Description

The particular procedure of repeated paging

The present invention relates generally to be used to improve the telecommunication system and the method for paging, relate to telecommunication system and the method for using the paging historical characteristics improvement paging relevant especially with each mobile subscriber in the telecommunication system.

From the demonstration of the radio ability of Guglielmo Marconi in 1897 provide and navigate by water the boats and ships in the English Channel continuous get in touch since, radio communication has obtained noticeable progress in century in the past.Since the discovery of Marconi, new wired and wireless communications method, and professional and standard is adopted by people everywhere in the world.This progress is quickened, and especially at last decade, mobile radio industry is increased with the order of magnitude by the progress of many science and technology, makes portable radio device less, and is relatively more cheap and more reliable.The phone that moves in 10 years of future will and finally be caught up with existing cable network and continue to occur exponential increase because of the wireless network reciprocation.

In each radio telecommunications system inside, be useful on paging or contact in this intrasystem mobile radio station paging channel of the automobile cellular telephone of listening paging signal for example.Along with the increase of using honeycomb and other radio communication, the new mobile subscriber in the operation and the quantity of cellular telephone increase apace.Owing in given wireless or cellular telecommunication system seldom available paging channel is arranged usually, this is fully aware of: preserve this limited system resource for keeping suitable paging capability and preventing that communication delay from being important.

A kind of time-delay occurs in mobile subscriber in the given telecommunication system when having roamed outer their local overlay area.Certainly, that positioned area of paging will be failed, so the scope of this system extension paging is so that comprise the zone of the vicinity that can arrive this mobile subscriber.Yet, long delay may appear, because the paging of the widening range of the execution that continues, and the caller may think that this calling has been lost and stop this calling prematurely.Therefore such paging not only consumes valuable system resource but also may cause the client dissatisfied.

Therefore an object of the present invention is to change wireless system so that improve or overcome above-mentioned paging problem and reduce the client and be unsatisfied with.

Other purpose of the present invention is to reduce the essential paging quantity of contact mobile subscriber in wireless system.

Another purpose of the present invention is the quantity that adapts to user's the minimizing of characteristic separately paging by the paging protocol of adjusting telecommunication system neatly.

Further purpose of the present invention is by following the tracks of each paging historical characteristics relevant with the specific mobile subscriber in this system and adjusting the quantity that paging protocol reduces mobile subscriber's paging according to these characteristics.

The present invention is directed to and be used for controlling the mobile subscriber's of radio telecommunications system the paging quantity and the system and method for scope.Relevant each user's paging information is stored in the switching center/visitor location register inside of that user's corresponding mobile and changes paging to this user according to this paging information.

From the accompanying drawing of general introduction, the following detailed description and the appended claims of presently preferred embodiment of the present invention can obtain more complete understanding of the present invention and scope thereof briefly below.

Fig. 1 is the schematic diagram of the beehive network system of routine;

Fig. 2 is the schematic diagram that further specifies cellular network shown in Figure 1;

Fig. 3 is the schematic diagram that further specifies the part of cellular network shown in Figure 2; With

Fig. 4 is the block diagram according to mobile switching center/visitor location register of the present invention.

Referring to accompanying drawing the present invention is described more completely hereinafter now, expression preferred embodiment of the present invention among the figure.Yet this invention may realize and should not be interpreted as being restricted to the embodiment that proposes here with many different formation; On the contrary, provide these embodiment,, and fully pass on scope of the present invention for those skilled in the art so that this discovery is comprehensive and complete.

Referring to Fig. 1, a public land mobile network (PLMN) is shown, such as cellular network 10, it comprises a plurality of regional 12 again, each zone has 14 and integrated visitor location registers of a mobile switching centre (MSC) (VLR) 16.MSC/VLR zone 12 comprises a plurality of bands of position (LA) 18 again, this band of position (LA) 18 is defined as the part in given MSC/VLR zone 12, wherein mobile radio station (MS) 20 may freely move, and upgrades the MSC/VLR zone 12 of positional information to that LA 18 of control and needn't send.Each band of position 18 is divided into many mesh 22.Mobile radio station 20 is actual equipment, for example is to be used for automobile telephone machine or other portable telephone of communicating by letter with cellular network 10 by the mobile subscriber.Base station (BS) the 24th, actual equipment, for simple table is shown a radio tower, the radio that it is provided to the geographic area of mesh 22 covers, and handles therein and from the radio traffic of MS 20.

