Description

Data processing method, device and system

Technical Field

The present invention relates to communications technologies, and in particular, to a data processing method, apparatus, and system.

Background

With the development of the mobile internet, the demand of end users for bandwidth is higher and higher, and in order to improve the throughput of the network, a plurality of small sites may be introduced into a cell of a macro network to form a small cell, and the small cell may be placed in a service hot spot area or a load hole area. In this way, when User Equipment (UE for short) moves from the macro cell to these areas, the service of the UE may be switched into these small cells, so as to implement traffic offloading or make up for coverage. When the UE moves from the small cell to the macro cell, the service of the UE is switched to the middle cell, and the base station of the macro cell provides service.

However, each time the UE moves between the macro cell and the small cell, handover occurs, which causes a problem of increasing the number of handovers, and each handover procedure also needs to introduce a large amount of handover-related signaling. In addition, in the heterogeneous network (het net), when the UE moves to the coverage of the small cell, the UE switches to the small cell and disconnects from the macro cell, but since the small cell has only one Frequency, when the UE uses one Radio Frequency (RF) to communicate with the small cell on the Frequency, and the macro cell has idle resources, the UE cannot communicate with the macro cell, and therefore, the idle resources cannot be utilized to improve the throughput of the UE.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart of an embodiment of a data processing method of the present invention, and as shown in fig. 1, this embodiment describes a method for processing first uplink information by using a base station as an execution subject, and specifically includes the following steps:

step 100, a base station establishes Radio Resource Control (RRC) connection with a User Equipment (User Equipment, abbreviated to UE), and respectively establishes a mapping relationship between a first logical channel identifier corresponding to a Control layer Radio Bearer (SRB) of the UE and the base station, and/or a mapping relationship between a second logical channel identifier corresponding to a Data Radio Bearer (DRB) of all or part of the UE and a wireless communication node.

In this embodiment, the base station respectively establishes the mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station, and/or the mapping relationship between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node, which may be as follows:

the first condition is as follows: the base station respectively establishes a mapping relation between a first logical channel identifier corresponding to the SRB of the UE and the base station and a mapping relation between a second logical channel identifier corresponding to all or part of the DRB of the UE and the wireless communication node.

Case two: and the base station establishes a mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station.

It should be noted that the mapping relationship between the second logical channel identifier corresponding to all or part of the DRB of the UE and the wireless communication node may be established by the wireless communication node, and details will be specifically described in an embodiment in which the wireless communication node is an execution main body, and details are not described here.

Case three: and the base station establishes a mapping relation between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node.

Specifically, when the wireless communication node is set to be in a default condition, that is, when the received second uplink information sent by the UE is transmitted to the wireless communication node through the SRB, the second uplink information is forwarded to the base station, and at this time, the base station does not need to establish a mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station. The second uplink information is uplink information sent by the UE to the wireless communication node.

It should be noted that a Data transmission service provided by a Packet Data Convergence Protocol (PDCP) is called a Radio Bearer (RB), and the RB may include an SRB and a DRB, where the SRB is used for carrying RRC signaling and the DRB is used for carrying user Data. The RBs and the logical channel identifiers are in a one-to-one correspondence relationship, that is, one RB corresponds to only one logical channel identifier, specifically, one SRB corresponds to one first logical channel identifier, one DRB corresponds to one second logical channel identifier, and the first logical channel identifier is different from the second logical channel identifier.

Step 101, a base station receives first uplink information sent by UE.

Specifically, the first uplink information may be transmitted through an SRB or a DRB.

Step 102, if the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, the base station forwards the first uplink information to the wireless communication node corresponding to the logical channel identifier included in the first uplink information.

Specifically, the base station determines the received first uplink information, and if a logical channel identifier included in the first uplink information exists in a mapping relationship between the second logical channel identifier and the corresponding wireless communication node, that is, it indicates that the first uplink information is transmitted through the DRB, the first uplink information needs to be correspondingly processed by the wireless communication node, and the base station forwards the first uplink information to the corresponding wireless communication node. After receiving the first uplink information, the wireless communication node performs corresponding processing on the first uplink information, for example, performs conventional processing such as filtering processing and service access on the first uplink information.

It should be noted that the base station corresponds to one macro cell, and the wireless communication node corresponds to one small cell.

In this embodiment, the determining whether the logical channel identifier included in the first uplink information has a function in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node may be implemented by an MAC protocol entity.

In addition, it should be noted that, if the logical channel identifier that is exchanged by the first uplink information packet exists in the mapping relationship between the first logical channel identifier and the corresponding wireless communication node, that is, it is described that the first uplink information is transmitted through the SRB, the base station needs to perform corresponding processing on the first uplink information, for example, the base station performs corresponding processing on the first uplink information by: after receiving the first uplink information, sending a response message to the UE; or, performing conventional processing on the first uplink information, such as filtering processing, service access, and the like.

In the data processing method provided by this embodiment, a radio resource control protocol RRC connection is established between a base station and a user equipment UE, and a mapping relationship between a first logical channel identifier corresponding to an SRB of the UE and the base station and/or a mapping relationship between a second logical channel identifier corresponding to all or part of a DRB of the UE and a wireless communication node are respectively established, so that the base station can accurately determine that received first uplink information sent by the UE is transmitted through the SRB or the DRB according to the mapping relationship between different logical channel identifiers and the base station or the wireless communication node, and if the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, the base station forwards the first uplink information to the wireless communication node corresponding to the logical channel identifier. If the logical channel identifier corresponding to the SRB exists in the mapping relationship between the first logical channel identifier and the base station, the base station can process the first uplink information, thereby implementing a function of processing the first uplink information transmitted through the SRB by the base station, and processing all or part of the first uplink information transmitted through the DRB by the wireless communication node.

Further, in another embodiment of the present invention, on the basis of the embodiment shown in fig. 1, a specific implementation manner in step 102 is as follows:

and if the logical channel identifier contained in the first uplink information is in the mapping relation between the second logical channel identifier and the corresponding wireless communication node, the base station generates a first forwarding data packet, wherein the first forwarding data packet contains the first uplink information, and sends the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier contained in the first uplink information. .

