Abstract
Description
[Technical Field]
[0001] This application is filed based on a Chinese patent application bearing application number 202111498509.X and filed on December 9, 2021, and claims priority to that Chinese patent application, the entire contents of which are incorporated herein by reference.
[0002] The present application relates to dual connections in the field of communications, and in particular to a data transmission method and device, storage medium, and program product therefor. [Background technology]
[0003] New Radio-Dual Connectivity (NR-DC) is a dual connectivity that includes low-frequency and low-frequency bands, i.e., one physical NR station is a low-frequency cell and the other physical NR station is also a low-frequency cell. NR-DC also includes low-frequency and high-frequency dual connectivity, i.e., one physical NR station is a low-frequency cell and the other physical NR station is also a high-frequency cell. Different manufacturers have different deployment forms for low-frequency and high-frequency bands under the two NR-DC architectures, which means that equipment manufacturers will need multiple solutions for implementation.
[0004] Related technologies offer three main approaches to integrating the two NR-DC architectures. For example, dual connectivity, including both low- and high-frequency bands, can be achieved through three scenarios: non-common frames between NR-DC stations, common frames and common logic stations within NR-DC stations, and common frames and non-common logic stations within NR-DC stations. To achieve implementation, equipment manufacturers must be aware of the differences between NR-DC in the three deployment scenarios. For example, differences in control signaling and media data communication complicate hardware deployment. The operation process (OP) module requires high development workloads, high software version maintenance costs, poor performance, and low efficiency in the three deployment scenarios.

[0014] In order to clarify the purpose, technical solution and advantages of the present application, the present application will be described in more detail below with reference to the drawings and examples. The specific examples described in this specification are only used to interpret the present application and are not used to limit the present application.
[0015] It should be noted that, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown in the flowchart. In the description of the specification and claims and the accompanying drawings mentioned above, plural (or plural) means two or more, and terms such as "greater than," "less than," and "exceed" are understood to be exclusive of the number, and terms such as "greater than," "less than," and "within" are understood to be inclusive of the number.

[0016] The present application provides a data transmission method, an apparatus therefor, a storage medium, and a program product therefor. The data transmission method includes determining a deployment configuration between a first new radio base station and a second new radio base station based on second identification information, generating target identification information according to the deployment configuration, generating control signaling based on the target identification information, transmitting the control signaling including the target identification information to the second new radio base station so that a second operation processing module of the second new radio base station creates a second media processing module based on the target identification information in the control signaling, and finally controlling the first media processing module to transmit data to the second media processing module according to the deployment configuration. That is, in an embodiment of the present application, by creating the first media processing module using the first operation processing module of the first new radio base station and creating the second media processing module using the second operation processing module of the second new radio base station, the first operation processing module and the second operation processing module can interact with each other in any deployment configuration. Therefore, data transmission can be achieved without regard to differences in implementation and transmission between different deployment scenarios NR-DC, reducing the complexity of implementation for device manufacturers and the complexity of carrier version upgrades.
[0017] Hereinafter, the embodiments of the present invention will be further described with reference to the drawings.
[0018] As shown in Figure 1, Figure 1 is a schematic diagram of an NR-DC architecture configured to perform a data transmission method according to one embodiment of the present application. In the example of Figure 1, user equipment (UE) (not shown) is connected to two NRs, one of which functions as a first New Radio Base Station 200 and the other NR functions as a second New Radio Base Station 300. The first New Radio Base Station 200 is connected to a 5th Generation Core Network (5G Core Network) 100 via an NG-C interface (a user plane interface between a Next Generation Radio Access Network (NG-RAN) and the 5GC 100) and an NG-U interface (a control plane interface between the NG-RAN and the 5GC 100), and the SN is connected to the 5GC 100 via the NG-U interface.
[0019] In addition to the NR-DC architecture shown in Figure 1, the NR-DC also has another protocol architecture. As shown in Figure 2, in the example of Figure 2, a UE (not shown) is connected to only one NR, and this NR functions as a third New Radio Base Station 400 including two distributed units (DUs), one DU functions as an MCG 420 (Master Cell Group) and the other DU functions as an SCG 430 (Secondary Cell Group). This SCG 430 is connected to a CU 410 (Centralized Unit) via an F1-C (Control Plane) interface and an F1-U (User Plane) interface. This SCG 430 is connected to the CU 410 via an F1-C interface and an F1-U interface. The CU 410 is connected to the 5GC 100 via an NG-C interface and an NG-U interface.
[0020] One NR may include one CU and multiple DUs, and one CU may be divided into a control plane unit (CU-CP) and a user plane unit (CU-UP), and one CU may include one CU-CP and multiple CU-UPs. Here, the CU-CP is connected to the DU via an F1-C interface, and the CU-UP is connected to the DU via an F1-U interface.
[0021] In addition, the F1-C (control plane) interface and the F1-U (user plane) interface belong to the F1 interface, which supports signaling exchange and data transmission between the CU and the DU. The F1 interface separates the radio network layer and the transport network layer and can exchange user terminal-related information and non-user terminal-related information.
[0022] Note that multiple DUs can be centrally controlled by one CU, and theoretically, there is no limit to the maximum number of DUs that can be connected to one CU, with the number being subject to practical limitations in specific implementations. The 3GPP (registered trademark) standard specifies that one DU can be connected to only one CU, but this does not preclude connecting multiple CUs to the same DU to improve fault tolerance in actual operation.
[0023] The CU and DU may be divided according to the protocol layer of the wireless network. For example, the functions of the packet data convergence protocol (PDCP) layer and higher protocol layers (e.g., radio resource control (RRC)) may be configured in the CU. The functions of protocol layers below PDCP, such as radio link control (RLC), medium access control (MAC), and physical layer (PHY), are configured in the DU.
