21-07-0258-00-00006 Requirements Signaling gains. MRPM shall provide signaling gains on the air interface compared with single radio systems. MRPM also shall provide signaling gains in the network Power Gains The standard shall reduce the power consumption on the mobile terminal compared with single-radio systems The power gains from paging on the active interface The power gains on the location updates on the active interface Power gains on the idle mode signaling of various interfaces using a single interface Information Discovery The standard shall provide services to obtain information needed during idle mode operation. These services shall include mechanisms to obtain detailed information about each interface parameters of the mobile station
21-07-0258-00-00007 Requirements Security The standard shall provide a means to securely signal idle mode entry/exit, paging request and location update requests. The messages will have regular and secure versions. These messages may be obtained from the existing single-radio messages by certain extensions that will be defined in the standard Power Management The standard shall support effective device power management by employing battery efficient network scanning procedures. Wherever applicable the standard shall select network scanning opportunities to coincide with scheduled wake times to minimize the expended power by switching between the active and power save modes of operation for the wireless media employed
21-07-0258-00-00008 Architectural Elements Architecture is based on 802.21 MRPM is viewed as an extension of 802.21 Architectural Elements: MRPM Enabled MIH Function MRPM Enabled Information Server (MRPM-IS) MRPM Paging Agent (MRPM-PA) and MRPM Paging Coordinator (MRPM-PC)
21-07-0258-00-00009 Architecture MRPM PA: AP/ BS MRPM PC MRPM Enabled Information Service
21-07-0258-00-000010 Reference Model 802.21 layering
21-07-0258-00-000011 Scenarios Paging on active interface. Location update on active interface. Idle mode signaling for multiple interfaces Other scenarios.
21-07-0258-00-000012 Paging on Active Interface Example: User is browsing on the Wi-Fi interface, User gets a VoIP call on the WiMAX interface, WiMAX network needs to page the user Wake up WiMAX interface using Wi-Fi BS/AP Paging Announcement Primitives: IEEE 802.21 MS receiving Paging Announcement Primitives: IEEE 802.21
21-07-0258-00-000013 Location Update on Active Interface Example: User has WiFi connection that is currently active and WiMAX connection that is idle Instead of contending on the WiMAX airlink, MS uses the Wi-Fi radio to perform location update for its WiMAX radio BS/AP Location Update Request/Response Primitives: IEEE 802.21 MS Location Update Request/Response Primitives: IEEE 802.21
21-07-0258-00-000014 Idle Mode Signaling Example: Multiple radios are being switched to idle mode For example: when the user takes a break, his WiMAX, WiFi and 3G connections may go into idle mode IM Entry/Exit for radios i, j, k happens on radio-i MS Enter/Exit Idle Mode Request/Response Primitives: IEEE 802.21 BS/AP Enter/Exit Idle Mode Request/Response Primitives: IEEE 802.21
21-07-0258-00-000015 PAR & 5C Proposal is to work on drafting PAR and 5C Discuss them on Thursday Improve them in calls during September-October 2007 Work on a tutorial on MRPM Need volunteers and contributions
