Benefits of technology
The invention provides a network apparatus and computer program for enhancing the discovery between user devices through the use of proximity services (ProSe). By restricting network resources allocated to idle user devices, the apparatus ensures reliable discovery services for connected user devices and provides acceptable discovery services for idle user devices. Additionally, the invention includes a method for allocating network resources to connected and idle user devices, as well as an apparatus for performing this allocation. Ultimately, the invention improves the efficiency and effectiveness of ProSe device-to-device discovery.
Problems solved by technology
This may affect the stability of the discovery system performance as the UE in the idle mode will use network resources for the discovery session.
In some cases, use of network resources by the UE in the idle mode may hinder discovery sessions of the UE in a connection mode, and in some cases, the discovery session of the UE in the idle mode may fail due to insufficient resources or collision with another discovery session.

Embodiment Construction
[0041]Embodiments of the present invention may now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure may satisfy applicable legal requirements. Like numbers refer to like elements throughout.
[0042]In expected implementations, the network, such as network eNB 120 will assign or allocate (or provide) common resources for all D2D users (UEs in the connected mode (also referred to as connected UEs) and UEs in the idle mode (also referred to as idle UEs)) for use in discovery. Such allocation may provide resource and signaling efficiency. In a case where only UEs in the connected mode are allowed to initiate discovery, the network would be able to make an accurate estimation on the need for re...

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.
Description
FIELD OF THE INVENTION[0001]This disclosure relates to proximity service discovery resource status report and allocation.BACKGROUND OF THE RELATED ART[0002]The Third Generation Partnership Project (3GPP) radio access network (RAN) collaboration has addressed device to device (D2D) proximity services (ProSe) or proximity based applications. A core component of proximity services is discovery of user equipment (UE), also referred to as user devices, apparatuses and the like. ProSe discovery may involve two or more UEs in proximity to one another. Identified use cases for proximity-based services include public safety and non-public safety scenarios.[0003]In some cases, a UE in an idle (non-network-connected) mode may voluntarily initiate a ProSe D2D discovery session. This may affect the stability of the discovery system performance as the UE in the idle mode will use network resources for the discovery session. In some cases, use of network resources by the UE in the idle mode may hi...
