The scheme of the present invention is simply realized, the scheme can ensure that the mobile phone can exactly select the relevant marker, and the marking small zone can be exactly switched, and the performance and the stability of the call transferring operation of the mobile phone are improved.
Description
Technical field
The present invention relates to the selection and the association identification cell switching method of the association identification device in the mobile calls intelligence transfer process.
Background technology
For the intelligence that realizes mobile calls shifts, usually need be provided for identifying the landline telephone concentrator marker of the purpose landline telephone that mobile calls shifts, and the identifier that is provided for discerning the landline telephone concentrator marker, this identifier is built in mobile phone inside; The built-in identifier of mobile phone obtains the fixed telephone number that it the identified tabulation of the landline telephone concentrator marker storage that oneself searches, therefrom select suitable diverting call purpose landline telephone, send the setting that calling transfer is finished in the calling transfer instruction to the mobile network then.When realizing mobile calls intelligence forwarding function according to such scheme, there is such a case, possible mobile phone is in the intersection region of several identifying cells simultaneously, with reference to figure 2.Because mobile phone may be in the identifying cells intersection overlay area of several concentrator markers, will cause mobile phone can't correctly select the association identification device; Simultaneously when mobile phone when an identifying cells enters another identifying cells fast, the not cancellation of old calling transfer that may cause user's mobile phone to cancel, the new calling transfer that should be provided with is not provided with; Frequent association identification sub-district perhaps occurs and switch, make mobile calls intelligence forwarding function be difficult to stable the realization.Above-mentioned phenomenon mainly occurs in office such as the office building close quarters or in inhabitation close quarterses such as residential building, because the placement uncertainty of concentrator marker, and the identifying cells intersection that concentrator marker occurs covers phenomenon, thereby causes the association identification sub-district switching problem that mobile phone is striden identifying cells to the selection problem and the mobile phone of association identification device.The quality that the problems referred to above solve directly influences performance and stability that mobile calls intelligence shifts.
Summary of the invention
The object of the present invention is to provide a kind of selection of the association identification device based on broadcast mode and the changing method of association identification sub-district, use this method can improve performance and stability that mobile calls shifts.
For achieving the above object, the selection of the association identification device based on broadcast mode provided by the invention and the changing method of association identification sub-district comprise the steps:
Step 1: mobile phone Search Flags device, have the transfer phone list that it identifies in the broadcast frame of described concentrator marker, mobile phone is according to the order of receiving broadcast frame, judge in the transfer phone list of broadcast frame whether the calling transfer destination Mobile Station International ISDN Number is arranged, if have, the concentrator marker that sends this broadcast frame as the association identification device, is carried out the setting of calling transfer, no longer analyze follow-up broadcast frame simultaneously; If do not have, then continue to analyze the next broadcast frame of receiving;
Step 2: mobile phone is shaken hands at association identification sub-district and association identification device and is got in touch, whether successfully judge whether to leave the association identification sub-district by the contact of shaking hands in the given time simultaneously, if do not leave, the operation of repeating step 2, otherwise change step 1 and continue the new concentrator marker of search, to finish the switching of association identification sub-district.
In described step 1: mobile phone abandons not comprising the broadcast frame that shifts phone list and shifting the broadcast frame that does not comprise the calling transfer destination Mobile Station International ISDN Number in the phone list of being received.Mobile phone judges that whether comprising the calling transfer destination Mobile Station International ISDN Number in the traversal lists in the broadcast frame is to carry out intersection operation with the transfer masked list of preserving in this calling transfer destination Mobile Station International ISDN Number tabulation and the mobile phone to obtain, occur simultaneously for empty, then do not have the transfer destination number; It is not empty occuring simultaneously, and the number in then occuring simultaneously promptly can be used as the purpose telephone number that mobile calls shifts.
The described mobile phone of step 2 is shaken hands to get in touch by mobile phone at association identification sub-district and association identification device and is judged whether that the broadcast frame that can receive the association identification device realizes.
