Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a service transmission method, apparatus, communication equipment, storage medium, and program product. Background Art

[0002] In the Release 19 phase of 3GPP SA2, a satellite regeneration model will be implemented. This model transfers base stations and / or some core network functions to satellites for service transmission between base stations and terminals. This model is widely used in various service transmission scenarios due to its advantages, such as reduced dependence on terrestrial networks, flexible networking, and reduced communication latency.

[0003] In traditional technology, when uplink and downlink SMS services are transmitted according to the satellite regeneration mode, the on-board network element Mobility Management Entity (MME) in the satellite regeneration mode can perform store-and-forward operations on uplink SMS messages to forward the uplink SMS messages to the ground SMS network element, or perform store-and-forward operations on downlink SMS messages to forward the downlink SMS messages to the terminal, thereby completing the efficient transmission of uplink and downlink SMS services.

[0108] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0109] Figure 1 Schematic diagram of an application scenario of a service transmission method provided in an embodiment of the present application. Figure 1 As shown in the figure, this scenario includes a Mobility Management Entity (MME) 100, a Gateway MSC for Short Message Service (SMS-GMSC) 200, a User Equipment (UE) 300, a Service Centre (SC) 400, and a Home Subscriber Server (HSS) 500. Data is transmitted over the network between the MME 100 and the SMS-GMSC 200, UE 300, and HSS 500; data is transmitted over the network between the SMS-GMSC 200 and SC 400; and data is transmitted over the network between the HSS 500 and the SMS-GMSC 200 and SC 400.

[0110] UE 300 may be a wireless terminal, which may be a device that provides voice and / or other service data connectivity to a user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem. A wireless terminal may communicate with one or more core networks via a Radio Access Network (RAN). A wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal. For example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device may exchange voice and / or data with a radio access network. A wireless terminal may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, user agent, user device, or user equipment, without limitation herein.

[0111] MME is a satellite network element. When MME is connected to a ground station, data can be exchanged with ground network elements through the ground station, where the ground network elements may include HSS, SMS-GMSC, etc. In traditional technology, SC sends a downlink SMS to SMS-GMSC. After MME receives the downlink SMS sent by SMS-GMSC, it stores the downlink SMS in MME. After MME establishes a connection with UE, MME sends the downlink SMS to UE and receives the delivery report returned by UE. If MME fails to send the delivery report to SMS-GMSC within the preset time, the downlink SMS fails to be sent, and SC resends the downlink SMS to SMS-GMSC. However, if the preset time does not change, the retransmission of the downlink SMS will still fail. Based on this, there is a problem of low success rate when transmitting downlink SMS services through MME in traditional technology.

[0112] Based on the above conventional technology, the embodiments of the present application provide a service transmission method, which transmits service information to the UE by determining whether the SMS-GMSC can successfully receive the delivery report, thereby improving the success rate of downlink SMS service transmission through the MME.

[0113] 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.

[0114] 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.

[0115] In one embodiment, Figure 2 As shown, a business transmission method is provided, which is applied to Figure 1 The following steps are used as an example to illustrate the MME in FIG.

[0116] S201, receiving a first service request sent by a short message service gateway SMS-GMSC; the first service request includes service information and time information.

[0117] The service information may be a downlink SMS message, and the time information may include information such as the sending time of the first service request.

[0118] In an embodiment of the present application, a service center (SC) sends service information to a short message service gateway (SMS-GMSC). The SMS-GMSC generates a first service request based on the service information and time information. The mobility management entity (MME) is a satellite network element, and the SMS-GMSC is a ground network element. When a satellite establishes a connection with a ground station, the satellite network element can communicate with the ground network element. Therefore, when the satellite establishes a connection with the ground station, the SMS-GMSC sends the first service request to the MME, so that the MME performs service transmission according to the first service request.

[0119] S202: Determine whether the SMS-GMSC can successfully receive the delivery report based on the time information, and obtain a determination result.

[0120] The determination result includes whether the SMS-GMSC can successfully receive the delivery report or whether the SMS-GMSC fails to successfully receive the delivery report.

