Mobility Measurements in Connected Mode
LTE Handover Architecture
Handover Types WCDMA •
Intra-RAT Handover -
Intra-frequency - Intra Node B: softer HO for R99 / HSUPA, hard HO (serving cell change) for HSDPA - Inter Node B: soft HO for R99 / HSUPA, hard HO (serving cell change) for HSDPA
•
Inter-frequency: hard HO in any case
Inter-RAT Handover: hard HO either to PS or CS domain in any case to -
GSM
-
WLAN
-
To LTE not yet supported
Handover Types LTE •
Hard HO in any case, no SHO
•
Intra-RAT Handover –
Intra eNodeB
–
Inter eNodeB
•
Data forward forwarding ing ove overr X2 •
High performance for 15…120 km/h
•
Optimized performance for 0…15 km/h
If no X2 interface configured between serving and target eNodeB, than HO via S1 interface (will be available with RL20 RL20))
Inter-RAT Handover - Only to PS domain - HO to WCDMA will be available with RL20 - HO to GSM will not be available, as GSM CS domain
Handover Types LTE other RAT intersystem HO
intersystem HO
triggered by other RAT
triggered by e.g. - coverage of E-UMTS - service
E-UTRAN macro cell
- load
Inter frequency HO
E-UTRAN micro cells
Intra-frequency HO
intra-frequency HO
(intra eNB)
(inter eNB, inter MME)
Handover Procedure -> Lossless –
Packets are forwarded from the source to the target
-> Network-controlled –
Target cell is selected by the network, not by the UE
–
Handover control in E-UTRAN (not in packet core)
-> UE-assisted –
Measurements are made and reported by the UE to the network
-> Late path switch –
Only once the handover is successful, the packet core is involved
Handover Procedure Before handover S-GW + P-GW MME

Handover preparation S-GW + PGW MME

Late path switching S-GW + P-GW MME
Handover Algorithm •
•
•
•
•
A Handover will be initiated by a measurement report sent via the RRC protocol Upon the reception of this measurement report, the handover algorithm will decide whether a handover should take place In response to the handover decision, the handover execution will be carried out using the corresponding procedures After the handover execution, the handover algorithm will be informed, whether the handover was successful or not The Handover procedure is composed of a number of single functions: - Measurements - Filtering of measurements - Reporting of measurement results - Hard handover algorithm - Execution of handover
Handover Algorithm
Handover Events WCDMA •
•
Soft(er) Handover -
1A: A non active cell enters the reporting range, the network tries to add it to the active set
-
1B: An active cell leaves the reporting range, the network tries to drop it from the active set
-
1C: An active cell becomes worse than a non active one, the network tries to replace the active cell by the non active one
Hard Handover (NSN implementation) -
1F: All active cells become worse than an absolute threshold (either RSCP or Ec/Io)
-
6A: The UE transmits with too high power
-
The radio link needs too much power on DL
-
The SIRtarget on UL is at maximum
-
The serving cell has too high load
-
Another carrier or system matches better the user service than the serving one
Handover Events LTE •
Intra-RAT Handover (NSN implementation) -
Currently based on RSRP only, but not on RSRQ
-
Events for intra-frequency HO - A3: A LTE neighbor becomes better than the server according a relative offset - A5: The server becomes worse than an absolute threshold and a LTE neighbor better than another absolute threshold
-
Events for inter-frequency mobility - A2: The serving cell becomes worse than an absolute threshold (triggers redirection, not real handover)
- Event based inter-frequency handover will be available •
Inter-RAT Mobility •
•
Event based inter-RAT handover Analog to the inter-frequency case redirection towards WCDMA or GPRS/EDGE can be done on the basis of event A2

S hort Functional Des cription LTE 54 / Intra LTE Inter eNB Handover via S 1 Interface
S1 based handover is only applicable for inter-eNB handover LTE inter-eNB handover can be executed without X2 interface usage in following scenarios: - No X2 connectivity existing between Source and Target eNB (or blacklisted by operator) - MME or S-GW change required when routing via Core Network User data traffic and signaling messages are indirectly send via core nodes (MME and S-GW) For UE there is no difference whether HO is executed via X2 or S1 interface Feature has an impact on dimensioning and is taken into account in ANTdim tool

•
Redirection is triggered, if the coverage of the server is below threshold4 for at least the time given by a2TimeToTriggerRedirect
•
Event A2 may be triggered, if e.g. the coverage goes dow n because no target cell can be found for handover triggered by event A3 or A5

Event A2 Based Redirection •
Must be enabled with actRedirect (LNBTS, off/on, on)
•
The number of potential target layers is set with redrtId (REDRT, 1..2)
