Abstract
A traffic management system reads TT files obtained from Mobile Services Switching Centers, and processes information included in the records of the files, and on the basis of the information produces a hierarchical graphic representation on a map display. The highest level represents the operator's entire service area, and the lowest level a cell. On each level, traffic intensity is displayed with grades of colour, i.e. the more traffic the stronger the colour. The display is updated automatically as the MSC provides the TT data. The system monitors traffic load in the cells. If the traffic load in any one of the cells exceeds a preset level, the system automatically transmits a command to the MSC to change the logic size of the cell or add a TRX unit, if such is available.
Description
The present invention relates to the traffic management system of cellular mobile communications networks, mobile services switching centre produced TT (toll ticket) record after each was called out therein.This record includes the access success or the failure of pass at least and indicates this calling mesh identifier relevant with which mesh.The TT record that produces at specified time interval is incorporated in the TT file and is for further processing.
Below, will narrate the structure of mobile radio communication with the GSM mobile radio communication of the prior art of Fig. 1 as an example.Communicating by letter between the mobile radio station (MS) in a mesh and this network carried out on radio path through base transceiver station.Base transceiver station is received base station controller (BSC), and this base station controller is controlled several base stations usually.The position of MS is known according to the precision of the so-called lane place (LA) that is made of several mesh.Mobile radio station can be roamed in this lane place and not upgrade its position data.Several base station controllers are received a mobile services switching centre (MSC), and it carries out the basic function of exchange of mobile radio communication.Whole mesh under MSC control are called the MSC district; This MSC transmission of all-calls process of starting and stopping therein from this district.In addition, it is received mobile radio communication external network and passes through the mobile radio communication that so-called gateway MSC receives other operators.
Mobile radio communication also comprises the data of different types storehouse.Attaching position register (HLR) is stored user's data regularly, and with his present location independent.The user data that obtains from HLR is stored in visitor's location register (VLR) during user capture VLR district.
Call out and service fee for the operator can collect to the user, the traffic management of this network partly has a mechanism, utilizes this mechanism will store the data of sufficient amount for the business of each charge.The most important thing is that the relevant charge basis of traffic carrying capacity is made of calling.In MSC,, comprise all necessary informations of calculating these calling telephone expenses in case it has finished just to produce so-called toll ticket record for each calling.The content of this record depends on the switching center's technology that adopted and operator's requirement.Gateway MSC and HLR exchange messages according to the MAP/C agreement and the prior art message comprises following data at least in the TT record segment:
(a) at first, identifier, promptly user's IMS number and produce the MSC identifier of this record,
(b) secondly, the type of calling, that is, this calling is mobile radio station originating call or the calling that is stopped by the mobile radio station that MSC transmits (this means that the TT record also comprises the routing iinformation from switching center to this mobile radio station),
(c) if this switching center is a gateway MSC, then this record comprises routing iinformation GMSC-MS,
(d) if MSC is in another network, mobile radio station end call rerouting information GMSC-MSC then,
(e) call state, the information of promptly relevant access success or failure.The data of failed calls only are used to add up purpose, so the manufacturer of switching center always is not included in him in the TT information,
(f) date, the calling zero hour, duration and characteristic.Last indicates whether voice, data, short message etc. are being discussed,
(g) caller rs number (in mobile termination) or callee's number (in moving the calling of just starting),
(h) charge is collected from user's operator by the target operator under roaming condition;
(i) mesh information (mesh ID), the mesh that the indication incoming/outgoing is called out.
Above listed field be example, and the supplier of switching center can add other field according to operator's requirement.In the I/O of MSC equipment, this document sends Fare Collection System to predetermined interval and further handles the TT record as a file storage.Typically, transmit with 5 to 15 minutes interval, so this represents the real time delay of these data at interval.
The purposes of the graphical presentation of Fig. 2 above-mentioned parameter in the TT record.The field of record comprises time, route, mesh ID, call charge pulse and the EOS field that number, date, the calling of user a and b begin and finish.EOS (selection finishes) is the removing sign indicating number that the reason that does not have connection why is called out in definition.Have 1000 different yards more than that using.Sign indicating number 0 calling that means success, rather than 0 sign indicating number not only indication failure calling but also indicate its reason.
