Description
Technical field
The present invention relates to the network communications technology, particularly a kind of user of prevention uses the method and the gateway device of call-back service.
Background technology
At present, the fixed network operator has opened a kind of call-back service towards the mobile subscriber, this business at current a big chunk mobile subscriber respectively as the calling party when conversing as the callee, telephone expenses exist aspect collecting than big-difference, by the switching of system platform, mobile subscriber's caller breathed out becomes called answering.
Fig. 1 is the schematic network structure that realizes call-back service in the prior art, and as shown in Figure 1, the mobile network is made up of end office (EO) and each gateway device, and fixed network is made up of end office (EO), gateway device and call-back service intelligent platform.
End office (EO) is responsible for professional access, and gateway device mainly plays the tandem function in network.When this network users makes a call to other provider customer, at first route the call to gateway device by end office (EO), route the call to the gateway device of respective operator again by the Home Network gateway device, the incoming call process is then just in time opposite; The call-back service intelligent platform is in order to realize callback facility.
When the fixed network user made a call, clawback was waited in fixed network call-back service intelligent platform prompting mobile subscriber on-hook to the mobile subscriber as the calling party; After mobile subscriber's on-hook, make a call to the mobile subscriber, and after the mobile subscriber replys, make a call to the fixed network called subscriber by intelligent platform again by intelligent platform; If the fixed network user replys, then both sides' talk line is set up
Below in conjunction with accompanying drawing, this professional implementation procedure is described in further detail, Fig. 2 is the realization flow figure of fixed network call-back service, as shown in Figure 2, may further comprise the steps:
Step 201: mobile subscriber A makes a call to fixed network user C.
Fixed network has forwarded this calling to call-back service intelligent platform B by its gateway device, does not hold so the calling of mobile subscriber A has the real fixed network user C that is sent to.
Step 202: call-back service intelligent platform B sends prompt tone to mobile subscriber A, prompting user on-hook.
Step 203: mobile subscriber A receives on-hook behind the prompt tone.
Step 204: call-back service intelligent platform B makes a call to mobile subscriber A.
Step 205: mobile subscriber A is to call-back service intelligent platform B loopback ring back tone.
Step 206: mobile subscriber A replys calling.
Step 207: call-back service intelligent platform B makes a call to fixed network user C.
Step 208: fixed network user C is to call-back service intelligent platform B loopback ring back tone.
Step 209: fixed network user C replys calling, and the circuit of finishing both call sides connects.
Step 210: divert from one use to another user A and called fixed network user C converses normally.
Like this,,, wait for the clawback of opposite end, can reduce the network completion rate, the waste Internet resources if a large number of users on-hook at once after making a call is arranged in the network for mobile operator.
In order to address this problem, a kind of method that increases static blacklist list in mobile network's gateway device has been proposed in the prior art, this static state blacklist list is by manually safeguarding, is used to write down used or suspect the mobile subscriber who has used call-back service.When the mobile subscriber who is put into static blacklist list when the fixed network user makes a call, gateway device is directly with this Call Intercept, forbids that conversation carries out.But this method exists certain drawback: gateway device is directly tackled the calling that the mobile subscriber initiates, and can make the user think that problem has appearred in the mobile network, is owing to oneself used due to the call-back service and be unaware of; Even some mobile subscriber recognizes the problem place, want to cancel this call-back service, but gateway device has been tackled the all-calls that these mobile subscribers initiate to external user, the calling that is included in fixed network end cancellation call-back service also can't be dialed, this just makes the user can't cancel call-back service, and then causes these mobile subscribers all the time can't normal talking.
As seen, the method that this prevention mobile network user makes a call to the fixed network user not can solve the reduction network completion rate of using call-back service to cause owing to the user, the problem of waste Internet resources.
Summary of the invention
In view of this, the main purpose of the embodiment of the invention is to provide a kind of user of prevention to use the method for call-back service, and this method can improve the network completion rate, and Internet resources are fully used.

