Abstract:
1. A method of processing commands in a user equipment (UE), the method comprising: receiving by a message handler a security command from a network; upon reception of a received security command from the network, the message handler suspending a currently active security command process in a sequential processor; detecting that processing the received security command will result in a security change in the UE; detecting if there is an existing security command that will result in a security change in the UE (existing security command); if there is an existing security command, rejecting the received security command; otherwise saving the received security command in a command store; resuming operation of the sequential processor so that the sequential processor resumes the suspended security command process if there was one; and the sequential processor processing the received security command if there was no suspended process and the received command was not rejected; and the sequential processor processing saved commands in the command store in the order of reception.
