Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.
