-term priorities are not in contradiction to an actual requirement, willingness providing means to provide an indication of the willingness to the coordinating device; and self-tuning means to perform self-tuning if an agreement statement is received from the coordinating device, wherein, as a result of the self-tuning, a usage of each component carrier by the base station means is based on the received long-term information and the actual requirement.
