7 .- 21 . (canceled)
22 . A multi-path transmission method, comprising: sending, by a policy control function (PCF) network element or a session management function (SMF) network element, a security policy for a first service, wherein the security policy for the first service is configured for multi-path transmission of the first service, the multi-path transmission of the first service comprises a first path for communication between a first UE and a base station, and a second path for communication between the first UE and the base station via a second UE.
23 . The method according to claim 22 , wherein the security policy comprises any one of: required; or not needed.
24 . The method according to claim 22 , wherein the first path is a Uu link; the second path comprises a PC5 link between the first UE and the second UE and a Uu link between the second UE and the base station.
25 . The method according to claim 22 , wherein sending the security policy comprises: configuring, by the PCF network element, the security policy for the first service for the first UE and the second UE, respectively, wherein the security policy for the first service configured by the PCF network element for the first UE and the second UE is the same as a security policy for the first service configured by an SMF network element for the base station.
26 . The method according to claim 22 , wherein the security policy comprises at least one of: a UP integrity protection and/or confidentiality protection policy for a PC5 link; a UP integrity protection and/or confidentiality protection policy for a Uu link; a signaling integrity protection and/or confidentiality protection policy for a PC5 link; or a signaling integrity protection and/or confidentiality protection policy for a Uu link.
27 .- 31 . (canceled)
32 . A communication device, comprising a processor and a memory having a computer program stored thereon, wherein the processor is configure to: acquire a security policy for a first service, wherein the security policy for the first service is configured for multi-path transmission of the first service, the multi-path transmission of the first service comprises a first path for communication between the first UE and a base station, and a second path for communication between the first UE and the base station via a second UE; and perform the multi-path transmission of the first service according to the security policy for the first service.
33 . (canceled)
34 . (canceled)
35 . A communication device comprising a processor and a memory having a computer program stored thereon, wherein the processor is configure to perform the method according to claim 22 .
