ABSTRACT
The SIP-based IP Multimedia Subsystem (IMS), while recently introduced, has become one of the primary distinguishing features of the next generation of mobile telecommunication systems. IMS allows mobile operators to offer advanced value-added services - like VoIP, so-called push-to-media, video, interactive gaming, and mobile banking - to their customers timely and efficiently. Google’s plans to enter the wireless world open up a world of possibilities for offering customers and businesses advanced services such as targeted location-based services and advertisements through the IMS framework.
Deploying IMS, however, is a non-trivial task. The core challenge for the telecom industry has been and will be the integration of the current radio access network (RAN) and IP transport infrastructure with the IMS domain. Within standardization bodies, efforts are underway to address the issues for call setup and mobility signaling, while developing unified user profile management and Quality of Service (QoS) architectures. The real goal is a standardized, IMS-centric, end-to-end unified signaling architecture.
To this end, this presentation provides an overview of IMS and QoS signaling over integrated RAN and IMS domains. By using an exemplary family media service, aspects and specifics of the end-to-end QoS invocation, control and policy enforcement, including roaming scenarios, are demonstrated. Based on laboratory measurements performed at Sprint-Nextel aided with simulations, the Post Dial Delay (PDD) delay is evaluated and some practical recommendations for delay reduction are presented. The presentation will conclude with discussion of open issues and viable solutions. This presentation should be of interest to Googlers who work on mobile related projects and intend to have a big picture of next generation mobile systems such as application development, and service and system integration with wireless operators.
This presentation is based on the article S. Zaghloul, A. Jukan, W. Alanqar: "Extending QoS from Radio Access to all-IP Core in 3G Networks - An Operator’s Perspective," IEEE Communications Magazine, Sept 2007.

In this video, I answer a question from FishTWiT regarding the effect of google voice will have on the telecoms. Google purchased Grand Central which has a lot of features that has one number that forwards to many phones, visual voicemail, and rich filters to route calls based on where calls are coming from. Google voice added SMS, and voicemail transcribing. Yes I think Google voice will have an affect on telecoms. They are positioning themselves to take over the world of telecom. I talk about it more in the video, thanks to FishTWiT for the question.

Tel-domains are an important part of every company’s strategy for the following reasons:
1 - tel-domains playa fundamentally different role than a traditional .com,.net,….Tel-Domains have a very specific and unique content, and are published in a different format and medium (DNS instead of Web). Therefore, Google and other search engines will want to index .tel-domains content in addition to .com content, and will not penalize a company for having both com-domains and tel-domains, as opposed to those that multiply websites under .com, .biz, .co.uk, etc.. This will give companies double presence, with both a .com- and a .tel-domain.
2 - The tel-domains data are fully structured, and therefore very easily readable and understandable by search engine crawlers, as opposed to standard web page content that needs advanced parsing algorithms that often misunderstand the content (reading a fax number as a main number, for example).
3 - Communications content of tel-domains are very easy to maintain, and can be updated at significantly shorter intervals than .com informational content. This gives search engines more incentive to re-index tel-domains content at shorter intervals as well.
4 - Local search engines will index by preference tel-domains data thanks to focus of tel-domains on communications and location information.
