Abstract

A location updating method is provided, the current location area id information is stored in the terminal, the method comprises: the terminal judges if the cell to be selected of the terminal is in the current location area when it carries out the cell reselection, the location updating will not be carried out if it is, otherwise, the location area including the cell to be selected and the current resident cell will be the object location area and the location updating will be carried out. After carrying out the location updating by using the method of the embodiment of the present invention, even if the terminal at the border of the location area carries out cell reselection again and again in small range, the location updating will not be high frequency, thus it can freely select the most fit resident area to stay, and the terminal access capability is ensured.; A location updating system, a location area allocating method, a cell broadcasting location area method and a calling method are also provided in the embodiment of the present invention.

Description

Position updating method and system

Location updating method and system this application claims respectively on November 23rd, 2006, on December 12nd, 2006 submit Patent Office of the People's Republic of China, application number be respectively 200610144871.6 and 200610167132.9, denomination of invention be " location updating method and system " Chinese patent application priority, entire contents are hereby incorporated by reference in the application.Technical field

The present invention relates to mobile communication technology field, more particularly to location updating method and system.Background technology

In a communications system, countless cells can be included, these cells are the elementary cells for constituting mobile communications network, each one base station of cell correspondence a, base station typically 1 or multiple cells of configuration, each cell is responsible for the calling task in this cell.Call center, which calls one and is called, generally has two ways：If the position at called place is known by call center, directly position where this is called carries out paging；If the position at called place is not known by call center, and to ensure call, to called, must just carry out the whole network paging.

Specifically, in gsm communication system, many cells is had under an interchanger, work as mobile switching centre（When MSC) wanting calling terminal, if MSC knows the cell at the current place of the terminal, directly paging is carried out in the cell where the terminal；If MSC does not know the positional information of the terminal, paging is to if the terminal again, it is necessary to carry out paging to all cells under the MSC.

For above two paging way, two kinds of location updating modes of actual i.e. correspondence：

First, terminal all notifies MSC to carry out location updating, MSC is in paging in each cell reselection, it is possible to a current cell of the paging terminal.The advantage of this method is that paging range is minimum, and it is minimum that paging takes interface-free resources！But shortcoming it is also obvious that be exactly more new position size of message it is too big, signal resource consumption is big.

2nd, terminal is in each cell reselection, if the MSC at place does not change, and does not just notify MSC, and MSC carries out paging in paging to all cells under the MSC.The advantage of this method is that the number of times of location updating can be preferably minimized, and signal resource consumption is minimum！But have the disadvantage, paging range is too big, call the interface-free resources taken maximum！

For the shortcoming of above two scheme, a kind of solution of compromise is taken in existing GSM network Method, introduces the concept in position area, i.e. small under a MSC is distinguished into one or more position areas, multiple cells are included below in each position area, and these position areas are closely connected, but non-overlapping copies.So, when terminal changes in position, such as during cell reselection, whether the position area of new cell is changed and is judged, if the position area of new cell is identical with the position area where former cell, this cell reselection can not notify MSC;If the position area of new cell is different from the position area where former cell, launch position more new technological process, MSC is notified to there occurs that position area changes.Under this location updating mode, the mode of MSC call terminals mutually should be：When MSC paging terminals, paging is carried out to all cells under the position area where the terminal.

But for above-mentioned location updating method, there is problems with：Because position area is when dividing, closely coupled but non-overlapping copies, as shown in figure 1, position area L1 and position area L2, therefore the terminal having a common boundary in Liang Ge positions area, meeting moving back and forth because of position, or the fluctuation of radio signal, cause terminal at frequent re-selecting cell, can be with frequent updating position area, so as to trigger substantial amounts of location area updating message, i.e. location update message.In view of this consideration, during Terminal Design, a wealthy value is set to location area updating, the mobile subscriber in position area intersection is limited by this wealthy value and carries out frequently location area updating.For example, it can be directed to signal strength difference to set wealthy value, so, terminal is when the difference in signal strength of the signal intensity of cell in judging new position area Yu current persistent district is more than the wealthy value, ability execution position area update, will currently persistent district gravity treatment be new position area in this cell；Otherwise, i.e., terminal is when the difference in signal strength of the signal intensity of cell in judging new position area Yu current persistent district is less than the wealthy value, and terminal is without location area updating, i.e., not by current persistent district gravity treatment to this cell in the new position area.

Above by the limitation of wealthy value following negative effect can be brought in the mode that the terminal that Liang Ge positions area has a common boundary carries out frequently location area updating：

First, the terminal in position area boundary can not freely select most to be suitable for resident cell, particularly in the case where the signal of intersection each cell is all bad, terminal, which is unable to the best cell of unrestricted choice signal, can cause to mobile subscriber's paging success rate, and the percent of call completed of the terminal declines, and then influence the quality of network, interface-free resources are wasted, in today of interface-free resources growing tension, this waste to interface-free resources is extremely unadvisable.

Even if the 2, there is provided the wealthy value limits the frequently location updating of the terminal in position area intersection, but for densely populated city, in the case that radius of society is small, in position area intersection Terminal is still easy to cross over cell, so that terminal is easily met above-mentioned threshold value and causes the generation of location updating.The content of the invention

For the purpose of the present invention, technological means and advantage is more clearly understood, is developed simultaneously embodiment below in conjunction with accompanying drawing, the present invention is described in further detail.

The embodiment provides one kind at re-selecting cell, there is the total solution of frequent location updating problem so that user can select most to be suitable for resident cell, and will not cause frequent location updating according to actual needs.The solution includes the content of four aspects：

First, the embodiments of the invention provide a kind of position area collocation method so that the cell of certain region Nei Liangge adjacent positions area intersection is simultaneously in the two position areas.

Secondly as there is same cell while being located at Liang Ge positions area, therefore present invention also offers the method in cell broadcasting position area, multiple location area informations at certain cell are notified terminal by realization.

3rd, collocation method by above-mentioned position area, it may cause current paging policy can not paging user completely, for example, when some position area covers the cell under multiple calling center apparatus controls, wherein any one calling center apparatus can not notify the cell under other calling center apparatus controls to carry out paging to user.Then, the embodiments of the invention provide a kind of paging method, the problem of solving above-mentioned incomplete paging.

Finally, the method based on above-mentioned position area configuration mode and cell broadcasting position area, the embodiment of the present invention additionally provides a kind of location area updating method and system, when terminal carries out cell reselection, sentences Whether the cell to be selected of disconnected terminal is in present position-region, if so, then otherwise carrying out location updating without location updating.So, for the terminal positioned at certain position area boundary, while it is moving out position area, actually it is moved into the innerland in another the position area adjacent with the position area, so carry out after location updating, even if the boundary that the terminal continues to be wrapped up by present position-region in previous position area carries out cell reselection, as it is still located in present position-region, without causing frequently location area updating.

The embodiment in terms of aforementioned four is introduced separately below.

First, the position area collocation method in the embodiment of the present invention is introduced.This method includes：The heart at least configures Liang Ge positions area in a call, and at least one cell is configured in first position area and second place area simultaneously；By at least one cell configuration in the area of first position, and outside the area of the second place；By at least one cell configuration in the area of the second place, and outside the area of first position.Certainly during actual disposition, multiple position areas for meeting above-mentioned condition can be configured in the range of covering in one or more call centers in a communication network, constitutes various position section models.

During allocation position area, it is related to several concepts, is non-overlap mode contact, overlap mode contact, wrapped border, bound edge and mutual bound edge respectively, these concepts are described below：

First, Liang Ge positions area is referred to non-overlap mode contact, and there is border overlay in Liang Ge positions area, but is in simultaneously in the two position areas in the absence of any cell.

2nd, Liang Ge positions area is contacted in an overlapping arrangement refers to, at least there is a cell and is in simultaneously in the two position areas.

3rd, border is wrapped and referred to, between two cells of La border in Lb, then La this segment boundary is wrapped up by Lb.

