[0119] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0120] Figure 1 This is a schematic diagram illustrating an application scenario for a method for determining onboard communication services provided in an embodiment of this application. For example... Figure 1 As shown, in this scenario, the first device 100 and the second device 200 transmit data via one or more serving satellites 300. Under the coverage of these satellites, the data exchanged between the first device 100 and the second device 200 enables on-board communication without traversing a terrestrial network. Specifically, the first IP Multimedia Subsystem (IMS) network provides voice services to the first device 100, and the second IMS network provides voice services to the second device 200. Typically, network elements in the IMS network may include Proxy-Call Session Control Function (P-CSCF) elements and Serving Call Session Control Function (S-CSCF) elements. The P-CSCF element connects to the user equipment layer and is responsible for receiving and forwarding messages, implementing resource authorization and QoS management. The S-CSCF element controls user registration and authentication, sessions, and records call status. It should be noted that, in the embodiments of this application, the first P-CSCF network element can be the calling side network element and the second P-CSCF network element can be the called side network element; or, the first P-CSCF network element can be the called side network element and the second P-CSCF network element can be the calling side network element. The embodiments of this application do not impose any restrictions here.

[0121] In order to enable UE-satellite-UE communication to support IMS voice services, the IMS network needs to determine the access information of both parties in the call to determine whether IMS voice services can be provided in the UE-satellite-UE communication mode.

[0122] Based on the aforementioned traditional technologies, this application provides a method for determining on-board voice service. When a first P-CSCF network element of a first IMS network serving a first device determines that the first device is in regenerative mode satellite access, it can send a first Session Initiation Protocol (SIP) message. The first SIP message includes the first regenerative mode satellite access information of the first device. The first P-CSCF network element can send out this information, enabling a second P-CSCF network element receiving the first SIP message to determine, based on the first regenerative mode satellite access information and the second regenerative mode satellite access information of the second device served by the second P-CSCF network element, whether to provide on-board voice service for both the first and second devices. This enables the IMS network to obtain the access information of both parties in a call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on this access information.

[0123] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0124] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0125] In one embodiment, such as Figure 2 As shown, a method for determining on-board communication services is provided, which is applied to... Figure 1 Taking the first P-CSCF network element of the first IMS network as an example, the following steps are included:

[0126] S201, if it is determined that the first device is in regenerative mode satellite access, a first session initiation protocol (SIP) message is sent; the first SIP message includes the first regenerative mode satellite access information of the first device.

[0127] First, in this embodiment, the regenerative mode satellite access information of the device will be explained. Optionally, the regenerative mode satellite access information of the device may include at least one of the following: Radio Access Technology Type (RAT type) indicating regenerative mode satellite access, indication information indicating that the device is accessed by regenerative mode satellite, regenerative mode satellite identifier, location information provided by the network, and global cell identifier. That is, the regenerative mode satellite access information of the device may be any one of the following: RAT type indicating regenerative mode satellite access, indication information indicating that the device is accessed by regenerative mode satellite, regenerative mode satellite identifier, location information provided by the network, and global cell identifier. Alternatively, the regenerative mode satellite access information of the device may also be a combination of two or more of the following: RAT type indicating regenerative mode satellite access, indication information indicating that the device is accessed by regenerative mode satellite, regenerative mode satellite identifier, location information provided by the network, and global cell identifier.

[0128] In this embodiment, when the first P-CSCF network element determines that the first device is in regenerative mode satellite access, it sends the first regenerative mode satellite access information of the first device in a first SIP message. Further, the second P-CSCF network element that receives the first SIP message can determine whether to provide on-board communication service for the first device and the second device based on the first regenerative mode satellite access information and the second regenerative mode satellite access information of the second device served by the second P-CSCF network element.

[0129] Optionally, in this embodiment, the first P-CSCF network element can send the first regeneration mode satellite access information of the first device in the P-Access-Network-Info header field of the first SIP message.

[0130] In this embodiment, as an optional implementation, the first P-CSCF network element can send the first regeneration mode satellite access information of the first device to a trusted network element determined by the first P-CSCF network element.

