Hi all, We have started to investigate LTE impact on oFono, specifically how to integrate LTE and initial PDN connection, and we have some questions regarding this.
This raises some questions about the handling of ConnectionContexts. When a terminal attach to LTE network it would normally do an implicit context activation request associated to attach request (+CGATT=1). When the context activation is completed this will result in an event notifying about the activated PDN connection according to 27.007 10.1.19 Packet Domain event reporting +CGEREP. +CGEV: ME PDN ACT <cid> At this point we have a "connection context" in the modem. The question is then, how should we model this in oFono? Should we assume/require that a Connection Context already is created by ConnMan and pre-exists in oFono (possibly with a flag indicating that this represents the initial PDN, or perhaps just taking the "internet" ConnectionContext)? Or should oFono automatically create a Connection Context? Furthermore, should oFono automatically proceed and set Active=true, bind the connection to a network interface and set network interface in state UP, or should the ConnectionContext initially set Active=false, waiting for ConnMan to activate it?
