Description

Location updating method and system
Technical field
The present invention relates to the communication system technology, particularly location updating method and system.
Background technology
In communication system, can comprise countless sub-districts, these sub-districts are the elementary cells that constitute mobile communications network, corresponding base station, each sub-district, one or more sub-districts of one general configuration, a base station, the calling task in this sub-district is responsible in each sub-district.The call center calls out one calledly has a dual mode usually: if the position at called place is known by the call center, then directly carry out paging in the position at this called place; If the position at called place is not known by the call center, and it is called to guarantee that call arrives, and just must carry out the whole network paging.
Particularly, in gsm communication system, have a lot of sub-districts under the switch,,, then directly carry out paging in the sub-district at this terminal place if MSC knows the sub-district at this present place of terminal when mobile switching centre (MSC) when wanting calling terminal; If MSC does not know this location information of terminals, paging just need be carried out paging to all sub-districts under this MSC to this terminal again.
At above-mentioned two kinds of paging modes, actual promptly corresponding two kinds of position update modes:
One, terminal is all notified MSC to carry out the position and is upgraded when the gravity treatment of each sub-district, and MSC just can get final product a current sub-district of this terminal of a paging when paging.The advantage of this method is the paging range minimum, and it is minimum that paging takies interface-free resources! But shortcoming also clearly, and the size of message that upgrades the position exactly is too big, and signal resource consumption is big.
Two, terminal if the MSC at place does not change, is not just notified MSC when the gravity treatment of each sub-district, and MSC carries out paging to all sub-districts under this MSC and gets final product when paging.The advantage of this method is that the number of times that the position is upgraded can drop to minimum, the signal resource consumes least! But shortcoming is that paging range is too big, calls out the interface-free resources maximum that takies!
Shortcoming at above-mentioned two kinds of schemes, taked a kind of solution of compromise in the existing GSM network, introduced the notion of lane place, promptly, to be distinguished into one or more lane place for a short time under the MSC, comprised a plurality of sub-districts below each lane place, these lane place closely connect, but non-overlapping copies.Like this, when terminal changes in the position, for example during the gravity treatment of sub-district, whether the lane place of new sub-district changed judge that if the lane place of new sub-district is identical with the lane place at place, former sub-district, then MSC can not be notified in this sub-district gravity treatment; If the lane place of new sub-district is different with the lane place at place, former sub-district, then initiate more new technological process of position, the lane place variation has taken place in notice MSC.Under the update mode of this position, the mode of MSC call terminal should be mutually: when MSC paging terminal, paging is carried out in all sub-districts under the lane place at this terminal place.
But for above-mentioned location updating method, there is following problem: because the lane place is when dividing, closely link to each other but non-overlapping copies, therefore lane place L1 and lane place L2 are in the terminal that two lane place have a common boundary as shown in Figure 1, meeting moving around because of the position, the perhaps fluctuation of radio signal causes terminal when frequent re-selecting cell, can follow the frequent updating lane place, thereby cause a large amount of location area updating message, i.e. the position updating message.In view of this consideration, during Terminal Design, a threshold value is set, limit the mobile subscriber who is in the lane place intersection by this threshold value and carry out frequent location area updating location area updating.For example, it can be at signal strength difference that threshold value is set, and like this, the signal strength signal intensity of terminal sub-district in judging the reposition district and the difference in signal strength of current persistent district are during greater than described threshold value, just the executing location district upgrades, and is about to current persistent district gravity treatment and is this sub-district in the reposition district; Otherwise when promptly the difference in signal strength of the signal strength signal intensity of terminal sub-district in judging the reposition district and current persistent district was less than described threshold value, terminal was not carried out location area updating, promptly not with current persistent district gravity treatment this sub-district in this reposition district.
The restriction of above-mentioned passing threshold is in terminal that two lane place have a common boundary and carries out the mode of frequent location area updating and can bring following negative effect:
One, the terminal that is in the lane place boundary can not freely select to be suitable for most resident sub-district, particularly under all bad situation of the signal of each sub-district of intersection, terminal can not freely select the best sub-district of signal can make to mobile subscriber's paging success rate, and the call completing rate of this terminal descends, and then influence the quality of network, the waste interface-free resources, in today of interface-free resources growing tension, this waste to interface-free resources is extremely unadvisable.
Limit the frequent position renewal of terminal that is in the lane place intersection even two are provided with described threshold value, but for densely populated city, under the little situation of radius of society, the terminal that is in the lane place intersection still is easy to cross over the sub-district, thereby makes terminal be easy to satisfy above-mentioned threshold value and the generation that causes the position to be upgraded.
Summary of the invention
In view of this, the embodiment of the invention provides a kind of lane place collocation method, can realize that the free terminal of lane place boundary is selected to be suitable for resident sub-district most, and can reduce the position update times.
The embodiment of the invention also provides the method for a kind of Cell Broadcast CB lane place, can realize broadcasting the purpose of certain present a plurality of lane place, sub-district.
The embodiment of the invention also provides a kind of location updating method, can realize being positioned at the free terminal of lane place boundary and select to be suitable for most resident sub-district, thereby guarantee the access performance of terminal, and in densely populated city, under the little situation of radius of society, can reduce the updating of terminal position number of times that is in the lane place intersection.
The embodiment of the invention also provides a kind of position updating system, can realize being positioned at the free terminal of lane place boundary and select to be suitable for most resident sub-district, thereby guarantee the access performance of terminal.

Secondly, owing to exist same sub-district to be positioned at the situation of two lane place simultaneously, so the present invention also provides the method for Cell Broadcast CB lane place, realizes notifying terminal with the present a plurality of location area information in certain sub-district.
The 3rd, collocation method by above-mentioned lane place, may cause present paging policy paging user fully, for example, when certain lane place covered sub-district under a plurality of call centers Equipment Control, wherein any one call center's equipment can't notify the sub-district under other call center's Equipment Control that the user is carried out paging.So the embodiment of the invention provides a kind of paging method, solve the problem of above-mentioned incomplete paging.
At last, based on the above-mentioned lane place configuration mode and the method for Cell Broadcast CB lane place, the embodiment of the invention also provides a kind of location area updating method and system, when terminal is carried out the sub-district gravity treatment, whether the sub-district to be selected of judging terminal is in present position-region, if, then do not carry out the position and upgrade, upgrade otherwise carry out the position.Like this, for the terminal that is positioned at certain lane place boundary, when its when moving out the position district, the actual innerland that has moved to another lane place adjacent with this lane place, after carrying out the position renewal like this, even the boundary that this terminal continues to be wrapped up by present position-region in previous lane place carries out the sub-district gravity treatment, also can still be positioned at present position-region, and can not cause frequent location area updating because of it.
Introduce the embodiment of above-mentioned four aspects below respectively.
At first introduce the lane place collocation method in the embodiment of the invention.This method comprises: dispose two lane place in the call center at least, at least one sub-district is configured in primary importance district and the second place district simultaneously; With at least one cell configuration in the primary importance district, and outside second place district; With at least one cell configuration in second place district, and outside the primary importance district.Certainly in the actual disposition process, can dispose a plurality of lane place of satisfying above-mentioned condition in the scope that one or more call centers cover in communication network, constitute all places section model.
In the process in allocation position district, relate to several notions, be that non-overlap mode contact, overlap mode contact, border are wrapped respectively, bound edge and bound edge mutually, below these several notions are described:
One, two lane place are meant that with the non-overlap mode contact two lane place have the border overlapping, but do not exist any sub-district to be in simultaneously in these two lane place.
Two, two lane place are meant with the overlap mode contact, exist a sub-district to be in simultaneously in these two lane place at least.
Three, the border is wrapped and is meant, between two sub-districts of the border of La in Lb, then this part border of La is wrapped up by Lb.
Four, the lane place bound edge is meant the part or all of border of parcel another one lane place, a lane place.When the border of La parcel location district, lane place Lb: lane place La contacts with overlap mode with Lb, and exists a sub-district among the La of lane place outside the Lb of lane place.Be also referred to as the limit of La bag Lb.
Five, the mutual bound edge of La and Lb is meant: the limit of La bag Lb, and the limit of Lb bag La.
By three figure above-mentioned several notion is described intuitively respectively below.These three figure are respectively three kinds of execution modes of the invention described above lane place collocation method.
