Dual Connectivity (DC) function. The DC function enables a single user equipment (UE) to perform wireless connection and uplink and downlink user services with two LTE serving base stations, namely, a primary Evolved Node B (MeNB) and a secondary Evolved Node B (SeNB). Transceiver transmission and transmission of data. The LTE/LTE-A system of the 3GPP standard specification introduces LTE and WLAN Aggregation (LWA) functions in the Rel-13 version, that is, the aggregation of radio resources in the radio access layer between the LTE system and the WLAN system. .

In the Rel-13 version, the system processing complexity is large. Currently, the LTE DC dual-connection operation and the LWA operation joint coexistence configuration of the UE cannot be supported. This causes the UE to be in the DC working mode at a moment. If the LTE network side wants to perform the LWA operation, it must first pass the The Radio Resource Control (RRC) control signaling enables the UE to exit the DC configuration first, and then causes the UE to enter the LWA configuration again through multiple RRC control signaling, and vice versa. The UE performs the conversion between different working modes of the DC and the LWA, and not only needs to consume a large amount of air interface signaling resources for reconfiguration; at the same time, the user plane DRBs data transmission of the UE also needs to be interrupted for a period of time; thus, the communication performance of the UE is degraded.

WLAN S-Link performs data transmission and the like.

The first DRB type that the primary base station creates or reconfigures for the user equipment is SCG Bearer. Then the MeNB allows only the SCG Bearer to be established, and does not offload to the WT2 or MeNB (the pure DC working mode in the Rel-12 version, already supported). After that, the primary base station needs to create or reconfigure a second DRB type for the same user equipment. The primary base station can learn which DRB types can be obtained according to the DRB type coexistence capability indication information, the RRM measurement report, and the RRM algorithm of the primary base station. Coexisting with SCG Bearer is configured. Specifically, if the UE indicates that the SCG Bearer can be coexistent with the MCG Bearer, the MeNB allows the configuration to be configured as the MCG Bearer for the second DRB type; or if the UE indicates that the SCG Bearer can be coexistent with the SCG Bearer, the MeNB is allowed to be the second. The strip DRB type selection is configured as SCG Bearer; or, if the UE indicates that the SCG Bearer can be coexistent with the Split Bearer, the MeNB allows the configuration to be configured as a Split Bearer for the second DRB type; or if the UE indicates that the SCG Bearer can be associated with the MCG side LWA If the Bearer coexistence is compatible, the MeNB allows the second DRB type to be configured as the MCG side LWA Bearer; or if the UE indicates that the SCG Bearer can be coexistent with the SCG side LWA Bearer, the MeNB allows the SCG to be configured as the SCG for the second DRB type. Side LWA Bearer et al.

If the first DRB type that the primary base station creates or reconfigures for the user equipment is the SCG side LWA Bearer, the MeNB allows only the SCG side LWA Bearer to be established, and only the WT2 is offloaded. After that, the primary base station needs to create or reconfigure a second DRB type for the same user equipment.

The MeNB allows only the Split Bearer to be established but does not offload to the WT1/WT2 (the pure DC working mode in the Rel-12 version is already supported). After that, the primary base station needs to create or reconfigure a second DRB type for the same user equipment. The primary base station can learn which DRB types can be obtained according to the DRB type coexistence capability indication information, the RRM measurement report, and the RRM algorithm of the primary base station. Coexistence with Split Bearer is configured. Specifically, if the UE indicates that the Split Bearer can be coexistent with the MCG Bearer, the MeNB allows the configuration to be configured as the MCG Bearer for the second DRB; or if the UE indicates that the Split Bearer can be coexistent with the SCG Bearer, the MeNB allows the second The DRB type selection is configured as SCG Bearer; or, if the UE indicates that the Split Bearer can be coexistent with the Split Bearer, the MeNB allows the configuration to be configured as a Split Bearer for the second DRB type; or, if the UE indicates that the Split Bearer can be associated with the MCG side LWA Bearer If the coexistence is compatible, the MeNB allows the second DRB type to be configured as the MCG side LWA Bearer; or if the UE indicates that the Split Bearer can be coexistent with the SCG side LWA Bearer, the MeNB allows the second DRB type to be configured as the SCG side. LWA Bearer et al.

The first DRB type newly created or reconfigured by the primary base station is a Split Bearer, and the MCG part in the Split Bearer is offloaded to the WT1. The MeNB allows only the Split Bearer to be established and the MCG part in the Split Bearer to be offloaded to the WT1.

The primary base station can learn which DRB types can be based on the DRB type coexistence capability indication information, the RRM measurement report, and the RRM algorithm of the primary base station. Split Bearer coexistence is configured. Specifically, if the UE indicates that the Split Bearer that is offloaded to the WT1 by the MCG part can be co-existed with the MCG Bearer, the MeNB is allowed to be configured as the MCG Bearer for the second DRB type; or, if the UE indicates that the MCG part is split to the WT1, the Split Bearer can Compatible with the SCG Bearer coexistence, the MeNB allows the second DRB type to be configured as the SCG Bearer; or if the UE indicates that the Split Bearer that the MCG part offloads to the WT1 can be coexistent with the Split Bearer, the MeNB allows the second DRB type.

Optionally, the system in all the embodiments of the present invention can always coexist with each other by default, that is, the MeNB selects one DRB type for the first DRB, and also allows configuration for the second DRB. The same type, so the UE does not need to do explicit coexistence capability Show to reduce the air interface capability signaling bit overhead. In addition, all the DRB type coexistence combinations enumerated above do not traverse the combination of all DRB types, and for future enhanced systems, there are more eNBs (not only MeNB/SeNB) and WTs (not only WT1/WT2). More scenarios and higher-dimensional multi-link/WLAN tight-coupling operations are handled in a manner consistent with the manner and implementation principles of the embodiments of the present invention.

When the UE needs to support configuring more concurrent service data flows, it may be configured by the MeNB to exceed two DRBs, and then the third and fourth...DRBs are established, and the MeNB needs to take the first and second DRBs as already Configure the DRB type and configure the third DRB type to be configured.
