Re: [OAUTH-WG] [WRAP] WRAP in GSMA OneAPI

[Kevin Smith <[e-mail]>]

Hi David, Blaine,

We (the OneAPI group) have been looking further into OAUTH 2.0 and would
like to see how it can work in a mobile network scenario: for example, a
desktop Web application wants to locate a mobile user to plot their location
on a map. So the client is the Web application and the server is an HTTP
platform sitting on top of the mobile core network.

 It seems that the Web application could register a client ID and client
secret with the OneAPI-implementing server. When location is requested by
this client, the server would prompt the user, and if permission were
received, would enable the client to access the location via an access
token/secret.

One difference to the regular OAUTH flow is that  'post-pay' contract
network subscribers would not have to enter a username/password to identify
themselves since they would be implicitly identified on the network anyway;
they would just need to confirm authorisation ('Allow/Block'). We are not
sure how to handle pre-pay users that buy phone credits in advance.

In case either of you (or any other OAUTH expert) would be available to lead
a discussion on the technology, and to answer questions from mobile
operators and platform vendors, we are having a meeting next Tuesday in
London. The meeting is also accessible over Webex. Please let me know if you
would be willing to do so, as I'm sure it will help kick-start our
implementation work.

Cheers!
Kevin
