In a first aspect, an embodiment of the present application provides a satellite terminal-based communication method applied to a ship end 100.
In some embodiments, referring to fig. 2, a flowchart of a satellite terminal based communication method in an embodiment of the present application is shown. The method specifically comprises the following steps:
s110, acquiring a preset first mapping identifier and a connection state according to communication connection established with a satellite terminal;
s120, sending the connection state to a satellite station so that the satellite station can adjust a communication strategy according to the connection state, wherein the satellite station is used for being in communication connection with a shore base end;
and S130, performing communication connection with the shore base terminal according to the adjusted communication strategy and the preset communication request.
It should be noted that, in the embodiment of the present application, the ship end 100 is communicatively connected to a satellite terminal of an FDMA communication network, the FDMA communication network is communicatively connected to a satellite station 300, the satellite station 300 is communicatively connected to a shore base end 200, and in step S110, the ship end 100 obtains a first mapping identifier of the communication connection and a current connection state between the ship end and the satellite terminal, that is, a network access state, through the communication connection established with the satellite terminal in the FDMA communication network 400.
In some embodiments, in step S110, the ship terminal 100 acquires, according to the communication connection established with the satellite terminal, a first mapping relationship with a port of the satellite terminal, a second mapping relationship between an initial communication request of the ship terminal 100 and a preset communication request, a third mapping relationship between the communication request and the port of the satellite terminal, and a connection state between the current ship terminal and the satellite terminal, where the first mapping relationship refers to a mapping relationship between an FXS port of the satellite terminal and a port FXO of an access gateway of the ship terminal 100 as shown in fig. 1; the initial communication request of the ship end 100 refers to a main call number used for calling the shore base end 200 at the ship captain as shown in fig. 1, the main call number is a communication number inside the ship, and the preset communication request refers to a call number received by the shore base end 200 and is provided for the shore base end 200 or other ships to make a call or determine the identity of the ship end 100 making the call instead of the communication number inside the ship; the third mapping relation between the communication request and the port of the satellite terminal comprises two conditions, wherein one condition is that when the communication request comes in from the port of the satellite terminal, the hotline number of the port of the satellite terminal is the ship internal communication number corresponding to the ship user, and the second condition is that when the communication request comes out from the port, the ship user corresponding to the ship internal communication number has the authority of using the port to carry out relay calling.
On the other hand, the second management server at the shore-side 200 issues the connection relationship between the FXO interface of the satellite terminal and the FXS interface of the satellite relay gateway to the satellite relay gateway of the satellite station 300, and issues the mapping relationship between the one-number-for-one-number of the ship user and the port number of the FDMA satellite terminal to the soft switch server, where the configured port number is the telephone number corresponding to the FXS port with the same port number at the satellite terminal of the ship-side 100.
In step S120, the ship terminal 100 sends a connection status of communication connection with the satellite terminal to the satellite station 300, so that the satellite station 300 adjusts the current communication policy after receiving the connection status through the satellite terminal. The connection state refers to an access state of the communication connection between the current ship end 100 and the satellite terminal; the communication strategy is an available state of the current ship end 100 for realizing the preset communication request through multiple communication modes, for example, in the embodiment of the present application, the available state of the preset communication request is mainly realized based on the FDMA communication network 400.
In a possible implementation example, the satellite relay gateway obtains a connection state between the satellite terminal of the ship end 100 and the satellite terminal of the satellite station 300 side through the satellite station control device, the satellite relay gateway issues an FDMA communication means access state of the ship to a soft switch server of a central machine room of the shore base end 200, and the soft switch server updates an available state of a communication method based on the FDMA communication network 400 of a corresponding ship user, wherein the available state indicates whether the corresponding ship user has the capability of making a communication call through the FDMA communication network.
Specifically, the satellite station control device of the satellite station 300 periodically releases the access state and the connection state of the satellite terminal in the station in a multicast manner, the satellite relay gateway monitors the connection state of the satellite terminal administered by the relay gateway by monitoring the multicast address to acquire the access state of the ship, the satellite relay gateway periodically releases the access state of the FDMA communication means of the ship to the soft switch server by releasing information, wherein the access state comprises the ship platform ID, the satellite terminal ID connected with the ship end, and the satellite relay gateway address and port reporting the state, and finally the soft switch server updates the available state of the communication method of the user with the FDMA communication means in the corresponding ship according to the priority information of the communication strategy.
