Abstract
A method of forming a secure group in ProSe communication includes requesting a service request to a ProSe server from a requesting device (21), the service request indicating a request to communicate with a receiving device (22) from the requesting device (21), performing verification on the requesting and receiving devices (21) and (22) by the ProSe server 24, sending a ProSe Service Result to the requesting and receiving devices (21) and (22) to inform to be allowed a group member, and starting a group security establishment of the group including the requesting and receiving devices (21) and (22)
Claims24
A communication system for Proximity Services (ProSe) Direct Discovery, comprising:
- a first UE (User Equipment) that supports the ProSe;
- a second UE that supports the Prose;
- a network that includes at least a ProSe Function and a ProSe application server;
- wherein the first UE sends a request for the Direct Discovery including a first information to the network,
- the network checks the first UE and the second UE and responds to the first UE;
- the first UE broadcasts a message to a second UE through a PC5 interface, and
- the second UE receives the message and verifies the message based on a second information provided from the network.
A Proximity services (ProSe) Direct Discovery method in a communication system including a first UE (User Equipment) that supports the ProSe, a second UE that supports the ProSe, and a network that includes at least a ProSe Function and a ProSe application server, comprising:
- sending, by the first UE, a request for the Direct Discovery including a first information to the network;
- checking, by the network, the first UE and the second UE and responding to the first UE;
- broadcasting, by the first UE, a message to a second UE through a PC5 interface;
- and
- receiving, by the second UE, the message and verifying the message based on a second information provided from the network.
A network including at least a Proximity services (ProSe) Function and a ProSe application server for Proximity services (ProSe) Direct Discovery, comprising:
- a receiver configured to receive a request for the Direct Discovery including a first information from a first UE (User Equipment) that supports the ProSe;
- a controller configured to check the first UE and a second UE and respond to the first UE;
- wherein the first UE broadcasts a message to a second UE that supports the ProSe through a PC5 interface, and
- the second UE receives the message and verifies the message based on a second information provided from the network.
A Proximity Services (ProSe) Direct Discovery method of a network including at least a ProSe Function and a ProSe application server, comprising:
- receiving a request for the Direct Discovery including a first information from a first UE (User Equipment) that supports the ProSe;
- and
- checking the first UE and a second UE and responding to the first UE;
- wherein the first UE broadcasts a message to a second UE that supports the ProSe through a PC5 interface, and
- the second UE receives the message and verifies the message based on a second information provided from the network.
A UE (Use Equipment) that supports Proximity Services (ProSe) for ProSe Direct Discovery, comprising:
- a transmitter configured to send a request for the Direct Discovery including a first information to a network including at least a ProSe Function and a ProSe application server, and broadcast a message to another UE that supports ProSe through a PC5 interface;
- and
- a receiver configured to receive a response from the network that checks the UE and the another UE;
- wherein the another UE receives the message and verifies the message based on a second information provided from the network.
A Proximity Services (ProSe) Direct Discovery method of a UE (Use Equipment) that supports the ProSe, comprising:
- sending a request for the Direct Discovery including a first information to a network including at least a ProSe Function and a ProSe application server, and broadcasting a message to another UE that supports ProSe through a PC5 interface;
- and
- receiving a response from the network which checks the UE and the another UE;
- wherein the another UE receives the message and verifies the message based on a second information provided from the network.
