Effective proximity service discovery resource reporting and allocation. Embodiments of the invention relate to a method for enhancing proximity service (ProSe) device to device discovery resource allocation, the method comprising: allocating, by a network processing device, network resources to a plurality of user devices including at least one user device in a connected mode and at least one user device in an idle mode, the allocating comprising: restricting network resources allocated to the user device in the idle mode for proximity service discovery compared to the network resources allocated to the user device in the connected mode for proximity service discovery, such that the network resources maintain reliable discovery services for the user device in the connected mode as well as provide acceptable discovery services for the user device in the idle mode.