In step S130, the ship terminal 100 performs communication connection with the shore base terminal 200 according to the adjusted communication policy and the preset communication request, and it should be noted that performing communication connection in step S130 means that the ship terminal 100 performs call connection with the shore base terminal 200 through a one-number based on the FDMA communication network 400, so that a ship user of the ship terminal 100 can call the shore base terminal 200 in a one-number manner. In practical applications, the ship terminal 100 can also make a call connection with another ship terminal 100 through a one-number, which is not described in detail in this application. The preset communication request is generated according to the first mapping identifier of the ship end and a preset initial communication request, the initial communication request is a call request initiated according to a communication number inside the ship, and the preset communication request is called to a shore base end according to a one-number of the ship end.
In some embodiments, the ship end 100 includes an access gateway and a ship internal communication system, where the access gateway is the access gateway shown in fig. 1, and the ship internal communication system is the ship internal communication system shown in fig. 1, and with reference to fig. 3, step S130 further includes the following steps:
s131, the internal communication system of the ship initiates an initial communication request and sends the initial communication request to an access gateway;
and S132, the access gateway changes the first communication request initial communication request into a preset communication request according to the second mapping relation, sends the preset communication request to the satellite terminal according to the adjusted priority information of the communication strategy, the first mapping relation and the third mapping relation, receives a communication response returned by the satellite terminal, executes secondary dialing according to the communication response and establishes communication connection with the shore base terminal.
In step S131, the ship internal communication system initiates an initial communication request and sends the initial communication request to the access gateway, and actually initiates a call connection from the captain of the ship end 100 shown in fig. 1 to the user at the shore base end 200 through an internal communication number, and the ship internal communication system forwards the initiated call connection to the access gateway.
In step S132, after receiving the initial communication request forwarded by the ship internal communication system, the access gateway changes the initial communication request into a preset communication request according to the obtained second mapping relationship, and sends the preset communication request to the satellite terminal by analyzing the availability and priority information of the communication policy of the current ship accessing the FDMA communication network 400 and the first mapping relationship and the third mapping relationship, and receives a communication response returned by the satellite terminal, and executes a second dialing according to the communication response, thereby establishing a communication connection with the shore base end 200. The access gateway may analyze priority information and availability of a communication method accessed by the current ship end 100, for example, the current ship end 100 only accesses the FDMA communication network, and the FDMA communication is the communication method that is the highest priority information among currently available communication methods, that is, communication means, and the access gateway may allocate an idle FXO port to the calling user in combination with the mapping relationship between the ship user and the satellite terminal port acquired in step S110, and send a preset communication request to the satellite terminal through the FXO port. The satellite terminal returns a communication response to the access gateway after receiving the preset communication request, and the access gateway executes secondary dialing after receiving the communication response, so that the ship terminal 100 and the shore base terminal 200 establish a communication request.
The secondary dialing refers to that the ship terminal 100 acquires a relay communication identifier of a port corresponding to a satellite terminal of the shore base end 200 and an initial communication identifier corresponding to the shore base end 200 according to a received preset communication request, where the relay communication identifier is a relay number corresponding to a port number, and the access gateway dials the relay communication identifier first and then dials the initial communication identifier corresponding to the shore base end 200, where the initial communication identifier is a call number of a user of the shore base end 200.
In the satellite station 300 and the shore base end 200, when receiving a call request of a satellite terminal to the shore base station, that is, a preset communication request of the ship end 100, the satellite relay gateway forwards the preset communication request to program control of the satellite station 300 according to locally configured routing information, that is, the program controlled switch routes the preset communication request to a user of the shore base end 200 according to a called number, that is, an initial communication identifier of the shore base end 200 and routing information configured by the program controlled switch, so that a communication connection, that is, a call, between the ship end 100 and the shore base end 200 is established.