4th, position area bound edge refers to that the part or all of border in another position area is wrapped up in position area.When position area La parcel locations area Lb border：Position area La and Lb are contacted in an overlapping arrangement, and there is a cell in position area La outside position area Lb.Also referred to as La bags Lb side.

5th, the mutual bound edges of La and Lb refer to：La bags Lb side, and Lb bags La side.

Intuitively illustrate above-mentioned several concepts by three figures separately below.These three figures are three kinds of embodiments of the invention described above position area collocation method respectively.

Fig. 2 is the first simple rectangle position section model, as shown in Figure 2： U covers cell C01 ~ C08, C11 ~ C19, C21 ~ C28, C31 ~ C39, C41 ~ C48, C51-C59, etc., and these cells possess LI position region identification informations；L2 covers cell C31 ~ C39, C41 ~ C48, C51 ~ C59, C61 ~ C68, C71 ~ C79, C81 ~ C88, etc..These cells possess L2 position region identification informations.Wherein, cell C31 ~ C39, C41 ~ C48, C51 ~ C59 etc. is in the two position areas of L1 and L2 simultaneously.These cells being in simultaneously in the area of Liang Ge positions possess L1 and L2 position region identification information respectively.

In fig. 2, L1 and L2 are exactly to contact in an overlapping arrangement；Actually it is also mutual bound edge, here, L1 has only wrapped up L2 a part of border, and L2 also only includes L1 segment boundary.

Fig. 3 is a kind of mono- Round shaped positions section models of Jian.As shown in Figure 3：

L1 covers the cell in L1 external boundaries, and these cells possess L1 position region identification informations；L2 is covered beyond L2 inner boundaries, the cell within L2 external boundaries, and these cells possess L2 position region identification informations.Wherein, the cell within L1 external boundaries, beyond L2 inner boundaries is simultaneously in the two position areas of L1 and L2, and these cells being in simultaneously in the area of Liang Ge positions possess L 1 and L2 position region identification information respectively.

In figure 3, L1 and L2 are also to contact in an overlapping arrangement；Actually it is also mutual bound edge.Here, L2 has wrapped up L1 all borders, and L1 has wrapped up L2 all inner boundaries.In practical application, a small cities and towns can be covered with L1, and the suburb in this cities and towns is covered with L2.

Fig. 4 is second of rectangle position section model.As shown in Figure 4：

U covers cell C01 ~ C08, C12 ~ C19, C21 ~ C28, C32 ~ C39, C41 ~ C48 etc., and these cells possess LI position region identification informations；L2 covers cell C21 ~ C28, C31 ~ C38, C41 ~ C48, C51 ~ C58, C61 ~ C68 etc., and these cells possess position region identification information；L3 covers cell C51 ~ C59, C61 ~ C68, C71 ~ C79, C81 ~ C88 etc., and these cells possess L3 position region identification informations.Wherein, cell C21 ~ C28, C32 ~ C38, C41 ~ C48 etc. is simultaneously in the two position areas of L1 and L2, and these cells possess L1 and L2 position region identification information respectively；Cell C51 ~ C58, C61 ~ C68 etc. is simultaneously in the two position areas of L2 and L3, and these cells possess L2 and L3 position region identification information respectively.

In Fig. 4, L1 and L3 is exactly to be contacted with non-overlap mode, and L1 and L2 are to contact in an overlapping arrangement, and L2 and L3 are also to contact in an overlapping arrangement.

Similarly, in Figure 5, any two position area in the area of tri- positions of Ll, L2 and L3 is with weight Folded mode is contacted.

Above three figure is the embodiment of position area collocation method in the embodiment of the present invention.The configuration in certain position area is not limited only to above-mentioned three kinds of modes.The multi-level positions section model of the position area collocation method of the present invention is described below.

For the covering of strip, such as one long and narrow island, when position area can cover the width in the area, two layers of intensive overlay model such as Fig. 4 can be used, here it is possible to according to actual conditions, by position area L2 to moving down or to moving up.In intensive overlay model, centre one position area in connected three positions area exists overlapping with both sides Liang Ge positions area, and both sides Liang Ge positions area is contacted with non-overlap mode.

Equally, for the covering of strip, it would however also be possible to employ such as Fig. 6 two layers of relaxation overlay model.In relaxation overlay model, centre one position area in connected three positions area exists overlapping with both sides Liang Ge positions area, and both sides Liang Ge positions area is not in contact with.

, can be using three layers of intensive position section model shown in Fig. 7, it would however also be possible to employ three layers of slack position section model shown in Fig. 8 for the covering in big region.

As shown in Fig. 7, thick line hexagon, thick dashed line hexagon and fine rule hexagon each independently can be covered continuously, this three floor position area interlocks covering, three positions area in the same direction, thick line hexagon both sides are thick dashed line hexagon and fine rule hexagon respectively, thick dashed line hexagon both sides are thick line hexagon and fine rule hexagon respectively, and fine rule hexagon both sides are thick dashed line hexagon and thick line hexagon respectively.In addition to the border of whole region, the border in any one position area is all wrapped up by the position area of other floor.Here, a cell only needs to be in most three positions areas simultaneously.

As shown in Fig. 8, thick line hexagon, thick dashed line hexagon and fine rule hexagon each independently can not continuously cover whole region, and such as figure mode is staggeredly covered three simultaneously, and the covering to whole region can be completed together.In addition to the border of whole region, the border in any one position area is all wrapped up by the position area of other floor.Here, a cell only needs to be in most three positions areas simultaneously.

Equally, can be using four layers of intensive position section model shown in Fig. 9, it would however also be possible to employ four layers of slack position section model shown in Figure 10 for the covering in big region.

As shown in figure 9, first layer position area includes： ABFG、 CDHL KLPQ、 MNRS;Second layer position area includes： BCGH、 DEI J, LMQR、 NOST;Third layer position area includes： FGKL、 HIMN、 PQUV、 RSWX;4th floor position area includes： GHLM、 IJ O、 QRVW、 STXY. Each floor position area can continuously cover a panel region, and this four floor position area interlocks covering, cover whole region.In addition to the border of whole region, the border in any one position area is all wrapped up by the position area of other floor.Here, a cell only needs to be in most four positions areas simultaneously.

As shown in Figure 10, first layer position area includes four pecked line quadrangle positions area, second layer position area includes two line segment dotted line quadrangle positions area, and third layer position area includes two fine rule quadrangle positions area, and the 4th floor position area includes thick line quadrangle position area.Each floor position area can not all complete continuous covering, unless only one of which position area of a certain floor position area.Such as figure mode is staggeredly covered simultaneously in four floor position areas, and the covering to whole region can be completed together.In addition to the border of whole region, the border in any one position area is all wrapped up by the position area of other floor.Here, a cell only needs to be in most four positions areas simultaneously.

Intensive position section model can reduce the possibility on terminal cross Liang Ge non-overlapping positions area border with more degree, namely step out the possibility on position area border, but in a call in the minds of, position area data configuration can be corresponding more.

For the relatively intensive position section model of slack position section model, the possibility increase on position area border is stepped out in the possibility increase on terminal cross Liang Ge non-overlapping positions area border, but position area data configuration can accordingly lack in the heart in a call.

, can be with the above-mentioned various position areas overlay model of integrated application, so as to reach the double excellent of engineering and network quality when carrying out the covering of position area than broader region for one among practical application.

The multi-level positions area of above-mentioned introduction is two layers, the model of three floor and four floor, certainly according to bound edge technology, can also form the position area configuration of more layers, principle is identical, is just repeated no more here.

The embodiment of the above-mentioned position area collocation method for being the embodiment of the present invention.After these position area collocation methods, it be may be in for same cell in multiple position areas, mode according to current cell broadcast messages, it is impossible to which multiple position areas at the cell are all broadcast to user, therefore the embodiment of the present invention additionally provides a kind of Cell Broadcast CB method.This method is specifically included：The identification information in multiple position areas at the cell is preserved in the base station belonging to cell；Cell broadcasting position area identification information is disposably or several times by the identification information broadcast in multiple position areas at the cell to terminal by base station.

