LTE / EPC Signalling Training from eXplanoTech

Training is one of the areas we have been focussing on for a long time. Due to lack of bandwidth we have only been offering our training to a selected few customers but we are now expanding further. Here is a sample of LTE / EPS Signalling training

Public training on UMTS and HSPA/HSPA+


We are conducting our first public training on UMTS and HSPA/HSPA+. There are still a lot of people working on UMTS / HSPA / HSPA+ even though quite a lot of focus is being put on LTE.

This course is split into 3 parts and the person attending it can decide which days he wants to attend. The intention is to bring a person with minimal knowledge upto a good speed and to a level where (s)he can become an expert by putting some extra effort.


Discounts available for regular readers of this blog. Please ask.

I am in process of preparing Femtocell training as couple of companies have already inquired. I am thinking of the following topics:

Introduction
  What is a Femtocell
  Why do we need Femtocell
  One-phone, Blue-Phone and BT Fusion
  Different types of femto's including Femto++ and super-femtocell (PicoCell)
State of Market

  Key Players
  Whats going on
Femtocell Network Architecture

  UMA based architecture
  Iub over IP
  Iu over IP
  SIP/IMS based architecture
Security, etc.
Advanced Technical issues

   PNP
   Auto Discovery
   Auto Provisioning
   Cognitive Radio Approach
   Open and Close femtocell
   RF Interference
Femtozone Services
Environment and Health effects


Can anyone suggest anything else?

LTE Training now in good shape


We have recently provided 'Introduction to Long Term Evolution (LTE) and System Architecture Evolution (SAE)' training to couple of companies and have received positive feedback on them.
We also provide with high quality detailed training material that is approximately 150-200 pages for each day of the training
In case if your company or anyone you know is planning some training on LTE, please recommend us.

Push-to-share over MBMS


During one of my MBMS trainings last month in Anritsu, i set everyone a task of defining a service based on MBMS. One of the services mentioned was Push to Talk (PTT) over MBMS.
Theoretically it should be possible to use MBMS for PTT. The voice in the UL is sent via a normal CS RAB. On the Downlink the data is Broadcast using MBMS. Since we would like the data to be sent to a particular set of users, it would be Multicasted rather than Broadcasted. Also this would mean that only the users in a particular Service Area will be able to receive this.
From operators point of view, Service Area should be big enough so that the user is seamlessly able to move a wide geographical area. At the same time it should not be too big because localised services (and adverts) can generate more revenue.
A bit of Googling and i came across some patents that are trying to do the same. Following is an extract from a patent Fresh Patents:
[0009] Use of a PoC application server together with a multimedia
broadcast/multicast service (MBMS) server for providing multicast transfer of
data in the downlink direction has been suggested. In the uplink direction PoC
typically uses Real Time Protocol (RTP) traffic unicast. In the uplink PoC
clients send speech data to the PoC application server, which then directs the
speech data packets either to the MBMS for the downlink leg to those
participants who receive the speech via multicast service or directly to those
recipients who prefer to receive via unicast directly from the PoC server. Use
of multicast in downlink direction improves the spectral efficiency in the case
of group communications with great number of participants. In addition, without
multicast it may not be possible to support large group sizes, if the
participants are located geographically in the close proximity.
Another was a patent on free patents:

0032] Herein, the MBMS service refers to a service for transmitting the same
multimedia data to a plurality of recipients through a wireless network. In this
case, the recipients share one radio channel, thereby saving radio transmission
resources. For example, the MBMS service includes a stock information service,
sport broadcast service, Push-to-Talk (PTT) service, and the like.
In fact C-Mobile is working on something similar. One of their documents highlight the limitations of the current MBMS architecture and suggests how we can improve the architecture in future for B3G Architecture.
My personal feeling is that till the Architecture is eveolved enough, PTT may not be very practical over MBMS but we should be able to use Push-to-share over MBMS. Some interesting short video clip or Breaking News Clip or maybe personal Valentine messages, etc can be shared using MBMS. It now needs to be seen if some operator picks on this idea and how soon.
