Bonjour,
je dois écrire mon mémoire de master qui porte sur la migration du réseau CDMA2000 1X EV-DO REVA vers la LTEⁱ. Je suis sur la partie stratégie de migration et j'y rencontre d'énormes problémes. Je vous serais trés reconnaissante si vous pourriez me donner un petit coup de pouce.
Cordilament.

Hi,

Please let me know what are the parameters can be modified at LTEⁱ eNodeBⁱ at run time?

I want to simulate & calculate delay in n-nodes network in which nodes are randomly distributed but for simplicity their distance are known.

I want to calculate the time (Latency) in this whole scenario. i.e Propagation delay as well as relaying delay in case of Cooperation be a nearby node.

In TS24.301 P32(4.4.2.1), it said:

The UEⁱ shall mark the EPSⁱ security context on the USIMⁱ or in the non-volatile memory as invalid when the UE initiates an attach procedure as described in subclause 5.5.1 or when the UE leaves state EMM-DEREGISTERED for any other state except EMM-NULL.

hello,

i do master work and my theme is some system aspects of lte implementation on 450 Mhz. so i need help with software. beside, i have to compare it on 450 mhz and on 3 Ghz.. so does anybody know some software for lte that could be useful ? :D

Its like network planning.

5.5.2.1 General
E-UTRANⁱ applies the procedure as follows:
- to ensure that, whenever the UEⁱ has a measConfig, it includes a measObject for the serving frequency;
- to configure at most one measurement identity using a reporting configuration with the purpose set to 'reportCGI';

I cannot understand what reportCGI means. Could somebody tell me?
Thank you~

If you want to know the basic difference between voice over lms and voice over lte then you should contact voice over lte and you will know the very basic and huge difference between them. It is really very beneficial for today's generation. 4g technology has been very common now a days. One can easily understand the difference.

To increase the capacity requirements in the given area, normally capacity booster cells have been installed with limited coverage like (micro/ pico/femto) cells.
With respect to the energy saving features of LTEⁱ, these capacity booster cells can be switched off during low traffic periods and switch-on by demand of traffic. These are communicating through X2ⁱ interface.

Can anybody tell me what is a blacklisted cell?

Hello,
I just want to understand a basic difference between Voice over IMS and Voice over LTEⁱ.
Thanks,

TS 23.401 says that "MMEⁱ/SGSN activate ISR after determining SGW's support for ISR. How MME/SGSN determine SGW's support for ISR is implementation dependent."

How is this usually done ? Is there a command at MME/SGSN that can be configured to denote that a particular SGW supports ISR. ?

Thanks in advance.

Hello all,

I cannot find in 3GPPⁱ R10 and beyond specs clearly says that CCs must be from the same eNodeBⁱ.

can somebody please confirm whether this is the case, if so which specs state this.

In R10 and beyond, will a single MACⁱ entity will perform the scheduling functionality across cells under same eNodeB.

kind regards
Sira

Hi,
I am new in OPNET and want to use it for LTEⁱ network simulation. I want to write a function in the function block (FB, more specifically, in lte_ue_as.function block) that will allow me to find out an eNodeBⁱ for each UEⁱ. Does anyone know how can I find the following information:

1. How to find out the eNodeB's that can cover/ provide service to the current UE?
