and receiving a position updating request sent by the first application server, and updating the terminal routing information corresponding to the first number.
After the registration process is completed and the account is opened successfully, the first terminal needs to execute a login process before initiating a terminal service request at sea.
And sending a login request to the first satellite unit by the first terminal, wherein the login request at least comprises a first number and login information.
After receiving the login request, the first satellite unit firstly judges whether login information in the received login request meets preset login conditions. And if so, replying a login success message to the first terminal.
The first terminal needs to update the terminal position information of the first terminal when receiving the login success message, and sends a position updating request to the first application server, wherein the position updating request at least comprises the terminal position information of the first terminal. And the first application server forwards the Location updating request to the first satellite broadband unit, and the first satellite broadband unit sends the Location updating request to a Home Location Register (HLR) of the large network side to update the terminal routing information corresponding to the first number.
In the embodiment of the invention, after the first terminal finishes registration through the first application server and the first satellite broadband unit, the first terminal initiates a login process to the first satellite broadband unit and updates the position information of the terminal, then the first terminal initiates a terminal service request comprising a first number and a second number, and then the first application server and the first satellite broadband unit respectively send the broadband service request to the second terminal through the large-network side equipment according to the pre-stored corresponding relation between the first number and the second number and the first SIP identification and the second SIP identification, so that the cost of marine satellite communication can be greatly reduced, and the marine communication of fishermen is more convenient and effective.
Based on the above embodiment, further, the method further includes:
if the login information does not meet the login condition, a login failure message is sent to the first application server, so that the first application server sends the login failure message to the first terminal, and the first terminal sends a verification code request to the first application server;
receiving a verification code request sent by the first terminal, and sending the obtained verification code to the first terminal so that the first terminal sends a new login request containing the verification code to the first application server;
and receiving the new login request sent by the first application server, after judging that the verification code is correct, reallocating a new first SIP identifier to the first number, updating the mapping relation table, and sending the new first SIP identifier to the first application server so that the first application server sends a login success message to the first terminal.
After the first terminal sends a login request to a first satellite broadband unit, if login information in the first satellite broadband unit does not meet the login condition, a login failure message is sent to the first application server.
Further, the login conditions include:

and the first number in the login information is in a normal state in the HLR.
The login conditions may be specifically set according to actual needs, and in the embodiment of the present invention, only one example is given, and whether the login conditions are met is determined by checking the content included in the login information in the login request:
checking whether the position of the first terminal contained in the login information meets a preset area or not to realize a service use area limiting function, if the position of the first terminal in the login information meets the preset area, for example, in a maritime area, judging that the login condition is met, otherwise, judging that the login condition is not met;
checking whether a first terminal sending the login information uses the first number for the first time to execute a login process, if so, judging that the login condition is met, otherwise, judging that the login condition is not met;
checking whether the first number in the login information logs in other terminals or not, if not, judging that the login condition is met, otherwise, not, judging that the same first number cannot log in different terminals, and if the first number logs in a new terminal, forcibly offline the other terminals;
checking whether the IMSI corresponding to the first number in the login information changes or not, if not, judging that the login condition is met, otherwise, judging that the card change phenomenon of the first number occurs, so that the IMSI corresponding to the first number changes;
and checking whether the state of the first number in the HLR is normal or not, if so, judging that the login condition is met, otherwise, judging that the login condition is not met, and if not, judging that the abnormal state is more, for example, the first number can be reported to be lost by the first user.
In the process of checking the login information, the preset login condition can be determined to be met only if all the login conditions are met, and at this time, the first satellite broadband unit sends a login success message to the first terminal. If any login condition is not met, the login is judged to be failed, the first satellite broadband unit sends a login failure message to the first terminal, and the login failure message can also comprise the reason of failure and information requiring short message authentication.
And the first terminal sends a verification code request to the first satellite broadband unit according to the login failure message, so that the first satellite broadband unit obtains a corresponding verification code and sends the verification code back to the first terminal.
And the first terminal sends a new login request containing the verification code to the first satellite broadband unit. And if the first satellite broadband unit judges that the first number in the connected new login request is correctly corresponding to the verification code, the first satellite broadband unit considers that the verification is successful, and meanwhile, a new first SIP identifier is redistributed to the first number, and the part corresponding to the first number in the mapping relation table is updated. And sending the new first SIP identifier to the first application server so that the first application server updates the first SIP identifier associated with the first number and sends a login success message to the first terminal.
In the embodiment of the invention, after the first terminal finishes registration through the first application server and the first satellite broadband unit, the first terminal initiates a login process to the first satellite broadband unit, if login fails, a new first SIP identification is distributed to the first number, the first terminal initiates a terminal service request comprising the first number and the second number, and then the first application server and the first satellite broadband unit respectively send the broadband service request to the second terminal through the large-network side equipment according to the pre-stored corresponding relation between the first number and the second number and between the first SIP identification and the second SIP identification, so that the cost of marine satellite communication can be greatly reduced, and fishermen can more conveniently and effectively communicate at sea.
