Disclosed is a method comprising transmitting a request for establishing a second non-access stratum connection for a second universal subscriber identity module, wherein the request is transmitted via a radio resource control connection associated with a pre-existing first non-access stratum connection for a first universal subscriber identity module. A first radio resource control reconfiguration message is received indicating one or more data radio bearers to be configured. The one or more data radio bearers are configured for the second universal subscriber identity module. A first radio resource control reconfiguration complete message is transmitted indicating that the first radio resource control reconfiguration is completed.

Establishing multiple non-access stratum connections over a single radio resource control connection

An apparatus comprising at least a first subscriber identity module (SIM) associated with a first network, at least one processor and at least one memory, said at least one memory stored with computer pro-associated gram code thereon, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: detect that the first SIM experiences a radio link failure (RLF) or has moved to out-of-service (OOS) state due to an internal action of said apparatus; include in a report to be sent to the first network information about the detection of the RLF or the OOS state of the first SIM; and include in the report an indication that the detection of the RLF or the OOS state of the first SIM is due to the internal action of said apparatus.

Method for providing self-optimisation data

There are provided measures for enabling/realizing efficient connection control for MUSIM devices, which are communication elements or functions involving multiple universal subscriber identity modules. Such measures exemplarily include obtaining a connection rejection and a connection request inhibition time information in response to a connection request for a first universal subscriber identity module, and applying at least part of the connection request inhibition time information for a second universal subscriber identity module for inhibiting (issuance of) a connection request for the second universal subscriber identity module.
