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...

[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...

Abstract

The present invention discloses a carrier aggregation method for a 3G network and a 4G network. A carrier aggregation method for a 3G network and a 4G network includes: when the primary radio resource connects to the RRC control anchor and determines to allocate resources of the 4G network for the user equipment UE, notify the secondary The RRC control anchor allocates 4G network resources for the UE. The primary RRC control anchor acquires 4G network resource information allocated by the secondary RRC control anchor to the UE. The invention also discloses a 3G network and a 4G network carrier aggregation system for realizing the above method. The invention enables the UE to use the carrier resources of the 3G network and the 4G network at the same time, realizes the carrier aggregation of the 3G network and the 4G network, and greatly improves the UE speed and resource utilization efficiency.

Description

technical field [0001] The present invention relates to a carrier aggregation technology, in particular to a 3G network and 4G network carrier aggregation method and system. Background technique [0002] In the Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) network, the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) includes a radio network controller (RNC, Radio Network Controller) and a base station (NodeB) Two basic network elements, commonly known as the third generation (3G, 3rd Generation) communication network. In a Long-Term Evolution (LTE, Long Time Evolution) network, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) includes a basic network element called an evolved base station (eNB), commonly known as the fourth Generation (4G, 4th Generation) communication network. [0003] With the development of WCDMA netw...