[0131] Optionally, in this embodiment, the first P-CSCF network element can obtain the first regeneration mode satellite access information of the first device by subscription. Optionally, in this embodiment, the method for the first P-CSCF network element to subscribe to the first regeneration mode satellite access information of the first device includes, but is not limited to: notifying when the subscription event occurs and the subscription is valid.

[0132] In the above-mentioned method for determining on-board voice service, when the first P-CSCF network element of the first IMS network serving the first device determines that the first device is in regenerative mode satellite access, it can send a first session initiation protocol (SIP) message. The first SIP message includes the first regenerative mode satellite access information of the first device. The first P-CSCF network element can send out the first regenerative mode satellite access information of the first device, so that the second P-CSCF network element that receives the first SIP message can determine whether to provide on-board voice service for the first device and the second device based on the first regenerative mode satellite access information and the second regenerative mode satellite access information of the second device served by the second P-CSCF network element. This enables the IMS network to obtain the access information of both parties in the call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on the access information of both parties.

[0133] Based on the above embodiments, the first P-CSCF network element can send the first SIP message to the first service session control function S-CSCF network element. The first SIP message triggers the second P-CSCF network element to determine whether to provide on-board communication service to the first and second devices based on the first regeneration mode satellite access information and the second regeneration mode satellite access information of the second device served by the second P-CSCF network element. In one embodiment, S201 includes: sending a first SIP message to the first service session control function S-CSCF network element; the first SIP message is used to trigger the second P-CSCF network element to determine whether to provide on-board communication service to the first and second devices based on the first and second regeneration mode satellite access information; the second regeneration mode satellite access information is the regeneration mode satellite access information of the second device served by the second P-CSCF network element.

[0134] Optionally, in this embodiment, when the first P-CSCF network element determines that the first device is in regenerative mode satellite access, it can send the aforementioned first SIP message to the first S-CSCF network element of the first IMS network. Further, after receiving the aforementioned first SIP message, the first S-CSCF network element can trigger the second P-CSCF network element based on the first SIP message to determine whether to provide on-board communication service for the first device and the second device according to the aforementioned first regenerative mode satellite access information and second regenerative mode satellite access information. The second regenerative mode satellite access information is the regenerative mode satellite access information of the second device served by the aforementioned second P-CSCF network element.

[0135] Optionally, in this embodiment, after receiving the first SIP message, the first S-CSCF network element can send the first SIP message to other network elements in the second IMS network corresponding to the second P-CSCF network element. The other network elements then send the first SIP message to the second P-CSCF network element, triggering the second P-CSCF network element to determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information and the second regeneration mode satellite access information.

[0136] In this embodiment, by sending a first SIP message to the first S-CSCF network element, the first S-CSCF network element can forward the first SIP message to the second P-CSCF network element. The first SIP message triggers the second P-CSCF network element to determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information and the second regeneration mode satellite access information. This enables the IMS network to obtain the access information of both parties in the call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on the access information of both parties.

[0137] This embodiment will describe in detail the process by which the first P-CSCF network element determines whether the first device is a regenerative mode satellite access device. In one embodiment, such as Figure 3 As shown, the above method also includes:

[0138] S301, upon receiving the second SIP message sent by the first device, sends a first query request to the 5G core network.

[0139] Optionally, in this embodiment, the second SIP message can be any one of the SIP messages sent by the first device, such as a registration message, a request message, or a response message.

[0140] In this embodiment, when the first P-CSCF network element receives the second SIP message sent by the first device, it can send a first query request to the 5G core network through the communication connection with the 5G core network, and query the access information of the first device through the first query request.

[0141] S302, based on the first query request, obtain the access information of the first device.

[0142] In this embodiment, after the first P-CSCF network element sends the first query request to the 5G core network, the 5G core network can query the access information of the first device based on the first query request and send the access information of the first device to the first P-CSCF network element, so that the first P-CSCF network element can obtain the access information of the first device based on the first query request.

[0143] S303, Based on the access information of the first device, determine whether the first device is a regenerable mode satellite access.

