Abstract
The invention provides a method for calling control, and the method comprises the following step: after a call has been established, if a moving switching center and / or a base station controller judges that a link of control plane is disconnected, then the call is kept in media plane. The invention also provides a device for calling control, when a status judging unit of the device judges that the link of control plane is disconnected, the status judging unit notices a calling control unit. After the calling control unit receives the notice from the status judging unit, and if the call has been established, the call is kept in media plane. The invention also provides a base station controller and a moving switching center including the calling control device. The invention can keep the call even when the link of the control plane is disconnected.

Fig. 2 is a call control apparatus flow chart of the present invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, hereinafter will be elaborated to embodiments of the invention in conjunction with the accompanying drawings.Need to prove that under the situation of not conflicting, embodiment among the application and the feature among the embodiment be combination in any mutually.
Core concept of the present invention is: behind the call setup, medium face and chain of command can independently be opened fully, even chain of command disconnects, calling still can keep a period of time on the medium face.When MSC/BSC judges the chain of command chain rupture, start timer, in the timer scope, guarantee the proper communication of medium face, behind the timer expiry, initiate again to discharge.
The invention provides a kind of calling-control method, comprising:
Behind the call setup, mobile switching centre and/or base station controller keep this calling at the medium face after judging the chain of command chain rupture.
Wherein, described mobile switching centre and/or base station controller discharge described calling when receiving Client-initiated calling release signaling; Perhaps, a timer is set, described mobile switching centre and/or base station controller start this timer after judging the chain of command chain rupture, keep this calling to described timer expiry at the medium face, discharge described calling.Can a timer be set mobile switching centre, base station controller is provided with a timer, also can only one of them timer be set.
Wherein, described mobile switching centre or base station controller are judged the chain of command chain rupture in the following way: receive chain rupture message or active detecting to the chain of command chain rupture.Usually base station controller and mobile switching centre are by the whether chain rupture of handshake mechanism active detecting.
Below in conjunction with accompanying drawing the present invention being realized solving chain of command chain rupture between BSC and MSC describes the method for the influence of conversation.
In the following specific embodiment, suppose that user both sides have set up conversation.
Step 101, calling is in talking state, the SCCP of MSC (Signal Connect Control Point, SCCP) after layer detects chain rupture, operation layer to BSC sends chain rupture message SccpDisconnect, MSC starts timer, keeps calling out at the medium face in the timer timing;
Step 102 after the BSC operation layer is received chain rupture message, starts timer, keeps calling out at the medium face in the timer timing, promptly keeps the conversation of medium face.
Step 103, behind the timer expiry, BSC starts the release flow process, sends release command to MS, discharges MS (Mobile Station, travelling carriage).
Certainly, MSC and BSC also can not be provided with timer, keep calling out call release when the user initiatively makes a call release at the medium face.Also can MSC and BSC one of them timer is set, behind MSC that is provided with timer or BSC call release, be MSC or the BSC call release that timer is set.
The invention provides a kind of call control apparatus, described device comprises state judging unit and Call Control Unit, as shown in Figure 2, and wherein:
Described state judging unit is used for: after judging the chain of command chain rupture, and the notification call control unit;
Described Call Control Unit is used for: after receiving the notice of described state judging unit, set up if call out, keep this calling at the medium face.
Wherein, described Call Control Unit also is used for: when the user initiatively initiates to discharge described calling, discharge described calling.
Wherein, described device also comprises a timer, and described Call Control Unit is used for: after receiving the notice of described state judging unit, start described timer, keep this calling to described timer expiry at the medium face, discharge described calling.
Wherein, described state judging unit is to be used for: judge the chain of command chain rupture when receiving chain rupture message or active detecting to the chain of command chain rupture.
The present invention also provides a kind of mobile switching centre that comprises above-mentioned call control apparatus, and, a kind of base station controller that comprises above-mentioned call control apparatus.
The present invention receives chain rupture message in communication process after, can postpone call release, allow the user tell about dialog context as far as possible, improve user's impression.The present invention can solve the influence of chain of command chain rupture to conversing between BSC and MSC.
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the storage device and carry out by calculation element, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
