Description
Technical field
The present invention relates to the automatic re-dialing function of mobile communication system, particularly relate to calling connection failure to taking place in the communication service initial condition, under the hands-off situation of user, mobile communication terminal itself is redialed automatically, remove the mobile communication system automatic redialing method of user the inconvenience of the number repetition duplicate numbers that goes offline.
Background technology
Along with the development rapidly of the communication technology, mobile communication system is exploited, and makes the individual or move to another place from anywhere in arbitrary site and communicates with other people recently.In addition, described mobile communication terminal has also increased various value-added service function except that the simple call function that is provided at present.
On the one hand, the redialing function in described mobile communication terminal in the various value-added service function is meant, when the contrary direction visit failure of mobile communication terminal, and the method that mobile communication terminal attempts redials.When this method is failed in reverse visit, when whether the user's query of mobile communication terminal redials or set redialing function it is redialed automatically, the existing correlation technique that redials all is suitably to set the interval of attempting to redial and number of times and improve the success rate of attempting to redial.
Fig. 1 is for sending the flow chart of the basic call flow process of signal in the existing mobile communication system, detailed call flow can be presented as colorful various according to communication system.
As shown in Figure 1, be made up of following components: mobile communication terminal MS 10 makes a people can move to another place words that work of going forward side by side from any one place; Base station BS 20 is with described mobile communication terminal 10 wireless connections, with the mobile communication system of mobile communication terminal 10 that is connected with wired network by wireless network and catv terminal formation network; User Land30 forms network by described mobile communication terminal 10 and base station 20, puts through recipient's land phone or radiophone.
The general step that sends signal is (to see step S100) behind user's Outgoing Call, if with reverse addressing channel send SMS message (seeing step S101), the transmission signal of mobile communication terminal 10 is detected in then described base station 20, send invalid signal of communication (Null Traffic) (seeing step S102) with positive direction, and the channel (seeing step S103) that distributes mobile communication terminal 10 to utilize.
Described mobile communication terminal 10 detects positive direction Traffic Channel (F-TCH:Forward TrafficChannel) and then transmits preamble bit (Preamble) (seeing step S104) with the contrary direction Traffic Channel (R-TCH:Reverse Traffic Channel) of being distributed, described base station 20 detects preamble bit (seeing step S105), and receiving certification signal (ACK Order) is sent to mobile communication terminal 10 (seeing step S106).
Described mobile communication terminal 10 sends invalid signal of communication (seeing step S107) with the contrary direction channel that distributes, and forms service negotiation (seeing step S108) afterwards between mobile communication terminal 10 and base station 20.If the success of described service negotiation, then the tinkle of bells (Ring) sounds and the other user (Land) 30 is known have phone to make (seeing step S109), and base station 20 sends ring-back tone (Ring BACK Tone) (seeing step S110) to the other side simultaneously.
(see step S111) when described user 30 receives phone, base station 20 disconnects ring-back tone (seeing step S112) connection conversation (seeing step S113) for mobile communication terminal 10.At this moment, any one step is failed and all can't be conversed in a plurality of steps before the described step S113 that mobile communication terminal 10 and user 30 begin to converse.
The existing technology that redials is that 10 pairs of short messages that sent of mobile communication terminal are not when having replying of base station 20, the channel allocation short message that does not have base station 20, or mobile communication terminal 10 is not received the channel allocation short message that base station 20 sends, or receive that channel allocation is judged as connection failure when interrupting because having lost the positive direction signal before, redials from mobile communication terminal 10.That is when, in Access status, losing base station 20 signals or attempt to carry out call failure and be fit to redial when not receiving channel allocation to contrary direction addressing channel.
Described redialing as shown in Figure 1 can attempt to redial when step S103 fails, but after distributing the channel that mobile communication terminals 10 will utilize from base station 20, to when final execution in step S113 can the bid failure, can't carry out redialing operation.
In existing method, if under the situation that the calling that takes place after the channel allocation disconnects, call lose (Call Lost) situation has taken place in the General Notifications user, end call, again turn back to initial step (Mobile Station Initialization), when if the user wants to continue to attempt to converse, turn back to the repeating step of dialing again.