[0144] In this embodiment, the first P-CSCF network element can determine whether the first device is using regenerative mode satellite access based on the access information of the first device obtained. Optionally, in this embodiment, the first P-CSCF network element can determine whether the first device is using regenerative mode satellite access by determining whether the access information of the first device includes the aforementioned regenerative mode satellite access information. Optionally, if the access information of the first device includes any one or more of the following information: RAT type indicating regenerative mode satellite access, indication information indicating that the first device is using regenerative mode satellite access, regenerative mode satellite identifier, location information provided by the network, and global cell identifier, then the first P-CSCF network element can determine that the first device is using regenerative mode satellite access; if the access information of the first device does not include any one of the following information: RAT type indicating regenerative mode satellite access, indication information indicating that the first device is using regenerative mode satellite access, regenerative mode satellite identifier, location information provided by the network, and global cell identifier, then the first P-CSCF network element can determine that the first device is not using regenerative mode satellite access.

[0145] In this embodiment, when the first P-CSCF network element receives the second SIP message sent by the first device, it can quickly obtain the access information of the first device by sending a first query request to the 5G core network. Based on the first query request, it can quickly determine whether the first device is a regenerable mode satellite access based on the access information of the first device, thereby improving the efficiency of the first P-CSCF network element in determining whether the first device is a regenerable mode satellite access.

[0146] In some scenarios, the first P-CSCF network element can also receive the second regeneration mode satellite access information of the second device, and then determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information of the first device served by the first P-CSCF network element and the received second regeneration mode satellite access information of the second device. In one embodiment, such as Figure 4 As shown, the above method also includes:

[0147] S401 receives satellite access information for the second regeneration mode from the second device.

[0148] In this embodiment, the second regenerative mode satellite access information received by the first P-CSCF network element from the second device may be sent by a network element in the IMS network serving the second device to the first S-CSCF network element, and the first S-CSCF network element forwards the second regenerative mode satellite access information sent by the network element in the second IMS network to the first P-CSCF network element; or, it may be sent directly by the second P-CSCF network element serving the second device to the first P-CSCF network element.

[0149] In addition, in this embodiment, it should be noted that if the first P-CSCF network element receives the second regeneration mode satellite access information of the second device, the first P-CSCF network element can determine that the second device supports UE-satellite-UE service.

[0150] S402, based on the satellite access information of the first regeneration mode and the satellite access information of the second regeneration mode, determine whether to provide on-board communication service for the first device and the second device.

[0151] Optionally, in this embodiment, the first P-CSCF network element can determine whether both the first device and the second device support on-board communication service based on the first regeneration mode satellite access information and the second regeneration mode satellite access information. If it is determined that both the first device and the second device support on-board communication service, on-board communication service is provided for the first device and the second device.

[0152] In this embodiment, since the first P-CSCF network element can receive the second regeneration mode satellite access information of the second device, the first P-CSCF network element can determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information of the first device it serves and the second regeneration mode satellite access information of the second device it receives. This enables the IMS network to obtain the access information of both parties in the call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on the access information of both parties.

[0153] This embodiment will describe in detail the process by which the first P-CSCF network element determines whether to provide on-board communication service to the first device and the second device based on the first regeneration mode satellite access information and the second regeneration mode satellite access information. In one embodiment, the above S402 includes:

[0154] Step A: If, based on the first regeneration mode satellite access information and the second regeneration mode satellite access information, it is determined that the first device and the second device meet the conditions for performing UE-satellite-UE service, then it is determined that on-board communication service will be provided to the first device and the second device.

[0155] The conditions for UE-satellite-UE service are to meet the conditions for on-board communication service between devices. Optionally, in this embodiment, the conditions for UE-satellite-UE service may include at least one of the following: the access type of both the first device and the second device is regenerative mode satellite access; the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable; and the locations of the first device and the second device meet the requirements for providing on-board communication service.

