2 Mobility challenges in femto cell Advertisements –The density of femtocell can be much higher than that of macro cells. –Advertisement for femto cell list is not efficient. Handover –A macro-cell may cover one or several femto cells, when connection is good enough in a macro cell, a MS may not initiate a handover process to access a femto cell. –Since femto cells can have closed access for a limit set of users, most camping/handover requests by the passenger will be rejected. Such frequent futile camping/handover attempts will increase network signaling load and impact end user mobility performance.

3 A two-way handover between macro cell and femto cell When handover from macro cell into femto cell –Challenges listed in previous slide When handover from femto cell into macro cell –Due to the confined range of a femto cell, it needs a fast HO scheme to avoid disconnection Macro cell 1 Macro cell 2 Femto cell 1Femto cell 2

4 Proposal for HO from a macro cell to a femto cell There are 3 steps in proposed mechanism: –Administration of femto cell’s monitoring –Femto cell’s monitoring –Initiate Handover from macro cell to femto cell Administration of femto cell’s monitoring –A femto cell will record the MAC address of its limit set of MSs. If femto cell is open access, then an identifier of no-limitation will be used –The femto cell shall exchange the MAC address of its limit set of MSs to neighboring macro cells. A macro-cell will maintain the mapping between MAC address and corresponding femto cell ID.

5 Proposal for HO from a macro cell to a femto cell (con) Femto cell’s monitoring –Macro cell will notify corresponding femto cell if a allowable MS coming. Verify the MAC address during network entry process. –Macro cell will forward associating uplink resources allocation information of this MS to femto cell. Can be notified by unicast message or force a femto cell to listen the broadcast message of the macro cell –After receiving allocation information, the femto cell can monitor the MS UL data transmission and measure the received signal quality. Received signal quality can include RSSI, SINR, and etc. Initiate Handover from macro cell to femto cell –When monitoring received signal quality is above the threshold, Femto cell will give a request message to the macro cell After receiving this message, the macro cell will originate the handover procedure to handover this MS to requested femto cell

Resources, adjustment) User negotiation (MAC address) Handover Process

7 Proposal for HO from a femto cell to a macro cell When a MS moves from femto cell to macro cell, the target macro cell always has overlapped coverage with the femto cell. –Scanning process of a MS can be skipped or simplified. The femto cell would select the strongest macro cell as the target macro cell. Due to the small coverage of femto cell, the link conditions between a femto cell and a macro cell may be the same as those between MS and macro cell. –The serving femto-cell can provide the link condition parameters to MS such that the MS can speed up DL/UL synchronization during HO process When a MS which is served by a femto cell finds the link is not good –A MS will directly send the handover request message instead of scanning message –A fast synchronization without contention ranging may be applied

9 Proposed text 17 Support for Femtocell [insert the following text] 17.x HO process between femto cell and macro cell 17.x.1 HO from a macro cell to a femto cell A femto cell shall exchange the MAC address of its limit set of MSs to neighboring macro cells. A macro cell will notify corresponding femto cell if an allowable MS performs network (re-)entry with this macro cell. The macro cell will also forward uplink resources allocation information of this MS to femto cell. After receiving allocation information, the femto cell can monitor the MS UL data transmission and measure the received signal quality. If monitoring received signal quality is above the threshold, the femto cell will give a request message to the macro cell to trigger a BS-initiate HO process. 17.x.2 HO from a femto cell to a macro cell When a MS which is served by a femto cell finds the link is not good, a MS will directly send the handover request message instead of scanning message. A fast synchronization without contention ranging may be applied.
