FIELD: supporting user equipment servicing from first to second radio access networks.
SUBSTANCE: base station saves at least any subscriber equipment list identifying all radio access networks whereto respective user equipment service may be transferred. Then base station can transfer information saved for particular user equipment to first radio access network to enable the latter to reliably identify other radio access network whereto service can be transferred prior to executing service transmission. Proposed method is implemented by base station, network base-station component, and network component of radio access network.
EFFECT: enhanced reliability of service transfer.
