RE: Mobile phone capabilities list?





As has been said ... the IMEI can be used to know about the radio device
being used. But that does not assure knowledge of the client capabilities
e.g. laptop / PDA with GPRS card. There is much more than is needed to be
known.

Each mobile device is suppose to have an IMEI ( Blackberry include) i'm not
sure that without IMEI you can register on mobile network ,specialy  when
most of the mobile operators are installing EIR on their network to
blacklist stollen or non compatible device.

Yes is possible to associate IMEI to device capabilities.

This is an interesting point, which brings about two questions:

      -          since you work for O2, I am assuming you know better.
      Honestly, I was assuming that there is no such thing as a device
      without IMEI as long as it is accepted on a carrier’s Network. Don’t
      BlackBerry’s have IMEIs? I know that operators have databases of IMEI
      and they are building services on top of IMEI info.
      -          Does O2 possess a way to associate IMEI to device
      capabilities? if yes, how is this achieved?

So what happens if the mobile device doesn't have an IMEI?

For example, a PDA based browser.

      Yes, this is something we have discussed quite a few times in the
      WURFL community. The idea is to have an extra table to match the
      first part of the IMEI with a WURFL ID. This would allow an operator
      to easily detect device capabilities even without an HTTP Request
      coming from subscriber device.
      The reason why we have not embarked in such a project is that
      developers typically do not have access to a device IMEI to start
      with.
      Having said this, there is increasing interest in WURFL coming from
      operators, so I would say that IMEI support in WURFL is bound to
      happen sooner or later.
      If you like this proposition (and you have a database of IMEI to
      share and expertise in the field), please contact me offline. We
      could work together on this for the developer community’s benefit.

      Thanks

      well in the way i see it most mobile development today, are least for
      phones, are made towards content delivery and related things so u
      usuallay need full information about phonecapabilities i mean gprs
      type, Egprs type, Audio compatibility, video compatibility and so on.
      It will be very difficult to fullfill the needs of several companies
      and developers but it would be good to create a more standarized and
      extensible model to do it. It would be also great to improve IMEI
      databases cause if we think uaprofs are difficult to deal with,
      imei's are impossible. Its there any project to try to merge this two
      identifiers. In the end both of then are usefull to describe the same
      device, at least when we talk about cell phones.

      Several companies create and maintain their own validated device

      with the hope that their experience may be applied to the situation
      that you suggest is the case today. An extensible, accurate,
      verified, trusted baseline repository of device descriptions is one
      of the items on the table, which requires the participants to examine
      carefully how such a repository might operate. Much of the work will
      be conducted with input from the wider community, so I welcome and
      encourage the feedback expressed on the public lists.

      Formally, these are certainly the right standards/groups, but the
      track record is disappointing in practise. In my experience, the
      UAProf info actually supplied is not necessarily accurate or
      complete. The URLs are not always present or correct. There is no
      mechanism or procedure for correcting it - its entirely at the
      manufacturers' whim. Even when the data are ok, there's a lot of
      useful parameters missing from the standard. There's supposed to be a
      Java API, but I had to report a bug in the JSR reference
      implementation months after it was approved. It's very frustrating to
      anyone actually trying to cater for all the different devices right
      now. Standards are one thing, but to get something working, now,
      WURFL is the only show in town. I'm not an open source zealot, but
      WURFL has gone further faster than the standards bodies. It works as
      advertised, it's responsive, it's simple to use, it's user extensible
      .

       The UAProf information, where provided and validated, can provide
       some essential and objective information about mobile devices. It
       has been recognised, however, that in many domains of content
       authoring and adaptation that such information is insufficient. The
       DDWG will be exploring the bigger picture, and looking at ways that
       a general device description repository could be achieved, such that
       it can encompass UAProf and other sources of information, avoiding
       replication of services, and providing the necessary features of
       discovery, trust, efficiency and related information management
       issues. The DDWG is specifically directed to liaise with UAProf and
       other related groups to this end. Planned W3C Notes will explain in
       further detail, and these shall get a public airing during this
       year. Input from interested parties via the public mailing list will
       be encouraged. The group will also solicit specific information from
       key parties where appropriate.

       I hope this adds some clarity.
