    Abstract: An apparatus including: at least one processor, and at least one memory for storing instructions to be executed by the processor, wherein the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least: request for using a part of a spectrum of a second communication network on the basis of a spectrum cooperation relationship between a first communication network and the second communication network, provide a service coordination information related to the request for using a part of the spectrum, the service coordination information indicating measures based on roaming mechanism offered by the first communication network allowing the second communication network to obtain compensation in the form of communication resources or traffic for using a part of the spectrum of the second communication network by the first communication network, and receive and process a response to the request for using a part of the spectrum of the second communication network and a service coordination response informing about accepted measures of those being offered in the service coordination information.

    Abstract: The invention relates to device-to-device (D2D) communications an in particular to location registration of a D2D User Equipment (UE) being in idle mode. A D2D capable UE (D2D cluster head) is [1] configured to communicate with a communication network, is [2] able to establish D2D communication with another D2D capable UE, receives [3] from the communication system a configuration so as to send location update related messaging on behalf of UEs with which D2D communications has been established, obtains [4] information of a change of status of a UE regarding a D2D communication or a change of cell of a UE and in response to the information, causes [5] the sending of a message to the communication network, the message comprising a location update request regarding the UE.

    Abstract: There is provided a method, comprising: configuring, by a network node controlling a macro cell of a cellular communication system, at least one handover trigger related signalling configuration for at least one terminal device of the cellular communication system; receiving, by the network node controlling the macro cell, as a result of said signalling configuration, an uplink message broadcasted by the at least one terminal device via a local area access node; recognizing the local area access node as an edge node located at an edge of a coverage area of the macro cell; and initiating a handover of the terminal device between the macro cell and a neighbouring macro cell.