[0024] NR-DC may also include dual connections between low-frequency new radio base stations and low-frequency new radio base stations in a frequency band, i.e., one NR is a low-frequency new radio base station and another NR is also a low-frequency new radio base station. Alternatively, NR-DC may include dual connections between low-frequency new radio base stations and high-frequency new radio base stations, i.e., one NR is a low-frequency new radio base station and another NR is a high-frequency new radio base station. There are three main deployment scenarios for integrating the two types of NR-DC architectures, as shown in Figures 3 to 5, using dual connections between low-frequency new radio base stations and high-frequency new radio base stations as examples.
[0025] In the example of Figure 3, the deployment form of the low frequency new radio base station 500 and the high frequency new radio base station 600 is inter-station non-common frame deployment, that is, the low frequency new radio base station 500 and the high frequency new radio base station 600 become two stations in terms of hardware and two stations in terms of logic. The first centralized unit 520 of the low-frequency new radio base station 500 and the second centralized unit 620 of the high-frequency new radio base station 600 are independent of each other, the first distributed unit 510 of the low-frequency new radio base station 500 and the second distributed unit 610 of the high-frequency new radio base station 600 are independent of each other, the Public Land Mobile Network (PLMN) and Generation Node Base Identity document (gNBID) of the low-frequency new radio base station 500 are independent of the PLMN and gNBID of the high-frequency new radio base station 600, and the Internet Protocol (IP) addresses, NG interfaces, and XN interfaces of the low-frequency new radio base station 500 and the high-frequency new radio base station 600 are also independent of each other. Here, the NG interface includes an NG-C interface and an NG-U interface, and the XN interface is a network interface between NG-RAN nodes. The low frequency new radio base station 500 is connected to the 5GC 100 via the NG-C interface and the NG-U interface, and the high frequency new radio base station 600 is connected to the 5GC 100 via the NG-U interface. Note that in an NR-DC scenario, the low frequency new radio base station 500 and the high frequency new radio base station 600 need to transmit control signaling via the XN interface to perform media data communication.
[0026] In the example of FIG. 4 , the deployment mode of the low-frequency new radio base station 500 and the high-frequency new radio base station 600 is a common frame / common logic station deployment. That is, the low-frequency new radio base station 500 and the high-frequency new radio base station 600 are one station in terms of hardware and one station in terms of logic. The low-frequency new radio base station 500 and the high-frequency new radio base station 600 share the first centralized unit 520. The first distributed unit 510 of the low-frequency new radio base station 500 and the second distributed unit 610 of the high-frequency new radio base station 600 are independent of each other. The low-frequency new radio base station 500 and the high-frequency new radio base station 600 share the PLMN, gNBID, IP address, and NG interface. Here, the NG interface includes an NG-C interface and an NG-U interface. Both the low-frequency new radio base station 500 and the high-frequency new radio base station 600 are connected to the 5GC 100 via the NG-C interface and the NG-U interface. In addition, the first centralized unit 520 has a common protocol layer RRC (Radio Resource Control), a General Packet Radio Service Tunneling Protocol user plane (GTPU), and a Service Data Adaptation Protocol (SDAP), and the low-frequency new radio base station 500 and the high-frequency new radio base station 600 transmit control signaling through a custom logical interface in a frame to perform media data communication in an NR-DC scenario.
[0027] In the example of Figure 5, the deployment mode of the low-frequency new radio base station 500 and the high-frequency new radio base station 600 is common frame / uncommon logical station deployment. That is, the low-frequency new radio base station 500 and the high-frequency new radio base station 600 are one station in terms of hardware but two stations in terms of logic. The first centralized unit 520 of the low-frequency new radio base station 500 and the second centralized unit 620 of the high-frequency new radio base station 600 are independent of each other. The first distributed unit 510 of the low-frequency new radio base station 500 and the second distributed unit 610 of the high-frequency new radio base station 600 are independent of each other. The PLMN and gNBID of the low-frequency new radio base station 500 and the PLMN, gNBID, IP address, and NG interface of the high-frequency new radio base station 600 are also independent of each other. Here, the NG interface includes an NG-C interface and an NG-U interface. The low frequency new radio base station 500 and the high frequency new radio base station 600 are both connected to the 5GC 100 via an NG-C interface and an NG-U interface. In an NR-DC scenario, the low frequency new radio base station 500 and the high frequency new radio base station 600 transmit control signaling via a logical XN interface to perform media data communication.
[0028] In addition, the frequency range corresponding to the low-frequency new radio base station 500 may be 450 MHZ to 6000 MHZ, and the frequency range corresponding to the high-frequency new radio base station 600 may be 24250 MHZ to 52600 MHZ, and there are no particular limitations here.
[0029] In addition, the principle of dual connection of the low frequency new radio base station 500 and the low frequency new radio base station 500 is consistent with the principle of dual connection of the low frequency new radio base station 500 and the high frequency new radio base station 600.
[0030] The NR-DC architecture and application scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions of the embodiments of the present application, and are not intended to limit the technical solutions of the embodiments of the present application. As the NR-DC architecture evolves and new application scenarios emerge, the technical solutions of the embodiments of the present application will be equally applicable to similar technical problems.
[0031] The NR-DC architectures shown in Figures 1 and 2 and the NR-DC deployment scenarios shown in Figures 3 to 5 are not intended to limit the scope of the present application, which may include more or fewer components than those shown, may combine some components, or may have different deployments of components.
[0032] Based on the above NR-DC architecture, various embodiments of data transmission methods are proposed below.
