DE10222583A1 - Mobility control method for communications system uses transmitted mobility information relating to actual and/or maximum mobility of communication station - Google Patents

Abstract

The mobility control method has mobility information (MC) relating to the actual and/or the maximum mobility of a first communication station (UE) transmitted via a communication link (V) to at least one second communication station (NB). The mobility information may define the spatial limitation of the mobility of the first station, e.g. the mobility class, the received mobility information used for management of network resources. An independent claim for a mobility control device for a communications system is also included.

Description

The invention relates to a method for Mobility control in a communication system with the generic features of the independent claims.

Radio communication systems according to are generally known Example of the standard GSM (Global System for Mobile Communication) or UMTS (Universal Mobile Telecommunications System). Mobile communicate with these systems subscriber stations, for example mobile phones or Notebook computer with fixed network access stations on the network side via radio interfaces. A major problem with such cellular established mobile radio systems consists in the most possible optimal use of radio resources when operating different stations on the participant side, each with very different characteristics. For example, for communication on the part of various participants Various services are required to stations Example, on the one hand, services that have a high data rate make necessary, and on the other hand services which a require a low data rate. In particular Data flow characteristics and quality requirements can vary widely his. Another problem is that the Participant stations with a view of their given Mobility spatially completely arbitrary and within one only technically limited speed range can move.

From a network perspective, it is therefore not known in advance how many participant stations one Request communication link, which service requirements exist and how the spatial mobility behavior of the stations is. Planning cellular networks is therefore difficult to carry out and to a large extent fraught with uncertainties.

During operation, complex algorithms in the Access networks are used so that the radio resources and Manages network resources as well as possible and can be allocated. On the one hand, the possible exploitation should of the available resources should be as high as possible, on the other hand however, the network must not become overloaded.

To largely independent of the stations on the subscriber side their individual characteristics and needs all from Services provided by the communications network can, the UMTS communication network has both Access area as well as in the core network via all necessary Functionalities. Mobility comes with a large number of functions and mechanisms, for example location management (Location Management), transfer functions (handover) and Power control supports what that Communication network, however, with a view to participant mobility not only flexible but also complicated, expensive and difficult makes it plannable.

The object of the invention is to provide a method or Devices for processing mobility information in to improve a communication system. In particular, should the administration of various stations on the participant side, which have different mobility requirements become.

This task is accomplished through a process for processing a Mobility information in a communication system or by a device for processing a Mobility information in a communication system with the features of independent claims solved. advantageous Refinements are the subject of dependent claims.

A method offers an advantageous solution for processing mobility information in one Communication system in which a connection between at least one subscriber station, for example one Mobile phone or a radio-based notebook, and one network-side access station a mobility information regarding the actual mobility of the participants Station is transmitted. The actual mobility relates thereby on a current mobility or actually possible mobility in the foreseeable future. Under A station on the subscriber side is a radio-based one Station, in particular to understand a data terminal, the term on the subscriber side essentially only for Clarification of the difference to the network side Access station or base station can be seen. Mobility information can be available in many forms, for example as discrete digital data values or as analog values, such as an analog measurable power value of a signal.

According to particularly preferred embodiments, the Mobility information Information about a limitation of the spatial or speed-dependent mobility. there it is possible to actually view the information as currently specify the applicable value, especially for both sides of the Radio interface of fixed stations. It is also possible that Mobility information as the maximum permissible mobility value to be specified, for example with regard to only within a radio cell, a group of radio cells or possibly even only within a certain area of space permitted movement within a radio cell. Corresponding can also set maximum allowable speeds of movement the station can be specified, expediently as possible speeds typical maximum Speeds of a walking, a cycling and one with one Participant driving a motor vehicle as usual limit values are applicable. In this regard, there is also a division into fixed mobility classes appropriate.

In addition to the possibility of only the mobility information as statistically usable information from the subscriber-side station to the network-side access station a fixed limit is also possible. This means, it is also a firm assignment of a single mandatory one Mobility, such as stopping at one Location, or the allocation of a mobility spectrum or the Allocation of an upper mobility limit possible.