Fig. 2 is first kind of simple rectangle position section model.As shown in Figure 2:
L1 has covered sub-district C01～C08, C11～C19, C21～C28, C31～C39, C41～C48, C51～C59, or the like, these sub-districts have the L1 position region identification information; L2 has covered sub-district C31～C39, C41～C48, C51～C59, C61～C68, C71～C79, C81～C88, or the like.These sub-districts have the L2 position region identification information.Wherein, sub-district C31～C39, C41～C48, C51～C59 etc. are in L1 and these two lane place of L2 simultaneously.These are in the position region identification information that two sub-districts in the lane place have L1 and L2 respectively simultaneously.
In Fig. 2, L1 contacts with overlap mode exactly with L2; In fact also be mutual bound edge, here, L1 has only wrapped up a part of border of L2, and L2 also only comprises the segment boundary of L1.
Fig. 3 is a kind of simple circular lane place model.As shown in Figure 3:
L1 has covered the sub-district in the L1 external boundary, and these sub-districts have the L1 position region identification information; L2 has covered beyond the L2 inner boundary, the L2 external boundary is with interior sub-district, and these sub-districts have the L2 position region identification information.Wherein, be in simultaneously in L1 and these two lane place of L2 with interior, L2 inner boundary sub-district in addition at the L1 external boundary, these are in the position region identification information that two sub-districts in the lane place have L1 and L2 respectively simultaneously.
In Fig. 3, L1 also is to contact with overlap mode with L2; In fact also be mutual bound edge.Here, L2 has wrapped up all borders of L1, and L1 has wrapped up all inner boundaries of L2.In the practical application, can cover little cities and towns with L1, and cover the suburb in these cities and towns with L2.
Fig. 4 is second kind of rectangle position section model.As shown in Figure 4:
L1 has covered sub-district C01～C08, C12～C19, C21～C28, C32～C39, C41～C48 or the like, and these sub-districts have the L1 position region identification information; L2 has covered sub-district C21～C28, C31～C38, C41～C48, C51～C58, C61～C68 or the like, and these sub-districts have the L2 position region identification information; L3 has covered sub-district C51～C59, C61～C68, C71～C79, C81～C88 or the like, and these sub-districts have the L3 position region identification information.Wherein, sub-district C21～C28, C32～C38, C41～C48 etc. are in L1 and these two lane place of L2 simultaneously, and these sub-districts have the position region identification information of L1 and L2 respectively; Sub-district C51～C58, C61～C68 etc. are in L2 and these two lane place of L3 simultaneously, and these sub-districts have the position region identification information of L2 and L3 respectively.
In Fig. 4, L1 contacts with non-overlap mode exactly with L3, and L1 is to contact with overlap mode with L2, and L2 also is to contact with overlap mode with L3.
In like manner, in Fig. 5, any two lane place in three lane place of L1, L2 and L3 contact with overlap mode.
Above-mentioned three embodiments that figure promptly is a lane place collocation method in the embodiment of the invention.Certainly the configuration of lane place is not limited only to above-mentioned three kinds of modes.Introduce the multi-level positions section model of lane place of the present invention collocation method below.
For the covering of strip, as long and narrow island, when a lane place can cover the width in this area, can adopt two-layer intensive overlay model as Fig. 4, here, can be according to actual conditions, with lane place L2 to moving down or upwards moving.In the intensive overlay model, two lane place in lane place, centre and both sides in three lane place that link to each other exist overlapping, and two lane place, both sides contact with non-overlap mode.
Equally, for the covering of strip, also can adopt two-layer lax overlay model as Fig. 6.In the lax overlay model, two lane place in lane place, centre and both sides in three lane place that link to each other exist overlapping, and the not contact of two lane place, both sides.
For the covering in big zone, can adopt three layers of intensive lane place model shown in Figure 7, also can adopt three layers of slack position section model shown in Figure 8.
As shown in Figure 7, thick line hexagon, thick dashed line hexagon and fine rule hexagon can both independently cover separately continuously, these three layers of lane place are staggered to be covered, three lane place on same direction, thick line hexagon both sides are respectively thick dashed line hexagon and fine rule hexagon, thick dashed line hexagon both sides are respectively thick line hexagon and fine rule hexagon, and fine rule hexagon both sides are respectively thick dashed line hexagon and thick line hexagon.Except the border in whole zone, the border of any one lane place is all wrapped up by the lane place of other layer.Here, a sub-district only need be in maximum three lane place simultaneously.
As shown in Figure 8, thick line hexagon, thick dashed line hexagon and fine rule hexagon all can't independently cover whole zone separately continuously, and the three simultaneously as the covering that interlocks of figure mode, can finish the covering to whole zone together.Except the border in whole zone, the border of any one lane place is all wrapped up by the lane place of other layer.Here, a sub-district only need be in maximum three lane place simultaneously.
Equally,, can adopt four layers of intensive lane place model shown in Figure 9, also can adopt four layers of slack position section model shown in Figure 10 for the covering in big zone.
As shown in Figure 9, the ground floor lane place comprises: ABFG, CDHI, KLPQ, MNRS; Second layer lane place comprises: BCGH, DEIJ, LMQR, NOST; The 3rd layer of lane place comprises: FGKL, HIMN, PQUV, RSWX; The 4th layer of lane place comprises: GHLM, IJNO, QRVW, STXY.Each layer lane place can both cover a panel region continuously, and these four layers of lane place are staggered to be covered, and covers whole zone.Except the border in whole zone, the border of any one lane place is all wrapped up by the lane place of other layer.Here, a sub-district only need be in maximum four lane place simultaneously.
As shown in figure 10, the ground floor lane place comprises four pecked line quadrangle lane place, second layer lane place comprises two line segment dotted line quadrangle lane place, and the 3rd layer of lane place comprises two fine rule quadrangle lane place, and the 4th layer of lane place comprises a thick line quadrangle lane place.Continuous covering all can't be finished in each layer lane place, unless certain one deck lane place has only a lane place.The covering to whole zone as the covering that interlocks of figure mode, can be finished simultaneously together in four layers of lane place.Except the border in whole zone, the border of any one lane place is all wrapped up by the lane place of other layer.Here, a sub-district only need be in maximum four lane place simultaneously.
Intensive lane place model more multipass degree ground reduces the possibility on border, two non-overlapped lane place of terminal cross, also promptly steps out the possibility on border, lane place, but in the call center, the lane place data configuration can be corresponding more.
The intensive relatively lane place of slack position section model model, the possibility on border, two non-overlapped lane place of terminal cross increases, and the possibility of stepping out the border, lane place increases, but the lane place data configuration can be corresponding few in the call center.
In the middle of the practical application, carry out the lane place when covering for a more wide zone, can the above-mentioned all places of integrated application district overlay model, thus reach the two excellent of engineering and network quality.
The multi-level positions district of above-mentioned introduction is the model of two-layer, three floor and four floor, certainly according to the bound edge technology, can also form more multi-layered lane place configuration, and principle is identical, just repeats no more here.
The above-mentioned embodiment that is the lane place collocation method of the embodiment of the invention.After using these lane place collocation methods, may be in a plurality of lane place for same sub-district, according to the mode of present cell broadcast messages, present a plurality of lane place, this sub-district all can't be broadcast to the user, so the embodiment of the invention also provides a kind of Cell Broadcast CB method.This method specifically comprises: the identification information of preserving these present a plurality of lane place, sub-district in the base station that the sub-district belongs to; The Cell Broadcast CB position region identification information is disposable or several times the identification information of these present a plurality of lane place, sub-district is broadcast to terminal by the base station.
The concrete enforcement of said method can be divided into two major types: one, only broadcast the identification information of this present lane place, sub-district in the broadcast of sub-district, terminal is obtained the identification information of these present lane place, sub-district by receiving a plurality of sub-districts broadcast separately; Two, removing the present position region identification information in this sub-district of broadcasting in the broadcast of sub-district is, also further broadcast the present position region identification information of its neighbor cell, terminal promptly can be obtained the present position region identification information of this sub-district and neighbor cell thereof by the broadcast that receives this sub-district.Introduce this dual mode below respectively.
One, in the broadcast of sub-district, only broadcasts the identification information of this present lane place, sub-district.
At first be presented in the mode of preserving the Location Area Identification of sub-district correspondence in the base station.For example, the identification information of the sub-district of in the base station, managing according to this base station, a plurality of position region identification informations that in this base station each sub-district belonged to are preserved, with reference to shown in Figure 4, C52, C53 and C62 belong to three sub-districts of same BTS management, and be as shown in table 1.
