Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and related equipment for indicating high-speed movement. Background Technology

[0002] In current communication systems, base stations exchange their attributes and configuration capabilities through inter-base station interfaces (in 5G communication systems, base stations exchange them through the Xn interface). However, there is no interaction regarding specific cell characteristics. This results in the inability to achieve destination cell mobility control for user equipment with different UE capabilities, and the following problems exist:

[0003] 1) Lack of cell attribute interaction: Currently, only cell PCI, frequency point, PLMN and other information are exchanged between base stations. However, operators that support ATG, UAV and other cells use the same frequency configuration method, which lacks attribute relationships. This will make it impossible to switch the right user equipment to the right cell, resulting in handover failure or interference.

[0004] 2) Unable to determine the additional transmit power and additional spurious values ​​of neighboring cells: The current communication protocol defines that a cell can allow UAV / ATG user equipment to use different transmit powers, but how to obtain this information from neighboring cells? The current solution is to use OMC configuration, which cannot be obtained through automatic configuration. Furthermore, it is also impossible to obtain the configuration of the additional transmit power and additional spurious values ​​of neighboring cells in order to broadcast them in the broadcast message.

[0005] 3) In the CU / DU separation architecture, the CU may not know whether the DU supports the relevant capability configuration, which may lead to incorrect scheduling or admission policies: SIB1 and other information in the message from DU to CU are not mandatory, so the CU may not know whether the DU supports the high-speed mobile cell capability. Therefore, it may misconfigure or refuse the access of user equipment for initial access or handover.

[0006] 4) Unable to obtain relevant configuration information of neighboring cells through the terminal: The current ANR mechanism cannot read information such as the type, transmit power, and spectrum radiation of neighboring cells through measurement and reporting. Therefore, it is not possible to configure directly without an interface.

[0007] Analysis shows that current communication protocols cannot identify whether neighboring cells or separate entities support high-speed mobility. Therefore, providing an indication method to obtain relevant information about neighboring cells is crucial for network deployment and optimization.

[0008] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0068] 3GPP: 3rd Generation Partnership Project.

[0069] NR: New Radio.

[0070] UAV: Unmanned Aerial Vehicle, also known as drone.

[0071] ATG: Air-to-Ground, is a communication technology that allows aircraft to communicate with ground communication networks.

[0073] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0074] Figure 1 A schematic diagram of an exemplary application system architecture is shown, illustrating an application of the indication method supporting high-speed movement as described in the embodiments of this disclosure. For example... Figure 1 As shown, the system architecture includes: a first base station 10, a second base station 20, and a terminal 30.

[0075] It should be noted that the first base station 10 and the second base station 20 in this embodiment can be base stations using any communication protocol, including but not limited to 4G, 5G, and 6G communication protocols. In this embodiment, a base station refers to an access network device that connects a terminal to the core network. It can be a terrestrial network access network device or a non-terrestrial network access network device. In some other scenarios, a base station can also be referred to as a relay, access point, etc. This embodiment does not limit the specific type of base station.

In specific implementations, the terminal may be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device, etc. This embodiment does not limit the specific type of terminal.

[0078] Under the above system architecture, this disclosure provides a method for indicating high-speed movement, which can be executed by any electronic device with computing power.

[0079] In some embodiments, the high-speed mobility indication method provided in this disclosure can be executed by a base station (first base station or second base station) of the above-described system architecture; in other embodiments, the high-speed mobility indication method provided in this disclosure can be executed by a terminal in the above-described system architecture; in still other embodiments, the high-speed mobility indication method provided in this disclosure can be implemented by the base station and the terminal in the above-described system architecture through interaction.

[0080] For base stations employing a CU and DU separation architecture, the high-speed mobility indication method provided in this embodiment can also be executed by the CU of the base station, or by the CU, DU and terminal of the base station through interactive means.

[0081] 5G is the fifth generation of mobile communication technology. Compared with previous generations of mobile communication technology, it supports high speed, low latency, massive connectivity, high reliability, network slicing and other functions. These features make 5G an important infrastructure to promote digital transformation and will profoundly affect many fields such as industry, transportation, healthcare, and entertainment. Figure 2 This illustration shows a schematic diagram of a 5G communication system architecture according to an embodiment of the present disclosure, such as... Figure 2 As shown, 5G radio nodes (NG-RAN nodes) include at least one of the following two types:

[0082] 1) gNB: User equipment functions that provide NR (New Radio) user plane and control plane protocols for user equipment (UE);

[0083] 2) ng-eNB: Provides user equipment functions for user equipment (UE) that include E-UTRA (Enhanced Universal Terrestrial Radio Access) user plane and control plane protocols.