[0033] As shown in Figure 6, Figure 6 is a flowchart of a data transmission method according to an embodiment of the present application, which can be applied to a first new radio base station, such as the first new radio base station in the NR-DC architecture shown in Figure 1. A first operation processing module is disposed in the first new radio base station, and the data transmission method may include, but is not limited to, steps S110, S120, S130, and S140.
[0034] Step S110: The first operation processing module is controlled so that the first operation processing module creates a first media processing module.
[0035] In addition, when the first new radio base station receives a detection report from a UE, the first operation processing module controls the first operation processing module to create a first media processing module, but this embodiment is not particularly limited to this.
[0036] In addition, the first new radio base station may be a low-frequency new radio base station or a high-frequency new radio base station, and the frequency range corresponding to the low-frequency new radio base station 500 may be 450 MHZ to 6000 MHZ, and the frequency range corresponding to the high-frequency new radio base station 600 may be 24250 MHZ to 52600 MHZ, and there are no particular limitations here.
[0037] Step S120: Obtain second identification information of the second new radio base station, and determine a deployment mode between the first new radio base station and the second new radio base station according to the second identification information.
[0038] In this step, there are many ways for the first new radio base station to obtain the second identification information of the second new radio base station, for example, the first new radio base station may obtain the second identification information of the second new radio base station based on the operations, administration and maintenance (OAM) of the first new radio base station, or may obtain it in other ways, but this is not particularly limited here.
[0039] In addition, the second new radio base station is provided with a second operation processing module. The second new radio base station may be a low frequency new radio base station or a high frequency new radio base station, and the frequency range corresponding to the low frequency new radio base station 500 may be 450 MHZ to 6000 MHZ, and the frequency range corresponding to the high frequency new radio base station 600 may be 24250 MHZ to 52600 MHZ, and there is no particular limitation here.
[0040] The second identification information may include a gNBID and a PLMN, but this embodiment does not particularly limit this.
[0041] Step S130: Generate target identification information according to the deployment form, generate control signaling based on the target identification information, and send the control signaling to the second new radio base station so that the second operation processing module generates the second media processing module according to the control signaling.
[0042] In this step, since the deployment configurations of the first new radio base station and the second new radio base station are determined in step S120, target identification information is generated according to the deployment configuration, and then control signaling is generated based on the target identification information, and then the first operation processing module sends the control signaling to the second operation processing module of the second new radio base station, so that the second operation processing module of the second new radio base station creates the second media processing module according to the control signaling, thereby facilitating the next step of controlling the first media processing module to transmit data to the second media processing module according to the deployment configuration.
[0043] Step S140: According to the deployment mode, the first media processing module is controlled so that the first media processing module transmits data to the second media processing module.
[0044] In this step, since the deployment configuration of the first new radio base station and the second new radio base station is determined in step S120 and the second media processing module is created in step S130, the first media processing module can be controlled to transmit data to the second media processing module according to the deployment configuration.
[0045] This data transmission may be reverse data transmission or may be another transmission method, but is not particularly limited here.
[0046] In this embodiment, by adopting the data transmission method including the above steps S110 to S140, the first new radio base station controls the first operation processing module to create a first media processing module, then obtains the second identification information of the second new radio base station, determines a deployment mode between the first new radio base station and the second new radio base station based on the second identification information, generates target identification information according to the deployment mode, then generates control signaling based on the target identification information, and then sends the control signaling by the first operation processing module to the second operation processing module of the second new radio base station, so that the second operation processing module of the second new radio base station creates the second media processing module according to the control signaling, and finally controls the first media processing module to transmit data to the second media processing module according to the deployment mode. In other words, in this embodiment, the first media processing module is created by the first operation processing module of the first new radio base station, and the second media processing module is created by the second operation processing module of the second new radio base station. This allows the first operation processing module and the second operation processing module to interact with each other in either deployment mode, and also allows the first media processing module and the second media processing module to interact with each other. This allows data transmission to be achieved regardless of differences in implementation and transmission of NR-DC in different deployment scenarios, reducing the implementation complexity for device manufacturers and the complexity of carrier upgrades.
[0047] The first new radio base station may be a low-frequency new radio base station or a high-frequency new radio base station, but this is not particularly limited. Similarly, the second new radio base station may be a low-frequency new radio base station or a high-frequency new radio base station, but this is not particularly limited. In addition, the frequency range corresponding to the low-frequency new radio base station 500 may be 450 MHz to 6000 MHz, and the frequency range corresponding to the high-frequency new radio base station 600 may be 24250 MHz to 52600 MHz, but this is not particularly limited.
[0048] In one embodiment, as shown in FIG. 7, step S120 will be described, and step S120 may include, but is not limited to, step S210 and step S220.
[0049] Step S210: Obtain the configuration list, and determine whether the second identification information exists in the configuration list.
[0050] In this step, the first new radio base station obtains its own configuration list and checks whether the second identification information exists in the configuration list.
[0051] Step S220: If the second identification information exists in the configuration list, obtain the first identification information of the first new radio base station, compare the first identification information with the second identification information, and determine the deployment mode between the first new radio base station and the second new radio base station according to the comparison result.
[0052] In this step, step S210 checks whether the second identification information exists in the configuration list. If the second identification information exists in the configuration list, the first identification information of the first new radio base station is obtained, and the first identification information and the second identification information are compared. According to the result of the comparison, the deployment mode between the first new radio base station and the second new radio base station is determined.
[0053] The first identification information may include the gNBID and PLMN of the first new radio base station, or other information. Similarly, the second identification information may include the gNBID and PLMN of the second new radio base station, or other information, and is not particularly limited here.