Table 1
Cell ID Location Area Identification
C52 L2， L3
C53 L2， L3
C62 L2， L3
During Cell Broadcast CB, the base station obtains the present a plurality of position region identification informations in this sub-district according to cell ID from cell ID as shown in table 1 and position region identification information mapping table, and broadcast away by the cell broadcast messages one or many, like this, terminal can be obtained the identification information of present a plurality of lane place, a sub-district by cell broadcast messages.
Certainly, also can be with preserve a plurality of position region identification informations that each sub-district belongs to as following table 2:
Table 2
Cell ID Location Area Identification
C52 L2
C52 L3
C53 L2
C53 L3
C62 L2
C62 L3
Need to prove, when preserving the mapping table of cell ID and position region identification information, both can be the same with table 2 as table 1, the identification information of the sub-district of managing according to this base station, the a plurality of position region identification informations that in this base station each sub-district belonged to are preserved, and also can change a kind of form and carry out, promptly, according to the identification information of lane place, the cell identity information of in this base station this base station being managed is preserved in the base station; Table 3 for example:
Table 3
Cell ID Location Area Identification
L2 C52，C53，C62
L3 C52，C53，C62
Obviously, from table 3, also can obtain the present a plurality of position region identification informations in this sub-district according to cell ID.
In fact, table 2 also can be called according to position region identification information preservation cell ID.
Certainly, the base station also can adopt alternate manner to carry out when preserving a sub-district present position region identification information, for example, the identification information of present lane place, a sub-district and other parameter of this sub-district is saved in the data file together.
For the situation of a present position region identification information in sub-district more than one, during the Cell Broadcast CB position region identification information, can once broadcast away, for example, Extended Cell broadcast length, increase the broadcast location area amount of information, once the present position region identification information in this sub-district is broadcasted away.
The sub-district also can be broadcasted away the present a plurality of position region identification informations in this sub-district by repeatedly broadcasting.For example, can adopt the repeating query mode, once broadcast a position region identification information.For example, for sub-district C62 in the last table, the present position region identification information in this sub-district is L2 and L3, this sub-district is broadcasted for the first time and the position region identification information of L2 can be broadcasted away, broadcasting can be with the position region identification information of L3 for the second time, then, broadcast the position region identification information of L2 again, so broadcast (sites) in turn.In the practical application, other cell parameter information can be intercutted in the sub-district between the message of twice broadcast location area information.
For example, terminal is obtained the present one or more position region identification informations in this sub-district from this cell broadcast information; Judge the identification information that whether comprises described lane place in the present one or more position region identification informations in this sub-district that obtain, if then judging this sub-district is to be in the described lane place, otherwise, judge this sub-district and be not in the described lane place.
Terminal obtain the position region identification information that two sub-districts are co-located on mode can for: terminal is obtained the residing one or more position region identification informations in first sub-district as the first subdistrict position district identification information from first cell broadcast information, obtain the present one or more position region identification informations in second sub-district as the second subdistrict position district identification information from second cell broadcast information; Then, terminal is relatively stated the first subdistrict position district identification information and the described second subdistrict position district identification information, therefrom obtain identical position region identification information in two groups of position region identification informations, so just can obtain the position region identification information that first sub-district and second sub-district are co-located on.
Usually, the identification information of own present all lane place is only broadcasted in each sub-district, like this, terminal can be obtained the identification information of present all lane place of respective cell from the broadcast of each sub-district, in this case, terminal is obtained the identification information of the present lane place of current persistent district by the broadcast of current persistent district, obtains the identification information of its present each lane place of neighbor cell by the identification information of its neighbor cell.
Two, in cell broadcast messages, comprise this sub-district and the present position region identification information of this sub-district neighbor cell.
Certainly, in the message of Cell Broadcast CB except that the identification information that comprises this present lane place, sub-district, can further include the identification information of its present lane place of neighbor cell, for example, in the base station that the sub-district belongs to, further preserve the identification information in this present relevant position of sub-district neighbor cell district according to the identification information of this sub-district and the identification information of its neighbor cell, perhaps, in this cell configuration data, preserve the identification information of its present each lane place of neighbor cell, as shown in Figure 4, the neighbor cell of sub-district C62 has C52, C53, C61, C63,6 sub-districts such as C72 and C73, like this, the present position region identification information data of the neighbor cell of preserving in the configuration data of sub-district C62 can be with describing as following table 4:

C52 L2，L3
C53 L2，L3
C61 L2，L3
C63 L2，L3
C72 L3
C73 L3
If preserved the present position region identification information in self-administered a plurality of sub-district in the base station, and the present position region identification information of neighbor cell, so, can in table 4, increase the territory of a current area identification information, for example, C52, C53 and C62 belong to three sub-districts of same BTS management, such as following table 5 description:

Based on the configuration of table 4 or table 5, described base station may further include the sign of this sub-district neighbor cell and the identification information in the corresponding present relevant position of described neighbor cell district in cell broadcast messages.In this case, terminal only needs can obtain current persistent district and present each position region identification information of neighbor cell thereof by the broadcast of current persistent district.But can increase the amount of information of Cell Broadcast CB like this.
Is the concrete enforcement that example illustrates above-mentioned dual mode with the lane place numbering as Location Area Identification.
One, preferably, in cell configuration, preserve the identification information of these present all lane place, sub-district, thereby when broadcasting, in broadcast, comprised present lane place, this sub-district numbering of configuration in the sub-district, this lane place numbering may be more than one, the corresponding a plurality of lane place of difference.Terminal can be obtained current persistent district present lane place numbering and the present lane place of neighbor cell numbering from the broadcast of sub-district.When carrying out Cell Broadcast CB, the base station can be broadcasted away present all the lane place numberings in this sub-district disposable or several times, and terminal is obtained present lane place, sub-district number information by the broadcast singal that receives the sub-district.
Particularly, terminal obtain the present lane place of current area and neighbor cell numbering mode can for:
A, terminal can be obtained the present lane place of current area numbering from the broadcast of current area, and neighbor cell relevant parameter information, may further include the identification information of neighbor cell in this parameter information; Terminal can receive neighbor cell signal according to the parameter information of the neighbor cell that obtains, and obtains the lane place numbering of neighbor cell broadcasting from these signals, i.e. the present lane place of neighbor cell numbering.
B, terminal can directly adopt frequency modulation at random or alternate manner to intercept the broadcast singal of neighbor cell, and do not take from the broadcast of current area, to obtain the parameter information of neighbor cell, thereby intercept the mode of neighbor cell broadcast singal according to this parameter information.But, this directly at random frequency modulation or alternate manner intercept the mode of neighbor cell broadcast singal may be bigger to terminals consume.
Two, in cell configuration, both preserve the numbering of these present all lane place, sub-district, preserved the numbering of present each lane place of neighbor cell of this sub-district again.For example, the present lane place of neighbor cell numbering can be configured in the configuration data of current persistent district, also be, in the base station that current persistent district belongs to, further preserve the identification information in this present relevant position of sub-district neighbor cell district, thereby when current area is broadcasted, in broadcast, except that having comprised the present lane place of current area numbering, also further comprise the present lane place of neighbor cell numbering.Terminal is obtained the present lane place of neighbor cell number information from the broadcast singal of current area.But can increase the broadcast message amount of current area like this.
In above-mentioned dual mode, preserve the present position region identification information in described sub-district according to cell ID in call center that can also be further belongs in the sub-district or the base station controller, perhaps, preserved the cell identity information under the control of this call center or base station controller of belonging to that comprises in this lane place according to position region identification information, also be, preserve the corresponding relation of the present position region identification information in sub-district and this cell identity information in advance, the present position region identification information in sub-district that preserve the base station, can be after the base station powers on, from call center or base station controller, obtain.For example, the base station sends the request message that obtains the present position region identification information in sub-district to described call center or base station controller, carry cell identity information in the message, described call center or base station controller are after receiving this request, from the corresponding relation data of the present position region identification information in the sub-district of described preservation and this cell ID, obtain the present position region identification information in described sub-district according to cell identity information, and these position region identification informations that will obtain send to the base station.
But speak more greatly at present in the middle of the application, the corresponding relation of the present position region identification information in sub-district and this cell ID can directly be disposed in the base station by the engineer when network design.
By the way, terminal just can be known the corresponding configuration mode of call center to the lane place.
On the basis of above-mentioned lane place collocation method and Cell Broadcast CB lane place method, introduce the location updating method of the embodiment of the invention and the embodiment of system below.
