Patent ID: 8081596

Claim:
Network architecture comprising: a communication network being operative according to a predetermined cellular communication system and communicating with at least one radio terminal belonging to said communication network; and at least one node connected to said communication network comprising: a set of operating software modules configured for implementing at least one set of elements of a protocol stack for configuring said radio terminal, said radio terminal and said node being provided with respective over-the-air software modules configured for managing an over-the-air connection independent from the predetermined cellular communication system between said radio terminal and said node through said communication network, said node downloading transparently to and independent from said communication network at least one module of said set of operating software modules for configuring at least in part said radio terminal, wherein said downloading includes segmenting the at least one module into blocks, transmitting the blocks from the node to the radio terminal, and limiting the time allowed for performing the over-the-air connection, wherein said set of operating software modules is suitable for reconfiguring at least in part said radio terminal to be operative with a further communication system having different protocols than the predetermined cellular communication system.