Further with reference to figure 1, PLMN service area or cellular network 10 comprise an attaching position register (HLR) 26, it is one and keeps all user profile, the database of international mobile subscriber status (IMSI) number and other information of managing, user file for example, a database of current location and routing information.HLR 26 can place or professional one or more MSC14 that separates with given MSC14 is common, and the latter is illustrated among Fig. 1.IMSI is the unique 15 figure place identification numbers that are assigned to each mobile radio station 20, and the mobile country code (MCC) that comprises three numerals, the Mobile Network Code (MNC) of two (perhaps three) numeral, with a mobile user identification number (MSIN), two mobile subscriber's status (NMSI) numbers that constitute a country in back.

VLR 16 comprises the relevant information that is currently located at all mobile radio stations 20 in the MSC/VLR zone 12.If mobile radio station 20 is roamed into a new MSC/VLR zone 12, the VLR 16 that is connected to that MSC14 is with the data (notifying the HLR current location of 26 relevant these mobile radio stations 20 simultaneously) from the relevant mobile radio station 20 of HLR database 26 requests.Therefore, if the user of mobile radio station 20 will make a phone call, this this locality VLR 16 will have the identification information that needs and needn't inquire this HLR 26 again.

Referring to Fig. 2, the another one view of expression PLMN service area 10 illustrates the MSC14 that is used for one of above-mentioned MSC/VLR zone 12 and integrated VLR 16, wherein comprises band of position 18a-18f respectively.As discussed, specific MS 20 may not transmit more new data in specific LA 18 inner roamings.Therefore, for example last among the LA 18a to use the mobile subscriber of their MS 20 will be at first paged at specific LA 18.As having understood and further discussed in the present technique field about Fig. 3, can be at the mobile network of the described specific MS 20 that seeks described mobile subscriber at whole LA 18a, promptly in all mesh 22 or its subclass paging they.By this way, its MS 20 preferably can easily communicate by letter and responds page communication the mobile subscriber of active state.

With reference now to Fig. 3,, as described and about shown in Figure 1, each band of position 18 in specific MSC14/VLR 16 coverages is subdivided into a plurality of mesh 22, is expressed as mesh 22a-f in Fig. 3.Certainly should understand that each mesh 22 in corresponding LA 18 is that the identical MSC 14/VLR 16 by corresponding LA 18 serves.Will also be appreciated that the service mobile network can use the specific radio coverage of the given mesh 22 of mesh whole world status (CGI) identification.Different mesh 22 in given LA 18 can use mesh identification and distribute to base station identity code (BSIC) difference of each serving BS, just as known in the art the road.

Conventional paging technique is the mobile subscriber the above-mentioned cellular network 10 of local paging at first, continue the paging of wide territory up to mobile subscriber's response or make connect the distribution time that expires till.Again with reference to figure 3, initial " this locality " paging is normally in inside, a band of position, for example as the outstanding LA 18f inside shown in this figure.Yet, should understand that initial paging can be narrower and be replaced is inside at one of specific mesh 22a-22f.If not to the local page response in the LA 18f, then being LA 18a-f in all bands of position 18 by MSC 14/VLR 16 services, this mobile subscriber carries out " whole world " paging.

Conventional paging protocol is typically followed the process in the whole world then of this this locality steadily, regardless of requirement and no matter the user's who moves the action formerly to system resource.For example, to the situation that failure is attempted in given mobile subscriber's nearest paging, i.e. not response of user in this locality even paging zone in the whole world, in the near future other local paging can not success.Like this, skip this user's local paging step and replace that to advance at first global that user of paging will be more effective using system resource.This caller also will be benefited because with this telex network or the indication that takes defeat in they will be subjected to less delay.For caller's additional benefit, the other time can be distributed to global paging in this example.

Therefore, the modification to the MSC 14/VLR 16 that serves given mobile subscriber realizes these and other advantage of the present invention.More particularly, the paging protocol of Ti Chuing hereinafter replaces following the strict program of conventional system, but resilient and can be adapted to given mobile subscriber around situation, just as described in more detail below.

What be shown in Fig. 4 is the representation of the VLR 16 shown in front the figure, comprising a plurality of user's operating datas record 16A of the corresponding a plurality of mobile subscribers that get in touch with the MSC 14/VLR 16 that is discussed.Corresponding user data record 16A comprises the information of relevant this corresponding mobile user's paging history, the i.e. information of the specific situation of relevant user's paging.

