Abstract
A method of handling non-access stratum (NAS) mobility management (MM) messages for a user equipment in a wireless communication system when the user equipment is configured for dual priority includes sending a first NAS MM request message containing a first priority level to a network in the wireless communication system, and storing a priority indicator indicating the first priority level in a non-volatile memory if the user equipment receives a NAS MM reject message with a mobility management back-off (MMBK) timer from the network.

A method of handling non-access stratum (NAS) mobility management (MM) messages for a user equipment in a wireless communication system when the user equipment is configured for dual priority, the method comprising:
- sending a first NAS MM request message containing a first priority level to a network in the wireless communication system;
- storing a priority indicator indicating the first priority level in a non-volatile memory under a condition that the user equipment receives a NAS MM reject message with a mobility management back-off (MMBK) timer from the network before the user equipment is switched off;
- and
- determining whether the user equipment is allowed to initiate a second NAS MM request message according to the MMBK timer and the stored priority indicator after the user equipment is switched off the then switched on, wherein the information of priority indicator is cleared when the remaining time of the MMBK timer is zero after the UE is switched on again.
A method of handling non-access stratum (NAS) session management (SM) messages for a user equipment in a wireless communication system when the user equipment is configured for dual priority, the method comprising:
- sending a first NAS SM request message containing a first priority level for a specific access point name (APN) to a network in the wireless communication system;
- storing a priority indicator indicating the first priority level for the specific APN in a non-volatile memory under a condition that the user equipment receives a NAS SM reject message with a session management back-off (SMBK) timer for the specific APN from the network before the user equipment is switched off;
- and
- determining whether the user equipment is allowed to initiate a second NAS SM request message for the specific APN according to the SMBK timer and the stored priority indicator for the specific APN after the user equipment is switched off and then switched on, wherein the information of priority indicator is cleared when the remaining time of the SMBK timer is zero after the UE is switched on again.
A user equipment of handling non-access stratum (NAS) mobility management (MM) message in a wireless communication system when the user equipment is configured for dual priority, wherein the user equipment comprises:
- a storage unit, for storing instructions of:
- sending a first NAS MM request message containing a first priority level to a network in the wireless communication system;
- storing a priority indicator indicating the first priority level in a non-volatile memory under a condition that the user equipment receives a NAS MM reject message with a mobility management back-off (MMBK) timer from the network before the user equipment is switched off;
- and
- determining whether the user equipment is allowed to initiate a second NAS MM request message according to the MMBK timer and the stored priority indicator after the user equipment is switched off and then switched on, wherein the information of priority indicator is cleared when the remaining time of the MMBK timer is zero after the UE is switched on again;
- and
- a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
