Abstract
A data transmission method, including: learning, by a first wireless network node, a bearer type of a downlink packet; and when the bearer type is a signaling radio bearer SRB, sending, by the first wireless network node, the downlink packet to a second wireless network node, so that the second wireless network node performs a function of a Packet Data Convergence Protocol (PDCP) layer on the downlink packet; or when the bearer type is a data radio bearer DRB, performing, by the first wireless network node, a function of a PDCP layer on the downlink packet, and sending the processed downlink packet to the second wireless network node.
Claims8
A data transmission method, comprising:
- receiving, by a first wireless network node, an uplink packet from a second wireless network node, wherein the uplink packet carries a GPRS Tunneling protocol (GTP) tunnel identifier indicating an identity of user equipment, information about a bearer type, and identity of a bearer;
- identifying, by the first wireless network node according to the GTP tunnel identifier, the user equipment, the bearer type, and the bearer that correspond to the uplink packet;
- and
- performing, by the first wireless network node, a function of a packet data convergence protocol layer on the uplink packet;
- and wherein
- the first wireless network node and the second wireless network node are included in a single base station;
- the first wireless network node has a radio resource control layer and the packet data convergence protocol layer;
- and
- the second wireless network node has a radio link control layer, a media access control layer, and a physical layer.
A base station, comprising:
- a first wireless network node;
- and a second wireless network node;
- wherein the first wireless network node has a radio resource control layer and a packet data convergence protocol layer;
- and
- wherein the second wireless network node has a radio link control layer, a media access control layer, and a physical layer;
- and wherein
- the second wireless network node is configured to send an uplink packet to the first wireless network node, wherein the uplink packet carries a GPRS Tunneling protocol (GTP) tunnel identifier indicating an identity of user equipment, information about a bearer type, and an identity of a bearer;
- the first wireless network node is configured to identify, according to the GTP tunnel identifier, the user equipment, the bearer type, and the bearer that correspond to the uplink packet;
- and
- the first wireless network node is further configured to perform a function of the packet data convergence protocol layer on the uplink packet.
A non-transitory computer-readable medium storing instructions that, when executed by a base station, cause the base station to perform operations comprising:
- receiving, by a first wireless network node of the base station, an uplink packet from a second wireless network node, wherein the uplink packet carries a GPRS Tunneling protocol (GTP tunnel identifier) indicating an identity of user equipment, information about a bearer type, and an identity of a bearer;
- identifying, by the first wireless network node of the base station according to the GTP tunnel identifier, the user equipment, the bearer type, and the bearer that correspond to the uplink packet;
- and
- performing, by the first wireless network node of the base station, a function of a packet data convergence protocol layer on the uplink packet;
- and wherein
- the first wireless network node and the second wireless network node are included in a single base station;
- the first wireless network node has a radio resource control layer and the packet data convergence protocol layer;
- and
- the second wireless network node has a radio link control layer, a media access control layer, and a physical layer.
