LTE X2 Handover(X2HO) Call Flow Procedure | LTE eNodeB Handover over the X2 Interface (Eng-Hindi)
HTML-код
- Опубликовано: 6 сен 2024
- • The target eNodeB receives performs admission control on
receipt of the Handover Request.
• The target eNodeB responds with X2AP Handover Request
Acknowledge.
• Information about the accepted RABs is included in the message.
• The Uplink and Downlink GTP Tunnel information is included
for each RAB.
• The tunnel assignments are made at the target to transport
traffic during the handover.
• A Handover Command message sent via a transparent container.
• The source eNodeB send this message to the UE.
eNodeBs in LTE are interconnected with the X2 interface. If two eNodeBs are served by the same MME, handover from the
source to the target eNodeB will take place over the X2 interface.

आनंद जी। आपका प्रयास बहुत ही सराहनीय है। LTE की दुनिया में कदम रखने वालों के लिये बहुत ही उपयोगी है। यही नही,experienced लोगों को भी refresh करने के लिए ये videos बहुत कारगर हैं। कृप्या ऐसे videos बनाते रहें। बहुत बहुत धन्यवाद।
Very clear explanation... With step by step process... Plz prepare more such videos in 5g also
Great Bhut he achha content hai...pls be continued ..I request you pls make a video separate video for RRC connection reconfiguration ..
Plz make video for S1Ho also...
Ur teaching way is so good.. easy to understand..
Sure
@@AnandTechnoSolutions waiting.......pls upload soon
Awesome work. Very well explained X2 HO.👏👏👍
Thanks sagar
nice explanation, same we required for x2ho SR improvement process
Nice lecture
Thanks
Hello sir please prepare Video on S1 interface handover
Great work Anand..... Please make more videos in this simple simplification 👍👍
please make video for S1 handover also
Sure tarun
Very well explained X2 handover. kindly post more videos related to 5G.
Sure..thanks
Very good keep it up bro 👍
really appreciate your hardwork
Thanks
Really very well explained..
Very good
Thanks for sharing detailed information
Thanks Praveen
Excellent work Anand .. I fail to understand why video has 17k views and less than 500 likes.
Yes..Gan..May be mostly people think that i will earn money from like and subscribe so they don't like and subscribe but reality is other things...My intention is create good Video Only....but same people is more interested to Like subscribe TikToK type video frequently
Very useful video
Thank you
Thanks
Please add more videos on MAC layer, NAS, RRC, RLC and RACH
Thnaks
You didn't Cleared End Marker Data Packet and UE Context Release by SeNB, If HO Failed Then How RRC connection Resume will be performed in case if any Critical Situation Faced by UE or TeNB or RACH Failed,
Should be Discussed about MeasEvents Also,
Its a Brief Knowledge but Good,
I appreciate your Effort and Interest,
End maeker is there..please check carefully
Lalan it would be nice if you to share any link where this critical HO is explained in case of failure during execution and Not during preparation
Very nice work 👍🏻👍🏻🙏🏻🙏🏻
Thanks
thanks for the clear explanation
Thanks manasa
Very nicely detailed
Thanks
Very much informative video. Appreciate it. Thanks a lot!!!! What about uplink path?
Thanks
Very Well Explained !!!
Thanks vaibhav
Excellent ...hats off
Thanks Babar
I have seen your last your last video on LTE X2HO which very usefull and got much information and would like to know more on LTE air interface like,,
LTE Uu
S5/S8
S6a
S7
S10
S11
SGi
S1-MME
S1-U
kindly need your favor. thanks
Thank you so much it's helpful can you upload the attach procedure in the same way
Video is available...thanks
great.really helpful
Thanks
Bahut sahi thanks for sharing 👋🏻
Bahut badhiya bhai sahab.
In X2-AP HO Request message I.E's UE AMBR kya hota hain..
Adaptive multi bit rate I think...like we had the different codecs for gsm
Very good explanation
Thanka shankar
Hi Anand is it possible to check from ue side logs whether X2 or S1 HO has been occured?
yes
@@AnandTechnoSolutions ok great which is that message to check please
Excellent
Thanks
Please make video on python & c Programming ,which is used in protocol development /testing with interview question in C.
Sure i will try
Nice sir ji
Thanks
Nice Explane ......sir je
Thanks bro
Thank for detail analysis.. Can u please share same detail of CSFB and Srvcc
Call flow for csfb os already uploaded
EXCELLENT
Thanks...kamal
very nice, but can you provide in word step by step, it will very helpful for us.
Thanks
Thanks for the detailed information 👍... In which case Ue- s1ap-mmeid get changed for a call after x2 call hand over?
X2 is within same Mme.. so changed of MmeUeS1AP id change is not possible i think
Thanks for this great vedio with help of this i have learn HO msg with their IES thank you so much but one doubt i have that i have seen their in PDF and one of interviewer had asked me that mean of UE context release nd its IES so pls help
Hi I need to know i details about tx2 relocation timer expired
Hello Sir,
IN measurement control, ist step, how many object iD would be there? Is this fix or change as per neighbor.
Why we use only A3 for Intra HO, can we use A3 for Inter HO as well?
very good explanation sir
Thanks bro
Sir thoda aram se bol ke samghsiye bahut fast bolte hai aap thx sir......
sure i will improve in next tutorial
Thanks for the informative video.. what purpose does X2 interface serves after x2ho finished and ue starts getting packets from sgw via t eNB ? When this interface gets released ??
After path switch response from mme, Target enb sends UE Context release to Source enb and that is when all the earlier resources including x2 are released
Thanks..Gan has given correct answer..
PLEASE SHARE S1 HO IN LTE ALSO
Sure
Hello Sir, Thank you very much for sharing the valuable information.
I am having one query. During X2 Setup establishment why do we need to use S1MME interface to get the IP address of TeNB, however same can be done using X2 interface as control plane signalling is also there? Please clarify this to me.
Once the X2 setup procedure has been completed by x2 setup response, the X2 interface isoperational.
@@AnandTechnoSolutions OK sir thank you very much, but why SeNB is supposed to send eNB configuration Transfer message to MME? while same also can be done over X2AP-SCTP-IP-L2-L1, Please clarify this to me.
control plane signalling is always there so no need to ask TEID info through MME . it can be done on x2 interface itself
@@yuvrajpatil1710 correct
Could u please tell me what are the reason for X2 handover failure or not trigger with UE end
The most common reason for the HO failure in the execution phase is the Physical sync issue on the Target ENB side and these could be due to late or early trigger of the HO. Primary reasons for the HO failure in the prep phase could be X2 Link issues, configuration issues, Target side Admission control
May cause problem if x2 is not created or Nbr relation table is full
any video on S1 Handover ?
Can you please tell me is "MODIFY BEARER REQ" msg also send by sgw to pgw or sgw directly response to mme "MODIFY BEARER RES."?
Each of these nodes interact with tandem Tunnel IDs.. so only those nodes which have connectivity with target enb require modification.. since pgw only talks with she in both user and control plane so no need to modify those end points. Each node can identify the UE via imsi which was established during the very first transaction the UE made when default EPS bearer was established.
Excellent information Anand.. very nicely explained.. how to ask queries to u ??
Just put the comment...
Its a great video. However your pronunciation is very hard to understand at the rate you speak. It would be better if you speak slow and clear. Thanks for the effort though..
Sure i will try to improve
RUclips has option to slow down video..
Which language is this?
Good but little fastt
please explain in English
Please add ims session... I think u deleted it
Yes due to some reason i have removed
Can you please provide sir. I have to improve on IMS topics