Because the present invention judges by the transfer phone list in the broadcast frame of the concentrator marker received whether the calling transfer destination Mobile Station International ISDN Number is arranged in this table, if have, with this concentrator marker as the association identification device, carry out the setting of calling transfer, stop the processing of broadcast frame that other concentrator marker is sent simultaneously, like this, when mobile phone enters into the intersection region of a plurality of concentrator marker identifying cells, can be at first with send have transfer destination number broadcast frame concentrator marker as the association identification device, stop the analyzing and processing of broadcast frame that other concentrator marker is sent simultaneously, i.e. termination is got in touch with other correlated identities device, therefore adopts method of the present invention can effectively finish the selection of association identification device; When switching in the association identification sub-district, only when mobile phone leaves the association identification sub-district, just finish the switching of association identification sub-district by searching for new association identification device, as seen, the present invention not only realizes simply, and can guarantee immediately, correctly to carry out the selection of association identification device and the switching of association identification sub-district, effectively avoid not switching, sham cut changes phenomenon, therefore uses this method can improve performance and stability that mobile calls shifts.

Embodiment
The method of the invention is used to solve when mobile phone appears at the identifying cells intersection overlay area of several concentrator markers, the association identification sub-district switching problem that mobile phone is striden identifying cells to the selection problem and the mobile phone of association identification device.The method of the invention relates generally to following notion:
1, identifying cells, the signal coverage areas of a concentrator marker, in this zone, the identification information that mobile phone can obtain in the concentrator marker to be stored;
2, correlated identities device, if the identification information of storing according to concentrator marker, through behind the number analysis of mobile phone, can access the destination Mobile Station International ISDN Number tabulation that mobile calls shifts that is used for of non-NULL, then this destination Mobile Station International ISDN Number tabulation is the related telephone tabulation of mobile phone, this concentrator marker is the correlated identities device of mobile phone;
3, association identification device is to make the mobile phone that enters its identifying cells that the concentrator marker that calling transfer is provided with take place;
4, correlated identities sub-district, the identifying cells of the correlated identities device sign of mobile phone is the correlated identities sub-district of this mobile phone;
5, association identification sub-district, the identifying cells of the association identification device sign of mobile phone is the association identification sub-district of this mobile phone.
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the embodiment flow chart of the method for the invention.The described method of Fig. 1 has been described two related when mobile phone appears at the identifying cells intersection overlay area of several concentrator markers processes, the one, the selection course of association identification device, the 2nd, the handoff procedure of association identification sub-district.
Association identification device selection course is with reference to figure 2.As shown in Figure 2, directly enter the intersection region of several identifying cells when mobile phone after, mobile phone should select suitable concentrator marker as its association identification device, the calling transfer setting of being correlated with simultaneously, and the message frame of concentrator marker filtered, filter out the message that belongs to the association identification device, and with this foundation as the switching of association identification sub-district, this process is association identification device selection course.
The association identification cell switch process is with reference to figure 3, as shown in Figure 3, after mobile phone leaves association identification sub-district A, mobile phone can be made correct judgement (foundation of judgement is to realize by the broadcast frame timing of waiting for the association identification device) to this, the calling transfer setting of being done when advancing into this identifying cells earlier with cancellation reenters the concentrator marker state of searching.After mobile phone enters identifying cells B, to receive the message frame of concentrator marker B, at this moment, mobile phone will carry out the transfer destination number analysis, and determine whether concentrator marker B can be as the association identification device of mobile phone, and this process is the association identification cell switch process.
In method shown in Figure 1, the mobile phone that is in above-mentioned two processes has two typicalnesses:
1, searching the concentrator marker state, is mobile phone residing state when not finding any association identification device;
2, detecting association identification sub-district switching state is the state that the association identification device was found and selected to mobile phone;
(be the concentrator marker broadcast capability that gives information, the identification information fixed time broadcast of being stored is gone out with broadcast mode below; The mobile phone receiving function that gives information) sets forth embodiment illustrated in fig. 1 for example.
Mobile phone at first enters the state of Search Flags device, at step 1 Search Flags device.The described concentrator marker broadcast capability that gives information is gone out the identification information fixed time broadcast of being stored.In this example, the identification information frame of concentrator marker broadcasting is with reference to following table:
| Information element | Length (byte) | Describe |
| MsgCode | 4 (longs) | Message code shifts phone list message for broadcasting herein, and this number is descending number, is defined as even numbers. |
| Concentrator marker ESN | 8 16 system numbers | The Equipment Serial Number sign indicating number of concentrator marker, non-NULL |
| |
4 | |
| Transfer |
4 | |
| The transfer destination list of numbers | 0～128K |
The mobile phone receiving function that gives information, this of mobile phone function can realize by built-in identifier in mobile phone.In the identification information of concentrator marker broadcasting, all must carry the ESN (Electronic Serial Number, electronic serial number) of concentrator marker, the ESN number that this number needs to guarantee cross one another those concentrator markers of identifying cells does not at least repeat.Mobile phone is at the state of step 1, essence is to be in the state of seeking concentrator marker, the concentrator marker ESN number of preserving in the mobile phone this moment is empty (NULL), like this, during the identification information of mobile phone in receiving the broadcast frame of concentrator marker, whether just can carry out number analysis, be the correlated identities device of mobile phone to judge this concentrator marker.If mobile phone searches concentrator marker, promptly enter into identifying cells, the list of numbers that then in the broadcast frame of the concentrator marker that step 2 judgement searches, whether comprises its identification telephone, promptly shift phone list, if do not comprise, can not judge then whether this concentrator marker is the correlated identities device, therefore abandon the broadcast frame of this concentrator marker in step 4, mobile phone keeps the state of searching concentrator marker, changes step 1 and carries out the search of next round; If comprise the transfer phone list in the broadcast frame, then mobile phone continues to judge the transfer destination number whether own needs are arranged in the transfer phone list in step 3 according to above-mentioned information, if do not have, still execution in step 4 abandons the broadcast frame of this concentrator marker, mobile phone keeps the state of searching concentrator marker, changes step 1 and carries out the search of next round concentrator marker; Otherwise, when mobile phone is learnt the calling transfer destination Mobile Station International ISDN Number that has oneself to need in the broadcast frame of handling through above-mentioned steps 3, just think and searched its association identification device, step 5 determine this concentrator marker be the association identification device (promptly, upgrade association identification device ESN in the mobile phone), and carry out the automatic setting of calling transfer, the broadcast frame time of association identification device is waited in initialization, stop the analyzing and processing of broadcast frame that other concentrator marker is sent simultaneously, promptly no longer get in touch with other correlated identities device.Then mobile phone is shaken hands at step 6 and association identification device and is got in touch, and this contact of shaking hands judges whether to receive the broadcast frame realization of association identification device by mobile phone; This contact is equivalent to mobile phone and only does " spy sound " processing, promptly surveys the broadcast frame that whether can also receive its association identification device.The foundation of " spy sound " is according to concentrator marker ESN in the identification information that carries in the broadcast frame.This moment, mobile phone entered detecting association identification sub-district switching state, and at this state, the concentrator marker ESN number of preserving in the mobile phone is the association identification device ESN number of this mobile phone, and this number definitely can not be sky.Mobile phone will judge all in this broadcast frame whether the association identification device ESN of current preservation is identical, inequality in the concentrator marker ESN and this mobile phone, just abandons this frame when receiving the broadcast frame of concentrator marker; If identical, then carry out relevant treatment, and the broadcast frame time of association identification device is waited in initialization.Mobile phone judges whether to leave the association identification device in step 7, promptly judge to shake hands whether interrupt, if mobile phone has left the association identification device, then cancel original calling transfer setting, enter search condition, change the concentrator marker search that step 1 continues next round, continue to get in touch with shaking hands of association identification device otherwise change step 6.
From the above, in the embodiment shown in fig. 1, it is to finish by the mode of the formula of trying to be the first that the association identification device is selected, promptly may there be several correlated identities devices, can both be also selected by the number analysis of mobile phone, but mobile phone only selects to receive at first that correlated identities device of signal is as its association identification device.
