Step 43, when the mobile subscriber sends upstream message to gateway device, gateway device at first the content of upstream message is carried out code conversion and alphabet size is write conversion, full-shape/half-angle conversion, the processing such as deletion in the space, front and back of message content, the format conversion that makes upstream message is to be the consistent form of upstream operation instruction of SP configuration with gateway device, and according to the upstream operation instruction that comprises in the upstream message behind the format transformation, whether there is this upstream operation instruction that comprises in the upstream message in the question blank 2, at Query Result when being, execution in step 44, otherwise, execution in step 45;
Step 44, upstream message is transmitted to upstream operation instructs corresponding SP, such as, the mobile subscriber edits upstream operation instruction (being short message content) tqyb to 10655789, then according to table 2, can inquire this upstream message corresponding to SP1, thereby gateway device is transmitted to the SP that is designated SP1 with this upstream message, flow process finishes;
Step 45, cancellation are to the forwarding of this upstream message, and flow process finishes.
Need to prove, in above-mentioned steps 43, do not have the unified format requirement if the alphabet size in the upstream message content that gateway device is sent the mobile subscriber is write to wait, then can upstream message be changed yet, instruct but can directly from upstream message, obtain upstream operation.
Embodiment 2:
Please refer to Fig. 5, it is 3 different SP (SP1 that the such scheme that this Fig. 5 provides for the embodiment of the invention is applied to, SP2, SP3) distribute Number for access respectively, service code, behind the SPID, the Number for access that later use distributes, service code, SPID etc., realize schematic flow sheet that downstream message is sent, because for SP distributes Number for access, service code, the process of SPID etc. and be the process of SP configuration routing iinformation and the step 41 among the embodiment 1,42 unanimities, therefore repeat no more, following steps mainly illustrate the process that downstream message is carried out authentication and sends:
Step 51, the gateway device in the short-message system will send to mobile subscriber's the downstream message from SP, obtain service code and the Number for access of the SP of this downstream message of transmission;
Step 52, the service code that judge to obtain and the corresponding relation of Number for access whether with corresponding relation as shown in table 2 in the corresponding relation of corresponding business code and Number for access consistent, when judged result for not the time, execution in step 57, otherwise, execution in step 53, such as, SP1 uses Number for access 10655789, service code sxiuh to send downstream message, then according to table 2 as can be known, Number for access 10655789 is consistent with corresponding relation and the corresponding relation in the table 2 of service code sxiuh, then can execution in step 53;
Step 53, from the SP that sends this downstream message when the login short-message system the used log-on message, obtain first SPID of the SP of this downstream message of transmission, and according to the service code that obtains, from corresponding relation as shown in table 2, determine and the corresponding SPID of service code that obtains, such as, at using Number for access 10655789, service code sxiuh sends the SP1 of downstream message, from log-on message, first SPID that can obtain this SP1 is 300123, and according to the service code sxiuh in the downstream message, can find the SPID corresponding with service code sxiuh from table 2 is 300124;
Step 54, relatively whether first SPID is consistent with the SPID of determining, is when denying at comparative result, execution in step 57, otherwise, execution in step 55, such as, because first SPID of the SP1 that determines in the above-mentioned steps 53 is 300123, and the SPID of the SP1 that determines according to table 2 is 300124, this shows that SP1 is utilizing the SPID that does not belong to self to send downstream message, thereby the authentication that draws this downstream message gets nowhere, and transfers execution in step 57 to;
Step 55, further according to sign and the table 2 of the SP of this downstream message of transmission that comprises in the downstream message, whether the SP that judge to send this downstream message has is used the service code that comprises in this downstream message and the authority of Number for access, because before execution in step 55, corresponding relation and the stored relation of having determined the service code that obtains and Number for access in step 52 are consistent, therefore, in this step 55, whether corresponding relation and the corresponding relation in the table 2 that can only determine to send the service code that comprises in sign and the downstream message of SP of this downstream message be consistent, and determining that the result is the corresponding relation of the service code that comprises in the sign of the SP that sends this downstream message and the downstream message and the corresponding relation in the table 2 when consistent, judge whether this SP that sends this downstream message has and use the service code that comprises in this downstream message and the authority of Number for access, then execution in step 56, otherwise, transfer execution in step 57 to;
Step 56, the recipient's sign according to comprising in the downstream message sends to the corresponding mobile user with this downstream message, and flow process finishes;
Step 57, refusal sends this downstream message, and flow process finishes.
Sum up the foregoing description 2, only in the employed Number for access of SP that sends downstream message, service code, the sign of SPID and SP and corresponding relation as shown in table 2 are corresponding fully when consistent, just determine downstream message authentication success to sending, otherwise, if sign and the Number for access corresponding relation of the sign of the SP of appearance transmission downstream message and the corresponding relation of Number for access and the SP in the table 2 are inconsistent, or the corresponding relation of the service code of the corresponding relation of the service code of the SP of transmission downstream message and SPID and the SP in the table 2 and SPID is inconsistent, illustrate that all the SP of current transmission downstream message might usurp the Number for access of other SP, service code and/or SPID, thus refusal sends this downstream message.This downstream message sending method that the embodiment of the invention provides is utilized a plurality of information corresponding relation of (comprising Number for access, service code, SPID, SP sign), downstream message is carried out authentication, and only the downstream message of authentication success is sent, thereby can prevent that incredible SP from usurping information such as the Number for access of other credible SP, service code and sending downstream message.
