This class contains the specification of EPS Bearers.
Introspection did not find any typical Config paths.
See the following references: 3GPP TS 23.401, Section 4.7.2 The EPS bearer 3GPP TS 23.401, Section 4.7.3 Bearer level QoS parameters 3GPP TS 36.413 Section 9.2.1.15 E-RAB Level QoS Parameters
It supports the selection of different specifications depending on the release. To change the release, change the attribute "Release". Please remember that we must expose to all releases the most recent Qci. Asking for Qci parameters for a release in which it has not been created will result in a crash.
For example, if you select Release 11 (or if you don't select anything, as it is the default selection) and then ask for the packet error rate of the NGBR_MC_DELAY_SIGNAL Qci, the program will crash.
Please note that from Release 8 (the latest when the LENA project finished) to Release 11, the bearers ID and requirements are the same. From Release 12, they started to change, and the latest version is now Release 18. However, we do not support intermediate types between releases 11 and 15: in other words, you can select from Release 8 to Release 11, or Release 15 or 18. Any other value will result in a program crash.
The release version only affect Bearer definitions. Other part of the LTE module are not affected when changing the Release attribute.
No TraceSources are defined for this type.

release | The release the user want for this bearer |
Releases introduces new types, and change values for existing ones. While we can't do much for the added type (we must expose them even if the user want to work with older releases) by calling this method we can, at least, select the specific parameters value the bearer returns.
For instance, if the user select release 10 (the default) the priority of CONV_VIDEO will be 2. With release 15, such priority will be 20.