[0054] In this embodiment, by adopting the data transmission method of the above steps S210 and S220, the first new radio base station obtains its own configuration list, determines whether the second identification information exists in the configuration list, and if the second identification information exists in the configuration list, obtains the first identification information of the first new radio base station, compares the first identification information with the second identification information, and determines the deployment mode between the first new radio base station and the second new radio base station according to the comparison result.
[0055] In one embodiment, the first new radio base station obtains its own configuration list, and if the gNBID and PLMN of the second new radio base station are present in the configuration list, it indicates that the first new radio base station and the second new radio base station are in a common frame; otherwise, it indicates that the first new radio base station and the second new radio base station are in separate frames, but this embodiment is not particularly limited to this.
[0056] In one embodiment, as shown in FIG. 8, step S220 will be described, and step S220 may include step S310, but is not limited thereto.
[0057] Step S310: If the first identification information and the second identification information are consistent, the deployment mode between the first new radio base station and the second new radio base station is determined as common frame-common logical station deployment.
[0058] In this embodiment, in step S220, it is determined that the second identification information exists in the configuration list of the first new radio base station, so the first new radio base station obtains its own first identification information, compares the first identification information with the second identification information, and if the first identification information and the second identification information match, determines the deployment mode between the first new radio base station and the second new radio base station as common frame-common logic station deployment.
[0059] In one embodiment, it is assumed that the first identification information includes the gNBID and PLMN of the first new radio base station, and the second identification information includes the gNBID and PLMN of the second new radio base station. If the gNBID of the first new radio base station matches the gNBID of the second new radio base station, and the PLMN of the first new radio base station matches the PLMN of the second new radio base station, the first identification information and the second identification information match, and the deployment mode between the first new radio base station and the second new radio base station is determined to be common frame-common logical station deployment; otherwise, it is determined that the first identification information and the second identification information do not match, but this embodiment is not particularly limited to this.
[0060] In another embodiment, as shown in FIG. 9, step S220 is described, which may include, but is not limited to, step S410.
[0061] Step S410: If the first identification information and the second identification information do not match, determine the deployment mode between the first new radio base station and the second new radio base station as common frame / non-common logical station deployment.
[0062] In this embodiment, in step S220, it is determined that the second identification information exists in the configuration list of the first new radio base station. Therefore, the first new radio base station acquires its own first identification information, compares the first identification information with the second identification information, and if the first identification information and the second identification information do not match, determines the deployment mode between the first new radio base station and the second new radio base station as common frame / non-common logical station deployment.
[0063] The embodiment shown in FIG. 9 is an embodiment parallel to the embodiment shown in FIG. 8, and corresponds to different deployment forms.
[0064] In one embodiment, assuming that the first identification information includes the gNBID and PLMN of the first new radio base station and the second identification information includes the gNBID and PLMN of the second new radio base station, if the gNBID of the first new radio base station matches the gNBID of the second new radio base station but the PLMN of the first new radio base station does not match the PLMN of the second new radio base station, it indicates that the first identification information and the second identification information do not match, and the deployment mode between the first new radio base station and the second new radio base station is determined as common frame / unshared logical station deployment. Alternatively, if the gNBID of the first new radio base station and the gNBID of the second new radio base station do not match but the PLMN of the first new radio base station and the PLMN of the second new radio base station match, it indicates that the first identification information and the second identification information do not match, and the deployment mode between the first new radio base station and the second new radio base station is determined as common frame / unshared logical station deployment. Alternatively, if the gNBID of the first new radio base station does not match the gNBID of the second new radio base station, and the PLMN of the first new radio base station does not match the PLMN of the second new radio base station, this indicates that the first identification information and the second identification information do not match, and the deployment mode between the first new radio base station and the second new radio base station is determined to be common frame / non-common logical station deployment, but this embodiment does not particularly limit this.
[0065] In one embodiment, step S140 will be described as shown in FIG. 10. Step S140 may include, but is not limited to, steps S510 and S520 when the deployment type between the first new radio base station and the second new radio base station is determined as a common frame / common logical station deployment.
[0066] Step S510: The IP address and MAC address of the second media processing module are set in the first media processing module.
[0067] In this step, if the deployment mode between the first new radio base station and the second new radio base station is determined to be common frame-common logical station deployment, the first operation processing module sets the IP address and MAC address of the second media processing module and sends the IP address and MAC address of the second media processing module to the first media processing module so as to control the first media processing module to transmit data to the second media processing module according to the IP address and MAC address of the second media processing module in the next step.
[0068] Step S520: Control the first media processing module so that the first media processing module transmits data to the second media processing module according to the IP address and MAC address of the second media processing module.
[0069] This data transmission may be reverse data transmission or may be another transmission method, but is not particularly limited here.
[0070] In this step, since the IP address and MAC address of the second media processing module are obtained in step S510, the first new radio base station can control the first media processing module so that the first media processing module transmits data to the second media processing module according to the IP address and MAC address of the second media processing module.
[0071] In this embodiment, by adopting the data transmission method including the above steps S510 to S520, when the deployment mode between the first new radio base station and the second new radio base station is determined as common frame-common logical station deployment, the first operation processing module sets the IP address and MAC address of the second media processing module, sends the IP address and MAC address of the second media processing module to the first media processing module, and controls the first media processing module to transmit data to the second media processing module according to the IP address and MAC address of the second media processing module.
[0072] The media access control address (MAC address), also known as the LAN address, Ethernet (registered trademark) address, or physical address, is an address that can be used to identify the location of a device on a network; for example, the MAC address of a second media processing module can determine the physical address of the second media processing module.
[0073] In one embodiment, step S140 will be described as shown in FIG. 11. Step S140 may include, but is not limited to, steps S610 and S620 when the deployment type between the first new radio base station and the second new radio base station is determined as common frame / non-common logical station deployment.
