Abstract
The present invention relates to determine when can think that thereby a certain mobile phone is in off-position can be avoided the relevant mobile phone of paging when terminating call a kind of method in the mobile telephone network, the time that record is each and mobile phone carries out wireless link, when terminating call, calculate this end call time and writing time difference between the two.When this time difference surpasses certain to specified time, indicate that this mobile phone is in off-position.
Description
Relate generally to of the present invention is based on the cellular mobile phone radio system of GMS standard (Global System for Mobile Com-munication), specifically, relate to a kind of method system, be used for judging that when being used for mobile phone at a mobile telephone network can be considered to outage, thereby when terminating call, avoid this mobile phone of unnecessarily paging.
The GMS network comprises substantially: at least one BSS of base station system, this base station system comprise a base station controller BSC and base station transceiver BTS.The GMS network also comprises a mobile telephone service switching center, an original location register and a customer location register VLR.
Each mobile telephone station MS belongs to the HLR of a primitive network, and permanent customer data is stored in wherein.When a mobile telephone station was deposited among the MSC/VLR as a new user, the HLR of this mobile telephone station just sent the duplicate of relevant user data to MSC/VLR.
At present, the capacity of the radio path of mobile telephone system is limited, so people have adopted various side to attempt to maximally utilise existing radio resource.
For utilizing existing radio resource better, send and when mobile phone sends signal to mobile phone, the signal between need making from the network to the mobile phone sends and sends from mobile phone to internetwork signal reaches uniform distribution.
When a certain mobile subscriber is received in certain calling, as far as possible little for the zone that makes called party place that will paging, normally radio net is divided into some position districts that (Cell) form by one or more " unit ".The result who does has so mainly reduced the load of radio-ray path on from network to the mobile phone direction.Therefore, when paging, have only on the radio net in the confidential some areas that are determined of paged mobile phone load is arranged.A program of fulfiling by network when this is a certain called mobile phone of paging.Therefore produce some such programs, in these programs, each mobile phone needs the situation of movement of informing network from position district to the another one district, and urges these mobile phones to carry out these programs.These programs are at the GSM(group selection network) be called location update procedure in the system.
Light knows which district certain known mobile phone is in is not enough, because this mobile phone may cut off its collection of letters power supply thereby not look for it by paging.Therefore total hope is avoided it is carried out paging when knowing that its power supply of a certain mobile phone is not connected.So just can under the situation of signaling to mobile motor, avoid unnecessarily increasing load to radio net from network.
For when the power supply of determining a certain mobile phone in the network does not connect, always be in gsm system, to add one to be called the program that IMSI separates.The IMSI separable programming is the mobile phone informing network, and power supply is with cut program.At this moment, network just deposits this information in relevant cellular radio, i.e. MSC/VLR(mobile services switching centre/external Customer Location register of relevant user among the GSM).When call terminations, just do not proceed paging, thereby saved radio capability thereafter.
Yet the IMSI partition method has some weakness.At first, mobile phone informing network power supply just be cut off (promptly fulfiling the IMSI separable programming) information may not reach network etc. former thereby lost efficacy because of information.In addition, this mobile phone may be in the radio shielding district, makes mobile phone not send information to network.These weakness mean that the attempt meeting of later paging is failed all the time, and may make radio net be in the unnecessary state of accepting load.
Therefore, the extremely important function of each MSC/VLR is so-called business activity monitor program or interior latent separable programming.Interior latent separable programming is that although promptly network is not received the information that any IMSI separates from mobile phone, mobile phone may be in off-position fully with such basis that is assumed to be.
In latent separable programming hypothesis, last and specific mobile phone carries out wireless link a period of time afterwards, mobile phone is connected with the mains never again.Yet, also to be in "on" position at informing network self after certain given interval even this method requires mobile phone also not move to new position district again.The GSM regulation and stipulation will regularly be reported the position of mobile phone.
Correctly work for latent separation in making, report that regularly the time of mobile phone position must be shorter than interior latent disengaging time, promptly be shorter than and think that mobile phone has cut off the power supply that a period of time before.
In the system in early days, interior latent separable programming is by distributing continuous time supervision or monitoring program to carry out for each user among the relevant MSC/VLR, and this program is just restarted when each and mobile phone carry out wireless link.This time monitoring cycle to when point, just think that mobile phone is in off-position, thereby when terminating should to after just do not carry out paging during calling of generation.Should in duration of latent separable programming set up by MSC operating personnel, and can between 15 minutes and several hrs, regulate.
Above-mentioned solution makes the basic load in the system very big.This is because each special-purpose time monitor program is all occupied the processor ability, and each user of MSC system has the time monitor program (user that those have cut off the power supply or because of time of supervision make an exception to the user that point is considered to cut off the power supply) of continued operation.The user that the MSC/VLR system once stores at one time surpasses 100,000 families.
European patent EP 102,129 has been introduced a kind of radio communications system, and the mobile phone telephone receiver in the system can be communicated by letter with a sender at least.Each sender is posted a letter on some channels, and telephone receiver comprises the tuner of an energy scanning channel.Each sender regularly sends signal on its signaling channel.Telephone receiver has a timer, this timer just starts scanner when not receiving this class signal on the channel that telephone receiver is got in the scheduled time of the duration that is not shorter than described channel signal, scanner is failed when receiving this signal on telephone receiver is won the confidence in addition.
United States Patent (USP) GB 2,244,409 introduces a kind of mobile radio system of threading, and each mobile phone in this system is regularly started shooting, and the purpose of doing like this is to upgrade the capacity of base station mobile phone.This system can store the relevant issues of the mobile phone of nearest registration, comprises nearest time registered and the blanking time of successively registering.This system can determine how could rightly the information that sends to mobile phone be sent out on this basis.Therefore also just can by means of the time interocclusal record determine when can get in touch with mobile phone.
The purpose of this invention is to provide a kind of method and system of eliminating above-mentioned shortcoming, during work, can judge that a period of time after the recent wireless link is long to can be to think that this mobile phone has been in off-position.
According to method of the present invention, the step that achieves the above object is as follows:
Deposit each time mark T1 that links with a mobile phone radio;
When the terminating call signal to a mobile telephone station occurs, deposit the time T 2 of appearance;
Calculate under the described time mark and during described time of occurrence T2 T3;
If described time difference T3 surpasses a scheduled time length T 4, just indicate that called mobile telephone station is de-energized (quitting work).
Be included in the system of the present invention (GSM comprises Mobile Telephone Switching Center) in the gsm mobile telephone network: in described Mobile Telephone Switching Center, comprise:
Deposit the device of time mark T1, the moment that T1 is each and a mobile phone radio links ();
