Abstract: Techniques to achieve near zero millisecond mobility of wireless terminals are described. In one example method, a wireless terminal receives a radio resource control message from a source node. The message indicates the use of a simultaneous connectivity mobility of the wireless terminal during a mobility procedure from the source node to a target node. The wireless terminal performs the mobility procedure based on the control message.