[0156] Optionally, in this embodiment, the first P-CSCF network element can determine whether the access types of the first device and the second device are both regenerative mode satellite access based on the first regenerative mode satellite access information and the second regenerative mode satellite access information; alternatively, it can determine whether the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable based on the first regenerative mode satellite access information and the second regenerative mode satellite access information; or it can determine whether the location of the first device and the second device meets the requirements for providing on-board communication services based on the first regenerative mode satellite access information and the second regenerative mode satellite access information. Further, when the first P-CSCF network element determines that the first device and the second device meet at least one of the following conditions: both the access types of the first device and the second device are regenerative mode satellite access; the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable; or the location of the first device and the second device meets the requirements for providing on-board communication services, it can be determined that on-board communication services can be provided to the first device and the second device.

[0157] In this embodiment, the process by which the first P-CSCF network element determines whether the first device and the second device meet the preset conditions based on the first regeneration mode satellite access information and the second regeneration mode satellite access information is relatively simple. This enables the first P-CSCF network element to quickly determine whether the first device and the second device meet the preset conditions based on the first regeneration mode satellite access information and the second regeneration mode satellite access information, thereby improving the efficiency of the first P-CSCF network element in determining whether to provide on-board communication services for the first device and the second device.

[0158] In one embodiment, such as Figure 5 As shown, a method for determining on-board communication services is provided, which is applied to... Figure 1 Taking the first S-CSCF network element of the first IMS network as an example, the following steps are included:

[0159] S501, determine whether the first device supports satellite communication service.

[0160] Optionally, in this embodiment, the first S-CSCF network element can obtain the first regeneration mode satellite access information of the first device and determine whether the first device supports on-board communication service based on the first regeneration mode satellite access information of the first device. Optionally, in this embodiment, the result determined by the first S-CSCF network element can be that the first device supports on-board communication service, or the result determined by the first S-CSCF network element can be that the first device does not support on-board communication service.

[0161] S502, if it is determined that the first device supports on-board communication service, a third SIP message is sent to the second S-CSCF network element; the third SIP message includes the first regeneration mode satellite access information.

[0162] Optionally, in this embodiment, if the first S-CSCF network element determines that the first device supports on-board communication service, and determines that the second S-CSCF network element is a trusted network element based on the configuration information, then the first S-CSCF network element can send a third SIP message to the second S-CSCF network element. The third SIP message may include the first regeneration mode satellite access information of the first device.

[0163] Furthermore, as an optional implementation, the second S-CSCF network element can send the first regeneration mode satellite access information of the first device to the second P-CSCF network element, triggering the second P-CSCF network element to obtain the second regeneration mode satellite access information of the second device it serves, so that the second P-CSCF network element can determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information and the obtained second regeneration mode satellite access information.

[0164] In this embodiment, the first S-CSCF network element first determines whether the first device supports on-board communication service. If the first device supports on-board communication service, the first S-CSCF network element sends a third SIP message including the first regenerable mode satellite access information to the second S-CSCF network element. This avoids the waste of resources caused by sending the third SIP message to the second S-CSCF network element if the first device does not support on-board communication service.

[0165] This embodiment will explain the triggering timing for the first S-CSCF network element to determine whether the first device supports onboard voice service. In one embodiment, the above S501 includes:

Optionally, the first S-CSCF network element may determine whether the first device supports on-board communication service based on whether the first regeneration mode satellite access information of the first device includes relevant information on supporting on-board communication service.

[0168] In this embodiment, when the first S-CSCF network element receives the first SIP message, it uses the first SIP message as a trigger to determine whether the first device supports satellite communication service. This avoids the problem of resource waste caused by the first S-CSCF network element determining whether the first device supports satellite communication service at any time.

[0169] In this embodiment, the detailed process of the first S-CSCF network element determining whether the first device supports on-board voice service will be described. In one embodiment, such as Figure 6 As shown, the above S501 includes:

[0171] The first configuration file is the configuration file for the satellite communication service of the first device.

[0172] Optionally, in this embodiment, the first S-CSCF network element may store the first configuration file of the first device, and the first S-CSCF network element may obtain the first configuration file of the first device from its own stored file. Alternatively, as another optional implementation, the first S-CSCF network element may send a first acquisition request to other network elements in the first IMS network in which it resides, so that the first S-CSCF network element can obtain the first configuration file of the first device based on the first acquisition request.

