Abstract: Measures are provided for management of RRC for D2D communication. Such measures include setting a connected state of RRC for device(s) of a pair of devices. For the devices(s), both a D2D communication service between the pair of devices and a core network communication service between the device(s) and a core network entity are active. The setting enables radio resource management for the device(s) for the D2D communication service and the core network communication service. Termination of the core network communication service is detected for the device(s). A connection towards the core network entity is reconfigured for disabling the core network communication service of the device(s). The connected state of RRC is maintained for the devices(s) of the pair of devices, for which the device(s) only the device-to-device communication service is active. The maintaining enables radio resource management for the device(s) for the D2D communication service.
