After obtaining SCCP connection article one message SCCP connection request message SCCP_CR; Preserve OPC in this message, DPC and three important informations of SLR; System produces the connection label distribution and connects to this, and OPC, three information of DPC and SLR are connected label with this and set up mapping relations.Said connection label is generated and is distributed to SCCP automatically and connects by system, one connects the corresponding unique SCCP connection of label, and connecting label can be letter, numeral or its combination.
2, upgrading SCCP connects and the mapping relations that are connected label
After obtaining connection acknowledge message SCCP_CC, extract the DLR in this message, upgrade the information of this connection label mapping.So far, set up this SCCP and connected the mapping relations that are connected label with this.
3, judge whether to connect into same SCCP
Judging whether to belong to this SCCP according to the OPC that carries in the message that receives, DPC, SLR or DLR and connect, is this message of distributing to that then will connect label; Otherwise, distribute new connection label and set up SCCP to connect and the mapping relations that are connected label.
4, set up the paging index, temporary beep-page message
Based on the Location Area Identification, international mobile subscriber identity IMSI, the temporary mobile subscriber identity TMSI that obtain in the beep-page message; And with Location Area Identification, IMSI and TMSI as keyword Key; Whether inquiry exists same paging index; Have then that explanation is the paging at same terminal, then under this paging index, store this message and sign in; Otherwise, set up a new paging index and under this paging index this message of storage with reach the time.In addition, be that the beep-page message of naming a person for a particular job before the scheduled time is deleted from the paging index with the current paging time, to guarantee the validity of storing message in the paging index, the span of the aforementioned scheduled time is 10-40 second.
5, judge whether to exist father CDR, carry out father CDR and synthesize
Whether there is father CDR according to connecting searching label; If exist then call out synthetic to this message; This message is joined current parent CDR message queue and gives sub-CDR synthesis module with this transmission of messages; Then; Judge according to table 1 whether this message is the CDR end, is then, finishes this father CDR; Otherwise, continue to receive message and synthetic; Judge further then if there is no whether this message is the SCCP_CR message of SCCP layer; If then explanation is that a new SCCP connects; Set up new father CDR; This message is called out synthetic, this message is joined current parent CDR message queue and gives sub-CDR synthesis module with this transmission of messages; If not the processing of then abandoning this message, finish the synthesis flow of this message.
Need to prove; If adopt the CDR sign to set up the incidence relation of father, sub-CDR, then when new father CDR is synthetic, generates the CDR sign automatically and distribute to this father CDR by system; The corresponding unique father CDR of father CDR sign, said CDR sign can be letter, numeral or its combination.Certainly, call out the incidence relation that composite key Key sets up father, sub-CDR, then can not distribute the CDR sign if adopt.
6, judge whether to exist the sub-CDR of the type, and carry out sub-CDR and synthesize
Confirm according to type of message and table 2 whether the Key of sub-CDR and inquiry exist this Key, if exist then explain that the pairing sub-CDR of this message exists, and calls out synthetic to this message; Message is joined current sub-CDR message queue; Then, judge according to table 1 whether this message is the CDR end, is then to close this sub-CDR; Otherwise, continue to receive message and synthetic; If do not exist then whether meet the requirement of creating the new sub-CDR of this type according to this message of the listed condition judgment of table 1; Meet and then set up new sub-CDR and call out synthetic this message; Message is joined this sub-CDR message queue, do not meet and then finish synthesis flow.
Need to prove; If adopt the CDR sign to set up the incidence relation of father, sub-CDR, then when new sub-CDR is synthetic, generates the CDR sign automatically and distribute to this sub-CDR by system; The corresponding unique sub-CDR of sub-CDR sign, said CDR sign can be letter, numeral or its combination.In addition, confirm and distribute should sub-CDR sign after, should sub-CDR identification record in father CDR, in this sub-CDR, write down father CDR simultaneously and identify.Certainly, if adopt to call out the incidence relation that composite key Key sets up father, sub-CDR, then can not distribute the CDR sign, but Key that will this sub-CDR is recorded among the father CDR, the Key with father CDR is recorded among this sub-CDR simultaneously.
In addition, can know that the sub-CDR of part type calls out synthetic same the employing and connects label as calling out composite key Key, generate by system equally, constitute by letter, numeral or its equally from table 2.Because the CDR type is different, can not cause obscuring of father CDR and sub-CDR, obscuring between the perhaps dissimilar sub-CDR.
In sum; Multi-service call synthetic method adopts the structure of tree type to call out synthetic to the repeatedly concurrent or related interacting message of multiple business type that exists in the SCCP connection in the gsm communication system of the present invention; All message that terminal of father's cdr logging is sent and received in a SCCP connects, type of service of each sub-cdr logging all message in a calling procedure; Father CDR can corresponding a plurality of sub-CDR, and each sub-CDR can write down the interacting message of the call process of same type of service; Father CDR comprises the entire message of sub-CDR.The massage set of sub-CDR is the subclass of father CDR massage set.
Because multi-service call synthetic method is being called out when synthetic in the gsm communication system of the present invention, set up the index that father CDR sign and sub-CDR identify, perhaps the index of the Key of the Key of father CDR and sub-CDR.Obviously; The index of CDR sign or Key is similarly tree structure, and the index through CDR sign or Key is easy to realize the two-way search between father, the sub-CDR, can in father CDR, see the global information in the whole connection; In sub-CDR, see the entire message of father CDR; Can see that every message is in position and relation in the whole message flow (being father CDR) among the sub-CDR, and, also can in sub-CDR, see detailed about these professional details of sub-CDR type of service.Having solved the prior art call synthetic method does not distinguish type of service when synthetic in that GSM network A interface message is called out; The CDR attribute does not have emphasis or bad differentiation; The not obvious monitoring analysis process difficulty that makes of message difference increases between the business; Reduced the problem of operating efficiency
