Francisco Paisana 567790c1a2 Renamed struct to store cell context in rrc. Moved sib buffers to this struct. Created helper methods for lookup 5 years ago
Francisco Paisana 349aed5e0d use sib configuration to set SCellToAddModList 5 years ago
Andre Puschmann b7aad27d86 move packing of SCell list into extra method and add fill PHY config on the spot
previously we've packed the RRCReconfig with SCellToAddMod list and have then
parsed the message again to pack the PHY config dedicated for the new SCell carrier. This
is now done in one step.

Pedro Alvarez 96c82b3fc6 Moved PDCP configs to pdcp_config.h. Added `as_security_cfg_t` structure to hold access stratum keys.
Refactored PDCP, RRC and USIM accordingly.

Andre Puschmann 2edecea33e fix SIB transmission for CA
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.

Also avoid MAC calling RLC for each SIB and call RRC directly.

Andre Puschmann 120ad76c63 refactor cell param handling and fix SIB transmissions
- move cell specific eNB params to cell list in rr.conf
- make sure DL EARFCN and DL freq can be used to manually overwrite a single cell config
- fix SIB packing and transmission for multi cell configs
- introduce cell list to MAC
- adapt default enb.conf.example and rr.conf.example

Andre Puschmann fef6893ce4 make user activity handling independent of system time
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.

Andre Puschmann 8a064cd3a6 pass msg_type from caller when logging RRC message
before the type of some message wasn't displayed correctly,
like SIBs, for example because the logger didn't
know the filed to retrieve the type string

Harald Welte 2e426948fe [ENB] Add CFSB support
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Closes: #358
Closes: #363