Figure 11 is the overview flow chart of location updating method embodiment of the present invention.As shown in figure 11, this method comprises:
Step 1101, in call center's allocation position district, primary importance district and second place district are set at least, wherein will have at least a cell configuration becomes to be in simultaneously in primary importance district and the second place district, at least one cell configuration is become in the primary importance district and outside second place district, at least one cell configuration is become in second place district and outside the primary importance district.
This step is finished the configuration of two mutual bound edge lane place.
In this step, the mode of carrying out the lane place configuration is identical with aforesaid lane place configuration mode.
Described call center can be a call center resource pond, promptly can comprise one or more call centers equipment.
Each call center's equipment can establish a communications link with at least one sub-district, and having set up the sub-district of writing to each other with this call center's equipment is the sub-district of this call center's equipment.
Described lane place can comprise one or more sub-districts of call center's equipment, also can comprise one or more sub-districts of a plurality of call centers equipment.
For example, for the gsm communication network, call center's equipment can be a MSC/VLR equipment, and the call center can be the resource pool of one or more MSC/VLR equipment.
Step 1102, the sub-district is broadcast to terminal with present position region identification information own.
Step 1103 when terminal is carried out the sub-district gravity treatment, judges whether the sub-district to be selected of terminal is in present position-region, if then execution in step 1104, otherwise execution in step 1105.
Step 1104 is not carried out the position and is upgraded and process ends.
Step 1105 will be determined a lane place as the target location district in present one or more lane place, sub-district to be selected, carry out the position and upgrade.
In step 1101, primary importance district and second place district are actually two lane place of mutual bound edge.
In step 1105, after the position is updated to merit, may further include the described sub-district to be selected of execution and be set to the persistent district operation, and described target location district is set to present position-region.
In step 1105, can determine arbitrarily or at random from present one or more lane place, sub-district to be selected that directly a lane place is as the target location district; Perhaps, also can adopt certain strategy to determine the target location district; Or, can also obtain the number information of present lane place, sub-district to be selected earlier, whether the number of judging present lane place, sub-district to be selected is more than one, if, then from sub-district to be selected and the common residing lane place of current persistent district, determine the target location district, otherwise present lane place, sub-district to be selected as the target location district, is carried out the position and upgraded.
In step 1105, carrying out the position renewal can be that target location district identification information is sent to the call center, after the call center receives the target location district identification information of terminal transmission, the specified lane place of identification information, target location district that the present position-region of this terminal is set to receive.The call center can send a success message to terminal after the position is updated to merit, terminal is preserved target location district identification information as the present position-region identification information.
In the embodiment of the invention, judge that the mode whether a sub-district belongs to a lane place can be: terminal is obtained the present one or more position region identification informations in this sub-district from this cell broadcast information; Judge the identification information that whether comprises described lane place in the present one or more position region identification informations in this sub-district that obtain, if then judging this sub-district is to be in the described lane place, otherwise, judge this sub-district and be not in the described lane place.
Illustrating above-mentioned judgment mode is, suppose that terminal preserves the present position-region identification information, in addition, terminal gets access to the present one or more position region identification informations in sub-district to be selected from cell broadcast information to be selected, judging so whether sub-district to be selected is in the present position-region is meant: judge in the present one or more position region identification informations in sub-district to be selected that obtain whether comprise the present position-region identification information, if, then judging sub-district to be selected is to be in the present position-region, otherwise, judge sub-district to be selected and be not in the present position-region.
When terminal judges oneself is not preserved the present position-region identification information, from current persistent district broadcast message, obtain the residing one or more position region identification informations of current persistent district, one of them position region identification information is saved as the present position-region identification information, and initiate the position and upgrade.
Terminal obtain the position region identification information that current persistent district and sub-district to be selected be co-located on mode can for: terminal can be obtained the residing one or more position region identification informations of current persistent district as current persistent district position region identification information from current persistent district broadcast message, and obtains the present one or more position region identification informations in sub-district to be selected as subdistrict position to be selected district identification information from cell broadcast information to be selected; Terminal can therefrom be obtained the position region identification information that sub-district to be selected and current persistent district are co-located on by more current persistent district position region identification information and subdistrict position to be selected district identification information.
The position region identification information here can be Location Area Identification itself or lane place sequence number, for example concerning Location Area Identification of the present invention for the gsm system, can be Location Area Identification LAI (Location AreaIdentification) or Location Area Code LAC (Location Area Code).
Figure 12 is the overall construction drawing of updating of terminal position system embodiment of the present invention.As shown in figure 12, this system comprises: call center 1210, base station 1220 and terminal 1230.
In this system, call center 1210, be used for the allocation position district, at least comprise primary importance district and second place district, wherein, have at least a sub-district to be in simultaneously in primary importance district and the second place district, have a sub-district in the primary importance district at least outside second place district, and have a sub-district in the second place district at least outside the primary importance district; Also be used for the target location district identification information that receiving terminal sends, carry out the position and upgrade.
Base station 1220 is used for from the call center 1210 and obtains the present position region identification information of respective cell of transmission, and is distributed to terminal 1230 by cell broadcast messages.
Terminal 1230, be used for receiving the present position region identification information of respective cell that issue at Cell Broadcast CB base station 1220, when terminal is carried out the sub-district gravity treatment, whether the sub-district to be selected of judging terminal is in present position-region, if, then do not carry out the position and upgrade, otherwise, from present lane place, sub-district to be selected, determine the target location district, carry out the position and upgrade.
In the said system structure, terminal 1230 is not directly to link to each other with 1210 of call centers, the network equipment by other between the two links to each other, and therefore dot the annexation of the two, but the final goal Location Area Identification can send to call center 1210.
The above-mentioned overview that is the embodiment of the invention by above-mentioned lane place bound edge technology, makes when carrying out the sub-district gravity treatment, can select to be suitable for most resident sub-district as required.
Particularly, be example with Fig. 2, adopt mutual bound edge mode to carry out the division of lane place L1 and L2.Since the border of L1 parcel L2, the border of L2 parcel L1, thereby the terminal present position-region variability that the boundary that the reduction portable terminal wraps up mutually two lane place caused when carrying out the position renewal.
Because the lane place is handled by bound edge, like this, when the border, lane place of being wrapped up of terminal in-position district L1, in fact, also just arrive the innerland of lane place L2 by L2, in this case, when the position is updated to L2, because terminal is in the innerland of L2, rather than the border of L2, phenomenon is upgraded in the position repeatedly of having been caused when therefore, just having avoided terminal to be in the border, lane place.
Be in simultaneously among lane place L1 and the L2 in the sub-district of L1 and L2 overlapping, can comprise the position region identification information of L1 and L2 in these community configured informations; In the broadcast singal of these sub-districts, also can comprise the position region identification information of L1 and L2.
During updating of terminal position, selected lane place can be registered to the call center of network, for example in the GSM network, Location Area Identification can be sent to and carry out the lane place registration among the VLR.When the terminal re-selecting cell, judge when sub-district to be selected does not belong to present position-region, initiate the position and upgrade, the position is updated to new lane place.Mode is preferably, and whether terminal judges sub-district to be selected and current area exist common lane place, if exist, just the position is updated to this common lane place.
For originally with non-overlap mode position contacting district, as L1 among Fig. 4 and L3, the present invention program be to allow these two with non-overlap mode position contacting district at adjacent, perhaps boundary, carry out mutual bound edge, make it as shown in Figure 2 with overlap mode contact, the mutual bound edge of L1 wherein and L2.
In community configured information, comprise the present position region identification information in this sub-district, in the message of this Cell Broadcast CB, comprised the present position region identification information in this sub-district of configuration, for example number the lane place, thereby the lane place is divided the purpose of result notification terminal in the realization sub-district.The lane place numbering that comprises in the message of Cell Broadcast CB may be more than one, the corresponding a plurality of lane place of difference.
The method of above-mentioned Cell Broadcast CB position region identification information can adopt aforesaid execution mode, and terminal can be known the lane place configuration information that carries out the call center, i.e. the present position region identification information in sub-district.So terminal judges earlier in the numbering of present lane place, sub-district to be selected (Cij) whether exist terminal in the lane place of network side registration numbering, promptly present position-region is numbered, if exist, then terminal is chosen as Cij with current persistent district before re-selecting cell; If do not exist terminal in the lane place of network side registration numbering in the numbering of the present lane place of Cij, then terminal is initiated more new technological process of position, and the position is updated to the present lane place of Cij.Preferable scheme is if Cij and current persistent district (Cdock) when having common present lane place, are selected Cij and the common present lane place of Cdock as present position-region, and after the position is updated to merit, current persistent district are chosen as Cij.