[0121] In an embodiment of the present application, the time at which the SMS-GMSC receives the delivery report is predicted based on the time information to obtain a determination result. Optionally, the MME may pre-store the corresponding reception duration for each terminal, where the time information may include a preset duration. The MME may determine the corresponding user equipment (UE) based on the first service request and further determine the corresponding reception duration for the UE. When the reception duration is less than or equal to the preset duration, the determination result is that the SMS-GMSC successfully received the delivery report; when the reception duration is greater than the preset duration, the determination result is that the SMS-GMSC failed to successfully receive the delivery report.

[0122] S203: Transmit service information to the user terminal UE according to the determination result.

[0123] In an embodiment of the present application, when the determination result is that the SMS-GMSC can successfully receive the delivery report, the MME transmits the service information to the UE; when the determination result is that the SMS-GMSC fails to successfully receive the delivery report, the MME feeds back a message of failure to the service center (SC), triggering the retransmission of the service information. Further, when the SMS-GMSC can successfully receive the delivery report corresponding to the retransmitted service information, the MME transmits the service information to the UE.

[0124] In the above-mentioned service transmission method, a first service request sent by a short message service gateway (SMS-GMSC) is received; the first service request includes service information and time information; a determination is made based on the time information as to whether the SMS-GMSC can successfully receive a delivery report, obtaining a determination result; and the service information is transmitted to a user terminal (UE) based on the determination result. Transmitting the service information to the UE based on the determination result improves the success rate of service information transmission via the MME. Furthermore, upon receiving the first service request, a determination is made based on the time information in the first service request as to whether the SMS-GMSC can successfully receive the delivery report, thereby avoiding wasting network resources by sending service information to the UE if the SMS-GMSC cannot successfully receive the delivery report.

[0125] In one embodiment, Figure 3 As shown, “determining whether the SMS-GMSC can successfully receive the delivery report according to the time information and obtaining a determination result” includes:

[0126] S301 : Predicting the time when the SMS-GMSC receives the delivery report based on the ephemeris information of the MME, the location information of the UE, and the location information of the ground station corresponding to the SMS-GMSC to obtain a predicted reception time.

[0127] It should be noted that SMS-GMSC can correspond to one or more ground stations. For example, when SMS-GMSC corresponds only to ground station 1, when MME establishes a connection with ground station 1, SMS-GMSC sends the first service request to MME through ground station 1. After MME receives the delivery report, when MME establishes a connection with ground station 1 again, MME sends the delivery report to SMS-GMSC through ground station 1; when SMS-GMSC corresponds to ground station 1, ground station 2, and ground station 3, when MME establishes a connection with any one of ground stations 1, ground station 2, and ground station 3, SMS-GMSC sends the first service request to MME through the ground station established with MME. After MME receives the delivery report, when MME establishes a connection with any one of ground stations 1, ground station 2, and ground station 3 again, MME sends the delivery report to SMS-GMSC through the ground station.

[0128] In an embodiment of the present application, the MME pre-stores the MME's ephemeris information, the location information of each terminal served, and the location information of the ground station corresponding to the SMS-GMSC. The MME determines the terminal corresponding to the first service request based on the first service request, and further determines the location information of the terminal. Thus, based on the MME's ephemeris information, the UE's location information, and the location information of the ground station corresponding to the SMS-GMSC, the MME determines the time difference between the current moment and the moment when the MME receives the delivery report, as well as the duration for the MME to receive the delivery report and send it to the SMS-GMSC, and then determines the predicted reception time based on the above time difference and duration.

[0129] S302: Determine whether the SMS-GMSC can successfully receive the delivery report based on the predicted receiving time and the time information, and obtain a determination result.

[0130] Optionally, the time information may be a preset receiving time. When the predicted receiving time is less than or equal to the preset receiving time, the determination result may be that the SMS-GMSC can successfully receive the delivery report; when the predicted receiving time is greater than the preset receiving time, the determination result may be that the SMS-GMSC fails to successfully receive the delivery report.

[0131] In this embodiment, the MME predicts the time when the SMS-GMSC receives the delivery report based on the MME's ephemeris information, the UE's location information, and the location information of the ground station corresponding to the SMS-GMSC, using known data. This improves the accuracy of the determination result. The method of using ephemeris information and location information for prediction is relatively simple and does not require the use of a large amount of computing resources.

[0132] In one embodiment, Figure 4As shown, “predicting the time when the SMS-GMSC receives the delivery report based on the MME's ephemeris information, the UE's location information, and the location information of the ground station corresponding to the SMS-GMSC to obtain the predicted reception time” includes:

[0133] S401: Determine, based on the MME's ephemeris information and the UE's location information, a first time for the MME to connect to the UE for information transmission.

