Multi Cell - L to W Handover
The simplest way to define the word 'handover' would be "chaging the partner".
Who is chaning the partner ?
I meant "UE (Mobile Phone)".
Who is the parter in this case ?
I meant "Cell".
Therefore "Handover" is the process in which UE changes the cell.
Overall logic is simple and this process are the same (or at least very similar) in every technology.
- i) A UE is in connection with a cell (let's call this 'Cell A').
- ii) Now a situation that requires handover happened.
- iii) Network send "signal quality measurement" command to UE for the garget cell ('Cell B') to which it will handover to.
- iv) UE performance the measurement and report the "measurement result" to the network via the current cell (Cell A).
- v) Network evaluate the measurement result reported by UE.
- vi) If the evaluation result turns out to be good for handover, Network send 'Change Cell' command to UE.
- vii) UE perform the cell change process.
- viii) If cell change process is completed properly, UE send 'cell change completion' message to the network via the target cell (Cell B).
I used very generic term e.g, "signal quality measurement command", "measurement result", "Change Cell Command", "Cell Change Completion Message" etc. These generic commands can be translated to a specific jargon for each technology. For example, if I translate these for UMTS, they would be as follows :
"Signal quality measurement command" ==> Measurement Control
"Measurement Result" ==> Measurement Report
"Change Cell Command" ==> Physical Channel Reconfiguration or ActiveSetUpdate
"Cell Change Compeletion Message ==> Physical Channel Reconfiguration Complete or ActiveSetUpdateComplete
If you translate them into LTE jargon, they will be as follows.
"Signal quality measurement command" ==> RRC Connection Reconfiguration
"Measurement Result" ==> Measurement Report
"Change Cell Command" ==> Mobility From EUTRA Command
"Cell Change Compeletion Message ==> Handover To UTRAN Complete
Then you may have whole lots of questions. It is very good. The more questions you have, the more information you will get through this page.. (not now, in the future -: ) Following is a set of my personal questions.
- i) you talked about "Signal Quality Measurement". What kind of signal quality UE has to measure ? Would it be a certain absolute value ? or a some relative value with reference to some other value ? or is it a special event changes ?
- ii) How much time I can leave the current cell to perform the measurement for target cell ? (If the leave too long from the current cell to measure target cell, the call would drop. But if this time is too short, UE would not get correct measurement values).
- iii) What if UE failed to performe the measurement or fail to find the target cell ?
- iv) you talked about "Change Cell", how UE can change cell ? Just cut the connection with the current cell and reconnect to the target cell ? or is there any specific procedure ?
- v) Cutting the connection from the current cell will be easy, but how can UE reconnect to target cell ?
- vi) What if UE failed to reconnect to target cell after he cut off the connection with the current cell ?
This list would get longer and longer.
Now let's jump into detailed technical aspects of LTE to WCDMA handover. Following is the overall and simplest form of LTE-WCDMA handover procedure. It means this is mainly for UE side aspect of Handover process.

Now let's dig into some of the critical steps of this handover process. I will start with radio message for these critical steps and put additional comments as time goes a long.
RRC Connection Reconfiguration for Target Cell Measurement (Step 11)
Following is an example of RRC Connection Reconfiguration with Measurement Configuration. You would see various combinations in details if you look at the logs from live network.

Following is an exampe of Mobility From Eutra Command message. It is super complicated.. it is because it should carry all the information that is required to setup Radio Bearer in WCDMA network. In order for you to understand all the details of the contents, you need to understand all the details of WCDMA Radio Bearer Setup message. If you are really interested in understanding the details, refer to RAB Overview, RAB-Rel 99, RAB-Rel 6, RAB-Rel 7 pages of 2G/3G section.