When for example the terminal judges signal quality that goes out a sub-district Cij is better than the signal quality of current persistent district Cdock, can start the above-mentioned sub-district flow process of reselecting.
When above-mentioned terminal is carried out the sub-district gravity treatment at the intersection of lane place L1 and L2,, then do not initiate more new technological process of position, and be Cij only the sub-district gravity treatment if when finding that sub-district Cij to be selected is in own current lane place of registering in the call center.If find the lane place that sub-district to be selected is to one's name not current, then initiate more new technological process of position.For example present position-region is lane place L1, and terminal has been preserved the position region identification information of registering in the call center here.
Terminal is being initiated the position more during new technological process, and processing mode is to judge earlier whether Cij and Cdock are co-located on certain or some lane place preferably, if then select a lane place in the common present lane place as present position-region.
With Fig. 2 is that example explanation said process is: the supposition present position-region is L1, and Cdock is C56, and then when Cij was C55 or C57 or C45 or C46, terminal was not carried out the position and upgraded when re-selecting cell; When Cij was C65 or C66, because C65 or C66 do not belong to lane place L1, therefore, terminal also will be carried out the position and be upgraded when re-selecting cell.With Cij is that C66 is an example, when terminal is upgraded in the position, selects L2 as the target location district that upgrades.Certainly, the common lane place of C66 and C56 also is L2 here.
Under lane place model shown in Figure 2, after terminal is updated to L2 from sub-district C56 gravity treatment to sub-district C66 and with present position-region, when terminal because the reason that signal reason or user move, during again from sub-district C66 gravity treatment to sub-district C56, terminal judges C56 also belongs to L2, therefore, upgraded with regard to not carrying out the position again.Like this, terminal just can not occur the problem that frequent executing location is upgraded because of the border of being wrapped up by L2 that is in L1.
Accordingly, when the terminal present position-region is L2, after being updated to L1 from sub-district C33 gravity treatment to sub-district C22 and with present position-region, when terminal because the reason that signal reason or user move, during again from sub-district C22 gravity treatment to sub-district C33, terminal judges C33 also belongs to L1, therefore, just can not upgrade carrying out the position.Like this, terminal just can not occur the problem that frequent executing location is upgraded because of the border of being wrapped up by L1 that is in L2.
Certainly, in the practical application, the terminal re-selecting cell have more than be with the cell signal quality as unique criterion, terminal it is also conceivable that other factorses such as sub-district busy extent, just repeats no more here.
Therefore the present invention can solve in the prior art effectively, when terminal is rocked on certain border, lane place, and caused frequent position replacement problem.
As previously mentioned, when determining the target location district, have in the embodiment of the invention four kinds of situation: a, from the lane place that current area and sub-district to be selected are co-located on definite target location district; Residing lane place, sub-district to be selected number is judged by b, elder generation, determines the target location district again; C, directly at random or any-mode determine the lane place; D, according to the position of present each lane place of terminal and sub-district to be selected relation, determine the lane place.For three embodiment, the embodiment of location updating method of the present invention is described respectively under ab, ac, three kinds of combined situation of ad below.
Location updating method embodiment one:
In the present embodiment, when definite target location district, at first judge the number of present lane place, sub-district to be selected, determine the target location district according to this number then.
Figure 13 is the particular flow sheet of Position Updating method embodiment one of the present invention.As shown in figure 13, this method comprises:
Step 1301 in the call center, is provided with the lane place of two mutual bound edges at least.
For example two lane place of She Zhiing are primary importance district and second place district, at least one cell configuration is become to be in simultaneously in described primary importance district and the described second place district, at least one cell configuration is become in described primary importance district and outside described second place district, at least one cell configuration is become in second place district and outside described primary importance district.In this step, certainly the lane place allocation models with reference to aforesaid various bound edges carries out the configuration of lane place.
Step 1302, the sub-district is broadcast to terminal with present position region identification information own.
In this step, the mode that the base station at place, sub-district obtains this present position region identification information in sub-district can be the identification information of the present one or more lane place of allocating cell, call center, when the base station powers on, obtain the present position region identification information in this sub-district from the call center, and the present position region identification information in this sub-district is configured in the base station; Perhaps, when networking at first, the present position region identification information in this sub-district is configured in the base station.For the GSM network, this call center can be MSC/VLR.Accordingly, for gsm system, also can when powering on, can obtain the present position region identification information in this sub-district by the identification information of the present one or more lane place of base station controller (BSC) allocating cell from BSC in the base station.
The base station with the concrete mode that position region identification information is broadcast to terminal is: further comprise the identification information of these present one or more lane place, sub-district in cell broadcast information, the base station is disposable or several times these position region identification informations are broadcast to terminal.This mode also is the method embodiment of the Cell Broadcast CB position region identification information that provides of the embodiment of the invention.
Step 1303 when terminal is carried out the sub-district gravity treatment, judges whether the sub-district to be selected of terminal is in present position-region, if then execution in step 1304, otherwise execution in step 1305.
Step 1304 is not carried out the position and is upgraded and process ends.
Step 1305, the call center judges whether the number of present lane place, sub-district to be selected is one, if then execution in step 1306, otherwise, execution in step 1307.
Step 1306 as the target location district, is carried out present this lane place, sub-district to be selected the position and is upgraded, and process ends.
Step 1307 is determined the target location district from the lane place that sub-district to be selected and current persistent district are co-located on, carry out the position and upgrade.
In step 1306, when present lane place, sub-district to be selected is one, also can be according to the processing mode of terminal re-selecting cell in the existing GSM network, carry out: judge whether the signal strength signal intensity of sub-district to be selected and the signal strength difference of current persistent district reach preset threshold value, if reach described preset threshold value, then with sub-district to be selected as persistent district, and lane place that will this sub-district to be selected is carried out the position as the target location district and is upgraded; Otherwise, do not carry out sub-district to be selected as persistent district, do not carry out yet and determine target location district and follow-up location update operations.
Preferably, the number in present lane place, sub-district to be selected is in the time of one, can judge whether current persistent district is in the lane place of sub-district to be selected, if, then can be directly with this lane place as the target location district.If judge in the lane place that current persistent district is not in sub-district to be selected, then again according to the processing mode that has terminal re-selecting cell in the GSM network now, judge whether the signal strength signal intensity of sub-district to be selected and the signal strength difference of current persistent district reach preset threshold value, if reach described preset threshold value, then with sub-district to be selected as persistent district, and lane place that will this sub-district to be selected is carried out the position as the target location district and is upgraded; Otherwise, do not carry out sub-district to be selected as persistent district, do not carry out yet and determine target location district and follow-up location update operations.
In step 1306, can judge further whether current persistent district is in the lane place of sub-district to be selected, if be in, lane place that then will this sub-district to be selected is as the target location district.With lane place model shown in Figure 2 is example: suppose that current persistent district is C32, present position-region is L2, and sub-district to be selected is C22, the present lane place of C22 number is 1, and promptly lane place L1 is obvious, C32 is among the lane place L1 of C22, here can be with L1 as the target location district.
In the middle of the reality, when existing two lane place to contact, the situation in the lane place that current persistent district is not in sub-district to be selected may occur judging, at this moment, can carry out the sub-district gravity treatment with reference to the residence reselecting of GSM prior art with non-overlap mode.With lane place model shown in Figure 4 is example, suppose that present position-region is L1, current area is C48, sub-district to be selected is C59, here, C59 has only present lane place this lane place of L3, and current persistent district C48 is not among the L3, like this, just can handle with reference to the existing sub-district of GSM reselection modes.For example: can preset a difference in signal strength threshold value, judge whether the signal strength signal intensity of sub-district to be selected and the signal strength difference of current persistent district reach preset threshold value, if reach described preset threshold value, lane place that then will this sub-district to be selected is as the target location district, otherwise, do not carry out and determine target location district and follow-up location update operations.
Here, terminal is obtained the present one or more position region identification informations of current persistent district from current persistent district broadcast message; Judging whether current persistent district is in this lane place of sub-district to be selected can be: judge the identification information that whether comprises this lane place of described sub-district to be selected in the present one or more position region identification informations of current persistent district that obtain, if, then judging current persistent district is to be in this lane place of sub-district to be selected, otherwise, judge in this lane place that current persistent district is not in sub-district to be selected.