Specifically, the base station sends the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier, and the method can be implemented in two ways, namely: the identifier of the UE is added to the first forwarding data packet and sent through the established tunnel, so that the wireless communication node can determine which UE the first forwarding data packet belongs to according to the identifier of the UE, for example, the identifier of the UE may be a UE id, it should be noted that the established tunnel is a tunnel that is uniformly established by the base station for each UE thereof, that is, different UEs correspond to one tunnel. The second method comprises the following steps: and sending the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier contained in the first uplink information through the previously established tunnel specific to the UE, so that the wireless communication node can also determine which UE the first forwarding data packet belongs to according to the specific tunnel. It should be noted that the UE-specific tunnel is a tunnel that is set by the base station for each UE individually, and the UE is different and the corresponding tunnel is also different. In the above two methods, the base station sets a tunnel after step 100.

Fig. 2 is a flowchart of another embodiment of the data processing method of the present invention, based on the above-mentioned embodiment shown in fig. 1, as shown in fig. 2, after step 100, the method further includes:

step 103, the base station sends an indication message to the wireless communication node.

Specifically, when the base station establishes a mapping relationship between a first logical channel identifier corresponding to the SRB of the UE and the base station and a mapping relationship between a second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node, respectively, the indication message includes the mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relationship between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node. When the base station establishes the mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station, the indication message includes the mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station. When the base station establishes the mapping relationship between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node, the indication message includes the mapping relationship between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the corresponding wireless communication node.

In this embodiment, after the wireless communication node receives the indication message sent by the base station, the wireless communication node may obtain, according to the indication message, the mapping relationship between the SRB and the base station, the DRB and the wireless communication node, or the mapping relationship between the SRB and the base station, and another DRB and the wireless communication node, so that when the wireless communication node receives the second uplink information sent by the UE or the first uplink information forwarded by the base station, the wireless communication node may process the second uplink information or the forwarded first uplink information by determining whether the second uplink information or the forwarded first uplink information is transmitted through the SRB or the DRB, or forward the second uplink information to the base station according to the logical channel identifier and the mapping relationship of the SRB or the DRB included in the second uplink information or the forwarded first uplink information, so as to implement that the first uplink information transmitted through the SRB or the second uplink information transmitted through the SRB is processed by the base station, and the first uplink information transmitted by all or part of the DRBs or the second uplink information transmitted by all or part of the DRBs is processed by the wireless communication node, so that the problem of poor mobility of the UE during roaming caused by processing all the SRBs and the DRBs on the wireless communication node in the prior art is solved, and the utilization rate of idle resources of the base station is effectively improved.

Preferably, in step 100, when the base station establishes a mapping relationship between the second logical channel identifier corresponding to the partial DRB of the UE and the corresponding wireless communication node, the method further includes:

the base station establishes Radio Resource Control (RRC) connection with the UE, and establishes a mapping relation between a third logical channel identifier corresponding to other DRBs of the UE except for a part of the DRBs and the base station.

After a base station receives first uplink information sent by a UE, the base station determines the first uplink information, and if a logical channel identifier included in the first uplink information exists in a mapping relationship between a third logical channel identifier corresponding to a DRB other than a part of DRBs of the UE and the base station, it indicates that the first uplink information is transmitted through the DRB, and the first uplink information transmitted through the DRB needs to be processed by the base station, the base station performs corresponding processing on the first uplink information, and the base station performs corresponding processing on the first uplink information: after receiving the first uplink information, sending a response message to the UE; or, performing conventional processing on the first uplink information, such as filtering processing, service access, and the like.

Further, in this embodiment, when the base station establishes a mapping relationship between the third logical channel identifier corresponding to the DRB of the UE except for the partial DRB and the base station, the indication message sent by the base station to the wireless communication node may further include: and mapping relation between the third logical channel identifier corresponding to other DRBs except for part of DRBs of the UE and the base station.

More preferably, the base station may further receive second uplink information or a second forwarding data packet sent by the wireless communication node. Specifically, after the wireless communication node receives the second uplink information sent by the UE, if a logical channel identifier included in the second uplink information exists in a mapping relationship between the first logical channel identifier and the base station, it indicates that the second uplink information is transmitted through the SRB and needs to be processed by the base station, the second uplink information is forwarded to the base station corresponding to the logical channel identifier, and optionally, a second forwarding packet including the second uplink information is generated, and the second forwarding packet is forwarded to the base station corresponding to the logical channel identifier.

It should be noted that the second uplink information may be transmitted to the wireless communication node through the SRB, or may be transmitted to the wireless communication node through the DRB. When the second uplink information is transmitted through the DRB, the logical channel identifier of the DRB exists in the mapping relationship between the third logical channel identifier and the base station, which indicates that the second uplink information needs to be processed through the base station, and then the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier.

Optionally, the wireless communication node generates a second forwarding data packet including the second uplink information, and sends the second forwarding data packet to the base station corresponding to the logical channel identifier. The scheme is suitable for the condition that the base station has idle resources, and can process a part of user data transmitted by the DRB, thereby not only reducing the workload of the wireless communication node, but also effectively utilizing the idle resources of the base station. When the base station receives the second forwarding data packet, the base station may perform corresponding processing on the second forwarding data packet, for example, perform conventional processing such as filtering processing and service access on the second uplink information in the second forwarding data packet.

