Description

The method and system of Incorporate network medium and low earth orbit satellites communication

Technical field

The present invention relates to communication technical field, more particularly to Incorporate network medium and low earth orbit satellites communication method and System.

Background technology

The concept of MM (Mobile Management, mobile management), is suggested in a cellular communication network earliest and makes With.In mobile radio network, network needs to be tracked mobile user terminal, and provides service for which, so that mobile User terminal between being capable of proper communication, it is ensured that user terminal is maintained in motion process and other users terminal or fixed knot Communication between point.In order to ensure that optional position of the user terminal in whole network coverage can stably from network Middle to obtain service, the effect of MM becomes especially prominent.

So-called MM is carried between the mark (node name) of mobile node and its address (position of node Relative Network structure) For time-varying mapping, be a kind of supports that roamer reaches the basic fundamental that new service area goes to receive to service.These nets Network includes：Internet (interconnection network, internet), satellite network, Ad hoc networks (Ad hoc nets Network is a kind of multi-hop, acentric, ad hoc deployed wireless networks, is also called multihop network) or its mixing any form network. The major function of MM is that the seamless roam of user, equipment and service is effectively supported in whole service network.MM has two mainly Research in terms of：Location management and handover management.In general, location management process user database inquiry and storage with And the transmission of paging signal, handover management keeps connective by controlling the change of access point in movement.

The addressing problem of LEO (Low Earth Orbit, Low Earth Orbit) satellite network is different from the fixed net of land Network and mobile network, LEO satellite are in high-speed moving state relative to ground, cause inter-satellite link and satellite-ground link to need into line frequency Numerous switching.The inter-satellite link of satellite network can be divided into two kinds：Inter-satellite link and different rails in same orbital plane between satellite Inter-satellite link between the satellite of road face.Between the satellite of different orbital planes, by satellite motion direction, antenna point to and antenna with There is periodically switch (i.e. link break-make) and ask in the restriction of the factors such as track ability, the inter-satellite link between different orbital plane satellites Topic.As the inter-satellite link that there is a plurality of different orbital planes in Constellation of Low Earth Orbit Satellites, therefore the network caused by above-mentioned reason are opened up The change for flutterring structure is very frequent, and the topological structure of whole network has high dynamic variation characteristic.In addition, as LEO is defended Elevation relatively low (700-1500km), the area coverage over the ground of single satellite is little (to account for 3%-the 5% of global surface product, minimum 10 ° of the elevation angle), Constellation of Low Earth Orbit Satellites covering the whole world needs to be made up of plurality of satellite, up to tens of Dao hundreds of.It is right For the Constellation of Low Earth Orbit Satellites of Global coverage, the relative position between LEO satellite was continually changing with the time, was existed substantial amounts of Overlapping coverage areas, LEO satellite user can see many LEO satellites simultaneously in majority.

In the network towards Incorporate, when certain LEO satellite provides service for certain user terminal, as LEO is defended Star is in real time kinematics state, and the LEO satellite may and no longer be that the optimal access satellite of the user terminal (or have left Access scope), then the user terminal needs to be switched to other LEO satellites and is accessed.Due to the topology of spatial network itself Change and the quick renewal of terrestrial user information, the routing table that LEO satellite needs are maintained will be very huge, and the routing table By with the change in topology frequent updating of spatial network and ground network, this causes the addressing scheme of LEO satellite to be faced with front institute Not some challenges.

LEO satellite network Satellite number is more, the orbital period is short, network topology change is fast and overlay area is little (compares For high rail satellite), the data transmission procedure that this feature results in LEO satellite is different from ground network.In existing LEO satellite In network, extensively using mobile IP technology, the mobile of a large number of users terminal can cause substantial amounts of location updating message and position The time delay that fresh information transmission brings.And in satellite communication system, as satellite is constantly in high-speed motion state, its clothes The business area of coverage is also constantly in change, even if therefore user terminal remain static relative to ground, similarly frequently face Face the switching with satellite.

In existing mobile IP technology, (Paging Extensions for Mobile IP, mobile IP seek such as P-MIP Exhale extension) agreement and Cellular IP (cellular ip) agreement, corresponding expansion has been carried out on the basis of basic mobile IP protocol Exhibition, increased IP paging functions, but while also all there is certain, such as P-MIP agreements, not support the paging for localizing Strategy, with the motion of LEO satellite, user understands that distance registration satellite is more and more remote, produces longer forwarding chain, can cause to prolong When while produce excessive signalling loads, cause the waste of telecommunication system resources.And Cellular IP are not provided with paging Area, no matter this causes satellite area size send paging come new information using timing, can consume big in satellite network The energy of the wireless network resource and user terminal of amount, causes the waste of telecommunication system resources.

In a word, in Incorporate network, using existing mobile IP technology, the wave of telecommunication system resources can be caused Take.

