The DC function enables a single User Equipment (UE) to simultaneously perform radio connection and uplink and downlink User traffic data transmission with two LTE serving base stations, namely, a Master Evolved Node B (MeNB) and a secondary base station (SeNB). In the LTE/LTE-a system specified by the 3GPP standard, an LTE and WLAN Aggregation (LWA) function is introduced in Rel-13, that is, aggregated use of radio resources is performed in a radio access layer between the LTE system and the WLAN system.
In Rel-13, the system processing complexity is large. Currently, LTE DC dual connectivity operation and LWA operation joint coexistence configuration of a UE cannot be supported, which may cause that when the UE is in a DC working mode at a certain time, if the UE enters an effective WLAN coverage area, an LTE network side wants to perform LWA operation, the UE must first exit the DC configuration through a plurality of Radio Resource Control (RRC) Control signaling, and then enter the LWA configuration through a plurality of RRC Control signaling, or vice versa.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
An embodiment of the present invention provides a method for acquiring a data radio bearer type, which is described with reference to fig. 1 and includes the following steps:
step 101, receiving a Radio Resource Management (RRM) measurement report sent by a user equipment.
Specifically, the step of receiving the RRM measurement report transmitted by the user equipment may be implemented by the master base station. The RRM measurement report may include: the coverage strength of the wireless pilot signal, the coverage quality of the wireless pilot signal, the signal-to-noise ratio received by the terminal, the load condition of the wireless link and the like.
And step 102, acquiring the RRM algorithm of the main base station.
Specifically, the step of acquiring the RRM algorithm of the master base station itself may be implemented by the master base station.
Step 103, setting a first Data Radio Bearer (DRB) type for the user according to the RRM measurement report and the RRM algorithm of the master base station itself.
Specifically, the step of setting the first DRB type for the user according to the RRM measurement report and the RRM algorithm of the master base station itself may be implemented by the master base station. The main base station can jointly determine the DRB type according to the specific situation of each parameter in the RRM measurement report and whether the RRM algorithm of the main base station can be realized, and set the first DRB type for the user. The first DRB may be a first DRB that is initiated by a core network Mobility Management Entity (MME) to a Radio Access Network (RAN) and may be used for uplink and downlink data transmission.
The method for acquiring the data radio bearer type in all embodiments of the present invention may be applied to a User Equipment (UE) in a DC working mode and/or an LWA working mode. The LTE DC mode of operation may provide three basic DRB types: a Master Cell group Bearer (MCG Bearer) for implementing uplink and downlink transmission of user service data through an MCG Link; a radio Bearer (Split Bearer) for simultaneously implementing uplink and downlink transmission of user service data via an MCG Link and a Secondary Cell group Link (SCG Link); secondary Cell group Bearer (SCG Bearer), which implements uplink and downlink data transmission of user service data through SCG Link. The LWA mode of operation may provide two basic DRB types (which may be collectively referred to as LWA bearer): the LWA Split Bearer simultaneously realizes uplink and downlink transmission of user service data through an LTE Link at an MeNB side and a WLAN Link air interface resource at a WLAN node (WT) side; the LWA handover Bearer (LWA Switched Bearer) realizes uplink and downlink transmission of user service data only through forwarding of the MeNB at the Xw-U interface and WLAN Link air interface resources at the WT side.
The method for acquiring the data radio bearer type provided by the embodiment of the invention can receive the RRM measurement report sent by the user equipment, acquire the RRM algorithm of the main base station, and then set the first DRB type for the user according to the RRM measurement report and the RRM algorithm of the main base station. Therefore, no matter the user is in the DC mode, the base station is suitable for the LWA mode or the LWA mode, the base station can easily set the DRB type for the user, so that the user can adopt the obtained DRB to carry out uplink and downlink transmission of service data, the problem that the data transmission in the DC mode and the data transmission in the LWA mode can not be coexisted in the prior art is solved, the waste of system resources is avoided, the communication performance and the user data service experience performance of the user are improved, and the experience effect of the user is enhanced. Meanwhile, the use efficiency of system resources is improved.
An embodiment of the present invention provides a method for acquiring a data radio bearer type, which is shown in fig. 2 and includes the following steps:
step 201, the main base station receives an RRM measurement report sent by the user equipment.
Step 202, the master base station acquires the RRM algorithm of the master base station itself.
And step 203, the main base station sets a first DRB type for the user according to the RRM measurement report and the RRM algorithm of the main base station.
