The present disclosure relates to dual connectivity in the communication field, and more particularly, to a data transmission method and apparatus, a storage medium, and a program product.
New Radio-Dual Connectivity (NR-DC) includes a dual-connectivity configuration of low frequency and low frequency in terms of frequency bands. This means that one physical NR station operates as a low frequency cell, and the other physical NR station also operates as a low frequency cell. NR-DC also includes a dual-connectivity configuration of low frequency and high frequency in terms of frequency bands, i.e., one physical NR station operates as a low frequency cell, and the other physical NR station operates as a high frequency cell. Different operators have different deployment modes for low frequency and high frequency under the two NR-DC architectures, requiring equipment manufacturers to adopt various schemes for implementation.
In related technologies, there are mainly three integration methods for the two NR-DC architectures. For example, there are three scenarios for the dual-connectivity configuration of low frequency and high frequency in terms of frequency bands: the NR-DC inter-station non-co-frame scenario, the NR-DC intra-station co-frame co-logical-station scenario, and the NR-DC intra-station co-frame non-co-logical-station scenario. Equipment manufacturers need to recognize the differences among these three deployment scenarios of NR-DC, e.g., differences in control signaling and media data communication. This results in complex hardware deployment, a heavy workload for the development of Operation Process (OP) modules in the three deployment scenarios, high maintenance costs of software versions, unsatisfactory performance, and low efficiency.

The present disclosure provides a data transmission method and apparatus, a storage medium, and a program product. The method may include: determining a deployment mode between a first NR base station and a second NR base station according to second identification information; then generating target identification information according to the deployment mode; generating control signaling according to the target identification information; sending the control signaling carrying the target indication information to the second NR base station, such that a second OP module of the second NR base station creates a second media processing module according to the target identification information in the control signaling; and finally controls a first media processing module to transmit data to the second media processing module according to the deployment mode.

In this way, the data transmission can be realized while ignoring the implementation differences and transmission differences between different deployment scenarios of NR-DC, thereby reducing the complexity of implementation by equipment manufacturers and the complexity of version upgrade by operators.
The embodiments of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.
It should be noted that there is another NR-DC protocol architecture in addition to the NR-DC architecture shown in
It should be noted that one NR station may include one CU and a plurality of DUs, one CU may be divided into a control-plane part (CU-CP) and a user-plane part (CU-UP), and one CU may include one CU-CP and a plurality of CU-UPs. The CU-CP is connected to a DU through an F1-C interface, and the CU-UP is connected to a DU through an F1-U interface.
It should be noted that the F1-C (control plane) interface and the F1-U (user plane) interface are F1 interfaces, the F1 interfaces support signaling exchange and data transmission between the CU and the DU, and the F1 interfaces can separate a radio network layer from a transport network layer, and exchange user terminal-related information or non-user terminal related information, etc.
It should also be noted that a plurality of DUs may be centrally controlled by one CU. In theory, there is no limit to the maximum number of DUs that one CU can be connected to, which is only limited by a specific implementation in practice. Although the 3rd Generation Partnership Project (3GPP) standards stipulate that one DU is connected to only one CU, the possibility of connecting a plurality of CUs to one DU to enhance flexibility in practice is not excluded.
It should be noted that the CU and the DU may be divided according to protocol layers of a wireless network. For example, functions of the Packet Data Convergence Protocol (PDCP) and higher protocol layers (e.g., Radio Resource Control (RRC)) are set in the CU. Functions of protocol layers below the PDCP, such as Radio Link Control (RLC), Media Access Control (MAC), Physical layer (PHY), and the like, are set in the DU.
It should be noted that NR-DC may include a dual-connectivity configuration including a low-frequency NR base station and a low-frequency NR base station in terms of frequency bands, i.e., one NR station is a low-frequency NR base station and the other NR station is also a low-frequency NR base station. Alternatively, NR-DC may include a dual-connectivity configuration including a low-frequency NR base station and a high-frequency NR base station, i.e., one NR station is a low-frequency NR base station and the other NR station is a high-frequency NR base station. There are three main deployment scenarios for the integration of the two NR-DC architectures. A dual-connectivity configuration including a low-frequency NR base station and a high-frequency NR base station is used as an example, as shown in

It should also be noted that the principle of the dual-connectivity configuration including the low-frequency NR base station 500 and the low-frequency NR base station 500 is consistent with the principle of the dual-connectivity configuration including the low-frequency NR base station 500 and the high-frequency NR base station 600.

