Embodiment
Utilize untimely, the halfway problem of keyword filtration short message in order to solve prior art, the invention provides a kind of method and device that short message is filtered fully, below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, does not limit the present invention.
The embodiment of the invention is the related signaling content that base station side is received and dispatched according to the gsm protocol short message, and to a kind of method that up short message filters fully, overall strategy is:
Base station side is after starting the short message filtering function, filtration treatment can be distinguished to the uplink service in all various situations in the zone of action in the base station, at first, at the signaling channel establishment stage signalling point that can distinguish up short message service is carried out type of service identification; Then, the up short message service flow process that termination picks out forbids that its content sends to BSC (Base Station Controller, base station controller); At last, the SDCCH of release busy (Separate Dedicated Control Channel, Separate Dedicated Control Channel) channel resource.
The embodiment of the invention can fast be filtered short message rapidly in certain time period and territorial scope fully for the space-time characteristics that illegal short message sends, and forbids its large tracts of land propagation.Filtering rule is simple, need not the user participates in, operator can be according to actual needs, starts the filtering short message function in certain hour section and territorial scope, just can be in the time range of setting filters fully during the transmission of all-pair point short message in to the jurisdiction district.The method was than short message filter method was faster in the past simultaneously, and the radio channel resource that takies also still less.
As shown in Figure 1, the embodiment of the invention relates to a kind of method that short message is filtered fully, comprising:
Step S101, the business request information that the base station side receiving terminal sends.
Step S102 judges whether the type of service of business request information is short message service, if so, then turns step S103; If not, then turn step S104.
Step S103 when the type of service in judging business request information is short message service, filters short message, that is, all filter the short message service that all receive the base station, and then realizes the fully filtration to point-to-point short message transmission.Filtration in the present embodiment refers to stop up short message service flow process in base station side, forbids content of short message is sent to BSC, and the SDCCH channel resource of last release busy.
Step S104 when the type of service in judging business request information is not short message service (i.e. the type of service of all except short message service), continues business request information is processed.That is, proceed to process according to the original operation flow of various types of traffic.
In addition, because the base station just just starts the complete filtering function of short message under specific circumstances, and under normal circumstances, the base station also needs to finish the sending function of normal short message, therefore, the base station need to have short message and send complete filtering function switch, is convenient to manually open in certain hour section and territorial scope or close the short message filtering function.In the time need to realizing the function of filtration to all short messages in certain hour section and the territorial scope, then should at first start the short message filtering function, that is: open short message and send complete filtering function switch.Short message sends the needs that filter fully in certain time period and the region in order to satisfy flexibly, the setting that short message sends complete filtering function switch should comprise action time and sphere of action two aspects: action time, default setting was to open namely to work, and also can adopt the mode of presetting section action time; Sphere of action is take the base station cell scope as the preferred plan setting, because like this can be to carry out fully filtration in the zone close to geographic Minimum Area as unit, to reduce the impact on other normal short message services in zone.
The below is with three specific embodiments, introduces in detail under the different situations filtering process to short message:
Because when up short message sent, the state of MS (Mobile Station, travelling carriage) may be Idle state, also may be conversation state, in addition, resend the situation of short message after also existing the MS position to upgrade, therefore, specific implementation comprises following three class cases:
Case one:
Fig. 2 filters the short message service process figure that Idle state terminal (travelling carriage) sends fully among the present invention.According to the signaling process that the terminal that is in Idle state (for example mobile phone) sends SMS message, filter the short message that mobile phone sends under the Idle state, according to overall strategy, implementation is as follows:
Step S201, MS asks message for instructions to BTS (Base Transceiver Station, base transceiver station) transmitting channel;
Step S202, BTS asks channel for instructions message and is transmitted to BSC;
Step S203, BSC activates message to the BTS transmitting channel;
Step S204, BTS activates response message to the BSC transmitting channel;
Step S205, BSC sends immediate assignment message to MS;
Step S206, MS sends business request information to BTS, and specifying type of service in first up SABM (asynchronous balance mode being set, Set Asynchronous Balanced Mode) frame is short message, be CM SERVICE TYPE=SMS, and SAPI=0;
Step S207, BTS sends response (UA) to MS;
Step S208, the base station is to (the 3rd layer of the L3 of first up SABM frame of the signaling channel establishment stage received, Layer 3) message judges, when CM SERVICE TYPE (CM type of service) is SMS (Short Message Service, short message service), and SAPI (Service Access Point Identifier symbol, Service Access Point Identifier)=0 o'clock, base station side will not report the EST IND of this short message service (to set up indication to BSC, Establish Indication) signaling, initiatively send relevant signaling request to MS and BSC respectively simultaneously and discharge the SDCCH channel, and then stop the Idle state mobile phone to send SMS message.
