Description
Technical field
The present invention relates to GSM switching network field, particularly relate to a kind of call-establishing method, Apparatus and system.
Background technology
When in communication network, called mobile phone user is is receiving and dispatching note, occupied signaling channel, this user is can not call accepted state, now calls out this user's failure.
As a mobile switching centre (Mobile Switching Centre, be called for short MSC) receive initialization address message (the Initial Address Message that its office sends, be called for short IAM) after, in order to determine whether called subscriber can accept this time calling, MSC can first by sending information (SendInformation For Incoming Call for calling, being called for short SIFIC) message is to corresponding VLR Visitor Location Register (Visitor Location Register, being called for short VLR) inquiry is about the user profile of this called subscriber, VLR passes through searching user's information, if find that this user can accept this time calling (do not shut down and allow call accepted), paging command message can be sent to MSC, within the message, positional information (Location area identity containing user, be called for short LAI)), after MSC receives this information, data query, obtain base station controller (the Base Station Controller controlling this lane place, be called for short BSC) signaling point code, to the order of corresponding BSC distributing paging, complete call proceeding.But VLR searching user's information, find that cellphone subscriber is in transmitting-receiving note process, occupied signaling channel, this user can not accept this time calling, and return the confirmation of negative, MSC sends out disconnect command to calling party, call failure.
As shown in Figure 1, in prior art network, mobile phone user called idiographic flow when receiving and dispatching note is as follows:
1, MSC-B receives the initial address message (Initial Address Message is called for short IAM) of its office's transmission;
2, MSC-B can first by the user profile of S.F.I.C message to corresponding VLR-B inquiry this called subscriber relevant, and VLR-B is by searching user's information, and cellphone subscriber is in transmitting-receiving note process, and occupied signaling letter leads to, and this user's call state is not for accepting;
3, VLR-B returns Negative Acknowledgement to MSC-B;
4, MSC-B sends out clear message to calling side MSC-A, call failure.
Following defect is there is in called technical scheme in existing mobile phone user when receiving and dispatching note:
(1) after an end office (EO) MSC receives the IAM message of its office's transmission, MSC can first by S.F.I.C message to the user profile of corresponding VLR inquiry about this called subscriber, VLR passes through searching user's information, find that cellphone subscriber is in transmitting-receiving note process, occupied signaling channel, this user can not accept this time calling, and MSC cannot to the order of BSC distributing paging, call failure;
(2) because called subscriber is carrying out the paged failure of transmitting-receiving note, and then cause the phenomenon of access failure to exist in existing network, this problem cause GSM network head exhale should (first time not call out called obstructed, second time calling can connect again) complain account for all GSM network head exhale should not complain 30%, along with short message service kind increases, cellphone subscriber's note amount increases, mobile phone called probability in transmitting-receiving note process gets more and more, the head that this problem causes exhales and should not complain increasing, has a strong impact on user's proper communication.

Embodiment
Call-establishing method of the present invention and system, can be applied to signaling channel by under temporary transient seizure condition, as user sends note etc.Below in conjunction with accompanying drawing, the present invention is described in detail.
embodiment of the method
As shown in Figure 2, the idiographic flow of call-establishing method embodiment of the present invention is as follows:
Step 202, MSC-A sends IAM to MSC-B;
Step 204, MSC by SIFIC message to the state information of corresponding VLR-B inquiry about this called subscriber;
Step 206, VLR-B deposits the state information of user terminal, when user terminal is in transmitting-receiving note process, occupied signaling channel, now this user can not accept this time calling, VLR-B Return Channel temporary message, display signaling channel state is hurried, and the message that VLR is reported to MSC is GSM specification message;
Step 208, MSC-B receives this channel temporary message, starts timing, suspension calling;
Step 210, VLR-B is within the timing phase, the state information of described terminal called is detected every the scheduled time, this scheduled time should be less than timing duration, when detecting that user terminal receive note terminates, signaling channel is idle, then VLR-B Return Channel idle message is to MSC-B, display signaling channel idle;
Step 212, when MSC-B receives channel idle message, timer does not exceed default time value, then to the order of BSC-B distributing paging, replay call;
Step 214, when MSC-B does not also receive channel idle message when timing expires, sends clear message to MSC-A, then cancels calling.
In the present embodiment, timing also can be carried out in VLR-B, and when VLR-B detects the signaling channel busy of described terminal called, VLR-B starts timing, and notifies that described MSC suspends calling.
The call-establishing method of the present embodiment, by not being cancel calling at once when signaling channel temporary, but starts timing, suspension calling a period of time, if signaling channel recovers idle within the timing phase, then and replay call.Like this, the defect that when making up user terminal channel temporary, called cannot be connected, decreases user head and exhales the situation of not answering, reduce customer complaint amount, improve network quality, improve user awareness.
device embodiment one
As shown in Figure 3, VLR embodiment of the present invention comprises:
