Can Apps Really Damage a Cellular Network? 309

schnell writes "In FCC filings earlier this year, T-Mobile described how the behavior of one Android IM app nearly brought their cellular data network to a breakdown in one city. Even more interesting, the US carrier describes how just the 300,000 unlocked iPhones on their network caused massive spikes in data usage. T-Mobile is using these anecdotes as evidence that mobile carriers should be able to retain control over the applications and devices on their network to ensure quality of service for all users. Do they have a point?"

        Exactly. If they can't deliver a certain level of service, then don't advertise it. I'm not on T-Mobile, but my data plan is clearly marked "unlimited". To me that means, oddly enough, that there aren't any limits on my data usage. If there was a limit, it wouldn't be unlimited. Likewise, if someone has a 1GB plan, then they should really be allowed to transmit that 1GB however they please. If that's not the case, then it needs to be clearly spelled out in the agreement.

        When I was a kid not only were there no cellular phones - you weren't even allowed to own your own wired phone in the US. You had to lease it from AT&T [wikipedia.org] for a monthly fee because Alexander Graham Bell founded that company (sort of - read the prior link for the historic details), and he invented the telephone (this much is not in doubt). It's only recently that we're allowed in the US to bring our own phones to the wireless network, and they've pretty much handled that by making sure that each phone generally works with only one wireless network. We're pretty accustomed to being molested by our communications providers. Only a few years ago it was common to charge more than a dollar a minute to talk to your neighbor across the street if the street was one of the imaginary lines that separated Regional Bell Operating Companies. It was cheaper to call across the country, or even a foreign country, than to organize a meeting of the Parent-Teachers Association (PTA). Back then I bought Karma by subscribing to a cheap long-distance company and performing the contemporary version of bittorrent by serving as a "filebone hub [rxn.com]" on an antique mail and data network called "FidoNet [wikipedia.org]". It was like the Internet except in batch mode and we had parties called Get Togethers (GTs). Back then I was fiending for Internet because I had had it in the military, but couldn't get it because it wasn't available to the general public - only businesses, schools, folks who could afford CompuServ and so on. Get Togethers were a lot of fun because we got drunk, and sometimes naked, in person rather than over video chat. CUCME (see you, see me - an early video chat program) wasn't invented yet - it was the late '80's, or very early '90s. We still stayed anonymous in person mostly - everybody had a "handle" - which nym is taken from a completely irrelevant radio network (Citizen's Band) which will occur later. But I digress.

        Anyway, there was this Georgia peanut farmer, whose name was Thomas Carter (not the former US President Jimmy Carter, as some (formerly including me) believe), who wanted to make phone calls from his tractor in the field. He was electronics savvy, so he rigged up a Citizen's Band radio that would allow him to dial the phone and talk on it, and this was the Carterfone [wikipedia.org] and he sold copies of it, as any right-minded entrepeneur would. And of course AT&T shut him down because they didn't own this thing and so could prevent him from using it on their network. He sued, and it was many years later that his lawsuit resulted in the breakup of the US phone monopoly. That led to AT&T becoming at first just the vestigal long-distance portion of the former phone company, and later just a brand.

        Non-Sequitur: The breakup also led to Unix - which was invented by Bell Labs (a division of AT&T at one point which invented not only Unix and C, but a great many other useful things), being divided into parts. The Unix name was sold to The Open Group, which certifies Unix to this day. The Unix source code and OS was sold first to Novell, which sold it to a quite respectable Linux .com called the Santa Cruz Operation, which burned through their .com millions and sold it off to a spinoff of Novell called the Canopy Group. Actually, they sold it to a spinoff of the spinoff. This story goes on for a long time, and is slowly grinding to an end documented here [groklaw.net]. Unix was the coolest thing that AT&T ever did, and I wanted to work that in even though the code is now owned by a gang of bastards who are determined to ruin every last bit of its utility. But I digress again. Forgive me, it's late.

        AT&T's motto was: "We don't have to care. We're the PHONE COMPANY." The company that owns the AT&T brand now has nothing to

      That's not true.
      UMTS signalling traffic is actually a big worry too.

      Setting up and tearing down radio resource connections all the time has a burden on the network. Mobile applications, with their diverse update patterns (e.g. polling every 30 minutes (email apps), or minute or even few seconds (e.g. IM apps)), can make it difficult for carriers to set up their RRC inactivity timers and various other settings in a way that minimises signalling load on the network.

