  3. Time-slot Relaying based Link Extension (TRLE) • Link extension • for a beacon-enabled PAN with a star topology • TRLE PAN relay residing between a PAN coordinator and devices • provides a one-hop relaying link extension for beacon-enabled PAN • provide multi-hop relaying link extension for the DSME-enabled PAN

  4. Time-slot Relaying • Cyclic-superframe structure for time slot relaying • based on the DSME multi-superframe structure • CAP is divided into • time slots for transmitting a frame to the PAN coordinator (i.e., the prioritized device time slot) • starts after the beacon and continues for a preset number of time slots, macNumPrioritizedDeviceSlot • time slots for transmitting a frame to end devices (i.e., the coordinator time slot) • starts after the prioritized device time slot and continues for a preset number of time slots, macNumCoordSlot • The time slot in CFP is bidirectional • may be pre-assigned or allocated before use.

  5. TRLE Functional Description (I) • Starting TRLE-enabled PAN • Advertising the presence of the TRLE-enabled PAN • Joining the TRLE-enabled PAN • Relaying frames outward or inward • Administrating the relaying path • Diagnosing the TRLE relay • Leaving the TRLE-enabled PAN

  6. TRLE Functional Description (II) • PIB attributes • macDsmeEnabled • macTrleEnabled • macRelayingMode • TRLE specific MAC PIB attributes • macNumPrioritizedDeviceSlot • macNumCoordSlot • macNumBidirectionalDeviceSlot • macRelayingTier • macInnerRelayingOffset • macSyncRelayingOffset • macPanRelayList • macBeaconMissingLimit

  7. TRLE Functional Description (III) • Starting a TRLE-enabled PAN • PIB attributes • set to TRUE: macDsmeEnabled, macTrleEnabled, macRelayingMode • start DSME-enabled PAN • start TRLE-enabled PAN • TRLE-enabled PAN coordinator • is instructed to start by • MLME-TRLE-MANAGEMENT.request primitive • with START type, NumPrioritizedDevice, NumCoordSlot parameters • advertises the presence of the TRLE-enabled PAN • by sending Enhanced Beacon with DSME descriptor IE and TRLE descriptor IE

  8. TRLE Functional Description (IV) • Joining a TRLE-enabled PAN • TRLE PAN relay • after channel scan, selects TRLE-enabled PAN coordinator or inner TRLE PAN relay, • is instructed to associate by MLME-ASSOCIATE.request primitive • is instructed to request a relaying time-slot to TRLE PAN coordinator • by MLME-TRLE-MANAGEMENT.request primitive with JOIN type, TxGrade parameters • sends • a TRLE Management Request command with the Management Type field set to Join • TRLE-enabled PAN coordinator • indicates the reception of a TRLE Management Request command through • the MLME-TRLE-MANAGEMENT.indication primitive with the ManagementType parameter set to JOIN • is instructed to assign time-slot • by MLME-TRLE-MANAGEMENT.response primitive with JOIN type, NumPrioritizedDevice, NumCoordSlot, SyncRelayingOffset, NumBidirectionalDeviceSlot, Bidirectional DeviceSlotList parameters • form a relaying path between TRLE PAN coordinator and TRLE PAN relay • by sending TRLE Management Response command

  9. TRLE Functional Description (V) • Relaying frames in multi-hop • After joining a TRLE path, the next higher layer of the TRLE PAN relay instructs to begin relaying frames • by the MLME-TRLE-MANAGEMENT.request primitive with the RELAY_ON type parameter • TRLE PAN relay • performs frame filtering • determines relaying direction, outward or inward, based on Relaying Tier Identifier field of the TRLE Descriptor IE • updates TRLE Descriptor IE • relays frame on time-slot according to the type of frame and direction

  10. TRLE Functional Description (VI) • TRLE path maintenance • To search for activated devices in a TRLE-enabled PAN • the next higher layer issue the MLME-TRLE-MANAGEMENT.request primitive with HELLO type and DstAddr parameter • To get information on the relaying path configuration to a device • the next higher layer issue the MLME-TRLE-MANAGEMENT.request primitive with PATH type • To leave the TRLE-enabled PAN, the next higher layer • halts the relaying by issuing the MLME-TRLE-MANAGEMENT.request primitive with RELAY_OFF type • request to leave by issuing the MLME-TRLE-MANAGEMENT.request primitive with LEAVE type • After leaving a TRLE path, the next higher layer may disassociate from the DSME-enabled PAN