Because mobile radio communication expansion and call density change, this network must be revised continuously.The increase of capacity can be by increasing new TRX unit and also changing by increasing new node (MSC and BSC) and new mesh thereby transmission route in this mesh.For carry out these changes and for operate, maintenance and management function, this network produces different types of information from several position; For example BSC from the mesh acquisition of information of its control, therefore obtains the information as the relevant traffic densities of the function of time.The information that obtains from each information source must be collected and handle with centralized system.In this respect, mobile radio communication does not have different with other telecommunications network.
In present mobile radio communication, the defective of traffic management relates to poor real-time representation.Peak information only after segment length's time ability available.Though the information that relevant traffic densities changes is available, this is just after long delay and with non-digital form intuitively.As a result, traffic capacity may be used up in some mesh because in real time or the dynamic assignment of in fact real-time volume of business be impossible.
The objective of the invention is a system, make traffic management easier by visual representation intuitively and the in fact real-time variation that traffic density is provided.This system should be able to receive the MSC of any manufacturer, need not change its inside function.
The system that utilizes claim 1 to propose reaches this purpose.
Management system is implemented, and makes the TT file that obtains from the MSC of mobile radio communication and comprise the TT record be read out and shift the database that incorporates into this business management system.The information that the traffic management software processes obtains from record, the quantity that counting is called out in mesh, and on map display, produce the hierarchy diagrammatic representation.The term here " hierarchy " expression is top to be whole geographic area under operator's control, has several MSC.The layer of next may be that the zone of a MSC and the layer of next may be the lane place.Lowermost layer is represented by a mesh.Every layer with the chrominance representation traffic densities, that is, traffic carrying capacity is big more, and color is strong more.Demonstration is along with the TT data that MSC provides are automatically upgraded.
Management system also comprises and is used for the logic that traffic load monitors.This logic monitors is loaded with the network traffic in the different mesh at different layers.If traffic load surpasses predetermined degree in zone in a mesh or a plurality of mesh, then this software automatically sends an order to the base station controller of being discussed distribution service amount between overladen mesh and adjoining cells.This can distinguish switching criterion and cross the district from overladen mesh in advance switch to a mesh with less traffic load and correspondingly postponed to distinguish and switch to overladen mesh and carry out on the mesh border by changing.Said method can be described as the size that reduces the overload mesh in logic.If there is the unsteady TRX unit of other what is called to use in the base station, it can be connected and be used in this overload mesh, therefore increases the capacity of this mesh.
Result calculated can be stored for adding up purpose.Statistics for example can constitute the average duration that blocks statistics, every channel call, channel usage degree or the like.
At length narrate the present invention below with reference to the accompanying drawings, wherein:
Fig. 1 represents prior art GSM structure of mobile communication network,
Fig. 2 represents the field of TT record,
Fig. 3 represents the connection of traffic management system to mobile radio communication,
Fig. 4 represents to order the possible flow chart of automation; With
Fig. 5 is illustrated in the network traffic load on the map display.
Fig. 3 represents to the whole mobile radio communication on the dotted line A left side.Mobile radio communication can have several MSC, at Fig. 1 a MSC is shown.With all present MSC of accurate interval is that the operator produces a TT file, this document outside the field of Fig. 2, comprise all other fields at least but except the EOS field of relevant possible failure channel request.If switching center still produces such field, but because such or such reason comprises it in the TT record, then this field also will be directed to traffic management of the present invention system dividually.If switching center does not produce such field, the measure that must take to be correlated with in this switching center produces this field.
Traffic management of the present invention system is represented on the right side of interface A.It is provided the TT file that obtains from this MSC: the TT field, beginning of promptly calling out of number A, number B, routing iinformation, metering data and concluding time and pulse at least, mesh ID and utilize the call data EOS that blocks.MSC produces new TT file with predetermined interval, and a typical sequence is 5 to 15 minutes.
The file that is received by the traffic management system is transmitted by this system handles.This system distinguishes these records and handles them.In case when using traffic densities to use, the mesh id field is added to their database.Because the TT record also comprises the mesh identifier of sending calling of each calling, or its termination, represent the quantity of this mesh, calling out from the record sum that the TT file that receives calculates with identical mesh ID.If it is for example per 10 minutes of MSC produces a new TT record, then above-mentioned and be illustrated in the calls in this mesh during in the past 10 minutes.By this way, can promptly set up the calls of each mesh of this network.By the calls addition in the mesh (under the control of identical BSC) of lane place, can easily calculate the traffic densities in this lane place.Correspondingly, can obtain the traffic density of MSC area by the calls in this lane place of addition.Therefore, traffic density can utilize the accuracy computation of mesh, lane place, MSC area and a whole mobile radio communication.