The specific implementation of the above method can be divided into two big types：First, the identification information in the position area at this cell is only broadcasted in the broadcast message of cell, terminal is respective wide by receiving multiple cells Broadcast the identification information that message obtains the position area at these cells；2nd, except the position region identification information broadcasted at this cell is in the broadcast message of cell, also further broadcast the position region identification information at its neighbor cell, terminal can obtain the cell and its position region identification information at neighbor cell by receiving the broadcast message of the cell.Both modes are described separately below.

First, the identification information in the position area at this cell is only broadcasted in the broadcast message of cell.The mode of the corresponding Location Area Identification of cell is preserved in a base station.For example, the identification information of the cell managed in a base station according to the base station, saves multiple position region identification informations belonging to each cell in the base station, shown in reference picture 4, C52, C53 and C62 belong to three cells of same BTS management, as shown in table 1.

Table 1

During Cell Broadcast CB, multiple position region identification informations of the base station from the cell ID as shown in table 1 and position region identification information mapping table according at cell ID obtains the cell, and be broadcasted by the way that cell broadcast messages are one or many, so, terminal can obtain the identification information in multiple position areas at a cell by cell broadcast messages.

It is of course also possible to preserve multiple position region identification informations belonging to each cell with such as table 2 below：

Table 2

It should be noted that when preserving d, area's mark and the mapping table of position region identification information, Both can be such as Tables 1 and 2-sample, the identification information of the cell managed according to the base station, multiple position region identification informations belonging to each cell are saved in the base station, it can also carry out in another form, i.e., in a base station according to the identification information in position area, the cell identity information for being managed the base station in the base station is saved；Such as table 3:

Table 3

Obviously, from table 3, multiple position region identification informations at the cell can also be obtained according to cell ID.

In fact, table 2 is referred to as preserving d, area's mark according to position region identification information.

Certainly, base station is when preserving the position region identification information at a cell, it can also be carried out using other manner, for example, the other parameters of the identification information in the position area at a cell and the cell are saved in a data file together.

When the position region identification information at a cell is more than one, during cell broadcasting position area identification information, can once it be broadcasted, for example, Extended Cell broadcast message length, increase broadcast location area information content, be once broadcasted the position region identification information at the cell.

Multiple position region identification informations at the cell can also be broadcasted by cell by repeatedly broadcasting.It is for instance possible to use repeating query mode, once broadcasts a position region identification information.For example, for cell C62 in upper table, position region identification information at the cell is L2 and L3, L2 position region identification information can be broadcasted the cell by broadcast for the first time, second of broadcast can be by L3 position region identification information, then, then L2 position region identification information, such broadcast (sites) in turn are broadcasted.In practical application, cell can intercut other cell parameter informations between the message of broadcast location area information twice.

For example, terminal obtains one or more position region identification informations at the cell from the cell broadcast information；Judge whether include the identification information in the position area in one or more position region identification informations at the cell obtained, if, then judging the cell is in the position area, otherwise, judges that the cell is not in the position area. Terminal obtains the mode of position region identification information that two cells are co-located on：Terminal obtains one or more position region identification informations residing for first community as first community position region identification information from first community broadcast message, and one or more position region identification informations at second community are obtained from second community broadcast message and are used as second community position region identification information；Then, terminal relatively states first community position region identification information and the second community position region identification information, identical position region identification information in two groups of position region identification informations is therefrom obtained, the position region identification information that first community and second community are co-located on then is can be obtained by.

Usually, each cell only broadcasts the identification information in all position areas at oneself, so, terminal can obtain the identification information in all position areas at respective cell from the broadcast message of each cell, in this case, terminal obtains the identification information in the position area at current persistent district by the broadcast message of current persistent district, and the identification information in each position area at its neighbor cell is obtained by the identification information of its neighbor cell.

2nd, the position region identification information at this cell and this cell neighbor cell is included in cell broadcast messages.

Certainly, except the identification information sunset for including the position area at this cell is foretold in the message of Cell Broadcast CB, it can further include the identification information in the position area at its neighbor cell, for example, the identification information in the relevant position area in the base station belonging to cell further according at the identification information of the identification information of the cell and its neighbor cell preserves the cell neighbor cell, or, the identification information in each position area at its neighbor cell is preserved in the cell configuration data, as shown in Figure 4, there is C52 cell C62 neighbor cell, C53, C61, C63, 6 cells such as C72 and C73, so, position region identification information data at the neighbor cell preserved in cell C62 configuration data can be described with such as table 4 below：

Table 4

Neighbor cell home position area is identified

C52 L2, L3

C53 L2, L3

C61 L2, L3

C63 L2, L3

C72 L3

If saving the position region identification information at self-administered multiple cells in base station, and its position region identification information at neighbor cell, so, the domain of a current cell identification information can be increased in table 4, for example, C52, C53 and C62 belong to three cells of same BTS management, as described by table 5 below：

Table 5

Configuration based on table 4 or table 5, the base station may further include in cell broadcast messages the cell neighbor cell mark and the corresponding neighbor cell at relevant position area identification information.In this case, terminal need to can only be obtained currently by the broadcast message of current persistent district Each position region identification information at persistent district and its neighbor cell.But it can so increase the information content of Cell Broadcast CB.

The specific implementation for illustrating above two mode as exemplified by Location Area Identification is numbered using position area.First, preferably, the identification information in all position areas at the cell is preserved in cell configuration, so as to when cell is broadcasted, include the position area numbering at the cell of configuration in broadcast message, the position area is numbered possibly more than one, and multiple position areas are corresponded to respectively.Terminal can obtain the position area numbering at position area numbering and the neighbor cell at current persistent district from the broadcast message of cell.When carrying out Cell Broadcast CB, all position areas numbering at this cell disposably or several times can be broadcasted by base station, and terminal is by receiving the position area number information at broadcast singal one cell of acquisition of cell.

Specifically, terminal, which obtains current area and the mode of the position area numbering at neighbor cell, to be：

A, terminal can obtain the identification information that neighbor cell is may further include in the position area numbering at current area, and neighbor cell relevant parameter information, the parameter information from the broadcast message of current area；Terminal can receive neighbor cell signal according to the parameter information of the neighbor cell of acquisition, and the position area numbering of neighbor cell broadcast is obtained from these signals, i.e., the position area numbering at neighbor cell.

B, terminal can directly intercept the broadcast singal of neighbor cell using random frequency modulation or other manner, the parameter information of neighbor cell is obtained from the broadcast message of current area without taking, so as to intercept the mode of neighbor cell broadcast singal according to the parameter information.But, the mode that this directly random frequency modulation or other manner intercept neighbor cell broadcast singal may consume larger to terminal.

2nd, the numbering in all position areas at the cell had both been preserved in cell configuration, the numbering in each position area at the neighbor cell of the cell is preserved again.For example, position area numbering at neighbor cell can be configured in the configuration data of current persistent district, namely, the identification information in the relevant position area at the cell neighbor cell is further preserved in the base station belonging to current persistent district, so as to when being broadcasted in current area, in broadcast message in addition to the numbering of the position area at current area is included, the position area numbering at neighbor cell is still further comprised.Terminal obtains the position area number information at neighbor cell from the broadcast singal of current area.But it can so increase the broadcast message amount of current area. In above two mode, position region identification information that can also further in the call center belonging to cell or base station controller according at cell ID preserves the cell, or, the cell identity information belonged under the call center or base station controller control that the position area includes is saved according to position region identification information, namely, pre-save the position region identification information at cell and the corresponding relation of the cell identity information, the position region identification information at cell that base station is preserved, can be on base station after electricity, obtained from call center or base station controller.For example, base station sends the request message for obtaining the position region identification information at cell to the call center or base station controller, cell identity information is carried in message, the call center or base station controller are upon receiving the request, position region identification information according at cell identity information from the cell of the preservation with obtain the cell in the corresponding relation data of the cell ID at position region identification information, and these position region identification informations of acquisition are sent to base station.

