Problems solved by technology

[0003] At present, in the existing methods, the access decision is usually only made directly according to the priority of the user, which leads to a low degree of discrimination, cannot guarantee the maximum access benefit, and also leads to a waste of satellite resources

Embodiment 1

[0033] In this embodiment, the technical solution of the present invention (the main process is as follows: figure 1 shown) are explained in detail.

[0034] In this embodiment, it is assumed that there are a total of 10 available beams in the current satellite system, all beams are in an idle state, and a priority is 1 and the application resource is 1 / 10 of the maximum resource of the beam at any position within the coverage of the satellite beam. of new users.

[0035] (1) After receiving an access request from a new user, the first step is to read the serving beams. In this embodiment, all beams are in an idle state, that is, there are no serving beams. So try to use spare beams.

[0036] (2) Judging whether the spare beam has enough time-frequency resources for the user to use, in this embodiment, the time-frequency resource required by the user is 1 / 10 of the maximum resource of the beam, and there are enough time-frequency resources for the user to use. The beam reso...

Embodiment 2

[0038] In this embodiment, it is assumed that the current satellite system includes 10 beams, and users in all beams are receiving services, and new users within the coverage of beam j being served initiate access requests. The user's priority is 1, and the user's location is The applied resources are 120% of the remaining resources of the current beam. The position of the center of beam j is The beam covers the Earth's surface with a radius R e . Among them, the position coordinates are expressed in latitude and longitude, that is, μ 1 , μ 2 is longitude, is the latitude; suppose α=β=2, the profit coefficient m=1, and the cost coefficient n=2.

[0039] (1) After receiving the access request of a new user, first enter the first step, read the beams that are in service, all beams are in service, then judge the user's location, first obtain the user's location, and each beam The position of the center point of the beam coverage, and the distance between the user posi...

Embodiment 3

[0046] In this embodiment, it is assumed that the current satellite system includes 10 beams, all beams are in use, and the position of the new user is Outside the coverage of the beam being used, the priority of the user is 7, and the application resource is 50% of the maximum time-frequency resource of the beam. The projected radius of the beam on the earth's surface is R e , α=β=2, profit coefficient m=1, cost coefficient n=2, there are 3 users under the beam with the lowest total cost among the 10 beams, and the user priorities are 2, 3, and 4 respectively.

[0047] (1) After receiving the access request of a new user, first enter the first step, read the beams that are in service, all beams are in service, then judge the user's location, and first obtain the user's location and the latitude and longitude of each beam coverage center point Calculate the distance between the user position and the center point of each beam in order, and use the haversine formula (Havers...

Abstract

The invention discloses a broadband user access method in a satellite network. According to the user's geographic location, user priority, user resource requirements and beam remaining resources, and by comparing the benefits of accessing new users and the cost of kicking out the original users, Decisions are made on user broadband access requests. The invention uses the serving beam as much as possible according to the user's location, saves the spare beam resources, and introduces the weighted base of the user's priority and the user's cost-benefit coefficient to improve the discrimination of users between different priorities; The cost comparison ensures that the benefit of access is maximized, and the simple first-come, first-served model is abandoned, and parameters can be changed according to the scheduling system and user needs, making the decision to access and kick out users more reasonable.

Description

technical field [0001] The invention relates to the technical field of broadband user access, in particular to a broadband user access method in a satellite network. Background technique [0002] The broadband satellite communication system is a kind of huge and complex network system. In the satellite communication network broadband service, the number of available beam resources will change continuously with the access of broadband users. On the one hand, the geographic location, priority, and required broadband resources of broadband users directly determine which beams can serve users and in what form; on the other hand, the remaining resources of each beam are also Determines whether the beam can serve it. Therefore, in a satellite communication network, it is necessary to make an access decision for broadband users, that is, to determine whether to provide services for users who have issued new applications and in what manner. [0003] At present, in the existing met...
