Description
Technical field
The invention belongs to the communications field, particularly telecom business support system, signaling monitoring system technical field.
Background technology
In the GSM network; Because a variety of causes such as " frequent position is upgraded ", " weak covering ", " interference ", " inadequate resource " can cause paging failure, for the higher zone of paging failure rate; We are referred to as the paging failure sub-district, also are called sub-district, paging black hole.Paging failure is that MSC is after sending paging PAGING message; Do not receive PAGRES message in the timer; MSC then can issue PAGING message once more, issues when all not receiving PAGRES message the then failure of radio call this time at the beep-page message several times of the paging policy regulation of exchange.
In existing technology, can only come discovery paging failure sub-district at random through drive test at present.Drive test is a kind of mode of sampling analysis, can only analyze the zone of drive test terminal movement locus process, and is then powerless to other zones.Yet have problems when adopting the drive test mode to judge paging failure, if for example in the time that the drive test terminal is passed through, the paging failure phenomenon does not take place in wireless network, and drive test can't analyze the phenomenon of this paging failure.
Summary of the invention
In order to solve the prior art problem, the present invention carries out complete analysis through the no-response paging signaling of signaling monitoring system and the fuzzy matching of user behavior to all sub-districts in the monitoring range, searches the paging failure sub-district.Particularly, the present invention proposes a kind of method of analyzing the paging failure sub-district, this method comprises:
S1. filter out paging failure signaling record;
S2. from said paging failure signaling record, extract the TMSI or the IMSI information of call terminal;
S3. according to TMSI that is extracted or IMSI information, search current paging failure constantly before and/or N minute afterwards in other signaling records of said call terminal;
S4. extracting position district LAI information and sub-district CI information from said other signalings record, and preserve;
S5. LAI and the CI information extracted are added up, LAI that wherein statistics number is maximum and the pairing sub-district of CI are the paging failure sub-district.
In addition, the present invention also proposes a kind of device through subscriber signaling behavior fuzzy analysis paging failure sub-district, and wherein this device comprises:
Filtering module is used to filter out paging failure signaling record;

Embodiment
To be elaborated according to the accompanying drawing specific embodiments of the invention below.
Fig. 1 is a radio call process sketch map in gsm mobile communication system.The process of radio call, promptly MSC searches out the communication process of mobile subscriber MS through paging, and only after finding the mobile subscriber, MSC just can carry out next step call proceeding work.
This process specifically comprises: when MSC obtains MS present located Location Area Identity (LAI) from VLR after, will send beep-page message (PAGING) to all BSC of this lane place.After BSC received beep-page message, paging command message (PAGINGCOMMAND) was sent in all sub-districts that under this BSC, belong to this lane place.After paging command is received in the base station, will on the paging subchannel of this IMSI place of wireless channel paging group, send paging request message (PAGING REQUEST), carry paged user's IMSI or TMSI in this message.MS distributes standalone dedicated control channel (SDCCH) through RACH (RACH) request after receiving paging request message.BSC is then confirming base station activation behind the required SDCCH channel, gives travelling carriage through immediate assignment message (IMASS) with this SDCCH channel assignment at access permission channel (AGCH).Travelling carriage then uses this SDCCH channel to send page-response message (PAGRESPONSE).BSC gives MSC with the PAGRES forwards, accomplishes once successful radio call.According to the existing network setting; If MSC is after sending PAGING message, do not receive PAGRES message in n second (n depends on switch Timer configuration), the MSC PAGING message of then can redispatching one time; If n does not still receive PAGRES message in second (n depends on switch Timer configuration); The then failure of radio call this time, simultaneously, MSC will send called subscriber's recorded announcement (like " user that you dialed temporarily can't connect ") to the calling subscriber.
Shown in Fig. 2 and 3, only comprise Location Area Identification (LAI) in the beep-page message (PAGING).At no-response paging is under the situation of paging failure, and we can't be directly accurately orient what paging failure took place through beep-page message (PAGING) is which sub-district (Cell).
In order to confirm the subdistrict position of paging failure, the present invention will be starting point with the situation of no-response paging, through the subscriber signaling behavior fuzzy analyze the paging failure sub-district.
Referring to Fig. 4; Paging failure takes place in certain sub-district in a user; We suppose that (N value value is crossed conference and reduced paging failure business and the probability of other business in same sub-district, causes final statistics accuracy to descend, according to feasibility analysis in forward or backward N minute for it; The optimum value of N is got between 5 minutes to 10 minutes; For example 5 minutes or 6 minutes or 10 minutes), once carried out normal other signaling behaviors in this sub-district, these behaviors comprise exhalation or receive calls, send or receive note, position renewal etc.In these signaling procedures, carry lane place (LAI) and sub-district (CI) that business conduct takes place, for example in position updating process,, can obtain LAI and CI information through Location Updating Request message; For example,, can obtain LAI and CI information through Paging Response message receiving calls or receiving in the note process; For example in calling or send the note process,, can obtain LAI and CI information through Assignment Complete message.
In the beep-page message (PAGING) of paging failure process; We can get access to the IMSI/TMSI number; When carrying out fuzzy analysis, we are filtercondition with IMSI/TMSI, and signaling procedure is upgraded in calling, note, the position inquired about forward or backward N minute; If can find corresponding signaling procedure, then the LAC in this process, CI preserved as Query Result.
Repeatedly statistics through certain hour sorts to the LAC in the statistics, CI, the more pairing sub-district of LAC, CI of this subscriber signaling behavior number of times took place in the unit interval be confirmed as the paging failure sub-district.
Referring to Fig. 5, the method for the analysis paging failure sub-district that the present invention proposes specifically may further comprise the steps:
S1. filter out paging failure signaling record;
S2. from said paging failure signaling record, extract the TMSI or the IMSI information of call terminal;
S3. according to TMSI that is extracted or IMSI information, search current paging failure constantly before and/or N minute afterwards in other signaling records of said call terminal;
S4. extracting position district LAI information and sub-district CI information from said other signalings record, and preserve;
S5. LAI and the CI information extracted are added up, LAI that wherein statistics number is maximum and the pairing sub-district of CI are the paging failure sub-district.
Wherein, search among the step S3 current paging failure constantly before and/or N minute afterwards in other signalings records be specially only search current paging failure constantly before other signaling records in N minute.
