Abstract

The invention relates to a method for operating a user equipment with a telecommunications network and for communicating with at least two of a plurality of network functions or services of the telecommunications network or of a further telecommunications network, the plurality of network functions or services being able to provide different kinds of network function functionalities, wherein the user equipment is operated using at least a first non-access stratum communication link and a second non-access stratum communication link, the first non-access stratum communication link being established between the user equipment and a first network function or service of the plurality of network functions or services, and the second non-access stratum communication link being established between the user equipment and a second network function or service, wherein the first non-access stratum communication link involves establishing a first non-access stratum security context between the user equipment and the first network function or service and the second non-access stratum communication link involves establishing a second non-access stratum security context between the user equipment and the second network function or service,wherein the operation of the user equipment, using at least the first and second non-access stratum communication links, comprises the following steps:-- in a first step, the first non-access stratum communication link as well as the first non-access stratum security context is established using a first non-access stratum endpoint information, and the second non-access stratum communication link as well as the second non-access stratum security context is established using a second non-access stratum endpoint information,-- in a second step, the first and second non-access stratum communication links are used between their respective endpoints, wherein a first information element of or transmitted using the first non-access stratum security context is able to be referenced by a second information element of or transmitted using the second considered non-access stratum security context and/or wherein a first information element of or transmitted using the first non-access stratum security context is able to reference a second information element of or transmitted using the second considered non-access stratum security context.