        Most of the aggressive instant teardowns are due to the criminally-inadequate batteries shipped with the iPhone and every gigahertz+ Android phone that will leave you "powerless" in 4-6 hours without aggressive battery management. If carriers like T-Mobile want to reduce the teardown rate, they could start by telling companies like HTC and Samsung to ship the damn phones with adequately-sized batteries in the first place. It really says something when you go to web forums for high-end HTC, Samsung, and Motorola Android phones, and more or less HALF the postings are directly or indirectly related to battery life. Aftermarket extended batteries are a piss poor option, because the form factor of the phone usually ends of constraining them into an obnoxious tumor-like lump instead of an extra millimeter of overall girth.

        Five years ago, the Samsung SPH-I500 was almost regarded as "fatally flawed" because its battery *barely* could make it through 16-20 hours without a charge. Then Steve Jobs told the world it was normal and OK for phones to die after being away from a charger for 4 hours because it made the phone look thin and sexy, and the entire industry abandoned its common sense and blindly followed with undersized batteries. Fuck, it pisses me off. Imagine how much fun someone like Motorola could have if they'd released the DroidX with a beefy -- yet sculpted and well-distributed -- 3000+mAH battery that enabled it to run full-bore for 24 hours on a single charge with no real power management to speak of. They could have *shredded* the Evo/DesireHD and Galaxy S for dying by mid-afternoon, comparing them to anorexic models competing in the Ironman and dropping dead halfway through, and HTC & Samsung wouldn't have any real recourse besides sending everyone a free battery as an apology, and making sure their NEXT generation of phones had nice, beefy batteries too.

        Hell, they could even resurrect Sir Mix-a-Lot's career for the commercials.

        "When it comes to battlife, SteveJobs got nothin' to do with my selection. Four hours -- maybe six -- not all day? Not MY phone!" (sound of cracking whip amidst dancing troupe of big-backed 'Droids)

      Actually, yes, it is possible.

      You simply flood the network with control messages. That will effectively DoS the tower. What kind of control messages? Well, sending an SMS is a control message. Setting up and tearing down data and voice connections are other control messages, and all are done on behalf of apps.

      Supposedly, one of the major reasons AT&T is having issues with the iPhone is because the iPhone actually does this, a lot. Control channel bandwidth is limited and normally, you don't have much going across it (because it's just call setup/teardown and the like). But with the meteoric rise of SMS and data usage, the control channel actually is in somewhat of a bandwidth crunch.

      Europe and Asia have no problems with iPhones as they've gone to a dynamic bandwidth control channels because of the popularity of SMS. North America until recently didn't need to. So now control channels are somewhat packed with text messages, and you introduce the iPhone with its aggressive power management that tears down data connections ASAP. So a data channel might be established and torn down to view one web page or whenever an app requests data. Most phones prior to this created a data channel and hung onto it until it idled for a long period of time (after all, you're billed by the packet, so keeping the data channel open costs nothing, and it means it's always ready when you need it so you don't have to wait to establish the data channel again and again).

      I can see a few apps that constantly abuse this which can easily take down a network. Setting up/taking down a voice call, setting up/taking down the data connection, do it fast enough and you can really clog up the tower. Enough people do this and the tower can be put out of service because it's stuck establishing and taking down connections so fast that no one else can get in.

      Raw bandwidth wise though, you're not likely to do anything other than slow down due to congestion if the tower's uplink gets saturated.

      In fact, that's what the IM client did - it established and tore down connections very quickly. A phone with aggressive power management (required on Android) would basically be spewing out control messages all day. This can be made more painful if the carrier makes notes in a database for billing purposes.

      T-Mobile network service was temporarily degraded recently when an independent application developer released an Android-based instant messaging application that was designed to refresh its network connection with substantial frequency.

      In other words, this app was continually connecting and disconnecting. It didn't really have anything to do with bandwidth.

      What's funny to me, though, is the solution:

      These signaling problems [...] ended up forcing T-Mobile's UMTS radio vendors to re-evaluate the architecture of their Radio Network Controllers to address this never-before-seen signaling issue. Ultimately, this was solved in the short term by reaching out to the developer directly to work out a means of better coding the application.

      So T-Mobile's UMTS radio vendors learned something. The developer learned something. And T-Mobile's network, ideally, won't suffer from this problem again.

      As a person who used the networks of yore, I can remember many times when the users broke the network. That is why, for instance, outlook has added so many layers of optional protection' like the blocking of attachments and the like.

      I am not sure why everyone, all of the sudden, is forgetting 10 years of DDOS and worm and virus attacks that used to regularly take down networks. We are protected from this not, partly because of more sophisticated software and users, but also because higher bandwidths and lower ping times make such attacks less trivial.