In this embodiment, for example, when the UE is handed over to a different wireless communication node, the UE performs first uplink information transmitted to the base station through the SRB or second uplink information transmitted to the wireless communication node through the SRB, and a part of the first uplink information transmitted to the base station through the DRB or a part of the second uplink information transmitted to the wireless communication node through the DRB, and the base station or the wireless communication node determines each of the uplink information: if the wireless communication node judges that the logical channel identifier of the received second uplink information exists in the mapping relation with the base station, the second uplink information is forwarded to the base station for processing; if the base station judges that the logical channel mark of the received first uplink information exists in the mapping relation with the wireless communication node, the first uplink information is forwarded to the wireless communication node for processing, so that the uplink information transmitted through the SRB is not switched among different wireless communication nodes along with the switching of the UE, the switching times of the uplink information transmitted through the SRB or the DRB are reduced, and the first uplink information or the second uplink information transmitted through the DRB can be processed by the base station through a part of the uplink information transmitted through the DRB, namely, the base station establishes the mapping relation between the third logical channel mark corresponding to other DRBs except the part of the DRBs of the UE and the base station, so that the idle resources of the base station are effectively utilized.

Further, in another embodiment of the present invention, on the basis of the embodiment shown in fig. 1 or fig. 2, after the base station establishes the radio resource control protocol RRC connection with the UE, before step 101, the method further includes the following steps:

a base station receives a first uplink transmission request message sent by UE, and sends a first uplink information permission message carrying bandwidth resource information to the UE according to the first uplink transmission request message; the bandwidth resource information is used for the UE to adapt resources for the first uplink information sent to the base station according to the bandwidth resource information.

Specifically, before the UE sends the first uplink information to the base station, it first needs to send a first uplink transmission Request message to the base station, where the first uplink transmission Request message may be a Scheduling Request (SR). Preferably, in the standard Release11, on the basis that a Physical Uplink Control Channel (PUCCH) of the UE originally uses the same frequency as that of the base station for transmission, the UE further has another PUCCH, and the PUCCH uses the same frequency as that of the wireless communication node, so that the UE can randomly transmit an Uplink transmission request message to the base station or the wireless communication node through the two PUCCHs. It should be noted that the uplink transmission request message sent by the UE to the base station may be referred to as a first uplink transmission request message.

In addition, for a UE having one PUCCH in the existing standard Release10, the UE only sends an uplink transmission request message (i.e., the first uplink transmission request message) to the base station. In the embodiment of the invention, the wireless communication node is additionally provided with a Radio Frequency (RF) with a monitoring function, the RF adopts the same Frequency of PUCCH transmitted by UE and a base station, and the purpose of the RF is to monitor HARQ feedback information sent by the UE in the downlink information transmission process. However, it should be noted that, in the uplink information transmission, when the UE only sends the first uplink transmission request message to the base station, in order to avoid the wireless communication node with the monitoring function from monitoring the first uplink transmission request message and the first uplink information, the wireless communication node needs to be set not to respond to the uplink transmission request message of the UE, and therefore, after the base station receives the first uplink transmission request message sent by the UE in step 101, the method further includes:

and the base station sends an uplink transmission indication message to the wireless communication node so that the wireless communication node does not respond to the received first uplink transmission request message according to the uplink transmission indication message.

Fig. 3 is a flowchart of a data processing method according to another embodiment of the present invention, based on the example shown in fig. 2, as shown in fig. 3, when the UE detects the base station and the wireless communication node at the same time, it is generally assumed that the UE is closer to the wireless communication node by default, at this time, in order to reduce power consumption of uplink information transmission performed by the UE, the UE needs to preferentially perform uplink information transmission with the wireless communication node, and the base station does not respond to the first uplink transmission request message sent by the UE, and after receiving the first uplink information sent by the UE, the base station further includes the following steps:

and step 104, the base station does not respond to the received first uplink transmission request message sent by the UE and waits for receiving a second forwarding data packet sent by the wireless communication node.

Fig. 4 is a flowchart of a data processing method according to another embodiment of the present invention, and as shown in fig. 4, the present embodiment is described with a wireless communication node as an execution subject, and specifically includes the following steps:

step 200, the wireless communication node obtains the mapping relationship between the second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or the mapping relationship between the first logical channel identifier corresponding to SRBs of the UE and the base station.

Specifically, before the UE performs uplink information transmission through the wireless communication node, the wireless communication node first obtains a mapping relationship between a second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or a mapping relationship between a first logical channel identifier corresponding to SRBs of the UE and the base station.

Step 201, the wireless communication node receives the second uplink information sent by the UE.

Step 202, if the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier included in the second uplink information.

Specifically, after receiving the second uplink information sent by the UE, the wireless communication node performs a determination according to a logical channel identifier included in the second uplink information, and if the logical channel identifier included in the second uplink information exists in a mapping relationship between the first logical channel identifier and the base station, that is, the second uplink information is transmitted through the SRB, the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier. If the logical channel identifier included in the second uplink information exists in the mapping relationship between the second logical channel identifier and the wireless communication node, that is, the second uplink information is transmitted through the DRB, the wireless communication node performs corresponding processing on the second uplink information, for example, performing conventional processing such as filtering processing and service access on the second uplink information.

In the data processing method provided in this embodiment, the wireless communication node obtains a mapping relationship between a second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or a mapping relationship between a first logical channel identifier corresponding to an SRB of the UE and the base station, so that the wireless communication node can accurately determine that the received second uplink information sent by the UE is transmitted through the SRB or the DRB according to the mapping relationship between different logical channel identifiers and the base station or the wireless communication node, and if the logical channel identifier included in the second uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, that is, the second uplink information is transmitted through the DRB, the wireless communication node correspondingly processes the second uplink information. If the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, that is, the second uplink information is transmitted through the SRB, the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier. The uplink information transmitted by the SRB is processed by the base station, and the uplink information transmitted by all or part of the DRB is processed by the wireless communication node, so that when the UE moves to other wireless communication nodes, the first uplink information transmitted by the SRB or the second uplink information transmitted by the SRB is always processed by the base station, the problem that the SRB and the DRB are frequently switched due to the fact that the UE moves to other wireless communication nodes is solved, the switching times of the SRB and the DRB are reduced, the moving performance of the UE is improved, the utilization rate of idle resources of the base station is effectively improved, and the load pressure of the wireless communication node is reduced.

