# Description #
The purpose of this repository is to provide an updated version of the original OAI code base. The original code base can be found here: https://gitlab.eurecom.fr/oai/openairinterface5g. The updates to the OAI code base removed some latent bugs, added multi-UE scalability, and were tested with a standard bypass proxy between the UE(s) and eNB. The proxy is available at: https://github.com/EpiSci/oai-lte-multi-ue-proxy. With this package, various multi-UE scenarios can be tested without the overhead of PHY-layer features of underlying radios. This proxy was created to allow users to test and utilize EpiSci's updated version of the OAI code.
### Where this all began: ###
OAI code was used to baseline this work. The initial framework for this development was started from the follwoing commit: https://gitlab.eurecom.fr/oai/openairinterface5g/-/commit/362da7c9205691a7314de56bbe8ec369f636da7b.

### Included Fixes: ###
- Ease of use of gprof and address sanitizer for debugging purposes
- Updated json files to allow for GDB, real-time debugging capabilities
- Updated logging features to minimally log only key connection milestones. This imroves scalability of multiple UEs.
- Updated logging to include time stamp for timing analysis
- Updated memory allocation procedures to correct size requirements
- Added debugging features to handle signal terminations
- nfapi.c pullarray8 fix invalid pointer math
- Overlapping destination and source memory in memcpy, so updated to memmove to check for this bug
- Advanced error checking mechanisms in critical pack and unpack functions
- Created option for CPU assignment to UE to improve scalability
- Added EPC integration to allow multiple individual UE entities to each have their USIM information parced by the executables
- Updated random value seeds to minimize probability of error in generation of random values
- Enables capability round robin scheduler if desired
- Enables capability real time scheduler if desired
- Added new standalone functions to the UE phy-layer (phy_stub_ue.c) to incorporate individual UE entities
- Updated sending and packing functions in UE (lte_ue.c) to incorporate new standalone changes
- Incorporated semaphores to control timing of incoming downlink packets
- Implemented new queuing system to handle message exchange from UE to eNB and vice versa
- Updated global value in nFAPI for size of subframe
- Updated global value to increase scalability in system
