1. A method of wireless communication, comprising:
- receiving a multimedia broadcast multicast service (MBMS) service from a first cell in a first multicast broadcast single frequency network (MBSFN) area while in a radio resource control (RRC) idle mode;
reselecting to a second cell through an intra-frequency cell reselection upon moving into coverage of the second cell;
determining whether the second cell is a non-MBSFN cell or an MBSFN cell in a second MBSFN area different than the first MBSFN area by determining whether a system information block 13 (SIB13) is acquired from the second cell, wherein when it is determined that the SIB13 is acquired from the second cell then it is determined that the second cell is the MBSFN cell in the second MBSFN area different than the first MBSFN area, and wherein when it is determined that the SIB13 is not acquired from the second cell then it is determined that the second cell is the non-MBSFN cell; and
continuing to receive the MBMS service directly from the first cell while receiving paging signals from the second cell.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives an MBMS service from a first cell in a first MBSFN area while in an RRC idle mode. The apparatus reselects to a second cell through an intra-frequency cell reselection upon moving into coverage of the second cell. The second cell is a non-MBSFN cell or an MBSFN cell in a second MBSFN area different than the first MBSFN area. The apparatus continues to receive the MBMS service directly from the first cell while receiving paging signals from the second cell.

46. A non-transitory computer-readable medium comprising code that when executed on at least one processor causes the at least one processor to:
-
receive a multimedia broadcast multicast service (MBMS) service from a first cell in a first multicast broadcast single frequency network (MBSFN) area while in a radio resource control (RRC) idle mode; reselect to a second cell through an intra-frequency cell reselection upon moving into coverage of the second cell; determine whether the second cell is a non-MBSFN cell or an MBSFN cell in a second MBSFN area different than the first MBSFN area by determining whether a system information block 13 (SIB13) is acquired from the second cell, wherein when it is determined that the SIB13 is acquired from the second cell then it is determined that the second cell is the MBSFN cell in the second MBSFN area different than the first MBSFN area, and wherein when it is determined that the SIB13 is not acquired from the second cell then it is determined that the second cell is the non-MBSFN cell; and continue to receive the MBMS service directly from the first cell while receiving paging signals from the second cell.