Further, in another embodiment of the present invention, based on the embodiment shown in fig. 4, a specific implementation manner in step 202 is as follows:

if the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, the wireless communication node generates a second forwarding data packet, where the second forwarding data packet includes the second uplink information, and sends the second forwarding data packet to the base station, so that the base station can perform corresponding processing on the second forwarding data packet, for example, performing conventional processing such as filtering processing, service access, and the like on the second uplink information.

Specifically, if the wireless communication node determines that the logical channel identifier exists in the mapping relationship between the first logical channel identifier and the base station according to the logical channel identifier included in the second uplink information, the second uplink information is transmitted through the SRB, at this time, the wireless communication node generates a second forwarding data packet, and the second forwarding data packet includes the second uplink information and sends the second forwarding data packet to the base station, so that the base station can correspondingly process the second forwarding data packet.

In addition, preferably, the step 200 can have the following specific implementation manners:

the wireless communication node receives an indication message sent by a base station; the indication message contains a mapping relation between a first logical channel identifier corresponding to the SRB of the UE and the base station; and establishing a mapping relation between a second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node. Or,

the wireless communication node receives an indication message sent by a base station; the indication message contains the mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relation between the second logical channel identifier corresponding to all or part of the DRB of the UE and the wireless communication node. Or,

the wireless communication node receives an indication message sent by a base station; the indication message contains mapping relations between second logical channel identifications corresponding to all DRBs of the UE and the wireless communication nodes; and establishing a mapping relation between a first logical channel identifier corresponding to the SRB of the UE and the base station. Or,

the wireless communication node receives an indication message sent by a base station; the indication message comprises a mapping relation between a second logic channel identifier corresponding to part of DRBs of the UE and the wireless communication node; and respectively establishing a mapping relation between a first logical channel identifier corresponding to the SRB of the UE and the base station and a mapping relation between a third logical channel identifier corresponding to other DRBs except for part of the DRBs and the base station. Or,

the wireless communication node receives an indication message sent by a base station; the indication message includes a mapping relationship between a first logical channel identifier corresponding to the SRB of the E of the UE and the base station, and a mapping relationship between a second logical channel identifier corresponding to the partial DRB and the wireless communication node.

In this embodiment, when there are more idle network resources in the base station, a part of the wireless communication node may transmit the second uplink information to the base station through the DRB for processing, and after the base station establishes the mapping relationship between the third logical channel identifier corresponding to the DRB of the UE except the part of the DRB and the base station, the wireless communication node obtains the mapping relationship between the third logical channel identifier corresponding to the DRB except the part of the DRB and the base station through the above manner.

More preferably, after the wireless communication node acquires the mapping relationship between the third logical channel identifier and the base station corresponding to the DRBs of the UE except for the partial DRBs, a specific implementation manner of step 202 is as follows: and if the logical channel identifier contained in the second uplink information exists in the mapping relation between the first logical channel identifier and the base station or the logical channel identifier contained in the second uplink information exists in the mapping relation between the third logical channel identifier and the base station, the wireless communication node generates a second forwarding data packet, wherein the second forwarding data packet contains the second uplink information and sends the second forwarding data packet to the base station so that the base station can correspondingly process the second forwarding data packet.

In this embodiment, after the UE sends the second uplink information to the wireless communication node, the wireless communication node performs a determination according to the logical channel identifier included in the received second uplink information, and if the logical channel identifier included in the second uplink information exists in a mapping relationship between the third logical channel identifier and the base station, that is, if the second uplink information is transmitted through the DRB, it needs to switch to the base station for subsequent processing, which specifically is: the wireless communication node generates a second forwarding data packet and transmits the second forwarding data packet to the base station. The second forwarding data packet includes the second uplink information. This allows efficient use of idle network resources of the base station and provides mobility when the UE moves to other wireless communication nodes, reducing the number of handovers of SRBs and DRBs due to UE movement.

Further, in another embodiment of the present invention, on the basis of the embodiment shown in fig. 4, before the step 201, the wireless communication node receives the second uplink information sent by the UE, the method further includes:

and the wireless communication node receives a second uplink transmission request message sent by the UE and sends a second uplink information permission message carrying broadband resource information to the UE according to the second uplink transmission request message, wherein the bandwidth resource information is used for the UE to adapt resources for the second uplink information transmitted to the wireless communication node according to the bandwidth resource information.

Preferably, in the standard RELEASE11, on the basis that one PUCCH originally used by the UE transmits on the same frequency as the base station, the UE may have another PUCCH, which uses the same frequency as the wireless communication node, so that the UE may transmit the uplink transmission request message, i.e., the second uplink transmission request message, to the wireless communication node through the two PUCCHs when the UE transmits the uplink transmission request message to the base station or the wireless communication node, respectively.

More preferably, the method may further include:

the wireless communication node receives a first forwarding data packet sent by the base station and correspondingly processes the first forwarding data packet, wherein the first forwarding data packet is a data packet generated by the base station according to the received first uplink information sent by the UE.

Specifically, referring to step 102 in fig. 1, when the first uplink information received by the base station is transmitted through the DRB, and the second logical channel identifier corresponding to the DRB and the wireless communication node have a mapping relationship, the base station forwards the first uplink information to the wireless communication node. Optionally, the forwarding may be implemented by forwarding a first forwarding data packet including first uplink information, and after receiving the first forwarding data, the wireless communication node determines whether a logical channel identifier included in the first uplink information exists in a mapping relationship between a second logical channel identifier and the wireless communication node, and if so, the wireless communication node correspondingly processes the first uplink information transmitted by the DRB.

More preferably, in a scenario that the UE only has one PUCCH and can only perform transmission of the first uplink information with the base station, step 201, the receiving, by the wireless communication node, the second uplink information sent by the UE specifically includes:

and the wireless communication node monitors the UE and receives second uplink information sent by the UE. It should be noted that the second uplink information is first uplink information that the UE sends to the base station.

