The method includes a communications device receiving a PWS message over a first communication technology. The method also includes the communications device relaying all or part of the PWS message over a second communication technology, wherein the second communication technology is different than the first communication technology. ## Claims ### Claim 1 A method for relaying Public Warning System (PWS) messages, the method comprising: receiving, at a communications device, a PWS message over a first communication technology; and transmitting, by the communications device, a first output message comprising all or part of the PWS message over a second communication technology, the second communication technology being different from the first communication technology. ### Claim 2 (depends on 1) The method of claim 1, wherein the first communication technology comprises a radio access technology (RAT) and wherein the second communication technology comprises a short-range communication technology. ### Claim 3 (depends on 2) The method of claim 2, wherein the PWS message is received over the RAT from a network node in a telecommunications network, the telecommunications network comprising a Global System for Mobile communications (GSM)/Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GERAN), a Universal Mobile Telecommunications System (UMTS), Universal Terrestrial Radio Access Network (UTRAN), an Evolved UTRAN (E-UTRAN), or a new generation Radio Access Network. ### Claim 4 (depends on 2) The method of claim 2, wherein transmitting comprises the communications device relaying all or part of the PWS message over the short-range communication technology to a remote user equipment (UE) via a Device to Device (D2D) interface. ### Claim 5 (depends on 4) The method of claim 4, further comprising the communications device formatting the first output message prior to relaying all or part of the PWS message to the remote UE, wherein the first output message is formatted based on at least one of: the first communication technology over which the PWS message was received by the communications device; or a message identifier within the PWS message. ### Claim 6 (depends on 4) The method of claim 4, further comprising: receiving, by the communications device, the PWS message over the RAT; determining, by the communications device, whether a secondary PWS message related to the PWS message is available; and responsive to determining that the secondary PWS message is available, relaying, by the communications device, the secondary PWS message to the remote UE over the short-range communication technology via the D2D interface, wherein the D2D interface comprises a PC5 interface. ### Claim 7 (depends on 2) The method of claim 2, wherein the communications device relays, over the short-range communication technology, the PWS message as a Decentralized Environmental Notification Message (DENM) to a remote user equipment (UE), and wherein the DENM is based on an Intelligent Transport Systems (ITS) standard. ### Claim 8 A communications device comprising: a memory containing instructions; and a processor coupled to the memory and configured to execute the instructions such that the communications device: receives a Public Warning System (PWS) message over a first communication technology; and transmits a PWS output message comprising all or part of the PWS message over a second communication technology, the second communication technology being different from the first communication technology. ### Claim 9 (depends on 8) The communications device of claim 8, wherein the first communication technology comprises a radio access technology (RAT) and wherein the second communication technology comprises a short-range communication technology. ### Claim 10 (depends on 9) The communications device of claim 9, wherein the PWS message is received over the RAT from a network node in a telecommunications network, the telecommunications network comprising a Global System for Mobile communications (GSM)/Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GERAN), a Universal Mobile Telecommunications System (UMTS), Universal Terrestrial RAN (UTRAN), an Evolved UTRAN (E-UTRAN), or a new generation Radio Access Network. ### Claim 11 (depends on 9) The communications device of claim 9, wherein the communications device relays all or part of the PWS message over the short-range communication technology to a remote user equipment (UE) via a Device to Device (D2D) interface. ### Claim 12 (depends on 11) The communications device of claim 11, wherein the communications device formats the PWS output message prior to relaying all or part of the PWS message to the remote UE via the D2D interface, wherein the D2D interface comprises a PC5 interface, wherein the PWS output message is formatted based on at least one of: the first communication technology over which the PWS message was received by the communications device; or a message identifier within the PWS message. ### Claim 13 (depends on 9) The communications device of claim 9, wherein executing the instructions is such that the communications device: receives the PWS message over the RAT; determines whether a secondary PWS message related to the PWS message is available; and responsive to determining that the secondary PWS message is available, relays the secondary PWS message to a remote user equipment (UE) over the short-range communication technology. ### Claim 14 A computer-readable medium containing instructions executable by a processor such that when executed, cause the processor to implement a method on a communications device, the method comprising: receiving, at the communications device, a Public Warning System (PWS) message over a first communication technology; and transmitting, by the communications device, a PWS output message comprising all or part the PWS message over a second communication technology, the second communication technology being different from the first communication technology. ### Claim 15 (depends on 14) The computer-readable medium of claim 14, wherein the first communication technology comprises a radio access technology (RAT) and wherein the second communication technology comprises a short-range communication technology. ### Claim 16 (depends on 15) The computer-readable medium of claim 15, wherein the PWS message is received over the RAT from a network node in a telecommunications network, the telecommunications network comprising a Global System for Mobile communications (GSM)/Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GERAN), a Universal Mobile Telecommunications System (UMTS), Universal Terrestrial Radio Access Network (UTRAN), an Evolved UTRAN (E-UTRAN), or a new generation Radio Access Network. ### Claim 17 (depends on 15) The computer-readable medium of claim 15, wherein the communications device relays all or part of the PWS message over the short-range communication technology to a remote user equipment (UE) via a Device to Device (D2D) interface. ### Claim 18 (depends on 17) The computer-readable medium of claim 17, the method further comprising the communications device formatting the PWS output message prior to relaying all or part of the PWS message to the remote UE via the D2D interface, wherein the D2D interface comprises a PC5 interface, wherein the PWS output message is formatted based on at least one of: the first communication technology over which the PWS message was received by the communications device; or a message identifier within the PWS message. ### Claim 19 (depends on 17) The computer-readable medium of claim 17, the method further comprising: receiving, by the communications device, the PWS message over the GERAN or RAT; determining, by the communications device, whether a secondary PWS message related to the PWS message is available; and responsive to determining that the secondary PWS message is available, relaying, by the communications device, the secondary PWS message to the remote UE over the short-range communication technology. ### Claim 20 (depends on 15) The computer-readable medium of claim 15, wherein the communications device relays, over the short-range communication technology, the PWS message as a Decentralized Environmental Notification Message (DENM) to a remote user equipment (UE), and wherein the DENM is based on an Intelligent Transport Systems (ITS) standard.
