Claim:
1. A method for inter-working between different wireless technologies, wherein a base station complying with a standardized wireless radio access technology provides wireless connectivity via a particular communication interface to at least one user mobile terminal also complying with said standardized wireless radio access technology, said method comprising connecting said base station with a Mobility Management Entity (MME) and/or a Serving Gateway of an Evolved Packet Core of a third Generation Partnership Project (3GPP) standard technology by performing following steps: using a Non Access Stratum function included in said base station that collects a Media Access Control (MAC) address of the at least one user mobile terminal and further generates an international mobile subscriber identity (IMSI) based in said collected MAC address; providing, by said Non Access Stratum function included in said base station, upon receiving from said MME an identity request for said at least one user mobile terminal, said generated IMSI via a S1 interface and based on a Non Access Stratum (NAS) protocol to a Non Access Stratum function included in said MME, said MME being in communication with a Home Subscription Server; storing, by said Non Access Stratum function included in said base station, said generated IMSI together with a set of parameters and algorithms; performing, between said Non Access Stratum function included in said base station and said MME and Home Subscription Server, an authentication and ciphering procedure of said at least one user mobile terminal by using said stored set of parameters and algorithms; and performing, by said Non Access Stratum function protocol in said base station, the termination of Non Access Stratum protocol messages with said MME, for management of mobility, paging and location procedures related with said at least one user mobile terminal, wherein said standardized wireless radio access technology and said 3GPP standard technology are different wireless technologies, and wherein said authentication and ciphering procedure at least comprises sending, by said Non Access Stratum function included in said base station to said Non Access Stratum function in said MME, a S1 setup request message comprising a Global eNB ID information element that includes an identifier categorizing said base station as a 3GPP standard technology uncompliant.
