Secure Connection Release and Network Redirection

A method, comprising:

• by a wireless device:
• establishing a radio resource control (RRC) connection with a first cell;
• receiving a RRC connection reject message from the first cell, wherein the RRC connection reject message comprises an indication to redirect the wireless device to a second cell;
• releasing the RRC connection with the first cell;
• determining whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received;
• determining whether a stored configuration indicates to ignore indications to redirect to cells of the specific RAT that are received with a RRC connection reject message prior security establishment;
• in response to determining:
• the security has not been established with the first cell when the indication to redirect the wireless device to the second cell is received, and
• the stored configuration indicates to ignore indications to redirect to cells of the specific radio access technology that are received with an RRC connection reject message prior security establishment,
• ignoring the redirection indication and selecting a new serving cell.

A non-transitory, computer accessible memory medium storing program instructions executable by a processor of a wireless device to cause the wireless device to:

• establish a radio resource control (RRC) connection with a first cell;
• receive an RRC connection release message from the first cell, wherein the RRC connection release message comprises an indication to redirect the wireless device to a second cell;
• release the RRC connection with the first cell;
• determine whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received;
• determine whether a stored configuration indicates to ignore indications to redirect to an insecure cell that are received with an RRC connection release message prior to security establishment;
• in response to determining:
• the security has not been established with the first cell when the indication to redirect the wireless device to the second cell is received, and
• the stored configuration indicates to ignore indications to redirect to an insecure cell that are received with an RRC connection release message prior to security establishment,
• ignore the redirection indication and select a new serving cell.
