Description

Technical Field

[0001] The present invention relates to a system and method for improving a called connection rate, and in particular to a system and method for improving a called connection rate based on high-orbit and low-orbit satellite coordinated paging, and belongs to the field of satellite communications. Background Art

[0002] In recent years, natural disasters have occurred frequently, and people have paid more and more attention to satellite communications. Satellite communications have become an indispensable part. At the same time, people have higher and higher requirements for satellite communication technology capabilities.

[0003] Most of the existing satellite terminals are still attached to high-orbit satellites. Satellite terminal equipment under high-orbit satellites has high requirements for signal registration, and the communication capabilities of high-orbit satellites are relatively poor. During the period when ground users call satellite terminal equipment, due to geographical reasons (passing through tunnels), weather, obstacles and other factors, the satellite terminal equipment may not be able to communicate normally with ground equipment, affecting communication between people, especially in the event of natural disasters, which will have serious consequences.

[0004] However, the patent with patent number CN201811218447.0 only considers the process of ending the satellite voice call, disabling the satellite communication function, and controlling the satellite voice call function of the satellite communication device when the satellite communication device is in the satellite communication device state. It does not consider the processing of unfinished voice calls, resulting in low user communication smoothness and poor perceived effect. Summary of the invention

[0005] The object of the present invention is to provide a system and method for improving the call connection rate based on high-orbit and low-orbit satellite coordinated paging.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A system for improving the call connection rate based on high-orbit and low-orbit satellite coordinated paging, comprising:

[0007] Voice communication module, used for ground users to call satellite terminal equipment;

[0008] Low-orbit satellite communication module, based on satellite terminal equipment;

[0009] The core network GMSC is connected to the voice communication module and transmits corresponding signals;

[0010] A core network MSC receives a signal transmitted by the core network GMSC;

[0011] Core network SBC, used to send information;

[0012] A core network SLR receives a signal transmitted by the core network MSC;

[0013] The core network HLR is used to feed back signals and transmit signals to the core network MSC.

[0014] A working method of a system for improving a called connection rate based on high-orbit and low-orbit satellite coordinated paging, the working method comprising:

[0015] 1) When a ground user makes an incoming call to a satellite terminal, the telecommunications gateway sends a message through the core network SBC, and the core network GMSC receives the message and sends it to the core network MSC;

[0016] 2) The high-speed buffer SLR at the MSC analyzes the number to determine whether the service information of the number has been subscribed and whether the device has been connected to the network;

[0017] 3) If the satellite terminal device has been registered, VCM-HOS is automatically called to send a Paging Command message to the user. The user responds by sending a Paging RES message, and the gateway completes the authentication through the information sent by the HLR;

[0018] 4) The user sends a call establishment message to the core network MSC and the call connection is established.

[0019] Preferably, if the satellite terminal device prompts that it is not registered, the gateway station sends a prompt of call information failure to the core network MSC through the HLR, then automatically calls SM-LOS, sends a ringing instruction through the short data protocol, rings the satellite terminal device to remind it, keeps the voice channel occupied, and notifies the user in time. When the user receives the prompt tone of "device not registered", he / she promptly aligns the antenna direction to complete the device registration.

[0020] Preferably, after the device completes registration, the core network SLR receives a prompt that the device has been registered and switches to call VCM-HOS, the user sends a call establishment message to the core network MSC, the call connection is established, and the user completes the call in time.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By judging whether the satellite terminal equipment is registered in the network, a method for improving the call connection rate by using high-orbit and low-orbit satellite collaborative paging is proposed. The method adds a low-orbit satellite communication module to the terminal equipment, sends a ringing instruction through the short data protocol, and performs a ringing reminder operation on the unregistered satellite terminal equipment, so as to achieve the purpose of high-orbit and low-orbit collaborative paging, ensure timely calls between users, improve the call connection rate, improve the communication perception of satellite terminal equipment, reduce costs, reduce power consumption, improve user experience, and improve the overall service quality of satellite services.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1:

[0027] like Figure 1 to Figure 2 As shown: A system for improving the call connection rate based on high-orbit and low-orbit satellite coordinated paging, including

[0028] Voice communication module, used for ground users to call satellite terminal equipment;

[0029] Low-orbit satellite communication module, based on satellite terminal equipment;

[0030] The core network GMSC is connected to the voice communication module and transmits corresponding signals;

[0031] A core network MSC receives a signal transmitted by the core network GMSC;

[0032] Core network SBC, used to send information;

[0033] A core network SLR receives a signal transmitted by the core network MSC;

[0034] The core network HLR is used to feed back signals and transmit signals to the core network MSC.

[0035] A system and method for improving the called connection rate based on high- and low-orbit satellite collaborative paging is implemented based on satellite terminal equipment, VCM-HOS, SM-LOS, core network GMSC, core network MSC, core network SBC, core network SLR, and core network HLR. A low-orbit satellite communication module is added to the satellite terminal equipment, and the core network SLR determines whether the satellite terminal equipment is registered in the network. A ringing instruction is issued through a short data protocol to perform a ringing reminder operation on the unregistered satellite terminal equipment. In the case of high- and low-orbit satellite collaborative paging, the called connection rate is improved, which not only saves costs and reduces power consumption, but also ensures timely calls between users, improves the called connection rate, improves the communication perception of the satellite terminal equipment, improves the user experience, and improves the overall service quality of satellite services.

[0036] Embodiment 2

[0037] like Figure 2As shown: A working method of a system for improving a called connection rate based on high-orbit and low-orbit satellite coordinated paging, the working method comprising:

[0038] 1) When a ground user makes an incoming call to a satellite terminal, the telecommunications gateway sends a message through the core network SBC, and the core network GMSC receives the message and sends it to the core network MSC;

[0039] 2) The high-speed buffer SLR at the MSC analyzes the number to determine whether the service information of the number has been subscribed and whether the device has been connected to the network;

[0040] 3) If the satellite terminal device has been registered, VCM-HOS is automatically called to send a Paging Command message to the user. The user responds by sending a Paging RES message, and the gateway completes the authentication through the information sent by the HLR;

[0041] 4) The user sends a call establishment message to the core network MSC and the call connection is established.

[0042] Furthermore, if the satellite terminal device prompts that it is not registered, the gateway station sends a call information failure prompt to the core network MSC through the HLR, and then automatically calls SM-LOS, sends a ringing command through the short data protocol, and rings the satellite terminal device to remind it to keep the voice channel occupied and notify the user in time. When the user receives the "device not registered" prompt tone, he or she will align the antenna direction in time to complete the device registration.

[0043] Further, after the device completes registration, the core network SLR receives a prompt that the device has been registered and switches to call VCM-HOS. The user sends a call establishment message to the core network MSC, the call connection is established, and the user completes the call in time.

[0044] Embodiment 3

[0045] Taking the application of Tiantong-1 satellite in marine broadband scenarios as an example, Tiantong-1 satellite is a high-orbit satellite, and its satellite terminal equipment is integrated with a low-orbit satellite communication module. For users on the ocean, when they travel to an area not covered by the satellite beam, if they have not successfully registered for the network, SM-LOS is automatically called, and a ringing command is sent through the short data protocol to ring the satellite terminal equipment to remind the user to complete the device registration and network access in time.

[0046] By judging whether the satellite terminal equipment is registered with the network, and sending a ringing command through the short data protocol when it is not registered, the purpose of high and low orbit coordinated paging can be achieved, and the call connection rate can be improved to ensure the ability of users to talk. While saving costs, reducing delays and lowering power consumption, the smoothness of calls is improved, the user experience perception is enhanced, and the overall service quality of satellite services is improved.