      But ping time and bandwidth and the sophistication of younger users, and older users with no corporate control, make such an attack more probable on a phone network. Ping times on my cell network at about 5-10X as long wifi. Such times might lead to opportunities for rouge apps to degrade the user experience. Combine with lower bandwidth it might be conceivable that we will see some of the same attacks as we did at the turn of the century.

      I am not saying that networks should be closed like Apple, but that until we learn how to use the tools, such disruptions will occasionally occur either accidentally or deliberately. it will be for us to decide if we want to deal with the dropped calls, as we did with the occasionally site becoming unreachable.

      remember, the issue they were complaining about was protocol, not bandwidth.
      the problem they're having would be the same as allowing somebody to attach an FPGA with an ethernet jack to your CAT-6500. as much as you want to limit the port to only allow certain communication: there's nothing stopping the node from abusing the protocol.

      the major difference here is that: the GSM stack assumes you trust your Mobile Stations (MS) because when it was written: telco's had full control over them. TCP/IP has no such restrictions (though I'm sure if you look at the standard long enough you'll find that you can send a physical signal to them in a particular way they will respond in a fashion you don't expect.) the analogy here would be that a GSM BTS acts much like a hub (almost exactly) and when one user keeps storming it with packets, nobody else get's a chance to talk.

      personally: I don't see this as either a telco OR a user issue: it's a protocol issue. we need to take another look at the wireless communication protocol, and find another way of allowing untrusted users their fair access to the medium. (in this case, a pretty narrow band of wireless spectrum). telco's need to push standard-makers/suppliers for something they can sell these days: not some old outdated protocol that allows things like this to happen.

      unfortunately: Air IS like a hub: only one person can talk on it at a time. so it'll be a hard fix.

      Because all the devices you have follow the protocol that all the carriers agree on.

      if you had a rack of ~100 cell phones, that were all able to broadcast rotating IMEI's and SIM ID's of known users, you could single handedly collapse the entire infrastructure for minutes to hours at a time. and based on how the protocol works, it would wreck havoc on the providers. but being a good bunch of people, you don't! so it all just works.

  • do not constitute a reason for me to submit to having which applications I can and can't run decided by a third party.

    Bandwidth should be managed on a user-by-user basis, not an application-by-application basis. If you have an application that sucks up all your bandwidth, then you shouldn't have anymore bandwidth to use. Carriers should advertise burst and long-term bandwidth rates and if you go above the long-term rate you should be subject to having your bandwidth capped at that rate.

    No telling you which application you are allowed to run and which you aren't. No throttling based on port. If you're a customer, you are promised X bandwidth and no more. The carrier is allowed to deliver in excess of that if they so choose, but they aren't allowed to decide you use it for.

    And the carrier should not be allowed to decide on a per-application basis whether or not you get to exceed the bandwidth cap. It must be based on a global, application agnostic bandwidth usage policy that chooses which customers get the extra bandwidth (if any) based on some algorithm that has nothing to do with what their traffic contains.

    T-mobile should have a right to establish radio standards and congestion control protocols and require that any device on the network obeys these standards. They have no right to control end user applications as long as the operating system/radio firmware enforces these standards uniformly. In practical terms it means that apps with sustained high data rate or strict latency requirements may not work, or may stop working when network becomes congested. It's fine as long as "partner apps' also exhibit the same behavior.

    I actually did just read the article and contrary to what many people are posting about, this isn't about data usage and utilization, it's about connectivity utilization and overhead. It seems that similar to opening and closing a database connection there is some overhead in establishing a data connection on a cell phone which is seems is again similar to what happens when you send and SMS. It seems that smart phone development is similar to desktop development in that the application is rarely responsible for creating it's own network connection and instead relies on the OS to handle the network connection. If the phone OS is designed to create and destroy a new data connection for each request then how is that the applications problem. Also, how does a jailbroken iPhone handle data connections differently than a non jailbroken iPhone, the claims made in TFA are just absurd.

    I recall reading somewhere that some European carriers use a different methodology that doesn't create such a bottleneck when these connections are opened and closed. So it seems that once again, the US cell carriers are trying to blame the users of their network for causing problems that would (could, and should) be fixed by upgrading the infrastructure. Cell providers make way too much money to complain about not being able to upgrade their networks.

    The issue with all Cellular networks (and any half duplex shared media) is that the time it takes to send 256 bytes over the air is not 1/4 the time it takes to send 64 bytes, it's more like .6 to .8 times. The signaling setup and tear down takes time to transmit packets over the air, which is fixed no matter the amount of bytes you send.

    This impacts the network as the real bandwidth of a cellular network is not in BPS but airtime. If all the airtime is used up for signaling small packets for marginal sig
