Andre Puschmann 6ec573987a remove default value for 'blocking' param from pdcp::write_sdu()
there were two defaults and one was shadowing the other. This
commit removes both defaults and uses blocking-mode for RRC
calls to PDCP in the UE. The eNB write_sdu() uses the non-blocking
mode by default. We have to review the eNB's RRC perhaps and use blocking
there too and non-blocking only for data plane

Andre Puschmann c5f52adfba nas: fix issue in which NAS wouldn't allow to attach once it failed
the main issue was the plmn_selected variable. the solution
was to create a function to enter the deregistered state that resets the variable
and performs all other actions that need to be performed, like clearing
EPS bearers.

The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7

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

RRC-PHY interface (#639)
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Francisco Paisana bb0dbf0f1c created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far. 2019-07-05 10:44:15 +02:00
