Abstract
A technology for a user equipment (UE) that is operable to communicate in a device to device (D2D) network. A proximity detection request can be communicated to an evolved packet core (EPC). The proximity detection request can include a window parameter, an identification information of a second UE, and a proximity detection signal indicating whether the proximity detection request is for proximity detection of the second UE or for establishing a D2D connection with the second UE. A proximity alert message can be received from the EPC at the window parameter.
Claims24
A user equipment (UE) operable to communicate in a peer to peer (P2P) network, the UE having one or more processors configured to:
- communicate, to a proximity services (ProSe) server in an Evolved Packet Core (EPC), a proximity detection request, wherein the proximity detection request includes:
- a time period window parameter;
- an identification information of a second UE, and
- a proximity detection signal indicating whether the proximity detection request is for proximity detection of the second UE or for establishing a P2P connection with the second UE;
- and
- identifying that a proximity alert message, received from the ProSe server, is received within a time period of the time period window parameter.
A non-transitory machine readable storage medium having instructions embodied thereon, the instructions being executed by one or more processors to perform the following operations:
- generating, at a first user equipment (UE), a proximity detection request to be communicated to a proximity services (ProSe) server, wherein the proximity detection request includes:
- a time period window parameter;
- an identification information of a second UE, and
- a proximity detection signal indicating whether the proximity detection request is for proximity detection of the second UE or for establishing a P2P connection with the second UE;
- and
- identifying that a proximity alert message, received from the ProSe server, is received within a time period of the time period window parameter.
A method for communicating in a peer to peer (P2P) network, the method comprising:
- communicating, from a user equipment (UE) to a proximity services (ProSe) server in an Evolved Packet Core (EPC), a proximity detection request, wherein the proximity detection request includes:
- a time period window parameter;
- an identification information of a second UE, and
- a proximity detection signal indicating whether the proximity detection request is for proximity detection of the second UE or for establishing a P2P connection with the second UE;
- and
- receiving, at the UE from the ProSe server, a proximity alert message at a selected time based on the time period window parameter.
A proximity services (ProSe) server operable to communicate in a peer to peer (P2P) network, the ProSe server having one or more processors configured to:
- receive, from a user equipment (UE), a proximity detection request, wherein the proximity detection request includes:
- a time period window parameter;
- an identification information of a second UE, and
- a proximity detection signal indicating whether the proximity detection request is for proximity detection of the second UE or for establishing a P2P connection with the second UE;
- and
- send a proximity alert message to the UE within a time period based on the time period window parameter.
