Abstract
A mobile communication system includes a central processing unit coupled to a memory storing instructions for executing a User Equipment (UE) implemented by a transceiver and a controller that supports Proximity Services (ProSe), and a ProSe Function that supports the ProSe and communicates with the UE via a PC3 interface. The UE sends a message for a discovery to the ProSe Function via the PC3. The ProSe Function directly sends security information to the UE via the PC3. The UE directly sends a protected message to another UE an a PC5 interface using a key based on the security information.
Claims11
A mobile communication system, comprising:
- a central processing unit coupled to a memory storing instructions for executing:
- a User Equipment (UE) implemented by a transceiver and a controller that supports Proximity Services (ProSe);
- and
- a ProSe Function that supports the ProSe and communicates with the UE via a PC3 interface,
- wherein the UE sends a message for a discovery to the ProSe Function via the PC3,
- wherein the ProSe Function directly sends security information to the UE via the PC3, and
- wherein the UE directly sends a protected message to another UE on a PC5 interface using a key based on the security information.
A Proximity Services (ProSe) Function in a mobile communication system that includes a central processing unit coupled to a memory storing instructions for executing a User Equipment (UE), implemented by a transceiver and a controller, which supports ProSe and a ProSe Application Server, the ProSe Function comprising:
- the controller configured to support the ProSe and to communicate with the UE via a PC3 interface;
- and
- the transceiver configured to directly send security information to the UE via the PC3,
- wherein the UE directly sends a protected message to another UE on a PC5 interface using a key based on the security information.
A User Equipment (UE) implemented by a transceiver and a controller in a mobile communication system that includes a central processing unit coupled to a memory storing instructions for executing a Proximity Services (ProSe) Function that supports the ProSe and communicates with the UE via a PC3 interface, the UE comprising:
- the controller configured to directly communicate with the ProSe Function via PC3 interface, and to support the ProSe;
- and
- the transceiver configured to send a message for a discovery to the ProSe Function, to directly receive security information from the ProSe Function, and to directly send a protected message to another UE on a PC5 interface using a key based on the information.
A method of a mobile communication system including a User Equipment (UE) that supports Proximity Services (ProSe), and a ProSe Function that supports the ProSe and communicates with the UE via a PC3 interface, the method comprising:
- sending, by the UE, a message for a discovery to the ProSe Function via the PC3;
- sending directly, by the ProSe Function, security information to the UE via the PC3;
- and
- sending directly, by the UE, a protected message to another UE on a PC5 interface using a key based on the security information.
A method of a Proximity Services (ProSe) Function in a mobile communication system that includes a User Equipment (UE) which supports ProSe, and a ProSe Application Server, the method comprising:
- supporting the ProSe;
- communicating with the UE via a PC3 interface;
- and
- sending directly security information to the UE via the PC3,
- wherein the UE directly sends a protected message to another UE on a PC5 interface using a key based on the security information.
A method of at User Equipment (UE) in a mobile communication system that includes a Proximity Services (ProSe) Function that supports the ProSe and communicates with the UE via a PC3 interface, and a ProSe application server that communicates with the ProSe function via a PC2 interface, the method comprising:
- communicating directly with the ProSe Function via PC3 interface;
- supporting the ProSe;
- sending a message for a discovery to the ProSe Function;
- receiving directly security information from the ProSe Function;
- and
- sending directly a protected message to another UE on a PC5 interface using a key based on the information.
