Fig. 1 is a flow chart of realizing embodiments of the invention when audio call during for ordinary call.Referring to Fig. 1, when audio call is ordinary call, take Internet resources for a long time for fear of audio call, the present invention proposes a kind of method of dismantling call, its specific implementation process may further comprise the steps:
Step 101: in mobile switching centre (MSC), timer is set in advance.
Step 102: the corresponding relation that different user sign and different call duration threshold values are set in MSC in advance.
Here, in order to satisfy the different business needs of different user, the present invention can further be provided with different call duration threshold values to different user, that is to say, for the higher user of priority, can allow it to have the more duration of call,, allow it to have the less duration of call for the lower user of priority.Described user ID can be for characterizing the Subscriber Number of User Priority.
Step 103: in MSC, be provided with in advance and continue to call out pairing terminal push signal.
Here, owing to the conversation that abnormal conditions cause is overtime, the user of audio call can in time not continue the information of conversation usually to the network side feedback in communication process.This be because, break down for network equipment and to make audio call hang and the conversation that causes is overtime, the information that user feedback continues conversation can't be notified and receive to network side, to connect to come malice to take the conversation that Internet resources cause so that network equipment is attacked overtime and do not discharge audio call for a long time for the disabled user, the disabled user can not wait for usually by terminal, just can't continue the information of conversation to the network side feedback yet.On the contrary, overtime for the conversation that normal talking causes, the user of audio call can in time continue the information of conversation to the network side feedback in communication process, therefore, be provided with in this step and continue to call out pairing terminal push signal, so that in subsequent process, network side can further confirm whether need to continue conversation to the user.
In addition, need to prove that the MSC described in step 101, step 102 and the step 103 is meant any one MSC of network side.
Step 104: the calling subscriber sets up and being connected of called subscriber by network side.
The specific implementation process of this step is a prior art, is not described in detail herein.But it should be noted that described calling subscriber and called subscriber set up is connected and is through the MSC's of network side.
Step 105: when receiving called subscriber's off hook signal, this connects related MSC and start the timer that is provided with in advance in self.
Here, described startup timer is to instigate this timer to pick up counting from 0.
Step 106: this connects related MSC and find the call duration threshold value corresponding with this user's sign in the corresponding relation of the different user sign that sets in advance and different call duration threshold values.
Here this user's of the following stated sign is this user's of being obtained when the connection of setting up this calling of described MSC a number and in the present embodiment.
Step 107: in the communication process of calling subscriber and called subscriber's audio call, this connects the currency that related MSC obtains timer.
Step 108: whether this connects currency that related MSC judges the timer that is obtained greater than the call duration threshold value that is found, if then execution in step 109, otherwise, return step 107.
Step 109: this connects related MSC and sends the affirmation call message to this user, judge that then whether receiving the continuation that this user sends by its terminal in the predefined time period calls out pairing terminal push signal, if, then execution in step 110, otherwise, execution in step 111.
Step 110: this connects the communication process that related MSC keeps calling subscriber and called subscriber's audio call, and is enabled in the timer that is provided with in self again, returns step 107.
Step 111: this connects related MSC and triggers the process that current speech is called out of removing, and each entity of network side is removed current audio call.
Here, MSC trigger to remove the process that current speech is called out, and each entity of network side to remove the process that current speech calls out be prior art, no longer describe herein.
In the present embodiment, it is caller MSC or called MS C that described this connects related MSC, that is to say, in the audio call process of calling and called, can carry out the process of above-mentioned steps 105 to step 111 by caller MSC or called MS C.
In addition, described this user is calling subscriber or called subscriber, that is to say, in above-mentioned steps 106 and step 109, at this user can be that the calling subscriber also can be the called subscriber.
Embodiment 2:
Present embodiment is intelligent call with the audio call, and judges that by the overtime duration of the timer that sets in advance whether the duration of call of audio call is example greater than the call duration threshold value that sets in advance, and implementation procedure of the present invention is described.
Fig. 2 is a flow chart of realizing embodiments of the invention when audio call during for intelligent call.Referring to Fig. 2,, that is to say that when the user of audio call is intelligent subscriber, take Internet resources for a long time for fear of audio call, the specific implementation process of the dismounting voice call method that the present invention proposes may further comprise the steps when audio call is an intelligent call:
Step 201: timer and overtime duration thereof are set in Service Switching Point in advance.
The overtime duration of timer can be set according to the empirical value to normal talking duration statistics gained here.Such as, value rule of thumb, the normal talking duration is less than 3 hours, and then in this step, overtime duration that can timer is set to 3 hours.
Step 202: user ID and the corresponding relation of whether carrying out dismounting are set in SSP in advance.
Here, in order to satisfy the different business needs of different user, the present invention can further adopt different call treatment strategies to the different intelligent user, that is to say, for the higher intelligent subscriber of priority, can allow it to carry out the conversation of ultra-long time, for the lower intelligent subscriber of priority, do not allow it to carry out the conversation of ultra-long time, therefore, in this step, user ID and the corresponding relation of whether carrying out dismounting are set, described user ID is the Subscriber Number that can characterize intelligent subscriber priority or the address of the Service Control Point under the user.
Step 203: in SSP, be provided with in advance and continue to call out pairing terminal push signal.
