Based on previous embodiment, the embodiment of the present invention provides a kind of analysis method that E-RAB discharges extremely, this method application In calculating equipment, the function that this method is realized can be realized by calculating the processor caller code in equipment, when Right program code can be stored in computer storage medium, it is seen then that the calculating equipment includes at least pocessor and storage media. In the specific application process, calculating equipment can be personal computer, server, industrial personal computer etc. and set with the electronics of computing capability It is standby.

Fig. 2 is the flow diagram for the analysis method that two E-RAB of the embodiment of the present invention discharges extremely, as shown in Fig. 2, the E- The analysis method that RAB discharges extremely includes:

Step 201, the original signaling of each interface in long term evolution (LTE) network in unit area is obtained；

Here, the unit area can refer to macrocell (cell).

Here, in the LTE network each interface include: LTE network main equipment Uu, X2 interface and S1-MME, S11, S10, S6a, S5/8 interface.During specific implementation, original signaling is obtained from signal collecting and resolver, wherein Signal collecting and resolver form each original signaling for being responsible for each interface signaling of acquisition LTE network and parsing.Wherein acquire Interface be related to main equipment software collection Uu, the X2 interface of LTE network, and by hardware acquire S1-MME, S11, S10, The interfaces such as S6a, S5/8.

Step 202, the critical event index that E-RAB discharges extremely is formed according to the original signaling；

Here, the critical event index and index classification (retentivity Retainability) of the above-mentioned table 1 into table 26 It is closely related.Critical event index (refering to table 1 to table 26) include: switch in E-RAB number, every QCI switches in E-RAB number, MME Initiate the E-RAB number of release, normal MME initiates the E-RAB number of release, the E-RAB number of eNB request release, the base station for dividing QCI Request the E-RAB number of release, the E-RAB number of normal base station requests release, the E- for dividing the normal base station requests of QCI to discharge RAB number, divides the E-RAB number, the initial context that cut out failure of QCI to be successfully established number, base station at the E-RAB number for cutting out failure Request free context number, normal base station requests free context number, wireless drop rate (cell-level), wireless drop rate, E- Drop rate that RAB is wireless (cell-level), E-RAB is wireless drop rate, E-RAB is wireless drop rate (QCI=1-9) (cell-level), E-RAB Wireless drop rate (QCI=1-9), mobile management entity cause E-RAB drop rate (cell-level), mobile management entity to lead to E- RAB drop rate, RRC connection establish request number of times, RRC connection reconstruction number of success (non-source cell), RRC connection reconstruction ratio With the such as RRC connection reconstruction failure rate

Wherein, the meaning of retentivity are as follows: carrying keeps the unbroken performance of connection status, for example, actively sending out for base station The E-RAB process risen, retentivity refer to the wireless drop rate of E-RAB；For mobile management entity actively initiate E-RAB process, Retentivity refers to E-RAB drop rate caused by mobile management entity (MME), and for switching out E-RAB release process, retentivity is Refer to RRC connection reconstruction ratio.

Based on this, the critical event index in step 202 may include RRC connection reconstruction ratio and E-RAB drop rate, Described in E-RAB drop rate include the wireless drop rate of E-RAB and the E-RAB drop rate as caused by mobile management entity, wherein institute Stating the wireless drop rate of E-RAB is the E-RAB drop rate that base station is actively initiated, and E-RAB caused by the mobile management entity goes offline Rate is the E-RAB drop rate that mobile management entity is actively initiated.

Here, it to switch in E-RAB number as critical event index, to illustrate step 202, is formed according to the original signaling The process for the critical event index that E-RAB discharges extremely switches in the definition of E-RAB number this index to count small referring to table 1 Area switches in E-RAB number, then forming the process for switching in E-RAB number according to the original signaling are as follows: obtain eNB and receive The RRC connection reconfiguration that UE is sent sets completion (RRC Connection Reconfiguration Complete) message, and discovery should RRC connection reconfiguration, which is set, completes message instruction UE cell when switching in, and counts the RRC connection reconfiguration and sets and completes the corresponding E- of message RAB number, including the switching between system (referring to 3GPP TS 23.401, TS 36.331 and TS 36.413)；To be cut Change to this critical event index of E-RAB number.

Step 72, it after leading to E-RAB drop rate high cell according to step 71 discovery mobile management entity, further unites Counting the cell mobile management entity causes E-RAB to go offline reason:

Mobile management entity is sent in E-RAB release command (E-RAB Release Command) message or UE to base station Request message is hereafter discharged, and does not receive the release request from base station before, it is a containing the E-RAB for requiring release in message Number, the corresponding sub-measure item of each reason.Wherein, the reason of abnormal release is not normal release cause, wherein normal release Reason include: include: normal release (Normal Release), separation (Detach), the inactive (User of user Inactivity), CS standby triggering (CS fallback triggered), terminal service unavailable (UE Not for PS Available For PS Service), RAT redirect (Inter-RAT redirection), redirect 1xRTT (Redirection towards 1xRTT).I.e. in each release message, release cause corresponding to each E-RAB is distinguished Add up the number of each reason.

Step 73, the cell for causing E-RAB drop rate high mobile management entity carries out a point reason according to step 72 Statistics.

In addition, also whether can have the message for causing mobile management entity to issue release further combined with interfaces such as S11, next pair Problem cells further position the reason that goes offline.Likewise, going offline for each exception of each terminal of each cell, also can Backtracking inquires the detailed content of the signaling process that this time goes offline and every signaling, such as information element (Information Element, IE) field etc..

Step 74: if according to step 73 as a result, mobile management entity actively initiate E-RAB discharge, can be according to step It is what concrete reason, solution that rapid 73 result, which is checked, are as follows: it is recommended that searching in signaling as according to indicating in this method The reason of IE field value, to questions and prospect carry out Primary Location, and then again particular problem make a concrete analysis of.If release cause is release Mobile management entity caused by balance (load balance) etc. initiates the E-RAB release of the terminal, then suggests to the moving tube It manages entity and carries out capacity adjustment；

In addition, if the E-RAB release that mobile management entity is initiated is the E-RAB release initiated due to gateway (SGW) Request, solution are as follows: it is recommended that associated release signaling Delete Bearer Request is searched on S11 mouthfuls, according to this As indicating in method, value the reason of IE field, carries out Primary Location to questions and prospect, and then specifically ask again in lookup signaling Topic concrete analysis.