[0134] The MME's ephemeris information is a table of the precise position or trajectory of the satellite as it changes over time and is a function of time.

[0135] In an embodiment of the present application, when the satellite moves to the preset range corresponding to the UE, the MME can establish a connection with the UE. Based on the MME's ephemeris information, the time, coordinates, orientation, speed and other parameters corresponding to the satellite can be determined. Thus, based on the coordinates corresponding to the satellite and the position information of the UE, the flight distance between the satellite and the position where it can connect with the UE can be determined. Furthermore, based on the flight distance and the speed corresponding to the satellite, the first time when the MME connects to the UE for information transmission is obtained.

[0136] S402: Determine a second time for the MME to connect to the SMS-GMSC for information transmission based on the MME's ephemeris information and the location information of the ground station corresponding to the SMS-GMSC.

[0137] In an embodiment of the present application, when the satellite moves to a preset range corresponding to the ground station, the MME can establish a connection with the ground station, thereby communicating with the SMS-GMSC based on the ground station. Based on the MME's ephemeris information, the time, coordinates, orientation, speed and other parameters corresponding to the satellite can be determined, thereby determining the flight distance between the satellite and the position where it can be connected to the ground station based on the coordinates corresponding to the satellite and the position information of the ground station. Furthermore, based on the flight distance and the speed corresponding to the satellite, the second time for the MME to connect to the SMS-GMSC for information transmission is obtained.

[0138] S403: Predict the time when the SMS-GMSC receives the delivery report based on the first time and the second time to obtain a predicted reception time.

[0139] In an embodiment of the present application, the time when the SMS-GMSC receives the delivery report can be predicted based on the first time, the second time, and the time when the MME receives the first service request. For example, the time when the MME receives the first service request and the sum of the first time and the second time are used as the predicted reception time.

[0140] In this embodiment, the first time is determined based on the MME's ephemeris information and the UE's location information, and the second time is determined based on the MME's ephemeris information and the location information of the ground station corresponding to the SMS-GMSC, thereby predicting the time when the SMS-GMSC receives the delivery report, making the predicted reception time more accurate.

[0141] In one embodiment, Figure 5 As shown, the time information includes the sending time and the timing duration, and "determining whether the SMS-GMSC can successfully receive the delivery report based on the predicted receiving time and the time information, and obtaining a determination result" includes:

[0142] S501, determining the time difference between the predicted receiving time and the sending time.

[0143] Among them, the sending time is the time when SMS-GMSC sends the first service request to MME; the timing duration is a preset duration. The service information is stored in SMS-GMSC during the timing duration. After the timing duration expires, SMS-GMSC deletes the service information from the local. That is, after the timing duration expires, the delivery report returned by the UE received by SMS-GMSC indicates that the service information transmission failed.

[0144] In an embodiment of the present application, a difference operation is performed on the predicted receiving time and the sending time to obtain the time difference.

[0145] S502: If the time difference is greater than the timing duration, it is determined that the SMS-GMSC fails to successfully receive the delivery report.

[0146] In the embodiment of the present application, when the time difference is greater than the timing duration, it indicates that the MME has timed out when sending the delivery report to the SMS-GMSC, and the SMS-GMSC has deleted the service information, then it is determined that the SMS-GMSC has failed to successfully receive the delivery report.

[0147] S503: If the time difference is not greater than the timing duration, it is determined that the SMS-GMSC can successfully receive the delivery report.

[0148] In the embodiment of the present application, when the time difference is less than or equal to the timing duration, it indicates that the SMS-GMSC can receive the delivery report within the timing duration, that is, the service information is successfully transmitted.

[0149] In summary, this embodiment determines whether the SMS-GMSC can successfully receive the delivery report by comparing the time difference and the timing duration. The judgment method is simple, accurate, and error-prone, thus avoiding multiple service information transmission failures due to inaccurate determination results.

[0150] In one embodiment, "transmitting service information to the user terminal UE according to the determination result" includes: when the determination result is that the SMS-GMSC fails to successfully receive the delivery report, sending a response message to the SMS-GMSC; the response message includes a time difference; the time difference represents the time difference between the predicted time when the SMS-GMSC receives the delivery report and the time when the SMS-GMSC actually sends the first service request.