Specifically, when the UE sends the first uplink information to the base station through only one PUCCH, and the distance between the UE and the wireless communication node is closer to the base station than the distance between the UE and the base station, at this time, in order to reduce power consumption of uplink information transmission performed by the UE, the base station needs to be set not to respond to the first uplink transmission request message sent by the UE, specifically, the setting may be performed through the base station, or may be performed through an Operation and Administration (OAM) system of the base station, and after the base station receives the first uplink transmission request message sent by the UE, the first uplink transmission request message is discarded. At this time, the wireless communication node adds an RF with the same frequency as the base station to monitor the first uplink information sent by the UE to the base station, so as to obtain the second uplink information. It should be noted that the second uplink information is the first uplink information that the UE sends to the base station.

Fig. 5 is a flowchart of a further embodiment of the data processing method of the present invention, based on the embodiment shown in fig. 4, as shown in fig. 5, on the basis that one original PUCCH of the UE and the base station transmit at the same frequency, the UE further has a PUCCH at the same frequency as the radio communication node, the UE has a function of sending a first uplink transmission request message to the base station or the radio communication node through the two PUCCHs, and in order to determine whether the uplink information sent by the UE is transmitted through the SRB or the DRB through the base station, and further determine whether the uplink information is processed by the base station or is forwarded to the radio communication node, at this time, the radio communication node needs to be set not to respond to the first uplink transmission request message sent by the UE, and further, after step 200, the method further includes the following steps:

step 203, the wireless communication node receives an uplink transmission indication message sent by the base station.

And step 204, the wireless communication node does not respond to the monitored second uplink transmission request message sent by the UE according to the uplink transmission indication message.

Fig. 6 is a flowchart of a data processing method according to still another embodiment of the present invention, and on the basis of the embodiment shown in fig. 4, as shown in fig. 6, when performing downlink information transmission, after step 200, the method further includes the following steps:

step 205, the wireless communication node sends downlink information to the UE and monitors that the UE sends an HARQ feedback message.

Specifically, after the wireless communication node sends downlink information to the UE, the UE sends HARQ feedback information after receiving the downlink information, and for the UE which does not add a new PUCCH to communicate with the wireless communication node, the UE may be monitored by setting an RF at the wireless communication node, where the RF has the same frequency as the base station. When the UE sends the HARQ feedback message to the base station, the wireless communication node monitors that the UE sends the HARQ feedback message and confirms that the UE receives the downlink information.

Fig. 7 is a schematic diagram of a network principle on which the data processing method of the present invention is based. In the network architecture, as shown in fig. 7, SRBs of the UE are connected to the physical layer/medium access control of the base station through the physical layer, DRBs of the UE are connected to the physical layer/medium access control of the wireless communication node through the physical layer, and when there are more idle network resources in the base station, a part of the uplink information transmitted through the DRBs of the UE may also be connected to the base station for processing by the base station. Both the base station and the wireless communication node may communicate uplink information or downlink information with the UE, and as shown in fig. 7, both the base station and the wireless communication node have a function of recognizing a mapping relation of logical channel identifications, when the base station receives a first uplink message or the wireless communication node receives a second uplink message, the base station or the wireless communication node determines the mapping relationship between the logical channel identifier of each piece of uplink information, and specifically, determines that the logical channel identifier of each piece of uplink information has a mapping relationship with the base station or the wireless communication node, for example, when the base station judges that the logical channel identifier of the received first uplink information exists in the mapping relation between the second logical channel identifier and the corresponding wireless communication node, that is, the first uplink information is transmitted through the DRB, the base station forwards the first uplink information to the wireless communication node corresponding to the second logical channel identifier. Similarly, if the wireless communication node determines that the received logical channel identifier of the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, that is, the second uplink information is transmitted through the SRB, the wireless communication node forwards the second uplink information to the base station corresponding to the first logical channel identifier.

Fig. 8 is a signaling flowchart of a further embodiment of the data processing method of the present invention, and based on the results of the UE, the base station, and the wireless communication node shown in fig. 7 and the interaction process, as shown in fig. 8, in this embodiment, a PUCCH that uses the same frequency as the wireless communication node is added to the UE, so that the UE can send an uplink transmission request message and uplink information to the base station or the wireless communication node through the two PUCCHs, respectively, which is taken as an example, and the technical solution of this embodiment is described in detail. The method comprises the following steps:

in step 400, the base station establishes an RRC connection with the UE.

Step 401, the base station establishes a mapping relationship between a first logical channel identifier corresponding to the SRB of the UE and the base station, and a mapping relationship between a second logical channel identifier corresponding to all DRBs of the UE and the wireless communication node.

In this embodiment, it should be further noted that, when there are more idle network resources in the base station, the base station establishes a radio resource control protocol RRC connection with the UE, and establishes a mapping relationship between a third logical channel identifier corresponding to other DRBs except for a part of DRBs of the UE and the base station, so that a part of the first uplink information or the second uplink information transmitted through the DRBs can be processed by the base station.

Step 402, the base station sends an indication message to the wireless communication node, wherein the indication message comprises: the mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relation between the second logical channel identifiers corresponding to all the DRBs of the UE and the wireless communication node.

Specifically, after step 401, since the UE in this embodiment has two PUCCHs capable of sending the uplink transmission request message to the base station or the wireless communication node, in order to accurately transmit each uplink information mapped with the base station or the wireless communication node to the base station or the wireless communication node, at this time, the wireless communication node needs to know the mapping relationship between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relationship between the second logical channel identifiers corresponding to all DRBs of the UE and the wireless communication node, so as to forward the received second uplink information mapped with the base station and transmitted through the SRBs or part of the DRBs to the base station.

In addition, for the case that the base station establishes RRC connection with the user equipment UE and establishes a mapping relationship between the third logical channel identifier corresponding to the DRBs of the UE except for part of the DRBs and the base station, at this time, the indication message sent by the base station to the radio communication node further includes: and mapping relation between the third logical channel identifier corresponding to other DRBs except for part of DRBs of the UE and the base station. Optionally, the wireless communication node may also establish a mapping relationship between the second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or a mapping relationship between the first logical channel identifier corresponding to SRBs of the UE and the base station.