Such assignments can be made by a participant who is called user of the subscriber station manually can be entered. Additionally or alternatively, at Commissioning of a certain service automatically depending on the service or by manual selection of the service by the Participants determine a required mobility on the device side and a corresponding mobility information is generated. Rigid mobility restrictions are also possible through the Manufacturer of the device, for example, to be an inexpensive Acquired device with regard to its uses as a purely stationary device in the sense of a fixed connection or as a device that can only be carried on foot with a small device limit the permissible movement speed.

Conditions can also be specified on the network side, for example, with high network utilization in the form that the station on the subscriber side then only accesses certain services are released when the subscriber side Do not station yourself or only within a very narrow range Mobility limits moved. Ultimately, the network operator can Impose restrictions comparable to those of Equipment manufacturer.

Advantageously, in the subscriber station one to be taken into account from now or in the future Mobility information saved permanently or temporarily. In particular, it is possible with permanent storage a maximum permissible mobility is also a temporary one Restrict mobility to an even more limited one To store the mobility area in a further storage area, the station on the subscriber side being the lowest permissible mobility information as a criterion for operation attaches.

In the event that the station on the subscriber side mobility limits set or exceeded threats, a warning function can be activated, which the Participants at the risk of disconnection or the Draws attention to the risk of a restriction of resources. If such a warning is not provided or ignored, then the connection is expediently terminated or accordingly on a limited available resource switched.

An apparatus for performing such a method expediently has a transmission and / or Receiving device, via which, in addition to actual user data Information on how the mobility information is transmitted can. In addition, the one that is usually available Device memory with a storage space for mobility information designed. Ultimately, the functionality of the Control device necessary routines required for Management of procedures and associated applications be used.

The approach is based on situations in which it in terms of for a subscriber side station there are required mobility restrictions. The restrictions can arise, for example, from the fact that a mobile station is actually installed stationary and one Mobility is not necessary or not possible at all. Restrictions or restrictions can also result from this reveal that a subscriber-side station is only used by people is carried, which only move on foot, which is why only a speed range with very low ones Speeds must be taken into account. Are also conceivable stations on the participant side, which are temporarily slow or not moving at all and at other times in one Car be carried, the participant of such Station the speed requirements or Knows mobility requirements for the next period of use. stationary Stations can be a static terminal, for example, which is used as a wireless local connection (WLL - Wireless local Loup) a previously common telephone landline connection replaced. Fixed stations can also be static, for example Measuring stations, which are current measured values via a Send the mobile network to a monitoring center.

Another approach starts from the network side and takes into account, for example, situations where the danger an overload for the communication network due to a very large number to be supported at the same time stations on the participant side. In such situations are fast moving stations on the subscriber side, i.e. stations with a particularly high demand on network resources, not or only limited by the communication network maintainable. It may therefore be in the interest of the network to have such Stations not or only with defined restrictions support.

By implementing such methods and devices there is a surprisingly large number of advantages.

The fact that the network-side and subscriber stations before establishing a connection or in Information about the current connection Being able to exchange planned or permitted mobility is one more accurate prediction of cell load fluctuations possible what of the algorithms for load control and also from the algorithms for admitting additional ones Stations can be used. While uncertain Mobility on the network side must assume that for everyone subscriber-side stations suddenly movements with higher Speed can be managed if you are aware of a A large number of stations on the subscriber side with only minor or no movements at all on the network side Participant stations for setting up Communication connections are allowed.

In the event that it is known on the network side that a station on the subscriber side cannot move or moves slowly the network-side administrative effort for this station is strong be reduced. For example, algorithms for Determination of the current location (location updates) and algorithms for preparing transfers to others Correspondingly, radio network cells (hand over) either not or only be performed less often. In the event of carrying out a Determination of the current location of a station on the subscriber side, a more specific station search (paging) be carried out since the whereabouts of the subscriber-side station with a view of a single cell or a limited environment around a particular cell is known.

In communication systems with a hierarchical Hierarchical Cell Structure (HCS) environment is one improved allocation of stations on the part of the participants Cells of such an environment possible, including one improved prediction of the load in the individual levels of the Cell structure is possible.

