Method, system and computer program product for inter-working between different wireless technologies

A method, system and computer program for inter-working between different wireless technologies, The method comprising connecting a base station wirelessly connected to a mobile terminal, both complying with a standardized wireless radio access technology, with a MME and/or a SGW of the EPC of the 3GPP standard by means of a NAS function included in said base station. The NAS function collecting a MAC address of the mobile terminal and generating an IMSI identity based on said collecting; providing the generated IMSI to said MME and storing it together with a set of parameters and algorithms; performing, together with said MME or with a HSS an authentication and ciphering procedure of said mobile terminal by using said stored set of parameters and algorithms, and performing the termination of the NAS protocol messages with the MME for management procedures related with the mobile terminal, said wireless radio access technology and said 3GPP standard being different technologies.