And step 204, the main base station receives the DRB type coexistence capability indication information of the user equipment, which is sent by the user equipment.
Wherein, the DRB type coexistence capability indication information of the user equipment indicates a DRB type that can coexist with the DRB configured by the user equipment.
The DRB type coexistence capability indication information of the user equipment is the type of the DRB which is determined by the user equipment according to the protocol and can be compatible with the type of the DRB configured by the user equipment; the DRB type comprises at least one DRB type.
And step 205, the main base station sets other DRB types except the first DRB for the user equipment according to the DRB type coexistence capability indication information of the user equipment, the RRM measurement report and the RRM algorithm of the main base station.
Specifically, in the embodiment of the present invention, an example in which a main base station is used as a user equipment to create or configure two DRBs is described:
the first DRB type, newly created or reconfigured by the primary base station for the user equipment, is MCG Bearer and is not shunted to WT1 or SeNB (pure DC mode of operation in Rel-12 version, already supported). Then, the primary base station needs to newly establish or reconfigure a second DRB type for the same UE, and the primary base station can know which DRB types can be configured to coexist with the MCG Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the MCG Bearer can be compatible with the MCG Bearer coexistence, the MeNB allows to select a configuration as the MCG Bearer for the second DRB type; or if the UE indicates that the MCG Bearer is compatible with the SCG Bearer coexistence, the MeNB allows to select a configuration as SCG Bearer for the second DRB type; or if the UE indicates that the MCG Bearer is compatible with Split Bearer coexistence, the MeNB allows to select a configuration as Split Bearer for the second DRB type; or if the UE indicates that the MCG Bearer is compatible with the MCG-side LWA Bearer coexistence, the MeNB allows to select a configuration as the MCG-side LWA Bearer for the second DRB type; or if the UE indicates that the MCG Bearer is compatible with the SCG-side LWA Bearer coexistence, the MeNB allows to choose a configuration as SCG-side LWA Bearer for the second DRB type, etc.
The first DRB type newly created or reconfigured by the primary base station for the user equipment is the MCG-side LWA Bearer, and the MeNB allows offloading only to WT1 (pure LWA mode of operation in Rel-13, already supported). Then, the primary base station needs to newly establish or reconfigure a second DRB type for the same UE, and the primary base station can know which DRB types can be configured to coexist with the LWA Bearer on the MCG side according to the DRB type coexistence capability indication information, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the LWA Bearer on the MCG side can be compatible with the MCG Bearer coexistence, the MeNB allows to select and configure the LWA Bearer as the MCG Bearer for the second DRB type; or, if the UE indicates that the MCG-side LWA Bearer is compatible with SCG Bearer coexistence, the MeNB allows to select a configuration as SCG Bearer for the second DRB type; or, if the UE indicates that the MCG-side LWA Bearer is compatible with Split Bearer coexistence, the MeNB allows to select a configuration as Split Bearer for the second DRB type; or if the UE indicates that the MCG side LWA Bearer can be compatible with the MCG side LWA Bearer coexistence, the MeNB allows to select a configuration as the MCG side LWA Bearer for the second DRB type, wherein the MCG side LWA Bearer performs data transmission through the WLAN P-Link; or, if the UE indicates that the MCG side LWA Bearer can be compatible with the SCG side LWA Bearer in coexistence, the MeNB allows to select a configuration as the SCG side LWA Bearer for the second DRB type, where the MCG side LWA Bearer performs data transmission through the WLAN P-Link, the SCG side LWA Bearer performs data transmission through the WLAN S-Link, and so on.
The first DRB type newly created or reconfigured by the primary base station for the ue is SCG Bearer, then the MeNB allows only SCG Bearer to be established without offloading to WT2 or the MeNB (pure DC operating mode in Rel-12 version, already supported). Then, the primary base station needs to newly build or reconfigure a second DRB type for the same UE, and the primary base station can know which DRB types can be configured to coexist with the SCG Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the SCG Bearer can be compatible with the MCG Bearer coexistence, the MeNB allows to select the configuration as the MCG Bearer for the second DRB type; or, if the UE indicates that the SCG Bearer is compatible with SCG Bearer coexistence, the MeNB allows to select a configuration as SCG Bearer for the second DRB type; or, if the UE indicates that the SCG Bearer is compatible with Split Bearer coexistence, the MeNB allows to select a configuration as Split Bearer for the second DRB type; or, if the UE indicates that the SCG Bearer is compatible with the MCG-side LWA Bearer coexistence, the MeNB allows to select a configuration as the MCG-side LWA Bearer for the second DRB type; alternatively, if the UE indicates that the SCG Bearer can be compatible with the SCG-side LWA Bearer coexistence, the MeNB allows to choose a configuration as SCG-side LWA Bearer, etc. for the second DRB type.