[0084] gNB and ng-eNB interconnect with each other via the Xn interface. In addition, gNB and ng-eNB connect to the 5G core network (5GC) via the NG interface, connect to AMF (Access and Mobility Management Functions) network elements via the NG-C interface, and connect to UPF (User Plane Functions) network elements via the NG-U interface.

[0085] Figure 3This diagram illustrates a base station with a separate architecture according to an embodiment of the present disclosure. When the base station supports the CU / DU separate architecture, the base station includes: gNB-CU-CP (centralized unit control plane), gNB-CU-UP (centralized unit user plane), and gNB-DU (separated unit). The NG-RAN of a 5G communication system can consist of a group of ng-eNBs. One ng-eNB may contain one ng-eNB-CU-CP, one or more ng-eNB-CU-UPs, and one or more ng-eNB-DUs. The ng-eNB-CU-CP and ng-eNB-CU-UP are connected via an E1 interface. The ng-eNB-DU is connected to the ng-eNB-CU-CP via a W1-C interface and to the ng-eNB-CU-UP via a W1-U interface. One gNB may contain one gNB-CU-CP, multiple gNB-CU-UPs, and multiple gNB-DUs. Among them, gNB-CU-CP is connected to gNB-DU through F1-C interface; gNB-CU-UP is connected to gNB-DU through F1-U interface; gNB-CU-UP is connected to gNB-CU-CP through E1 interface; one gNB-DU can only be connected to one gNB-CU-CP; one gNB-CU-UP can only be connected to one gNB-CU-CP.

[0086] To enhance the reliability of the communication system, a gNB-DU and / or gNB-CU-UP can be connected to multiple gNB-CU-CPs. A gNB-DU can also be connected to multiple gNB-CU-UPs under the control of the same gNB-CU-CP; similarly, a gNB-CU-UP can be connected to multiple gNB-DUs under the control of the same gNB-CU-CP. The connection between gNB-CU-UPs and gNB-DUs is established by the gNB-CU-CP using Bearer Context Management. The gNB-CU-CP selects the appropriate gNB-CU-UP based on the service required by the UE. If multiple CU-UPs exist and belong to the same security domain, data forwarding between gNB-CU-UPs can be supported via the Xn-U interface during intra-gNB handover within a gNB.

[0087] The 5G communication system (hereinafter referred to as the 5G system) supports air communication technology and aviation communication ATG technology in the R18 stage. It not only supports NR connection of UE that can carry out air communication, but also supports HSDN for high-speed mobile scenarios (such as mobile scenarios to support high-speed rail).

[0088] In 5G communication systems, nr-NS-PmaxList is a parameter defined in the 3GPP technical specifications that relates to the maximum power level of non-serving carriers. Specifically, nr-NS-PmaxList is a set of parameters describing the maximum transmit power list (nr-NS-PmaxList) and additional spectrum emission limits that a user equipment (UE) can use on a non-serving carrier. Each entry in this list corresponds to a frequency band and includes the maximum transmit power limit (P_max) and additional spectrum emission limit for the non-serving carrier to meet network requirements for spectrum usage.

[0089] Figure 4 This diagram illustrates a process for establishing an interface connection between a separate base station entity and a centralized base station entity according to an embodiment of this disclosure. Figure 4 As shown, in a 5G communication system, the base station decoupling entity sends an F1 interface establishment request message to the base station central entity, and the base station central entity returns an F1 interface establishment response message to the base station decoupling entity, thus completing the establishment of the F1 interface between the base station decoupling entity and the base station central entity. The F1 interface can now be used for user data transmission and control information exchange. The design of the F1 interface allows for more flexible network slicing and more efficient traffic management, which is crucial for supporting various new 5G applications and services, such as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). Successful establishment of the F1 interface is a critical part of the normal operation of the 5G network, ensuring effective communication between the user plane and the control plane.

[0090] Figure 5 This illustration shows a flowchart of a high-speed mobility indication method applied to a base station side according to an embodiment of the present disclosure, such as... Figure 5 As shown, the method includes the following steps:
