A method performed by a V2X user equipment, UE, for service discovery from a V2X application server, AS, the method comprising: sending, to an address of a configuration management server of the V2X AS, a first discovery request for further address information, associated with the V2X AS, wherein the further address information facilitates discovery of V2X services available via unicast communication between the V2X UE and a radio access network, RAN; receiving, the configuration management server of the V2X AS, a first discovery response comprising the requested further address information; sending a second discovery request, to the V2X AS, for V2X services available via the unicast communication, wherein: the second discovery request is sent to the further address information; and receiving, from the V2X AS, a further message in response to the second discovery request comprising: identification of one or more V2X services available via unicast communication between the V2X UE and the RAN; and information mapping the identified services to the further address information received in the first discovery response; and wherein the second discovery request is sent by, and the further message is received by, a V2X application enabler, VAE, client included by the V2X UE. sending, to an address of a configuration management server of the V2X AS, a first discovery request for further address information, associated with the V2X AS, wherein the further address information facilitates discovery of V2X services available via unicast communication between the V2X UE and a radio access network, RAN; receiving, the configuration management server of the V2X AS, a first discovery response comprising the requested further address information; sending a second discovery request, to the V2X AS, for V2X services available via the unicast communication, wherein: the second discovery request is sent to the further address information; and receiving, from the V2X AS, a further message in response to the second discovery request comprising: identification of one or more V2X services available via unicast communication between the V2X UE and the RAN; and information mapping the identified services to the further address information received in the first discovery response; and wherein the second discovery request is sent by, and the further message is received by, a V2X application enabler, VAE, client included by the V2X UE. the second discovery request is sent to the further address information; and receiving, from the V2X AS, a further message in response to the second discovery request comprising: identification of one or more V2X services available via unicast communication between the V2X UE and the RAN; and information mapping the identified services to the further address information received in the first discovery response; and wherein the second discovery request is sent by, and the further message is received by, a V2X application enabler, VAE, client included by the V2X UE. identification of one or more V2X services available via unicast communication between the V2X UE and the RAN; and information mapping the identified services to the further address information received in the first discovery response; and wherein the second discovery request is sent by, and the further message is received by, a V2X application enabler, VAE, client included by the V2X UE.
