Topic: Mobile Networking

17:13:01 [JatinderMann]

Philippe: We have invited Giri Mandyam for Qualcomm Inovation Center, Gunter Klas from VodoPhone and others from ATT to discuss mobile networking performance improvements to include in our next charter.

17:16:55 [JatinderMann]

Gunter: There are many differences between phone operating systems. On application level, to send short messages a lot of over head is required to send signals. Just to send a few bytes to the application server, that can trigger signals between the mobile network and application. This can cause a burden on the network, potentially leading to network outages. The user is also impacted by the increased signaling from the mobile home, as this impacts the

17:19:23 [JatinderMann]

...There have been discussions in many groups about this problem. There are examples of solutions today where the client captures signals on the client side. In terms of trying to solve the problem when the problem has arisen. We have documentation like the Application Developer Guide. But we wanted to work with the standards group.

17:21:45 [JatinderMann]

... Which programming paradigms have what consequences on the mobile networking. We have documentation that covers those specific behaviors in iPhone, Andriod and Windows phones. I feel that there is a gap between HTML5 applications that are running on a phone where the mobile network is impacted.

17:24:10 [JatinderMann]

Giri: With new web technologies, like web sockets, there needs to be battery life concerns. Web sockets are a great replacement to XHRs for keeping a presistant connection to the server. When developers start sending dummy bytes on the sockets, we lose the benefits of power saving modules on the phones. What are the kind of the signaling changes that need to be taken place. Seems like mobile issues are not being concerned to the degree that they should

17:25:46 [JatinderMann]

Gunter: We don't currently have a lot of data on the new web technologies.

17:26:24 [JatinderMann]

Giri: Thats also because these are new technologies and we don't yet have the adoption. But that doesn't mean the Web Perf WG shouldn't be forward looking.

17:27:36 [JatinderMann]

Gunter: It would be good to understand if guidelines for native mobile applications should use the same paradigm as web applications.

17:30:10 [JatinderMann]

plh: We haven't done best practices documentation in this working group, but we have been working on APIs to help improve performance, like battery life, using requestAnimationFrame, Page Visibility, etc.

17:31:16 [JatinderMann]

Giri: In the WebRTC, they are looking at a stats interface where they will provide feedback on rtc, rtp interfaces that will provide data up through JavaScript. Is this something that that working group should use, or is this something the Web Perf WG should look at?

17:32:56 [gmandyam]

Jatinder - WebRTC stats I/F looks at RTCP/RTP performance metrics. Thanks - Giri

17:43:39 [JatinderMann]

Jatinder: We are very interested in mobile performance improvements. Please do send your specific requests to the mailing list so we can discuss.
