Manner and the device by this invention regard manner and the system which retain electricity with the especially radio data transmission system in regard to the communication by the mobile device which possesses the multiple transceivers.
This application has been based on the American provisional patent application 60/913,153rd number bill of 2007 April 20th application which it is related to the American provisional patent application 60/908,289th number bill of 2007 March 27th application, we obtain the benefit of that application day, these contents are referred respectively here.

As for figure 1A allocation of the channel in the satellite spot beam has been shown. As for the satellite system which operates with the many spot beam it is possible to reuse frequency. As for each spot beam of the many spot beam being the satellite system, available barely only proportion among the entire spectra it is possible to be disposed. For example if the entire effective spectrum 10MHz (in the terrestrial anti-satellite segment 5MHz) is in 5MHz and the air to ground segment, if and the satellite is uses 10 spot beam reuse patterns, 0.5MHz (namely 5MHz/10) you can use the optional specified beam. For example the satellite large number (if exceeds 200) the spot beam is used, the satellite the radio spectrum before using up, is a possibility electricity constraining.
The satellite spot beam transceiver can transmit the data over the many channel. As for each channel it is possible to possess the frequency which is allocated. According to 1 execution configurations of this invention, as shown in figure 1A, it can transmit the transceiver A and B, C, D over the optional four channels which the label are attached respectively. Of course, it is possible to be able to give the channel of optional number. For example in down link state, from the satellite transceiver the mobile device (MD) to as for communication it is done by one among these channels like channel A.
With communication link to the satellite, the mobile device (MD) the data is transmitted to the satellite transceiver from the ground of uplink. With this data transmission, with the execution configuration which is shown in figure 1A, A1, B1, C1 and D1 four possible channels 12 which the label are attached respectively exist. Channel A1 corresponds to the aforementioned channel A. Namely channel A and A1 form channel opposite. When you rephrase, channel A from the satellite (namely down link) points to the half of the channel which is used in order to transmit the data to the terrestrial terrestrial device. With another side channel A1 from the terrestrial device (namely uplink) points to the other half of the channel in order to transmit the data to the satellite. In the same way, this is the same even with remaining channel opposite B/B1, C/C1 and D/D1.
With communication link to the ground, as for the satellite transceiver the signal the mobile device (MD) to can be transmitted from the satellite. Communication to the ground the mobile satellite system (MSM) may be part from the satellite. As for communication link to the ground it is possible from the satellite to be called mobile satellite system communication down link. With communication link to the satellite, as for the mobile device the signal can be transmitted to the satellite transceiver from the ground. As for link of the satellite it is possible from the ground to be called mobile satellite system communication uplink. With communication link of the mobile device, as for base station the signal can be transmitted to the mobile device from base station. With communication link of base station, as for mobile station the signal can be transmitted to base station from the mobile device.
As for figure 1B allocation of the channel in the satellite spot beam due to 1 execution configurations of this invention has been shown. With this execution configuration, as for the channel of 1 or more of multiple channels 34 at the time of down link transmitting that it can be used the satellite (S) the channel and/or the earth (T) either of the channels. As for multiple channels 34 they are 2 down link S/T channels which can make that both of the satellite transceiver and base station communicate to the mobile device with the channel of 1 or more of multiple channels 34 possible. Furthermore, to include the multiple uplink satellite channels it is possible data transmission uplink 36 with the reuse of the identical channel.
