Abstract
Methods and apparatuses involve a network node (22) of a wireless communication network (10) and a wireless device (12) attempting redirection with respect to the network (10). An overall bound limits how many times or for how long the wireless device (12) attempts redirection and provides a mechanism for the wireless device (12) to extend its redirection efforts to one or more redirection targets beyond those indicated by the network (10).
Claims29
-33. (canceled)
A method performed by a User Equipment (UE), the method comprising:
- receiving a Radio Resource Control (RRC) release message indicating redirection of the UE;
- attempting the redirection towards one or more indicated redirection targets, as indicated in the release message, subject to an overall limit that bounds an overall number of redirection attempts made by the UE towards the one or more indicated redirection targets, or bounds an overall time allowed for the redirection attempts made by the UE towards the one or more indicated redirection targets;
- and
- upon reaching the overall limit, attempting the redirection towards one or more further redirection targets, wherein at least one of the further redirection targets is not among the one or more indicated redirection targets.
A User Equipment (UE) comprising:
- communication interface circuitry configured for sending signals to and receiving signals from radio access nodes of a wireless communication network;
- and
- processing circuitry operatively associated with the communication interface circuitry and configured to:
- receive a Radio Resource Control (RRC) release message indicating redirection of the UE;
- attempt the redirection towards one or more indicated redirection targets, as indicated in the release message, subject to an overall limit that bounds an overall number of redirection attempts made by the UE towards the one or more redirection targets, or bounds an overall time allowed for the redirection attempts made by the UE towards the one or more indicated redirection targets;
- and
- upon reaching the overall limit, attempt the redirection towards one or more further redirection targets, wherein at least one of the further redirection targets is not among the one or more indicated redirection targets.
A method performed by a network node of a wireless communication network, the method comprising:
- sending configuration information to a User Equipment (UE), indicating one or more configuration parameter values for the UE to use for triggering a redirection failure recovery procedure while performing a redirection procedure.
A network node configured for operation in a wireless communication network, the network node comprising:
- communication interface circuitry;
- and
- processing circuitry configured to send, via the communication interface circuitry, configuration information to a User Equipment (UE), indicating one or more configuration parameter values for the UE to use for triggering a redirection failure recovery procedure while performing a redirection procedure.
