chaning plmn id in lte network

in LteWorld Forum

Hi all,
I have enodeb and MMEi emulators configured on plmn say 311-289
i programmed by sim and UEi to same plmn 311-289.

In wireshark, i see id-TAI and id-EUTRANi-CGI still sending old plmn id but not the new. other items like IMSI in NASi having new PLMNi ID.

So, What else should i change to UE send new plmn id in above messages?

Regarding IMSI paging

in LteWorld Forum

Hi

i need a S1AP interface IMSI paging wireshark log.
where paging must have done with IMSI instead of M-TMSI ue paging ID.

can anyone help me in this regard???

Which parameter used by eNB to decide X2i handover depending on Event A2 measurement ? timeToTrigger or reportAmount or others ?

I want to know how the eNB decide to trigger handover based on Event A2 measurement report.

Questions about Testing the Accuracy of LTE Transmission

in LteWorld Forum

Hi!

We are currently doing some experiments on LTEi by using software defined radio. We write our program in CCS 5 and use the Spectrum Digital emulator to test the program.

Angle of Arrival (AOA) Estimation, Motivation in LTE networks

in LteWorld Forum

Hi all,

As my thesis work, I have estimated AOA in LTEi networks in uplink at eNodeBi. Now i will have my defense on 5th of August.

My problem is " that what is the real motivation for AOA estimation (UEi positioning) in LTE networks"?

Lte log file

in LteWorld Forum

please i need help from any one having experience with logfiles.

I have a log file with some successful handovers, using Genex probe i can know handover parameters like TTT,A3offset, Hysteresis ... but when i try to test the event A3 condition i find that these successful handovers should not have been completed according to the RSRPs of the serving and neighbour cells

4G Rollout

in LteWorld Forum

Hi,

I'm working on the 4G rollout and interworking with legacy 3G networks. Would you please share usefull documents related to this topic?The ouuput of this part is an initial design to deploy LTEi network on an existing 3G/UMTS networks.

Thanks in advance.

MVNO for LTE networks

in LteWorld Forum

All

One point not clear to me wrt MVNO for LTEi networks.

AFAIU, it seems that hybrid "MVNO" may own their own PCRFi to manage LTE networks.
but how does it work when two or morr PCRF manage the same network infrastructure ? problems in terms of QoSi may occure, conflict ?

LTE-Advanced Relay

in LteWorld Forum

In LTEi Relay Network, given the total number of OFDMA resource block to a donor eNode B, and a Relay station is the deployed. Now, suppose the relay station has its own RRM capabilities and has its own Cell ID.

My question is: is the number of resource blocks available in the relay coverage area a subset of the total number of the resource blocks available to the donor eNode B?

Measurements in LTE

in LteWorld Forum

I have the following queries.

1) Are measurement gaps required for intra frequency measurements in LTEi?
2) Can UEi do intra frequency measurements during DRX cycles?
3) What are autonomous gaps? How does eNodeBi come to know of the autonomous gaps used by the UE?

functional node IP address assignment

in LteWorld Forum

Does the spec state that there has to be a unique IP address for each different interface type on a functional node.
So for instance on a combined GSN/SWG/PWG box, would there be different IP address assignments for the different interfaces S1U,S8i,S11 etc... or can it also be just one IP address

scheduling in lte

in LteWorld Forum

Hi everyone, In HSDPA, a BSi can schedule 4 users simultaneously, because there are 4 hs-shared control channel. In LTEi, how many users can be scheduled in a single TTI?

UCI Over PUSCH in TD-LTE

in LteWorld Forum

Hi,

I would like to know when UCI HARQi/RI information is transmitted on PUSCH. How eNb determines how many ACK/NACK or RI bits has been used by particular UEi.
