Embodiment
Point-to-point short message service is made up of two kinds of basic services: SM MO (point-to-point mobile originated short message), SM MT (point-to-point travelling carriage termination short message).SM MO indicates from travelling carriage (MS) to Short Message Service Center (SMSC, Short Message Serve Center) short message of submitting, and provide information about delivery report or error reporting by a kind of specific mechanism, SM MO flow process as shown in Figure 2; The indicate short message that issues to travelling carriage (MS) from Short Message Service Center (SMSC) of SM MT, and provide about issuing the information of report or error reporting, as shown in Figure 2 by a kind of specific mechanism.Above-mentioned two kinds of message all are transparent message (forwarding is responsible in the base station, not any explanation or change in addition) for the base station.
Function is summarized
The present invention, decodes to content of short message when the transparent transmission short message of base station according to the agreement that short message sends and receives, and carries out short message filtering by the base station according to decode content and filtering rule; If do not meet filtering rule, the short message of transmission will be rejected and send to Short Message Service Center.
Embodiment one
The S101 base station judges whether the signaling that receives is short message, if short message continues S102
S102 decodes to short message the base station, and according to filtering rule short message is filtered.
The S101 base station judges whether the signaling that receives is that short message is specially, as shown in Figure 3: whether DATA IND message of the signaling receive is judged in the base station, judging further then in this way whether its SAPI is 3 (short message message types), is not that 3 continuation are waited for if not DATA IND message and its SAPI.If SAPI is 3 DATA IND message, judge further then whether its message that comprises is CP-DATA message (short message service process), be that CP-DATA message is then further distinguished RP-MO-DATA (up) and RP-MT-DATA (descending) message, to up short message decoding and filtration.
Filtering rule among the S102 can have various ways, one filters according to the source address and the destination address of short message, its two startup restricted number at content of short message startup keyword shielding or identical content of short message, its three all right enabling time section restriction realizes the filtration to short message.Simultaneously junk short message is started the warning of junk short message source automatically, promptly system is according to the source address of short message, and the information that gives a warning is automatically given the terminal that sends junk short message, and need not user's participation.
Particularly, decode to short message in the base station, solves source address and destination address, content of short message and transmitting time, filters according to these information.Filtering rule comprises concretely: 1. based on the filtration of address (address according to message originator judges whether to filter, i.e. blacklist form, blacklist can operator be provided with, and also comprises the blacklist that other 3 kinds of modes generate automatically.Removed after piping off 3 days), 2. the content-based filter type (keyword in the text message, as " gun ", " fine and confiscation automobile " or the like), 3. based on the control of message quantity forwarded (restricted number that same source address sends in the unit interval), 4. based on the filtration of time period (operator sets needs filtering time period, as point～5 point at night 0).
S102 short message filtering processing method and flow process, as shown in Figure 4.After the short message decoding, deposit source address respectively in, destination address, content of short message, whether transmitting time field, these information carry out filtering as the input of message screening through the coupling judgement of filtering rule.
At filtering rule, can be set at blacklist and have right of veto by one vote, in order to reduce the probability of erroneous judgement, its excess-three factor needs to judge simultaneously.If then sending SMS message, the message of filtering transmits failure reporting and/or source warning, if judgement is not need the message of filtering then the transparent transmission transmission.Message for filtering is stored, and the storage time limit can be set at 24 hours, as the foundation of later message screening.Blacklist is also according to time limit and newfound rubbish source address automatically and dynamically updating.Simultaneously, for also storing by the short message that filters, the purpose of storage is to do restricted number, if can not filter by other filtering rules, but in order to prevent that the user from sending the information of identical content in the short time, then with this junk short message that also is considered as, so even without filtering out, also need storage, be accumulated to thresholding in the unit interval and then do to filter and abandon.
Embodiment two
Embodiment one is at up signaling, and promptly the short message of Fa Songing filters.In order to make the junk short message filter effect better, make the user obtain better enjoyment, simultaneously, can carry out the filtration of junk short message at base station down, do not send to user mobile phone.
The filtration of base station down signaling is the same with the filter method of up signaling.At first, the base station judges whether the signaling that receives is short message.Be specially, whether DATAIND message of the signaling receive is judged in the base station, judges further then in this way whether its SAPI is 3 (short message message types), is not 3 if not DATA IND message and its SAPI and continues to wait for.If SAPI is 3 DATA IND message, judge further then whether its message that comprises is CP-DATA message, be that CP-DATA message then further judges whether the message into RP-MT-DATA (descending).Secondly, decoding to short message in the base station, and according to filtering rule short message is filtered.The setting of filtering rule can be identical with up short message filtering, also can set in addition.
Embodiment three
Present embodiment provides a kind of base station of filtering junk short message, on the basis of existing base station, has increased the short message filtering function.Particularly, comprise following several module:
Short message receives judging unit, is used to judge whether the signaling of reception is short message; Further, judge that the short message that receives is up signaling or downlink signaling.Short message reception unit can be set at finger up short message is carried out filtration treatment; Perhaps up short message and descending short message are all carried out filtration treatment.
The short message decoding unit is used for the decoding of the short message that receives, and further, the combined filtering rule can be specially source address, destination address, content of short message, part or all in the transmitting time field to the decoding of short message.
The short message filtering unit is used for filtering according to the filtering rule of setting.
The short message transmitting element is used for whether decision sends SMS message according to filter result.Further, to not by the short message of filtration, then send SMS message and transmit failure reporting and source warning.
Further, in conjunction with actual conditions, the short message filtering functional module can be accomplished on the BBU (BASEBAND UNIT, Base Band Unit).Fig. 5 is short message filtering functional module (FSMS, Filter of SMS) position view in network element, base band and radio frequency unit are made in the module usually in the traditional base station, radio-frequency module is because problems such as heat radiation can't be accomplished very high integrated level, and the disposal ability of base band has obtained the lifting of advancing by leaps and bounds.Base band has obtained very big integrated level.A baseband pool disposal ability is equivalent to tens websites in traditional base station.The short-and-medium message screening function module of the present invention just is in the BBU unit, can handle the junk short message information in a sheet of zone, a plurality of sub-district simultaneously.