Those having ordinary skills in the art may know that with the evolution of the NR-DC architecture and the emergence of new application scenarios, the technical schemes provided in the embodiments of the present disclosure are also applicable to similar technical problems.

Based on the above NR-DC architectures, various embodiments of the data transmission method are proposed below.
At S110, the first OP module is controlled to create a first media processing module.
It should be noted that after receiving a measurement report from a UE, the first NR base station controls the first OP module to create the first media processing module, which is not particularly limited in this embodiment.
It should be noted that the first NR base station may be a low-frequency NR base station or a high-frequency NR base station, a frequency range corresponding to the low-frequency NR base station 500 may be 450 MHZ to 6000 MHZ, and a frequency range corresponding to the high-frequency NR base station 600 may be 24250 MHZ to 52600 MHZ, which is not particularly limited herein.
At S120, second identification information of a second NR base station is acquired, and a deployment mode between the first NR base station and the second NR base station is determined according to the second identification information.
In this step, the first NR base station may acquire the second identification information of the second NR base station in various manners. For example, the first NR base station may acquire the second identification information of the second NR base station according to operations, administration and maintenance (OAM) of the first NR base station, and may also acquire the second identification information in other manners, which is not particularly limited herein.
It should be noted that a second OP module is configured in the second NR base station. The second NR base station may be a low-frequency NR base station or a high-frequency NR base station, a frequency range corresponding to the low-frequency NR base station 500 may be 450 MHZ to 6000 MHZ, and a frequency range corresponding to the high-frequency NR base station 600 may be 24250 MHZ to 52600 MHZ, which is not particularly limited herein.
It should also be noted that the second identification information may include a gNBID and a PLMN, which is not particularly limited in this embodiment.
At S130, target identification information is generated according to the deployment mode, control signaling is generated according to the target identification information, and the control signaling is sent to the second NR base station, such that the second OP module creates a second media processing module according to the control signaling.
In this step, because the deployment mode between the first NR base station and the second NR base station is determined in S120, target identification information may be generated according to the deployment mode, then control signaling may be generated according to the target identification information, and the first OP module sends the control signaling to the second OP module of the second NR base station, such that the second OP module of the second NR base station creates a second media processing module according to the control signaling. In this way, in subsequent steps, the first media processing module may be controlled to transmit data to the second media processing module according to the deployment mode.
At S140, the first media processing module is controlled according to the deployment mode to transmit data to the second media processing module.
In this step, because the deployment mode between the first NR base station and the second NR base station is determined in S120 and the second media processing module is created in S130, the first media processing module can be controlled according to the deployment mode to transmit data to the second media processing module.
It should be noted that the data transmission may be data forwarding or other transmission modes, which is not particularly limited herein.
In this embodiment, by the data transmission method including the above steps S110 to S140, the first NR base station controls the first OP module to create a first media processing module, then acquires second identification information of the second NR base station, determines a deployment mode between the first NR base station and the second NR base station according to the second identification information, generates target identification information according to the deployment mode, and then generates control signaling according to the target identification information. Then, the first OP module sends the control signaling to the second OP module of the second NR base station, such that the second OP module of the second NR base station creates a second media processing module according to the control signaling. Finally, the first media processing module may be controlled to transmit data to the second media processing module according to the deployment mode. That is to say, in the schemes of the embodiments of the present disclosure, the first OP module of the first NR base station creates the first media processing module and the second OP module of the second NR base station creates the second media processing module, such that in different deployment modes, the first OP module and the second OP module can interact with each other, and the first media processing module and the second media processing module can also interact with each other. In this way, the data transmission can be realized while ignoring the implementation differences and transmission differences between different deployment scenarios of NR-DC, thereby reducing the complexity of implementation by equipment manufacturers and the complexity of version upgrade by operators.
It should be noted that the first NR base station may be a low-frequency NR base station or a high-frequency NR base station, which is not particularly limited herein. Similarly, the second NR base station may be a low-frequency NR base station or a high-frequency NR base station, which is not particularly limited herein. In addition, a frequency range corresponding to the low-frequency NR base station 500 may be 450 MHZ to 6000 MHZ, and a frequency range corresponding to the high-frequency NR base station 600 may be 24250 MHZ to 52600 MHZ, which is not particularly limited herein.

