FIG. 1 is a schematic flowchart of a method for data transmission according to an embodiment of the present disclosure, where the method includes:

S101. The multimode base station acquires network standard information supported by the multimode terminal, and determines a network standard information set according to the network standard information supported by the multimode base station and the network standard information supported by the multimode terminal.

Specifically, the multi-mode terminal is a user equipment that can access multiple network standards. For example, the multi-mode terminal can access UMTS, LTE, WLAN, and the like. After obtaining the network standard information supported by the multimode terminal, the multimode base station may further determine a network standard information set according to the network standard information supported by the multimode base station and the network standard information supported by the multimode terminal, where the network The system information set is composed of network standard information supported by the multimode base station and the multimode terminal. Among them, multimode The base station may obtain the network standard information supported by the multimode terminal by using the core network device; or the multimode base station may request the network mode information supported by the multimode terminal from the multimode terminal; or the multimode base station further The connection request message sent by the multimode terminal and carrying the network standard information supported by the multimode terminal may be directly received, so that the multimode base station accesses the multimode terminal to the corresponding network according to the connection request message. At the same time, the network standard information supported by the multimode terminal may be obtained from the connection request message.

S102. The multimode base station establishes, according to the network standard information set, between a data link processing entity of each network standard in the network standard information set and a network processing entity of each network standard in the network standard information set. Data path.

Specifically, the data link processing entity may include a MAC processing entity, an RLC (Radio Link)

Control, radio link control, processing entity, PDCP (Packet Data Convergence Protocol) processing entity, etc., the MAC processing entity, the RLC processing entity, and the PDCP processing entity are all at the data link layer in. For example, the UMTS may include a physical layer, a data link layer, and a network upper layer, and the data link layer of the UMTS may include the MAC processing entity, the RLC processing entity, the PDCP processing entity, and the like, where the MAC The processing entity may correspond to a MAC sublayer, and the RLC processing entity may correspond to an RLC sublayer, and the PDCP processing entity may correspond to a PDCP protocol layer. The network processing entity may correspond to a network upper layer. The multimode base station establishes, according to the network standard information set, a data path between a data link processing entity of each network standard in the network standard information set and a network processing entity of each network standard in the network standard information set. . For example, a multimode terminal has access modes of accessing WLAN, UMTS, and LTE, that is, the network standard information supported by the multimode terminal includes three network standards of WLAN, UMTS, and LTE, and the multimode The base station can also support the three network standards. At this time, the multi-mode base station can establish a data path between each data link processing entity of the multi-mode terminal in WLAN, UMTS, and LTE to each network processing entity.

Specifically, the network status information includes: at least one of interference, air interface quality, and load status. After the multi-mode base station establishes the data path, and when the multi-mode base station performs data transmission with the multi-mode terminal, the multi-mode base station is configured according to each network in the network standard information set. Network state information, selecting at least one of the data paths for transmitting or receiving data, the multimode base station may send data to the multimode terminal through the selected data path, or through selected data. ^ Receive data from the multimode terminal. The multi-mode base station can select a data path according to the interference information, that is, the minimum interference of the network is used as a rule for selecting a data path. For example, the multi-mode base station is the multi-mode in three network systems of WLAN, UMTS, and LTE. The terminal establishes a data path and detects interference information of the three networks. When the interference of the UMTS network is detected to be the smallest, the data path corresponding to the UMTS is selected in the established data path to transmit or receive data, and is detected in a subsequent process.

The multi-mode base station can mutually share data in the access layers of each access mode by establishing a data path between the network standards, so that data that is switched between the access modes is not lost, and the switching is performed. The process becomes smoother.

The multimode base station may further select two or more channels in the data path for transmitting or receiving data, for example, when the multimode base station and the multimode terminal are simultaneously established with WLAN, UMTS, and LTE. When the relationship is connected, the multi-mode base station may further split the data to be sent into two transmission data according to network state information of each network standard, and separately transmit the two transmission data through the WLAN and the UMTS. The multimode terminal transmits data, so that the multimode terminal combines two pieces of transmission data, and the multimode terminal establishes a data path corresponding to the multimode base station between each network system.

If yes, the multi-mode base station combines the transmission data that belongs to the one high-level data received in the at least two data paths; Specifically, when the multimode terminal splits a high layer data into at least two pieces of transmission data, the multimode base station may select at least two data paths to receive the transmission data according to the network status information. When the multimode base station detects that the transmission data belonging to one higher layer data is received in the at least two data paths, the multimode base station may combine the received transmission data to obtain initial high layer data.

In the prior art, if the multimode base station does not receive the acknowledgement packet sent by the multimode terminal, the multimode base station may be caused to resend data to the multimode terminal. Therefore, in the present invention, in order to avoid the phenomenon of data retransmission when the network system is switched, the phenomenon of data retransmission occurs in the multi-mode system provided by the embodiment of the present invention, for example, the multi-mode base station sends data to the In the case of a multimode terminal, the multimode base station may control the multimode terminal to stop generating an acknowledgement packet, and ignore a response procedure initiated by whether the acknowledgement packet is received in the multimode base station. The multi-mode base station may further send a stop confirmation command to the multi-mode terminal, so that the multi-mode terminal stops the acknowledgement processing on the data on the current data path, for example, the multi-mode terminal sends data to the When the multimode base station is described, the multimode terminal may receive the stop acknowledgement command sent by the multimode base station, and ignore the response process initiated by receiving the acknowledgement packet according to the stop acknowledgement instruction. The modulo base station does not generate an acknowledgment packet for the received data.
