3GPP RAN and Core Platforms

See also: Developer Exchange.

The project provides configurations, scripts, and integration guides for standing up 3GPP-compliant RAN and Core (5G Core, 5GC) stacks, forming the network infrastructure layer on which the other 5G-MAG reference tools run. It is useful for developers who need a complete 5G system to validate end-to-end media delivery pipelines. 5G-MAG builds these platforms on established open-source projects (Open5GS for the core, srsRAN for the radio) so members can reproduce a working network without commercial equipment. For the fork mapping and full technical detail, see Implementation status.

What's Built​

5G System
Non-roaming 5G System architecture in reference point representation, with Reference ToolsBased on TS 23.501 V20.3.0, figure 4.2.3-2

The Open5GS parts are those whose source directories the fork contains. The UE follows the project's own description of srsRAN_4G as the basis of UE functions for MBS. The figure shows the 5G core and NR; the LTE-based 5G Broadcast side of srsRAN_4G has no figure here. Click the figure to enlarge it.

5G Core Service Consumers​

The platforms also include the 5G Core Service Consumers: reusable libraries and command-line tools that let a media application server use 5G Core services such as the Policy Control Function (PCF) and the Binding Support Function (BSF), and the MB-SMF for multicast and broadcast sessions. They are described in Implementation status and exercised in the Tutorials.

Standards implemented​
