Abstract
The invention discloses a method, a device and a system for establishing a call. The method for establishing the call comprises the following steps of: detecting state information of a signaling channel at a called terminal by a network side; when the signaling channel at the called terminal is busy, starting timing and suspending the call; in the timing period, detecting the state information of the called terminal at every predetermined time; and when the signaling channel of the called terminal is idle, continuing calling. By the method, the device and the system for establishing the call, when the signaling channel is temporarily used, the call is not cancelled at once, but the timing is started and the call is suspended a period of time; and if the signaling channel is restored to be idle in the timing period, calling is continued. Therefore, the condition that the initial call of a user is not responded is reduced; the complaint amount of users is reduced; and the network quality and user perception are improved.
Description
Technical field
The present invention relates to GSM switching network field, relate in particular to a kind of call-establishing method, Apparatus and system.
Background technology
When the called mobile phone user is is receiving and dispatching note in the communication network, the occupied signaling channel, this user is can not the call accepted state, calls out this user's failure this moment.
As (the Mobile Switching Centre of a 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 the called subscriber can accept this time to call out, MSC can be at first by sending information (SendInformation For Incoming Call for calling, abbreviation SIFIC) message is to corresponding VLR Visitor Location Register (Visitor Location Register, abbreviation VLR) relevant this called subscriber's of inquiry user profile, VLR passes through searching user's information, can accept this time to call out (not shutdown and permission call accepted) if find this user, can send paging command message to MSC, in this message, contain user position information (Location area identity, be called for short LAI)), after MSC receives this information, data query, the base station controller of controlled this lane place (Base Station Controller, abbreviation BSC) signaling point code, to the order of corresponding BSC distributing paging, finish call proceeding.But the VLR searching user's information is found the cellphone subscriber in transmitting-receiving note process, the occupied signaling channel, and this user can not accept this time to call out, and returns negative affirmation, and MSC sends out disconnect command to the calling party, call failure.
As shown in Figure 1, in the prior art network mobile phone user to be called out idiographic flow in transmitting-receiving during note 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 be at first by the user profile of S.F.I.C message to relevant this called subscriber of corresponding VLR-B inquiry, and VLR-B is by searching user's information, and the cellphone subscriber is in transmitting-receiving note process, and the occupied signaling letter is logical, and this customer 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.
There is following defective in by the call technology scheme in existing mobile phone user when the transmitting-receiving note:
(1) after a MSC of end office (EO) receives the IAM message of its office's transmission, MSC can be at first by the user profile of S.F.I.C message to relevant this called subscriber of corresponding VLR inquiry, VLR passes through searching user's information, find that the cellphone subscriber is in transmitting-receiving note process, the occupied signaling channel, this user can not accept this time to call out, and MSC can't be to the order of BSC distributing paging, call failure;
(2) because the called subscriber is receiving and dispatching the paged failure of note, and then cause the phenomenon of access failure in existing network, to exist, this problem causes GSM network head not exhale should (calling out called obstructed for the first time, call out for the second time and can connect again) complain account for all GSM network head exhale should not complain 30%, along with the short message service kind increases, cellphone subscriber's note amount increases, mobile phone called probability in transmitting-receiving note process is more and more, the head that this problem causes exhales and should not complain increasingly, has a strong impact on user's proper communication.
