Patent ID: 8891501

Claim:
A method for routing user plane data in a mobile network, comprising: establishing a tunnel between an access network and a packet data network (PDN) gateway to interconnect an access network bearer of a user equipment and a PDN gateway bearer of the user equipment; routing data between a Home NodeB of the access network and the PDN gateway through the tunnel; wherein the establishing the tunnel between the access network and the PDN gateway to interconnect the access network bearer of the user equipment and the PDN gateway bearer of the user equipment comprises: receiving, by the access network, a tunnel endpoint identifier of the PDN gateway, wherein the tunnel endpoint identifier of the PDN gateway is sent by a mobility management entity (MME) or a serving GPRS support node (SGSN), and establishing an uplink tunnel corresponding to the tunnel endpoint identifier of the PDN gateway according to the tunnel endpoint identifier of the PDN gateway, so that the access network bearer of the user equipment and the PDN gateway bearer of the user equipment are directly interconnected; further comprising: receiving, by the access network, a user plane uplink address of the PDN gateway, wherein the user plane uplink address of the PDN gateway is sent by the MME or the SGSN, so that the access network establishes an uplink tunnel corresponding to the user plane uplink address of the PDN gateway and the tunnel endpoint identifier of the PDN gateway according to the user plane uplink address of the PDN gateway and the tunnel endpoint identifier of the PDN gateway; and receiving, by the PDN gateway, a user plane downlink address of the access network, wherein the user plane downlink address is sent by a serving gateway (SGW), so that the PDN gateway establishes a downlink tunnel corresponding to the user plane downlink address of the access network and a tunnel endpoint identifier of the access network according to the user plane uplink address of the access network and the tunnel endpoint identifier of the access network.