First, in the method that the Incorporate network medium and low earth orbit satellites of the embodiment of the present invention communicate, ground to be divided Subregion and user terminal and satellite are addressed：

Earth surface is divided into by the first step according to the quantity of the communication range and satellite of MEO/LEO Satellite Constellation Satellite Multiple ground subregions, and allocation identification is distinguished for multiple ground distributor areas, wherein, each the ground subregion in all ground subregions Mark is fixed and unique, and MEO/LEO Satellite Constellation is the satellite constellation in Incorporate network.

In the embodiment of the present invention by taking the MEO/LEO Satellite Constellation being made up of 48 satellites as an example, 48 satellites are in 6 tracks Upper operating, has 8 satellites on every track.In order to reduce the overlap of overlay area as far as possible, 8 satellites are made to be evenly distributed on track On, in order to the distribution in orbit with satellite is corresponding, earth surface is carried out into division (i.e. each point of eight equal portions according to latitude Area's dimension span is 45 °).Similarly, 6 tracks are made to be evenly distributed on longitude, earth surface is also enterprising in longitude accordingly The division (every track crossings east, the Western Hemisphere, each subregion longitude span be 30 °) of 12 deciles is gone, its earth surface is drawn Divide referring specifically to shown in Fig. 1.

After earth surface is divided into 48 ground subregions, be 48 ground subregions each allocation identification, this is designated Arabic numerals, Chinese character, English alphabet arbitrarily meet the character or mark of the embodiment of the present invention.In the embodiment of the present invention, with As a example by Arabic numerals, using the median point of the longitude and latitude of each ground subregion as the ground subregion center, then ground The center of subregion is as follows with the mapping table of mark：

It is corresponding to be respectively the schematic diagram that multiple ground subregions indicate mark, as shown in Figure 2.

Second step：The 3rd mark of the 3rd ground subregion that first user terminal is located is obtained, according to the 3rd mark, it is determined that The terminal partitions address of first user terminal；The Termination ID address of first user terminal is obtained, wherein, the end of first user terminal End ID addresses are fixed and uniquely；According to the terminal partitions address and Termination ID address of first user terminal, first user end is determined The address at end.

User terminal is addressed, the address of user terminal includes：Terminal partitions address and Termination ID address.Terminal point The mark of the ground subregion that regional address is located according to user terminal determines that the ground subregion being located in user terminal changes When, the terminal partitions address of the user terminal also accordingly changes.The Termination ID address of user terminal is different from for the user terminal The exclusive ID addresses of other users terminal, the Termination ID address of any user terminal is fixed and uniquely.

The address (equivalent to the IP address in cable network) of user terminal is by terminal partitions address and Termination ID address two Part collectively constitute, i.e. IDU=IDn+MACU, wherein, IDU for user terminal address, IDn be terminal partitions address, MACU For Termination ID address.The terminal partitions address of user terminal is the area code of the ground subregion residing for the user terminal, user terminal Termination ID address be the user terminal, the exclusive ID addresses of the other users terminal being different from addition to itself, any user The Termination ID address of terminal is fixed and uniquely, further, it is possible to the Termination ID address of user terminal is set as MAC Address (Media Access Control Address, physical address).Do not moved at a distance in user terminal and (referred to user terminal Not across ground subregion) in the case of, the address of the user terminal is to maintain constant.

In embodiments of the present invention, IPv4 (Internet Protocol Version can be continued to use in the address of user terminal 4, Internet protocol fourth edition) A class address formats, in 32 bit address, terminal partitions address accounts for 8, equivalent to the son in IPv4 Network No..Globally unique mark of the Termination ID address for user terminal.The scope of terminal partitions address is 0-127, wherein, IPv4 In address 0 and 127 are reserved address, are respectively used to represent all addresses and test winding.The actual model of terminal partitions address Enclose for 126 subnets, i.e., 126 ground subregions, namely 126 satellites between 1-126, can be represented.

3rd step：The first mark of the first ground subregion is obtained, the first mark is incorporated into into the address of the first satellite, obtain the One address, as the address of the first satellite first satellite in the first ground subregion.

First satellite obtains the first mark of the first ground subregion, the first mark is incorporated into the address of the first satellite, is obtained First address；First satellite stores the first ground subregion and the mapping relations of the first address in the mapping table of the first satellite； First satellite is obtained and according to the current longitude of the first satellite and latitude, it is determined that current first satellite is in the first ground subregion； Mapping table of first satellite according to the first satellite, when determining that the first satellite is in the first ground subregion, the address of the first satellite is First address.

The address of satellite includes：The map sub-region address of satellite.Over the ground interface of the map sub-region address of satellite for satellite, The mark of the ground subregion that the map sub-region address of satellite is located according to satellite determines, and the corresponding ground subregion of satellite changes During change, the map sub-region address of satellite also changes accordingly.

In order to the ground subregion that the satellite or a certain satellite that correctly find responsible a certain ground subregion are responsible for, need The mapping table between a satellite and ground subregion, the mapping table Satellite and ground subregion is maintained to be one-to-one.With by As a example by the MEO/LEO Satellite Constellation of 48 satellite compositions, 48 ground subregions can find itself mapping satellite at any time, And without repetition, 48 satellites can find the ground subregion itself being responsible at any time, and without repetition.Letter in the mapping table of satellite Breath includes：The first mapping relations between ground subregion and the address of satellite, and the low orbit that the satellite is located with the satellite defends Second mapping relations of other satellites in star seat.Wherein, the first mapping relations are used for the address for determining satellite, further Say, determine the map sub-region address (i.e. the interface over the ground of satellite) of satellite, to guarantee the communication over the ground of satellite.Second mapping relations For guaranteeing the communication of satellite and other satellites.