Specifically, when the function of the wireless communication node is strong, the mapping relationship between the second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or the mapping relationship between the first logical channel identifier corresponding to SRBs of the UE and the base station may be established without the base station performing step 402.

Since the UE may randomly send the uplink transmission request message to the base station or the wireless communication node, after the end of step 402, two situations may occur: case one, i.e., the steps contained in block a of fig. 8, and case two, i.e., the steps contained in block B of fig. 8.

The first condition is as follows:

in step 403, the UE sends a first uplink transmission request message to the base station.

Specifically, the first uplink transmission request message is an SR.

In step 404, the base station sends a first uplink transmission grant message to the UE.

Step 405, the UE sends the first uplink information to the base station.

Step 406, the base station determines whether the logical channel identifier included in the first uplink information has a mapping relationship between the second logical channel identifier and the corresponding wireless communication node.

In this embodiment, it should be further noted that there may be three results when the base station identifies the first uplink information, where the result is: if the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, that is, the first uplink information is transmitted through the DRB, it indicates that the wireless communication node needs to perform corresponding processing, and step 407 is executed. And a second result: if the logical channel identifier included in the first uplink information exists in the mapping relationship between the first logical channel identifier corresponding to the SRB and the base station, that is, the first uplink information is transmitted through the SRB, the base station correspondingly processes the first uplink information. And a third result: when the base station has more idle network resources, if the logical channel identifier included in the first uplink information exists in the mapping relationship between the third logical channel identifier and the base station, the base station correspondingly processes the first uplink information.

Step 407, if the base station determines that the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, the base station forwards the first uplink information to the wireless communication node. And (6) ending.

In the case of the first result in step 406, specifically, the base station may generate a first forwarding data packet, where the first forwarding data packet includes the first uplink information, and send the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier. And the wireless communication node correspondingly processes the first uplink information contained in the first forwarding data packet.

Case two:

in step 408, the UE sends a second uplink transmission request message to the wireless communication node.

In step 409, the wireless communication node sends a second uplink transmission grant message to the UE.

In step 410, the UE transmits second uplink information to the wireless communication node.

Step 411, the wireless communication node identifies the second uplink information, and if the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier included in the second uplink information.

Specifically, there may be three possible processing scenarios, processing scenario one: if the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, that is, the second uplink information is transmitted through the SRB, step 412 is executed. The second processing condition is as follows: and if the logical channel identifier contained in the second uplink information exists in the mapping relation between the second logical channel identifier and the wireless communication node, the second uplink information is transmitted through the DRB, and the wireless communication node correspondingly processes the second uplink information. When the base station has more idle network resources, a third processing condition occurs: if the logical channel identifier included in the second uplink information exists in the mapping relationship between the third logical channel identifier and the base station, step 412 is executed.

In step 412, the wireless communication node forwards the second uplink information to the base station.

In the first or third case of step 411, in step 412, specifically, the wireless communication node may generate a second forwarding data packet, where the second forwarding data packet includes second uplink information, and send the second forwarding data packet to the base station, so that the base station performs corresponding processing on the second uplink information included in the second forwarding data packet.

After the wireless communication node sends downlink information to the UE, for the UE having one PUCCH for transmission with the base station, the UE will send HARQ feedback information to the base station through only one PUCCH after receiving the downlink information, but if the downlink information is sent by the wireless communication node, the wireless communication node cannot receive the HARQ feedback information, and thus cannot confirm that the UE successfully receives the downlink information fig. 9 is another schematic diagram of a network principle on which the processing method provided in this embodiment is based. As shown in fig. 9, in order to solve the problem that the wireless communication node cannot receive the HARQ feedback message, a physical layer/medium access control (RF) is added to the wireless communication node, where the RF is the same frequency as the base station, so that when the UE sends the HARQ feedback message to the base station, the wireless communication node listens to the HARQ feedback message through the RF.

However, for a UE that does not have a new PUCCH to communicate with a wireless communication node, the UE can only send an uplink transmission request message, that is, a first uplink transmission request message, to a base station, and when the UE only sends the first uplink transmission request message to the base station and further sends the first uplink information to the base station, in order to avoid the wireless communication node with a monitoring function from monitoring the first uplink transmission request message and the first uplink information, the wireless communication node needs to be set not to respond to the uplink transmission request message of the UE, and on the basis of fig. 8, fig. 10 is a signaling flowchart of a further embodiment of the data processing method according to the present invention. As shown in fig. 10, includes:

step 500, the base station establishes an RRC connection with the UE.

Step 501, the base station establishes a mapping relationship between a first logical channel identifier corresponding to the SRB of the UE and the base station, and a mapping relationship between a second logical channel identifier corresponding to all DRBs of the UE and the wireless communication node.

Step 502, the base station sends an indication message to the wireless communication node, the indication message comprising: the mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relation between the second logical channel identifiers corresponding to all the DRBs of the UE and the wireless communication node.

In step 503, the UE sends a first uplink transmission request message to the base station.

In step 503a, the base station sends an uplink transmission indication message to the wireless communication node.

Specifically, since the radio communication node sets the RF for monitoring the HARQ feedback message, and the RF uses the same frequency as the base station, for the UE without the PUCCH newly added, the base station can only determine that the uplink information is transmitted through the SRB or the DRB, and then the base station processes the uplink information or forwards the uplink information to the radio communication node. In order to prevent the wireless communication node from responding after monitoring the first uplink transmission request message sent by the UE through the RF, the base station sends an uplink transmission indication message to the wireless communication node.

In step 504, the base station sends a first uplink transmission grant message to the UE.

Step 505, the UE sends the first uplink information to the base station.

Step 506, the base station determines whether the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node.

In step 507, if the base station determines that the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node, the base station forwards the first uplink information to the wireless communication node. And (6) ending.