If it is known that a subscriber station is not moved or only moved to a very limited extent, it is also possible that Parameters of the radio channel by averaging over a much longer period than usual determine, so that these are then determined more precisely can. With such more precise values is then a more optimal one Calculation of coefficients for driving z. B. one adaptive antenna field possible. This also does use of improved mechanisms for adaptive Antenna fields, for example so-called smart antennas, are possible. If it is known that the location is a station has not changed or has changed only to a limited extent, is at Connection establishment also no power-up (ramp-up) in random access required because it is known from previous access attempts which one Initial power is required for the network side Station the connection request with sufficient performance receives. In the case of stationary or static subscriber-side Stations can ideally be the least necessary Initial power can be used. In addition to the Interference on the radio interface also the load in the network side station and ultimately reduced the time for the establishment of the RRC connection (RRC: Radio Resource Control) shortened.

Also in the opposite direction, that is from one network-side station to a subscriber-side station can with least required power to be sent if on the network side it is known that the subscriber side Station has not been on the network side since the last transmission Station has removed.

Fixed or moving only in a limited space Subscriber stations are also considered reliable Relay stations can be used. Take as an example Mechanisms like ODMA (Opportunity Driven Multiple Access) cited where it is possible to be participant-side Stations as relay stations between a network-side station and other more distant subscriber stations use, thereby extending the coverage area View of a stationary station is made possible. Since it is in such relay stations on the one hand sending and on the other hand, receiving stations, the concept can also generally two, a first and a second with each other communicating stations are expanded.

Fixed subscriber stations are also local Measuring units (LMU - Location Measurement Unit for Localization services (LCS-LoCation Service) can be used. Here results there is also the possibility that the participant Stations or the participants assigned to them Discounts or credits can be granted if they are Network operator or its stations during the measurement of network parameters, especially positions of others help stations on the participant side. Improved network planning is particularly possible if information about the Number and, if applicable, the location static subscriber stations are known or via a Period can be determined.

It is advantageous for stations on the subscriber side that are stationary or moving at only limited speeds up to 50 km / h for example, also the use of Operating modes and procedures possible, which one Transmission power reduction at stations with low Effect speeds. In the case of UMTS as a communication system for example, a special broadcast diversity that So-called closed loop mode 2 TX diversity, can be used.

Procedures for cell selection and cell reselection can be executed less frequently or switched off completely if it is known that a subscriber station is not or only moved in a limited space. such Procedures (Cell Selection, Cell Re-Selection) can be done at subscriber stations are switched off accordingly, what to reduce the signaling load and one Reduction in the number of stations required in the subscriber station Leads measurements and thus the battery consumption in the subscriber station reduced. In the event that in the subscriber station special algorithms for Monitoring the speed or the transmission process at Speeds performed above a threshold speed be, it is possible to add such procedures in the Procedures of cell selection and cell reselection turn off what also to a reduction in measurements or one Reduction of the computing effort in the corresponding participant station leads.

In the case of hierarchical cell structures, one can be fixed or moving only very slowly or moving very slowly a frequency can be assigned to the station on the subscriber side, their path loss to the next network-side station is low is. For this purpose, for example, an RRC measurement, z. B. the so-called measurement event 2a (event 2a), be used, which indicates when the most suitable Frequency has changed and a change makes sense. The corresponding event criterion can be used for each set a short time to the system capacity make optimal use of it and increase the quality of service.

Mobility information can also be used when determining RRC states are used. One is slow moving subscriber station that is only inside a limited environment or at least only with a very low speed of, for example, a maximum of 5 km / h moves, for example, it is not necessary that subscriber station in the so-called URA_PCH state switch, where URA_PCH is a UMTS-specific state in which the position of the subscriber station UE on the level of the UTRAN location area is known. This can reduce the load on the system otherwise through a more complex search for stations (paging) arises.

There is also a handover control Reduction of effort required, because with one subscriber-side station that is stationary or only inside moving in a restricted environment, no measurements Neighbor cells of the current or another frequency (intra- or interfrequency measurements) must be what the measurement effort in the corresponding subscriber station reduced.

There are also advantages with bit rate allocation (bit rate allocation). Subscriber stations that are close a station on the network side can be without Loss of capacity can be assigned a higher data rate. Have the network-side stations and facilities knowledge, for example through a localization service or measurements that yourself a subscriber-side station near the network-side station is located and the station on the subscriber side is not moving, a higher data rate or an AMR Operating mode with higher rate (AMR: Adaptive Multi Rate) assigned as this with the same cell load for subscriber stations in the cell edge area would be possible.

Mobility information is also advantageous in connection Can be used with RRC connection mobility procedures. As a general rule Such procedures can be carried out at stations on the participant side, which are stationary or only within a limited area Moving space can be reduced to a minimum what the required signaling and ultimately the Energy consumption minimized.