During the present invention is implemented, the division methods of ground subregion are given, identity and address are adopted to satellite and user terminal Detached form of presentation, effectively determines the address of satellite and the address of user terminal, be subsequent satellites with user terminal it Between communication provide technical support.

Preferably, the first satellite is obtained and according to the current longitude of the first satellite and latitude, it is determined that at current first satellite In the first ground subregion, including：

When satellite orbits, the earth also carrying out rotation with the angular speed of about 15 °/h (15 degree per hour), this One characteristic determines there is the relative motion of North and South direction between satellite and earth surface, between satellite orbit and earth surface There is the relative motion of east-west direction, model trajectory when satellite transit track has a drift angle with warp as shown in figure 3, wherein, R For the radius of the earth, the axis of rotation of the OA for the earth, OH are drift angle γ with angle formed by OA.In order to match ground square partition Case, finally makes mapping table reach one-to-one effect, needs to be modified the longitude of satellite.

Had according to the geometrical relationship in Fig. 3：

OO'=R × sin θ_w

O ' N=OO ' × tan γ

O'M=O'D=R × cos θ_w

OO'=R × sin θ_w

It is various according to more than to derive：

If satellite is in the Northern Hemisphere,

If satellite is in the Southern Hemisphere,

Wherein, θ '_jFor the longitude of satellite after amendment, θ_jTo correct the precision of front satellite,For ∠ DO'M, γ is ∠ O'ON, θ_wFor ∠ DOC be amendment before satellite latitude, and correct before and after satellite latitude it is constant.

Longitude and latitude of first satellite according to amendment, it is determined that current first satellite is in the first ground subregion.

By the amendment of pair warp and weft degree, it is possible to reduce the impact of the orbit inclination angle of low orbit satellite, the running track of satellite with Model trajectory when warp overlaps is as shown in figure 4, protosatellite running track (referring to the track CH in Fig. 3) is equivalent in Fig. 4 Track CA.

After revised satellite longitude and latitude is obtained, satellite place ground distributor can be determined by the longitude and latitude of satellite directly Area's (or referred to as corresponding ground region of satellite).But due to the two poles of the earth application condition that nearby longitude amendment is present significantly, make Certain two satellite can be caused in this way while being present in the situation of a subregion.Use now, by half bar track In (the Eastern Hemisphere section or the Western Hemisphere section of same track), the partitioning scenario of two satellites of low latitudes is derived on half track of same The partitioning scenario of high latitude satellite.For example：Referring to Fig. 5, the coordinate of 2, according to low latitudes No. 3 satellite can draw No. 2 satellites pair Answer No. 1 ground subregion, No. 3 satellite No. 3 ground subregions of correspondence.By ground subregion longitude and latitude relation and with the intersatellite position of rail Relation is put, No. 1 satellite No. 2 ground subregions of correspondence, No. 4 satellite No. 4 ground subregions of correspondence are can be inferred that.

The mapping table order of accuarcy of the satellite drawn using the computational methods of the embodiment of the present invention is higher, the road between satellite By matching degree it is also preferable.For example when the frequency for updating mapping table is one second one time, accuracy can reach 99.652%. But, may there is the mistake with about 431 seconds as cycle in the mapping table of satellite.It 431 seconds or so is precisely satellite north that reason is Can there is the corresponding mistake of very short time to the cycle for once being changed area due to the restriction of the reasons such as computational accuracy in the north. As this mistake period ratio is relatively fixed, this mistake can just be eliminated using the method for the mapping table for periodically updating satellite.

In embodiments of the present invention, by the longitude and latitude of amendment satellite, determine the corresponding ground subregion of satellite, it is ensured that Satellite and the one-to-one corresponding of ground subregion, by being calculated the corresponding ground subregion of satellite, take full advantage of satellite motion It is regular and periodically, effectively saved the limited memory space of satellite, and, in the case where customer volume is larger, meter Calculate caused time delay compared to generation of tabling look-up when postpone a meeting or conference, it is more advantageous.

In embodiments of the present invention, user terminal addressing is continued to use in the map sub-region address (interface over the ground of satellite) of satellite (such as IPv4 addresses), the calculating longitude and latitude (ground that itself longitude and latitude is located by satellite of itself of satellite periodically Subregion is used as itself corresponding ground subregion).Because satellite is constantly being moved relative to earth surface, when the longitude and latitude of satellite When the ground subregion that degree is located changes, start switching.The mapping table that satellite is maintained is searched during switching, corresponding ground point is found The information in area, changes the address of its interface over the ground, referring to Fig. 6, when satellite S1 moves to another ground subregion, can change The address of itself,So as to support the correspondence with foreign country of user terminal in the ground subregion.