When the wireless communication node transmits downlink information with the UE, the method further comprises the following steps:

step 508, the wireless communication node sends downlink information to the UE.

In step 509, the wireless communication node receives the HARQ feedback message sent by the UE.

On the basis of fig. 9, fig. 11 is a schematic diagram of another network principle of the processing method provided by this embodiment. For a UE having only one PUCCH for transmitting with a base station, when the distance between the UE and a wireless communication node is closer than the distance between the UE and the base station, in order to reduce power consumption of uplink information transmission performed by the UE at this time, after the UE sends a first uplink transmission request message to the base station or the wireless communication node, the base station does not respond to the first uplink transmission request message of the UE, as shown in fig. 11.

For this case, on the basis of fig. 8, fig. 12 is a signaling flow chart of another embodiment of the data processing method of the present invention. As shown in fig. 12, includes:

step 600, the base station establishes an RRC connection with the UE.

Step 601, the base station establishes a mapping relationship between a first logical channel identifier corresponding to the SRB of the UE and the base station and a mapping relationship between a second logical channel identifier corresponding to all DRBs of the UE and the wireless communication node.

Step 602, the base station sends an indication message to the wireless communication node, the indication message includes: the mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station and the mapping relation between the second logical channel identifiers corresponding to all the DRBs of the UE and the wireless communication node.

Since the UE may randomly send the uplink transmission request message to the base station or the wireless communication node, after the end of step 602, two situations may occur: case one, i.e., the steps contained in block a in fig. 12, and case two, i.e., the steps contained in block B in fig. 12.

The first condition is as follows:

step 603, the UE sends a first uplink transmission request message to the base station.

Specifically, the first uplink transmission request message is an SR.

Step 603b, the base station does not respond to the received first uplink transmission request message sent by the UE.

It should be noted that, the second uplink transmission request message in step 608 is not sent by the UE to the wireless communication node actively, but is obtained by the wireless communication node through the additional RF monitoring when the UE sends the first uplink transmission request message to the base station.

Case two:

in step 608, the UE sends a second uplink transmission request message to the wireless communication node.

In step 609, the wireless communication node transmits a second uplink transmission grant message to the UE.

Step 610, the UE sends the second uplink information to the wireless communication node.

Step 611, the wireless communication node identifies the second uplink information, and if the logical channel identifier included in the second uplink information exists in the mapping relationship between the first logical channel identifier and the base station, the wireless communication node forwards the second uplink information to the base station corresponding to the logical channel identifier included in the second uplink information.

Step 612, the wireless communication node forwards the second uplink information to the base station.

Further, similar to fig. 10, in the process of UE downlink transmission by the wireless communication node, as shown in fig. 12, the method includes:

step 613, the wireless communication node sends downlink information to the UE.

In step 614, the wireless communication node receives the HARQ feedback message sent by the UE.

Fig. 13 is a schematic structural diagram of a base station according to an embodiment of the present invention, and as shown in fig. 13, the base station includes: the system comprises a radio resource control protocol RRC connection module 10, a mapping relation establishing module 11, a receiving module, a judging module 13 and a sending module 14.

Specifically, the mapping relationship establishing module 11 establishes a mapping relationship between a first logical channel identifier corresponding to the SRB of the UE and the base station, and/or a mapping relationship between a second logical channel identifier corresponding to all or part of the DRBs of the UE and the wireless communication node, respectively. The embodiment provided with reference to fig. 1 can be divided into three cases, and will not be described herein again.

The receiving module 12 is configured to receive first uplink information sent by the UE. The first uplink information may be transmitted through an SRB or a DRB.

And the judging module 13 is configured to judge whether the logical channel identifier included in the first uplink information exists in a mapping relationship between the second logical channel identifier and the corresponding wireless communication node.

Specifically, the determining module 13 may determine, according to the MAC protocol entity, that the logical channel identifier included in the first uplink information is the first logical channel identifier or the second logical channel identifier, and if the logical channel identifier included in the first uplink information has a mapping relationship between the second logical channel identifier and a corresponding wireless communication node, that is, it indicates that the first uplink information is transmitted through the DRB, the wireless communication node needs to perform corresponding processing on the first uplink information, and the base station forwards the first uplink information to the corresponding wireless communication node. After receiving the first uplink information, the wireless communication node performs corresponding processing on the first uplink information, for example, performs conventional processing such as filtering processing and service access on the first uplink information.

A sending module 14, configured to forward the first uplink information to the wireless communication node corresponding to the logical channel identifier if the determining module 13 determines that the logical channel identifier included in the first uplink information exists in the mapping relationship between the second logical channel identifier and the corresponding wireless communication node.

The base station of this embodiment may execute the technical solution of the method embodiment shown in fig. 1, and the implementation principles thereof are similar, and are not described herein again.

In the base station provided in this embodiment, an RRC connection module establishes an RRC connection with a user equipment UE, a mapping relationship establishing module respectively establishes a mapping relationship between a first logical channel identifier corresponding to an SRB of the UE and the base station and/or a mapping relationship between a second logical channel identifier corresponding to all or part of DRBs of the UE and a wireless communication node, and a receiving module receives first uplink information sent by the UE. And then the judging module judges whether the logical channel identifier contained in the first uplink information exists in the mapping relation between the second logical channel identifier and the corresponding wireless communication node, if so, the sending module forwards the first uplink information to the wireless communication node corresponding to the logical channel identifier. The method and the device realize the function that the first uplink information transmitted by the SRB is processed by the base station, and all or part of the first uplink information transmitted by the DRB is processed by the wireless communication node, so that when the UE moves to other wireless communication nodes, the first uplink information transmitted by the SRB is always processed by the base station, the problem of frequent switching of the SRB and the DRB caused by the fact that the UE moves to other wireless communication nodes is solved, the switching times of the SRB and the DRB are reduced, the mobility performance of the UE is improved, and the utilization rate of idle resources of the base station is effectively improved.

