Embodiment 1

[0206] As shown in FIG. 2( a ) and FIG. 2( b ), it is a schematic structural diagram of a network system according to Embodiment 1 of the present invention. In Embodiment 1, the AP supports assisting in the transmission of LTE data; in addition, in the network system of the embodiment of the present invention, a converged radio network controller (Single Radio Controller, SRC) for controlling the AP and eNB may also be included, the SRC It can be the same node as eNB (Figure 2(a)), or it can be a different node (Figure 2(b)). If the SRC and the eNB are not the same node, the first and second aggregation indication information in Embodiment 1 of the present invention may be determined by the SRC and sent to the eNB; the SRC may send the first and second aggregation indication information through the X2 interface Instruct the eNB, and then the eNB sends the first aggregation instruction information to the UE, and sends the second aggregation instruction information to the AP. T...

Embodiment 2

[0238] As shown in FIG. 7(a) and FIG. 7(b), it is a schematic structural diagram of a network system in Embodiment 2 of the present invention. In the second embodiment, the AP and the eNB are co-sited or not co-sited, and the AP not only supports the transmission of offloaded LTE data, but also supports the separate transmission of WLAN data. Some UEs served by the eNB perform LTE distribution and aggregation (that is, the UE WIFI module transmits the downlink data received from the AP to the protocol layer of the UE LTE module for processing, or the UE LTE module distributes the LTE data to the WIFI module for transmission), Some perform WIFI service transmission; in addition, in the network system of the embodiment of the present invention, an SRC may also be included, and the SRC and the eNB may be the same node (Figure 7(a)), or different nodes (Figure 7(a)). (b)). When the SRC and the eNB are different nodes, the first and second aggregation instruction information in Em...

Embodiment 3

[0252]As shown in FIG. 11(a) and FIG. 11(b), it is a schematic structural diagram of a network system according to Embodiment 3 of the present invention. Wherein, the AP not only supports assisting in transmitting LTE data, but also supports only transmitting WLAN data. The UE under the coverage of the AP can perform LTE offloading and aggregation and WIFI service transmission at the same time or time-sharing; in addition, in the network system of the embodiment of the present invention, it can also include an SRC for controlling the AP and the eNB, and the SRC and the eNB can be The same node (Figure 11(a)), or different nodes (Figure 11(b)). The corresponding relationship between the value of the identification field and the data type in the third embodiment of the present invention may be determined by the SRC and sent to the eNB, and then the eNB sends the corresponding relationship to the UE and the AP respectively. The corresponding relationship may also be directly det...

Abstract

The present invention relates to the field of communication technologies, in particular to a data transmission method and device, which are used to solve the problem that the continuous transmission of services cannot be guaranteed after the user's services are shunted from one RAT to another RAT, so that The problem of service transmission quality degradation. A data transmission method provided includes: the UE receives downlink data sent by a non-cellular network wireless access device, and determines the data type of the received downlink data according to the first aggregation indication information used to indicate the data type of the downlink data; After determining that the data type of the downlink data is cellular network data, the UE uses a cellular network protocol to process the downlink data. Since the UE can use the cellular network protocol to process the downlink data when receiving the downlink data from the wireless access device of the cellular network forwarded by the wireless access device of the non-cellular network, the integration between different RATs is realized and the continuity of the service is guaranteed transmission, which improves the quality of service transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] With the rapid development of mobile applications, mobile data traffic increases sharply, making it increasingly difficult for current cellular network network resources to meet the demand for increased data traffic. [0003] At present, mobile operators hope to use non-cellular network resources to bear part of the network traffic of the cellular network, so as to alleviate the traffic load of the cellular network. The focus of the current cooperation between the cellular network and the non-cellular network is: under what circumstances all or part of the user's services are offloaded from one radio access technology (Radio Access Technology, RAT) to another RAT. For example, when the long-term evolution (Long Term Evolution, LTE) network service is overloaded, all or part of the service traffic...
