Abstract
Recovering bearers after a service interruption of a relay node includes receiving, at a relay gateway, an instruction to modify bearers from a mobility management entity (MME), the instruction identifying one or more bearers that were in use by the relay node prior to the service interruption, identifying, at the relay gateway, at least one additional bearer in use prior to the service interruption not identified in the instruction received from the MME, and instructing the MME to create the at least one additional bearer. The at least one additional bearer can include a non-GBR bearer, such as a bearer with QCI of 1 used for VoLTE.