A reduction in the power control cycles (Power Control Cycle) is also possible if it is known that one or more stations on the subscriber side not or only within certain local or speed limits move.

The above advantages result from the utilization of mobility information with knowledge of only one limited or nonexistent mobility among participants Stations. The mobility restrictions can can be specified on the participant side, but can also on the part of network-side stations imposed on the subscriber-side stations become.

At first glance, the one described contradicts Procedure, the usual idea to set up and operate a Radio communication network, which is based on a principle Unrestricted mobility as an always sought-after characteristic is designed against fixed networks. As if from the advantages can be seen, but is just by such a permanent or temporary restriction of individual or mobility optimization of all communicating stations Network resources enabled.

Exemplary embodiments are described below with reference to the drawing explained in more detail. Show it:

Fig. 1 is a subscriber-side station which notifies a network-side station without prompting mobility information;

Fig. 2 is a subscriber-side station which notifies a mobility information to the network on request;

Fig. 3 shows a subscriber-side station, by a mobility limitation is imposed on the network;

Fig. 4 shows a plurality of subscriber-side stations, which mobility information is transmitted by the network, and

Fig. 5 is a diagram of the distribution of mobility information within a communication network and to external devices.

As can be seen from Fig. 1, a communication system consists of a variety of different types of devices. At the subscriber end, there are stationary or mobile subscriber end stations UE, for example mobile radio telephones or computers with radio interface cards. These subscriber-side stations UE communicate via radio interfaces V with network-side access stations NB, which are also referred to as base stations or node B. The radio interfaces V can be set up within a coverage area of a radio cell Z, one or more such radio cells Z being able to form around the antennas of an access station NB.

On the network side there are one or more such access stations NB with a radio network control device RNC (Radio Network Controller) and connected to other network devices. As an exemplary network, UMTS Mobile radio system outlines a transfer to others However, networks such as GSM or pure data networks implemented.

Advantageously, when establishing a connection V between a subscriber station UE and a network-side access station NB a mobility information MC be replaced. But alternatively or additionally the transmission of mobility information MC (Mobility Class) possible during an existing connection V.

A particularly easy to use mobility information MC is based on a standardized classification Mobility classes MC-1 described below. , , MC-7 possible. For example, mobility information is also discrete Measured values from a continuous spectrum can be used, individual spectral ranges then advantageously can be assigned to individual mobility classes. While fixed mobility classes expediently should be standardized, the use of would not be fixed given mobility class identifiers even without a fixed one Standardization is easy to use.

A mobility classification is advantageously carried out by characterized various statements, in particular by a maximum permissible or maximum possible speed, with which can move a subscriber station UE, and / or through a maximum spatial movement space, within which a subscriber station UE is moving can. With a view to the spatial movement space of the subscriber-side station UE can in turn be broken down be made. Criteria for such a breakdown can, for example, a maximum possible movement of the subscriber-side station UE from a specific location, a relative possibility of movement of the participants Station UE within a predetermined period of time and / or a spatial possibility of movement of the participants Station UE within a specified area, for Example within the indoor environment of a certain building or complex of buildings.

An exemplary tabular classification in mobility classes MC-1-MC-7 can be structured as follows:
MC-1: User-side stations UE, which are static or do not move away from their location, are assigned to a first mobility class MC-1.
MC-2: User-side stations UE that can or are allowed to move at a speed of, for example, up to a maximum of 5 km / h and that can or can only move within a predetermined environment, for example a building area, become a second Mobility class assigned to MC-2.
MC-3: A third mobility class MC-3 is assigned to subscriber stations UE, which can or may move at a limited low speed, for example a maximum of 5 km / h, but are not subject to any restrictions with regard to spatial movement.
MC-4: A fourth mobility class MC-4 is provided for a medium limited mobility, for example subscriber stations UE, which can move at a higher speed up to 50 km / h, for example, but are also limited to a certain area ,
MC-5: A fifth mobility class MC-5 represents medium mobility, so it is used, for example, for a user-side station UE, which can or may move at a higher speed of, for example, a maximum of 50 km / h, for example, without a spatial restriction.
MC-6: A sixth mobility class MC-6 represents a standard mobility that can be used sensibly for conventional mobile radio telephones as a stationary station UE. Usual conditions correspond to a lack of spatial limitation and maximum speeds of, for example, 120 km / h.
MC-7: A seventh mobility class MC-7 is used for unlimited mobility, in which a subscriber station UE is not subject to any spatial or speed restrictions. This seventh mobility class corresponds to the situation currently considered in all procedures and requires the provision of a large amount of resources.