But, according to existing method, obtain channel allocation after, in carrying out call connection process, cause call interruption or can not redial when failing to carry out the call treatment step owing to wireless environment signal attenuation adverse circumstances such as (Fading).This is equivalent to not satisfy fully under the state of mobile communication terminal 10 user's communication demands, is not only redialing with being connected success of contrary direction addressing channel.Calling out connection failure in the later process of described step S103 only is to attempt to call out connection failure mobile communication terminal 10 users' position.
Before described mobile communication terminal 10 users converse through described step S113, no matter in any step, call out connection failure and be the calling connection failure, so under the high situation of possibility that the user calls again, exist mobile communication terminal 10 users to redial signal and inconvenience that needs dial again.

Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 2 is the flow chart that redials order of mobile communication system among the present invention, the flow chart that redial order of Fig. 3 for going offline when the channel allocation of mobile communication system among the present invention, Fig. 4 is for redialing the flow chart of order when the channel allocation of mobile communication system goes offline in addition among the present invention.Wherein, for carrying out said function with part shown in Figure 1 among Fig. 2 and Fig. 3 and Fig. 4, give same symbol and omit its detailed description.
At first, in the mobile communication terminal 10 of the present invention, redial on the call-handling capability, increased and considered to take place the following algorithm that redials when requiring incident in generality.
Incident 1 detects after channel allocation, the invalid signal of communication of the F-FCH that sends of the base station that obtains in the fixed benchmark of mobile communication terminal 10, fail successfully (step S104 failure) and cause call failure or decay (Fading) etc. and situation when causing signal interruption by wireless signal.
Incident 2 detects, the base station receives and sends to the reverse preamble bit that mobile communication terminal 10 distributes the reverse Traffic Channel that obtains, mobile communication terminal 10 sends confirmation of receipt signal (ACK order), in the process (step S106) of mobile communication terminal 10 these signals of reception, the collection of letters is failed in certain benchmark or wireless signal is decayed and the signal interruption of generation.After this, obtain base station signal, enter the process of redialing through initialization step.
Incident 3 detects, in the service negotiation procedures (step S108) of mobile communication terminal 10 and base station, because of consulting the signal interruption that the decay of failure or wireless signal takes place.After this, obtain base station signal, enter the process of redialing through initialization step.
Incident 4 monitoring also detect, receive ring-back tone at mobile communication terminal 10, whether the other side receives calls under the state of dont answer in the wait process, have phone under the state that mobile communication terminal 10 users or the other side or base station do not have to interrupt to connect the signal interruption that reason such as wireless signal decay causes.After this, obtain base station signal, enter the process of redialing through initialization step.
During generation incident 1, the state of mobile communication terminal 10 is in Access status (access state), so continue to catch existing base station signal to redial process.
Generation incident 2～4th, the channel allocation that the state of mobile communication terminal 10 obtains under Access status is utilized assigned channel, under the situation of the state transitions of communications status, the situation of bid connection failure.When the situation as incident 2～4 takes place, mobile communication terminal 10 is according to call treatment regulations (situation of IS-2000), begins to finish init state and obtains the base station from system validation (determina-tion) state of first sneak condition (sub-state) of init state.After the initialization,, set automatic re-dialing function, then attempted to redial according to automatic re-dialing function if mobile communication terminal 10 has obtained the base station.Redial and to make and a last number that number is identical, also can dial another number of prior appointment.Can specify in advance in addition and redial number of times or time, attempt to redial the time interval.
Fig. 2 is for explanation comprises the content that detects the conversation connection failure in the communications status of the present invention, redials the flow chart of process, and Fig. 2 is an example of synchronous mode mobile communication system, and is also different according to its content of mode of each mobile communication system.
As shown in Figure 2, after detecting the user and redialing, transmit institute's sent SMS message (seeing step S200) with reverse addressing channel, whether judgement obtains channel allocation (seeing step S201) from the base station in benchmark, when not obtaining channel allocation, get back to init state and redial (seeing the A step).
When obtaining described channel allocation, after obtaining channel allocation from the base station, in the forward traffic channel of being distributed, judge whether to receive invalid signal of communication (seeing step S202), if mobile communication terminal 10 fails to detect the invalid signal of communication in base station, then get back to init state and redial (seeing the B step).