Be stored in paging historical information among the corresponding data record 16A and comprise some or all following illustrative examples:

1. the time (TIME) that last paging is attempted

Specific recently or final time at interval in the sum (TOTAL) of paging trial

3. the success (SUCC) of last paging

4. the response time of successful paging (TIME RESP)

Described specific recently or final time at interval in the quantity (NUM UNSUCC) of failure paging trial of last paging

6. the mesh sign (identification number) that the mobile subscriber who knows at last contacts with network.

All or operating data above some can be stored in the corresponding field in this data record 16A.Preferably, each the data record 16A in the VLR 16 has an identifier, and for example a pointer is discerned this specific mobile subscriber uniquely.Such identifier preferably comprises unique international mobile station sign (IMSI) number of this user at least, and is as directed.Certainly should understand that the identification schemes that substitutes may be useful under this situation.Will also be appreciated that time variable TIME and TIME RESP indication standard time reference, SUCC is a Boolean sign, and TOTAL, and NUM_UNSUCC and ID be integer preferably.All above-mentioned field variablees and any other or replace the field variable and can be stored in the respective field of corresponding data record 16A in the mode of routine.

What also store in VLR 16 is to be used for the exploration or the rule database 16B that judge based on the information that stores in above-mentioned data record 16A.Should understand any or two (both sides) operating datas record 16A and heuristic data storehouse 16B can be stored among the MSC 14 or among the MSC 14/VLR 16 of combination.Will also be appreciated that the heuristic data storehouse 16B that for example is stored among the VLR 16 can be changed by the Systems Operator, makes this intrasystem paging performance of better optimize.

Describe hereinafter and be stored in an interior specific exploration of heuristic data storehouse 16B used according to the invention or an example of algorithm.

If paging history=(H1)

Time≤1 minute;

Sum 〉=3;

(the previous paging of failure) of SUCC=mistake;

TIME RESP=0 (inapplicable)

NUM?UNSUCC≥3；

ID=(mesh identifier);

Then

First paging: the whole world, paging is overtime=and 8 seconds;

Second paging: do not have second paging.

The mobile subscriber who satisfies the superincumbent illustrative or paging standard soundd out probably outside scope because had in the time cycle in the end three or more trial pagings they and do not have response.Therefore, local paging is unnecessary and does not carry out.Replace, this system carries out the paging in the whole world immediately.As discussed, this has preserved the paging resource, also reduces the time before indication is sent to the calling subscriber, and it preserves Internet resources again, because the calling party connects their calling quickly.

Being described below the another one that is stored in the 16B of heuristic data storehouse explores:

If paging history=(H2)

Time≤5 minute;

Sum=1;

SUCC=real (the last paging of success);

TIME RESP=1 second;

NUM?UNSUCC＝0；

ID=(mesh identifier)

Then

First paging: paging mesh ID and mesh on every side;

Second paging: the whole world.

Here the mobile subscriber has just replied and replied a paging in last 5 minute.Like this, this user may remain in this specific mesh, the mesh 22e in Fig. 3 for example, perhaps one of mesh tightly around, mesh 22a for example, 22b, 22c, 22d (with the mesh of the mesh 22e of adjacency in contiguous LA 18, not shown).Therefore, the specific mesh of discussing by target at first can be optimized the paging resource.If failure, the then best global paging of user.

In the above described manner, can realize the twin target of saved system resource and customer satisfaction.

Should understand that in addition data record 16A can comprise the priority of this paging, example is priority field as shown in Figure 4.For example, mobile subscriber (perhaps caller) can pay the higher price of automatic global paging, therefore replaces above-mentioned agreement.Similarly, the user can indicate a low priority, for example, if corresponding M S 20 only is used in the narrow zone.Will also be appreciated that above-mentioned parameter is the time, sum, SUCC or the like are preferably in registration or the time initialization that connects of IMSI.

Will also be appreciated that preferably dynamic database of heuristic data storehouse 16B, except changing, can itself change, add up sign indicating number type in a plurality of user's data and the response data so that the better service customer data base as it by the Systems Operator.For example, explore among H1 and the H2 above-described any or two, the change limitation of time and sum for example can respond user's use and system to be needed the artificially or automatically changes.

The description of front is to realize preferred embodiment of the present invention, and scope of the present invention should not limited by this description.
