COTS phones seem to send standalone PDN connectivity request
messages even after the initial attach was complete. We don't fully support
them in the EPC but instead of logging a warning we can just send
a reject at least to keep the logs clean.
* Started logger replacement in epc main.
* Replaced loggers in nas and s1ap.
* Replace loggers in nas statics.
* Replaced loggers in s1ap ctx mngmt.
* Replace loggers in s1ap erab mngmt.
* Replaced loggers in s1ap mngmt proc.
* Replaced loggers in s1ap nas transport.
* Replaced loggers in s1ap paging.
* Replaced loggers in mme.
* Replaced loggers in mme gtpc.
* Started removing logger injection in init functions and cleaned up argument passing to nas statics.
* Remove logger injection from mme and s1ap.
* Replaced loggers in the hss class.
* Replaced loggers in gtpc.
* Replaced loggers in GTPU and SPGW.
* Replaced loggers in MBMS.
- Handle received E-RAB S1AP at s1ap.cc.
- Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
- Made RLC add_bearer() function capable of re-creating the RLC entity.
- Send RRC reconfiguration to the UE and reply to the EPC with S1AP
modify bearer response.
This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.
* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.
* moved timers out of the UE MAC
This entails:
* Adding S1AP paging messaging to the MME.
* Adding the Downlink Data Notification, Donlink Data Notification Acknoledgment, and Downlink Data Notification Failure Messages.
* Adding the logic at the GTP-U to detect that Downlink Data notification needs to be sent.
* Proper handling of the new GTP-C messages at the MME GTPC and SPGW GTPC classes
* Add queuing mechanisms at the GTP-U while waiting for paging response. Queue is flushed when paging fails (timeout or other).
* Make sure eNB's SCTP information is properly stored.
* Make sure UE's GUTI information is properly stored.
* Adding timer creation at NAS using timerfd_create
* Adding the ability to add and remove the timer file descriptor to the MME main select loop
* Adding the ability to the MME for the NAS to check if a timer is running
* Adding the timer expiry handling functionality at the MME