When detecting described invalid signal of communication, detect the forward signal of communication of mobile communication terminal 10, to distributing the reverse Traffic Channel that obtains to transmit preamble bit (seeing step S203), whether judgement obtains base station confirmation of receipt signal (ACK) (seeing step S204) from the base station in benchmark, obtain base station confirmation of receipt signal (ACK) if in benchmark, fail from the base station, redial (seeing the B step) after then getting back to init state.
When receiving described base station confirmation of receipt signal (ACK), mobile communication terminal 10 carries out service negotiation (seeing step S205) with the base station, judge service negotiation whether successfully (seeing step S206), service negotiation failure or lossing signal and connect when interrupting redial (seeing the B step) after getting back to init state.
During the success of described service negotiation, the other side's the tinkle of bells sounds and the user that puts through phone can be sounded ring-back tone (seeing step S207).At this, described ring-back tone one sound, then start the timer 1 (seeing step S208) that does not show among the figure, timer 1 is after the tinkle of bells fully sounds, mobile communication terminal 10 or recipient user 30 that phone is not put through phone side are hung up, but when hanging up, no longer to redial in order judging, and to possess in the timer of mobile communication terminal 10 inside according to user's setting (set point is 1) because of other reason.
Under the state that described ring-back tone sounds, whether monitoring is because of wireless signal decay causing phone interruption (seeing step S209), the side of dialing or the side of answering are not hung up but when hanging up because of signal attenuation, judge that the timer that started 1 is whether greater than initial set value stored 1 (threshold1) (seeing step S210) in advance.At this, set point 1 can or can be set at appropriate value by mobile communication terminal 10 developers by user's setting in advance.
When described judged result timer 1 is bigger than set point 1, replacement timer 1 (seeing step S211), and ignore the ring-back tone that repeatedly sounds, because of the state that does not receive calls as yet, so the probability that phone connects is little, the caller is reluctant the big and terminated call (seeing step S212) of the possibility that redials.At this, described timer 1 is for not making mobile communication terminal 10 redial the timer that imports.
Described under the state that ring-back tone continue to ring, because of in wireless signal decay lossing signal, the S209 step of hanging up the telephone, the other side did not pick up a receiver to receive calls and then begins conversation (seeing step S213) when the monitored results phone was hung up in monitoring.
Described judged result timer 1 was than set point 1 hour, and replacement timer 1 (seeing step S214) moves to the B step that redials.At this, in the middle of step S200～step S214, when losing forward signal, also finish redialing as shown in Figure 2 by initialization step.
As shown in Figure 4, step S202 for described calling connection failure, S204, S206, S214 and by attempting send to call out (step S200) till successfully send calling (step S213) step, mobile communication terminal 10 is lost base station signal and is called out the situation of connection failure in the meantime, is necessary that the information stores that will redial (sees step S220) in the internal memory of mobile communication terminal 10.
When carrying out described step S202～S214, to start to receive and redial timer 2 (seeing step S221) and inform that the user is waiting for and redial (seeing step S222), mobile communication terminal 10 regains base station signal, if actually attempt to redial required time when oversize, can remove redialing requirement.
According to described step S202, S204, S206, the detected calling connection failure of S214, because be that state at mobile communication terminal 10 takes place in communications status, if so during synchronous mode CDMA, then according to the IS-2000 regulations by initialization step (seeing step S223), catch base station signal (seeing step S224).
Under the state that obtains base station signal, will whether be performed (seeing step S225) by a plurality of condition judgment automatic re-dialing functions.Comprising, attempt in the early stage to call out connection failure and cause redial necessary item and will be stored in the middle of the internal memory, inform that the user is after wait is attempted to redial, whenever as long as the user assigns mandatum cassatorium and then cancels the second condition that attempting in the internal memory that is stored in mobile communication terminal 10 redials wait, the first condition and the 3rd condition (the redialing function user sets ON and Req_Redial=True) that whether continue to be activated with the setting of after obtaining base station signal, judging redialing function, after attempting to redial, reception judges whether the 5th overtime condition (Timer2＜Th2), judge whether to exceed the 4th condition of attempting to redial number of times (＜M), the M of described the 4th condition attempts to redial the value that number of times user input in advance or mobile communication terminal 10 developers set preservation with maximum possible.
