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
this patch allows to configure the EIA and EEA algorithms
the UE uses and announces during attach. They can
be specified as a comma-separated list.
The patch also removes a dedicated NAS config class and uses
the default nas_args_t type for this. There was a full
duplication of members before.
The patch also converts nas_args_t and usim_args_t into a class
with a default constructor that initialize all booleans.
write_sdu and write_pdu are not re-entrant because all functions
that deal with the counters, e.g. integrity check and generate,
must be protected because MAC threads may call them at the same time.
this addresses issue #254
* Starting to add EIA1 tests.
* Initial tests for EIA1
* Bit shifted bearer by 27. Test case 1 and 4 are passing now.
* Adding EIA test case 7.
* Making sure the test is called.
* Fixed double initialization of msg_len_bits.