[0173] S602, based on the first configuration file, determines whether the first device supports onboard communication service.

[0174] Optionally, in this embodiment, the first S-CSCF network element can obtain relevant information about the satellite communication service from the first configuration file of the first device, and then determine whether the first device supports the satellite communication service based on the obtained information.

[0175] Optionally, in this embodiment, if the first configuration file of the first device includes information related to the satellite communication service of the first device, then the first S-CSCF network element can determine that the first device supports the satellite communication service; if the first configuration file of the first device does not include information related to the satellite communication service of the first device, then the first S-CSCF network element can determine that the first device does not support the satellite communication service.

[0176] In this embodiment, the first S-CSCF network element can accurately determine whether the first device supports satellite call service by obtaining the first configuration file of the first device, thereby ensuring the accuracy of the first S-CSCF network element in determining whether the first device supports satellite call service.

Optionally, in this embodiment, the result determined by the second S-CSCF network element can be that the second device supports on-board communication service, or the result determined by the second S-CSCF network element can be that the second device does not support on-board communication service.

[0180] S702, if it is determined that the second device supports on-board communication service, a fourth SIP message is sent to the second P-CSCF network element; the fourth SIP message includes the first regeneration mode satellite access information of the first device.

[0181] Optionally, in this embodiment, if the second S-CSCF network element determines that the second device supports on-board communication service, it may send a fourth SIP message to the second P-CSCF network element. The fourth SIP message may include the first regeneration mode satellite access information of the first device.

[0182] Furthermore, as an optional implementation, after receiving the aforementioned fourth SIP message, the second P-CSCF network element can be triggered to obtain the second regeneration mode satellite access information of the second device it serves, so that the second P-CSCF network element can determine whether to provide on-board communication service for the first device and the second device based on the aforementioned first regeneration mode satellite access information and the obtained second regeneration mode satellite access information.

[0183] In this embodiment, the second S-CSCF network element first determines whether the second device supports on-board communication service. If the second device supports on-board communication service, it sends a fourth SIP message including the first regeneration mode satellite access information to the second P-CSCF network element. This avoids the waste of resources caused by sending the fourth SIP message to the second S-CSCF network element if the second device does not support on-board communication service.

[0184] This embodiment will describe in detail the process by which the second S-CSCF network element determines whether the second device supports onboard voice service. In one embodiment, S701 includes:

[0186] Optionally, in this embodiment, the second S-CSCF network element may determine whether the second device supports on-board communication service upon receiving the third SIP message sent by the first S-CSCF network element. Alternatively, the second S-CSCF network element may determine whether the second device supports on-board communication service based on whether the second regeneration mode satellite access information of the second device includes relevant information supporting on-board communication service.

[0187] In this embodiment, when the second S-CSCF network element receives the third SIP message sent by the first S-CSCF network element, it uses the third SIP message as a trigger to trigger the second S-CSCF network element to determine whether the second device supports satellite communication service. This avoids the problem of resource waste caused by the second S-CSCF network element determining whether the second device supports satellite communication service at any time.

[0188] In this embodiment, the detailed process of the second S-CSCF network element determining whether the second device supports on-board voice service will be described. In one embodiment, such as... Figure 8 As shown, the above S701 includes:

[0191] Optionally, in this embodiment, the second S-CSCF network element may store the second configuration file of the second device, and the second S-CSCF network element may obtain the second configuration file of the second device from its own stored file. Alternatively, as another optional implementation, the second S-CSCF network element may send a second acquisition request to other network elements in the second IMS network in which it resides, so that the second S-CSCF network element can obtain the second configuration file of the second device based on the second acquisition request.

[0192] S802, based on the second configuration file, determines whether the second device supports onboard communication service.

[0193] Optionally, in this embodiment, the second S-CSCF network element can obtain relevant information about the satellite communication service from the second configuration file of the second device, and thus determine whether the second device supports the satellite communication service based on the obtained information.

[0194] Optionally, in this embodiment, if the second configuration file of the second device includes information related to the satellite communication service of the second device, the second S-CSCF network element can determine that the second device supports the satellite communication service; if the second configuration file of the second device does not include information related to the satellite communication service of the second device, the second S-CSCF network element can determine that the second device does not support the satellite communication service.

