Description

[0002] The current 3GPP (3rd Generation Partnership Project) standard only supports terminals connecting to ground base stations via satellites in transparent mode. Therefore, only satellite identification information is transmitted for the backhaul architecture. However, to overcome the problem of geographical limitations on communication services, it is necessary to integrate ground base stations with satellites in regenerative mode to provide a series of value-added services for terminals.

[0003] Traditional methods for transmitting satellite identification information primarily focus on the satellite identification of the satellite corresponding to the UPF (User Plane Function) in the backhaul architecture. Therefore, interaction is limited to the AMF (Access and Mobility Management Function) and SMF (Session Management Function). The AMF pre-configures the association between wireless side information and satellite backhaul information. This allows it to determine the satellite identification of a high-orbit satellite when the backhaul type is a high-orbit satellite, and transmits this information to the SMF. Based on this pre-configuration, the SMF maps the satellite identification information to a data network access identifier to select the appropriate user plane for the user.

[0047] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0050] AMF: Access and Mobility Management Function, access and mobility management function;

[0052] UPF: User Plane Function, user plane function;

[0053] N2 interface: reference point between (R)AN and AMF;

[0054] N11 interface: reference point between SMF and AMF.

[0055] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0056] In an exemplary embodiment, Figure 2 As shown, a method for transmitting satellite identification information is provided, which is applied to Figure 1 The SMF in the example is used to illustrate the process, which includes the following steps:

[0057] Step 202: Receive a session creation context request message or a session update context request message sent by the AMF.

[0058] The session creation context request message and the session update context request message include the regeneration mode satellite identification information of the terminal.

[0059] In implementation, in regeneration mode, the AMF sends the regeneration mode satellite identification information to the SMF through the session creation context request message (Nsmf_PDUSession_CreateSMContext Request message) or the session update context request message (Nsmf_PDUSession_UpdateSMContext Request message). The SMF receives the session creation context request message or the session update context request message sent by the AMF, thereby obtaining the regeneration mode satellite identification information of the user terminal.

[0060] Step 204: Deliver the regeneration mode satellite identification information to the PCF.

[0061] During implementation, the SMF transmits the regeneration mode satellite identification information to the PCF, enabling the PCF to perform customized traffic control based on the regeneration mode satellite identification information. For example, the PCF can provide this regeneration mode satellite identification information to the AF, enabling the AF to identify and classify user traffic and dynamically adjust user routing paths to meet different service requirements. There are various specific methods for the SMF to transmit the regeneration mode satellite identification information to the PCF, which will be further described in the following embodiments and are not detailed here.

[0062] In the above-described method for transmitting satellite identification information, a session creation context request message or a session update context request message sent by the AMF is received; the session creation context request message or the session update context request message includes the terminal's regeneration mode satellite identification information; and the regeneration mode satellite identification information is transmitted to the PCF. This method enables the transmission of satellite identification information in regeneration mode. The AMF can transmit the regeneration mode satellite identification information to the SMF, and then transmit it to the PCF via the SMF, so that the PCF can conduct user sessions based on the regeneration mode satellite identification information.

[0063] In an exemplary embodiment, a specific method is provided in which the SMF transmits the regeneration mode satellite identification information to the PCF. The specific processing of step 204 may include:

[0064] Step 2041: When requesting the PCF to create an SM policy association corresponding to the PDU session, the regeneration mode satellite identification information is passed to the PCF.

[0065] In implementation, the SM policy is specifically used to manage and control network sessions (e.g., PDU sessions). Therefore, when the SMF requests the PCF to create an SM policy association corresponding to a PDU (Protocol Data Unit) session, the SMF passes the regeneration mode satellite identification information to the PCF to implement the application of the satellite identification information by the PCF in the regeneration mode.

[0066] In this embodiment, the SMF transmits the regeneration mode satellite identification information to the PCF, thereby supporting the user terminal in the regeneration mode satellite access network architecture to communicate with another user terminal via the satellite, thereby realizing the transmission of the regeneration mode satellite identification information.

[0067] In an exemplary embodiment, the specific processing of step 204 may include:

[0068] Step 2042: When the regeneration mode satellite identification information changes, the updated regeneration mode satellite identification information is delivered to the PCF by requesting an update of the SM policy association.

[0069] In implementation, when the regeneration mode satellite identification information changes, the SMF promptly updates the regeneration mode satellite identification information on the PCF side. Therefore, the SMF transmits the updated regeneration mode satellite identification information to the PCF by requesting an update of the SM policy association.

[0070] In this embodiment, when the regeneration mode satellite identification information changes, the SMF transmits the updated regeneration mode satellite identification information to the PCF side through the update of the SM policy association, ensuring the timeliness and effectiveness of the update of the regeneration mode satellite identification information on the PCF side.

