Description

Processing method under data copying and related equipment

Technical field

The present application relates to the field of communications technologies, and in particular, to a processing method and related device under data replication.

Background technique

In dual connectivity (DC), the replication data transmission mode uses a split bearer protocol architecture. For uplink and downlink, the Packet Data Convergence Protocol (PDCP) layer is located in a certain A cell (Cell Group, CG), such as a Master Cell Group (MCG) or a Secondary Cell Group (SCG), where the CG of the PDCP is an anchor CG. The PDCP layer of the sender device copies the PDCP Protocol Data Unit (PDU) into the same two PDUs, such as one PDCP PDU and one Duplicated PDCP PDU. The two PDCP PDUs pass through the wireless link layer of different CGs. The Radio Link Control (RLC) layer and the Media Access Control (MAC) layer reach the corresponding MAC layer and RLC layer of the receiving end device through the air interface, and finally converge to the PDCP layer of the receiving end device. In the case that the PDCP layer of the receiving end device detects that two PDCP PDUs are the same PDU, the PDCP layer of the receiving end device discards one of the PDUs and delivers another PDU to the upper layer.

In some embodiments, the network device controller may be part of the core network or may be integrated into the network device 101. The network device 101 and the network device 101 can also communicate with each other directly or indirectly via a blackhaul interface 104 (such as an X2 interface).

FIG. 1B shows a schematic diagram of a dual connectivity network architecture. As shown in FIG. 1B, network device 1011 provides a basic network coverage 105. Network device 1012 provides a relatively small network coverage 106. The User Equipment (UE) in the common coverage of the network device 1011 and the network device 1012 will be able to establish a communication connection with the network device 1011 and the network device 1012 at the same time. Here, the case where one user equipment 102 and one network device 1011 and the network device 1012 are simultaneously connected is referred to as a dual connection. As shown in FIG. 1B, under dual connectivity, the network device 1011 is a master node (MN), and the network device 1012 is a slave node (SN).

Figure 1C shows a schematic diagram of an upstream data replication transmission under DC. As shown in FIG. 1C, a User Equipment (UE) includes at least one PDCP entity, two RLC entities, and two MAC entities. Under the data replication, the PDCP entity of the user equipment performs data replication to obtain the PDCP PDU and the duplicate PDCP PDU, and then the PDCP entity PDCP PDU and the duplicate PDCP PDU of the user equipment are respectively delivered to the two RLC entities of the user equipment, and the two user equipments The two RLC entities are respectively delivered to the two MAC entities of the user equipment, and the two MAC entities of the user equipment transmit the two data to the two network devices through the wireless interface, and finally the PDCP entities of one of the network devices perform aggregation.

FIG. 1D shows a schematic diagram of downlink data replication transmission under DC. As shown in FIG. 1D, the network device in cell group (CG1) includes at least one PDCP entity, one RLC entity, and one MAC entity. The network device in CG2 includes at least one RLC entity and one MAC entity. Under data replication, the PDCP entity of the network device at CG1 performs data replication to obtain a PDCP PDU and a duplicate PDCP PDU, and then the PDCP entity of the network device at CG1 delivers the PDCP PDU and the duplicate PDCP PDU to its own RLC entity and The RLC entity of the network device in CG1, the RLC entities of the two network devices respectively deliver the two data to their own MAC entities, and the MAC entities of the two network devices transmit the two data through the wireless interface. The user equipment is finally aggregated in the PDCP entity of the user equipment.

In the existing discussion of NR, for the radio bearer configured with the duplicate data transmission function, the MAC replication control element (Control Element, CE) can be used to dynamically activate or deactivate the data replication transmission function of a certain bearer. . In the DC scenario, the master node (MN) and the slave node (SN) can send MAC CEs to activate or deactivate the replication data function of a split bearer of the user equipment. In this case, The two network nodes are prevented from transmitting the data replication transmission function of the MAC CE to control the user equipment, and coordination between the two network nodes is required to ensure that only one network node performs data replication control on the user equipment.

In this application, first, under the DC, a data replication control rule related to the default path is configured in advance, and the data replication control rule may be a protocol configuration or a network device configuration. If the data replication control rule is configured by the protocol, both network devices and user equipment know; or both network devices know that the user equipment does not know. If the data replication control rule is configured by one of the network devices, the network device of the configuration may send the data replication control rule to another network device and user equipment; or only to another network device.

Then, the second network device first sends a default path configuration information to the first network device and the user equipment. For the second network device, the second network device itself knows whether it wants to control the data replication of the user equipment through the MAC CE. The reason why the second network device sends the default path configuration information to the first network device is to let the first network device know whether the first network device wants to control data replication of the user equipment by using the MAC CE. The reason why the second network device sends the default path configuration information to the user equipment is to let the user equipment know which default path is (so that the subsequent user equipment deactivates the data replication, send data on the default path), and/or let the user equipment Know which network device controls its own data replication transmission function.