The first DRB type newly created or reconfigured by the primary base station for the user equipment is the SCG-side LWA Bearer, and the MeNB allows only the SCG-side LWA Bearer to be established and only shunted to the WT 2. Then, the primary base station needs to newly build or reconfigure a second DRB type for the same UE, and the primary base station can know which DRB types can be configured to coexist with the SCG-side LWA Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the SCG side LWA Bearer can be compatible with the MCG Bearer coexistence, the MeNB allows to select and configure the second DRB type as the MCG Bearer; or, if the UE indicates that the SCG-side LWA Bearer is compatible with SCG Bearer coexistence, the MeNB allows to select a configuration as SCG Bearer for the second DRB type; or, if the UE indicates that the SCG-side LWA Bearer can be compatible with Split Bearer coexistence, the MeNB allows to select a configuration as Split Bearer for the second DRB type; or if the UE indicates that the SCG side LWA Bearer can be compatible with the MCG side LWA Bearer in coexistence, the MeNB allows to select and configure the second DRB type as the MCG side LWA Bearer, wherein the SCG side LWA Bearer performs data transmission through the WLAN S-Link, and the MCG side LWA Bearer performs data transmission through the WLAN P-Link; or, if the UE indicates that the SCG-side LWA Bearer can be compatible with the SCG-side LWA Bearer coexistence, the MeNB allows to select the configuration as the SCG-side LWA Bearer for the second DRB type, wherein the SCG-side LWA Bearer performs data transmission through the WLAN S-Link, and the like.
The first DRB type newly created or reconfigured by the primary base station for the user equipment is Split Bearer, then MeNB allows only Split Bearer to be established, but not shunted to WT1/WT2 (pure DC mode of operation in Rel-12 version, already supported). Then, the primary base station needs to newly establish or reconfigure a second DRB type for the same UE, and the primary base station can know which DRB types can be configured for coexistence with the Split Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the Split Bearer is compatible with the MCG Bearer coexistence, the MeNB allows to select the configuration as the MCG Bearer for the second DRB; or, if the UE indicates that Split Bearer is compatible with SCG Bearer coexistence, the MeNB allows to select configuration as SCG Bearer for the second DRB type; alternatively, if the UE indicates that Split Bearer is compatible with Split Bearer coexistence, the MeNB allows to select the configuration as Split Bearer for the second DRB type; or, if the UE indicates that the Split Bearer is compatible with the MCG-side LWA Bearer coexistence, the MeNB allows to select a configuration as the MCG-side LWA Bearer for the second DRB type; alternatively, if the UE indicates that Split Bearer can be compatible with SCG side LWA Bearer coexistence, the MeNB allows to choose a configuration as SCG side LWA Bearer etc. for the second DRB type.
The first DRB type newly created or reconfigured by the primary base station for the user equipment is Split bear, and the MCG part in the Split bear is shunted to WT1, then the MeNB allows only the Split bear to be established and shunted to WT 1. Then, the primary base station needs to newly build or reconfigure a second DRB for the same UE, and the primary base station can know which DRB types can be configured for coexistence with the Split Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the Split Bearer shunted by the MCG part to WT1 can be compatible with MCG Bearer coexistence, the MeNB allows to select configuration as MCG Bearer for the second DRB type; alternatively, if the UE indicates that the Split Bearer that the MCG part shunts to WT1 may be compatible with SCG Bearer coexistence, the MeNB allows to select configuration as SCG Bearer for the second DRB type; alternatively, if the UE indicates that the Split Bearer that the MCG part shunts to WT1 may be compatible with Split Bearer coexistence, the MeNB allows the configuration to be selected as Split Bearer for the second DRB type; or, if the UE indicates that the Split Bearer shunted by the MCG part to the WT1 can be compatible with the MCG side LWA Bearer coexistence, the MeNB allows to select the configuration as the MCG side LWA Bearer for the second DRB type; alternatively, if the UE indicates that the Split Bearer that the MCG part shunts to the WT1 can be compatible with SCG-side LWA Bearer coexistence, the MeNB allows to choose the configuration as SCG-side LWA Bearer, etc. for the second DRB type. The Split Bearer which shunts the MCG part to the WT1 carries out data transmission through the WLAN P-Link, and the LWA Bearer on the SCG side carries out data transmission through the WLAN S-Link.
