Abstract
A method for processing a security policy of a device may include a step for receiving, from another device, a first message including first information about a security policy of the other device. The first message may include a direct communication request message or a link modification request message. The method may further include the steps of: determining whether to accept or reject the first message on the basis of both the first information about the security policy of the other device and second information about the security policy of the device; and sending a second message on the basis of the determination.
Claims19
A security policy handling method performed by a User Equipment (UE), the method comprising:
- receiving, from an initiating UE, a first message for a PC5 unicast link between the initiating UE and the UE,
- wherein the first message includes a security policy of the initiating UE, and the first message is a direct communication request message or a link modification request message,
- determining whether to accept or reject the first message, based on both the security policy of the initiating UE and a security policy of the UE,
- wherein the security policy of the initiating UE relates to activating or deactivating a security for the PC5 unicast link, and
- wherein whether to accept or reject the first message is determined based on comparing the security policy of the initiating UE and a security policy of the UE;
- and
- transmitting a second message, based on the determination.
A User Equipment (UE) comprising:
- at least one processor;
- and
- at least one memory for storing instructions and operably electrically connectable with the at least one processor, wherein the instructions are executed based on execution by the at least one processors, to perform operations include:
- receiving, from an initiating UE, a first message for a PC5 unicast link between the initiating UE and the UE,
- wherein the first message includes a security policy of the initiating UE, and the first message is a direct communication request message or a link modification request message,
- determining whether to accept or reject the first message, based on both the security policy of the initiating UE and a security policy of the UE,
- wherein the security policy of the initiating UE relates to activating or deactivating a security for the PC5 unicast link, and
- wherein whether to accept or reject the first message is determined based on comparing the security policy of the initiating UE and a security policy of the UE;
- and
- transmitting a second message, based on the determination.
A security policy handling method performed by a initiating User Equipment (UE), the method comprising:
- transmitting, to a UE, a first message for a PC5 unicast link between the initiating UE and the UE,
- wherein the first message includes a security policy of the initiating UE, and the first message is a direct communication request message or a link modification request message;
- and
- receiving a second message from the UE,
- wherein the second message is transmitted by the UE, based on that the UE determines whether to accept or reject the first message, based on both the security policy of the initiating UE and a security policy of the UE, wherein the security policy of the initiating UE relates to activating or deactivating a security for the PC5 unicast link, and
- wherein whether to accept or reject the first message is determined based on comparing the security policy of the initiating UE and a security policy of the UE.
