ofonod is removing the ppp0 interface on HE910

Hello All, After the boot, the ppp0 interface becomes active and no idea what reason the interface is getting removed. I could see the following set of activities, Dec 9 15:25:52 WR-IntelligentDevice ofonod[2439]: drivers/atmodem/gprs-context.c:cgev_notify() cid 1 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/rtnl.c:rtnl_message() buf 0xbfacc4b0 len 988 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/rtnl.c:rtnl_message() NEWLINK len 988 type 16 flags 0x0000 seq 0 pid 0 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/ipconfig.c:__connman_ipconfig_newlink() index 8 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: ppp0 {RX} 28 packets 2847 bytes Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: ppp0 {TX} 35 packets 2150 bytes Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/ipconfig.c:update_stats() service 0x8126db8 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/service.c:stats_update() service 0x8126db8 Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: ppp0 {update} flags 4240 <DOWN> Dec 9 15:25:52 WR-IntelligentDevice connmand[1820]: src/service.c:service_lower_down() ppp0 lower down cgev_notify prints 1, no idea what this means.
