WIRELESS ACCESS DEVICE AND HANDOVER METHOD

摘要

A radio access device includes a controller signal processing unit (RNSAP unit) that processes a signal exchanged with a radio network controller (RNC); and a switching center signal processing unit (RANAP unit) that processes a signal exchanged with a switching center. The RNSAP unit requests to establish a communication path between the radio access device and the RNC and a communication path between the RNC and a BTS by transmitting a request signal to the RNC. Subsequent to receiving an acknowledgement signal corresponding to the request signal from the RNC, the RANAP unit requests to establish a communication path between the switching center and the RNC. Subsequent to receiving, by the RANAP unit, an acknowledgement signal corresponding to the request signal from the switching center, a communication path between the radio access device and the UE is released.