It can be seen that in the present application, the second network device sends the default path configuration information to the first network device to ensure that only one network device performs data copy control on the user equipment. In addition, the second network device sends the default path configuration information to the user equipment, so as to achieve the purpose of the subsequent user equipment to explicitly send data on which path in the case of deactivating data replication. In addition, in a case that the user equipment knows the data replication control rule, the second network device sends the default path configuration information to the user equipment to reach the purpose of the user equipment explicitly determining which network device performs data copy control on the user equipment.

On the second network device side, in a case where the first network device controls data replication of the user equipment by using the MAC CE, step c5 is performed; and if the first network device does not control data replication of the user equipment by using the MAC CE, performing steps C6.

Step c3: The first network device sends a first MAC CE to the user equipment, where the first MAC CE is used to activate or deactivate data replication.

Step c4: The first network device sends a fifth MAC CE to the user equipment, where the fifth MAC CE does not include a bit for controlling the target bearer, and the target bearer is a bearer for the second network device to control data replication.

Step c7: The user equipment receives the first MAC CE sent by the first network device, and the user equipment receives the sixth MAC CE sent by the second network device; or the user equipment receives the second MAC CE sent by the first network device, and the user The device receives the fifth MAC CE sent by the second network device. The user equipment activates or deactivates data replication based on the first MAC CE or the third MAC CE.

It should be noted that, in the case that the user equipment knows the above data replication control rule, even if the user equipment receives two MAC CEs, the user equipment knows which network device controls its own data replication, so in this case, the user The device ignores the MAC CE sent by the network device that is not controlling its own data replication.

Step c8: In the case that the user equipment deactivates data replication, the user equipment sends data to the default path.

Step c9: In the case that the user equipment activates data replication, the user equipment sends data to the path where the first network device is located and the path where the second network device is located.

The embodiment shown in Figs. 4A to 4C will be described in detail below.

Wherein, under DC, the first network device is the MN, the second network device is the SN, or the first network device is the SN, and the second network device is the MN.

The path of the primary cell group (MCG) and the path of the secondary cell (SCG) is the path of the primary cell, that is, the path where the MN is located, and the path of the secondary cell is the path where the SN is located.

The default path configuration information is configured by the second network device. When the default path configuration information is related to the MCG path configuration information, it indicates that the default path is the MCG path, and when the default path configuration information is about the SCG path configuration information, it indicates that the default path is the SCG path.

The specific implementation manner of the first network device determining whether to control the data replication of the user equipment by using the MAC CE based on the path configuration information includes: determining, by the first network device, whether the user is controlled by the MAC CE based on the path configuration information and the data replication control rule. Data replication of the device.

Further, the data replication control rule is: when the default path is the path where the first network device is located, the first network device does not control data replication of the user equipment by using the MAC CE; and the default path is the second network device. In the case of the path, the first network device controls data replication of the user equipment through the MAC CE.

Alternatively, the data replication control rule is: when the default path is the path where the first network device is located, the first network device controls data replication of the user equipment by using the MAC CE; where the default path is where the second network device is located. In the case of a path, the first network device does not control data replication of the user equipment through the MAC CE.

It should be noted that the specific implementation manner of the second network device determining whether to control the data replication of the user equipment by using the MAC CE is the same as that of the first network device, and is not described herein.

In the case that the two network devices send the MAC CE to the user equipment, the two devices may be sent to the user equipment at the same time, or may be sent to the user equipment at different times, which is not limited herein.

The user equipment activates or deactivates data replication based on a MAC CE for activation or deactivation. It is easy to understand that, for example, the MAC CE received by the user equipment is Deactivation, then the user equipment deactivates the data, and the user equipment receives the data. The MAC CE to the activation is then the user device activates the data.

In an embodiment of the present application, the specific implementation manner in which the user equipment activates or deactivates data replication according to the first MAC CE or the third MAC CE is:

In the case that the default path is the path where the first network device is located, the user equipment activates or deactivates data replication based on the third MAC CE;

In case the default path is the path in which the second network device is located, the user equipment activates or deactivates the data copy based on the first MAC CE.

Specifically, based on the foregoing data replication control rule, the device that controls data replication of the user equipment is a network device that is not in the default path, and the user equipment also knows the default path configuration information, that is, the user equipment (the user equipment also knows the above data replication). In the case of control rules, it is known that the network device that controls its own data replication is not on the default path. When the two network devices send the MAC CE to the user equipment, if the default path is the path where the first network device is located, and the user equipment knows that the second network device controls its own data replication, the user equipment ignores the first network device. The sent MAC CE controls the data replication based on the MAC CE sent by the second network device only; and the default path is the path where the second network device is located, and the user equipment knows that the first network device controls its own data replication, then The user equipment ignores the MAC CE sent by the second network device, and controls its own data replication based only on the MAC CE sent by the first network device.

