Provided is a method to operate a user equipment communicatively connected to at least two subscriber identity modules, which are at least assigned to a first and a cellular network, wherein the user equipment has assigned an independent paging identity in each of the first and second cellular networks for registration in said cellular networks. Other embodiments disclosed.

Method for co-ordination of paging in a user equipment

A system and method for authentication of a secure element cooperating with a Mobile Equipment forming a terminal in a telecommunication network is provided. The telecommunication network comprises a SEAF and a AUSF/UDM/ARPF. The method includes generating an anchor key (K) for the communication between the terminal and the SEAF according to 3GPP TS 33.501, wherein the anchor key (K) is indirectly derived from a key (K) obtained by deriving from the long-term key K and a secure registration token SRT sent by the terminal to the AUSF/UDM/ARPF and concealed with the AUSF/UDM/ARPF public key along with its SUPI in the SUCI. Other embodiments are disclosed.

Method for authentication a secure element cooperating with a mobile equipment within a terminal in a telecommunication network

A method for establishing a communication channel between a local server and a remote server includes: i) transmitting, from the local server to a terminal, the IP address of the remote server and a communication port of the local server; ii) transmitting the IP address of the terminal from the terminal to the local server; iii) transmitting, from the local server to the terminal, a request to connect to the remote server, including the IP addresses of the remote server and the terminal, an identifier of the local server; and the communication port; iv) transmitting, from the local server to the remote server, the IP address of the terminal, an identifier of the local server, and the communication port; and v) combining, at the remote server, the identifier of the local server and the IP address of the terminal to ascertain an IP address of the local server.