Multiple earth OOB (T OOB) as shown in figure 1B, to be added to data transmission link 36 it is possible uplink channel 38. Each T OOB uplink channel 38 without interfering to the reception by the satellite transceiver makes that the mobile device communicates with base station possible. As for the T OOB spectrum in order to raise spectrum efficiency by making that it is used depending upon the earth station where the satellite spot beam down link identical channel operates under the identical channel spot beam possible, it is possible to be constituted. Each one of the multiple down link T channels of multiple duplex S/T channels 34 and also the terrestrial T OOB channel of the multiple uplink T OOB channels form the terrestrial channel opposite which allows the communication with base station and the mobile device. With the execution configuration which is shown in figure 1B, as for the OOB spectrum part 38 it consists of four T OOB uplink channels, each four T OOB uplink channels make the respective channel and opposite of four down link T channels of 2 down link S/T channels. The structure which possesses four channels is shown, but the fact that the channel of optional number can be constituted should be recognized. Because the uplink T OOB channel is not seen by the satellite transceiver, interference is lightened. Uplink T OOB channel 38 is outside passing band of the satellite transceiver. If there is no this configuration, terrestrial use of the same channel as the satellite spot beam of the identical channel is not unable to be connected to the interference with the uplink identical channel and the satellite which make opposite. It is given with patent application of the related simultaneous continuation application where this kind of manner and detailed demonstration of the system depend on Agent bill 028780-P0003 and entitle Method and System for improving the Spectral Efficiency of a Data Communication Link, this is made the references with this application.
And to be added it is possible also multiple electricity OOB down link channels 40. Because with terrestrial - satellite communications as for electricity of most of the satellite it is used for air to ground segment transmission, addition of electricity OOB down link can save the electricity of the satellite. As for terrestrial - satellite segment transmission the channel 36 which is allocated to the satellite can be used. Use electricity OOB address does down link pass. The electricity OOB spectrum 40 which possesses the electricity OOB channel 42 of 1 or more from base station is used for the transmission of the mobile device. As for the base station where series is located strategically it is possible to be constituted in order to do the transmission dedicated displacement of the satellite of a certain area. As for each electricity OOB channel 42 of electricity OOB channel 40 of 1 or more it is possible displacement vis-a-vis the down link satellite S channel of the multiple down link S channels of duplex S/T channel 34. In order for four electricity OOB channels to be used in figure 1B, it is shown, but the electricity OOB channel of optional number can be used. As for the number of electricity OOB channels as for the necessity to agree to the number of spot beams of spot beam reuse pattern or the number of down link S channels of duplex S/T down link channel 34 it is not. For example with the smallest configuration, the same electricity OOB channel namely one electricity OOB channel can be used all spot beams (spot beam 1 and spot beam 2 and the like) with. Furthermore, for example with 1 configurations, the same electricity OOB channel it can be used with the respective multiple S channels of the duplex S/T channel. Portion of the optional spot beam or entire down link traffic can unload from satellite down link, it is possible to be treated to substituting by the terrestrial base station transmitter. As for these base stations as been desire, it is possible to be categorized to the optional place inside the spot beam footprint of the satellite. The satellite transceiver can save electricity with this. Electricity of the satellite after that to be able be used in order support the other communication channel, therefore entire capacity of telecommunication network it augments.
As for the user which carries the mobile device, it is possible support terrestrial based down link pass (electricity OOB channel 42 in multiple electricity OOB channel 40) with satellite based uplink pass (the S uplink channel in multiple S channel 36) by. Terrestrial down link namely the electricity OOB channel time synchronization can be done in order to interpose to the signal which appropriate delay was transmitted vis-a-vis the satellite, in order to consider the time delay which is related to propagation delay with that furthermore over the distance which is related to the uplink pass the long satellite support appropriately time is shifted.
The normal mobile satellite system (MSS)/the auxiliary terrestrial component (ATC) as for canonical mode, the channel which is not used by the satellite transceiver can be used for the communication of the base station anti- mobile device inside one spot beam of the satellite transceiver it is stipulated, (as for ATC also TMA should pay attention to being called,). Therefore, some channels, for example channel B, C, as for D following to MSS/ATC canonical mode, it can be used as a terrestrial channel, for example as the ATC/TMA channel for communication of base station and the mobile device.