In the case that the default path is the path where the first network device is located, the user equipment activates or deactivates data replication based on the first MAC CE;

In case the default path is the path in which the second network device is located, the user equipment activates or deactivates the data copy based on the third MAC CE.

Specifically, based on the foregoing data replication control rule, the device that controls data replication of the user equipment is a network device in a default path, and the user equipment also knows the default path configuration information, that is, the user equipment (the user equipment also knows the above data replication) In the case of control rules, it is known that the network device that controls its own data replication is on the default path. When the two network devices send the MAC CE to the user equipment, if the default path is the path where the first network device is located, and the user equipment knows that the first network device controls its own data replication, the user equipment ignores the second network device. The sent MAC CE controls its own data replication only based on the MAC CE sent by the first network device; and assumes that the default path is the path where the second network device is located, and the user equipment knows that the second network device controls its own data replication, then The user equipment ignores the MAC CE sent by the first network device, and controls its own data replication only based on the MAC CE sent by the second network device.

In an embodiment of the present application, the specific implementation manner in which the user equipment activates or deactivates data replication according to the first MAC CE and the fourth MAC CE includes: deactivating data replication in the first MAC CE, and activating data in the fourth MAC CE. Copy, user device activates data replication.

Or, in an embodiment of the present application, the specific implementation manner of the user equipment for activating or deactivating data replication according to the first MAC CE and the fourth MAC CE is: deactivating data replication in the first MAC CE, the fourth MAC CE Activate data replication and the user device deactivates data replication.

Specifically, in a case where one MAC CE is active data replication and another MAC CE is active data replication, the user equipment side obtains activation data replication based on the two MAC CEs. In the case where one MAC CE is deactivated data replication and the other MAC CE is deactivated data replication, the user equipment side based on the two MAC CEs is definitely deactivated data replication. Since at least one bit in the fourth MAC CE is set to a set value, the set value may be 0 or may be 1. In order to prevent the fourth MAC CE from controlling the data replication of the user equipment, the protocol stipulates that when the two MAC CEs have one MAC CE that is active data replication and the other MAC CE is deactivated, the corresponding one is to activate data replication; or The protocol stipulates that when the two MAC CEs have one MAC CE that activates data replication and the other MAC CE deactivates data replication, the corresponding one is to deactivate data replication.

For example, as shown in FIG. 4D, FIG. 4D is a schematic diagram of a MAC CE provided by an embodiment of the present application. Shown in Figure 4D, C _1- C ₇ represents the bit corresponding to the radio bearer, R represents a reserved bit, when a radio bearer corresponding to the bit is 0, the deactivation, when a radio bearer corresponding to When the bit is 1, it indicates activation. Assume that the user carries the wireless device _{_{_{C 7, C 6, C 5}}} . Because the first network device knows that it wants to control the data replication transmission of the user equipment, the first MAC CE sent by the first network device is determined by the first network device according to its actual situation. Assuming that the first MAC CE is 10100000, corresponding to the visible C ₇ bits are 1, C ₆ corresponding to bits 0, C ₅ visible bit corresponding to 1. Since the second network device does not know his own user to control the transmission of data replication device, the third network device transmits a second MAC CE in C _7, C _6, C ₅ corresponding to bits are set to a fixed value, it is assumed that The fixed value is 1, then the second MAC CE is 11100000. On the user equipment side, the user equipment does not know which MAC CE contains the value of the bit. Therefore, the user equipment performs the operation and the two MAC CEs to obtain the values corresponding to C ₇ , C ₆ , and C ₅ . 1, 0, 1 (the same value as C ₇ , C ₆ , C ₅ in the first MAC CE), it can be seen that in this case, the first network device also functions to control the data replication transmission function of the user equipment.

Also assume that the fixed value is 0, then the second MAC CE is 00000000. On the user equipment side, the user equipment does not know which MAC CE contains the value of the bit. Therefore, the user equipment performs or operates the two MAC CEs to obtain the values corresponding to C ₇ , C ₆ , and C ₅ . 1, 0, 1 (the same value as C ₇ , C ₆ , C ₅ in the first MAC CE), it can be seen that in this case, the first network device also functions to control the data replication transmission function of the user equipment.

It should be noted that, according to the specific implementation principle that the user equipment activates or deactivates data replication according to the second MAC CE and the third MAC CE, and the user equipment is activated or deactivated according to the first MAC CE and the fourth MAC CE, It is not described here.

In an embodiment of the present application, the specific implementation manner in which the user equipment activates or deactivates data replication according to the first MAC CE and the sixth MAC CE includes: deactivating data replication in the first MAC CE, and activating data in the fourth MAC CE. Copy, user device activates data replication.

