Access control method and user equipment
View Patent ↗The present invention provides an access control method in user equipment and user equipment. The present invention is capable of avoiding meaningless connection requests of RNAU, so as to improve the utilization efficiency of communication resources. The access control method in user equipment includes: if a result of access control check indicates that access is barred, then starting an access barring timer; and if it is considered that the access barring timer is in a non-running state, then determining, according to at least one of conditions, whether to trigger RAN Notification Area Updating (RNAU), where the conditions are as follows: whether a current connected state of the UE is an inactive state; whether an RNAU timer started when the UE enters the inactive state is in an running state; whether a cell in which the UE currently resides belongs to a RAN Notification Area (RNA).
1. A method performed by a user equipment (UE), comprising:
performing access barring check for an access category;
starting an access barring timer for the access category if the UE considers access as barred;
stopping the access barring timer when cell reselection occurs;
considering the barring for the access category is alleviated in a case that the access barring timer is stopped; and
initiating an RRC connection resume procedure when the UE is in RRC INACTIVE state, in a case that the alleviated barring is for the access category which is associated with an RAN Notification Area (RNA).
2. The method according to claim 1 , wherein
within the RRC connection resume procedure, a cause of the RRC connection resume procedure is related to an update of the RNA.
3. A user equipment (UE) comprising:
a processor; and
a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
perform access barring check for an access category;
start an access barring timer for the access category if the UE considers access as barred;
stop the access barring timer when cell reselection occurs;
consider the barring for the access category is alleviated in a case that the access barring timer is stopped; and
initiate an RRC connection resume procedure when the UE is in RRC INACTIVE state, in a case that the alleviated barring is for the access category which is associated with an RAN Notification Area (RNA).
4. The UE of claim 3 , wherein
within the RRC connection resume procedure, a cause of the RRC connection resume procedure is related to an update of the RNA.
