1. A method comprising:
- configuring common resources for supporting direct communication between terminals across a predefined registration area for direct communication comprising one or more cells of a cellular system of an evolved UNITS terrestrial radio access network, andcontrolling an allocation of common resources for enabling direct communication between terminals across the predefined registration area,said controlling comprising;
determining and assigning the allocation of common resources and the configuration thereof to a terminal being registered to the predefined registration area with a temporary identifier allocated by the cellular system identifying the terminal at least in cellular idle state to the cellular system, andwherein said enabling comprises at least one of;
using the assigned resources for advertising the presence of the terminal for direct communication to terminals in the registration area, andusing the assigned resources for detecting the terminal as communication partner for direct communication by terminals in the registration area.

Abstract
Resource allocation for direct terminal-to-terminal communication in a cellular system. There are provided measures for resource allocation for direct terminal-to-terminal communication in a cellular system, said measures exemplarily including configuration of common resources for supporting direct communication between terminals across a predefined registration area including one or more cells of a cellular system, and control of an allocation of common resources for enabling direct communication between terminals across the predefined registration area. Said measures may exemplarily be applied for establishing terminal-to-terminal communication in LTE or LTE-Advanced cellular networks.
