Description
Technical field
The present invention relates to a kind of method that realizes back call service in treating busy in the mobile communication.
Background technology
As everyone knows, in the process of using mobile terminal device to call out, if called subscriber busy will cause call loss.Usually, in this case, the mobile subscriber can only wait for that the suitable time initiatively calls out once more.Through statistics, because called subscriber busy, and other called foundation failures and the call loss that causes is equivalent to 1%～3% of whole number of call attempts.Thus, for this part calling is retrieved in meeting, second adds the stage, and (Phase 2
+) global system for mobile communications (GSM) standard and Wideband Code Division Multiple Access (WCDMA) (WCDMA) standard in its supplementary service, defined Call Back when Busy (CCBS:Completion ofCalls to Busy Subscriber) business.Support the mobile network of CCBS business, at called subscriber busy, perhaps current no available air traffic channel resource and cause calling out under the situation about can't carry out, can be when called subscriber subsequently be idle, when available air traffic channel resource is perhaps arranged, point out calling subscriber called subscriber's this moment idle automatically, and initiatively initiate a call to the calling subscriber, therefore the calling subscriber can select to continue, and this is called out, and finishes original calling.This shows, use the call completing rate that the CCBS business can improve whole system, also reasonable use air traffic channel resource more simultaneously increases by similar 2% income to operator.
Support GSM Phase 2
+The mobile communication system of the CCBS business that agreement defines in its supplementary service in calling procedure, if find called subscriber busy, can allow the calling subscriber to activate the CCBS supplementary service.Like this, network is the state of monitor called user at any time, in case the called subscriber becomes the free time, network will wait for a period of time, and during this period, network allows the called subscriber to initiate outside calling.If the called subscriber does not make a call, network thinks that then the called subscriber is in idle condition really, and at this moment, network is with automatic callback calling subscriber.When the calling subscriber receives the CCBS callback of network, network also will produce a CCBS automatically and call out to the called subscriber.This moment, the calling subscriber can initiate different basic services to the called subscriber, produced different CCBS requests, realized CCBS thus.
But, need to prove that the calling subscriber of realization CCBS business and called subscriber's network are all supported this CCBS business, promptly realize the calling subscriber equipment of CCBS business and called subscriber's all necessary GSM of the support Phase 2 of network
+Agreement.Specify as follows:

As shown in Figure 3, the dotted line among Fig. 3 mainly is divided into following 4 stages with the CCBS service call flow process of success:
Phase I: in the initial condition stage, promptly during initial call, called network is determined called subscriber's state for busy, and the prompting calling subscriber can activate the CCBS business.Specifically may further comprise the steps:
301, calling subscriber's mobile station MS 1 sends and sets up the mobile switching centre/Visited Location Registor MSC/VLR1 of message to caller, sets up and calls out;
302, calling mobile exchanging center/Visited Location Registor MSC/VLR1 finds the signatory CCBS business of user according to user contracting data, then send Initial Detection Point message to SCP, carry calling subscriber's CCBS business information in this message, SCP sets up CCBS business relations between calling subscriber and the called subscriber according to the CCBS business information;
Wherein, the CCBS business relations are meant that SCP detects the state of this calling, and in called subscriber busy, start the process that CCBS calls out;
303, calling mobile exchanging center/Visited Location Registor MSC/VLR1 sends initial address message to gateway MSC (GMSC) according to called subscriber's MSISDN, seeks the called subscriber by GMSC;
304, after GMSC receives initial address message, send information request message to called attaching position register HLR2, request called subscriber's MSRN according to called subscriber's MSISDN;
305, called attaching position register HLR2 sends and Provides Roaming Number message to called mobile switching centre/Visited Location Registor MSC/VLR2; The MSRN that called mobile switching centre/Visited Location Registor MSC/VLR2 returns the called subscriber gives called attaching position register HLR2;
306, called attaching position register HLR2 returns to GMSC with called subscriber's MSRN sign indicating number in information request response message;
307, GMSC sends initial address message to called mobile switching centre/Visited Location Registor MSC/VLR2 according to called subscriber's MSRN, calls out the called subscriber;
308, called mobile switching centre/Visited Location Registor MSC/VLR2 detects called subscriber busy, then returns release message and gives GMSC, and the mark release cause is a called subscriber busy, indicates called network simultaneously and supports the CCBS business;
309, GMSC passes to calling mobile exchanging center/Visited Location Registor MSC/VLR1 with the release message that receives;
310, calling mobile exchanging center/Visited Location Registor MSC/VLR1 is by Event Detection Point information reporting SCP, and called subscriber's state is for busy; SCP control calling mobile exchanging center/Visited Location Registor MSC/VLR1 and calling subscriber carry out alternately, select whether to activate the CCBS business;
311, calling mobile exchanging center/Visited Location Registor MSC/VLR1 and calling subscriber carry out alternately, prompting calling subscriber called network is supported the CCBS business, determine whether the calling subscriber selects to activate the CCBS business, and after the calling subscriber selects, discharge calling subscriber's Traffic Channel.