[0071] In an exemplary embodiment, a method for transmitting satellite identification information is provided. Figure 1 The AMF in the example is used to illustrate, including the following steps:

[0072] Step 201: When a terminal accesses a wireless access network node and triggers a service request, session establishment or modification request, a session creation context request message or a session update context request message is sent to the SMF.

[0073] The session creation context request message and the session update context request message contain the terminal's regeneration mode satellite identification information, which is then passed to the PCF via the SMF for use in the user session.

[0074] In implementation, during the transmission of regenerative mode satellite identification information, the radio access network node may proactively transmit the regenerative mode satellite identification information to the AMF, or the AMF may determine the regenerative mode satellite identification information when the terminal triggers a service request, session establishment, or modification request. The AMF determines the regenerative mode satellite identification information in any of the aforementioned situations. When the terminal accesses the radio access network node and triggers a service request, session establishment, or modification request, the AMF, in response to any of the aforementioned requests, transmits the regenerative mode satellite identification information to the SMF, which then transmits the regenerative mode satellite identification information to the PCF, thereby enabling applications such as user terminal communication in the regenerative mode satellite access network architecture.

[0075] In this embodiment, when the terminal accesses the wireless access network node and triggers a service request, session establishment or modification request, the AMF can transmit the satellite identification information in the regeneration mode to the SMF, and transmit it to the PCF through the SMF, so that the PCF can conduct a user session based on the satellite identification information in the regeneration mode.

[0076] In an exemplary embodiment, the specific processing of step 201 includes:

[0077] Step 2011: Determine that the current terminal is accessing a satellite in regeneration mode, and send the identification information of the regeneration mode satellite accessed by the current terminal in a session creation context request message or a session update context request message to the SMF.

[0078] In implementation, when it is determined that the current user terminal UE is accessing the satellite in regeneration mode, the SMF will carry the identification information of the regeneration mode satellite accessed by the current UE in the session creation context request (i.e., Nsmf_PDUSession_CreateSMContext Request) message or the session update context request (i.e., Nsmf_PDUSession_UpdateSMContext Request) message and send it to the SMF. Specifically, the AMF will pass the regeneration mode satellite identification information of the user terminal transmitted in the Nsmf_PDUSession_CreateSMContext Request message or the Nsmf_PDUSession_UpdateSMContext Request message to the SMF through the N11 interface.

[0079] In this embodiment, the regeneration mode satellite identification information is transmitted to the SMF through the AMF, so that the regeneration mode satellite identification information can be distributed and transmitted in the mobile network. The SMF message can obtain the real-time position, status and other information of the regeneration mode satellite accessed by the user terminal based on the regeneration mode satellite identification information, thereby avoiding the connection uncertainty problem caused by satellite movement, and selecting, modifying, adding and releasing UPF for the user session.

[0080] There are multiple methods for transmitting the regeneration mode satellite identification information from the wireless network side (for example, the wireless access network node) to the AMF. In the embodiments of the present application, the transmission methods of the regeneration mode satellite identification information between the wireless network side and the AMF are introduced respectively. Therefore, in an exemplary embodiment, the transmission method of the satellite identification information further includes:

[0081] Step 200a: Receive an NG establishment request message sent by a wireless access network node.

[0082] The NG establishment request message carries the regeneration mode satellite identification information.

[0083] In practice, the radio network side can pass the regeneration mode satellite identification information to the AMF through the NG Setup Request message at the beginning of base station establishment. For example, if the radio access network node is a base station (gNB), the base station sends an NG Setup Request message over the N2 interface. The NG Setup Request message carries the regeneration mode satellite identification information. Therefore, the AMF can obtain the regeneration mode satellite identification information through the NG Setup Request message.

[0084] In this embodiment, by sending an NG establishment request message on the wireless network side, the regeneration mode satellite identification information is passed to the AMF side at the beginning of the base station establishment, thereby enhancing the communication process under the network architecture of the regeneration mode satellite access, thereby enabling the regeneration mode satellite identification information to be distributed and transmitted in the mobile network.

[0085] In another exemplary embodiment, for a process in which a wireless network side (e.g., a wireless access network node) transmits regeneration mode satellite identification information to an AMF, the method for transmitting the satellite identification information further includes:

[0086] Step 200b: Receive a radio access network configuration update message sent by a radio access network node.

[0087] The radio access network configuration update message carries the regeneration mode satellite identification information.

[0088] In implementation, when the network configuration information in a radio access network node is updated, the regeneration mode satellite identification information therein is also updated. Therefore, the radio access network node (e.g., a gNB) sends a Radio Access Network Configuration Update (RAN CONFIGURATION UPDATE) message to the AMF. This RAN CONFIGURATION UPDATE message carries the updated regeneration mode satellite identification information. Therefore, after the AMF confirms the successful update, the regeneration mode satellite identification information received by the AMF in the RAN CONFIGURATION UPDATE message is the updated regeneration mode satellite identification information.

