Open Source LTE Stack srsLTE 18.12 Adds ASN.1 RRC Library, IPv6 Support

Software Radio Systems (SRS) has announced the release of srsLTE 18.12, the latest release of its free and open source Long Term Evolution (LTE) cellular radio software suite, bringing with it IPv6 support and a new Abstract Syntax Notation One (ASN.1) Radio Resource Control (RRC) library.

Designed to offer a full LTE software stack, covering User Equipment (UE), E-UTRAN Node B (eNodeB) base station, Evolved Packet Core (EPC), and supporting common libraries, srsLTE offers compatibility with LTE Release 8 and brings in selected features of LTE Release 9. Tested and validated with a range of network equipment, srsLTE is compatible with Lime Microsystems' LimeSDR family of open software defined radios (SDRs), including those built into the LimeNET range of all-in-one general purpose processing (GPP) and SDR open base stations.

In release 18.12, srsLTE receives a new library for Abstract Syntax Notation One (ASN.1) Radio Resource Control (RRC) use, along with its first support for Internet Protocol Version 6 (IPv6) networking. Other improvements in the latest release include a refactoring of the Evolved Packet Core segment, the addition of encryption support, and numerous fixes to stability and performance across the full software stack.

A full list of changes in srsLTE 18.12 are available in the changelog, while the GNU Affero General Public Licence 3-licensed source code can be downloaded from the project's GitHub repository. For those running Canonical's Ubuntu Linux, pre-compiled binaries are available on Launchpad.
