Trunk evolved packet core equipment, trunk E-UTRAN Node B and establishing method of trunk bearer

The invention discloses a piece of trunk evolved packet core (T-EPC) equipment, a trunk E-UTRAN Node B (T-eNB) and an establishing method of a trunk bearer, which relate to broadband trunk communication systems based on LTE technology. The method comprises: when a service satisfies bearer establishing conditions, a T-EPC issues a context initialization establishing request, which carries initialization establishing T-RAB information, to a T-eNB, where a piece of trunk user equipment (T-UE) initiating the service is located; the T-eNB establishes an initialized context according to the context initialization establishing request; and after the initialized context is established, the T-eNB sends established radio access bearer information via a configuration message to the T-UE initiating the service, and notifies the T-EPC about the establishment result. The invention also discloses a piece of T-EPC equipment and a T-eNB. According to the technical scheme, a trunk communication system extended from an LTE arch