In the present embodiment, above-mentioned reciprocal process is specially: calling mobile exchanging center/Visited Location Registor MSC/VLR1 plays voice suggestion message for the calling subscriber, and the prompting calling subscriber can select to activate the CCBS business; The calling subscriber is according to voice suggestion, by select whether to activate the CCBS business by the button of appointment on the cell phone keyboard.
For example, in the voice suggestion of playing, the prompting user dials 1 expression and activates the CCBS business after hearing prompt tone, dial 0 expression and do not activate the CCBS business, then the calling subscriber represents not activate the CCBS business representing to select to activate the CCBS business by 1 button on the cell phone keyboard behind the prompt tone by 0 button on the mobile phone.
In addition, in this step, the calling subscriber is when activating the CCBS business, also to set the time span that called mobile switching centre/Visited Location Registor MSC/VLR2 monitors called subscriber condition, if surpass the time of setting, the called subscriber is still unavailable, then this CCBS calling service failure, and called mobile switching centre/Visited Location Registor MSC/VLR2 stops the monitor called user state.For example, if the supervision duration that the calling subscriber sets is 30 minutes, if then surpass 30 minutes, the called subscriber does not still have idle available, then this CCBS calling service failure, SCP controls called mobile switching centre/Visited Location Registor MSC/VLR2 and stops the monitor called user state.The time span of described supervision called subscriber condition also can be provided with by above-mentioned reciprocal process.
In order to realize above-mentioned reciprocal process, SCP will be mapped number and the corresponding C CBS business operation that the user dialled in advance.For example, if subscriber dialing 1, expression selects to activate the CCBS business, and then SCP needs at first to be mapped with the operation that activates the CCBS business 1.
So far, the calling subscriber can activate the CCBS business, and called subscriber's free time is waited in on-hook; Also can select not activate the CCBS business.If the calling subscriber selects not activate the CCBS business, this end of calling (not showing among Fig. 3) then.
Second stage: in the activation stage, promptly the calling subscriber activates the CCBS business.Concrete steps are as follows:
312, after the calling subscriber selects to activate the CCBS business, calling mobile exchanging center/Visited Location Registor MSC/VLR1 will report the incident of called subscriber busy to give SCP, and SCP starts the CCBS business according to the incident that reports;
313, SCP sends random time and revises message to called attaching position register HLR2, revises the professional relevant intelligent data with CCBS;
Wherein, the above-mentioned intelligent data relevant with the CCBS business comprises: called subscriber's user data, CCBS business datum, Supplementary Service Code (SS-CODE), Looking Out Time, mobile management subscription data, Service Control Function address etc.;
314, called attaching position register HLR2 is by inserting subscriber data message, to be inserted into called mobile switching centre/Visited Location Registor MSC/VLR2 from the intelligent data relevant of SCP with the CCBS business, the CCBS activation tagging is set, control called mobile switching centre/Visited Location Registor MSC/VLR2 and monitor called subscriber condition, return the response message that inserts user data simultaneously;
315, after called attaching position register HLR2 receives above-mentioned response message, send random time and revise message response, the called mobile switching centre of notice SCP/Visited Location Registor MSC/VLR2 begins to detect called subscriber condition.