Here, owing to the conversation that abnormal conditions cause is overtime, the user of audio call can not continue the information of conversation usually to the network side feedback in communication process, and the conversation that normal talking causes is overtime, the user of audio call can continue the information of conversation to the network side feedback in communication process, therefore, be provided with in this step and continue to call out pairing terminal push signal, so that in subsequent process, network side can be further confirms whether to continue conversation to the user of normal talking.
In addition, need to prove that the SSP described in step 201, step 202 and the step 203 is meant any one SSP of network side.
Step 204: the calling subscriber sets up and being connected of called subscriber by network side.
The specific implementation process of this step is a prior art, is not described in detail herein.But need to prove because this audio call is intelligent call, so calling subscriber and called subscriber set up be connected MSC, SSP and the SCP that passes through network side.
Step 205: when receiving called subscriber's off hook signal, this is called out related SSP and start the timer that is provided with in advance in self.
Here, described startup timer is to instigate timer to pick up counting from 0.
Step 206: after the overtime duration of timer arrived, this was called out related SSP and judges whether the connection of this audio call still keeps, if then execution in step 207, otherwise, finish current flow process.
By this step as can be seen, in the present embodiment, be that overtime duration with timer is as a call duration threshold value, whether still keep by judging, judge that whether the duration of call of this audio call is the call duration threshold value greater than the overtime duration of timer in the connection of the overtime duration of timer to this audio call of back.
Step 207: this is called out related SSP and judges whether to remove current calling according to the corresponding relation of this user's sign and the preset user sign dismantling call with whether, if, then execution in step 208, otherwise, keep the communication process of calling subscriber and called subscriber's audio call, finish current flow process.
The specific implementation process of this step is: this calls out related SSP finds this user in the corresponding relation of preset user sign dismantling call with whether sign, in this corresponding relation, if the user ID correspondence that is found is dismantling call, then think and to remove current calling, if the user ID correspondence that is found is dismantling call not, then not thinks and to remove current calling.
Need to prove this user's of this step and present embodiment the following stated number that is designated this user that SSP obtained when connecting or the address of the SCP under this user.
Step 208:SSP sends the affirmation call message to this user, judge that then whether receiving the continuation that this user sends by its terminal in the predefined time period calls out pairing terminal push signal, if, the communication process that then keeps calling subscriber and called subscriber's audio call, and be enabled in the timer that is provided with in self again, return step 206, otherwise, execution in step 209.
Step 209:SSP triggers the process that current speech is called out of removing, and each entity of network side is removed current audio call.
Here, SSP trigger to remove the process that current speech is called out, and each entity of network side to remove the process that current speech calls out be prior art, no longer describe herein.
In above-mentioned flow process shown in Figure 2, in step 205, when receiving called subscriber's off hook signal, this calls out related SSP also can directly not start timer, but at first judge in subsequent process, whether can remove current calling according to the corresponding relation of this user's sign and preset user sign dismantling call with whether, if can not, then need not to carry out subsequent step, turn to and carry out the process that existing maintenance audio call connects, if the step that starts timer is then carried out in meeting again, correspondingly, in subsequent step, then need not execution in step 207, directly execution in step 208 gets final product.
In present embodiment 2, it is calling SSP or called SSP that described this connects related SSP, that is to say, in the audio call process of calling and called, can carry out the process of above-mentioned steps 205 to step 209 by calling SSP or called SSP.
In addition, described this user is calling subscriber or called subscriber, that is to say, in above-mentioned steps 207 and step 208, at this user can be that the calling subscriber also can be the called subscriber.
Need to prove, in present embodiment 2, the setting up procedure that is carried out in step 201, step 202 and step 203 also can be finished on any one MSC of network side or SCP, correspondingly, process from step 205 to step 209 is to be finished by this intelligent call related MSC or SCP, and the principle of its specific implementation process is identical with the said process principle.
It should be noted that also the foregoing description 1 and embodiment 2 just the present invention is directed to ordinary call and intelligent call and the process of a kind of possible dismounting audio call that adopts respectively.That is to say, whether the duration of call that the present invention judges audio call by the timer that sets in advance or timer is not distinguish ordinary call and intelligent call greater than the process of the call duration threshold value that sets in advance, promptly, in above-mentioned embodiment 1 at ordinary call, also whether the duration of call that can judge audio call by the timer that sets in advance and overtime duration thereof is greater than the call duration threshold value that sets in advance, in above-mentioned embodiment 2, also can judge that whether the duration of call of audio call is greater than the call duration threshold value that sets in advance by the timer that sets in advance at intelligent call; In addition, the present invention identifies and whether carries out the corresponding relation of call tear down according to preset user, perhaps according to the corresponding relation of the different user sign that sets in advance with different call duration threshold values, determine whether that carrying out the process of removing audio call is not distinguish ordinary call and intelligent call equally, that is to say, in above-mentioned embodiment 1 at ordinary call, also can determine whether to carry out and remove audio call according to preset user sign and the corresponding relation of whether carrying out call tear down, in above-mentioned embodiment 2 at intelligent call, also can determine whether to carry out with the corresponding relation of different call duration threshold values according to the different user sign that sets in advance and remove audio call, the principle of its specific implementation process be identical with the principle of respective process among the foregoing description 1 and the embodiment 2.
