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.
