Embodiment 1

[0026] The precise synchronization of the satellite terminal in the DVB system is similar to the completion of the RRC connection establishment in the 5G NR system, and the satellite terminal enters the connected state at this time. If the DVB system and the 5G NR system are simply integrated, the satellite terminal will initiate the Registration Request process after the precise synchronization is achieved, such as image 3 3rd message shown (Ctrl PDU (to achieve fine synchronization)). Considering that in the satellite communication system, the time delay from the space base station to the ground core network is very large, this embodiment proposes a satellite terminal registration method based on DVB and 5G converged networking, including:

[0027] The random access process of the satellite terminal in the DVB access network and the registration process of the satellite terminal to the 5G core network are carried out in parallel, thereby reducing the registration delay of t...

Embodiment 2

[0033] This embodiment implements a satellite terminal based on DVB and 5G converged networking, and the satellite terminal is registered using the satellite terminal registration method described in Embodiment 1. Even the random access process of the satellite terminal in the DVB access network and the registration process of the satellite terminal to the 5G core network are performed in parallel, thereby reducing the registration delay of the satellite terminal.

[0034] As in Embodiment 1, the method for implementing the random access process of the satellite terminal in the DVB access network and the registration process of the satellite terminal to the 5G core network in parallel is as follows:

[0035] The Registration Request message in the registration process of the satellite terminal to the 5G core network is advanced to the random access process of the satellite terminal in the DVB access network. specifically:

[0036] The Logon PDU message sent by the satellite t...

Embodiment 3

[0039] This embodiment implements a DVB and 5G converged networking, where the DVB and 5G converged networking includes the satellite terminal described in Embodiment 2, as well as a base station and a 5G core network. Even if the satellite terminal is registered using the satellite terminal registration method described in Embodiment 1. Specifically, the random access process of the satellite terminal in the DVB access network and the registration process of the satellite terminal to the 5G core network are carried out in parallel, thereby reducing the registration delay of the satellite terminal.

[0040] As in Embodiment 1, the method for implementing the random access process of the satellite terminal in the DVB access network and the registration process of the satellite terminal to the 5G core network in parallel is as follows:

[0041]The Registration Request message in the registration process of the satellite terminal to the 5G core network is advanced to the random a...

Abstract

The invention provides a satellite terminal registration method, system and terminal based on DVB and 5G fusion networking, and the satellite terminal registration method comprises the steps: enabling a random access process of a satellite terminal in a DVB access network and a registration process of the satellite terminal to a 5G core network to be carried out in parallel, thereby reducing the registration time delay of the satellite terminal. According to the invention, the registration process does not need to be started when the random access process of the satellite terminal is completed, but the registration process is carried out at the same time when the random access process is started, so that the two processes are carried out in parallel, and the registration delay of the satellite terminal can be reduced.

Description

technical field [0001] The present invention relates to the field of information technology, in particular, to a satellite terminal registration method, system and terminal based on DVB and 5G fusion networking. Background technique [0002] The random access process in the DVB system is as follows figure 1 shown. The satellite terminal initiates the Logon PDU in the IDLE state, and enters the CONNECT state after sending the Ctrl PDU (to achieve fine synchronization). After the satellite terminal achieves fine synchronization, it can transmit service data. [0003] The random access process and registration process in the 5G NR system are as follows: figure 2 shown. The random access procedure is used for establishing a wireless link between the satellite terminal and the base station before performing the registration procedure, that is, the satellite terminal needs to establish an RRC connection with the base station before sending the Registration Request. The satell...