Step S209, BSC responds deexcitation message to BTS.
Case two:
Fig. 3 is the flow chart that mobile phone sends when in the embodiment of the invention position being upgraded short message filters fully.When mobile phone carries out the position when upgrading, tend to and will send before this unsuccessfully or content of short message to be sent resends, filter short message in this case, according to overall strategy, implementation is as follows:
Step S301, MS asks message for instructions to the BTS transmitting channel;
Step S302, BTS asks channel for instructions message and is transmitted to BSC;
Step S303, BSC activates message to the BTS transmitting channel;
Step S304, BTS activates response message to the BSC transmitting channel;
Step S305, BSC sends immediate assignment message to MS;
Step S306, MS sends first up SABM frame to BTS, specifies CM SERVICE TYPE=Location Updating Request in first up SABM frame, and SAPI=0;
Step S307, BTS send to BSC and set up indication; Comprise CM SERVICE TYPE=Location Updating Request in the foundation indication, and SAPI=0;
Step S308, BTS sends response (UA) to MS;
Step S309, MS sends second up SABM frame to BTS, and in second up SABM, indication L3 message is empty (message-length is 0), and SAPI=3;
Step S310, the base station is judged the L3 message of second up SABM frame of the signaling channel establishment stage received, if L3 message is empty, and during SAPI=3, base station side will not report the EST IND of this short message service to BSC;
Step S321, BTS initiatively send relevant signaling to MS with BSC respectively simultaneously, require to discharge the SDCCH channel, and then mobile phone sends SMS message when stoping the position to be upgraded.
Step S312, BSC responds deexcitation message to BTS.
Case two belongs to a kind of special circumstances that the Idle state mobile phone sends SMS message, so case one and case two have consisted of the complete scheme of Idle state short message filtering together.
Case three:
Fig. 4 filters under the conversation state mobile phone flow chart that sends SMS message fully in the embodiment of the invention.According to the signaling process that mobile phone under the normal talking attitude sends SMS message, filter the short message that mobile phone sends under the conversation state, according to overall strategy, implementation is as follows:
Step S401, MS sends measurement report to BSC;
Step S402, MS sends the data indication to BTS, points out that type of service is short message service, that is: CM SERVICE REQUEST=SMS, SAPI=3; DATA IND (the Data Indcation of base station to receiving under the conversation state, the data indication) the L3 content of signaling is resolved, then according to judging its type of service about MESSAGE TYPE (type of message) unit in the L3 message of DATA IND and CM SERVICE TYPE cell value in 3GPP TS 24008 agreements, when if its value sign is respectively CM SERVICE REQUEST (CM service request) and SMS, then be judged to be short message service, base station side will not report the DATA IND signaling of this short message service to BSC, and then stops the short message that mobile phone sends under the conversation state;
Step S403, MS sends measurement report to BSC;
Step S404, MS continue to send measurement report to BSC; Showing that MS appoints so is in the talking state.
In addition, as shown in Figure 5, the embodiment of the invention also relates to a kind of device that short message is filtered fully of realizing said method, comprising:
Business request information receiver module 501 is used for the business request information that sends at the base station side receiving terminal;