Embodiment
Core concept of the present invention is: the Home Network gateway device obtains suspicious call-back service and uses user profile; When the outside network users of this network users makes a call, if determining that the user is suspicious call-back service, described gateway device uses the user, then write down this user's user ID; In the predefined time period,, then forbid this time calling out if described gateway device receives the callback of using the corresponding opposite end network of user to send with the suspicious call-back service that is write down.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 3 is the structural representation of first preferred embodiment of gateway device of the present invention, and as shown in Figure 3, this gateway device mainly is made up of blacklist list module 301, data interception module 302, time block 303 and routing module 304.
Wherein, blacklist list module 301 is used for the blacklist list that the suspicious call-back service of stored record uses user profile;
When the outside network users of this network users makes a call, whether data interception module 302 this user of inquiry in the blacklist list module 301 is that suspicious call-back service uses the user, if then write down this user's user ID, and start time block 303 as timer, by routing module 304 this customer call is routed to the opposite end network simultaneously, waits for the clawback of opposite end network; Otherwise, customer call is sent to routing module 304, route the call to the outer net end to realize normal talking by routing module 304; If in the time that time block 303 is set, receive callback from the outer net end, then data interception module 302 determines that this user has used call-back service, forbid this calling, if do not receive then this user of deletion record in the data interception tabulation user ID of callback.
In the present embodiment, the blacklist list that is used in the blacklist list module 301 write down suspicious call-back service use user profile is manually safeguarded by operator for static blacklist list.Such as, if operator monitors certain user call-back service of having contracted by third party device, then manually this user is joined in the static blacklist list; If operator monitors certain user among the static blacklist list in the stipulated time after sending calling, do not receive the callback that the opposite end network is initiated, then this user does not use call-back service, thereby manually this user is deleted from static blacklist list, in addition, suspicious call-back service uses user's information also can obtain automatically by dynamic blacklist list in the Home Network gateway device.
Fig. 4 is the structural representation of second preferred embodiment of gateway device of the present invention, compares with embodiment shown in Figure 3, and the difference of present embodiment is to have increased monitoring module 4011 and gray list list block 4012.
Described monitoring module 4011 is used to monitor the calling that the outside network users of this network users is initiated, and makes a call moment of back on-hook monitoring this network users, and this user's user ID is sent to gray list list block 4012;
Described gray list list block 4012 receives the user ID from monitoring module 4011, is recorded in the dynamic gray list tabulation that sets in advance; And judge in the time period that time block 303 is set whether receive the callback that the opposite end network is initiated at this user, be then to write down the callback number of times one time, otherwise deletion record this user ID in dynamically gray list is tabulated; After this every initiation call of this user and receive callback after, accumulative total callback number of times adds one; When accumulative total callback number of times reaches predetermined largest cumulative callback frequency threshold value, this user ID is recorded in the dynamic blacklist list that sets in advance in the blacklist list module 4013.
Like this, promptly realized generating dynamic blacklist list automatically by gateway device, other functions of modules and embodiment one are similar, repeat no more.
Fig. 5 is the flow chart of first preferred embodiment of the inventive method, supposes that Home Network is the mobile network, and outer net is a fixed network, as shown in Figure 5, may further comprise the steps:
Step 501: mobile network's gateway device obtains the information that suspicious call-back service uses the user by the static blacklist list that sets in advance.
The record Mobile Network Operator is suspected the mobile subscriber's who has used call-back service user ID in this static state blacklist list.
Step 502: when certain user among the mobile network when the fixed network user makes a call, mobile network's gateway device judges whether this user's user ID has been recorded in the static blacklist list: if do not have, then allow this user to converse by usual channel and fixed network user, and behind end of conversation process ends; If be recorded in the static blacklist list, then execution in step 503.