The mobility restrictions or the assignment of Mobility classes can be done in different ways. On the one hand, a subscriber station UE can have a fixed one and cannot be assigned to a changeable mobility class. On the other hand or alternatively, a mobility class of subscriber-side station UE but also assigned as required become. This assignment can be made on the subscriber side, that is, by the user of the station on the subscriber side manually or automatically by an activated service be specified. The assignment can also be made on the network side, for example on the part of the network with high network utilization one or more of the subscriber stations UE one assign maximum or fixed mobility class.

The mobility information or the mobility class is thus information which is an information element between subscriber-side stations UE and network-side stations NB is exchanged. The exchange of information can be done in existing news or new standalone Messages between the subscriber stations UE and the network-side access stations NB are carried out. In particular, such information is also between individual network devices within the communication network replaced.

The exchange of mobility information can be based on the Connection V between a single subscriber side Station UE and the network-side communicating with it Access station NB may be limited, the network side Access station NB at the same time also communication connections V entertained to other subscriber stations UE can. Alternatively or additionally, one is also possible Transmission of mobility information MC, MC-1-MC-7 via a large number of interfaces V on the network side Access station NB to all or more of those using this communicating stations UB.

With a view to the concept of the environment There is another possibility of subdivision according to the type of environment. In addition to the division into one individual or a group of radio cells Z, which over certain properties to be defined on the network side other classifications are possible. For example, a distinction can be made between an environment with Conditions that apply to an operation exclusively within a building or part of a building (indoor environment), and conditions outside of Buildings (outdoor environment). Additionally or alternatively can also be broken down into rural conditions Areas (rural environment) and urban areas (urban environment).

Since in a typical cellular communications network UMTS Environment is assigned to one or more cells Z and that Net controls the cells or the movement of Participant-side stations UE in the radio cells Z and can restrict, the communication network or Communication system consequently also has control over the above listed environments and environment types.

In the exemplary embodiment shown in FIG. 1, the subscriber-side station UE notifies the network or the network-side access station NB of its mobility class or the corresponding mobility information. This can be done during the establishment of a connection or during an existing connection, the latter especially in the case of operational changes or cyclically. Operational changes are present, for example, if the subscriber station UE wants to change from a mobility class MC-1 for stationary operation to a mobility class MC-2 for operation with a permissible slow locomotion. Operating conditions that require a change in the mobility class may also exist due to the service.

In the event of one by the user of the participant Station UE cannot change mobility information or Mobility class this can be preferred in the participant or the unit identifying card (USIM: Universal Subscriber Identity Module) saved or temporarily by the communicating network.

In the case of one by the user the participant Station UE changeable mobility information or Mobility class can change in a memory of the subscriber side Station UE can be stored. There is also an additional one general limitation in the way possible that the user can only choose between certain mobility classes, for example only up to a medium mobility or mobility restricted to a specific area can dispose of.

It is advantageous to limit mobility by the subscriber-side station UE with a network-side Linkable charge function. For example, one can only low charge for fixed subscriber-side UE stations are applied while paying the fees due increasing mobility. Such Fee linking offers the advantage that participants who need only limited mobility with a view lower fees a correspondingly low mobility class select and thereby ultimately the participant fees spared and on the other hand a relief on the network side in favor of communication with other participants Stations UE is made possible. The participant can thus its subscriber station UE directly or manually automatically a desired or required mobility pretend.

In particular, the required mobility class can also determined by the user-side station UE itself not only depending on the service, but also on the basis of recorded measured values. For example, the subscriber station UE based on the received transmission power of a Broadcast channel of the communicating network-side Access station NB find that they are relative to this stationary access station NB moves. Based on this collected data a speed can be determined so that the subscriber station UE based on the determined Speed automatically a minimum required mobility class determine and to the network-side access station NB can transmit. Other ways to identify the Change of location or speed are also possible. For example, the subscriber station UE can use a so-called GPS module (GPS: Global Positioning System) feature.