On display unit, represent traffic density with graphic form, make this map show expression operator's whole operation district, for example Finland.Because where the mesh of knowing MSC district, a lane place and having a specific identifiers is positioned at this map, the hierarchy that can easily produce traffic density is represented.Top, traffic density can show in whole network area or with the MSC district.Hit mouse by the MSC district in hope, the resolution that map shows has increased and this display is represented traffic density with the lane place.Hit mouse again one time, map shows the traffic density of representing this lane place with mesh, and last lowermost layer shows the traffic density in the mesh.At every layer, can show the alphanumeric information of relevant this layer.
Traffic density can colourity show: at the mesh layer, call out with for example red expression of pixel.As a result, the calls that carries out in this mesh is high more, and this mesh is red more.Correspondingly at other layer, the red kilsyth basalt of this geographic area shows the traffic density in this zone.Because traffic management software always upgrades this demonstration when receiving new TT file from MSC, so the clear image that provides traffic density to change.
The result that TT file is in front handled after receiving is stored in the memory, and this expression is by showing the result of calculation of requirement continuously, and map shows the variation of most clearly representing traffic density.For example, the map demonstration can represent how specific red sector moves along road according to traffic density.Above-mentioned figured flow chart is represented the direct sequence of difference in functionality: data are read out, and the value that needs is calculated and illustrated on map shows.Irrelevant with the high number of different recording, computational process is piece very.Those skilled in the art will appreciate that the information that obtains from the TT file also can be used for various statistics purposes except computing service density.For example comprise Internal call in the average duration of calling that blocks each channel in statistics, the mesh, channel usage degree, this mobile radio communication to the ratio of all-calls, enter the calling of mobile radio communication and the calling of starting from this mobile radio communication to the ratio of all-calls etc.
It is one of characteristic according to system of the present invention that the graphical map of call business density shows.The characteristic of another sign utilizes the built-in logic of this system to provide traffic load in can monitoring wireless network and the order that utilizes this system to produce automatically to optimize network capacity.If mesh overload, perhaps near the upper limit of capacity, then system automatically sends order to this MSC, for example reduces by the logic size that changes the mesh of being discussed and distinguishes switching criterion and/or use an additional transceiver unit TRX in this mesh, if this is available.
Fig. 4 represent as how simply and rapidly mode realize the present invention.At first, read needed TT data (square frame 1).Block to show and the order automation utilizes indicating call failure and successful EOS field and mesh id field to carry out.At square frame 2, utilize following formula to calculate and block percentage E.
E=(channel request of in specific mesh, failing/all channel request in this mesh) * 100%.
For each mesh, whenever obstruction percentage calculates in this system when MSC receives new TT file.When the obstruction percentage E of mesh surpasses preset value (square frame 3), this system automatically send order to this MSC to regulate the logic size of this mesh, promptly change crossing district's switching criterion (square frame 6) and enlarging adjoining cells of this mesh, promptly change their district's switching criterion (square frame 7) excessively, perhaps in this mesh, increase additional TRX (square frame 5).MSC order BSC controls this mesh and carries out desired process.
This system that handles mass data can use effective procedure code utilization to realize based on PC equipment; Therefore, for example the Unix work station is unwanted, does not resemble the traffic management system in the fixed network of prior art.This system can receive the MSC of any manufacturer.
At last, Fig. 5 presentation graphic map shows representation.The figure shows operator's mobile radio communication top, whole Finland.Black region is represented very high traffic density.
Should understand that top narration and relevant figure thereof just will illustrate the present invention.It will be apparent to those skilled in that: do not depart from the scope of the present invention with mental condition under can change and revise.The present invention has narrated in conjunction with a mobile radio communication, but clearly, in comprising the mobile communication system of several MSC, this equipment can be installed in they one of in, from the information of other switching center with can use suitable the connection to send as network X.25 to the order of this switching center.