In step 1306, when judging present lane place, sub-district to be selected and be one, can not judge also whether current persistent district is in the operation in the lane place of sub-district to be selected, but lane place that directly will this sub-district to be selected is as the target location district.This situation is effective especially when each lane place only contacts with overlap mode with other lane place in a communication network.Certainly, also can handle, just repeat no more here with reference to the existing sub-district of said GSM reselection modes.
In step 1307, before from sub-district to be selected and the common present lane place of current persistent district, determining the target location district, can judge further whether sub-district to be selected and current persistent district exist the lane place that is co-located on, if exist, then carry out the described operation of from sub-district to be selected and the common residing lane place of current persistent district, determining the target location district, otherwise, select in present a plurality of lane place, sub-district to be selected one as the target location district, for example, from present a plurality of lane place, sub-district to be selected, select arbitrarily or at random a lane place as of target location district as the target location district.
In step 1307, when the lane place that sub-district to be selected and current persistent district are co-located on has only one, directly with this lane place as the target location district.With lane place model shown in Figure 4 is example: suppose that current persistent district is C43, present position-region is L1, and sub-district to be selected is C53, and the present lane place of C53 number is 2, i.e. lane place L2 and L3, and obviously, the lane place that C32 and C22 were co-located on is L2.Here with L2 as the target location district.
In step 1307,, select in a plurality of lane place that sub-district to be selected and current persistent district be co-located on one as the target location district when lane place that sub-district to be selected and current persistent district are co-located on during more than one.For example, from a plurality of lane place that these two sub-districts are co-located on, select a lane place arbitrarily or at random as the target location district.With lane place model shown in Figure 5 is example: suppose that current persistent district Cdock is C53, present position-region is L1, sub-district to be selected is C62, the lane place number that C62 and C53 were co-located on is 2, be lane place L2 and L3, in this case, can from C53 and C62, select a lane place arbitrarily or at random as the target location district, for example, select L3 as the target location district.
In the step 1307 of present embodiment, when determining the target location district, from the lane place that sub-district to be selected and current persistent district are co-located on, select.In fact, also can be from present a plurality of lane place, sub-district to be selected determine a lane place as the target location district at random or arbitrarily, not necessarily must in the lane place that sub-district to be selected and current persistent district are co-located on, select.
In the present embodiment, after the position is upgraded successfully, may further include terminal with described sub-district to be selected as persistent district, and described target location district identification information preserved as the present position-region identification information.For example, the call center upgrades success message with the position and sends to terminal, and terminal knows by this message whether successful the position is upgraded.
The idiographic flow of the location updating method of the above-mentioned terminal that provides for present embodiment, present embodiment also provides a kind of concrete structure of position updating system of terminal, can be used to implement above-mentioned location updating method.Figure 14 is the concrete structure figure of the position updating system of terminal in the embodiment of the invention one.As shown in figure 14, this system comprises: call center 1210, base station 1220 and terminal 1230.Wherein, terminal 1230 comprises receiver module 1231, main control module 1232 and sending module 1233.
In this system, call center 1210, be used for the allocation position district, at least comprise primary importance district and second place district, and have at least a sub-district to be in simultaneously in primary importance district and the second place district, have a sub-district in the primary importance district at least outside second place district, and have a sub-district in the second place district at least outside the primary importance district; Also be used to receive the target location district sign that described terminal sends, carry out the position and upgrade.
Base station 1220 is used for from the call center 1210 and obtains the present position region identification information in self-administered sub-district of transmission, and is distributed to terminal 1230 by cell broadcast messages.
In terminal 1230, receiver module 1231 is used to receive base station 1220 in cell broadcast messages, comprises all Location Area Identification under the base station in this message, and this broadcast is sent to main control module 1232.Main control module 1232, be used to receive the cell broadcast messages that comes from receiver module 1231 forwardings, the sub-district gravity treatment is carried out in decisions such as signal(l)ing condition according to each sub-district in the message, and whether be in present position-region according to sub-district to be selected and determine whether to carry out the position and upgrade, when determining that carrying out the position upgrades, lane place with sub-district to be selected and current persistent district under common is as the target location district, and notice sending module 1233 carries out the position and upgrades.Sending module 1233, the target location district sign that is used for being received from main control module 1232 sends to call center 1210.
In the embodiment of said system, the sending module 1233 of terminal 1230 is not directly to link to each other with 1210 of call centers, and the network equipment by other between the two links to each other, but the final goal Location Area Identification can send to call center 1210.
When carrying out the position renewal with system according to the method described above, for the terminal that is in certain lane place boundary, after it carries out the sub-district gravity treatment and initiates the position renewal, because with its location area updating is the common affiliated lane place of sub-district to be selected and current persistent district, therefore, even terminal is because problems such as signal or service quality when original persistent district is returned in gravity treatment again, also do not need to carry out the position again and upgrade, the terminal of having avoided the lane place boundary is because the sub-district problem of the lane place frequent updating that causes of gravity treatment repeatedly.Because the problem of location district frequent updating needn't not be provided with the position renewal of threshold value limiting terminal naturally, make terminal freely to select to be suitable for most resident sub-district according to network condition.
Therefore the present invention can solve in the prior art effectively, when terminal is rocked on certain border, lane place, and caused frequent position replacement problem.
In the middle of the reality, when definite target location district, can not carry out earlier whether the number of judging present lane place, sub-district to be selected is one operation yet, but directly from residing lane place, sub-district to be selected, determine the target location district.The following examples will be the embodiment of example explanation location updating method with this kind situation.
Location updating method embodiment two:
Figure 15 is the particular flow sheet of Position Updating method embodiment two of the present invention.As shown in figure 15, this method comprises:
Step 1501 in the call center, is provided with the lane place of two mutual bound edges at least.
In this step, can adopt aforesaid lane place separately configuration mode to carry out the location area information configuration of sub-district.
Step 1502, the sub-district is broadcast to terminal with present position region identification information own.
In this step, the base station at place, sub-district obtains the mode of this position, sub-district district identification information and Cell Broadcast CB position region identification information and gives the mode of terminal can be identical with embodiment one, just repeats no more here.
Step 1503 when terminal is carried out the sub-district gravity treatment, judges whether the sub-district to be selected of terminal is in present position-region, if then execution in step 1504, otherwise execution in step 1505.
Step 1504 is not carried out the position and is upgraded and process ends.
Step 1505 is determined the target location district from sub-district to be selected and the common residing lane place of current persistent district, carry out the position and upgrade.
In step 1505, when the lane place that sub-district to be selected and current persistent district are co-located on is one, can be directly with this lane place as the target location district.When lane place that sub-district to be selected and current persistent district were co-located on for more than one the time, select that sub-district to be selected and current persistent district be co-located on more than a lane place in the lane place as the target location district, for example, from the lane place that these are co-located on, select one at random or arbitrarily as the target location district.
In step 1505, when the lane place that sub-district to be selected and current persistent district are co-located on does not exist, can select a lane place in present one or more lane place, sub-district to be selected as the target location district.For example therefrom select a lane place as the target location district arbitrarily or at random.
In the present embodiment, after the position is upgraded successfully, may further include terminal with described sub-district to be selected as persistent district, and described target location district identification information preserved as the present position-region identification information.For example, the call center upgrades success message with the position and sends to terminal, and terminal knows by this message whether successful the position is upgraded.
Difference among method flow in the present embodiment and the embodiment one is, when determining the target location district, directly selects a lane place in one or more lane place that sub-district to be selected and current area be co-located on as the target location district.Identical among the operation of other step and the embodiment one, the method flow in the present embodiment can be implemented in system shown in Figure 14 equally.
In the embodiment of the invention, when definite target location district, if there is a plurality of selectable locations district, that is, sub-district to be selected is in a plurality of lane place simultaneously, can be arbitrarily or select one of them lane place as the target location district at random; Also can select a lane place as the target location district according to certain strategy.The following examples are promptly introduced location updating method in such cases.
Location updating method embodiment three:
In the present embodiment, when definite target location district, determine the target location district, be specially: select with respect to the position in each selectable location district further combined with the terminal current location according to certain strategy.
Identical among the flow process of present embodiment Position Updating and the embodiment two, just in step 1505, when lane place that sub-district to be selected and current persistent district were co-located on for more than one the time, concern to determine the target location district according to the current position of terminal with respect to each selectable location district.