But among current most of applications, the corresponding relation of position region identification information and the cell ID at cell directly can in a base station be configured in network design by engineer.

By the above-mentioned means, terminal can just know corresponding configuration mode of the call center to position area.On the basis of above-mentioned position area collocation method and cell broadcasting position area method, the location updating method of the embodiment of the present invention and the embodiment of system is described below.

Figure 11 is the overview flow chart of location updating method embodiment of the present invention.As shown in figure 11, this method includes：

Step 1101, heart allocation position area in a call, at least provided with first position area and second place area, a cell configuration wherein be will have at least into while in first position area and second place area, by at least one cell configuration into the area of first position and outside the area of the second place, by least one cell configuration into the area of the second place and outside the area of first position.

The step completes the configuration in two mutual bound edge positions area.

In this step, the mode for carrying out the configuration of position area is identical with foregoing position area configuration mode.The call center can be a call center resource pond, you can with including one or more calling center apparatus.

Each calling center apparatus can be established a communications link with least one cell, and the cell that the cell write to each other is the calling center apparatus is established with the calling center apparatus.

The position area can include one or more cells of a calling center apparatus, can also wrap Include one or more cells of multiple calling center apparatus.

For example, for GSM communication networks, a calling center apparatus can be a MSC/VLR equipment, call center can be the resource pool of one or more MSC/VLR equipment.

Step 1102, the position region identification information at itself is broadcast to terminal by cell.

Step 1103, when terminal carries out cell reselection, judge whether the cell to be selected of terminal is in present position-region, if so, then performing step 1104, otherwise perform step 1105.

Step 1104, without location updating and this flow is terminated.

Step 1105, it will determine that position area, as target location area, carries out location updating in one or more position areas residing for cell to be selected.

In step 1101, first position area and second place area are actually the Liang Ge positions area of mutual bound edge.

In step 1105, after being updated successfully in position, it may further include execution and the cell to be selected be set to persistent district operation, and the target location area is set to present position-region.

In step 1105, arbitrarily or at random it can determine that position area is used as target location area directly from one or more position area at cell to be selected；Or, it would however also be possible to employ certain strategy determines target location area；Or, the number information in the position area at cell to be selected can also first be obtained, whether the number for judging the position area at cell to be selected is more than one, if, then target location area is determined from the common location area of cell to be selected and current persistent district, otherwise using the position area at cell to be selected as target location area, location updating is carried out.

In step 1105, it can be that target location area identification information is sent into call center to carry out location updating, call center is received after the target location area identification information of terminal transmission, and the present position-region of the terminal is set into the position area specified by the target location area identification information of reception.After call center is updated successfully in position, a success message can be sent to terminal, terminal preserves target location area identification information as present position-region identification information.

In the embodiment of the present invention, judge that the mode whether a cell belongs to position area can be：Terminal obtains one or more position region identification informations at the cell from the cell broadcast information；Judge whether include the identification information in the position area in one or more position region identification informations at the cell obtained, if it is, judging that the cell is in the position area, otherwise, judge that the cell is not in the position area. Illustrating above-mentioned judgment mode is, it is assumed that terminal preserves present position-region identification information, in addition, terminal gets one or more position region identification informations at cell to be selected from cell broadcast information to be selected, then judge whether cell to be selected is in present position-region and refer to：Judge whether include present position-region identification information in one or more position region identification informations at the cell to be selected obtained, if, then judging cell to be selected is in present position-region, otherwise, judges that cell to be selected is not in present position-region.

When terminal judges that oneself does not preserve present position-region identification information, one or more position region identification informations residing for current persistent district are obtained from current persistent district broadcast message, one of position region identification information is saved as into present position-region identification information, and initiates location updating.

The mode that terminal obtains the position region identification information of current persistent district and cell common point to be selected can be：Terminal can obtain one or more position region identification informations residing for current persistent district as current persistent district position region identification information from current persistent district broadcast message, and obtain from cell broadcast information to be selected one or more position region identification informations residing for cell to be selected as subdistrict position area to be selected identification information；Terminal can therefrom obtain the position region identification information that cell to be selected and current persistent district are co-located on by relatively current persistent district position region identification information and subdistrict position area to be selected identification information.

Here position region identification information can be Location Area Identification in itself or position region sequence number, can be Location Area Identification LAI (Location Area Identification) or Location Area Code LAC (Location Area Code) for example for the Location Area Identification of the present invention is for GSM systems.

Figure 12 is the overall construction drawing of updating of terminal position system embodiment of the present invention.As shown in figure 12, the system includes：Call center 1210, base station 1220 and terminal 1230.

Within the system, call center 1210, for allocation position area, at least include first position area and second place area, wherein, at least one cell simultaneously in the first position area and second place area, in the area of first position at least one cell outside the area of the second place, and in the area of the second place at least one cell outside the area of first position；The target location area identification information of receiving terminal transmission is additionally operable to, location updating is carried out.

Base station 1220, for obtaining the location of the respective cell sent area's identification information from call center 1210, and is distributed to terminal 1230 by cell broadcast messages.

Terminal 1230, for receiving at the respective cell that base station 1220 is issued in Cell Broadcast CB Position region identification information, when terminal carries out cell reselection, judges whether the cell to be selected of terminal is in present position-region, if so, then without location updating, otherwise, target location area is determined from the location of cell to be selected area, location updating is carried out.

In said system structure, it is not what is be joined directly together between terminal 1230 and call center 1210, therebetween it is connected by other network equipments, therefore the annexation of the two is represented by dashed line, but final goal Location Area Identification can be sent to call center 1210.

Above-mentioned is the overview of the embodiment of the present invention, passes through above-mentioned position area bound edge technology so that when carrying out cell reselection, can select most to be suitable for resident cell as needed.

Specifically, by taking Fig. 2 as an example, position area L1 and L2 division are carried out using mutual bound edge mode.Because L1 wraps up L2 border, L2 wraps up L1 border, so that reducing the boundary that mobile terminal mutually wraps up in Liang Ge positions area carries out caused terminal current location area variability during location updating.

Because position area is handled by bound edge, so, when the terminal in-position area L1 position area border wrapped up by L2, in fact, the also innerland with regard to in-position area L2, in this case, when location updating is to L2, due to the border on innerland of the terminal in L2, rather than L2, therefore, avoid terminal and be in the location updating phenomenon repeatedly triggered during position area border.

It is in simultaneously in position area L1 and L2 in the cell of L1 and L2 overlappings, L1 and L2 position region identification information can be included in these community configured informations；In the broadcast singal of these cells, L1 and L2 position region identification information can also be included.

During updating of terminal position, selected position area can be registered in the call center of network, for example in gsm networks, Location Area Identification can be sent to progress position area registration in VLR.When terminal re-selecting cell, when judging that cell to be selected is not belonging to present position-region, launch position updates, by location updating to new position area.Preferable mode is that terminal judges that cell to be selected and current area whether there is common position area, if it does, just by location updating to this common position area.

The position area contacted for script with non-overlap mode, such as the L1 and L3 in Fig. 4, the present invention program is the position area for allowing the two to be contacted with non-overlap mode in adjacent, or boundary, carry out mutual bound edge, it is set to contact in an overlapping arrangement as shown in Figure 2, the mutual bound edge of L1 and L2 therein.

Include the location of cell area identification information in community configured information, in the message of the Cell Broadcast CB, include the location of cell of configuration area identification information, such as position area is numbered, so as to realize that cell notifies position Division result the purpose of terminal.The message of Cell Broadcast CB includes Position area number possibly more than one, respectively correspond to multiple position areas.