[0195] In this embodiment, the second S-CSCF network element can accurately determine whether the second device supports on-board communication service by obtaining the second configuration file of the second device, thereby ensuring the accuracy of the second S-CSCF network element in determining whether the second device supports on-board communication service.

[0196] In one embodiment, such as Figure 9 As shown, a method for determining on-board communication services is provided, which is applied to... Figure 1 Taking the second P-CSCF network element of the second IMS network as an example, the following steps are included:

[0197] S901, receives the fourth SIP message sent by the second S-CSCF network element; the fourth SIP message includes the first regeneration mode satellite access information.

[0198] In this embodiment, after receiving the fourth SIP message sent by the second S-CSCF network element, the second P-CSCF can obtain the first regeneration mode satellite access information of the first device from the fourth SIP message.

[0199] It should be noted that when the second P-CSCF receives the first regeneration mode satellite access information of the first device, it can determine that the first device supports UE-satellite-UE service. That is, when the second P-CSCF receives the fourth SIP message, it can determine that the first device supports UE-satellite-UE service.

[0200] S902, based on the first regeneration mode satellite access information and the second regeneration mode satellite access information, determine whether to provide on-board communication service for the first device and the second device; the second regeneration mode satellite access information is the regeneration mode satellite access information of the second device served by the second P-CSCF network element.

[0201] In this embodiment, the second P-CSCF network element can determine whether to provide on-board communication services for the first device and the second device based on the first regeneration mode satellite access information obtained and the second regeneration mode satellite access information of the second device it serves.

[0202] Optionally, in this embodiment, as an optional implementation, the second P-CSCF network element can send a second query request to the 5G core network to query the second regeneration mode satellite access information of the second device in the 5G core network. This allows the second P-CSCF network element to obtain the second regeneration mode satellite access information of the second device based on the second query request sent to the 5G core network. Further, in this embodiment, as an optional implementation, the second P-CSCF network element can send a second query request to the 5G core network upon receiving the aforementioned fourth SIP message. That is, the second P-CSCF network element can send a second query request to the 5G core network upon receiving the first regeneration mode satellite access information of the first device to obtain the second regeneration mode satellite access information of the second device.

[0203] Optionally, in this embodiment, the second P-CSCF network element can determine whether both the first device and the second device support on-board communication service based on the first regeneration mode satellite access information and the second regeneration mode satellite access information. If it is determined that both the first device and the second device support on-board communication service, on-board communication service is provided for the first device and the second device.

[0204] In the above-mentioned method for determining on-board communication service, after the second P-CSCF network element of the second IMS network serving the second device receives the fourth SIP message sent by the second S-CSCF network element, it can obtain the first regeneration mode satellite access information of the first device from the fourth SIP message. In addition, since the second P-CSCF network element can also obtain the second regeneration mode satellite access information of the second device it serves, the second P-CSCF network element can determine whether to provide on-board communication service for the first device and the second device based on the obtained first and second regeneration mode satellite access information. This enables the IMS network to obtain the access information of both parties in the call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on the access information of both parties.

[0205] This embodiment will describe in detail the process by which the second P-CSCF network element determines whether to provide on-board communication service to the first and second devices based on the first regeneration mode satellite access information and the second regeneration mode satellite access information. In one embodiment, the above S902 includes:

[0206] Step D: If, based on the first regeneration mode satellite access information and the second regeneration mode satellite access information, it is determined that the first device and the second device meet the conditions for performing UE-satellite-UE service, then it is determined that on-board communication service will be provided to the first device and the second device.

[0207] The conditions for UE-satellite-UE service are to meet the conditions for on-board communication service between devices. Optionally, in this embodiment, the conditions for UE-satellite-UE service may include at least one of the following: the access type of both the first device and the second device is regenerative mode satellite access; the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable; and the locations of the first device and the second device meet the requirements for providing on-board communication service.

