The initial establishment of the upper and lower process creates UE default bearer (Default bearer securities), pursuant to the Agreement (TS 23.401) requirements, core network assigned a bearing when the UE first access PDN bearer will always exist until the UE and PDN scission. This bearing is called the default bearer. In contrast, after the establishment of a default bearer, the same PDN with the UE to establish the other bearer are called dedicated bearer (Dedicated BEARER).
