Optimized Mechanism for Paging Transmission and Reception
First Claim
1. A method comprising:
- receiving information of a paging area by a user equipment (UE) from a base station in a wireless network, wherein the paging area is a subset of a tracking area;
determining if there is any change between the received paging area and a stored paging area of the UE;
notifying the base station if there is any paging area change; and
receiving paging messages in the paging area, wherein the paging messages are transmitted repeatedly by a repetition number.

Abstract
Methods and apparatus are provided for paging transmission and reception for UEs requiring repeatedly paging. In one novel aspect, the UE reports the status to the MME. UE status information and the corresponding cell ID are provided from eNB to MME. MME sends paging information including the repetition number to all eNBs in the corresponding tracking area when paging the UE. In another novel aspect, a paging area is used for UEs requiring repeatedly paging. The UE receives paging area information, notifies the network, and updates the stored paging area information upon detecting changes between the received and the stored paging areas. In another embodiment, the UE reports its status upon detecting status changes. The eNB stores UE information and forwards it to neighboring eNBs in the same paging area. The eNB pages UEs on its UE list with repetition while paging other UEs normally.

7. A method comprising:
-
storing information of a paging area by a base station, wherein the paging area is a geographic area covered by a cluster of neighboring base stations; storing a user equipment (UE) list comprising UEs requiring repeatedly paging by a repetition number; updating the UE list upon detecting one or more triggering events; and paging the UEs on the UE list repeatedly by the repetition number. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A user equipment (UE) comprising
a transceiver that transmits and receives radio signals via a first radio access link; -
an information handler that stores information of a stored paging area; a paging area handler that receives information of a paging area from a base station when the UE, determines if there is any change between the paging area and the stored paging area of the UE, and notifies the base station if there is any paging area change; and a paging module that receives and processes paging messages in the paging area, wherein the page messages are transmitted repeatedly by a repetition number. - View Dependent Claims (18, 19, 20, 21)