Figure 1C has shown the channel allocation of the satellite spot beam of the MSS/ATC system due to another execution configuration of this invention. Following to MSS/ATC canonical mode, for example as for the multiple channels of 1 or more the MSS channel or the terrestrial down link channel (it can be used with down link transmission 14 the ATC channel) as. For example as for one channel 16 it can be used as the duplex MSS/ATC channel. For example as for remaining channel 18 the terrestrial channel (the ATC channel) with it can be used. Furthermore following to the reuse of the identical channel, for example as for uplink 20 of the data transmission alteration the terrestrial channel (it is possible to include MSS channel 22, the ATC channel) in addition to 24.
Resembling to the execution configuration which is shown in figure 1B, in order use of satellite electricity decrease or to make smallest, for example outside band (OOB) as for the spectrum the complementary type terrestrial system (ATC/TMA or TME) the satellite anti- terrestrial part of MSS (the down link part of MSS) it can be used for substituting. As for the OOB spectrum it is outside the spectrum which is allocated for MSS/ATC use. The OOB spectrum is the spectrum part which is the possibility of being equal to the spectrum allocation of the optional channel which was transmitted with data transmission link. Can the same OOB spectrum be used with the optional spot beam from the satellite transceiver. For example as for the OOB spectrum it is possible to include the optional spectrum which possesses the appropriate propagation feature for mobile or carrying possible use.
As shown in figure 1C, ATC OOB uplink channel 26 is added to data transmission link 20. ATC OOB uplink channel 26 without interfering to the reception by the satellite transceiver makes that the mobile device communicates with base station possible. As for the ATC OOB spectrum in order to raise spectrum efficiency by making that it is used depending upon the earth station where the satellite spot beam down link identical channel operates under the identical channel spot beam possible, it is possible to be constituted. If there is no this structure, as for the spot beam of the identical channel satellite or terrestrial use of the same channel interference with the uplink identical channel and the satellite which make opposite is not unable to occur.
As shown in figure 1C, because with terrestrial - satellite communications, as for most electricity of the satellite it is used for nul - area segment transmission, also electricity OOB down link channel 28 is added. As for terrestrial anti-satellite segment transmission it can use the spectrum which is allocated to the satellite. Use of electricity OOB address does down link pass. Electricity OOB spectrum 28 is used for base station anti- movement device transmission. As mentioned earlier, with the constraint of facilities appropriation, as for the satellite we are limited the entire electric energy which is allocated to communication, most of the electricity which is consumed reverts to the transmission electricity which is related to the operation of the transmitter support down link communication. By forming the base station where the series which does the transmission dedicated displacement of the satellite of a certain area is located strategically, portion of entire down link traffic of the optional spot beam can unload from satellite down link, it is possible to be treated to substituting by the terrestrial transmitter. As for these base stations, it is possible to be categorized to the optional place inside the spot beam footprint of the satellite by desire. For example as for these base stations it is possible to be categorized to ACT/TMA or ACT/TMA or TME area of the position where TME base station is located. Base station can also be located the cover range of the area which encircles TPC/TMA area in order to augment becoming independent in the high post. To however, or furthermore, furthermore it can operate the transmitter by high electricity. Augmentation of the cover range saves satellite electricity. It transmits these base stations at electricity OOB spectrum 28. It makes that the satellite transceiver which electricity is saved retains electricity possible with this. Electricity of the satellite after that to be able be used in order support the other communication channel, therefore entire capacity of telecommunication network it augments. But, instead of using electricity OOB spectrum 28 in order displacement the transmission dedication of the satellite of a certain area, the ATC channel interference is dying enabled, if is, it can also be used. But, the ATC spectrum is used for strengthening the terrestrial capacity mainly. Detail to the narrow channel where it can augment the use of the OOB spectrum it possesses relatively high electricity to be split it is possible terrestrial cover area. Because the addition electricity drain to the satellite which is related to reception does not exist, the satellite continues support the uplink part of the communication channel. Therefore, the mobile device which the user carries is support with terrestrial based down link pass and satellite based uplink pass. Terrestrial down link can be done in order to interpose in the signal which appropriate delay was transmitted time synchronization in the satellite, the time delay which is related to propagation delay with that over the distance which is related to the uplink pass the long satellite support in order adaptation, appropriately time is shifted.