The method of above-mentioned cell broadcasting position area identification information can use foregoing embodiment, and terminal is that would know that the position area configuration information that call center is carried out, i.e., the location of one cell area's identification information.Then, terminal judges cell to be selected before re-selecting cell, first（Cij) the position area numbering registered in location area numbering with the presence or absence of terminal in network side, i.e. present position-region is numbered, if it is present it is Cij that terminal, which selects current persistent district,;If the position area numbering that terminal is registered in network side is not present in the location of Cij areas numbering, terminal launch position more new technological process, by the location of location updating to Cij area.Preferably scheme is if Cij and current persistent district（When Cdock) there is the location of common area, the selection of current persistent district, as present position-region, and after being updated successfully in position, is Cij by the location of selection Cij and Cdock is common area.

For example when terminal judges that cell Cij signal quality is better than current persistent district Cdock signal quality, it can start and above-mentioned reselect cell flow.

Above-mentioned terminal when position area L1 and L2 intersection carries out cell reselection, if it find that cell Cij to be selected be in oneself it is current in a call in the heart the position area of registration when, then not launch position more new technological process, and be only Cij by cell reselection.If it find that cell to be selected is not belonging to oneself current position area, then launch position more new technological process.Such as present position-region is position area L1, and terminal saves in a call the position region identification information of registration in the heart here.

Terminal is in launch position more new technological process, and preferable processing mode is first to judge whether Cij and Cdock is co-located on some or some position areas, if it is selects the position area in the location of common area to be used as present position-region.

Illustrate that said process is by taking Fig. 2 as an example：It is assumed that present position-region is LI, Cdock is C56, then when Cij is C55 or C57 or C45 or C46, terminal is at re-selecting cell, without location updating；When Cij is C65 or C66, because C65 or C66 is not belonging to position area L1, therefore, terminal will also carry out location updating at re-selecting cell.So that Cij is C66 as an example, terminal selects L2 as the target location area of renewal in location updating.Certainly, common C66 and C56 position area is also L2 here.

Under the position section model shown in Fig. 2, terminal from cell C56 gravity treatments to cell C66 and updates present position-region to after L2, when terminal because the reason for signal reason or user move, when again from cell C66 gravity treatments to cell C56, terminal judges that C56 falls within L2, therefore, line position would not be entered again Put and have updated.So, the problem of terminal would not occur frequently executing location updating because of the border wrapped up by L2 in L1.

Accordingly, when terminal current location area is L2, after being updated from cell C33 gravity treatments to cell C22 and by present position-region to L1, when terminal because the reason for signal reason or user move, when again from cell C22 gravity treatments to cell C33, terminal judges that C33 falls within L1, therefore, would not carry out location updating.So, the problem of terminal would not occur frequently executing location updating because of the border wrapped up by L1 in L2.

Certainly, in practical application, terminal re-selecting cell is not just using cell signal quality as unique criterion, and terminal is also conceivable to the other factorses such as busy cells degree, just repeats no more here.

Therefore the present invention can be efficiently solved in the prior art, when terminal is rocked on certain position area border, caused frequent location updating problem.

As it was previously stated, it is determined that having four kinds of situations during the area of target location in the embodiment of the present invention：A, the determination target location area from current area and the position area of cell common point to be selected；B, first judge the location of cell to be selected area number, then determine target location area；C, directly random or any-mode determine position area；D, the position relationship in each position area according to terminal and residing for cell to be selected, determine position area.Three embodiments are named, are illustrated respectively under tri- kinds of combined situations of ab, ac, ad, the embodiment of location updating method of the invention.

Location updating method embodiment one：

In the present embodiment, it is determined that during the area of target location, first determining whether the number in the location of cell to be selected area, then determining target location area according to the number.

Figure 13 is the particular flow sheet of Position Updating embodiment of the method one of the present invention.As shown in figure 13, this method includes：

Step 1301, the heart in a call, at least provided with the position area of two mutual bound edges.

The Liang Ge positions area of such as setting is first position area and second place area, by at least one cell configuration into while in the first position area and the second place area, by at least one cell configuration into the first position area and outside the second place area, by least one cell configuration into the area of the second place and outside the first position area.In this step, it is of course possible to carry out the configuration in position area with reference to the position area allocation models of foregoing various bound edges.

Step 1302, cell by the location of area identification information broadcast itself to terminal. In this step, the mode that the base station where cell obtains the location of this cell area identification information can be：The identification information in one or more position areas residing for call center's configuration cell, when being powered up in base station, obtains the location of cell area identification information, and the location of cell area identification information is configured in base station from call center；Or, in initial networking, the location of cell area identification information is configured in base station.For GSM network, the call center can be MSC/VLR.Accordingly, can also be by base station controller for gsm system（BSC) identification information in one or more position areas residing for configuration cell, when electric on base station, can obtain the location of cell area identification information from BSC.

The concrete mode that position region identification information is broadcast to terminal is by base station：Further comprise the identification information in one or more position areas residing for the cell in cell broadcast information, these position region identification informations disposably or are several times broadcast to terminal by base station.The method embodiment of which namely cell broadcasting position area provided in an embodiment of the present invention identification information.

Step 1303, when terminal carries out cell reselection, judge whether the cell to be selected of terminal is in present position-region, if so, then performing step 1304, otherwise perform step 1305.

Step 1304, without location updating and this flow is terminated.

Step 1305, call center judges whether the number in the location of cell to be selected area is one, if it is, performing step 1306, otherwise, performs step 1307.

Step 1306, using this position area residing for cell to be selected as target location area, location updating is carried out, and terminate this flow.

Step 1307, target location area is determined in the position area being co-located on from cell to be selected and current persistent district, location updating is carried out.

In step 1306, when the location of cell to be selected area be one when, can also according to terminal re-selecting cell in existing GSM network processing mode, perform：Judge whether the signal intensity of cell to be selected reaches default wealthy value with the signal strength difference of current persistent district, if reaching the default wealthy value, then using cell to be selected as persistent district, and location updating is carried out using the position area of the cell to be selected as target location area；Otherwise, do not perform cell to be selected as persistent district, determination target location area and follow-up location update operations are not performed yet.

It is preferred that when the number in the location of cell to be selected area is in one, it can be determined that whether current persistent district is in the position area of cell to be selected, if it is, can be directly by the position area It is used as target location area.If it is judged that current persistent district is not in the position area of cell to be selected, then according still further to the processing mode of terminal re-selecting cell in existing GSM network, judge whether the signal intensity of cell to be selected reaches default wealthy value with the signal strength difference of current persistent district, if reaching the default wealthy value, then using cell to be selected as persistent district, and location updating is carried out using the position area of the cell to be selected as target location area；Otherwise, do not perform cell to be selected as persistent district, determination target location area and follow-up location update operations are not performed yet.

In step 1306, it can determine whether whether current persistent district is in the position area of cell to be selected, if be in, regard the position area of the cell to be selected as target location area.By taking the position section model shown in Fig. 2 as an example：It is assumed that current persistent district is C32, present position-region is L2, and cell to be selected is C22, the location of C22 areas number is 1, i.e. position area L1, it is clear that, C32 is in C22 position area L1, can regard L1 as target location area here.

Among actual, when there is Liang Ge positions area and contacted with non-overlap mode, it is possible that judging the situation that current persistent district is not in the position area of cell to be selected, at this moment, it is referred to the residence reselecting of GSM prior arts to carry out cell reselection.By taking the position section model shown in Fig. 4 as an example, ^^ determines present position-region for L1, current area is C48, cell to be selected is C59, here, the location of C59 areas only have this position area of L3, and current persistent district C48 is not in L3, in this manner it is possible to be handled with reference to the existing cell reselection modes of GSM.For example：A wealthy value of difference in signal strength can be preset, judge whether the signal intensity of cell to be selected reaches default threshold value with the signal strength difference of current persistent district, if reaching the default threshold value, then it regard the position area of the cell to be selected as target location area, otherwise, determination target location area and follow-up location update operations are not performed.

