Clone your own Prince Phil, says eBay seller hawking debris left over from royal car crash

Re: Caught by surprise

He was pulling out at a T junction, and the Kia was barelling down the A road. I suspect it whacked into the rear half of the Land Rover, which would be the lighter end of the vehicle. That probably spun it 180 degrees, maybe the rear wheels sliding to a stop in a soft grass verge on the other side of the road, perhaps digging in and starting the roll at this point in the collision.

Google don't need to do that, they could just publish the data they already collect - your Android phone periodically/sporadically connects to "mobilenetworkscoring-pa.googleapis.com". I wonder for what purpose?

Huawei’s elusive Mr Ren: We’re just a 'sesame seed' in a superpower spat

Re: Luddites = Non Sequitur

Well, I'm sure there are plenty of companies in the world are happy if trade secrets fall into their lap - Huawei may have been a bit more blatant about it (certainly in the past), but equally they have been very canny with their relationships with other companies and their customers in establishing their market position.

In terms of your chain that China isn't very innovative, I think several thousand years of history might disagree. But in the modern day era, specifically, I've been to the Huawei campuses in Shanghai and Shenzhen and they're huge. They have thousands of engineers to throw at problems, and a lot of them are very well educated. The ones I dealt with had to cope with not being allowed to bring materials to meetings (company policy to prevent secrets from leading!) But could still keep in their heads detailed review items for a 600+ page technical requirements document. The added bonus for China is that their labour force is/was so cheap, even for highly qualified staff, so it's not difficult to compete against a Western business which usually has a much higher cost base due to higher employment costs - even if starting from behind the curve.

Re: Pesky microwaves

Have heard of similar things in early mobile phone systems - one story in particular claimed that under certain conditions phones would connect to towers in different cities/towns/rural areas (not sure which propagation environment it was, suspect rural) and play havoc due to the timing offsets required to hit the framing of the phone signals over those distances (100's of km)

Re: Am i being thick...

Perhaps the IP used for the email (and visible in the headers) was traceable (via the ISP) to a router/hub/access point that kept a record of sessions - e.g. commercial Cisco wifi APs will keep records for each device containing MAC address, authentication method, #packets/bytes shipped in each direction, start time and duration (pinch of salt on that one as there's no explicit disconnect in wifi), so all they need to do is get a judge to sign off on a legal "search" of the router to get the logs from it, which are available through a standard API with the appropriate credentials (which no doubt the operator holds).

JetSetJim Silver badge

*if* the manufacturer retained this mapping (and presumably it would be the chipset manufacturer, and not the phone manufacturer as all this stuff is on a single system-on-a-chip like Snapdragons or MediaTek chips), then you can get an IMEI.

IEMI *is* used to authenticate a device when it attaches to the network, and certainly in the EU it is checked against a list of stolen devices so that in theory these are blocked from making calls, and so makes a stolen phone less valuable. I'm not sure how often this check is performed.

However, while IMEI is used to authenticate, it may not actually be stored anywhere - this may be implementation specific, although functionality should be present to do this in a standard EIR. Operators used to forbid non-locked-in phones on their networks, and so they'd need to use IMEI for that, however that's no longer the case, so it may well be that IMEI is no longer reliably stored at the operator for a subscriber. But you may well be able to set a watch for the IMEI so that when it is next used some lights flash, or whatnot, and that would get you the IMSI, and then, if it's not an anonymous pre-pay SIM, subscriber info follows, and call trace/legal intercept/geolocation can be activated for that device, and SWAT teams can swoop on locations...

> Yeah it's actually not. As an emt I've had to use such information as part of my job on the regular(comes over mapped on an MDT), and I've seen the magic software at work in dispatch centres.

Sorry, but that's not the software I'm talking about (that the company I work for sells). Real time geolocation is harder, but getting better, and can still be better than "it's somewhere in this cell". Near real time (15-20 mins) can be scarily accurate. EMT stuff will be behind the times, no doubt, and is limited by the interface back to the network operator.

Re: How hard is the approximate localization of a 2.4GHz sender operating in or near an airport?

It's actually quite easy to do good geolocation based only on the SIM, a variety of companies sell such software to the networks.

JetSetJim Silver badge

Re: How hard is the approximate localization of a 2.4GHz sender operating in or near an airport?

LTE SIMs, while usable and easy to source in an untraceable way, would be geolocateable. Wouldn't be hard to use that to find where the miscreants are by first detecting a SIM in an odd area of the airport and then backtracking to the controlling mobile.

Re: Hmm...

There is a more sensible solution, but the operators won't like it. All that has to be done is separate the effiectively-an-HP-agreement for a new shiny from the phone/data subscription, so that at the end of the HP aspect of the contract, the subscriber drops down onto the pre-agreed contract rate, rather than the current default of keeping the extra payment for the phone going in perpetuity. Mandate that the repayment of the phone subsidy portion of any contract for supply terminates after a fixed period of time. It still allows for the balloon payment if you leave before you've repaid (and then some) the phone subsidy, and makes it quite clear just where your money is going.