[0074] Step S610: Control the first operation processing module so that the first operation processing module creates a first transmission platform.
[0075] In this step, if the deployment mode between the first new radio base station and the second new radio base station is determined as common frame / non-common logical station deployment, the first new radio base station can control the first operation processing module to create a first transmission platform so that in the next step, the first media processing module transmits data to the second media processing module via the intranet port of the first transmission platform.
[0076] Step S620: Control the first media processing module to transmit data to the second media processing module via an intranet port of the first transmission platform.
[0077] In this step, since the first transmission platform is created in step S610, the first media processing module is controlled so that the first media processing module transmits data to the second media processing module via the intranet port of the first transmission platform.
[0078] This data transmission may be reverse data transmission or may be another transmission method, but is not particularly limited here.
[0079] In this embodiment, by adopting the data transmission method including the above steps S610 to S620, when the deployment mode between the first new radio base station and the second new radio base station is determined as common frame / non-common logical station deployment, the first new radio base station controls the first operation processing module so that the first operation processing module creates a first transmission platform, and then the first media processing module can transmit data to the second media processing module through the intranet port of the first transmission platform.
[0080] In one embodiment, as shown in FIG. 12, step S120 will be described, and step S120 may include, but is not limited to, step S710.
[0081] Step S710: If the second identification information does not exist in the configuration list, determine the deployment mode between the first new radio base station and the second new radio base station as inter-station non-common frame deployment.
[0082] In this embodiment, the first new radio base station obtains its own configuration list and checks whether the configuration list includes the second identification information. If the second identification information does not exist in the configuration list, the deployment mode between the first new radio base station and the second new radio base station is determined to be inter-station non-common frame deployment, but this embodiment is not particularly limited thereto.
[0083] The second identification information may include the gNBID and PLMN of the second new radio base station, or may include other information, but is not particularly limited here.
[0084] The embodiment shown in FIG. 12 belongs to a group of embodiments parallel to the embodiment shown in FIG. 9 and the embodiment shown in FIG. 8, and corresponds to different deployment forms.
[0085] In one embodiment, as shown in FIG. 13, step S140 will be described. When the deployment mode between the first new radio base station and the second new radio base station is determined as inter-station non-common frame deployment, step S140 may include, but is not limited to, steps S810 and S820.
[0086] Step S810: Control the first operation processing module so that the first operation processing module creates a first transmission platform.
[0087] In this step, if the deployment mode between the first new radio base station and the second new radio base station is determined as inter-station non-common frame deployment, the first new radio base station can control the first operation processing module so that in the next step, the first media processing module transmits data to the second transmission platform of the second new radio base station through the external network port of the first transmission platform, and the first operation processing module creates the first transmission platform to transmit data to the second media processing module through the second transmission platform.
[0088] Step S820: Control the first media processing module so that the first media processing module transmits data to the second transmission platform of the second new radio base station through the external network port of the first transmission platform, so that the first media processing module transmits data to the second media processing module through the second transmission platform.
[0089] In this step, since the first transmission platform is created in step S810, the first media processing module controls the first media processing module to transmit data to the second transmission platform of the second new radio base station through the external network port of the first transmission platform, so that the first media processing module transmits data to the second media processing module through the second transmission platform.
[0090] This data transmission may be reverse data transmission or may be another transmission method, but is not particularly limited here.
[0091] In this embodiment, by adopting the data transmission method including the above steps S810 to S820, when the deployment mode between the first new radio base station and the second new radio base station is determined as inter-station non-common frame deployment, the first new radio base station controls the first operation processing module so that the first operation processing module creates a first transmission platform, and then the first media processing module can transmit data to the second transmission platform of the second new radio base station through the external network port of the first transmission platform, so as to transmit data to the second media processing module via the second transmission platform.
[0092] As shown in FIG. 14, FIG. 14 is a flowchart of a data transmission method according to another embodiment of the present application, which may be applied to a second new radio base station, such as the second new radio base station in the NR-DC architecture shown in FIG. 1, and which may include, but is not limited to, steps S910, S920, S930, and S940.
[0093] Step S910: Receive control signaling sent by the first new radio base station, where the control signaling includes target identification information generated by the first new radio base station according to a deployment configuration between the first new radio base station and the second new radio base station.
[0094] The target identification information may be the ID of the first operation processing module of the first new radio base station, a message related to the virtual Stream Control Transmission Protocol (SCTP), a message related to SCTP, or other messages, but is not particularly limited here.
[0095] It should be noted that the second new radio base station can receive the control command via the XN interface, the logical XN interface, or the internal interface, but this is not particularly limited.
[0096] Step S920: Create a second media processing module according to the control signaling.
[0097] In this step, since the control signaling sent by the first new radio base station is received in step S910, upon receiving the control signaling, the second new radio base station creates a second media processing module according to the control signaling, so as to use the second media processing module to perform data offloading in the next step.
[0098] It should be noted that the second media processing module is generated after the second operation processing module of the second new radio base station receives the control signaling, but is not particularly limited here.
[0099] Step S930: Determine a deployment mode between the second new radio base station and the first new radio base station according to the target identification information.
[0100] Step S940: The second media processing module is controlled to perform data offload processing according to the deployment mode.
[0101] The data offload process is related to the bearer type, which is related to the traffic type, and the bearer type is classified into a split bearer and a radio bearer.
[0102] The target of the data streaming process by the second media processing module may be either the first new radio base station or the second new radio base station, but this embodiment is not particularly limited thereto. For example, the core network first transmits data to the second media processing module, and the second media processing module receives the data and then transmits part of the data to the first media processing module and performs data offload processing on the other part of the data within the second new radio base station, but this embodiment is not particularly limited thereto.