Here, terminal obtains one or more position region identification informations residing for current persistent district from current persistent district broadcast message；Judging whether current persistent district is in this position area of cell to be selected can be：Judge whether include the identification information in this position area of the cell to be selected in one or more position region identification informations residing for the current persistent district obtained, if, then judging current persistent district is in this position area of cell to be selected, otherwise, judge that current persistent district is not in this position area of cell to be selected.

In step 1306, can also be without judging the operation whether current persistent district is in the position area of cell to be selected when it is one to judge the location of cell to be selected area, but directly will The position area of the cell to be selected is used as target location area.Such case is especially effective when each position area is only contacted in an overlapping arrangement with other positions area in a communication network.It is of course also possible to be handled with reference to the existing cell reselection modes of above-mentioned GSM, just repeat no more here.

In step 1307, before target location area is determined from the common location area of cell to be selected and current persistent district, it can determine whether that cell to be selected whether there is the position area of common point with current persistent district, if there is, the operation in target location area is determined in then performing the common location area from cell to be selected and current persistent district, otherwise, one in multiple position areas residing for cell to be selected is selected as target location area, for example, any or random selection one position area is used as target location area as one of target location area from multiple position areas residing for cell to be selected.

In step 1307, when cell to be selected and the position area only one of which of current persistent district institute common point, directly it regard the position area as target location area.By taking the position section model shown in Fig. 4 as an example：It is assumed that current persistent district is C43, present position-region is L1, and cell to be selected is C53, and the location of C53 area's numbers are 2, i.e. position area L2 and L3, it is clear that the position area that C32 and C22 are co-located on is L2.Here it regard L2 as target location area.

In step 1307, when the position area being co-located on when cell to be selected and current persistent district is more than one, one in multiple position areas that cell to be selected is co-located on current persistent district is selected as target location area.For example, any from multiple position areas that the two cells are co-located on or random selection one position area is as target location area.By taking the position section model shown in Fig. 5 as an example：It is assumed that current persistent district Cdock is C53, present position-region is L1, cell to be selected is C62, the position area number that C62 and C53 is co-located on is 2, that is position area L2 and L3, in this case, can any from C53 and C62 or random selection one position area be used as target location area, for example, selection L3 is used as target location area.

In the step 1307 of the present embodiment, when determining target location area, selected in the position area being co-located on from cell to be selected and current persistent district.In fact, at random or position area can also be arbitrarily determined as target location area from multiple position areas residing for cell to be selected, it must not necessarily be selected in the position area that cell to be selected and current persistent district are co-located on.

In the present embodiment, after location updating success, it may further include terminal and preserved the cell to be selected as persistent district, and using target location area identification information as present position-region identification information.For example, location updating success message is sent to terminal by call center, terminal passes through the message Know whether location updating succeeds.

The idiographic flow of the location updating method of the above-mentioned terminal provided for the present embodiment, the present embodiment additionally provides a kind of concrete structure of the position updating system of terminal, can be used for implementing above-mentioned location updating method.Figure 14 is the concrete structure diagram of the position updating system of terminal in the embodiment of the present invention one.As shown in figure 14, the system includes：Call center 1210, base station 1220 and terminal 1230.Wherein, terminal 1230 includes receiving module 1231, main control module 1232 and sending module 1233.

Within the system, call center 1210, for allocation position area, at least include first position area and second place area, and at least one cell is in first position area and second place area simultaneously, at least one cell is outside the area of the second place in the area of first position, and in the area of the second place at least one cell outside the area of first position；It is additionally operable to receive the target location area mark that the terminal is sent, carries out location updating.

Base station 1220, for obtaining the location of the self-administered cell sent area's identification information from call center 1210, and is distributed to terminal 1230 by cell broadcast messages.

In terminal 1230, the broadcast message, for receiving base station 1220 in cell broadcast messages, within the message including all Location Area Identification belonging to base station, and is sent to main control module 1232 by receiving module 1231.Main control module 1232, come from the cell broadcast messages of the forwarding of receiving module 1231 for receiving, signal(l)ing condition according to the cell of each in message etc. determines to carry out cell reselection, and whether determined whether to carry out location updating in present position-region according to cell to be selected, when it is determined that carrying out location updating, it regard the position area belonging to cell to be selected and current persistent district are common as target location area, notice sending module 1233, progress location updating.Sending module 1233, call center 1210 is sent to for the target location area for being received from main control module 1232 to be identified.

In the embodiment of said system, it is not what is be joined directly together between the sending module 1233 of terminal 1230 and call center 1210, therebetween it is connected by other network equipments, but final goal Location Area Identification can be sent to call center 1210.

When carrying out location updating with system according to the method described above, for the terminal in certain position area boundary, when it carries out cell reselection and after initiate location updating, due to being cell to be selected and the common affiliated position area in current persistent district by its location area updating, therefore, even if the problems such as terminal is due to signal or service quality is when original persistent district is gone back in gravity treatment again, also without carrying out location updating again, it is to avoid the problem of terminal of position area boundary is due to the cell position area frequent updating that gravity treatment is caused repeatedly.By The problem of in the absence of position area frequent updating, the location updating of wealthy value limiting terminal need not be set naturally so that terminal can freely be selected most to be suitable for resident cell according to network condition.

Whether it is the operation of one it is determined that during the area of target location, first can not also perform the number that judges the location of cell to be selected area among actual, but the determination target location area directly from the location of cell to be selected area.The following examples will illustrate the embodiment of location updating method by taking such a situation as an example.

Location updating method embodiment two：

Figure 15 is the particular flow sheet of Position Updating embodiment of the method two of the present invention.As shown in figure 15, this method includes：

Step 1501, the heart in a call, at least provided with the position area of two mutual bound edges.

In this step, the location area information configuration of cell can be carried out using foregoing respective position area configuration mode.

Step 1502, cell by the location of area identification information broadcast itself to terminal.

In this step, the mode and cell broadcasting position area identification information that the base station where cell obtains this cell position area identification information can be identical with embodiment one to the mode of terminal, just repeat no more here.

Step 1503, when terminal carries out cell reselection, judge whether the cell to be selected of terminal is in present position-region, if so, then performing step 1504, otherwise perform step 1505.

Step 1504, without location updating and this flow is terminated.

Step 1505, target location area is determined from the common location area of cell to be selected and current persistent district, carries out location updating.

In step 1505, when the position area that cell to be selected and current persistent district are co-located on is one, directly the position area can be regard as target location area.When the position area that cell to be selected and current persistent district are co-located on is more than one, the position area in the more than one position area that cell to be selected and current persistent district be co-located on is selected as target location area, for example, random from the position area that these are co-located on or arbitrarily selection one is as target location area.

In step 1505, when the position area that cell to be selected is co-located on current persistent district is not present When, the position area in one or more position areas residing for cell to be selected can be selected as target location area.For example arbitrarily or random selection one position area be used as target location area.

In the present embodiment, after location updating success, it may further include terminal and preserved the cell to be selected as persistent district, and using target location area identification information as present position-region identification information.For example, location updating success message is sent to terminal by call center, terminal knows whether location updating succeeds by the message.

Method flow in the present embodiment is with the difference in embodiment one, when determining target location area, directly selects the position area in one or more position areas that cell to be selected is co-located on current area as target location area.The operation of other steps is identical with embodiment one, and the method flow in the present embodiment can equally be implemented in the system shown in Figure 14.

In the embodiment of the present invention, it is determined that during the area of target location, if there is multiple optional position areas, i.e. cell to be selected, can arbitrarily or the one of position area of random selection is used as target location area simultaneously in multiple position areas；Target location area can also be used as according to certain policy selection one position area.The following examples are to introduce location updating method in such cases.

Location updating method embodiment three：

In the present embodiment, it is determined that during the area of target location, determining target location area according to certain strategy, being specially：Selected further combined with terminal current location relative to the position in each optional position area.