It doesn't make enough beer of any type to require vast amounts of bog roll. Back in my student days, I'd brew up a bin-sized (40-60L) amount in a similar time period, and it would be more fun than just inserting a pod and pushing a button.

Re: Boo hoo

I think you've mis-understood the article:

The couple were eventually able to make contact via wi-fi and the emergency 999 number.

Reads like "she collapsed, and tried to ring partner. Call failed, so dialled 999 successfully - presumably this either got routed via another network, or bypassed the bit of s/w that was down. If the latter, then this implies that the s/w had something to do with user authentication, which is not a part of an emergency call setup. Then perhaps Skyped her partner successfully.

All networks *have* to service received emergency calls without doing any user/equipment authentication - indeed phones without SIMs in can make such calls.

Still a pretty shitty thing to have happened.

Re: Form an orderly queue

> if it's just "under" your desk

yup - there's two, mounted in their little boxes, stuffed into a cardboard box with a big pile of cables. Tried to make a little LTE network for the office, using custom programmed SIMs and OpenAirInterface (which includes RAN and Core elements). Could get it to work, but needed GPS antennas to lock the timing sufficiently well. Nice little project. Needed reasonably powerful laptops to drive the radios, though. CN could be run in its entirety off a small laptop - didn't have many SIMs live, so not too much of a hit there. Even managed to get some licensed spectrum to use so that real mobiles could work.

Re: Form an orderly queue

The extra hardware is off the shelf software defined radios that have an amount of FPGA's and take a stock image for 3GPP implementations. I have a couple under my desk at work - these ones. It's not too hard, although I'm not sure a pi had the cpu grunt necessary to power one as lots of fft's are involved with the s/w I used.

UK's BT: It's not unusual to pull Huawei from our core mobile networks

JetSetJim Silver badge

Re: It's Just Retarded!

Huawei are desperate to be a bigger player in western infrastructure and have been playing at it for quite a while. They successfully crippled Motorola's wireless infrastructure business - creeping in from the core outwards.

Surprised they're still allowed as a RAN vendor, but not a core vendor. Wouldn't be surprised if it's possible to develop a compromised/backdoored RAN entity (whatever it might look like) for 5G - particularly as the authentication systems are now knowingly compromised, so a RAN based attack is possible.

Saying that, from a purely capitalist perspective, being blocked from the core isn't likely to be that much of a blow to Huawei - all the money is in the RAN and the s/w upgrades needed for it. They're quite good at giving away RAN kit at cost (or lower), only to EOL s/w quickly, which then needs expensive upgrades (or at least that's my recollection from 10 years ago!)

As long as your brain can issue JSON with the correct formatting, after correctly passing an OAUTH authentication transaction, correctly setting the flags in the subsequent REST queries, you're good to go, then.

JetSetJim Silver badge

Re: what a mess...

As far as I can tell, the API offers exactly what the current VAT submission web page does, but without the ease and simplicity. There are free offerings out there, mainly as an Excel bridge where you just fill in the 9 boxes and probably supply your credentials to submit it.

JetSetJim Silver badge

Reading the REST API for the "submit vat return" (plenty of folk linking the docs), it is literally a JSON formatted 9 box vat return, so complete overkill for a small business which will in no way make your records more accurate as it's the same data you're submitting anyway

JetSetJim Silver badge

Re: Nope

The Flat Rate Scheme still requires a VAT return to be submitted - so yes, you will be affected. All that's different is that the value you send for Box 1 is your flat rate percentage times your revenue, rather than the VAT you've charges, and the box for VAT on purchases is zero (*)

The s/w you use will still need to send the values for the 9 boxes (some may be calculated from the others), it's just that your calculations on what to put in the boxes are different to those not on the FRS.

(*) - something like that, anyway, I've jumped off the FRS as it was no longer worth doing for me (and I think there was some new regulation that made it a pain, but I can't remember what. Anyway, IANAAccountant

I saw it a few weeks ago and despaired at the thought of having to spend cash on s/w to fill in the 7 boxes (mostly zero) of the VAT return. Some googling has found some Excel bridging s/w, but I've not tested them, and am not looking forward to the inevitable cluster-fuck of the first return after this.

HMRC are currently forcing everyone to have some 3rd party solution to submit their VAT returns - pain in the arse. They should publish their own (for small businesses, at least, like their PAYE tools), as well as the API details.

err, if you have a SIM only contract, I'm sure you can sue them into oblivion(*) if they don't let you put it into a device of your choosing. I admit they can tell by querying the IMEI returned via the authentication and encryption routines, but you do at least still have the option of setting your phone to be the "broadband device" by turning on the mobile hotspot function (admitedly probably with limited range in comparison with a proper router). But equally, from your link:
