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] This embodiment combines the specific conditions of the user and the satellite network to the technical solution of the present invention (the main process is as follows: figure 1 shown) for a detailed explanation.

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

[0035] (1) After receiving a new user access request, 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 the spare beam.

[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 ...

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 a new user within the coverage of the serving beam j initiates an access request. The user's priority is 1, and the user's location is The application resources are 120% of the remaining resources of the current beam. The center position of beam j is The coverage radius of the beam on the earth's surface is R e . Among them, the position coordinates are represented by latitude and longitude, that is, μ 1 , μ 2 is the longitude, is the latitude; assuming α=β=2, the profit coefficient m=1, and the cost coefficient n=2.

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

Embodiment 3

[0046] In this embodiment, it is assumed that the current satellite system includes 10 beams, all beams are in use, and the new user position is If the user is outside the coverage area 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 projection 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 a new user access request, first enter the first step, read the beams that are being served, and all beams are in service, then judge the user's location, 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 sequence. The distance is calcula...

Abstract

The invention discloses a broadband user access method in a satellite network, which is used for deciding a broadband access request of a user according to the geographic position of the user, the priority of the user, the resource demand of the user and the residual resource of a beam by comparing the income of accessing a new user and the cost of kicking out an original user. The serving beam is used as much as possible according to the user position, the spare beam resource is saved, the weighted base number of the user priority and the cost benefit coefficient of the user are introduced, and the user distinction degree between different priorities is improved; and, according to the invention, the access benefit maximization is ensured according to the profit cost comparison, a simple first arrival first acquisition mode is abandoned, and parameters can be changed according to the scheduling system and the requirements of the user, so that the decision of accessing and kicking out the user is 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 broadband resources required by broadband users directly determine which beams can provide services to users and in what form; on the other hand, the remaining resources of each beam also Determines whether the beam can serve it. Therefore, in the satellite communication network, it is necessary to make a broadband user's access decision, that is, to judge whether to provide services to users who have newly issued applications and in what way to provide services. [0003] At presen...