In the present embodiment, adopt the terminal current location to the distance of each selectable location district center as the standard of selecting, the chosen position district center apart from nearest that lane place of terminal as the target location district.The mode of the concrete lane place that sets the goal really has two kinds:
One, the geographical location information at center, Cell Broadcast CB lane place, terminal is determined the target location district.
A in step 1502, may further include the geographical location information at the center, lane place of preserving in advance in the Cell Broadcast CB signal, terminal is obtained the geographical location information at center, lane place by receiving broadcasting information.
B, in step 1505, terminal can adopt GPS localization method or mobile network's base station positioning method to obtain the geographical location information of oneself, and terminal is by the geographical location information at geographical location information that compares oneself and the center, lane place that obtains, and obtaining oneself puts in place puts the distance of district center.
C, in step 1505, select terminal to the minimum lane place of the distance of position district center as the target location district, carry out the position and upgrade.
Two, the geographical location information of Cell Broadcast CB center of housing estate, terminal is determined the target location district.
A, in step 1502, terminal also can be obtained the geographical location information of oneself according to the geographical location information of center of housing estate to be selected, for example, directly with the geographical location information of center of housing estate to be selected geographical location information as oneself, may further include in advance the geographical location information of the center of housing estate of preserving in the Cell Broadcast CB signal, terminal is obtained the geographical location information of center of housing estate by receiving broadcasting information, and with its geographical location information as oneself.According to the method for " ", terminal can obtain the position relation at the center of own and present a plurality of lane place, sub-district to be selected.
In the middle of the reality, the geographical location information of center of housing estate can be a misalignment degree information, be the misalignment degree information at center of housing estate and center, lane place, for example, can amount to 16 values with 0～15 and represent this misalignment degree: 0 expression center of housing estate distance and position district center is for being less than or equal to 100 meters, 1 expression center of housing estate distance and position district center is greater than 100 meters, be less than or equal to 300 meters, 2 expression center of housing estate distance and position district centers are greater than 300 meters, be less than or equal to 500 meters, 3 expression center of housing estate distance and position district centers are greater than 500 meters, are less than or equal to 700 meters or the like.
B, in step 1505, terminal can the misalignment degree value of sub-district more to be selected in each lane place that it lays oneself open to, and select the less lane place of misalignment degree to carry out the position as the target location district and upgrade.
After using above-mentioned dual mode and determining the target location district, can guarantee that terminal after the position is upgraded, as much as possible makes to lay oneself open to the nearer place of distance and position district center, promptly make terminal be in the central area, lane place as far as possible.
Equally, in the cell broadcast messages, can comprise that also center of housing estate arrives the minimum range reference value on the border of each lane place, this reference value can be an actual distance value, also can be a border irrelevance information, for example, can amount to 16 values with 0～15 and represent this border irrelevance: the minimum range on 0 expression border, center of housing estate distance and position district is for being less than or equal to 100 meters, the minimum range on 1 expression border, center of housing estate distance and position district is greater than 100 meters, be less than or equal to 300 meters, the minimum range on 2 expression borders, center of housing estate distance and position district is greater than 300 meters, be less than or equal to 500 meters, the minimum range on 3 expression borders, center of housing estate distance and position district is greater than 500 meters, is less than or equal to 700 meters or the like.Like this, when definite target location district, can select in the minimum value on border, center of housing estate distance and position district, the maximum pairing lane place of that minimum value perhaps selects the pairing lane place of irrelevance maximum, border as the target location district as the target location district.Also promptly, frontier distance center of housing estate that lane place farthest in chosen position district is as the target location district, like this, can make terminal after the position is upgraded be in the heartland of lane place as far as possible.Here, the distance of border, lane place and center of housing estate is the minimum value of center of housing estate to the border, lane place.
Certainly, also can be in the middle of the reality with the minimum range on cell boarder and border, lane place as the border irrelevance, equally, and when definite target location district, can be with the lane place of this border irrelevance maximum as the target location district.Cell boarder and border, lane place have and intersect or when overlapping, this irrelevance value is 0.Here, when cell boarder was outside the border, lane place, can also to arrange this irrelevance value also be 0 or be a negative value, for example is-1.
The method flow of present embodiment can be implemented in system shown in Figure 14 equally.
Adopt above-mentioned strategy to carry out the selection of lane place, can guarantee that after carrying out the sub-district gravity treatment, terminal is in the central area of certain lane place, thus greatly reduce that frequent position that terminal causes because of moving around upgrades may.
In the middle of the reality, carry out determining when the position is upgraded the consumption in target location district in order to reduce terminal, can inform directly in the cell broadcast messages that terminal is when definite target location district, the lane place scope that should select, these can be by in a plurality of Location Area Identification of Cell Broadcast CB, directly specify certain several or some Location Area Identification as position candidate district sign, to dwindle the scope of terminal select target lane place.For example, directly with the lane place of some Location Area Identification correspondences as the position candidate district, like this, when terminal identifies in definite target location district, directly with this position candidate district as the target location district, can reduce terminal like this because of determining the caused consumption in target location district.Here for ease of describing, with the position candidate district in the present lane place, a sub-district as the master site district, with those non-position candidate districts in the present lane place, a sub-district as secondary lane place.When preserving the present position region identification information in this sub-district in the community configured information, which lane place is the master site district in the present lane place, a sub-district in order to distinguish can to increase a major-minor mark, and which lane place is secondary lane place.With reference to Fig. 4, have as shown in table 6 belowly, the lane place of representing this Location Area Identification correspondence when major-minor is labeled as 0 is the master site district of this sub-district, represents the secondary lane place of the lane place of this Location Area Identification correspondence for this sub-district when major-minor is labeled as 1.

As can be seen from Table 6, when being a cell configuration master site district, generally can select those to make this sub-district be used as the master site district of this sub-district more near the lane place of its central area.Certainly, in the middle of the reality, can also dispose the master site district of a sub-district according to other factors.
In the middle of the reality, also master site district identification information can be left in respectively in the different memory block with secondary position region identification information.For example, under the certain situation of master site district sign quantity, master site district identification information is placed on the front of a tabulation, secondary position region identification information is placed on the back of this tabulation.With reference to Fig. 4, have as shown in table 7 belowly, suppose in present each lane place, a sub-district, have only the master site district of a lane place for this sub-district, like this, the master site district of this sub-district sign is placed on the front, secondary Location Area Identification is placed on the back of the master site district sign of this sub-district.

When Cell Broadcast CB master site district sign and secondary Location Area Identification, master site district sign and secondary Location Area Identification are distinguished.For example, location mode according to above-mentioned master site district sign and secondary Location Area Identification, each lane place of using a major-minor mark to distinguish each Location Area Identification correspondence of broadcasting is respectively master site district or secondary lane place, like this, terminal can be distinguished master site district sign and secondary Location Area Identification according to this major-minor mark.Perhaps distinguish the major-minor lane place with different data blocks, for example, comprise simultaneously that in a broadcast major-minor Location Area Identification is, master site district sign is placed on the front of secondary Location Area Identification, like this, to give tacit consent to the lane place of first Location Area Identification correspondence be the master site district to terminal.
When Cell Broadcast CB master site district sign and secondary Location Area Identification, also can use different message to broadcast master site district sign and secondary Location Area Identification respectively to master site district sign and the differentiation that secondary Location Area Identification carries out, terminal is distinguished master site district sign and secondary Location Area Identification according to different message code values.
Terminal can be to obtain present master site district, this sub-district sign and/or secondary Location Area Identification earlier when judging whether a sub-district belongs to a lane place; Judge whether described lane place is in the master site district and identifies pairing lane place or whether be in the pairing lane place of secondary Location Area Identification, if then this sub-district is in described lane place, otherwise this sub-district is not in described lane place; Perhaps, judge whether the Location Area Identification of described lane place is included in master site district sign or the secondary Location Area Identification, if then this sub-district is in described lane place, otherwise this sub-district is not in described lane place.