At S220, when the second identification information exists in the configuration list, first identification information of the first NR base station is acquired, the first identification information is compared with the second identification information, and the deployment mode between the first NR base station and the second NR base station is determined according to a result of the comparison.
Since it is checked in S210 whether the second identification information exists in the configuration list, in this step, if the second identification information exists in the configuration list, first identification information of the first NR base station is acquired, the first identification information is compared with the second identification information, and the deployment mode between the first NR base station and the second NR base station is determined according to a result of the comparison.
It should be noted that the first identification information may include a gNBID and a PLMN of the first NR base station, or may include other information.

When the first identification information is consistent with the second identification information, it is determined that the deployment mode between the first NR base station and the second NR base station is co-frame co-logical-station deployment.
In an embodiment, it is assumed that the first identification information includes a gNBID and a PLMN of the first NR base station, and the second identification information includes a gNBID and a PLMN of the second NR base station. When the gNBID of the first NR base station is consistent with the gNBID of the second NR base station and the PLMN of the first NR base station is consistent with the PLMN of the second NR base station, it indicates that the first identification information is consistent with the second identification information, and it is determined that the deployment mode between the first NR base station and the second NR base station is co-frame co-logical-station deployment; otherwise, it indicates that the first identification information is not consistent with the second identification information, which is not particularly limited in this embodiment.

It should be noted that the embodiment shown in
In an embodiment, it is assumed that the first identification information includes a gNBID and a PLMN of the first NR base station, and the second identification information includes a gNBID and a PLMN of the second NR base station.

For example, a physical address of the second media processing module can be determined from the MAC address of the second media processing module.

An embodiment of the present disclosure includes: controlling a first OP module to create a first media processing module; acquiring second identification information of a second NR base station, and determining a deployment mode between the first NR base station and the second NR base station according to the second identification information, where a second OP module is configured in the second NR base station; generating target identification information according to the deployment mode, generating control signaling according to the target identification information, and sending the control signaling to the second NR base station, such that the second OP module creates a second media processing module according to the control signaling; and controlling, according to the deployment mode, the first media processing module to transmit data to the second media processing module. The schemes of the embodiments of the present disclosure may include: determining a deployment mode between a first NR base station and a second NR base station according to second identification information; then generating target identification information according to the deployment mode; generating control signaling according to the target identification information; sending the control signaling carrying the target indication information to the second NR base station, such that a second OP module of the second NR base station creates a second media processing module according to the target identification information in the control signaling; and finally controls a first media processing module to transmit data to the second media processing module according to the deployment mode. That is to say, in the schemes of the embodiments of the present disclosure, the first OP module of the first NR base station creates the first media processing module and the second OP module of the second NR base station creates the second media processing module, such that in different deployment modes, the first OP module and the second OP module can interact with each other, and the first media processing module and the second media processing module can also interact with each other. In this way, the data transmission can be realized while ignoring the implementation differences and transmission differences between different deployment scenarios of NR-DC, thereby reducing the complexity of implementation by equipment manufacturers and the complexity of version upgrade by operators.