Drawing 2 has shown the hand off boundary between MSS mode, TPC mode, ATC/TMA mode and the TME mode due to 1 execution configurations of this invention. As shown in drawing 2, spot beam 116 irradiates the area which surrounds mobile device 106. Inside this area, four communicate modes which can communicate with mobile device 106 satellite transceiver 102 bidirectionally (MSS, TPC, ATC and TME) exists. In the same way, with some areas among this areas, to communicate with mobile device 106 bidirectionally it is possible base station 104.
MSS mode area 302 is the area which can communicate with satellite transceiver 102 mobile device 106 bidirectionally. With MSS mode area 302, as for mobile device 106 it is outside the range of base station 104. ATC mode area 306 and TME mode area 304 mobile device 106 base station 104 or is the area which can be communicated with satellite transceiver 102. Furthermore as for drawing 2 mobile device 106 the hand has shown also the various boundaries which are turned off between various modes.
As for MSS mode following to normal MSS canonical mode, satellite transceiver 102 communication (namely MSS communication down link and uplink) through satellite transceiver 102 at portion of the radio spectrum which is allocated it has communicated. For example when there is a possibility earth station communication with the base station 104 without being possible, MSS mode can be used. In order to prevent the spot beam interference which it adjoins can the channel which is used with the spot beam which it adjoins to satellite spot beam 116 be controlled by normal rule.
(Also TMA is called) as for ATC mode mobile device 106 through terrestrial base station 104 inside spot beam 116 of satellite transceiver 102, points to the mode which has been communicated. The spectrum using normal MSS/ATC canonical mode, from terrestrial base station communication link of the mobile device and/or is allocated to both of communication link of terrestrial base station from the mobile device. For example as for the channel it is possible, as for the remaining channel can be used with terrestrial communication to be allocated to satellite communications.
As for TME mode, mobile device 106 using normal MSS/ATC canonical mode, outside the band which is not portion of the spectrum part which is allocated to the MSS communication link for base station communication link from the spectrum and the addition mobile device which are allocated to the MSS communication link for communication link of the mobile device from the spectrum and the addition terrestrial base station which are allocated (OBB) using the spectrum, through terrestrial base station 104, it points to the mode which it communicates.
TME mode area ATC/TMA mode area 306 with 304 and MSS mode area 302 down link from the satellite transceiver of TME mode area 304 using the channel which is shared, in the mobile device 106 which receives communication from base station 104, before mobile device 106 enters into MSS mode area 302, following to MSS/ATC canonical mode, makes the channel change which is not used for satellite communications. Here, the cover range of ATC/TMA mode is supposed that it is larger than the cover range of TME mode. Namely, TME mode makes the utilization of many channels possible. In this case, ATC covers the optional specified geographical area which covers by TME.
Terrestrial electricity conservation (TPC) as for mode area 308, at the same spectrum as the spectrum which can transmit the mobile device with MSS mode can transmit (from the mobile device to satellite uplink) it points to the mode which. (It can use OOB where it can allocate) terrestrial base station of base station to the down link of the portable device because of electricity. When mobile device 106 arrives in cover boundary of TPC cover area 108, from MSS mode the hand it is turned off to TPC mode. When hand off occurs, there is no interference between MSS mode and TPC mode. Furthermore even before the hand off, because mobile device 106 transmission/has received with MSS mode area 302, interference does not exist.
Furthermore, just one part of the terrestrial anti-satellite link section of the spectrum is used for frequency reuse with optional specified spot beam 116.
Figure 3A3C furthermore has shown the hand off concept between MSS and TPC in detail with 1 execution configurations of this invention. Way it is shown in figure 3A, for example for example with uplink MSS mode, as for channel 1 portion of the spectrum (uplink channel 1) be able to use, as for channel 2 another part of the spectrum (uplink channel 2) you can use. For example for example with down link MSS mode, as for channel 1 portion of the spectrum (down link channel 1) be able to use, as for channel 2 another part of the spectrum (down link channel 2) you can use. As explained with paragraph ahead, the electricity OOB down link channel is added to down link MSS in order to save the electricity of the satellite. Therefore, with TPC mode, as for the electricity OOB channel spectrum it is used in order support down link communication. As for the OOB channel spectrum channels 1,2 of an optional quantity which is limited only with the size of each channel and the entire spectrum. It is possible to possess K.
