Cell update process with reconfiguration status
View Patent ↗If there is a radio link failure condition ( 330 ) between a user equipment ( 380 ) and a network ( 390 ) during or after a reconfiguration process, a cell update process with reconfiguration status indicates whether a user equipment reconfiguration is complete. If the network ( 390 ) receives an indication that the user equipment reconfiguration is complete, either through a stand-alone reconfiguration complete message ( 320 ) or a status indicator of a cell update message ( 350 ) from the user equipment ( 380 ), the network ( 390 ) proceeds in accordance with the current configuration.
1. A cell update process for user equipment comprising:
reconfiguring the user equipment in accordance with a reconfiguration message from a network;
transmitting a reconfiguration complete message;
experiencing a radio link failure condition;
performing a cell update;
determining if an acknowledgement to the reconfiguration complete message has been received from the network; and
based on the determining, sending to the network a cell update message indicating a radio link failure and that an acknowledgement to the reconfiguration complete message has not been received.
2. A cell update process according to claim 1 wherein the reconfiguration message is a radio bearer setup message.
3. A cell update process according to claim 1 wherein the reconfiguration message is a radio bearer reconfiguration message.
4. A cell update process according to claim 1 wherein the reconfiguration message is a transport channel reconfiguration message.
5. A cell update process according to claim 1 further comprising:
sending to the network a call update message indicating a radio link failure, if an acknowledgement to the reconfiguration complete message has been received.
6. A cell update process for a network comprising:
sending to user equipment a reconfiguration message;
receiving from the user equipment a cell update message indicating a radio link failure;
determining if a reconfiguration complete message has been received from the user equipment; and
based on the determining, sending to the user equipment a cell update confirm message indicating that a reconfiguration complete message has not been received.
7. A cell update process according to claim 6 wherein the reconfiguration complete message is a radio bearer setup complete message.
8. A cell update process according to claim 6 wherein the reconfiguration complete message is a radio bearer reconfiguration complete message.
9. A cell update process according to claim 6 wherein the reconfiguration complete message is a transport channel reconfiguration complete message.
