Abstract
A method and core network element of a primary network operator (NO) are described for supporting roaming connection signaling messages between a user equipment communicating via a secondary MNO and core network components of a mobile virtual network operator (MVNO) to which an international mobile subscriber identity (IMSI) block has been leased by the primary network operator. The user equipment has a leased IMSI value within a range of IMSI values of the IMSI block, and a roaming services arrangement exists between the primary MNO and the secondary MNO for supporting roaming connectivity of user equipment specifying IMSI values of the primary MNO. The core network element generates an updated connection signaling message by inserting a new destination realm value in a destination field of a received connection signaling message in accordance with a leased IMSI block arrangement between the primary network operator and the MVNO.
