Andre Puschmann	f9589c9c5d	enb,rrc,endc: refactor UE capability enquiry and check ... this patch first makes sure that ENDC is only configured if the UE support it. Second the patch also requests the EUTRA-NR and NR capabilities if the UE indicated ENDC support in its EUTRA caps.	3 years ago
Andre Puschmann	8d2e81ad6f	enb,mac,nr: add basic UE object skeleton ... refactor that also adds a basic UE object to the NR MAC	3 years ago

Francisco	fd3901e4a2	bugfix,srsenb,rrc: delete old context right away after sending Reestablishment msg. ... Following ReestablishmentRequests should use the most recent rnti as old context.	3 years ago
Andre Puschmann	aaffdeb326	rrc,rlc: add method to signal protocol failure to RRC ... general-purpose method for lower layers to signal protocol failures to higher layers, i.e. RRC. In the current case, implement a direct release of the UE (enb) or a reestablishment (UE).	3 years ago
Francisco	3f75538660	rrc,feature: Use t301 to set time that the enb waits for the UE RRCConnectionSetupComplete or ReestablishmentComplete	4 years ago
Francisco	0349949cce	bugfix, handover: disable inactivity timer during s1 handover in target enb	4 years ago
Francisco	8811b7c9a7	fix handling of CRNTI CE in the RRC. The scheduler should not allocate more grants for the new rnti after this point.	4 years ago
Francisco	bfdb0332db	remove undefined methods from rrc_ue	4 years ago
Francisco	46cfdaf9e5	Handle case when old rnti gets removed during RRC reestablishment ... This is achieved via: - keep restarting the inactivity timer whenever a ReestablishmentRequest is received - in case the RRC ReestablishmentComplete is very late and the old rnti was removed anyway, abort RRC reestablishment procedure and release new rnti	4 years ago
Andre Puschmann	b61be7878a	enb,rrc: split RLF counter and timer handling for DL/UL/RLC ... this patch splits the counter and timer handling for PHY DL, PHY UL, and RLC errors and makes sure that, for example, a successful DL does not cancel the UL RLF timer, and vice versa. They all use the same timeout value which is user-configurable.	4 years ago
David Rupprecht	f9c0009d23	Remove setup erabs function	4 years ago
Francisco	9464f36714	make eNB UE release timer after RLF detection configurable	4 years ago

Francisco	cdf72248f3	Reimplement batch-based background object/memory pool ... Main changes: - addition of pool utilities - The node size/alignment and batch allocation threshold are now runtime arguments - object pool and memory pool are not anymore based on the same class. The object pool cannot use intrusive free list because it would overwrite the object memory	4 years ago
Francisco	ec3cd9ffea	adt - added background object pool test, and fix existing bugs related to the creation of pools with objects that are too small to be used in free lists	4 years ago
Francisco	d1c5b000dc	adt - creation of pre-initialized object pool, that leverages the background memory pool allocator	4 years ago
Pedro Alvarez	e1a852d4b8	Split split RLF timer and Inactivity timer	4 years ago
Pedro Alvarez	47135cb75b	Changed counting of KOs to RRC	4 years ago
faluco	54fab314c0	Enhance RRC eNB events: ... - Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum. - Log events for connection, reestablishment, reconfig, reject and release. - Log the corresponding ASN1 message used by each procedure. - Redefine the JSON object for this event to match the new structure. Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.	4 years ago
Pedro Alvarez	8c7aed1f81	Added handling of MSG3 timout exipiry in activity_timer_expired(). Avoid notifying S1AP in that case.	4 years ago

Francisco	20928651c7	created batch allocator that leverages background worker pool	4 years ago
Francisco	290f39d805	fix crnti mac ce handling in the rrc in normal (no handover) case	4 years ago
Andre Puschmann	46d8ed8742	enb,rrc: delay UE release after RLC maxRetx ... this fixes the eNB behaviour when RLC signals maxRetx reached. By directly releasing the UE, we ignore the fact that the UE could still have the reestablishment counters running, so could attempt a reestablishment, which would result in a reject because we would have destroyed the UE context too early. this patch delays the removal of the UE to wait at least until the reestablishment timers are expired.	4 years ago
Pedro Alvarez	976b5c12c1	Releasing the UE when max retransmissions are reached in the RLC. (#2385)	4 years ago

faluco	96c07a69c0	Report the RLF event to the JSON event file in the enb.	4 years ago
herlesupreeth	47fff7226a	Send NAS PDU in E-RAB Release Command and issue RRCConnectionReconfiguration to UE ... This commit addresses the following points - If a NAS-PDU IE is contained in the E-RAB RELEASE COMMAND message, the eNB shall pass it to the UE. - Issue RRCConnectionReconfiguration for the DRB to be removed - Cleaning of DRB in RLC and GTP-U - Fix for Malformed E-RAB Setup Response upon reaching max. DRBs	4 years ago
