According to the present invention, in BS 101 and RS 103,105,107,109, has the function that is used for topology learning and renewal.
Below, term " RS enters " is meant that a RS (fixedly RS and mobile RS) enters a sub-district for the first time.
Term " the RS intra-cell is changed " is meant that a RS (mobile RS) switches to another RS (or BS) in the same sub-district from the RS (or BS) in the sub-district.
Term " switching of RS minizone " is meant that a RS (mobile RS) switches to RS or the BS in another sub-district from a sub-district.
Term " RS leaves " is meant that a RS (fixedly RS and mobile RS) removes (not being to switch to another sub-district from a sub-district) from the sub-district.
Term " MS enters " is meant that a MS enters a sub-district for the first time.
Term " the MS intra-cell is changed " is meant that MS RS (or BS) in the sub-district switches to another RS (or BS) in the same sub-district.
Term " switching of MS minizone " is meant that a MS switches to another sub-district from a sub-district.
Term " MS leaves " is meant that a MS removes (not being to switch to another sub-district from a sub-district) from the sub-district.
The RS process of entering comprises initiating ranging process.In initiating ranging process, one enters RS and sends the initial ranging request.Four kinds of basic possible outcomes are arranged:
1). only BS can receive the initial ranging request, and BS becomes the access point that enters RS then.
2). only a neighbours RS can receive the initial ranging request, and this neighbours RS reports that to BS or his father RS this enters RS, and this neighbours RS becomes the access point (father RS) that enters RS then.
3). only a plurality of neighbours RS receive the initial ranging request.In this case, all neighbours RS that receive the signal with enough signal strength signal intensities report that to BS or his father RS this enters RS, and BS determines that from the set of neighbours RS this enters the father RS of RS then.
4) .BS and neighbours (one or more) RS receives the initial ranging request.Neighbours RS reports that to BS or his father RS this enters RS, and BS will carry out Route Selection then, to select entering the access point of RS by BS as this, still enters the access point (father RS) of RS by neighbours RS as this.
Enter in the process at RS, enter RS its identifying information is told to BS, to distinguish RS and MS.
In an embodiment of the invention, its identifying information is told realize by following method for entering RS: enter RS and will use new CDMA sign indicating number sequence to be used for initial ranging to his father RS or BS.Like this, can know soon that a RS is entering process.
In yet another embodiment of the present invention, its identifying information is told to his father RS or BS that the MAC message by following redetermination or expansion realizes for entering RS:
I) .RNG_REQ+RS identifying information;
Ii) .SBC_REQ+RS identifying information;
Iii) enter any other MAC message in the process at RS;
Iv) to the MAC message of the redetermination of BS notice.
Here, it is a RS that the identifying information of RS is indicated this station, rather than MS.Be associated is used for determining a specific RS to the unique appointed information of this identifying information and RS (for example the MAC Address of RS etc.).
In addition, this relevant parameter Final Report that enters RS is given in the process of BS for all father RS that enter RS, in the following information one or multinomial will be useful:
RS CDMA sign indicating number;
The RS MAC Address
Time migration;
Power measurement;
Frequency offset estimation.
Change process for the RS intra-cell, because RS is also in the sub-district, in other words, RS has experienced the above-mentioned process that enters, and has reported its identifying information, does not therefore need to report the identifying information of RS again.
For RS minizone handoff procedure (sub-district is gone in switching), it is similar that situation and above-mentioned RS enter process, need send initial ranging request and its identifying information of report, although can obtain some information from affiliated base station before the switching of this RS.
When having the next stage RS that belongs to RS at the corresponding levels to leave, these corresponding levels RS produces the message that an indication requires to change topology, and sends this message to its father RS or BS.
For example, when RS 107 left, RS 105 produced the message that an indication requires to change topology, and sent these message to its father RS 103, gave BS 101 by RS 103 with this message report.
Leave and comprise normally leaving and leave with improper.
Situation about normally leaving can be that the RS that leaves sends a leave group message to his father RS or BS.
Improper situation about leaving can be that for example, in periodic range finding or periodic information exchange, RS at the corresponding levels does not receive the information of its next stage RS within a time threshold.
Switch (switch and the sub-district) for the RS minizone, situation is normally left similarly with aforesaid, and also needs to carry out topological change.
In addition, RS also reports the information about MS that is detected to BS or his father RS, is connected to which RS with instruct MS.This report by MS enter, the MS intra-cell is changed, switch the MS minizone, MS leaves etc. triggers.
In an embodiment of the invention, MS enters process and MS under the situation that does not have RS to enter process identical.
Switch (sub-district is gone in switching) for the MS minizone, it is similar that situation and above-mentioned MS enter process.
And for the MS intra-cell change, the MS minizone switch (switch and the sub-district), and MS leave because MS has experienced the process of entering, so situation is fairly simple, and similar with the corresponding process of above-mentioned RS.
Should be appreciated that the generation of all above-mentioned incidents (comprise that RS enters, the RS intra-cell is changed, switch the RS minizone, RS leaves, MS enters, the MS intra-cell is changed, switch the MS minizone, MS leaves) all can be notified to BS.
Aspect BS, at first,, set up the topology table of a sky at its initial phase.Can utilize the parameter of some existing RS, manually dispose this topology table by the operator.
Topology table records the connection status of the RS in the sub-district.
For example, for sub-district shown in Figure 1,, can draw RS 107 and be connected to RS 105 according to topology table; RS 105 is connected to RS 103; RS 103 is connected to BS 101.
In addition, also having is the MS attached table that topology table is replenished part, and indication is connected to the situation of the MS of RS or BS.This MS attached table can be arranged in RS, BS or these two.Topology table and MS attached table can be integrated in the table, as two logical gates, can also be two independent parts, depend on specific implementation.
As described above, upgrade can be by following event-driven for topology table:
I) .RS enters;
Ii) .RS leaves (comprise normally leaving with improper and leave);
Iii) the .RS intra-cell is changed;
Iv) (comprise switching the sub-district and switching and the sub-district) switched in the .RS minizone;
V). system optimization.
And as described above, the MS attached table upgrades can be by following event-driven:
