If answered already sorry for the general question - searched archives and did not see much.
I am wondering if there is support (on any 3G UMTS device) for simultaneous multiple-PDP contexts in NetworkManager. We have Qualcomm-based and other vendor commercial phones and dongles which support multiple-PDP context but no way to have active data over multiple contexts (3 simultaneous is desired). I assume this would require underlying USB driver support which creates virtual USB endpoints that are associated to each pdp which is sent across the physical usb endpoint. I saw Dan Williams' April 2010 blog "Mobile Broadband and Qualcomm Proprietary Protocols<http://blogs.gnome.org/dcbw/2010/04/15/mobile-broadband-and-qualcomm-proprietary-protocols/>" which gives some hints about how this might be done for QC Qmi interface and know from generic web search that multiple-PDP context support has been done this way. Maybe just last note - specific need is to send simultaneous flows over 3 PDP contexts. The creation and configuration of multiple contexts via AT-commands is known. If there is any specific information as to status in NetworkManager feedback would be greatly appreciated. Thanks, J. Baranowski