For example as before the hand off between MSS and TPC, shown in figure 3B, when the mobile device is moving with MSS area, as for uplink channel 1 it can be used for the communication with the mobile device and the satellite transceiver in uplink direction. In the same way with MSS mode, before the hand off with MSS and TPC, the satellite transceiver with down link direction and being used for the communication between the mobile devices can do down link channel 1. From MSS hand off to TPC mode the same uplink channel, for example in figure 3B maintains uplink on uplink channel 1, just down link the hand is turned off to TPC earth station. But if down link joint to the satellite is maintained after the hand turning off, as furthermore demonstrated with paragraph below, it is possible furthermore to give obstinate Characteristic to communication pass, with the loss of the capacity with the repetition of communication as a sacrifice.
After the hand turning off, way it is shown in figure 3C, for example from the satellite as for down link to the mobile device with TPC mode the electricity OOB spectrum (OOB channel 1) to the hand it is turned off, overwrapping with the MSS spectrum does not exist. In addition, electricity OOB channel 1,2. As for K as for the necessity to agree to the number of spot beams of spot beam reuse pattern you pay attention to without being. Actually, with the smallest configuration, as for the same electricity OOB channel possessing the case of some interferences in the geographical edge of the spot beam, all spot beams (spot beam 1 and spot beam 2 and the like) with it can be used. Other direction (namely the hand off mode of MSS) with, converse occurs from TPC.
Furthermore be able to operate the TPC transmitter by high electricity, therefore when ATC and/or being disposed at the same base station which uses TME, furthermore it to be possible to possess the satisfactory cover footprint, because the satellite is used because the TPC system does uplink support, to not encountering to the same terrestrial cover limitation of mobile uplink pass should be noted. In normal ATC or the TME system, as for electricity cover area of base station, is limited in only the cover area which gives the footprint of the cover area which is equal to implementation possible distance due to the uplink device which electricity is limited.
With example of this system usage, the same parameter (module channel protocol and encoding etc) is used. But as for these parameters as for the necessity to be the same it is not. In order to be desired by the system designer, to be chosen it is possible these parameters.
When MSSTPC hand off is done, satellite electricity is saved. The same thing, it is possible to be implemented by ATC and TME. But, as (shown with example of drawing 2,) the big opportunity which saves satellite electricity because of the geographical footprint where TPC is expanded exists. Furthermore, this can also make the possibility of interference between TME, ATC/TMA and MSS mode decrease very. Terrestrial transmission to be shifted by electricity OOB with down link direction, because the same MSS channel is maintained for transmitting with uplink direction, possibility of interference between TME, ATC/TMA and MSS mode is decreased. To be the sequence of MSSTPCATCTME it is possible hand off process. But as for hand off process it is possible to be the sequence of optional sequence, it is not necessary to be this sequence.
With other direction, in order for the mobile device to leave from terrestrial cover area, while moving, as for hand off opposite direction (namely TMEATCTCPMSS) there is a tendency which is.
The aforementioned execution configuration has used the satellite transceiver, but to be applied to the network structure where the optional transceiver like the terrestrial transceiver is used it is possible the manner which shifts down link transmission in the channel of the electricity OOB spectrum. This kind of transceiver some electricity constraint, namely electricity can possess the transceiver which constrains. As for electricity conservation at terrestrial base station it is not big problem different from the satellite transceiver, it prevents high position or smallest capacity and interference from the overlay cover area which possesses electricity constraint, but for example like the satellite, it can use the same concept in order to give the geographical buffer.