In an embodiment of the present application, the specific implementation manner of the second network device sending the default path configuration information to the first network device and the user equipment is: when the data replication bearer is established, the second network device is configured to the first network. The device and user equipment send default path configuration information.

Specifically, in the case that a data replication bearer is first established, on the first network device side, the first network device does not know whether it wants to control the data replication transmission function of the bearer. On the user equipment side, the user equipment does not know the default. Which path is, and/or does not know which network device is to control its own data replication transmission function, so in this case, the second network device needs to send default path configuration information to the first network device and user equipment, and notify the time The specific conditions of the bearer of the first network device and the user equipment, thereby achieving the purpose of timely controlling data replication.

In an embodiment of the present application, the specific implementation manner of the second network device sending the default path configuration information to the first network device and the user equipment is: if the default path of an established data replication bearer needs to be modified, The second network device sends default path configuration information to the first network device and the user equipment.

Specifically, in the case of modifying a default path of an already established data replication bearer, on the first network device side, the first network device is not aware of whether it wants to control the data replication transmission function of the established bearer, in the user equipment. On the side, the user equipment does not know which default path of the established bearer is, and/or does not know which network device is to control its own data copy transmission function, so in this case, the second network device needs to go to the first network. The device and the user equipment send the default path configuration information, and notify the first network device and the user equipment of the established bearer in time to achieve the purpose of timely controlling data replication.

In an embodiment of the present application, the user equipment sends data to the default path, where the user equipment sends data to the default path if the data to be sent by the user equipment is less than or equal to the threshold. .

Further, the method further includes:

The user equipment sends data in a path where the first network device is located and a path where the second network device is located, where the data to be sent by the user equipment is greater than the threshold value; The data sent by the path where the first network device is located is different from the data sent by the path where the second network device is located.

Specifically, in the case that the data replication is deactivated and the data to be sent by the user equipment is less than or equal to a threshold, at this time, since the user equipment needs to send less data, the data can be sent only on one path. In the case that the data replication is deactivated and the data to be sent by the user equipment is greater than the threshold, at this time, since the user equipment needs to send more data, if the user equipment uses only one path to send data, the data transmission efficiency may be low. In this case, in order to improve data transmission efficiency, the user equipment sends data by using two paths. For example, the data to be sent by the user equipment includes data 1, data 2, data 3, data 4, data 5, and data 6, and the user equipment Data 1, data 2, and data 3 are transmitted on the path where the first network device is located, and data 4, data 5, and data 6 are transmitted on the path where the second network device is located.

The above method is exemplified based on the above explanation.

First example: Assume that under DC, the second network device is the MN and the first network device is the SN. First, the MN sends the default path configuration information to the SN and the user equipment. It is assumed that the default path configuration information is the configuration information of the MCG, and the default path is the path where the second network device is located. The second network device knows that the first network device controls data replication of the user equipment by using the MAC CE, and therefore the second network device does not send the MAC CE. After the first network device receives the default path configuration information, the first network device knows that it controls the data copy of the user equipment by using the MAC CE based on the default path configuration information, so the first network device sends one for the user equipment to activate or go. Activate the MAC CE for data replication. Assuming that the MAC CE is Deactivation, the user equipment deactivates data replication after receiving the MAC CE. After the user equipment deactivates the data replication, the user equipment sends data to the MCG path. It is also assumed that the MAC CE is activation, and the user equipment activates data replication after receiving the MAC CE. After the user equipment activates data replication, the user equipment sends data to the MCG and SCG paths.

Second example: Assume that under DC, the second network device is the MN and the first network device is the SN. First, the MN sends the default path configuration information to the SN and the user equipment. It is assumed that the default path configuration information is the configuration information of the MCG, and the default path is the path where the second network device is located. The second network device knows that the first network device controls the data replication of the user equipment through the MAC CE, so the second network device sends a MAC CE (if MAC CE-1) that is not used to activate or deactivate the data replication. After the first network device receives the default path configuration information, the first network device knows that it controls the data copy of the user equipment by using the MAC CE based on the default path configuration information, so the first network device sends one for the user equipment to activate or go. Activate the MAC CE for data replication (if MAC CE-2). Since the user equipment receives the MAC CE-1 and the MAC CE-2, because the user equipment controls the data replication of the first network device based on the default path configuration information, the user equipment ignores the MAC CE-1 and performs only based on the MAC CE-2. Activate or deactivate. Assuming that the MAC CE-2 is Deactivation, the user equipment deactivates data replication after receiving the MAC CE. After the user equipment deactivates the data replication, the user equipment sends data to the MCG path. Also assume that the MAC CE-2 is activation. After receiving the MAC CE, the user equipment activates data replication. After the user equipment activates data replication, the user equipment sends data to the MCG and SCG paths.

It should be noted that the above examples are for explanation only and should not be construed as limiting.
