Road.
Mobile terminal can also be in different satellites using one number under different satellite networks under this system
Different numbers is used under network.
Resource allocation server can make each mobile terminal in different satellites according to the physics number of each mobile terminal
The same number is only used under network, and mobile terminal can also be managed collectively by the physics number of mobile terminal in different satellite networks
Jack per station under network shows that same mobile terminal has different numbers (2 numbers under different satellite networks in following table
Code), it is managed collectively according to physics number by explorer, no matter dials which number can be connected.
Resource allocation server mobile terminal log-on message
The number that mobile terminal is registered under different satellite networks in table is number 1 and number 2 respectively；Scheduling of resource takes
The up-to-date information that device obtains of being engaged in is that number 1 is in off-line state, number 2 is online.Come when intelligent exchange receives
It is mobile terminal number 1 from the call request of terrestrial communication networks, at this moment intelligent exchange is dispatched by IP network query resource
The log-on message of server, according to log-on message, 1 calling of checking numbers is transferred to number 2, and number 2 is connected online, is established logical
Believe channel；It is mobile terminal number 2 when intelligent exchange receives the call request from terrestrial communication networks, at this moment intelligence is handed over
The log-on message changed planes through IP network query resource dispatch server directly calls number 2 according to log-on message, and number 2 exists
Line is connected, and communication channel is established.In this way when same mobile terminal has jack per station under different satellite networks, caller need not close
Network where the heart is called, no matter call which number can intercommunication, and then improve call completion ratio.
In addition, the mobile terminal log-on message and channel allocation information in resource allocation server can also be by broadcasting altogether
It enjoys on intelligent exchange or network control center, intelligent exchange is by inquiring the channel distribution on intelligent exchange or network control center
Information and mobile terminal log-on message, obtain called routing iinformation.But exist in this case and resource allocation server
Data synchronize problem, generally by mobile terminal log-on message come trigger resource allocation server send location update message
The update of information of mobile terminal in local data base is realized to Relational database, wherein local data base can be deployed in solid
Surely in the intelligent exchange stood or network control center.
Preferably, the terrestrial communication networks are PSTN network, and the PSTN network passes through E1 networks and intelligent exchange
Connection.It is apparent that terrestrial communication networks can also be mobile communications network.
Preferably, the channel terminal is TDMA channel terminals or FDMA channel terminals.
A kind of intelligent satellite communication means of IP based network and E1 networks comprising step：
S10, the log-on message that the channel terminal of fixed station passes through satellite reception mobile terminal；
S20, the channel terminal that resource allocation server is connected and fixed station obtains and the log-on message of memory mobile terminal；
S30, when calling occurs and mobile terminal is as being called, the intelligent exchange query resource dispatch server of fixed station
In mobile terminal log-on message and channel allocation information, and established according to mobile terminal log-on message and channel allocation information logical
Believe channel.Preferably, the mobile terminal log-on message include mobile terminal physical number, mobile terminal state, herd number and
Number status information.
Preferably, the step S30 includes sub-step：
S31, the intelligent exchange in fixed station pass through IP network connection resource dispatch server and inquire log-on message；Or
S32, the intelligent exchange in fixed station pass through network control center connection resource dispatch server and inquire log-on message；Or
S33, resource allocation server broadcast registration information notify the intelligent exchange in fixed station.
Can in advance in resource allocation server memory mobile terminal channel allocation information, the channel allocation information packet
Include the log-on message (letters such as mobile terminal physical number, mobile terminal state, herd number and number status information of mobile terminal
Breath).When calling occurs, after intelligent exchange receives call request, the called registration in query resource dispatch server and channel
Information is distributed, and communication channel is established according to the content of channel allocation information.
Resource allocation server can make each mobile terminal in different satellites according to the physics number of each mobile terminal
There are one numbers for lower of network, and mobile terminal can also be managed collectively by the physics number of mobile terminal under different satellite networks
Jack per station, show in following table, same mobile terminal has different numbers (2 numbers) under different satellite networks,
It is managed collectively according to physics number by explorer, no matter dials which number can be connected.
Resource allocation server mobile terminal log-on message
The number that mobile terminal is registered under different satellite networks in table is number 1 and number 2 respectively；Scheduling of resource takes
The up-to-date information that device obtains of being engaged in is that number 1 is in off-line state, number 2 is online.Come when intelligent exchange receives
It is mobile terminal number 1 from the call request of terrestrial communication networks, at this moment intelligent exchange is dispatched by IP network query resource
The log-on message of server, according to log-on message, 1 calling of checking numbers is transferred to number 2, and number 2 is connected online, is established logical
Believe channel；It is mobile terminal number 2 when intelligent exchange receives the call request from terrestrial communication networks, at this moment intelligence is handed over
The log-on message changed planes through IP network query resource dispatch server directly calls number 2 according to log-on message, and number 2 exists
Line is connected, and communication channel is established.Calling subscribe need not be concerned about which satellite network called subscriber is registered under in this way, no matter call
Which number can be connected, and then improve call completion ratio.
Mobile terminal log-on message can also be stored in fixed station or network control center, pass through broadcast by resource management server
Update, but this method has that data are synchronous between resource allocation server and fixed station and network control, it is general logical
It crosses mobile terminal log-on message and sends location update message triggering scheduling of resource and realize local data base to Relational database
The update of middle information of mobile terminal.
The intelligent satellite communication system and method for a kind of IP based network of the present invention and E1 networks are by exchanging fixed station
Machine is transformed and upgrades, and makes itself and resource allocation server connection communication, realizes satellite communication system resource-sharing, realizes and moves
Dynamic termination number uniquely deployment or unified management so that when mobile terminal is used as called, call completion ratio greatly improves.In addition, intelligence
Interchanger increases IP network and E1 network communications, it is made to have mobile management function so that expires while system structure is simple
The demand of sufficient scheduling of resource.
It is to be illustrated to the preferable implementation of the present invention, but the invention is not limited to the implementation above
