General BlackBerry® Functions and Features

[Ozzydigital]

Hi All,

I am wondering what exactly is the function of HRT? All I know is it registers your blackberry to your the provider. Is this right?

Also what happends if a BB is already registered to a provider then utilize HRT to register it to another provider will the BB be registered to the 2 providers for BIS?

No, it still takes a PIN to register the device on a carrier, and you can't register a PIN on more than one.

It basically re-registers your device with the NOC at RIM.

Thank you for your replies.

It links you to RIM's servers via your PIN.

HRT registers your device with RIM infrastructure through your wireless network. It also provides required service books for your devices. Service Books enables you to get access to various blackberry services.

The HRT doesn't do any of the things listed. The BB is a mobile device that relies on the presence of a mobile phone carrier's network being available to contact the BlackBerry infrastructure.

Looking at a fixed computer in your office for example - if you try and connect to www.rim.com you'll need to connect through your work network, your work ISP, some backbone, RIM's ISP and then RIM's servers. After you've done this once your work router will remember the path it took as the most efficient. Next time someone looks up www.rim.com the router will say "ah, I know the quickest route there from here".

With the BlackBerry, which moves around a lot, it needs to know the most efficient route from the device to the mast t the GGSN to the network and on to RIM. If you move to a different mast it has to find a different route.  However, when it finds an efficient route it remembers it in the HRT so it doesn't have to work it out again if it finds itself on that mast.

The registration process is completely unrelated to the HRT. Service Books and Services come from something called "Provisioning". Service Books do not control access to the services, they tell the device where to find the servers that will provide the services it requires and how to find them. Access to services is controlled by the infrastructure. If it was controlled by service books everyone would give themselves free services!

Right on the money Martin, thanks for the explanation.

Martin, great information.  They need to get their **bleep** straight.  We shouldn't have to put up with their deficiencies and poor services.  Some day maybe these people will improve but I doubt it.  Don't hold your breath.  I feel like flushing most of these ceL phones down the old **bleep**ter, but don't want to clog it up.  The best thing to do would be to stop buying this stuff and let the industry die.  May it rest in piece or pieces.  Sorry, I had to vent.

I must respectfully disagree. There is nothing fundamentally wrong with HRT as such and there is hardly anything to get straighter than it is already.

There probably is some reason why the HRT is "hidden" in the "Advanced Options". My own guess why so is that HRT is something what enduser should not bother about, like ARP tables in LAN switches or however else they were exactly called (not working for Cisco nor trying to get their blessed stuff to work I personally could not care less)

And Service Books, in terms of BES Blackberry at least, does not seem to have anything to do with cell/mobile network service options as Martin seems to suggest ("free services"). Service Books tell the Blackberry handheld about what stuff is available on the BES and how to use it.

Sorry for bad English, "..this is not a love song, I don't sing my mother tongue"
