Introduction
Long Term Evolution (LTE) call setup on a Packet Data Network Gateway (PGW) includes GPRS
Tunelling Protocol (GTP) mesages, Create Session Request and Create Session Response, at
both ends of the setup. For the case of rejected calls, Create Session Response may or may not
include a bearer context information element (IE). This article explains why some rejections
include the bearer context, while others do not. This document provides clarification to avoid
potential confusion when troubleshooting and analyzing rejection cause codes on S5/S11
interfaces via packet captures (PCAPs).

Question
The screenshot shown below shows an example of Create Session Response which has two
entries for Cause Code 73 (No resources available) rejection, whereas the second screenshot
has only one entry. Why does this seem inconsistent?
