Re: Network Information Roadmap

Hello Natasha,Good work! Your roadmap text is quite good and constitutes a good and solid body of work we can build again on. I would definitely like to thank you for putting in time and effort in producing it. I have thoroughly reviewed your write-up and going from what you have now, I'd like to suggest some edits, improvements, and elaborations as you have called for.So basing myself of the fact that we are looking at composing a Roadmap document on the Network Side of things with respect to good Application Development aspects and practices, I am suggesting an attempt to provide a good solid base of information ranging from fundamentals/basics to an emphasis on the very specifics at hand, while casting a tentative vision on future trends and ecosystem relationships in accordance to adhering to good practices for better mobile web applications. With that being said I have tried to make my suggestive and additive edits to your text by highlighting main points and inserting any suggested, modificative text.Please keep in mind. Even though I'd like to be able to proficiently use the the Git Doc editing, I'm quite not familiar with it yet; so I have attached a word doc where you will see all my text contributions and edits to your doc. :-)However in the below, I am giving in an outline/skeleton form a quick description of the suggested roadmad summary points to be included, mentioned or taken into consideration. Those are all reflected in my overall review/analysis of the text as well.
So I think going from your document and this outline skeleton I have derived from, we can build more on it, polish it and refine it to have a finalized and solid roadmap document. I have provided suggestions, sections titles, examples, starting points, etc...  I can work with you on coming up with content for other new sections and we put the whole thing together. So upon going over this, please let me know what are your remarks, concerns and suggestions and we can go from there. So down below will be my revisited or rethought blueprint or table of content for the roadmapAlso the other group member, broader community knowledgeable of the subject matters can also chime in and contribute as well. All comments welcome.
Note:my comments in green relate to existing stuff we can build on or just retouch or improvemy comments in red relate to content that needs to be created and added to the text.

Mobile NetworkOperators Roadmap for Web and Internet Standard Setters and Developers 
Abstract
Introduction
Ø Mobile Operator Networks Overview
§ Mobile Network Architecture Composition -- (should containdescription of Radio Access Networks and Core Networks as you have it in thetext) § Understanding xG ---> Network Standardization( 3GPP, 3GPP2) – (youalso have some relevant info on this in your text – just needs a little morepolishing) § Mobile Operation Scenario – Network Attachmentand Context creation ---> Downgrading (we should elaborate more on your description of theattachment process to different RATs and PLMNs)
Ø Evolution and Current State of Mobile Networks &Communications
§ 2G-GSM – (brieflydescribe 2G Network Technology as you have already done) § 3G-UMTS – (briefly describe 3G Network Technology. I have provided ashort description. You can review it) § 4G-LTE – (Description of 4G-LTE Network Technology along with itscorresponding features – You have a good part of it) § Headway towards 5G -- (as Takeshi pointed, there is preliminary andinitial work that has already started for 5G with even network trials happening,so it’s only right that we include a description section on 5G in here)
Ø Mobile Computing and the “Mobile Web”
§ Mobile Web Performance -- (your text on “HTTP and Mobile Networks is agood one that serves this section well – any additions are welcome) § Mobile Applications Development Aspects andConsiderations -- (here we need to highlight what are the major and most significant mobileweb development practices to be taken into consideration with respect to futureand increased mobile web data traffic and complexity)  § Operators – Developers Implications:  Challenges and Opportunities (as Ilyia G.mentioned, this section can be used to include all the different aspect ofmobile development and performance with respect to all the different challenges)·         Developing Network-friendly applications - ApplicationEnvironmental Adaptability (we can mention the development of network APIs whichdevelopers can leverage) ·        Application Power Consumption profiling inrelation with Radio Resources Management ·        Enhancing Applications and Networks for a betteruser experience (your text sections that are titled "what does this means for developers is perfect for this section)
Ø Evolution Concepts and Novel Paradigms  (in this section we will just complement the above with thenew mobile computing and communications trends that are emerging and their promisingpositive impact on mobile applications, user experience and mobile  network performance) 
§ LTE-Advanced, LTE-U and Carrier Aggregation § SON and Network Management § Mobile CDNs, Caching and OTTs § 5G and NFV § WebRTC and RCS § WLAN/WiFi Offload, Cloud Offload and HetNets § Mobile Edge Computing 
Conclusion---------------------------------------------------------------------------------------------
Also find attached the text doc where I have made all my additions and contributions, which you can work on to re-inject onto the GitHup location for all to access and review. With your guidance, maybe I'll learn a bit more on how to edit documentation directly in GitHub. :-)Looking forward to hearing from you soon.

  Hi all,
I am working on the Network Information Roadmap document again for release for TPAC. Just a reminder: This document aims to provide W3C groups and developers with a broad overview of the evolution of the mobile network between 2015 and 2020. 

I have written the section on "Mobile Operator Network in a Nutshell", does anyone think anything should be added?
Thanks!
Natasha

Text
### Mobile Operator Network in a Nutshell
Mobile operator networks are nicely divided into two main sections:

* Radio Access Network (RAN) - connects a user's device to the Core Network. This includes base station which are often grouped in "tracking areas". A Radio Resource Controller lives within the base station and manages the scheduling of who talks when, allocated bandwidth, the signal power used, the power state of each device, and a dozen other variables.
* Core Network - the Core Network connects the radio network to the interent and manages other functions inbetween including routing traffic and billing. The Core Network receives data from the internet into the PGW (Packet Gateway). The PGW manages any policy and billing and passes the data to the SGW (Serving Gateway) to send to the user. The SGW likely does not know where the user is, so queries the MME (Mobility Management Entity) to tell it which base station and location to send the data to to reach the user.

The external network (internet) is connected to the mobile network via the PGW in the core network. The mobile network responsbility ends here.
