Embodiment 1
[0056] figure 2 It is a flow chart of the 3G network and 4G network carrier aggregation method in Embodiment 1 of the present invention, such as figure 2 shown, combined with figure 1 , the specific implementation method of the 3G network and 4G network carrier aggregation method in this example is: after the UE accesses through the UU interface with the UMTS system, when both the UE and the eNB support the simultaneous aggregation capability of 3G carriers and 4G carriers, the subsequent RNC judges the need to Allocate the resources of the cell under the LTE system for the UE, then the RNC sends a resource establishment request message to the eNB, requesting the LTE system to allocate resources for this UE, and the eNB allocates resources for this UE, and sends a resource establishment response message to the RNC, and the RNC receives this message Finally, the message allocated by the eNB is configured to the UE through the UU interface signaling. The signaling can be a ph...

[0058] image 3 It is a flow chart of the 3G network and 4G network carrier aggregation method in Embodiment 2 of the present invention, such as image 3 shown, combined with figure 1 , the specific implementation method of the 3G network and 4G network carrier aggregation method in this example is: after the UE accesses through the UU interface with the UMTS system, when both the UE and the eNB support the simultaneous aggregation capability of 3G carriers and 4G carriers, the subsequent RNC judges the need to To allocate resources in cells under the LTE system for the UE, the RNC sends a resource establishment request message to the eNB, requesting the LTE system to allocate resources for this UE, and the eNB allocates resources for this UE, and sends the resource to the UE through UU interface signaling (RRC connection reconfiguration message) The newly allocated resources are configured to the UE. After receiving the air interface signaling (RRC connection reconfiguration...

[0060] Figure 4 It is a flow chart of the 3G network and 4G network carrier aggregation method in Embodiment 3 of the present invention, such as Figure 4 shown, combined with figure 1 In this example, the carrier aggregation method of the 3G network and the 4G network is implemented in the following manner: the UE simultaneously accesses the UMTS system and the LTE system through the UU interface of the LTE system and the UU interface of the UMTS system, and simultaneously aggregates the radio resources of the two communication systems . When the RNC judges that the LTE system resources used by the UE need to be released, it sends a reconfiguration message to the UE through the UU port to release the eNB resources used by the UE. The reconfiguration message can be a physical channel reconfiguration message or a transport channel reconfiguration message, or For the radio bearer reconfiguration message, after the UE releases the relevant resources, it sends a reconfiguration...
