FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio communications. Method combines procedures of connection and updating of a tracking zone into one new procedure of mobility – procedure of registration.
EFFECT: if the new signal handling function (SHF) can not receive user equipment (UE) data from the old SHF, the new SHF still registers the UE so that the UE does not perform another registration procedure (for example, a connection procedure).
