Fig. 1 is the flow chart of downstream data processing method embodiment one of the present invention, and as shown in Figure 1, the method for present embodiment can comprise:
Downlink data in step 101, reception HSPA network and the LTE network.
Specifically, present embodiment is to the situation of HSPA network and LTE network colocation site.For instance; The base station equipment of present embodiment can be with the Node B (NodeB in the HSPA network; Hereinafter to be referred as: NB) and the evolved Node B in the LTE network (evolution NodeB, hereinafter to be referred as: eNB) function merges, therefore; The base station equipment of present embodiment both can receive the downlink data in the HSPA network, also can receive the downlink data in the LTE network.
Step 102, the downlink data of part at least in the said downlink data is carried out combined dispatching handle between HSPA network and LTE network.
In the prior art, NB in the HSPA network and the eNB in the LTE network all are independently to the processing of downlink data.Specifically; NB only transmits the downlink data from the HSPA network, and eNB only transmits to the downlink data of LTE network, has no association between the two; Therefore, the throughput of entire system is subject to the HSPA network and the LTE network throughput upper limit separately.And in fact, each operator needs to experience very long period to the employing and the deployment of LTE network, and can't adopt a plurality of LTE networks immediately mostly at the deployment initial stage.By comparison, the HSPA network is comparatively ripe and have a bigger network size.Research shows, when operator adopts a LTE network, in the network of being everlasting, has had existing HSPA network.So, utilize HSPA network and LTE network that the downlink data that sends to UE is carried out the combined dispatching transmission, can effectively improve power system capacity, adapt to the demand that UE quantity constantly increases.
Given this, in the present embodiment, the base station equipment that has merged NB and eNB function can be carried out the combined dispatching processing to the part downlink data in the downlink data of HSPA network and the transmission of LTE network even whole downlink data in HSPA network and LTE network.Therefore, can be the downlink data in HSPA network or the LTE network by the downlink data of part at least of combined dispatching in the present embodiment, also can be the downlink data in HSPA network and the LTE network, and present embodiment does not limit.Combined dispatching in the present embodiment is handled, and can include but not limited to following several kinds of processing procedures:

2, in the HSPA network, send the downlink data in the HSPA network, and in the LTE network, send scheduling from the HSPA network and the downlink data that comes and the downlink data of LTE network itself to UE to UE.
3, in the LTE network, send in the LTE network not by the downlink data of combined dispatching, and in the HSPA network, send scheduling from the LTE network and the downlink data that comes and the downlink data of HSPA network itself to UE.
4, in the LTE network, send the downlink data in the LTE network, and in the HSPA network, send scheduling from the LTE network and the downlink data that comes and the downlink data of HSPA network itself to UE to UE.
Therefore, for the downlink data of handling through combined dispatching, it can effectively utilize HSPA network and LTE network to carry out transfer of data.
Present embodiment; Handle through the downlink data of part at least in the downlink data in LTE network and the HSPA network is carried out combined dispatching in HSPA network and LTE network; Can effectively utilize HSPA network and LTE network to carry out transfer of data; Thereby can overcome the restriction that HSPA network and the LTE network throughput upper limit separately brings for the capacity of whole network system, the power system capacity when raising HSPA network and LTE are network coexisted has satisfied the demand that UE quantity increases gradually.Especially for the UE that is in network edge, can effectively improve message transmission rate.