Drawing 4 has shown mobile device and the communication structure with of the satellite transceiver and base station with 1 execution configurations of this invention. As shown in drawing 4, satellite receiver SR and being bidirectional, it can communicate mobile device MD. For example with uplink direction, as for mobile device MD (using the optional channel of the spectrum like uplink channel 1,) using the uplink satellite channel with MDD mode, it can communicate with satellite transceiver SR. For example in the same way, with down link direction, as for the satellite transceiver (using the optional channel of the spectrum like down link channel 1,) using the down link satellite channel with MDD mode, it can communicate with mobile device MD. Furthermore, it can communicate mobile device MD with base station BS. For example with uplink direction, as for mobile device MD using the terrestrial channel, (with MSS/ATC mode using the optional other channel of the spectrum which is not used for the communication with the mobile device and the satellite transceiver, namely channel 2,3. Using N, it communicates) it can communicate with base station BS. With down link direction, using the optional available OOB channel, it can communicate with mobile device MD base station with TPC mode. But, in place of the OOB channel, the ATC channel is enabled, if is, or it is desirable to save the OOB channel for using the other things, is, the normal ATC channel can be used. With this example, mobile device MD it is supposed that it has been categorized to the area which covers by the beam spot 1 of the satellite transceiver. But when the mobile device covering by the optional other beam spot of the satellite, the same analysis can be done.
With this execution configuration, as for mobile device MD in order poly modes (MSS, ATC and TPC) with to receive and to transmit the data and it is constituted. Mobile device MD through MSS uplink and the down link channel, receives the data from satellite transceiver, SR transmits the data to there, through MSS uplink and the OOB channel, to base station BS transmits the data, in order to receive the data from there, is constituted. As a result, for example as for mobile device MD the MSS down link channel (MSS down link channel 1) through, it receives the redundant data from satellite transceiver, SR through the OOB channel, it is possible to receive from base station BS. For example in the same way the mobile device the MSS uplink channel (MSS uplink channel 1) through, the same data set of the data can be transmitted to satellite transceiver SR, for example the MSS uplink channel (MSS uplink channel 2) through, the same data set can be transmitted to base station BS. This way, network redundancy and it is possible, furthermore obstinacy give entire network for frequency diversity to be implemented.
Furthermore, another feature of this execution configuration furthermore offers data security by splitting the data set into the sub data set of 2 or more, the sub data set of 2 or more is to be transmitted by MSS mode and TPC mode. For example as for the 1st sub data set, it to be possible to be transmitted over MSS mode. To be transmitted by TPC mode it is possible the 2nd sub data set. For example as for the aforementioned network structure the strategy which needs redundancy or with urgent service communication, or it can be used with the sensitive data communication which needs the security of the data.
With TPC mode, to be shared from the adjacent spot beam it is possible the MSS uplink spectrum (furthermore you can mention earlier and as shown in figure 1A, you can use systematic ATC OOB). When you access figure 1B in the same way, as for the uplink S channel it is possible, or 1 or also the multiple T OOB channels can be used to be shared from the adjacent spot beam.
Drawing 5 the mobile device and, has shown the flowchart which shows the manner which is communicated with the 1st transceiver and the 2nd transceiver with 1 execution configurations of this invention. The 2nd transceiver has been categorized to the area which covers from the 1st transceiver by the spot beam. 1st it is received 1st from the transceiver by the mobile device the signal has the energy whose 2nd it is received 2nd from the transceiver by the mobile device is lower than the signal. With this manner it is transmitted from the 1st transceiver to the mobile device in at least one of the multiple channels in step S202. With manner it transmits to the mobile device from the 2nd transceiver with the channel outside the multiple channels furthermore in step S204. With 1 execution configurations of this invention, as for manner the step which at least is transmitted to the 1st transceiver from the mobile device with one which the 1st transceiver transmits to the mobile device furthermore in step S206 channel is included. With 1 execution configurations, as for the 1st transceiver it is the transceiver which constrains the electricity like the satellite transceiver, the 2nd transceiver is base station.
