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 both had been 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 the selection course of association identification device of mobile phone and 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 all concentrator markers 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 both had been an 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 left identifying cells A, mobile phone should be able to be made correct judgement 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, searches the concentrator marker state: residing state when mobile phone is not found any correlated identities device;
2, detecting identifying cells switching state: mobile phone has been found the correlated identities device, and determines that it is the later state of association identification device.
(be that concentrator marker is gone out the identification information fixed time broadcast of being stored with broadcast mode below; The mobile phone receiving function that gives information) mode is that example is set forth embodiment illustrated in fig. 1.
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, this number are descending number. |
| Concentrator marker ESN | 8 16 system numbers | The equipment electronic serial number, ESN of concentrator marker, non-NULL |
| |

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, this number whole world is unique) of concentrator marker.Mobile phone is at the state of step 1, essence is to be in the concentrator marker state of seeking, the association identification device ESN number of preserving in the mobile phone this moment is empty (NULL), like this, mobile phone is when receiving the broadcast frame of concentrator marker, just according to wherein identification information, carry out number analysis, whether be the correlated identities device of mobile phone to judge this concentrator marker.Therefore judge in step 2 whether this concentrator marker is the correlated identities device, if not, then mobile phone keeps the state of searching concentrator marker, returns the search that step 1 continues next round; Judge that whether this concentrator marker is that the analyzing and processing process of correlated identities device mainly is to carry out number analysis, promptly searches stored calls traversal lists in the mobile phone according to the Electronic Serial Number in the broadcast message (ESN); Judge whether to exist the calling transfer destination Mobile Station International ISDN Number of the Electronic Serial Number correspondence of this concentrator marker, when mobile phone is learnt the calling transfer destination Mobile Station International ISDN Number of the Electronic Serial Number correspondence of corresponding concentrator marker in the broadcast message that existence handling through step 2, just think and searched its correlated identities device, and determine that in step 3 this correlated identities device be its association identification device (is about to the ESN that association identification device ESN in the mobile phone is set to this correlated identities device, and the broadcast frame time of initialization wait association identification device).After having determined the association identification device, carry out the automatic setting of calling transfer in step 3, stop the analyzing and processing of broadcast that the different identification device is sent simultaneously, promptly no longer get in touch with other concentrator marker (comprising the correlated identities device).Then mobile phone is shaken hands at step 4 and concentrator marker and is got in touch, and on this is shaken hands and intergrates with practice is to judge whether that by mobile phone the broadcast frame that can receive the association identification device realizes; 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, at this state, and the association identification device ESN number that the association identification device ESN number of preserving in the mobile phone is determined for 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 any concentrator marker; If identical, then carry out relevant treatment, processing procedure mainly is the broadcast frame time that the association identification device is waited in initialization.Mobile phone judges whether to leave the association identification device in step 5, promptly judge to shake hands whether interrupt, the foundation that judging shakes hands interrupts is that (this time value is called as switching sensitivity value W to mobile phone at certain hour, can be provided with, when not being provided with, adopting default value, can be skilful second as default value) in can not receive the broadcast frame of association identification device.If mobile phone has left concentrator marker, then cancel original calling transfer setting, enter search association identification device state, change the concentrator marker search that step 1 continues next round, otherwise continue the operation of step 4.
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 be received at first that correlated identities device of signal 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, the realization of step 5 is exactly after mobile phone is waited for certain hour (switching sensitivity value W), does not still receive the broadcast frame of its association identification device, promptly wait for 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 have carried 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 concentrator marker 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.After mobile phone was confirmed to have left its association identification sub-district, mobile phone reenters searched association identification device state, and carries 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 search of association identification device and 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 identifying cells, 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 identifying cells 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 analyzing and 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 must think carried 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 purpose phone 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 mobile phone can alternately receive the broadcast frame of association identification device when mobile phone is in the zone of intersection of several identifying cells, and at this moment, handover operation repeatedly can appear in mobile phone, and promptly association identification sub-district sham cut is changed.Can solve this sham cut effectively and change phenomenon and the mechanism of waiting for the timing of association identification device broadcast frame is set.
In Fig. 4, what heavy line was represented to be connected is the association identification device at Fig. 2.Dotted line represents to receive the signal of dereferenced concentrator marker, but these signals all are filtered and lose.
