Abstract
A User Equipment (UE) communicates with one or both of a first 3GPP core network and a second 3GPP core network over one or both of a 3GPP access and a non-3GPP access. The communication includes: receiving, from the first 3GPP core network, a reject message; and searching for another suitable cell or another suitable Access Point (AP), when the reject message is received over the 3GPP access or the non-3GPP access and the UE is registered with the first 3GPP core network or the second 3GPP core network over the 3GPP access or the non-3GPP access.
Claims20
A User Equipment (UE), comprising:
- a wireless transceiver, configured to perform wireless transmission and reception to obtain one or both of a 3rd Generation Partnership Project (3GPP) access and a non-3GPP access;
- and
- a controller, configured to communicate with one or both of a first 3GPP core network and a second 3GPP core network over one or both of the 3GPP access and the non-3GPP access via the wireless transceiver, wherein the communication with one or both of the first 3GPP core network and the second 3GPP core network comprises:
- receiving, from the first 3GPP core network, a reject message without integrity protection;
- and
- searching for another suitable cell or another suitable Access Point (AP), when the reject message is received over the 3GPP access or the non-3GPP access and the UE is registered with the first 3GPP core network or the second 3GPP core network over the 3GPP access or the non-3GPP access.
A method for handling a non-integrity-protected reject message, executed by a UE communicatively connected to one or both of a first 3rd Generation Partnership Project (3GPP) core network and a second 3GPP core network over one or both of a 3GPP access and a non-3GPP access, the method comprising:
- receiving, from the first 3GPP core network, a reject message without integrity protection;
- and
- searching for another suitable cell or another suitable Access Point (AP), when the reject message is received over the 3GPP access or the non-3GPP access and the UE is registered with the first 3GPP core network or the second 3GPP core network over the 3GPP access or the non-3GPP access.