[0103] In this embodiment, by adopting a data transmission method including steps S910 to S940, the second new radio base station receives control signaling sent by the first new radio base station, where the control signaling includes target identification information generated by the first new radio base station according to a deployment mode between the first new radio base station and the second new radio base station, determines a deployment mode between the second new radio base station and the first new radio base station based on the target identification information, creates a second media processing module according to the control signaling, and finally controls the second media processing module to perform data offloading processing according to the deployment mode.
[0104] The first new radio base station may be a low frequency new radio base station or a high frequency new radio base station, but this is not particularly limited here.Similarly, the second new radio base station may be a low frequency new radio base station or a high frequency new radio base station, but this is not particularly limited here.
[0105] In one embodiment, as shown in FIG. 15, step S930 will be described, and step S930 may include, but is not limited to, step S1010.
[0106] Step S1010: If the target identification information is a stream control transport protocol, determine the deployment mode between the second new radio base station and the first new radio base station as an inter-station non-common frame deployment.
[0107] In one embodiment, when the second new radio base station receives the control command sent by the first new radio base station, the second new radio base station generates a second media processing module according to the control command, and the control command includes a stream control transport protocol, so the second new radio base station determines the deployment mode between the second new radio base station and the first new radio base station as inter-station non-common frame deployment according to the stream control transport protocol, but this embodiment is not particularly limited thereto.
[0108] In one embodiment, as shown in FIG. 16, step S930 will be described, and step S930 may include, but is not limited to, step S1110.
[0109] Step S1110: If the target identification information is a virtual stream control transport protocol, determine the deployment mode between the second new radio base station and the first new radio base station as a common frame / non-common logical station deployment.
[0110] In one embodiment, when the second new radio base station receives the control command transmitted by the first new radio base station, the second new radio base station generates a second media processing module according to the control command. In addition, since the control command includes a virtual stream control transport protocol, the second new radio base station determines the deployment mode between the second new radio base station and the first new radio base station as a common frame / non-common logical station deployment according to the virtual stream control transport protocol, but this embodiment is not particularly limited thereto.
[0111] In one embodiment, as shown in FIG. 17, step S930 will be described, and step S930 may include, but is not limited to, step S1210.
[0112] Step S1210: If the target identification information is the identification information of the first operation processing module of the first new radio base station, determine the deployment mode between the second new radio base station and the first new radio base station as common frame-common logical station deployment.
[0113] The identification information of the first operation processing module of the first new radio base station may be the ID of the first operation processing module or other information, but is not particularly limited here.
[0114] In one embodiment, when the second new radio base station receives the control command transmitted by the first new radio base station, the second new radio base station generates a second media processing module according to the control command. In addition, since the control command includes the ID of the first operation processing module, the second new radio base station determines the deployment mode between the second new radio base station and the first new radio base station as a common frame-common logical station deployment according to the ID of the first operation processing module, but this embodiment is not particularly limited thereto.
[0115] The embodiment shown in FIG. 15 belongs to a parallel group of embodiments to the embodiment shown in FIG. 16 and the embodiment shown in FIG. 17, and corresponds to different deployment forms.
[0116] In one embodiment, as shown in FIG. 18, step S940 will be described. This step S940 may further include, but is not limited to, steps S1310 and S1320 if the deployment type is inter-station non-common frame deployment.
[0117] Step S1310: Control the second operation processing module so that the second operation processing module creates a second transmission platform.
[0118] Step S1320: Control the second media processing module so that the second media processing module performs data offload processing via an external network port of the second transmission platform.
[0119] In this embodiment, when the deployment mode of the first new radio base station and the second new radio base station is inter-station non-common frame deployment, the second new radio base station controls the second operation processing module to create a second transmission platform, and the second media processing module performs data offload processing through the external network port of the second transmission platform.
[0120] In one embodiment, as shown in FIG. 19, step S940 will be described. This step S940 may further include, but is not limited to, steps S1410 and S1420 if the deployment type is common frame / common logical station deployment.
[0121] Step S1410: The destination IP address and destination MAC address for data offloading are set in the second media processing module.
[0122] Note that this destination IP address and destination MAC address may be those of the first media processing module of the first new radio base station, or those of the equipment of the second new radio base station, but this embodiment does not particularly limit this.
[0123] Step S1420: The second media processing module is controlled in accordance with the destination IP address and the destination MAC address so that the second media processing module performs data offload processing.
[0124] In this embodiment, when the deployment mode of the first new radio base station and the second new radio base station is common frame-common logical station deployment, the second new radio base station controls the second operation processing module so that the second operation processing module sets the destination IP address and destination MAC address for performing data offload processing, and controls the second media processing module so that the second media processing module performs data offload processing according to the destination IP address and destination MAC address.
[0125] In one embodiment, when the deployment mode of the first new radio base station and the second new radio base station is common frame-common logical station deployment, the second operation processing module sets the destination IP address and destination MAC address for data offloading, enters the destination IP address and destination MAC address in the data header of the target for data offloading, and controls the second media processing module to perform data offloading processing according to the destination IP address and destination MAC address, but this embodiment is not particularly limited to this.
[0126] In one embodiment, as shown in FIG. 20, step S940 will be described. This step S940 may further include step S1510 if the deployment type is common frame / non-common logical station deployment, but is not limited thereto.
[0127] Step S1510: Control the second media processing module so that the second media processing module performs data offload processing via an intranet port of the first transmission platform of the first new radio base station.
[0128] In this embodiment, when the deployment form of the first new radio base station and the second new radio base station is common frame / non-common logic station deployment, the second new radio base station controls the second operation processing module so that the second operation processing module performs data offload processing through the intranet port of the first transmission platform of the first new radio base station.
