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.
Claims27
A method of wireless communication, comprising:
- receiving, at a wireless terminal, from a source node, a radio resource control (RRC) message indicating use of a simultaneous connectivity mobility of the wireless terminal during a mobility procedure from the source node to a target node until the source node is released,
- wherein the indicating use of the simultaneous connectivity mobility indicates keeping connections with both the source node and the target node, and
- wherein the indicating use of the simultaneous connectivity mobility of the wireless terminal includes indicating a per radio bearer basis simultaneous connectivity mobility indicator;
- and
- performing, by the wireless terminal, the mobility procedure based on the RRC message.
