When and how default and dedicated bearers established in LTE?

Question

Hi Folks,

I am trying to create multiple dedicated bearers for UE with same tft set. Is it possible to have same tft set for multple dedicated bearers.?

The reason for asking this is I am actually facing a problem while creating multiple dedicated beares. As soon as second dedicated bearer established for UE, UE is sending Bearer Resource Modification with cause (Regular Deactivation). Couldn't able to find why it is happening.!

Please provide some suggestions..

Thanks.

Answer 1

when UE is attached to LTE network then default bearer is established. After that if UE want to create any other bearer with same apn then this will be created as dedicated bearer. UE can connect 3 apn at a time. Suppose UE want some services that is not supported by existing apn then in this case UE can try to connect with other apn. The first bearer established with the new apn would be default bearer and any other bearer created after that would be dedicated bearer.
