NETWORK AND METHODS TO SUPPORT INTER-DOMAIN MOBILITY IN VIRTUALIZED RADIO ACCESS NETWORK

摘要

A virtualized radio access network comprises a radio access network source node central unit; a radio access network target node central unit; a radio access network source node distributed unit; a radio access network target node distributed unit; a wireless terminal; and change of connectivity controlling processor circuitry. The radio access network source node distributed unit is connected with the radio access network source node central unit over a first packet data domain. The radio access network target node distributed unit is connected with the radio access network target node central unit over a second packet data domain. The wireless terminal is configured to communication across a radio interface with one or both of the radio access network source node distributed unit and the radio access network target node distributed unit. The change of connectivity controlling processor circuitry is configured to change at least control plane connectivity of the wireless terminal from the radio access network source node distributed unit to the radio access network target node distributed unit.