When terminal was not in the present position-region in sub-district to be selected, terminal need be determined the target location district.When terminal is determined the target location district, can be from the broadcast singal of sub-district to be selected, to parse master site district identification information earlier, then determine the target location district according to master site district identification information.When master site district sign has only one, just can be directly with this master site district as the target location district.That is to say that when the terminal re-selecting cell, if determine that a sub-district is sub-district to be selected, and the master site district sign of this sub-district has only one, then, terminal can directly be defined as the target location district with this corresponding lane place of sign, master site district.And also determine sub-district to be selected when wanting the sub-district of gravity treatment when terminal, terminal can judge whether the master site district of this sub-district to be selected has covered the current area of terminal, promptly, the master site district sign that whether has comprised sub-district to be selected in the present secondary Location Area Identification of the current area of terminal, if, then can select this sub-district to be selected is Target cell, and the master site district of this sub-district to be selected as the target location district, is carried out sub-district gravity treatment and position and upgrades.If do not comprised the master site district sign of sub-district to be selected in the present secondary Location Area Identification of the current area of terminal, so, terminal can be earlier directly should sub-district to be selected be defined as Target cell and carries out the sub-district gravity treatment, terminal can judge further that whether the signal quality of sub-district to be selected is obviously because the signal quality of current area, this can decide by a signal quality parameter difference, if cell signal quality to be selected obviously is better than current area, then, terminal can be considered will this sub-district to be selected to carry out the sub-district gravity treatment and master site district that will this sub-district to be selected carries out the position renewal as the target location district as Target cell.Certainly, when determining whether that sub-district to be selected carried out the sub-district gravity treatment as Target cell, can also be further with reference to the traffic load of sub-district to be selected, this traffic load parameter value can be broadcast out by cell broadcast messages, terminal obtains the traffic load situation of sub-district to be selected by resolving this message.
Can preserve the present position-region identification information in the terminal, during the terminal re-selecting cell, when judging sub-district to be selected and be not in present position-region, from the present master site in sub-district to be selected district, determine the target location district, carry out the position and upgrade.The identification information in present master site district, this sub-district to be selected and the identification information of secondary lane place are preserved in the base station that described sub-district to be selected belongs in the configuration information of this sub-district to be selected, the identification information that described base station will present master site district, this sub-district to be selected and the identification information of secondary lane place are broadcasted away; Terminal can receive described master site district's identification information and secondary position region identification information.
Whether terminal judges present position-region sign is included in described master site district's identification information and the secondary position region identification information, if, then judge this sub-district to be selected and be in described present position-region, otherwise, judge this sub-district to be selected and be not in described present position-region.
Terminal is before definite target location district from the present master site in sub-district to be selected district goes forward side by side the line position renewal, can also judge whether current area is in the described master site district, if, then carry out this master site district is defined as the operation that line position upgrades of going forward side by side of target location district, otherwise, determine whether to carry out the go forward side by side operation of line position renewal of sub-district gravity treatment according to this sub-district to be selected according to cell signal quality to be selected or Zone load to be selected.
The terminal gravity treatment can carry out the position during sub-district and upgrade, target location district identification information is sent to the call center, the target location district identification information that call center's receiving terminal sends, the present position-region of this terminal is set to the specified lane place of identification information, described target location district.Terminal saves as the present position-region identification information with target location district identification information after the lane place is upgraded successfully.
In the community configured information, master site district sign and secondary position region identification information can be to be configured to period in the base station that this sub-district belongs in networking, also can be configured according to cell identity information in the base station controller of this base station or its corresponding paging center.After the base station powers on, can obtain the present master site of respective cell district's identification information and secondary position region identification information from base station controller or its corresponding paging center of correspondence, for example, obtain the present master site of respective cell district's identification information and secondary position region identification information according to the identification information of sub-district or base station identification information from base station controller or its corresponding paging center of correspondence.
In the mechanism of major and minor lane place, the master site district is used for terminal and determines the target location district fast, and, in most cases, when being a cell configuration master site district, only disposing a master site district and get final product.The position that can adapt to like this under the terminal fast moving situation is upgraded, and improves the position and is updated to power.
After through the configuration of above-mentioned all places district, may have such situation: some lane place have covered the sub-district under two above call center Equipment Control.At this moment, if adopt traditional paging mode to carry out paging terminal, the situation that the interior part sub-district of this lane place coverage does not have call terminal may appear then.Therefore, need to change paging policy, so that paging is all initiated to terminal in all sub-districts under this lane place covering.
Figure 16 is the flow chart at the paging method embodiment of above-mentioned situation.Suppose that in the present embodiment lane place L covers the sub-district under two call center's Equipment Control, is respectively call center's device A and call center's equipment B.As shown in figure 16, this method comprises:
Step 1601, mapping table, Location Area Identification and call center's equipment mapping table, user ID and the Location Area Identification mapping table of preservation station location marker and cell ID in call center's equipment of being correlated with in the sub-district that lane place L covers.
In this step, call center's equipment that the sub-district that lane place L covers is relevant is call center's device A and call center's equipment B.Usually, in call center's equipment, only dispose the mapping table of the sub-district under relevant position district sign and this call center's Equipment Control.That is to say, in the mapping table of the Location Area Identification of A equipment and cell ID, the general cell ID that does not need to dispose under the B Equipment Control in the mapping table of the Location Area Identification of B equipment and cell ID, does not need to dispose the cell ID under the A Equipment Control yet.In the present embodiment, because the same position district covers more than the sub-district under call center's Equipment Control of one, therefore in call center's equipment, further dispose relevant call center's equipment and the corresponding relation between the lane place.Wherein, call center's equipment can utilize this device address to represent, therefore, Location Area Identification and call center's equipment mapping table are Location Area Identification and device address, call center mapping table in the present embodiment, and the device address, call center can be the Destination Point Code or the IP address of this call center's equipment.When the corresponding relation of allocation position district sign and device address, call center, can not dispose self device address, call center, and the address that only disposes other call center's equipment of this lane place association.For example, in call center's device A, the address corresponding relation of allocation position district L and call center's equipment B, and the address corresponding relation of allocation position district L and call center's device A no longer; Equally, in call center B, the address corresponding relation of an allocation position district L and call center's device A.Described user ID can be IMSI or the TMSI of mobile subscriber in the gsm system for gsm system.
Suppose certain constantly, call center's device A is wanted calling user, then carries out following operation:
Step 1602, call center's device A are searched user ID and the Location Area Identification mapping table itself preserved according to user ID, obtain corresponding Location Area Identification.
Step 1603, call center's device A is obtained corresponding district information according to the Location Area Identification that obtains in the step 1602 from the Location Area Identification of configuration own and the mapping table of cell ID, and according to user totem information and the cell information that obtains paging is carried out in these sub-districts.
Step 1604, call center's device A is according to the Location Area Identification that obtains in the step 1602, obtaining other associated device address, call center of this Location Area Identification from Location Area Identification and device address, call center mapping table, also is the address of call center's equipment B.
Step 1605 judges whether to get access to the address of call center's equipment B, if do not get access to, and process ends then, otherwise, execution in step 1606-1607.
Step 1606 according to the address of call center's equipment B of obtaining, is carried out paging to call center's equipment B.
In this step, comprise location area information and user totem information in the paging information.
Step 1607, call center's equipment B is according to the position region identification information that receives, obtain corresponding district information from the station location marker of configuration own and the mapping table of cell ID, and paging is carried out in these sub-districts according to user totem information and the cell information that obtains.
In the present embodiment, step 1603 and 1604 is that order is carried out successively, and in fact, step 1603 and 1604 can random order be carried out or carry out simultaneously.
In the present embodiment, Location Area Identification and device address, call center mapping table can directly be configured in user ID and the Location Area Identification mapping table, and be perhaps, independent separately with user ID and Location Area Identification mapping table.When directly being configured to user ID and Location Area Identification mapping table, the mode that adopts can for: in user ID and Location Area Identification mapping table, increase a territory, device address, call center in this territory that this lane place is relevant is noted, like this, when obtaining Location Area Identification, can obtain this associated device address, call center of sign, correspondence position district according to user ID.
Adopt above-mentioned paging method, when a lane place covers the sub-district of a plurality of call centers Equipment Control, just can be implemented in the purpose that subscriber paging is carried out in all sub-districts under this lane place coverage.
The lane place collocation method that is provided by the above embodiment of the invention, method, paging method, location updating method and the system of Cell Broadcast CB lane place are as can be seen, it is a kind of when re-selecting cell that embodiments of the invention provide, the total solution of the frequent position replacement problem that occurs, make that the user can be according to actual needs, select to be suitable for most resident sub-district, thereby guarantee the access performance of terminal, and in densely populated city, under the little situation of radius of society, can reduce the updating of terminal position number of times that is in the lane place intersection.
