Embodiment
Basic thought of the present invention is: for the situation that has macro base station and private cell signal simultaneously, when the signal quality of private cell reached default access thresholding, portable terminal promptly inserted the private cell that allows its access; Further, when the signal quality of private cell is lower than defaultly when withdrawing from thresholding, portable terminal promptly switches to other private cell or the macro base station that allows this portable terminal to insert.
Need to prove that described access thresholding, to withdraw from thresholding be that these two threshold values can come to be provided with in advance according to the restituted signal ability of private cell for the private cell of determining to insert maybe needs the private cell that withdraws from portable terminal.
Among the present invention, when initial access private cell and portable terminal were from macro base station access private cell when portable terminal started, it was basic identical to insert handling process.The handling process that concrete portable terminal inserts private cell comprises:
The access thresholding of private cell signal is set, and, portable terminal will allow each private cell information of self inserting, and exist the macro base station information of signal covering overlapping area to be recorded in the information list, and will exist the macro base station information of signal covering overlapping area to be sent to corresponding private cell with private cell with each private cell; Portable terminal is searched the private cell that whether exists self to insert, during private cell that existence can insert, and the signal of this private cell of periodic scan, and obtain the current signal quality of this private cell; If when the signal quality of private cell reaches set access thresholding, then insert this private cell; Otherwise, continue the signal of this private cell is carried out periodic scan.
In addition, portable terminal is after inserting private cell, can lastest imformation the information of record in the tabulation, and preserve private cell information Unrecorded, that self can insert, and have other private cells and the macro base station information of signal covering overlapping area with the private cell of current access.
Above-mentioned for inserting the processing procedure of private cell, so, behind the access private cell, the handling process that switches to another private cell or macro base station from the private cell that has inserted comprises:
The thresholding that withdraws from of private cell signal is set, and, the signal of the private cell that mobile terminal period scanning is inserted self, and obtain the current signal quality of this private cell; Portable terminal judges whether the signal quality of the private cell that self inserts is lower than this and withdraws from thresholding, if being lower than this withdraws from thresholding, then withdraws from this private cell; Otherwise, the signal of the continuation private cell that periodic scan inserted.
Wherein, the concrete private cell that withdraws from current access, the step that switches to another private cell or macro base station comprise: portable terminal judges in the local information list whether have switchable private cell or macro base station information, if exist, then portable terminal utilizes the switchable private cell of information scanning or the macro base station signal of record in the self information tabulation; Otherwise portable terminal utilizes the neighboring broadcast messages of private cell to scan switchable private cell or macro base station information; After scanning switchable private cell or macro base station signal, portable terminal withdraws from the private cell of current access, switches to switchable another private cell or the macro base station that scan.
Insert the access procedure of private cell based on above-mentioned portable terminal, and the process that from the private cell that is inserted, withdraws from and switch to another private cell or macro base station, portable terminal is inserted private cell and be described in further detail below in conjunction with the drawings and specific embodiments from the concrete processing procedure that private cell switches to macro base station or another private cell.
Present embodiment switches to example with portable terminal between private cell and macro base station, illustrate that portable terminal preferentially inserts the realization flow of its private cell that can insert, with reference to Fig. 2 A, show the present invention and switch to the realization flow of private cell from macro base station, concrete steps are as follows:
Wherein, described access thresholding and withdraw from thresholding and can set in advance according to the restituted signal ability of private cell.
Portable terminal is preserved the information of above-mentioned private cell and macro base station in advance, so as portable terminal macro base station and private cell, and private cell and private cell between switch.
Here, the private cell information spinner will comprise: frequency, preamble index (Preamble index), private cell identification number (FBSID) etc.; Exist the macro base station information spinner of signal covering overlapping area to comprise with private cell: frequency, Preamble index, macro base station identification number (MBSID) etc.
Need to prove that the information of above-mentioned private cell and macro base station can also can be obtained by following two approach in advance by manually writing portable terminal:
A, portable terminal by himself place private cell and macro base station, and private cell and private cell between handoff procedure upgrades the information of private cell and macro base station automatically, that is: switch back modification or additional each private cell information that is kept at the permission access on the portable terminal and have the information of all macro base stations of signal covering overlapping area automatically with each private cell; Simultaneously, can there be this private cell in portable terminal all macro base station information of signal covering overlapping area to be sent to this private cell.
B, when portable terminal inserts private cell first, private cell can be notified to portable terminal with the information of this macro base station of obtaining by approach A.
