1. A method comprising:
maintaining a database of unique radio network identifiers within a home node B gateway for a plurality of radio nodes controlled by the home node B gateway, wherein the unique radio network identifiers uniquely identify radio network termination points of user equipments attached to the plurality of radio nodes controlled by the home node B gateway, and wherein maintaining the database of unique radio network identifiers comprises:
allocating at least one of the unique radio network identifiers to a first radio node controlled by the home node B gateway; and
in response to receiving at least one user equipment registration request, associating, within the database, the allocated at least one unique radio network identifier to a radio node identifier corresponding to the radio node that is currently storing a user equipment context of a user equipment, wherein the at least one unique radio network identifier is initially assigned to the user equipment by the first radio node,
wherein allocating the at least one unique radio network identifier comprises allocating the at least one unique radio network identifier dependent on determining the number of unassigned unique radio network identifiers associated with the radio node identifier, transmitting the user equipment registration request, is less than a determined threshold.