[0208] Optionally, in this embodiment, the second P-CSCF network element can determine whether the access types of both the first device and the second device are regenerative mode satellite access based on the first regenerative mode satellite access information and the second regenerative mode satellite access information; alternatively, it can determine whether the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable based on the first regenerative mode satellite access information and the second regenerative mode satellite access information; or it can determine whether the locations of the first device and the second device meet the requirements for providing on-board communication services based on the first regenerative mode satellite access information and the second regenerative mode satellite access information. Further, when the second P-CSCF network element determines that the first device and the second device meet at least one of the following conditions: both the access types of the first device and the second device are regenerative mode satellite access; the regenerative mode satellite identifier accessed by the first device and the regenerative mode satellite identifier accessed by the second device are connectable; or the locations of the first device and the second device meet the requirements for providing on-board communication services, it can be determined that on-board communication services can be provided to the first device and the second device.

[0209] In this embodiment, the process by which the second P-CSCF network element determines whether the first device and the second device meet the preset conditions based on the first regeneration mode satellite access information and the second regeneration mode satellite access information is relatively simple. This enables the second P-CSCF network element to quickly determine whether the first device and the second device meet the preset conditions based on the first regeneration mode satellite access information and the second regeneration mode satellite access information, thereby improving the efficiency of the second P-CSCF network element in determining whether to provide on-board communication services for the first device and the second device.

[0210] In some scenarios, the second P-CSCF network element can also send out the second regeneration mode satellite access information of the second device it serves, so that the first P-CSCF network element receiving the second regeneration mode satellite access information of the second device can determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information of the first device served by the first P-CSCF network element and the received second regeneration mode satellite access information of the second device. In one embodiment, the above method further includes:

[0211] Step E: If it is determined that the second device is in regenerative mode satellite access, send a fifth SIP message; the fifth SIP message includes the second regenerative mode satellite access information of the second device.

[0212] In this embodiment, when the second P-CSCF network element determines that the second device is using regenerative mode satellite access, it sends the second regenerative mode satellite access information of the second device in a fifth SIP message. Optionally, in this embodiment, the second P-CSCF network element can send the aforementioned fifth SIP message to the second S-CSCF network element, so that the second S-CSCF network element can send the aforementioned fifth SIP message to the first P-CSCF network element. Further, the first P-CSCF network element that receives the aforementioned fifth SIP message can determine whether to provide on-board communication service for the first device and the second device based on the aforementioned second regenerative mode satellite access information and the first regenerative mode satellite access information of the first device served by the first P-CSCF network element.

[0213] Optionally, in this embodiment, the second P-CSCF network element can carry the second regeneration mode satellite access information of the second device in the P-Access-Network-Info header field of the fifth SIP message and send it.

[0214] Alternatively, as an optional implementation, the second P-CSCF network element can send the second regeneration mode satellite access information of the second device to a trusted network element determined by the second P-CSCF network element. For example, if the second P-CSCF network element determines that the first P-CSCF network element is a trusted network element, then the second P-CSCF network element can directly send the aforementioned fifth SIP message to the first P-CSCF network element. The fifth SIP message triggers the first P-CSCF network element to determine whether to provide on-board communication service for the first device and the second device based on the first regeneration mode satellite access information of the first device it serves and the received second regeneration mode satellite access information.

[0215] Optionally, in this embodiment, the second P-CSCF network element can obtain the second regeneration mode satellite access information of the second device by subscription. Optionally, in this embodiment, the method by which the second P-CSCF network element subscribes to the second regeneration mode satellite access information of the second device includes, but is not limited to: notifying when the subscription event occurs and the subscription is valid.

[0216] In this embodiment, when the second P-CSCF network element determines that the second device is in regenerative mode satellite access, it sends a fifth SIP message. The fifth SIP message includes the second regenerative mode satellite access information of the second device. This allows the first P-CSCF network element, which receives the fifth SIP message, to determine whether to provide on-board communication service for the first device and the second device based on the second regenerative mode satellite access information and the first regenerative mode satellite access information of the first device served by the first P-CSCF network element. This enables the IMS network to obtain the access information of both parties in the call and determine whether to provide IMS voice service in UE-satellite-UE communication mode based on the access information of both parties.
