[BUG] PacketRusher crashes during UE processing if you use a gNodeB id with a hex digit #106

Closed rjaksa closed 3 months ago

Describe the bug PacketRusher crashes during UE processing if you use a gNodeB id with a hex digit in the config.yml file.

To Reproduce Steps to reproduce the behavior:

  1. Verify system is working with decimal gNodeB id in config.yml

tac: "0228BC" gnbid: "000009"

  1. Change gNodeB id to have one or more hex digits in config.yml

tac: "0228BC" gnbid: "00000A"

Expected behavior In case 1 (gNodeB with decimal digits), PacketRusher works fine. In case 2 (gNodeB with hex digits), PacketRusher crashes (but should not).