When carrying out described redialing, inform that the user attempts to redial (seeing step S226) and attempt to dial again (seeing step S227).At this, for statistics redials number of times replacement timer 2 (seeing step S228).
If attempt described redial then judge redial whether success (seeing step S229), under case of successful initialization with redial relevant parameter (the seeing step S230) words (seeing step S231) that work of going forward side by side.Under the described situation that redials failure, increase and attempt to redial number of times (seeing step S232), re-execute A and B step according to the state of mobile communication terminal 10.
Judging described redialing among the whether possible step S225, if could redial initialization with redial relevant parameter (seeing step S233), inform customer call failure (Call Fail) (seeing step S234) and wait (seeing step S235) under idle (idle) state.
As shown in Figure 3, in described benchmark, judge whether to obtain the step S201 of channel allocation from benchmark, redialing in the internal memory that stores mobile communication terminal 10 into of will being necessary under the situation that does not obtain channel allocation (seen step S240), owing to be the connection failure in the Access status, just get back to idle (idle) state (seeing step S241) without initial condition mobile communication terminal 10, judge catching under the state of present reference signal whether redialing function to be set at and open (ON) and whether be necessary to redial (seeing step S242).In this setting, attempt in the early stage to call out connection failure and cause redial necessary item and will be stored in the middle of the internal memory, inform that the user is after wait is attempted to redial, whenever as long as the user assigns mandatum cassatorium and then cancels the second condition that attempting in the internal memory that is stored in mobile communication terminal 10 redials wait, with first condition and the 3rd condition (the redialing function user sets ON and Req_Redial=True) whether the setting of judging redialing function after obtaining base station signal continues to be activated, judge whether to exceed the 4th condition of attempting to redial number of times (＜M).
When carrying out described redialing, inform that the user is attempting to redial (seeing step S243) and attempting to redial (seeing step S244).If attempt described redial then judge redial whether success (seeing step S245), if success then initialization with redial relevant parameter (the seeing step S246) words (seeing step S247) that work of going forward side by side.
Describedly redial when failure and increase and attempt to redial number of times (seeing step S248), re-execute A or B according to the state of mobile communication terminal 10.
In the step S 242 that judges whether to redial, if could redial initialization with redial relevant parameter (seeing step S249), inform customer call failure (Call Fail) (seeing step S250) and wait (seeing step S251) under idle (idle) state.
The present invention is when being used for calling out the way phone of Connection Step disconnecting between mobile communication terminal 10 and base station as mentioned above, knows the reason of calling out connection failure to a certain extent.
1) the calling connection failure of considering communications status redials and is, benchmark redial the failure that algorithm has only been considered the initial stage visit, in contrast, the state of the mobile communication terminal among the present invention 10 enters into the calling that takes place behind the communications status and disconnects and also according to circumstances may redial.For example, the side of calling or recipient or base station are not initiatively to disconnect connecting under the state of hearing ring-back tone momently, and the reason identical with the signal attenuation (Fading) between radio zone disconnects when connecting and can redial as far as possible.The calling that can't regard the side of calling or recipient in this case as connects and to disconnect, so the present invention is for solving mobile communication terminal 10 users' conversation purpose, and mobile communication terminal can redial automatically.
2) timer 1 is heard behind the ring-back tone through after the long time, because the reason identical with signal attenuation connect when disconnecting, and the possibility height of the situation that the idea of not answering the call in the side of answering the call maybe can not connect, so the possibility that the user no longer redials is also very big.In this case timer 1 is possessed in mobile communication terminal 10, fully understand and not attempt to redial when phone disconnects under the state of the meaning that does not receive calls.
3) timer 2 is that request redials in wait, and mobile communication terminal 10 is carried out initialization steps, obtains base station signal and need pass through when long-time to actual redialing, and puts through phone side and can forget attempting to redial.In this case timer 2 is possessed in mobile communication terminal, redialing operation when attempting to redial the back to the actual overlong time that resends can be cancelled automatically.
Making a phone call with same number or another number when 4) redialing is that same number that phone connects was put through phone or the user puts through phone with another number that configures in advance with attempting in the past when attempting to redial.
Present embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
