Proximity-based services discovery privacy
First Claim
1. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a wireless communication device for protecting a user identity for device-to-device communication enabled user equipment, the instructions to configure the device to perform operations to:
- transmit a first temporary identification and first discovery information from a first user equipment (UE), the discovery information authorizing discovery of the first UE;
receive a request at the first UE from a second UE to join a device-to-device network with the first UE using a second temporary identification associated with the second UE;
resolve the first temporary address to provide a permanent ID associated with the first UE using previously stored resolution information associated with the permanent ID of the first UE and the first temporary ID; and
resolve the second temporary ID at the first UE to provide a permanent ID associated with the second UE using previously stored resolution information associated with the permanent ID of the second UE and the second temporary ID.

Abstract
This application discusses, among other things, apparatus and methods for providing device-to-device (D2D) discovery privacy. In an example, a method can include transmitting a first temporary identification and first discovery information from a first user equipment (UE), the discovery information authorizing discovery of the first UE; and receiving a request from a second UE to join a device-to-device network with the first UE using a second temporary identification associated with the second UE.

17. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a wireless communication device to configure the device to perform operations to:
-
transmit a first temporary identification and first discovery information from a first user equipment (UE), the discovery information authorizing discovery of the first UE; receive a request at the first UE from a second UE to join a device-to-device network with the first UE using a second temporary identification associated with the second UE; periodically replace the first temporary ID with a first replacement temporary ID; and wherein the instructions to periodically replace the first temporary ID include instructions to generate the first replacement ID at the first UE using a permutation algorithm simultaneously with generating the replacement ID at a network resource using the permutation algorithm. - View Dependent Claims (18, 19)
