Embodiment 1

[0026] This embodiment provides a method for accessing a satellite communication link, which mainly includes the following operations:

[0027] Under the cellular system, the AT receives cell signals;

[0028] When the AT receives signals from multiple cells, and the multiple cells include cells whose bearer link type is satellite link bearer and wired link bearer, if the cell bearer link type is the signal of the cell carried by satellite link If the signals of these multiple cells are the strongest, the AT will access the cell carried by the satellite link after determining that the cell carried by the link type of the cell does not meet the set conditions.

[0029] Wherein, the setting conditions include that the signal of the cell is greater than or equal to the minimum noise ratio access threshold, and the cell load information is not overloaded.

[0030] Correspondingly, the signal of the cell carried by the satellite link is the strongest among the multiple cell signal...

Embodiment 2

[0047] This embodiment provides an access terminal AT, which mainly includes the following units.

[0048] a receiving unit for receiving cell signals;

[0049] The access unit is configured to determine that the cell bearer link type is satellite when the receiving unit receives signals from multiple cells, and the multiple cells include cells whose bearer link types are satellite link bearer and wired link bearer. The signal of the cell carried by the link is the strongest among the signals of multiple cells. Only when the cell carried by the link type of the cell is wired link does not meet the set conditions, it can access the cell carried by the satellite link;

[0050] Wherein, the setting conditions include that the signal of the cell is greater than or equal to the minimum noise ratio access threshold, and the cell load information is not overloaded.

[0051] Correspondingly, when the signal of the cell carried by the satellite link is the strongest among multiple cel...

Abstract

The invention discloses a satellite communication link access method and terminal and relates to the technical field of satellite communication and wireless cellular network mobile communication. The method comprises that an access terminal (AT) receives a cell signal under a cellular system; and when the AT receives signals of multiple cells, wherein the multiple cells comprises cells of bear link types of satellite link bearing and wired link bearing, if the signals of the cells of the satellite link bearing are strongest among the signals of the multiple cells, the AT determines that cells of wired link bearing do not meet preset conditions, and the AT accesses to the cells of satellite link bearing, wherein the preset conditions are that the signals of the cells are larger than or equal to the minimum noise ratio access threshold, and cell load information is non-overloaded. The invention also discloses an access terminal (AT). The technical scheme optimizes satellite link access bearing resource capacity maximization, and enables satellite link access bearing resources to be reasonably used.

Description

technical field [0001] The invention relates to the technical field of satellite communication and wireless cellular mobile communication, in particular to a satellite communication link access method and an access terminal. Background technique [0002] Currently, 2G\3G\4G and other cellular systems access the Internet in various bearer ways, among which the most widely used access bearer is through wired network access, but for some applications such as oceans and plateaus that are not conducive to the implementation of wired link bearer engineering Scenarios can generally be resolved using satellite links. Because satellite resources are very limited and the equipment is very expensive, when the satellite link is used for cellular system access bearer, its application resources are very precious, so its link capacity must be controlled to obtain a reasonable maximum application. [0003] When the physical coverage of the cable bearer access network node and the satellite...
