Abstract: A communication system and method for supporting a plurality of vehicle-to-everything radio access technologies (V2X RATs) is provided. The communication system configured to support multiple V2X RATs transmits, using a first V2X RAT, an indication of its availability to support an interworking function between the plurality of V2X RATs. The communication system receives an instruction to provide the interworking function between different V2X RATs. The interworking function may be incorporated in a vehicle that is joined to a platoon configured to use a first V2X RAT, and provide the interworking function between the first and a second V2X RAT. The interworking function may be used to add further vehicles to the platoon that communicate using only the second V2X RAT.

Abstract: A method implemented by a network node is disclosed. The method includes: obtaining registration state information associated with a user equipment (UE) from a first core network node, the registration state information indicating at least one of fourth-generation (4G) UE single radio voice call continuity (SRVCC) capability or fifth-generation (5G) UE SRVCC capability for the UE, wherein the UE is registered with a first IMS network that includes the network node using a session initiation protocol (SIP) via an access network supported by a second core network; and providing, to a second IMS network node, an indication of a single UE SRVCC capability for the UE.

Abstract: A method for transferring data using optimized short message transport includes receiving at a first network node an attach request message. The attach request message includes short-message data. The first network node receives from a second network node a short-message data response message. The short-message data response message includes at least one of an address for a short message service center, an indication that indicates no mobile-terminated message is pending for the UE, or a short-message entity destination address.

Abstract: A method, computer program product, user equipment (UE) and packet data network gateway (P-GW) are provided for activating “Data Off” services using protocol configuration options (PCO). The UE sends a first indication to a first network node as part of the PCO. The first indication includes a Data Off indication indicating whether a “Data Off” service is activated. The first network node may be a P-GW. If the Data Off indication indicates that the “Data Off” service is deactivated, the UE receives downlink data from the first network node. If the Data Off indication indicates that the “Data Off” service is activated, the UE either receives no downlink data from the first network node or receives an error message from the first network node.