The flow of the present embodiment Position Updating is identical with embodiment two, simply in step 1505, the position area that is co-located on when cell to be selected and current persistent district for it is more than one when, relative to the position relationship in each optional position area determine target location area according to terminal is current.

In the present embodiment, using the distance standard alternatively of terminal current location to each optional position district center, selection position district center that position area nearest apart from terminal is used as target location area.The specific mode for determining target location area has two kinds：

First, the geographical location information of cell broadcasting position district center, terminal determines target location area.A, may further include the geographical location information of the position district center pre-saved in step 1502, in cell broadcast signals, and terminal obtains the geographical location information of position district center by receiving broadcast message.

B, in step 1505, terminal can be using GPS location method or the base station of mobile network Localization method obtains the geographical location information of oneself, and terminal obtains the distance for oneself putting district center in place by comparing the geographical location information of oneself and the geographical location information of the position district center obtained.

C, in step 1505, the position area that the distance of selection terminal to position district center is minimum is used as target location area, progress location updating.

2nd, the geographical location information of Cell Broadcast CB center of housing estate, terminal determines target location area.

A, in step 1502, terminal can also obtain the geographical location information of oneself according to the geographical location information of center of housing estate to be selected, for example, directly it regard the geographical location information of center of housing estate to be selected as the geographical location information of oneself, the geographical location information of the center of housing estate pre-saved is may further include in cell broadcast signals, terminal obtains the geographical location information of center of housing estate by receiving broadcast message, and as the geographical location information of oneself.According to " one, method, terminal can obtain the position relationship at the center in oneself multiple position area residing for cell to be selected.

Among actual, the geographical location information of center of housing estate can be the center deviation degree information of a center deviation degree information, i.e. center of housing estate and position district center, for example, can amount to 16 values to represent this center deviation degree with 0 ~ 15：0 represents that center of housing estate distance and position district center is less than or equal to 100 meters, 1 represents that center of housing estate distance and position district center is more than 100 meters, less than or equal to 300 meters, 2 represent that center of housing estate distance and position district center is more than 300 meters, less than or equal to 500 meters, 3 represent that center of housing estate distance and position district center is more than 500 meters, less than or equal to 700 meters etc..

B, in step 1505, terminal can compare center deviation angle value of the cell to be selected in each position area at their own, and select the less position area of center deviation degree as target location area progress location updating.

Determined using above two mode behind the area of target location, ensure that terminal after location updating, as much as possible bring himself into the nearer place of distance and position district center, i.e., terminal is in position district center area as far as possible.

Equally, in cell broadcast messages, center of housing estate can also be included to the minimum range reference value on the border in each position area, this reference value can be an actual distance value, can also be a border irrelevance information, for example, can amount to 16 values to represent this border irrelevance with 0 ~ 15：0 represents the minimum range on center of housing estate distance and position area border for less than or equal to 100 meters, 1 represents the minimum range on center of housing estate distance and position area border for more than 100 meters, less than or equal to 300 meters, 2 represent the minimum range on center of housing estate distance and position area border for more than 300 meters, less than or equal to 500 meters, 3 The minimum range for representing center of housing estate distance and position area border is more than 500 meters, less than or equal to 700 meters etc..So, it is determined that during the area of target location, in the minimum value that center of housing estate distance and position area border can be selected, the position area corresponding to that maximum minimum value is as target location area, or selects the position area corresponding to the irrelevance maximum of border to be used as target location area.That is, that farthest position area of selection position area frontier distance center of housing estate so, can make the terminal after location updating try one's best and be in the heartland in position area as target location area.Here, the distance of position area border and center of housing estate is minimum value of the center of housing estate to position area border.

Certainly, can also be with the minimum range on cell boarder and position area border as border irrelevance, equally, it is determined that during the area of target location, the maximum position area of this border irrelevance can be regard as target location area among actual.Cell boarder has with position area border when intersecting or be overlapping, and it is 0 that this, which deviates angle value,.Here, when cell boarder is when outside position area border, this deviation angle value can also be arranged and be also 0 or be a negative value, be, for example, -1.

The method flow of the present embodiment can equally be implemented in the system shown in Figure 14.

The selection in position area is carried out using above-mentioned strategy, be ensure that after cell reselection is carried out, terminal is in the central area in some position area, so as to greatly reduce the possibility of frequent location updating of the terminal caused by moving back and forth.

Among actual, in order to reduce the consumption that target location area is determined when terminal carries out location updating, it can directly inform terminal it is determined that during the area of target location in cell broadcast messages, the position area scope that should be selected, this can be by multiple Location Area Identification of Cell Broadcast CB, directly certain several or some Location Area Identification is specified to be identified as position candidate area, to reduce the scope in terminal selection target position area.For example, directly using the corresponding position area of some Location Area Identification as position candidate area, so, terminal is when it is determined that target location area is identified, directly using the position candidate area as target location area, consumption of the terminal caused by determining target location area can be so reduced.Here for ease of description, using the position candidate area in the location of cell area as master site area, those non-candidate position areas in the location of cell area are regard as secondary position area.When the location of cell area identification information is preserved in community configured information, it is master site area that can increase a major-minor mark to distinguish which position area in the location of cell area, and which position area is secondary position area.Reference picture 4, there is as shown in table 6 below, when major-minor mark " oneself represents master site area that the corresponding position area of the Location Area Identification is the cell when being 0 to ^, when major-minor mark " ^ oneself secondary position that the corresponding position area of the Location Area Identification is the cell is represented when being 1 Put area

Table 6

From table 6 as can be seen that when for a cell configuration master site area, those can be typically selected so that the cell is used as the master site area of the cell closer to the position area of its central area.Certainly, among actual, the master site area of a cell can also be configured according to other factorses.

Among actual, master site area identification information and secondary position region identification information can also be respectively stored in different memory blocks.For example, in the case where master site area mark quantity is certain, master site area identification information being placed on before a list, secondary position region identification information is placed on behind the list.Reference picture 4, there is as shown in table 7 below, it is assumed that in each position area residing for a cell, only one of which position area is the master site area of the cell, so, the master site area of the cell is identified before being placed on, secondary Location Area Identification is placed on behind the master site area of cell mark.

Table 7

When Cell Broadcast CB master site area is identified with secondary Location Area Identification, master site area mark and secondary Location Area Identification are made a distinction.For example, identifying the storage side with secondary Location Area Identification according to above-mentioned master site area Formula, it is that master site area or secondary position area, so, terminal can distinguish master site area mark and secondary Location Area Identification according to major-minor mark respectively that each corresponding position area of each Location Area Identification of broadcast is distinguished using a major-minor mark.Or major-minor position area is distinguished with different data blocks, for example, being that master site area mark is placed on before secondary Location Area Identification including major-minor Location Area Identification simultaneously in being broadcast the message at one, so, it is master site area that terminal, which gives tacit consent to the corresponding position area of first Location Area Identification,.

When Cell Broadcast CB master site area is identified with secondary Location Area Identification, master site area is identified and the differentiation of secondary Location Area Identification progress can also use different message to broadcast master site area mark and secondary Location Area Identification respectively, terminal distinguishes master site area mark and secondary Location Area Identification according to different message code values.

Terminal, when judging whether a cell belongs to a position area, can first obtain the master site area mark and/or secondary Location Area Identification residing for this cell；Whether the position area is judged in the corresponding position area of master site area mark or whether in the position area corresponding to secondary Location Area Identification, if it is, the cell is in the position area, otherwise, the cell is not at the position area；Or, judge whether the Location Area Identification in the position area is included in master site area mark or secondary Location Area Identification, if it is, the cell is in the position area, otherwise, the cell is not at the position area.