[0151] In an embodiment of the present application, when it is determined that the SMS-GMSC failed to successfully receive the delivery report, the MME feeds back a response message to the SMS-GMSC, where the response message carries the time difference between the predicted reception time and the transmission time, so that the SMS-GMSC can modify the timing duration according to the time difference. When the SMS-GMSC resends the service information to the MME, a new service request is generated based on the service information and the modified timing duration, and the MME does not transmit the service information to the UE before receiving the resent service information, thereby reducing service transmission resources.

[0152] In this embodiment, when the determination result is that the SMS-GMSC fails to successfully receive the delivery report, the MME feeds back a response message to the SMS-GMSC, so that the SMS-GMSC obtains the message that the current service information transmission fails.

[0153] In one embodiment, “transmitting service information to the user terminal UE according to the determination result” includes:

[0154] S601: If the result of determination is that the SMS-GMSC can successfully receive the delivery report, the service information is sent to the UE, and the delivery report returned by the UE based on the service information is sent to the SMS-GMSC.

[0155] In an embodiment of the present application, when it is determined that the SMS-GMSC can successfully receive the delivery report, the SMS-GMSC can receive the delivery report within the scheduled time period. Therefore, the MME continues the service transmission process, and when the MME establishes a connection with the UE, the service information is sent to the UE. Further, the delivery report returned by the UE based on the service information is received, and when the MME establishes a connection with the ground station, the delivery report is sent to the SMS-GMSC through the ground station.

[0156] In this embodiment, when the result of determination is that the SMS-GMSC can successfully receive the delivery report, service transmission is performed normally and service information is sent to the UE, so that the SMS-GMSC can receive the delivery report returned by the UE in a timely manner.

[0157] In one embodiment, Figure 6 As shown, the above service transmission method may further include:

[0158] S204, receiving a second service request sent by the SMS-GMSC; the second service request includes service information and new time information; the new time information is determined by the SMS-GMSC according to the response message sent by the MME last time.

[0159] In an embodiment of the present application, the SC resends the service information to the SMS-GMSC, and the SMS-GMSC forms a second service request based on the service information and the new time information carried in the response message sent by the MME last time. When the ground station establishes a connection with the satellite again, the SMS-GMSC sends the second service request to the MME through the ground station, so that the MME performs service transmission according to the second service request.

[0160] In this embodiment, the SMS-GMSC forms a second service request based on the service information and the new time information. The MME receives the second service request sent by the SMS-GMSC and transmits the service based on the new time information, thereby preventing the SMS-GMSC from failing to receive the delivery report returned by the UE within the scheduled duration.

[0161] In one embodiment, Figure 7 As shown, the above service transmission method may further include:

[0162] S602: Store the business information in a local preset storage location.

[0163] In an embodiment of the present application, after receiving the first service request or the second service request, the MME parses the first service request or the second service request to obtain service information. A service information database can be pre-set in the MME, and the service information database is used as a preset storage location for the service information. When it is determined that the SMS-GMSC can successfully receive the delivery report, the service information is stored in the local preset storage location.

[0164] Optionally, the determination result may be a determination result obtained by the MME according to the first service request; or, the determination result may also be a determination result obtained by the MME according to the second service request.

[0165] S603: Establish a connection with the UE.

[0166] In an embodiment of the present application, when the satellite flies to a preset range corresponding to the terminal, the satellite network element MME establishes a connection with the UE, and the MME can perform data transmission with the UE through the communication connection.

[0167] S604: After establishing a connection with the UE, the service information is sent to the UE.

[0168] In an embodiment of the present application, after the MME establishes a connection with the UE, the service information is sent to the UE. Further, the delivery report returned by the UE based on the service information is received, and when the MME establishes a connection with the ground station, the delivery report is sent to the SMS-GMSC through the ground station.

[0169] In this embodiment, when the determination result is that the SMS-GMSC can successfully receive the delivery report, the MME stores and transmits the service information to ensure the timeliness of service transmission.

[0170] In one embodiment, Figure 8 As shown, the above service transmission method may further include:

[0171] S605: Receive a reception response message sent by the UE based on the service information.

[0172] In an embodiment of the present application, the MME sends the service information to the UE, and the UE feeds back a reception response message to the MME based on the service information, so that the MME obtains information that the service information has been successfully sent.