Step 503: gateway device is recorded in this user ID in the data interception tabulation that sets in advance
The tabulation of this data interception is used for writing down the mobile subscriber's who is recorded in static blacklist list and makes a call to the fixed network user user ID.
Step 504: start the timer in the gateway device, wait for the callback of fixed network end.
Step 505: in the time period that timer is set, the gateway device inspection whether received that the fixed network end initiates be recorded in the data interception tabulation in the corresponding callback of user, if receive, then execution in step 506, otherwise, execution in step 507.
Step 506: tackle this fixed network and call out, forbid that both sides converse, process ends.
Step 507: the gateway device deletion is kept at the user ID of this mobile subscriber in the data interception tabulation, and artificial simultaneously deletion is kept at the user ID of this mobile subscriber in the static blacklist list, process ends.
Fig. 5 is a realization situation of the present invention when mobile network's end has only a gateway device, in the practical application, may there be a plurality of gateway devices among the mobile network, and the callback of fixed network might be by any one gateway device access to mobile network wherein, therefore, in order comprehensively to stop the callback of fixed network end, the present invention also further comprises: keep the data sync between each gateway device, guarantee that the user ID of record in the data interception tabulation in each gateway device is up-to-date information.This process can send the data synchronization message that comprises user ID and realizes by being increased in above-mentioned steps 504 between each gateway device.
The transmission of data synchronization message can have multiple mode, such as, can be by current record the gateway device of up-to-date user profile send data synchronization message respectively to other gateway device; Also can be earlier by current record the gateway device of up-to-date user profile data synchronization information is issued the gateway device that is adjacent, send to next adjacent gateway device etc. by its adjacent gateway device again.
Fig. 6 is the flow chart of another preferred embodiment of the inventive method, compare with embodiment illustrated in fig. 5, the dynamic blacklist list that adopted present embodiment writes down suspicious call-back service and uses user profile, and step 601～605 are the generative process of dynamic blacklist list:
Step 601: Mobile Network Operator is provided with monitoring function at network gateway device place, be used for monitoring in real time the calling that mobile network user is initiated to the fixed network user, and the moment of on-hook after the mobile subscriber who is monitored makes a call, the user ID of sending this calling is recorded in the dynamic gray list tabulation that sets in advance, this dynamic gray list tabulation is that the user who is write down is provided with accumulative total callback number of times parameter and largest cumulative callback frequency threshold value, and starts timer.
Step 602: in the time period that timer is set, gateway device detects whether receive the callback at mobile subscriber described in the step 601 that the fixed network end is initiated, if receive, then execution in step 604, otherwise, execution in step 603.
Step 603: with the deletion from dynamic gray list tabulation of this user record, process ends.
In this step, described user record comprises this user's user ID and the accumulative total callback number of times parameter corresponding with this user.
Step 604: the accumulative total callback number of times of this user in the dynamic gray list tabulation is added one;
After this, callback has also taken place in the every initiation call of this user, and dynamically this user's accumulative total callback number of times will add one in the gray list tabulation.
Step 605: if user's accumulative total callback number of times reaches predetermined largest cumulative callback frequency threshold value,, think that then this user has used the fixed network call-back service, this user's user ID is added dynamic blacklist list such as 5 times.
According to above step, promptly in gateway device, generate suspicious call-back service automatically and used the dynamic blacklist list of user, step 502～507 are similar among subsequent processes step 606～611 and Fig. 5, repeat no more.Need to prove, when there is a plurality of gateway device in mobile network's end, need between each gateway device, send data synchronization message equally in the present embodiment, want data in synchronization not only to comprise the data interception table data this moment, also comprises dynamic gray list tabulation and dynamic blacklist list data simultaneously.
As seen, after having adopted technical scheme of the present invention, after the callback calling of certain this network users is prevented from continuously several times, this user will abandon continuing to use this call-back service, converse as calling party and external user according to normal method of calling, thereby improved the network completion rate, avoided waste of network resources.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
