The base band system is also connected with a main station of the satellite, the small station serves as a bridge through the base band, and the small station has the functions of locking the satellite, transmitting signals and the like. The ACU software mainly stores parameters of a baseband system and satellite parameters. And then acting on the antenna and the transmission mechanism according to the parameters to search and lock the star of the antenna. The Modem mainly has the functions of storing basic information of the small station, demodulating satellite signals and demodulating high-frequency satellite signals into usable user signals. The basic information includes the serial number of the small station, the address of the small station, the SVN number which the small station turns on, and the like.
Since the satellite link and the system are relatively complex network systems, but at the small station end, the satellite finding and satellite parameter configuration for the satellite are stored by an OPT file, however, the OPT file is obtained by performing a series of configuration in a baseband system of the satellite, then exporting the OPT file, and then importing the OPT file into the modem again after exporting the OPT file, at this time, the same parameters are stored between the baseband system of the satellite and the small station, after the modem is started, the ACU interacts with the modem, and the ACU performs satellite finding, satellite locking and signal transmission according to the configured parameters. The signal arrives in the modem, which demodulates the signal and the user can then use the satellite network.
Based on this, as to the generating process of the OPT file in step S10, the invention provides a specific embodiment, and the generating of the OPT file includes the following steps:
s101, configuring hardware;
s102, configuring creatives;
s103, SVN configuration;
s104, configuring a small station port;
s105, coordinate information is configured, and a satellite coverage area is judged through the configuration of the coordinate information of the small station;
s106, configuring SSPC information of the terminal;
s107, selecting a terminal version;
and S108, finding the terminal needing to be configured everywhere.
In step S101, the hardware configuration includes adding a satellite route, adding a BUC, adding an LNB, adding an ACU, and adding a terminal type; wherein the content of the first and second substances,
the Satellite route is a modem model used by the configured small station; aiming at the types of modems of different manufacturers in the market, the performance of each type of modem is different, and different modems need to be selected;
the BUC and the LNB are used for configuring the BUC and the LNB used by the small station, the BUC carries out frequency conversion on the signals and amplifies the signals, and the LNB is used for reducing the signals and changing the frequency of the signals into an available frequency range;
adding ACU is to configure the ACU name and basic parameters of the small station; in the scheme, AIM (openamp protocol) is selected, TCP (transmission control protocol) connection is selected, and an antenna port IP address and a port number of the openamp connection are established by the input modem.
Adding a terminal type which is used for matching and combining the hardware configuration information; for a type defining a combination, for each antenna, the common antenna and the ACU are matched, but the modem can be matched, and multiple terminal types are possible for one antenna.
In step S102, all the default iDirect is filled in the creatives configuration, if different baseband system manufacturers can select other manufacturers, and if the configuration is wrong, the terminal can not access the network when the network is accessed; filling in the management IP address of the terminal according to the IP plan; to which user the terminal belongs (a small station may generally belong to a user group).
In step S103, the management and services of the small station are divided by SVN, and for the address of each SVN being different, the SAT0 address and the ETH0 address of each SVN are filled according to IP planning, where the ETH0 address includes a network number, a subnet mask, an effective time, an active/standby DNS, a DHCP gateway, a broadcast number, and an address field to be allocated by DHCP. For this reason, each SVN may function differently, such as SVN1 being a management SVN for access devices and SVN1745 being a VOIP for VOIP services.
In step S104, the port configuration of the small station is allocated for different SVNs; in the service scene using process, different services have different ports, so as to ensure that the ports are not in disorder. For example, the number of the SVN for accessing the internet is 3010, the port configured for the Modem of the small station is a port 3 for accessing the internet, and the number 3 port allocated in the system is 3010 SVN; when the user uses the device, the network cable is plugged into the 3 ports to carry out the internet access service.
In step S105, the satellite coverage area is determined, which is equivalent to GPS information, and for the mobile antenna, the GPS changes during the movement of the antenna, and the mobile antenna also automatically performs positioning, so that the mobile antenna does not need to be configured in this portion, and for the fixed antenna, the location information of the fixed antenna needs to be configured.
In step S106, the small station is configured individually through configuration of the SSPC information of the terminal. In the system, there are several configuration rules SSPP, and it is a certain class of small stations to which the rules apply, and there are some specific rules and configurations for a certain class of small stations. However, in the using process of the small stations, each small station has own using rule, and an appropriate SSPP template is selected, an SSPC-QOS rule is added, small station in-and-out-and-in QOS strategies are added in sequence, and the like, and then the SSPC is generated by applying the SSPP template to the small stations.
