Claim 9:
10. A system for recovering bearers after a service interruption of a relay node, the system comprising:
a mobility management entity (MME) configured to generate a modify bearer request in response to receiving a service request, the modify bearer request identifying one or more bearers that were in use by a relay node prior to a service interruption; and
a relay gateway communicatively coupled to the MME, the relay gateway configured to perform operations comprising:
receiving the modify bearer request from the MME, wherein the one or more bearers in the modify bearer request from the MME comprise non-guaranteed-bit-rate (non-GBR) bearers;
identifying at least one additional bearer in use prior to the service interruption not identified in the modify bearer request by referring to a database comprising a list of bearers associated with the relay node; and
instructing the MME to create the at least one additional bearer, wherein the at least one additional bearer is GBR bearer that comprises a voice over long-term-evolution (VOLTE) bearer.