[0089] In this embodiment, when the network configuration information in the wireless access network node is updated, the updated regeneration mode satellite identification information is transmitted to the AMF side by sending a wireless access network configuration update message on the wireless network side, thereby enhancing the communication process under the network architecture of the regeneration mode satellite access and ensuring the timeliness and effectiveness of the update of the regeneration mode satellite identification information.

[0090] In an exemplary embodiment, the method for the AMF to determine the regeneration mode satellite identification information of the terminal, in addition to being transmitted through the wireless network side, can also be determined by the AMF side based on a locally pre-configured association relationship. Therefore, before sending the session creation context request message or the session update context request message to the SMF in step 201, the method for transmitting the satellite identification information further includes:

[0091] Step 201b: Determine the regeneration mode satellite identification information corresponding to the terminal in the pre-configured association relationship between the wireless access network node and the regeneration mode satellite identification information.

[0092] In implementation, the AMF pre-configures the association between the radio access network node and the regeneration mode satellite identification information locally. Therefore, when a terminal accesses through the radio access network node and triggers a service request, session establishment, or modification request, the AMF can determine the regeneration mode satellite identification information of the currently connected terminal based on the pre-configured association. For example, as shown in Table 1 below, Table 1 shows the association between the radio access network node and the regeneration mode satellite identification information.

[0093] Table 1

[0094]

[0095] Among them, Global RAN node ID_1 represents the first radio access network node, Global RAN node ID_2 represents the second radio access network node, and Reg_Satellite ID_1 represents the first regenerative mode satellite identification information. The association relationship in Table 1 shows that the first radio access network node and the second radio access network node access the same regenerative mode satellite. Therefore, these two radio access network nodes correspond to the same regenerative mode satellite identification information.

[0096] In this embodiment, the regeneration mode satellite identification information corresponding to the terminal is determined through a pre-configured association relationship, so that the wireless access network node can better optimize network resources and enable the SMF to select a more appropriate UPF for the user session.

[0097] In an exemplary embodiment, the method further includes:

[0098] Step 201c: When the wireless access network node accessed by the terminal changes, the updated regeneration mode satellite identification information of the terminal is determined, and the updated regeneration mode satellite identification information is transmitted to the SMF.

[0099] During implementation, when the wireless access network node accessed by the terminal changes, that is, after the terminal re-accesses the new wireless access network node, the AMF needs to update the regeneration mode satellite identification information corresponding to the terminal. Specifically, the AMF updates the regeneration mode satellite identification information corresponding to the terminal. It can be determined by pre-configured association between the local wireless access network node and the regeneration mode satellite identification information (the above step 201b), or the wireless access network node transmits the updated regeneration mode satellite identification information to the AMF through the N11 interface (this process has been described in the above step 200a or 200b and will not be repeated here). This embodiment of the present application does not limit this.

[0100] After the AMF determines the updated regeneration mode satellite identification information of the terminal, the AMF transmits the updated regeneration mode satellite identification information to the SMF. The process of the AMF transmitting the regeneration mode satellite identification information to the SMF has been described in step 201 or step 2011 above and will not be repeated here.

[0101] In this embodiment, by determining the updated regeneration mode satellite identification information of the terminal and transmitting it to the SMF, network switching, session management and traffic routing can be better managed, so as to provide more personalized services.

[0102] In an exemplary embodiment, Figure 3 As shown, a specific example process of a method for transmitting satellite identification information is provided, and the example process includes the following steps:

[0103] In step 301, the RAN-side base station (gNB) sends an NG Setup Request message to the AMF, where the NG Setup Request message carries the identification information of the satellite in regeneration mode. Alternatively, the RAN-side base station (gNB) sends a RAN Configuration Update message to the AMF, where the RAN Configuration Update message carries the identification information of the satellite in regeneration mode.

[0104] Step 302: When a terminal accesses a wireless access network node and triggers a service request, session establishment or modification request, the regeneration mode satellite identification information corresponding to the terminal is determined in the pre-configured association relationship between the wireless access network node and the regeneration mode satellite identification information.

[0105] In step 303, the AMF sends the identification information of the regeneration mode satellite to which the current terminal is connected, which is carried in the session creation context request (Nsmf_PDUSession_CreateSMContextRequest) message or the session update context request (Nsmf_PDUSession_UpdateSMContextRequest) message, to the SMF.

[0106] Step 304: When requesting the PCF to create an SM policy association corresponding to the PDU session (Npcf_SMPolicyControl_Create Request), the regeneration mode satellite identification information is passed to the PCF; or, when the regeneration mode satellite identification information changes, the updated regeneration mode satellite identification information is passed to the PCF by requesting an update of the SM policy association (Npcf_SMPolicyControl_Update Request).

[0107] It should be understood that although Figures 2 to 3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figures 2 to 3 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The order of execution of these steps or stages is not necessarily one by one, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