[0129] The embodiment shown in FIG. 18 belongs to a parallel group of embodiments to the embodiment shown in FIG. 19 and the embodiment shown in FIG. 20, and each corresponds to a different deployment form.
[0130] The data transmission method according to the above embodiment will now be described in detail using a specific example. Example 1
[0131] 21, it is assumed that the first new radio base station is a low-frequency new radio base station 500, the second new radio base station is a high-frequency new radio base station 600, the low-frequency new radio base station 500 includes a first distributed unit 510 and a first centralized unit 520, the high-frequency new radio base station 600 includes a second distributed unit 610 and a second centralized unit 620, the first distributed unit 510 and the first centralized unit 520 are communicatively connected, and the second distributed unit 610 and the second centralized unit 620 are communicatively connected. When the low-frequency new radio base station 500 receives a measurement report from the UE, it performs a dual connection addition with the high-frequency new radio base station 600. First, the low frequency new radio base station 500 creates a first operation processing module 521 in the first collection unit 520, and the first operation processing module 521 obtains the configuration list of the low frequency new radio base station 500 based on the low frequency OAM, and determines whether the gNBID and PLMN of the high frequency new radio base station 600 exist in the configuration list. If they exist, it determines whether the gNBID of the low frequency new radio base station 500 and the gNBID of the high frequency new radio base station 600 match, and whether the PLMN of the low frequency new radio base station 500 and the PLMN of the high frequency new radio base station 600 match. If both the gNBID of the low frequency new radio base station 500 and the gNBID of the high frequency new radio base station 600, and the PLMN of the low frequency new radio base station 500 and the PLMN of the high frequency new radio base station 600 match, it determines the low frequency new radio base station 500 and the high frequency new radio base station 600 as a common frame common logical station deployment. Then, the first operation processing module 521 configures the first transmission platform 530 and creates a first media processing module in the first centralization unit 520. The first operation processing module 521 sends an SN Addition Request request message to the second operation processing module 621 of the high frequency new radio base station 600 via the first transmission platform 530, and a control signaling including the ID information of the first operation processing module 521 is added to the SN Addition Request request message.Upon receiving the request, the second operation processing module 621 generates a second media processing module 622 in the second centralized unit 620 and returns an SN Addition Request Response message to the first operation processing module 521. The second operation processing module 521 obtains the ID information of the first operation processing module 521 from the control signaling. The second operation processing module 521 may directly send a message including the ID information of the second operation processing module 521 to the first operation processing module 521 based on the ID information of the first operation processing module 521. Upon receiving the message including the ID information of the second operation processing module 621, the first operation processing module 521 can obtain the ID information of the second operation processing module 621. Thereafter, the first operation processing module 521 and the second operation processing module 621 can communicate with each other through each other's ID information. When the first media processing module 522 receives the notification of backtransmission of data, the first operation processing module 521 sets the IP address and MAC address of the second media processing module 622 in the first media processing module 522, and the first media processing module 522 then directly writes the IP address and MAC address in the data header of the backtransmitted data and sends it to the second media processing module 622 via the first transmission platform 530. From the user's perspective, this example adopts a dual-master, dual-instance approach and employs different transmission methods depending on the deployment scenario, thereby reducing the latency of the NR-DC process and data transmission and improving user perception.
[0132] Both the first operation processing module 521 and the second operation processing module 621 send messages via the XN interface, and these messages undergo ASN.1 (Abstract Syntax Notation Number one) encoding. Example 2
[0133] This example and the above example are based on the same structural diagram. Referring to Figure 21, it is assumed that the first new radio base station is a low-frequency new radio base station 500, the second new radio base station is a high-frequency new radio base station 600, the low-frequency new radio base station 500 includes a first distributed unit 510 and a first centralized unit 520, the high-frequency new radio base station 600 includes a second distributed unit 610 and a second centralized unit 620, the first distributed unit 510 and the first centralized unit 520 are communicatively connected, and the second distributed unit 610 and the second centralized unit 620 are communicatively connected. When the low-frequency new radio base station 500 receives a measurement report from the UE, it performs a dual connection addition with the high-frequency new radio base station 600. First, the low-frequency new radio base station 500 creates a first operation processing module 521 in the first collection unit 520, and the first operation processing module 521 obtains the configuration list of the low-frequency new radio base station 500 based on the low-frequency OAM, and determines whether the gNBID and PLMN of the high-frequency new radio base station 600 exist in the configuration list. If so, determines whether the gNBID of the low-frequency new radio base station 500 matches the gNBID of the high-frequency new radio base station 600, and whether the PLMN of the low-frequency new radio base station 500 matches the PLMN of the high-frequency new radio base station 600. However, if the gNBID of the low frequency new radio base station 500 does not match the gNBID of the high frequency new radio base station 600, or the PLMN of the low frequency new radio base station 500 does not match the PLMN of the high frequency new radio base station 600, or both the gNBID of the low frequency new radio base station 500 and the gNBID of the high frequency new radio base station 600 and the PLMN of the high frequency new radio base station 500 do not match, the low frequency new radio base station 500 and the high frequency new radio base station 600 are determined to be in a common frame / non-common logical station deployment. Then, the first operation processing module 521 configures the first transmission platform 530 and creates a first media processing module 522 in the first centralization unit 520.The first media processing module 522 sends an SN Addition Request message to the second operation processing module 621 of the high-frequency new radio base station 600 via the intranet port of the first transmission platform 530. Control signaling including a virtual stream control transport protocol is added to the SN Addition Request message. The control signaling is sent to the logical XN interface and then sent to the second operation processing module 621 of the high-frequency new radio base station 600 via the logical XN interface. Upon receiving the control signaling, the second operation processing module 621 generates a second media processing module 622 in the second centralization unit 620 and returns an SN Addition Request Response message to the first operation processing module 521. The second operation processing module 621 obtains the virtual stream control transport protocol from the control signaling and determines from the virtual stream control transport protocol that the high-frequency new radio base station 600 and the low-frequency new radio base station 500 are in a common frame / non-common logical station deployment. The first operation processing module 521 and the second operation processing module 621 can then communicate via the virtual stream control transport protocol. When the first media processing module 522 receives the notification of backhaul data, the first operation processing module 521 sets the IP address of the second media processing module 622 to the first media processing module 522. The first media processing module 522 then directly writes the IP address in the data header of the backhauled data and sends it to the second media processing module 622 via the intranet port of the first transmission platform 530. From the perspective of the carrier, this example saves the carrier's physical resources and reduces the SCTP link between the transmission resources and IP resources and the 5GC by half, significantly reducing the carrier's maintenance costs and improving base station performance.From the user's perspective, adopting dual-master and dual-instance aspects and adopting different transmission methods depending on the deployment scenario reduces the delay in NR-DC processes and data transmission, improving user perception.
