| Scene 2 | IP | TDM |
| Scene 3 | TDM | TDM |
| Scene 4 | IP | IP |
In this embodiment, for same physics BTS, corresponding two logic base stations on BSC: satellite station unit and units of ground station, the transmission link of two logic base stations are respectively satellite transmits link and terrestrial transmission link.Because the propagation delay time of satellite transmits link is obviously greater than the propagation delay time of terrestrial transmission link, need on BSC, finish the configuration effort of two logic base stations, promptly need satisfy the demand of satellite transmits to the parameter configuration of satellite station unit, parameter configuration to units of ground station need satisfy the ground transmission requirements, that is to say that the configuration parameter of two logic base stations is inequality.After configuration was finished, the transmission link of two logic base station correspondences was in case connect the state that just can be in work.
Certainly, under the general normal condition, all use the terrestrial transmission link to carry out transfer of data between base station and the base station controller, and do not use the satellite transmits link to carry out transfer of data, unless when the terrestrial transmission link down, be determining unit when determining that the ground transmission link interrupts, just can start the satellite transmits link and transmit data.That is to say that under normal circumstances, it is unimpeded that the terrestrial transmission link keeps.At this moment, the communication data between BSC and BTS transmits by the terrestrial transmission link.On BSC, show the units of ground station operate as normal.BSC and BTS not via satellite transmission link transmit any data.At BSC, the transmission link of satellite station unit interrupts, and can't work.
In case terrestrial transmission link down, system will automatically be switched to the satellite transmits link and get on, guarantee that communicating by letter between BSC and BTS can continue normally to carry out.According to the difference of switching the initiator, the concrete scheme of switching can be divided into BSC again and initiate transmission and switch and initiate transmission with BTS and switch:
Initiating transmission for BSC switches:
In present transmission link, system's (such as Operation ﹠ Maintenance System) moves a monitoring program, makes regular check on the on off operating mode of terrestrial transmission link; If detect the terrestrial transmission link down by monitoring program; to send the notice of terrestrial transmission link down to BSC; after BSC receives the notice of described terrestrial transmission link down; dodge the disconnected mistake that causes for fear of terrestrial transmission and switch, a protection timer can be set in monitoring program.In case monitoring program is found the terrestrial transmission link down, will start this timer at once.If behind the timer expiry, terrestrial transmission still is in interrupt status, and monitoring program will be notified BSC terrestrial transmission link down.
Certainly, also just monitoring program is installed on the base station controller, is detected the on off operating mode of terrestrial transmission link by monitoring program by base station controller.
After BSC received the notice of terrestrial transmission link down or detects the terrestrial transmission link down, transmission link issued to connect to BTS and sets up message (for example, the link setup frame of LAPD link) via satellite.After BTS received that message is set up in the connection of BSC, transmission link was replied via satellite.Like this, BSC and BTS incite somebody to action transmission link transport communication data via satellite.
At BSC, the transmission link of satellite station unit recovers, satellite station unit operate as normal, and promptly transmission link is switched and is finished.
Switch for the transmission that BTS initiates:
After BTS and BSC carried out data communication by the terrestrial transmission link, if the on off operating mode of BTS monitoring terrestrial transmission link after detecting the terrestrial transmission link down, dodged the disconnected mistake that causes for fear of transmission and switches, and BTS can start the protection timer.If behind the protection timer expiry, BTS finds that the terrestrial transmission link still is in interrupt status, and transmission link sends to connect to BSC and sets up message (for example, the link setup frame of LAPD link) via satellite.
After BSC received the request message that connects that BTS sends, transmission link was replied via satellite.Like this, BSC and BTS incite somebody to action transmission link transport communication data via satellite.
At BSC, the transmission link of satellite station unit recovers, satellite station unit operate as normal.So far, transmission link is switched and is finished.
Also see also Fig. 7, the structural representation of the application example 2 that provides for the embodiment of the invention.In this embodiment, comprise BSC71, BSC72 and BTS73, BTS73 links to each other with BSC72 with BSC71 with satellite transmits link 2 by terrestrial transmission link 1 respectively, that is: link to each other with existing network BSC71 by the terrestrial transmission link, and transmission link links to each other with emergent BSC72 via satellite.The networking scene of transmission link is as shown in table 1, specifically sees for details above-mentionedly, does not repeat them here.
Wherein, set up logic base station-units of ground station 711 of corresponding BTS73 on BSC71, the parameter configuration of units of ground station satisfies the requirement of terrestrial transmission; Set up logic base station-satellite station unit 721 of corresponding BTS73 on BSC72, the parameter configuration of satellite station unit satisfies the requirement of satellite transmits.Described units of ground station 711 links to each other with the first link startup unit 722, the first link startup unit 722 is used in terrestrial links just often, then utilizes the terrestrial transmission link between described first base station controller and the base station to carry out data communication according to the parameter of the terrestrial transmission link communication of described units of ground station Unit 721 storages; Satellite station unit 721 links to each other with the second link startup unit 722, wherein the second link startup unit 722 is used for interrupting at definite ground transmission link, notice such as the terrestrial transmission link down that receives the Operation ﹠ Maintenance System transmission, thereby determine that the ground transmission link interrupts, carry out data communication according to the automatic satellite transmits link that starts between described second base station controller and the base station of the parameter of the satellite transmits link communication of storing in the described satellite station unit.Under normal circumstances, BSC71 and BTS73 transmit communication data by terrestrial transmission link 1, show the units of ground station operate as normal on BSC71; And BSC72 and BTS73 not via satellite transmission link send any data, the transmission link that therefore is shown to the satellite station unit on BSC72 interrupts, can not work because of the transmission link fault in the satellite station unit.
But in case BTS73 detects the terrestrial transmission link down, system will automatically be switched to the satellite transmits link and get on, and guarantee that communicating by letter between BSC and BTS can continue normally to carry out.Concrete Switchover mechanism is identical with single BSC scheme with implementation procedure, also can be divided into two kinds that BSC initiates and BTS initiates.Concrete implementation procedure sees for details above-mentioned, does not just give unnecessary details at this.
Need to prove that the embodiment of the invention not only can be applicable to communication systems such as CDMA, UMTS, can also be applied to communication systems such as LTE.Satellite station unit in the embodiment of the invention and units of ground station also can be called units of ground station and satellite station unit.
