Radio State Issue in MRPM 2019/7/28

MRPM Problem MRPM is about integrated power management for multi-radio MNs Currently on the MN side this is not a problem However standardization may be help MNs save power from network side The network may direct calls in such a way to help multi-radio MNs save power 3GPP is currently working on an entity called ANDSF. MRPM will define additional functionality as 802.21 extensions These extensions would apply to ANDSF only if ANDSF is 802.21-based 2019/7/28

MRPM Scenario Multi-radio MN is roaming in 3GPP & WiMAX networks WiMAX interface is active 3GPP interface is powered off MN is registered in 3GPP MN is doing aggregate location updates for 3GPP using WiMAX interface There are signs for ANDSF support but it is inconclusive to assume its adoption in 3GPP MN received a call on 3GPP core 2019/7/28

MRPM Scenario Additional functionality for ANDSF may be like (3GPP adoption can not be assumed at this moment): ANDSF decides to take the call on 3GPP interface ANDSF signals MN to turn 3GPP interface on 3GPP core sends SIP Invite message to MN’s current BS 2019/7/28

MRPM Scenario ANDSF Mobile Node 2019/7/28 CT : Call Terminator PC : Paging Controller ANDSF - CT CT CT Internet HLR PC PC Operator A Operator A WiMAX Core 3 GPP Core Operator B WiMAX Core WLAN WiMAX Network WLAN WLAN WLAN WLAN 3 GPP Network WiMAX Network Mobile Node 2019/7/28

Radio State What does ANDSF need to accomplish the scenario? Radio state: Power Management (PM) capabilities per link, PM state per link, PM state change commands, PM state change events, for hand off scheduling with high speed mobility, Route Should we keep it distributed? 2019/7/28

MRPM Radio State Two approaches: Centralized: in this case one ANDSF entity which is power management-aware What is required to be kept at PM-aware ANDSF? Distributed: in this case more than one ANDSF entities which are PM-aware What is required to be kept at each PM-aware ANDSF? 2019/7/28

MRPM Scenario What about 3GPP core paging MN? Could ANDSF based signaling be too slow compared with 3GPP paging? 2019/7/28

Thank You! 2019/7/28