Two kinds of approach of above-mentioned A, B can obtain the relevant information of private cell and macro base station by the handoff procedure that the back will be introduced, but no matter which kind of approach to obtain these information by, all the private cell that obtains and the relevant information of macro base station can be deposited in the information list, so that recalls information during operations such as portable terminal is searched, switching.
In this step, after portable terminal starts, if do not find the private cell that can insert, but find other base stations, as macro base station, then the height of basis signal quality selects a best base station of signal quality to insert.Here, present embodiment is that example illustrates remaining flow process with portable terminal selection access macro base station.
Whether step 204 in the macro base station that the portable terminal judgement inserts self, deposits the private cell signal that it can insert, if exist, then execution in step 205; Otherwise, finish this switching flow.
In this step, portable terminal calls the private cell information that inserts of self storage and has the macro base station information of signal covering overlapping area with private cell, judges the private cell signal whether self exists this portable terminal to insert in the macro base station that advances into; If there is no this portable terminal private cell that can insert then finishes this switching flow.
Here, when portable terminal is judged the private cell signal that existence can insert self in the macro base station that self enters, the start-up period scan mechanism, signal to private cell carries out periodic scan, to scan the private cell signal that this portable terminal can insert and the signal quality of corresponding private cell.Wherein, can be provided with according to actual conditions cycle of mobile scanning terminal, as information such as signal coverage areas size according to private cell.
This intermittent scanning mechanism comprises two kinds of mode of operations:
A, portable terminal automatic scan: trigger at the periodic scan that can insert private cell automatically.
B, auxiliary triggering scanning: the user is by ejecting the mode of dialog box on mobile terminal screen, whether the prompting user switches on the private cell, if the user provides affirmative acknowledgement (ACK), then triggers the periodic scan at this private cell; If the user provides negative acknowledge or do not answer, then do not trigger periodic scan at this private cell.Here, can periodically prompting function be set, that is: periodically eject dialog box, and whether switch on the current private cell that scans by voice prompting mode prompting user at portable terminal.
Portable terminal can be chosen the mode of operation that corresponds to actual needs arbitrarily.Need to prove whether the prompting of ejecting enters the dialog box of private cell on the screen of portable terminal, also can increase sound prompt function, further to cause user's attention.
When portable terminal finds the private cell that can insert, obtain the signal quality of this private cell that can insert and this signal quality is judged, judge whether the signal quality of the private cell that this can insert reaches the access thresholding.
Here, can be with reference to Fig. 3, the signal quality that shows private cell of the present invention with insert thresholding and withdraw from the relation of thresholding.Among Fig. 3, curve is the signal quality trend over time of private cell, and on behalf of the current signal quality of private cell, this curve reach the access thresholding with the intersection point F that inserts thresholding.
At this moment,, then insert this private cell, and needn't consider to exist other signal of base station quality in signal overlap zone, as macro base station etc. with this private cell as long as the signal quality of the portable terminal private cell that can insert arrives described access thresholding.
Here, during switching, the mode of operation of portable terminal comprises: idle pulley and enable mode.Under these two kinds of mode of operations, the main flow process that portable terminal switches between macro base station and private cell is identical, and its difference can be with reference to following analysis:
Switching under I, the idle pulley
For the portable terminal under the private cell, reach the access thresholding if under idle pulley, scan the signal quality of the private cell that can insert, then this communications of Mobile Terminals position is updated to the paging group at this private cell place, and no matter the signal quality of other base station such as macro base station etc.
Switching under II, the enable mode
For the portable terminal under the private cell, reach the access thresholding if under idle pulley, scan the signal quality of the private cell that can insert, then this portable terminal is except being updated to self communication position the paging group at this private cell place, this portable terminal also will self ongoing communication service is related information etc., data as transmission, switch in the lump on this private cell, and preserve the private cell information that to insert and have the macro base station information of signal covering overlapping area with this private cell.
Need to prove, portable terminal is from the process of macro base station switching and access private cell, if the relevant information of this private cell and macro base station is not recorded in the information list of portable terminal, then the relevant information of related private cell of this switching and access service and macro base station need record in the corresponding information tabulation, to upgrade this information list.The relevant information of this private cell and macro base station mainly comprises: the private cell information that portable terminal can insert, and have other base station informations of signal covering overlapping area etc. with corresponding private cell.
In addition, be linked into other macro base station when portable terminal after, can carry out the switching of macro base station with reference to above-mentioned switching flow to private cell.