Further, fig. 14 is a schematic structural diagram of a base station according to another embodiment of the present invention, and as shown in fig. 14, on the basis of the embodiment shown in fig. 13, the sending module 14 further includes: packet generation section 141 and transmission section 142.

The data packet generating unit 141 is configured to generate a first forwarding data packet, where the first forwarding data packet includes the first uplink information.

Specifically, referring to the data processing method provided in fig. 1, the base station may send the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier in two ways. And will not be described in detail herein.

A sending unit 142, configured to send the first forwarding data packet to the wireless communication node corresponding to the logical channel identifier.

On the basis of the base station provided in fig. 13, after the RRC connection module 10 establishes the RRC connection with the UE, the sending module 14 is further configured to send an indication message to the wireless communication node.

The indication message contains the mapping relation between the first logical channel identifier corresponding to the SRB of the UE and the base station and/or the mapping relation between the second logical channel identifier corresponding to all or part of the DRBs of the UE and the corresponding wireless communication node.

Specifically, referring to step 103 in the embodiment provided in fig. 2, details are not repeated here.

Preferably, when there are more idle network resources of the base station, the base station may process a part of the first uplink information or the second uplink information transmitted through the DRB, and for this situation, after the RRC connection module 10 establishes the RRC connection with the UE, the mapping relationship establishing module 11 is further configured to establish a mapping relationship between the third logical channel identifier corresponding to another DRB of the UE except for the part of DRBs and the base station.

The indication message sent by the sending module 14 to the wireless communication node further includes: and mapping relation between the third logical channel identifier corresponding to other DRBs except for part of DRBs of the UE and the base station.

Further, the determining module 13 is further configured to determine that, if the logical channel identifier included in the first uplink information exists in the mapping relationship between the first logical channel identifier and the base station or the mapping relationship between the third logical channel identifier and the base station, the base station performs corresponding processing on the first uplink information, where the corresponding processing performed by the base station on the first uplink information is: after receiving the first uplink information, sending a response message to the UE; or, performing conventional processing on the first uplink information, such as filtering processing, service access, and the like.

In this embodiment, after the wireless communication node receives the indication message sent by the sending module 14 of the base station, the wireless communication node may obtain, according to the indication message, the mapping relationship between the SRB and the base station, the DRB and the wireless communication node, or the mapping relationship between the SRB and part of the DRB and the base station, and another part of the DRB and the wireless communication node, so that when the wireless communication node receives the second uplink information sent by the UE or the first uplink information forwarded by the base station, the second uplink information or the forwarded first uplink information is processed by determining whether the second uplink information or the forwarded first uplink information is transmitted through the SRB or the DRB, and according to the logical channel identifier and the mapping relationship of the SRB or the DRB included in the second uplink information or the forwarded first uplink information, or the second uplink information is forwarded to the base station, thereby implementing that the first uplink information transmitted through the SRB or the second uplink information transmitted through the SRB is transmitted through the base station The base station processes the first uplink information transmitted by all or part of the DRBs or the second uplink information transmitted by all or part of the DRBs, and the wireless communication node processes the second uplink information, so that the problem of poor mobility of the UE during roaming caused by processing all the SRBs and the DRBs on the wireless communication node in the prior art is solved, and the utilization rate of idle resources of the base station is effectively improved.

Further, the receiving module 12 is further configured to receive a first uplink transmission request message sent by the UE before receiving the first uplink information sent by the UE. The first uplink transmission request message may be a Scheduling Request (SR).

For a UE that does not have a new PUCCH to transmit with the wireless communication node, however, the UE can only send an uplink transmission request message to the base station, i.e., the first uplink transmission request message, when the UE transmits only the first uplink transmission request message to the base station, further, when transmitting the first uplink information to the base station, in order to avoid the wireless communication node with the monitoring function from monitoring the first uplink transmission request message and the first uplink information, the wireless communication node needs to be configured not to respond to the uplink transmission request message of the UE, therefore, further, the sending module 14 is further configured to, after the receiving module 12 receives the first uplink transmission request message sent by the UE, send an uplink transmission indication message to the wireless communication node, and the wireless communication node does not respond to the received first uplink transmission request message according to the uplink transmission indication message.

Further, the receiving module 12 is further configured to receive a second forwarding data packet sent by the wireless communication node, where the second forwarding data packet is a data packet generated by the wireless communication node according to the received second uplink information sent by the UE.

Further, when the UE detects the base station and the wireless communication node at the same time, it is generally default that the distance between the UE and the wireless communication node is closer, and at this time, in order to reduce power consumption of uplink information transmission performed by the UE, the UE preferentially performs uplink information transmission with the wireless communication node, and the base station needs not to respond to the first uplink transmission request message sent by the UE. At this time, after the receiving module 12 receives the first uplink transmission request message sent by the UE, the sending module 14 does not respond to the received first uplink transmission request message sent by the UE, and the receiving module 12 waits to receive the second forwarding data packet sent by the wireless communication node.

And if the logical channel identifier contained in the second uplink information exists in the mapping relation between the second logical channel identifier and the wireless communication node, namely the second uplink information is transmitted through the DRB, the wireless communication node correspondingly processes the second uplink information. The wireless communication node correspondingly processes the second uplink information as follows: after receiving the second uplink information, sending a response message to the UE; or, performing conventional processing on the second uplink information, such as filtering processing, service access, and the like.

In the wireless communication node provided in this embodiment, the obtaining module obtains a mapping relationship between the second logical channel identifier corresponding to all or part of DRBs of the UE and the wireless communication node and/or a mapping relationship between the first logical channel identifier corresponding to SRBs of the UE and the base station.

Further, when there are more idle network resources in the base station, a part of the wireless communication nodes may be handed over to the base station for processing through the DRB to transmit the second uplink information. Referring to fig. 13, the function of switching the second uplink information, which is transmitted by a part of the wireless communication node through the DRB, to the base station may be implemented in two ways:
