Embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.
Fig. 1 is the method flow diagram of short message service center's filter message of the present embodiment.
S101 receives the short message from External Short Message Entity ESME (as mobile phone terminal);
S102 searches the default filtering policy corresponding with this control information according to the control information in message header;
In message header, the corresponding relation of control information and filtering policy can be arranged by short message service center, also can send to short message service center by other network entities; Filtering policy can comprise: increase charging identifier, additional charges; Be left intact, transparent transmission; Delete message header; Refuse this message;
Because existing short message service center can make white list according to the credit rating of mobile phone terminal, (white list refers to the mobile phone terminal that can trust completely to blacklist, blacklist refers to the mobile phone terminal that can not trust completely), for improving the treatment effeciency of short message service center to short message, short message service center, after the short message receiving from white list, can directly pass through recipient by this short message; After the short message receiving from blacklist, can directly refuse to process this short message, return to transmission failed message to transmit leg; Receiving after the short message sending from the number outside white list or blacklist, then searching the default filtering policy corresponding with this control information according to the control information in the message header of reception short message;
Or short message service center increases gray list function on the basis of existing black, white list again, by by customer complaint but the number of failing to check and verify is listed gray list in; Short message service center only carries out filtering policy judgement to the short message from gray list;
Control information in above-mentioned message header can, for imformosome mark (IEI), because IEI is with the different imformosome content of digitized representation, as IEI=0, represent that message body content is long message; IEI=20, represents RFC5322E-Mail Header; In the time formulating filtering policy corresponding to IEI, can be by IEI=0 time, corresponding filtering policy be formulated as transparent transmission short message, and during by IEI=20, corresponding filtering policy is formulated as refusal short message;
S103 processes the short message receiving according to filtering policy;
If filtering policy, for refusal short message, stops the processing to described short message; If filtering policy is non-refusal short message, according to described filtering policy, described short message is processed to rear continuation and search the default filtering policy corresponding with this next one control information according to the next control information in message header; As, in message header, carry two IEI, be respectively IEI=0 and IEI=20; In the time that short message service center gets first IEI=0, know that the filtering policy corresponding with this control information is transparent transmission short message, short message service center continues to obtain IEI=20, knows that the filtering policy corresponding with this control information is for refusal short message, and short message service center stops the processing to receiving short message.
Fig. 2 is the composition module map of the short message service center for filter message of the present embodiment.
This short message service center comprises filtering policy determination module and short message filtering module, wherein,
Filtering policy determination module, for receiving after short message, searches the default filtering policy corresponding with this control information according to the control information in its message header, and this filtering policy is sent to short message filtering module;
In message header, the corresponding relation of control information and filtering policy can be arranged by short message service center, also can send to short message service center by other network entities; Filtering policy can comprise: increase charging identifier, additional charges; Be left intact, transparent transmission; Delete message header; Refuse this message;
This filtering policy determination module, can search the default filtering policy corresponding with this IEI according to the imformosome mark (IEI) in its message header; Because IEI is with the different imformosome content of digitized representation, as IEI=0, represent that message body content is long message; IEI=20, represents RFC5322E-Mail Header; In the time formulating filtering policy corresponding to IEI, can be by IEI=0 time, corresponding filtering policy be formulated as transparent transmission short message, and during by IEI=20, corresponding filtering policy is formulated as refusal short message;
This filtering policy determination module, also for receiving after short message, judge whether to determine the degree of belief of short message transmit leg, if the degree of belief of this short message transmit leg can not determine, then search the default filtering policy corresponding with this control information according to the control information in message header;
Short message filtering module, for processing the short message receiving according to filtering policy;
Whether this short message filtering module, be refusal short message for the filtering policy that judges reception, if the filtering policy receiving is refusal short message, stops the processing to described reception short message; If the filtering policy receiving is not refusal short message, obtains the filtering policy corresponding with next control information message header from described filtering policy determination module, and continue to process receiving short message according to this filtering policy; As, in message header, carry two IEI, be respectively IEI=0 and IEI=20; In the time that short message filtering module gets filtering policy that IEI=0 is corresponding and is transparent transmission short message, continue to obtain from filtering policy determination module the filtering policy that IEI=20 is corresponding, the filtering policy corresponding due to IEI=20 is refusal short message, and short message filtering module stops the processing to receiving short message.
One of ordinary skill in the art will appreciate that all or part of step in said method can carry out instruction related hardware by program and complete, described program can be stored in computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of above-described embodiment also can realize with one or more integrated circuits, and correspondingly, the each module/unit in above-described embodiment can adopt the form of hardware to realize, and also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
It should be noted that; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