In step S107, the specific content of the terminal version selection: the firmware versions of the modems of a plurality of terminal small stations are stored in the system, and during the actual use of the small stations, only one version of the modem is used, so that the firmware version to be used needs to be configured on the system. The purpose is to keep the version used by the terminal small station consistent with the version on the baseband system.
In step S108, the content of Terminal _ OPT and Terminal _ lan _ OPT are copied into different TXT documents in the Retrieve Active Option File, respectively. Download global.pkg files inside NMS Management. And clicking Networks in the NMS Management, clicking a Retrieve Pending action File, exporting corresponding CONSTELLATION _ OPT, and copying the corresponding CONSTELLATION _ OPT in a newly-built TXT document, wherein four files are OPT files. (there are different files for different networks, such as 4 OPT files for Asia-Pacific network, 1 OPT file for E network, and 4 OPT files for global network)
Example 2
Referring to fig. 1 and 3, the present invention further provides a method for automatically switching a satellite link. This embodiment differs from embodiment 1 only in that:
in step S20, after the map files covered by the first satellite and the second satellite are stored in the satellite terminal device, the coverage areas of the first satellite and the second satellite are adjusted by user.
In this embodiment, a map file of the satellite coverage is stored, the coverage of each satellite is fixed, different satellites have different satellite coverage, and in the using process, a ship or a vehicle moves and inevitably moves out of the satellite coverage, so that a user who is not in the coverage cannot use a satellite network.
However, the coverage area is generally very large, for some users with short travel, the satellite range cannot be found in the moving process, the map file can be specified very small by using the method, for example, the satellite coverage area is the whole China, but for one user, the map file is only used in Guangdong province and cannot be used in other provinces, the map range of the Guangdong province can be specified, as long as the user finds out the Guangdong province and detects that the GPS of the user is not in the range, the equipment can automatically cut the satellite according to the OPT file, the resource of the first satellite cannot be used, and the resource of the second satellite can only be used.
Meanwhile, the high-flux satellite is multi-beam coverage at present, for example, there are three beams in the satellite, the coverage area of each beam is different, if a user only specifies that the resource of beam 1 is used in beam 1, and the resource of the second satellite is used in beams 2 and 3, at this time, the device is adopted, the map range file of beam 1 is stored in the device, and when the user moves in a range outside beam 1, the device can automatically switch to the second satellite, so that the user uses the resource of the second satellite.
The traditional switching strategy and algorithm generally aim at certain specific scenes, have fixed parameters and models, and have fixed satellite coverage, and cannot provide communication service for a variety of service switching scenes. Furthermore, during the continuous communication process of the terminal, especially when the link changes or jitter occurs, some index parameters and terminal-related parameters in the satellite mobile communication system may change dramatically, and the changes of these parameters may result in that the handover strategy being executed is no longer suitable. How to adjust the switching strategy and the parameter values thereof according to the constantly changing external parameters is a major challenge to timely and effectively respond to the change of the related parameters.
The self-adaptive switching algorithm can automatically adjust the switching strategy and the parameter values thereof under different scenes, provide reliable communication service for the terminal as far as possible, reduce the service cost and provide the utilization rate of satellite communication.
The invention discloses a method for automatically switching a high-throughput satellite network and a traditional satellite network, which solves the problem that various existing satellite links and a ground network are independent from each other and can not be mutually fused and communicated; the user can communicate with the outside world at any place and any time, and can make intelligent link judgment according to different service types and select the most economical and practical link most suitable for the current service type. The integration of the high-flux satellite and the traditional satellite can realize complementary intercommunication with the ground cellular communication, and can break through the dependence of wireless connection on the ground network and promote the better development of the ground network through competition.
The method of the invention comprises the following advantages: 1. the switching between the high-flux satellite and the traditional satellite is completely automated, manual participation is not needed, the traditional network access process is simplified, and the complicated process of manual network access is realized; 2. for the satellite in the stationary orbit, the fixed coverage range is provided, the communication coverage range can be defined in the coverage range by user, and the diversity of the service is improved; 3. the coverage area of the satellite and the global network of the earth orbit satellite chain can be switched randomly; 4. storage analysis can be carried out on the switched log data; 5. the satellite link locking function can be realized in the coverage range; 6. there is no signal or occlusion for the first satellite network. The method can judge the coverage area of the second satellite network to switch according to the parameters of the second satellite network, thereby ensuring the communication reliability; 7. for the situation that the first satellite communication resource is limited, the satellite link with sufficient second backup satellite communication resource can be switched. Ensuring the communication quality.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