Terminal is when cell to be selected is not in present position-region, and terminal is it needs to be determined that target location area.When terminal determines target location area, it can be that master site area identification information is first parsed from the broadcast singal of cell to be selected, target location area is then determined according to master site area identification information.When master site area identifies only one of which, it is possible to directly regard the master site area as target location area.That is, when terminal re-selecting cell, if it is determined that a cell is cell to be selected, also, mark corresponding position area in the master site area directly can be defined as target location area by the master site area mark only one of which of the cell, then, terminal.And when terminal is not determined cell to be selected also as the cell for wanting gravity treatment, terminal may determine that whether the master site area of the cell to be selected covers the current area of terminal, i.e., whether the master site area mark of to be selected cell is included in secondary Location Area Identification residing for the current area of terminal, if, it is Target cell that the cell to be selected, which can then be selected, using the master site area of the cell to be selected as target location area, carries out cell reselection and location updating.If not including the master site area mark of cell to be selected in the secondary Location Area Identification residing for the current area of terminal, so, the cell to be selected first directly can not be defined as Target cell and carry out cell reselection by terminal, whether terminal can determine whether the signal quality of cell to be selected substantially due to the signal quality of current area, and this can pass through a signal Mass parameter difference is determined, if cell signal quality to be selected is substantially better than current area, then, terminal, which can contemplate, carries out cell reselection as Target cell using the cell to be selected and carries out location updating using the master site area of the cell to be selected as target location area.Certainly, when determining whether cell to be selected carrying out cell reselection as Target cell, can also with further reference to cell to be selected traffic load, the traffic load parameter value can be broadcast out by cell broadcast messages, and terminal obtains the traffic load situation of cell to be selected by parsing the message.

Present position-region identification information can be preserved in terminal, during terminal re-selecting cell, when judging that cell to be selected is not at present position-region, target location area is determined from the master site area residing for cell to be selected, location updating is carried out.Base station belonging to the cell to be selected preserves the identification information in the master site area residing for the cell to be selected and the identification information in secondary position area in the configuration information of the cell to be selected, and the identification information broadcast of the identification information in the master site area residing for the cell to be selected and secondary position area is gone out in the base station；Terminal can receive master site area identification information and secondary position region identification information.

Terminal judges that present position-region identifies whether to be included in master site area identification information and secondary position region identification information, if, then judge that the cell to be selected is in the present position-region, otherwise, judge that the cell to be selected is not at the present position-region.

Terminal from the master site area residing for cell to be selected before determining target location area and carrying out location updating, it can also judge whether current area is in the master site area, if, then perform and the master site area is defined as target location area and the operation of location updating is carried out, otherwise, determined whether to carry out cell reselection according to the cell to be selected according to cell signal quality to be selected or cell traffic load amount to be selected and carry out the operation of location updating.

Terminal can carry out location updating when reselecting cell, target location area identification information is sent to call center, the target location area identification information that call center's receiving terminal is sent, the position area specified by target location area identification information is set to by the present position-region of the terminal.After terminal is updated successfully in position area, target location area identification information is saved as into present position-region identification information.

In community configured information, master site area is identified and secondary position region identification information can in the base station that networking period is configured to belonging to the cell, can also be configured in the base station controller of the base station or its corresponding paging center according to cell identity information.On base station after electricity, master site area identification information residing for respective cell and secondary position region identification information can be obtained from corresponding base station controller or its corresponding paging center, for example, according to the identification information or base station identification information of cell from right The base station controller answered or its corresponding paging center obtain the master site area identification information and secondary position region identification information residing for respective cell.

In major and minor position area mechanism, master site area quickly determines target location area for terminal, also, in most cases, when being a cell configuration master site area, only configures a master site area.The location updating under the quick situation of movement of terminal is so adapted to, location updating success rate is improved.

, with postponing, there may be such situation by above-mentioned various position areas：Some position area covers the cell under the control of two or more calling center apparatus.At this moment, if carrying out paging terminal using traditional paging way, the cell portion being likely to occur in the position area coverage does not have the situation of call terminal.Accordingly, it would be desirable to change paging policy, so that all cells under position area covering initiate paging to terminal.

Figure 16 is the flow chart of the paging method embodiment for above-mentioned situation.It is assumed that in the present embodiment, position area L covers the cell under two calling center apparatus control, is calling center apparatus A and calling center apparatus B respectively.As shown in figure 16, this method includes：

In this step, the calling center apparatus that the cell of position area L coverings is related is calling center apparatus A and calling center apparatus 8.Usually, in a calling center apparatus, the mapping table of the cell under only configuration relevant position area mark is controlled with the calling center apparatus.That is, in the Location Area Identification of A equipment and the mapping table of cell ID, the cell ID under B device control need not be typically configured, in the Location Area Identification of B device and the mapping table of cell ID, it is not required that the cell ID under configuration A equipment controls.In the present embodiment, the cell under more than one calling center apparatus control is covered due to same position area, therefore further configures the related calling center apparatus corresponding relation interval with position in heart equipment in a call.Wherein, calling center apparatus can be represented using the device address, therefore, Location Area Identification and calling center apparatus mapping table are Location Area Identification and calling center apparatus address mapping table in the present embodiment, and calling center apparatus address can be the Destination Point Code or IP address of the calling center apparatus.When identifying the corresponding relation with calling center apparatus address in allocation position area, itself calling center apparatus address can not be configured, and only configures the address of other calling center apparatus of position area association.For example, calling center apparatus A In, allocation position area L and calling center apparatus B address corresponding relation, the address corresponding relation without being reconfigured at position area L and calling center apparatus A；Equally, in a call in heart B, an allocation position area L and calling center apparatus A address corresponding relation.User's mark can be the IMSI or TMSI of mobile subscriber in gsm system for gsm system.

It is assumed that certain moment, calling center apparatus A wants calling user, then following operate is performed：Step 1602, calling center apparatus A is identified according to user, user's mark and Location Area Identification mapping table that lookup is preserved in itself, obtains corresponding Location Area Identification.

Step 1603, calling center apparatus A carries out paging from the corresponding cell information of mapping table acquisition of the Location Area Identification configured with cell ID itself, and according to user identity information and the cell information obtained according to the Location Area Identification obtained in step 1602 to these cells.

Step 1604, calling center apparatus A is according to the Location Area Identification obtained in step 1602, obtain other calling center apparatus addresses associated by the Location Area Identification from Location Area Identification and calling center apparatus address mapping table, namely calling center apparatus B address.

Step 1605, judge whether to get calling center apparatus B address, if do not got, terminate this flow, otherwise, perform step 1606-1607.

Step 1606, according to the calling center apparatus B of acquisition address, paging is carried out to calling center apparatus B.

In this step, location area information and user identity information are included in paging information.

Step 1607, calling center apparatus B is according to the position region identification information of reception, paging is carried out to these cells from mapping table acquisition corresponding cell information of the station location marker configured with cell ID itself, and according to user identity information and the cell information obtained.

In the present embodiment, step 1603 and 1604 is that order is performed successively, in fact, step 1603 and 1604 can be performed with random order or performed simultaneously.

In the present embodiment, Location Area Identification and calling center apparatus address mapping table can be directly configured in user's mark and Location Area Identification mapping table, or, it is each independent with user's mark and Location Area Identification mapping table.When being directly configured to user's mark and during Location Area Identification mapping table, the mode used can be for：Increase a domain in user's mark and Location Area Identification mapping table, the related calling center apparatus address in the position area is recorded in this domain, so, while Location Area Identification is obtained according to user's mark, you can obtain correspondence position area mark associated Calling center apparatus address.

Using above-mentioned paging method, when position area covers the cell of multiple calling center apparatus controls, it is possible to realize that all d under the position area coverage, area carry out the purpose of subscriber paging.

Position area provided in an embodiment of the present invention collocation method, the method in cell broadcasting position area, paging method, location updating method and system can be seen that more than, The embodiment provides one kind at re-selecting cell, the total solution of the frequent location updating problem occurred, allow users to according to actual needs, resident cell is most suitable in selection, so as to ensure the access performance of terminal, and in densely populated city, in the case that radius of society is small, it is possible to reduce the updating of terminal position number of times in position area intersection.

Presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