After a mobile phone leaves its association identification sub-district, mobile phone will no longer be received the broadcast frame of this association identification device, and mobile phone judges by the wait timing to association identification device broadcast frame whether it has really left the association identification sub-district.In this example, (this time value is called as switching sensitivity value W when mobile phone wait certain hour exactly in the realization of step 7, can be provided with, this routine default value is 15 seconds) after, still do not receive the broadcast frame of its association identification device, i.e. wait is overtime, so, mobile phone just thinks that it has left its association identification sub-district.Because mobile phone can not receive that the frame of other concentrator marker judges whether to carry out the association identification sub-district and switches with it, because, mobile phone may be in the intersection region of several identifying cells, and alternately receives the broadcast frame of association identification device and other concentrator marker; Therefore, mobile phone judges according to the concentrator marker ESN in the broadcast frame whether this broadcast frame belongs to that the association identification device of mobile phone sends, if inequality in ESN in the broadcast frame and the mobile phone, then explanation is that other not related concentrator marker sends, therefore, abandon this broadcast frame and end process; If identical, illustrate that promptly this mobile phone can also receive the signal of association identification device, illustrate that mobile phone does not leave its association identification sub-district as yet, at this moment, the time of association identification device broadcast frame waited for initialization by mobile phone.So after mobile phone was confirmed to have left its association identification sub-district, mobile phone reenters searched the concentrator marker state, and carried out new association identification device and select to handle.Like this, determine that by the broadcast frame timing of waiting for the association identification device mobile phone leaves the association identification sub-district, and make mobile phone reenter association identification device selection mode, reach the purpose that switch the association identification sub-district with this.
Why mobile phone will abandon the broadcast frame that is not that association identification device to one's name sends, be because, may have a plurality of concentrator markers to send broadcast frame simultaneously, with reference to figure 4, the previous association identification sub-district of mobile phone B is B, owing to walk about, mobile phone has left its association identification sub-district B now, but it is still in identifying cells A and C, at this moment, the broadcast frame that mobile phone B receives is the broadcast frame that concentrator marker A and C send, and mobile phone B just must abandon this broadcast frame; Otherwise, the handoff failure that will cause the association identification sub-district, promptly can not judge, because the association identification sub-district B that walks about and left oneself, need being connected of disconnection and association identification device B, and cancel previous calling transfer and set, reenter own concentrator marker (as shown in Figure 4 concentrator marker A, the C) state on every side of searching.
In a word, even mobile phone is in the intersection region of several identifying cells, after as long as mobile phone has found the association identification device of oneself, just can not remove to seek other concentrator marker again, can not respond the various message that other concentrator marker is sent, till mobile phone has left its association identification sub-district yet.This has just solved in the office building, and during concentrator marker possibility very dense, the identifying cells intersection that is produced covers caused association identification sub-district handoff failure problem.
When using embodiment shown in Figure 1, require concentrator marker that the signal emission function only is provided, require mobile phone that signal receiving function (similar beeper) only is provided.Concentrator marker is broadcasted away the identification information of storage by the mode of fixed time broadcast, after mobile phone is received this broadcast singal, and the processing of being correlated with.
In the embodiment shown in fig. 1, the mechanism of waiting for the timing of association identification device broadcast frame being set, is in order to solve, and when mobile phone was in the intersection region of several identifying cells, the association identification sub-district sham cut that causes was changed phenomenon.If should mechanism, so, when the association identification device ESN that has preserved in concentrator marker ESN and this mobile phone in the mobile phone judgement broadcast frame is unequal, just think must carry out the association identification sub-district switch (otherwise, association identification sub-district handoff failure phenomenon can appear), when this is in the zone of intersection of several identifying cells at mobile phone, handover operation repeatedly can occur, cause mobile phone to shift and set the frequent operation of setting with cancellation.With Fig. 2 is example, in mobile phone is in the intersection region of two identifying cells A, B, mobile phone alternately receives the broadcast frame of two concentrator markers, wherein, a destination Mobile Station International ISDN Number that will shift is arranged among the A, do not have among the B, this will cause mobile phone constantly to shift setting and setting operation is shifted in cancellation, and this phenomenon will constitute " harassing and wrecking " to the mobile network.This when mobile phone is in the zone of intersection of several identifying cells, mobile phone can alternately receive the broadcast frame of association identification device and other concentrator markers, and at this moment, handover operation repeatedly can appear in mobile phone, and promptly association identification sub-district sham cut is changed.The mechanism of waiting for the timing of association identification device broadcast frame is set, can addresses this problem effectively.