[0173] S606: Receive and store uplink information sent by the UE based on the service information; the uplink information includes a delivery report.

[0174] The uplink information includes a delivery report, and may also include an uplink short message.

[0175] In an embodiment of the present application, the UE sends a delivery report and an uplink short message to the MME based on the service information. The MME stores the delivery report and the uplink short message in a local preset storage location so as to send the uplink information to the SMS-GMSC when establishing a connection with the ground station.

[0176] S607: The uplink information also includes an uplink short message, and the uplink short message returned by the UE is sent to the SMS-GMSC.

[0177] In the embodiment of the present application, when the MME establishes a connection with the ground station, the uplink short message returned by the UE is sent to the SMS-GMSC through the ground station.

[0178] In this embodiment, after sending the service information to the UE, the MME receives uplink information returned by the UE and sends the uplink information to the SMS-GMSC, thereby completing the transmission of the service information.

[0179] In one embodiment, Figure 9 As shown, a business transmission method is provided, which is applied to Figure 1 The SMS-GMSC in the example is used to illustrate the process, which includes the following steps:

[0180] S701, receiving business information sent by the service center SC.

[0181] In the embodiment of the present application, the SC and the SMS-GMSC are both terrestrial network elements. The SC can establish a communication connection with the SMS-GMSC. Furthermore, the SC sends service information to the SMS-GMSC, and the service information can be a downlink text message.

[0182] S702, sending a first service request to the MME; the first service request includes service information and time information; the first service request is used to instruct the MME to determine whether the SMS-GMSC can successfully receive the delivery report based on the time information, obtain a determination result, and transmit the service information to the UE based on the determination result.

[0183] In an embodiment of the present application, the SMS-GMSC generates a first service request based on service information and time information. When a connection is established between the satellite and the ground station, the SMS-GMSC sends the first service request to the MME via the ground station, so that the MME can predict the time when the SMS-GMSC receives the delivery report based on the time information, and obtain a determination result. When the determination result is that the SMS-GMSC can successfully receive the delivery report, the MME transmits the service information to the UE. When the determination result is that the SMS-GMSC cannot successfully receive the delivery report, the MME feeds back a message indicating the failure to send the service information to the SC, triggering the retransmission of the service information. Further, when the SMS-GMSC can successfully receive the delivery report corresponding to the retransmitted service information, the MME transmits the service information to the UE.

[0184] In the above-mentioned service transmission method, service information sent by a service center (SC) is received; a first service request is sent to an MME; the first service request includes service information and time information; the first service request is used to instruct the MME to determine, based on the time information, whether the SMS-GMSC can successfully receive a delivery report, obtain a determination result, and transmit the service information to the UE based on the determination result. Transmitting the service information to the UE based on the determination result improves the success rate of service information transmission through the MME. Simultaneously, upon receiving the first service request, determining, based on the time information in the first service request, whether the SMS-GMSC can successfully receive the delivery report avoids wasting network resources by sending service information to the UE if the SMS-GMSC cannot successfully receive the delivery report.

[0185] In one embodiment, Figure 10 As shown, the above service transmission method may further include:

[0186] S703, receiving a response message sent by the MME; the response message includes the time difference between the time when the MME predicts that the SMS-GMSC receives the delivery report and the time when the SMS-GMSC actually sends the first service request; the response message is sent by the MME when it determines that the SMS-GMSC fails to successfully receive the delivery report.

[0187] In an embodiment of the present application, the MME predicts the time when the SMS-GMSC receives the delivery report based on the MME's ephemeris information, the UE's location information, and the location information of the ground station corresponding to the SMS-GMSC to obtain a predicted reception time. The MME obtains the time information by parsing the first service request, and determines whether the SMS-GMSC can successfully receive the delivery report based on the sending time and timing duration in the time information, as well as the predicted reception time. If the SMS-GMSC cannot successfully receive the delivery report, the time difference between the time when the SMS-GMSC receives the delivery report and the time when the SMS-GMSC actually sends the first service request is carried in a response message and sent to the SMS-GMSC.

[0188] In this embodiment, when the SMS-GMSC fails to successfully receive the delivery report, the SMS-GMSC receives the response message sent by the MME, thereby obtaining the message of service information sending failure in a timely manner.

