Method for applying an alternative authorization method and/or an alternative authentication method to a user equipment requesting access to and/or services from a communication network in case of the user equipment belonging to an internet-of-things user equipment type, wherein the communication network comprises a core network and an access network, and wherein the communication network is able to serve user equipments of different user equipment types, applying different authorization methods and/or different authentication methods for different user equipments belonging to different user equipment types, wherein the user equipment is related to a subscriber identity information and/or to a device identity information, wherein the communication network comprises, as part of the core network, a subscriber repository functionality, the subscriber repository functionality comprising pieces of subscriber identity information and/or pieces of device identity information regarding a plurality of user equipments of different user equipment types, wherein the method comprises the following steps: -- in a first step, the user equipment requests a service from the communication network by means of transmitting a service request message to an access network element or a core network element, the service request message comprising the subscriber identity information and/or the device identity information related to the user equipment and an indication that the alternative authorization method and/or the alternative authentication method shall be applied to the user equipment, -- in a second step, subsequent to the first step - in case that the user equipment belongs to an internet-of-things user equipment type -, the requested service is granted to the user equipment by means of the user equipment receiving a service authorization message from the access network element or the core network element, wherein, prior to the second step, the communication network performs - based on the subscriber identity information and/or the device identity information - a verification that the user equipment indeed belongs to the internet-of-things user equipment type, wherein the verification that the user equipment indeed belongs to the internet-of-things user equipment type is performed by the subscriber repository functionality of the communication network upon at least one further request message (202, 205) transmitted by the access network element or by the core network element to the subscriber repository functionality, wherein at least one further authorization message is transmitted by the subscriber repository functionality to the access network element or to the core network element, wherein the at least one further authorization message comprises an indication that the user equipment belongs to the internet-of-things user equipment type, wherein the subscriber repository functionality generates an additional information element from the subscriber identity information and/or the device identity information related to the user equipment, wherein the additional information element comprises the information whether the user equipment belongs to an internet-of-things user equipment type or not. -- in a first step, the user equipment requests a service from the communication network by means of transmitting a service request message to an access network element or a core network element, the service request message comprising the subscriber identity information and/or the device identity information related to the user equipment and an indication that the alternative authorization method and/or the alternative authentication method shall be applied to the user equipment, -- in a second step, subsequent to the first step - in case that the user equipment belongs to an internet-of-things user equipment type -, the requested service is granted to the user equipment by means of the user equipment receiving a service authorization message from the access network element or the core network element, wherein, prior to the second step, the communication network performs - based on the subscriber identity information and/or the device identity information - a verification that the user equipment indeed belongs to the internet-of-things user equipment type, wherein the verification that the user equipment indeed belongs to the internet-of-things user equipment type is performed by the subscriber repository functionality of the communication network upon at least one further request message (202, 205) transmitted by the access network element or by the core network element to the subscriber repository functionality, wherein at least one further authorization message is transmitted by the subscriber repository functionality to the access network element or to the core network element, wherein the at least one further authorization message comprises an indication that the user equipment belongs to the internet-of-things user equipment type, wherein the subscriber repository functionality generates an additional information element from the subscriber identity information and/or the device identity information related to the user equipment, wherein the additional information element comprises the information whether the user equipment belongs to an internet-of-things user equipment type or not.