[0134] Both the first operation processing module 521 and the second operation processing module 621 send messages via the XN interface, and these messages undergo ASN.1 (Abstract Syntax Notation Number one) encoding. Example 3
[0135] 22, it is assumed that the first new radio base station is a low-frequency new radio base station 500, the second new radio base station is a high-frequency new radio base station 600, the low-frequency new radio base station 500 includes a first distributed unit 510 and a first centralized unit 520, the high-frequency new radio base station 600 includes a second distributed unit 610 and a second centralized unit 620, the first distributed unit 510 and the first centralized unit 520 are communicatively connected, and the second distributed unit 610 and the second centralized unit 620 are communicatively connected. When the low-frequency new radio base station 500 receives a measurement report from the UE, it performs a dual connection addition with the high-frequency new radio base station 600. First, the low-frequency new radio base station 500 creates a first operation processing module 521 in the first collection unit 520. The first operation processing module 521 obtains a configuration list of the low-frequency new radio base station 500 based on the low-frequency OAM, determines whether the gNBID and PLMN of the high-frequency new radio base station 600 are present in the configuration list, and if not, determines the low-frequency new radio base station 500 and the high-frequency new radio base station 600 as an inter-station non-common frame deployment. Next, the first operation processing module 521 configures the first transmission platform 530, creates a first media processing module 522 in the first centralization unit 520, and sends an SN Addition Request message to the second operation processing module 621 of the high-frequency new radio base station 600 via the external network port of the first transmission platform 530. Control signaling including a stream control transport protocol is added to this SN Addition Request message. The control signaling is transmitted to the XN interface and then transmitted via the XN interface to the second transmission platform 630 of the high frequency new radio base station 600. The second transmission platform 630 transmits the control signaling including the stream control transport protocol to the second operation processing module 621.Upon receiving the control signaling, the second operation processing module 621 generates a second media processing module 622 in the second centralization unit 620 and returns an SN Addition Request Response message to the first operation processing module 521. The second operation processing module 621 obtains the stream control transport protocol from the control signaling and determines that the high frequency new radio base station 600 and the low frequency new radio base station 500 are in inter-station non-common frame deployment according to the stream control transport protocol. Then, the first operation processing module 521 and the second operation processing module 621 can communicate via the stream control transport protocol. When the first media processing module 522 receives the notification of data backhaul, the first operation processing module 521 sets the IP address of the second media processing module 622 to the first media processing module 522. The first media processing module 522 then directly writes the IP address in the data header of the backhauled data, sends it to the second transmission platform 630 via the external network port of the first transmission platform 530, and then sends it to the second media processing module 622 via the second transmission platform 630. From the carrier's perspective, this saves the carrier's physical resources and halves the SCTP links between the transmission resources and IP resources and the 5GC, significantly reducing the carrier's maintenance costs and improving base station performance. From the user's perspective, adopting a dual-master, dual-instance approach and employing different transmission methods depending on the deployment scenario reduces the latency of NR-DC processes and data transmission, improving user perception.
[0136] Both the first operation processing module 521 and the second operation processing module 621 send messages via the XN interface, and these messages undergo ASN.1 (Abstract Syntax Notation Number one) encoding.
[0137] There are various ASN.1 encoding formats, such as Basic Encoding Rules (BER), Canonical Encoding Rules (CER), and Distinguished Encoding Rules (DER), of which BER, CER, and DER are the three most common ASN.1 encoding formats.
[0138] In the above three examples, i.e., Example 1 and Example 2 shown in FIG. 21 and Example 3 shown in FIG. 22, from the perspective of device manufacturers, in the NR-DC, different operation processing modules, such as the first operation processing module 521 and the second operation processing module 621, are installed on the CU side (first centralized unit or second centralized unit). For example, the first operation processing module 521 and the second operation processing module 621 can be directly ported to three deployment scenarios: inter-station non-common frame deployment, common frame-common logical station deployment, and common frame-non-common logical station deployment, eliminating the need for redevelopment. The media plane employs an independent media plane instance method, eliminating the need for redevelopment and enabling direct porting to the three deployment scenarios. This significantly reduces implementation complexity, allows the same software version to flexibly adapt to the three deployment scenarios, and saves labor and maintenance costs.
[0139] In the above three examples, i.e., Example 1 and Example 2 shown in Figure 21, and Example 3 shown in Figure 22, the frequency range corresponding to the low-frequency new radio base station 500 may be 450 MHZ to 6000 MHZ, and the frequency range corresponding to the high-frequency new radio base station 600 may be 24250 MHZ to 52600 MHZ, but this is not particularly limited here.