[0189] In one embodiment, Figure 11 As shown, the above service transmission method may further include:

[0190] S704: Send a path acquisition request to the home subscriber server HSS.

[0191] In the embodiment of the present application, in order to establish a connection with the MME, the SMS-GMSC sends a path acquisition request to the Home Subscriber Server (HSS) to obtain the routing information of the MME.

[0192] S705: Receive routing information sent by the HSS based on the path acquisition request.

[0193] In this embodiment of the present application, the HSS responds to the path acquisition request, determines the routing information corresponding to the MME from a preset path library, and sends the routing information to the SMS-GMSC. Optionally, the routing information can be the address information of the MME, or the data transmission path when the SMS-GMSC communicates with the MME.

[0194] S706: Send a first service request to the MME according to the address indicated by the routing information.

[0195] In the embodiment of the present application, when the satellite establishes a connection with the ground station, the SMS-GMSC sends a first service request to the MME according to the routing information.

[0196] In this embodiment, the SMS-GMSC interacts with the HSS to accurately obtain the routing information of the MME, thereby ensuring the accuracy of service transmission.

[0197] In one embodiment, Figure 12 As shown, the above service transmission method may further include:

[0198] S707, sending a delivery report status message to the HSS and a delivery failure message to the SC; the delivery report status message is used to instruct the HSS to send a request to resend the service information to the SC when receiving the connection success message sent by the MME.

[0199] In an embodiment of the present application, when the MME determines that the SMS-GMSC cannot successfully receive the delivery report returned by the UE and the SMS-GMSC receives a response message sent by the MME, the SMS-GMSC sends a failure message to the SC and sends a delivery report status message to the HSS, so that the HSS adds the indication information that the service message was not successfully sent to the queue. Furthermore, when the HSS receives the connection success message sent by the MME, it sends a request to the SC to resend the service information.

[0200] In this embodiment, when the SMS-GMSC receives the response message sent by the MME, it sends a delivery report status message to the HSS and sends a delivery failure message to the SC, so that the service message can be resent normally.

[0201] In one embodiment, Figure 13 As shown, the above service transmission method may further include:

[0202] S708, receiving the service information sent by the SC.

[0203] In the embodiment of the present application, after receiving the request for resending the service information sent by the HSS, the SC resends the service information to the SMS-GMSC.

[0204] S709, sending a second service request to the MME; the second service request includes service information and new time information; the new time information is determined by the SMS-GMSC based on the response message received from the MME.

[0205] In an embodiment of the present application, when the MME determines that the SMS-GMSC cannot successfully receive the delivery report returned by the UE, the MME sends a response message to the SMS-GMSC, which includes the time difference between the time when the SMS-GMSC receives the delivery report and the time when the SMS-GMSC actually sends the first service request. The SMS-GMSC determines new time information based on the time difference, and the SMS-GMSC generates a second service request based on the service information and the new time information, and sends the second service request to the MME.

[0206] In this embodiment, the SMS-GMSC generates a second service request according to the service information and the new time information, and resends the service information, so that the service information can be successfully sent by applying the new time information.

[0207] In one embodiment, Figure 14 As shown, the above service transmission method may further include:

[0208] S710, receiving a delivery report sent by the MME, and sending the delivery report to the SC; the delivery report is returned by the UE based on the service information.

[0209] In an embodiment of the present application, the UE sends a delivery report to the MME based on the service information, and the MME stores the delivery report in a local preset storage location, so as to send the delivery report to the SMS-GMSC when establishing a connection with the ground station, and the SMS-GMSC forwards the delivery report to the SC.

[0210] In this embodiment, the SMS-GMSC receives the delivery report indicating that the service information is successfully transmitted. The SMS-GMSC forwards the received delivery report to the SC to complete the transmission of the service information.

[0219] S8. The MME determines the time difference between the predicted reception time and the transmission time.

[0220] S9, if the time difference is greater than the timing duration, the MME determines that the SMS-GMSC fails to successfully receive the delivery report; if the time difference is not greater than the timing duration, the MME determines that the SMS-GMSC can successfully receive the delivery report.

[0221] S10, if the result of determination is that the SMS-GMSC fails to successfully receive the delivery report, then execute steps S11-S14; if the result of determination is that the SMS-GMSC can successfully receive the delivery report, then skip steps S11-S14.