The first DRB type newly created or reconfigured by the primary base station for the user equipment is Split bear, and the SCG part in the Split bear is shunted to WT2, then the MeNB allows only the Split bear to be established and shunted to WT 2. Then, the primary base station needs to newly build or reconfigure a second DRB for the same UE, and the primary base station can know which DRB types can be configured for coexistence with the Split Bearer according to the DRB type coexistence capability indication information of the UE, the RRM measurement report, the first input parameter, and the RRM algorithm of the primary base station itself. The method comprises the following specific steps: if the UE indicates that the Split Bearer shunted by the SCG part to WT2 is compatible with MCG Bearer coexistence, the MeNB allows to select configuration as MCG Bearer for the second DRB type; alternatively, if the UE indicates that the Split Bearer that SCG part shunts to WT2 may be compatible with SCG Bearer coexistence, the MeNB allows to choose the configuration as SCG Bearer for the second DRB type; alternatively, if the UE indicates that the Split Bearer that SCG part shunts to WT2 may be compatible with Split Bearer coexistence, the MeNB allows the configuration to be selected as Split Bearer for the second DRB type; or, if the UE indicates that the Split Bearer of the SCG part to the WT2 can be compatible with the MCG side LWA Bearer coexistence, the MeNB allows to select the configuration as the MCG side LWA Bearer for the second DRB type, wherein the Split Bearer of the SCG part to the WT2 performs data transmission through the WLAN S-Link, and the MCG side LWA Bearer performs data transmission through the WLAN P-Link; alternatively, if the UE indicates that the Split Bearer of SCG part towards WT2 can be compatible with SCG side LWA Bearer coexistence, the MeNB allows to choose the configuration as SCG side LWA Bearer etc. for the second DRB type. Wherein, the Split Bearer and the MCG side LWA Bearer which shunt the SCG part to the WT2 carry out data transmission through the WLAN S-Link.
And step 206, in the double-connection DC and/or long-term evolution and wireless local area network aggregation LWA mode, the main base station carries out uplink and downlink transmission of user service data through the DRB.
Specifically, the systems in all embodiments of the present invention may default that the same DRB type may always coexist with each other, i.e.: the MeNB selects and configures a certain DRB type for the first DRB, and then allows the same type to be configured for the second DRB, so the UE does not need to make an explicit coexistence capability indication any more, so as to reduce the overhead of the air interface capability signaling bits. In addition, the coexistence combination of all DRB types enumerated above does not traverse the combination situation of all DRB types, and for the scenario that more eNBs (not only MeNB/SeNB) and WTs (not only WT1/WT2) perform multi-link/WLAN tight coupling operation with more connection numbers and higher dimensions in the future enhanced system, the processing method is consistent with the method and implementation principle of the present invention.
When the UE needs to support configuration of more concurrent service data streams, more than two DRBs may be configured by the MeNB, and then a third and a fourth … DRBs are established, so that the MeNB needs to take the first and the second DRBs as configured DRB types and perform configuration constraint on the third to-be-configured DRB type; and by analogy, any newly-established DRB type is compatible with all DRBs configuration coexistence types indicated by the UE capability, and cannot exceed the DRB type coexistence capability range of the UE.

At this time, the MeNB obtains, according to the DRB type coexistence capability reported by the UE and the RRM Measurement Report reported by the UE through the Measurement Report message in the Radio Resource Control (RRC): the UE is currently under good signal coverage of the target MCG serving cell, the target SCG serving cell and the target SCG-side WT2/AP, and furthermore, the MeNB knows that the target MCG/SCG serving cell has almost the same load at the moment through the X2 interface interaction message, and knows that the target SCG-side WT2/AP has relatively light load at the moment through the Xw + X2 interface interaction message, so it is determined that the DRB (1) type is LWA Bearer of the SCG side (which may be specifically configured as LWA Switched Bearer); the user then initiates VOLTE voice traffic and the serving MeNB needs to establish/reconfigure a second DRB (2) for the UE. Assuming that the network signal coverage/serving node load state where the UE is located does not change, according to the DRB type coexistence capability reported by the UE, the MeNB may select the configured types for the DRB (2) as follows: and any one of MCG Bearer, SCG Bearer and SCG side LWA Bearer, wherein the type of the DRB (2) is finally determined to be MCG Bearer by the MeNB in combination with the input condition of the RRM algorithm of the main base station.
