Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.
In the GEO satellite mobile communication system, wireless signal covers has following new characteristics:
Characteristics one: the GEO satellite covers lower, and the signal Cover Characteristics in dissimilar zones is different from ground network.The GEO satellite transit is the circuit orbit of plan range ground 36000km under the line.For terrestrial mobile terminal, the GEO satellite-signal of its reception can be subject to the impact that the ground area shading covers, and for the more area of ground veil, GEO satellite-signal shadow fading is more obvious, and the portable terminal received signal quality is relatively poor.In the land mobile communication system, the wireless signal in city covers best, thereby the timer duration of the periodic location update that adopts can be larger, upgrades the increase of the offered load that brings to reduce the position; In the rural area, outside of the city to wait region signal to cover not enough, and the normal timer duration that adopts less periodic location update loses tracking to portable terminal to avoid network, reduces the number of times of the ineffertive pager that network initiates.In the GEO satellite mobile communication system, compare opening, the impact that the GEO satellite signal quality that the urban area portable terminal receives can be covered owing to above ground structure is subjected to comparatively serious decline.Thereby, in the GEO satellite mobile communication system, it is less that the timer interval that the area that the veil such as city, mountain forest is more, mobile terminal period position are upgraded should arrange, and that the timer duration of the opening such as rural, open-air can arrange accordingly is larger.
Characteristics two: the large covering of GEO satellite.In the GEO satellite mobile communication network, adopt the technology of multi-beam antenna, wave beam is the minimum unit that the GEO satellite covers, and consists of a paging domain of GEO satellite mobile network.To between several thousand kms, its coverage is far longer than the scope that the single paging domain of land mobile communication network may cover to simple beam coverage radius at hundreds of.Compare and be the comparatively single area of signal Cover Characteristics in the latter's the single paging domain, in the GEO satellite mobile communication system, single wave beam covers lower polytype area that may include different signal Cover Characteristics, such as, cover simultaneously city, rural area, mountain forest, lake etc. under the simple beam.Therefore, in single paging domain, adopt the mode of single cycle position renewing timer time length in the land mobile communication system, in the GEO satellite mobile communication system, can't satisfy the demand that same wave beam covers the periodic location update of lower dissimilar regional portable terminals that is positioned at.
As shown in Figure 1, Fig. 1 is the GEO satellite mobile communication system Organization Chart of the embodiment of the invention.In an embodiment, the GEO satellite mobile communication system comprises portable terminal and satellite mobile communication network (perhaps being called satellite network).
