Problems solved by technology

[0004] Before the normal interaction of signaling in communication with the satellite system, in the prior art, the terminal is triggered to register and exchange information with the satellite router, that is, the prior art is based on user-level information registration, and its disadvantage is the capacity of the satellite system It is not enough to support the periodic registration of hundreds of millions of users in a short period of time, and the existing technology requires ground users to track the signals of the satellite network in real time, which poses a great challenge to the battery of ground user terminals

Embodiment 1

[0136] Embodiment 1: A layered network registration process consisting of a 2-layer network composed of a satellite network and a terrestrial network;

[0137] Such as figure 1 As shown, in a layered network of a 2-layer network composed of a layer of satellites and a ground network, a wireless network node (a wireless network node may be a base station in one embodiment, a base station controller in one embodiment, and in an implementation In this example, other control nodes may also periodically monitor and receive satellite network node signals. In two cases, a registration request is initiated:

[0138] (1) Cycle initiation request

[0139] (2) It is detected that the satellite node receiving the signal changes. For example, the wireless network node detects that the data received is that the new satellite node has changed or another beam of the original satellite node is serving it.

[0140] Specifically, when any of the above two situations is triggered, the wireles...

Embodiment 2

[0161] Embodiment two: if Image 6 As shown, the embodiment of the present invention provides a layered network registration method:

[0162] S110, the wireless network node initiates a registration request to a satellite node covering the wireless network node;

[0163] In one embodiment, the wireless network node may be a base station, in one embodiment it may be a base station controller, in one embodiment it may also be other control nodes.

[0164] S120 After receiving the registration request, the satellite node will send its own attribute information and beam information as the result of the registration request (that is, the registration result) to the wireless network node in the registration response message, and the wireless network node obtains the registration of the satellite node As a result, the registration result includes attribute information and beam information of the satellite node;

[0165] In one embodiment, the satellite node's own attribute informat...

Embodiment 3

[0177] Embodiment three: as Figure 7 As shown, the embodiment of the present invention provides a method for establishing a data session, which involves a single user handover from the ground to the satellite network, which can enhance the performance of signal supplementation and handover by the user using the satellite link.

[0178] It can be known from the above embodiments that the wireless network node broadcasts the obtained registration result to the covered mobile users. After a mobile user receives a broadcast message from a wireless network node (base station, base station controller, and other control nodes), it updates the attribute information and beam information of the satellite node serving it. This information can be used for users to quickly switch from the ground to the satellite network.

[0179] After the terminal finishes updating the current satellite network signal information, when the ground signal is too poor (for example, there is no signal for a...

Abstract

An embodiment of the invention discloses a registration method for a hierarchical network. The method is applied to the hierarchical network composed of a ground network and at least one layer of air network. The method is characterized by comprising steps that a wireless network node acquires a registration result of an air network node, wherein the wireless network node is disposed in the ground network while the air network node is disposed in the air network and covers the wireless network node, and the registration result includes the attribute information and wave beam information of the air network node; the wireless network node broadcasting the registration result to mobile users covered by the wireless network node. The air network in the invention can be a satellite network and the hierarchical network is composed of the satellite network and the ground wireless network. The air network in the invention can be a balloon network and the hierarchical network is composed of the balloon network and the ground wireless network.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a layered network registration method, device and system. Background technique [0002] After years of development, satellite communication technology is widely used in remote sensing, monitoring, logistics tracking, positioning, broadcasting and broadband services. The status quo of satellite communications is an independent development, operated separately. In 1987, the global penetration rate of mobile phones was less than 10%, the technology was immature, and the calling area was limited, and the roaming and switching between GSM networks often resulted in dropped calls. The "Iridium Project" enables human beings to communicate in any "place where they can see the sky" that can be interrupted, creating a "true global communication". The subsequent result was that due to the rapid development of technology, GSM users and services were developed smoothly, while the sate...
