Claim of US Patent No. 10,972,999

1. A method for determining a paging area for use in an access network node, comprising:acquiring indication information indicating the allocation of the paging area for a User Equipment (UE);
determining the paging area for the UE in accordance with the indication information; and
notifying the UE of the paging area,
wherein the acquiring the indication information indicating the allocation of the paging area for the UE comprises receiving the indication information indicating the allocation of the paging area for the UE which is transmitted after the UE has moved beyond a current paging area;
wherein the determining the paging area for the UE in accordance with the indication information comprises:
determining whether the UE is allowed to be in the RRC inactive state; and
when the UE is allowed to be in the RRC inactive state, determining the paging area for the UE;
wherein the determining whether the UE is allowed to be in the RRC inactive state comprises:
acquiring the information about the area in which the UE is allowed to be in the RRC inactive state in accordance with the indication information; and
determining whether the UE is allowed to be in the RRC inactive state in accordance with the information about the area in which the UE is allowed to be in the RRC inactive state,
wherein the acquiring the information about the area in which the UE is allowed to be in the RRC inactive state in accordance with the indication information comprises:
transmitting a request to a first access network node so as to acquire the information about the area in which the UE is allowed to be in the RRC inactive state; or
transmitting a request to the core network node so as to acquire the information about the area in which the UE is allowed to be in the RRC inactive state.