Portable terminal inserts after the private cell, continues the signal of private cell is carried out periodic scan, if scan the signal quality variation of the private cell that is inserted, withdraws from thresholding if reach, and portable terminal is then initiated the switching flow of private cell to macro base station.With reference to Fig. 2 B, show portable terminal of the present invention and switch to the realization flow of macro base station from private cell, concrete steps are as follows:
Step B201, the signal of the private cell that mobile terminal period scanning is inserted self, and obtain the current signal quality of this private cell;
Step B202, portable terminal judge whether the signal quality of the private cell of himself current access is lower than and withdraw from thresholding, if, execution in step B203 then; Otherwise, return execution in step B201;
Here, as shown in Figure 3, curve is the signal quality trend over time of private cell, and on behalf of the current signal quality of private cell, this curve reach with the intersection point M that withdraws from thresholding and withdrawed from thresholding, if the signal quality variation of private cell just will withdraw from private cell.
Step B203, portable terminal judge self whether there is switchable macro base station information, if existence, then execution in step B204; Otherwise, execution in step B205;
If the existing switchable macro base station information spinner of portable terminal is recorded in the information list, this is because the private cell that portable terminal will get access to from insert, switch to process such as private cell usually and the relevant information of macro base station all store in the local information list, so as to search, recalls information during operation such as switching.
Step B204, portable terminal utilize the signal of the switchable macro base station of information scanning of record in the self information tabulation;
Portable terminal is the existing macro base station information of this private cell of search in the self information tabulation, and call switchable macro base station information, scans this macro base station signal.
The neighboring broadcast messages of private cell of utilizing step B205, portable terminal scans switchable macro base station signal;
Usually, there are the signal covering overlapping area in this switchable macro base station and this private cell.Private cell will be stored as neighboring broadcast messages with the macro base station information that self has the signal covering overlapping area usually, be convenient to search, call when switching.
Step B206, portable terminal switches to macro base station.
After scanning the signal of macro base station, just can carry out the switching from the private cell to the macro base station.At this moment, the signal quality of macro base station generally all is higher than the signal quality of private cell.
Such scheme has provided the switching flow between private cell and the macro base station, in the practical application, may there be two or more private cells in the macro base station, if the private cell that wherein exists two or more portable terminals to insert then can be initiated the switching between private cell and the private cell.In fact, switching flow between private cell and the private cell, and the switching flow basically identical between private cell and the macro base station, different only is: after withdrawing from from a private cell, what portable terminal inserted is another private cell that self can insert, but not macro base station.
Need to prove, if in the neighboring broadcast messages of the information list of portable terminal and private cell, all do not find the information of macro base station, if this moment, portable terminal was in state of activation, then may cause its communication disruption, but, portable terminal just can communicate after searching the signal of switchable macro base station once more.
Below in conjunction with Fig. 4, illustrate above-mentionedly to switch to private cell, and switch to the disposed of in its entirety flow process of macro base station that concrete steps are as follows from private cell from macro base station:
Step 401, after portable terminal 4c entered macro base station 4a, if there is the signal of the private cell 4b that portable terminal 4c can insert in the macro base station 4a zone, start-up period scan mechanism then periodically scanned the signal of this private cell 4b; If there is not the signal of the private cell 4b that portable terminal 4c can insert in the macro base station 4a zone, then needn't the start-up period scan mechanism, portable terminal 4c communicates business in macro base station 4a, finish this switching flow.
In Fig. 4, the intermittent scanning that the representative of small circle on the curve is performed, curve are then represented portable terminal performed intermittent scanning situation in this macro base station.
Step 402, the signal quality of the private cell 4b that scans reaches default access thresholding, and then portable terminal 4c switches to the private cell 4b from macro base station 4a, and 4b communicates by this private cell;
In this step, as long as the signal quality of private cell 4b reaches default access thresholding, portable terminal 4c promptly cuts this private cell 4b, and needn't consider the signal quality of macro base station 4a this moment.
Step 403, the signal quality of the private cell 4b that scans is lower than the default thresholding that withdraws from, and then portable terminal 4c switches to the macro base station 4a from private cell 4b, and 4a communicates by macro base station;
Step 404, portable terminal 4c leaves this macro base station 4a, then stops to carry out periodic scan.
Here, after portable terminal 4c leaves this macro base station 4a, can insert other base station, for example: other macro base stations or another private cell etc., perhaps, this portable terminal 4c may cause communication to suspend because of the base station that can not insert temporarily.But,, can communicate by letter once more as long as can scan signal of base station.
