The server is configured to exchange with the cellular network information relating to at least one preconfigured qualifier assigned to the user equipment and assigned to the central server. The server receives a payload item from the cellular network transmitted by the user equipment to said cellular network by means of an authentication failure message for authenticating a user equipment at a cellular network during an attach comprising the payload item, instead of receiving a SMS or establishing an IP connection with the user equipment. The payload item can result from a latest measurement data of user equipment regularly transmitting data to said central server and/or a sensor connectively coupled to the user equipment when operating as an Internet of Things (IoT) smart-metering device. ## Claims ### Claim 1 A Central server for communicating with a user equipment through at least one cellular network, being communicatively coupled with said at least one cellular network, said central server being configured to exchange with said at least one cellular network information relating to at least one preconfigured qualifier assigned to at least one user equipment being assigned to the central server, and to receive a payload item from said cellular network transmitted by said user equipment to said cellular network by means of an authentication failure message for authenticating a user equipment at a cellular network during an attach process, wherein the authentication failure message comprises the payload item; wherein said payload item is the result of a measurement of a sensor connectively coupled to the user equipment when operating as an Internet of Things (IoT) smart-metering device. ### Claim 2 (depends on 1) The server of claim 1, wherein said payload item results from a latest measurement data of said user equipment operating as an Internet of Things (IoT) device regularly transmitting data to said central server. ### Claim 3 (depends on 2) The server of claim 2, wherein said payload item is the result of a measurement of consumed electricity of the last 24 hours. ### Claim 4 (depends on 1) The server of claim 1, wherein the attach process is started by the user equipment with an attach request message and synchronized to a base station to receive the attach request message, wherein a parameter of the attach request message is a preconfigured qualifier indicative of a subscription of the user equipment. ### Claim 5 (depends on 4) The server of claim 4, wherein the preconfigured qualifier is a permanent identifier either an IMSI or MSISDN. ### Claim 6 (depends on 4) The server of claim 4, wherein said communicating is managed by a Home Subscriber Server (HSS) assigned to check a status of subscription of camping base stations. ### Claim 7 (depends on 1) The Central server according to claim 1, further configured in response to receiving said payload item, to submit a response data item to the cellular network for submitting to the user equipment by means of a second authentication request message. ### Claim 8 (depends on 1) The Central server according to claim 1, further configured to store data relating to at least one preferred visited cellular network, and to provide at least one set of data relating to said preferred visited cellular networks to said communicatively coupled cellular network. ### Claim 9 (depends on 1) The Central server according to claim 1, provides for subscriptions of smart meter services to said user equipment. ### Claim 10 A Central server for communicating with a user equipment via a common Internet Protocol (IP) address through at least one cellular network, being communicatively coupled with said at least one cellular network by means of a Packet Data Network Gateway (PDN-GW) via Internet, said central server being configured to provide an interface for a service provider on said at least one cellular network and exchange information relating to at least one preconfigured qualifier assigned to at least one user equipment being assigned to the central server, and to receive a payload item from said cellular network transmitted by said user equipment to said cellular network responsive to a measurement result by means of an authentication failure message to communicate smart-metered data to said service provider, for authenticating said user equipment on said cellular network during an attach process started by the user equipment comprising the payload item for cost optimizations; wherein said payload item is the result of a measurement of a sensor connectively coupled to the user equipment when operating as an Internet of Things (IoT) smart-metering device. ### Claim 11 (depends on 10) The server of claim 10, wherein said payload item results from a latest measurement data of said user equipment operating as an Internet of Things (IoT) device regularly transmitting data to said central server. ### Claim 12 (depends on 1) The server of claim 1, wherein the attach process is started by the user equipment with an attach request message and synchronized to a base station to receive the attach request message, wherein a parameter of the attach request message is a preconfigured qualifier indicative of a subscription of the user equipment, wherein the preconfigured qualifier is a permanent identifier either an IMSI or MSISDN. ### Claim 13 (depends on 1) The server of claim 1, wherein the authentication failure message is sent instead of receiving a SMS. ### Claim 14 (depends on 1) The server of claim 1, wherein the authentication failure message is sent instead of establishing an IP connection with said user equipment.
