1. An apparatus to be employed in a user equipment (UE), the apparatus comprising:
- transmit circuitry to transmit, to a server of a wireless network, a proximity request message to enable discovery of a remote UE; and
receive circuitry to;
in response to the transmission of the proximity request message, a proximity response message that includes a temporary identifier assigned to the UE and a temporary identifier of the remote UE, wherein the temporary identifier assigned to the UE is different from a permanent identifier of the UE, and the temporary identifier of the remote UE is different from a permanent identifier of the remote UE; and
receive, from the remote UE over a direct wireless connection, a signal that includes the temporary identifier of the remote UE.

Abstract
In embodiments, apparatuses, methods, and storage media may be described for establishing a direct connection between two UEs. Each UE may be provisioned with a temporary identifier by a server of a wireless network of the UE. The UEs may then be configured to broadcast the temporary IDs in radio signals over radio resources that are separate from the radio resources of the network. The temporary IDs may not contain identifying information of the broadcasting UE that is interpretable without receiving further information from the network.

7. One or more non-transitory computer readable media comprising instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
-
transmit, to a server of a wireless network, a proximity request message for discovery of a remote UE; receive, from the server of the wireless network based on the proximity request message, a proximity response or proximity alert message that includes a temporary identifier assigned to the UE, wherein the temporary identifier is different than a permanent identifier of the UE; transmit, to an eNodeB (eNB) of the wireless network, a validation request including the temporary identifier of the UE; receive, in response to the validation request, a validation response including a radio resource; and transmit, in response to the validation response, a discovery signal on the radio resource, the discovery signal including the temporary identifier of the UE. - View Dependent Claims (8, 9, 10, 14)

11. A method comprising:
-
transmitting, from a server of a third generation partnership project (3GPP) network, an indication to a network node in the 3GPP network that a first user equipment (UE) in the 3GPP network is allowed to engage in direct discovery with a second UE in the 3GPP network; receiving, by the server, a proximity request from the first UE to engage in direct discovery with the second UE, the request including an application identifier of the second UE; assigning, by the server, a temporary identifier to the first UE in response to reception of the proximity request from the first UE that is different from a permanent identifier of the first UE; transmitting, by the server and based at least in part on the request from the first UE, a request to a second server in the 3GPP network, the request including the application identifier of the second UE and the temporary identifier of the first UE; receiving, by the server, a proximity response from the second server, the proximity response including a temporary identifier of the second UE that is different from a permanent identifier of the second UE; and transmitting, by the server, the proximity response to the first UE, the proximity response including the temporary identifier of the first UE and the temporary identifier of the second UE. - View Dependent Claims (12, 15)