The network-side stations and facilities can be on Mobility information received in a variety of ways react. In particular, an active assignment of Resources to the communicating subscriber station UE or other stations possible.

As can be seen from FIG. 2, in which the same devices are shown as in FIG. 1, according to a further embodiment, the network can also query the mobility information or mobility class, that is to say via the network-side access station NB. The option that the access station NB queries the mobility class MC and then receives its current mobility information or mobility class (MC = X!) From the communicating subscriber station UE is advantageous, for example, in transition periods in which only individual access networks and subscriber stations UE are included a functionality for the transmission of mobility information, so that the transmission of mobility information that cannot be used by other access networks is suppressed in these transition periods.

From Fig. 3, an embodiment is shown, in which at the same station assembly as shown in Figs. 1 and 2 from the access network or its access station NB via the interface V mobility class statement (MC = x!) For a given or a maximum mobility class to the station UE is transmitted. In addition to the possibility of addressing the subscriber-side station UE directly through the access station NB via a direct and unambiguous communication link V between these two, there is also the possibility of transmitting such instructions via radio channels, in particular so-called broadcast / multicast channels. It can also be determined by standardization or by explicit instructions whether the dedicated communication of the mobility class from the access station NB to the subscriber-side station UE should only apply for a certain period of time and / or only for a certain radio cell Z.

If there is already one in the subscriber station UE Mobility information or mobility class MC-1. , , MC-7 is saved, this value is replaced by the specified one Information overwritten. Alternatively or additionally are also Embodiments possible in which the original Obtain information in this or another memory area remains to be given after the omission of the network side Mobility class, for example, in the course of time original condition with the original, e.g. B. to be able to switch down the mobility class desired by the subscriber.

As can be seen from FIG. 4, in which further subscriber-side stations UE, UE 'and a further network-side access station NB for supplying a separate radio cell Z' are shown, such network-side instructions for using a maximum mobility class (MC = y!) Can not only be used a single specific subscriber-side station UE, but rather to several or all stations UE, UE 'in a radio cell area Z, Z'. In particular, different permissible mobility classes can be assigned in different radio cells Z, Z '(MC = y! Or MC x!). The assignment of different mobility classes or no mobility restrictions for certain of a plurality of subscriber stations UE, UE 'can also be implemented.

The time at which the access network or Mobile network UMTS a certain or a maximum Mobility class MC for one or more subscriber stations UE, UE 'is set is corresponding for the dispatch Dedicated messages can be freely selected. In particular can send such messages during connection establishment or also in the course of an existing connection V, V ' be transmitted. For the transmission of such messages in addition to dedicated connections V, V ' Broadcast channels are used. The transmission of the Mobility information or mobility class can thus be done while one or more subscriber stations UE a Have established connection to the radio cell Z, Z 'in which the Broadcast information or broadcast / multicast broadcast become. The notification of mobility information or Mobility class can also be done while a participant Station UE has not yet established a connection V to Mobile network has, but already over a broadcast channel can receive appropriate information.

There are also communications related to mobility information or mobility classes, while one subscriber-side station UE 'a dedicated connection V' to one Cell Z 'has built up, but broadcast messages a other listening cell Z can listen. That possibility is particularly advantageous if there is a subscriber-side Station UE 'is in a cell Z', in which only one low mobility class permitted for data transfers is, this subscriber-side station UE 'is in the Overlap area to the other cell Z is located in which imposes less or no mobility restrictions and in which the subscriber station the Data connection V can change.

In the first of the latter three cases, there is an immediate one Validity of the assigned mobility class MC makes sense, unless required by standardization requirements or a with transmitted time for the validity a later one Switch to the assigned mobility class is. In the other two cases, the mobility class Assignment expediently valid as soon as the subscriber-side station UE 'a connection V' to the sending cell Z ' has built up. A later activation of the assigned mobility class status possible if for example corresponding additional time information for the scope of the mobility class assignment were transferred.

Advantageously, both the subscriber side Station UE as well as the communication network UMTS or its Restrictions assigned to access station NB, in particular restrictions imposed by the network Check mobility classes. For example, information about this from speed measurements, movement measurements by means of Evaluation on the part of the user station UE and / or Movement measurements by the access station NB or this higher-level stations RNC are performed.

As can be seen from FIG. 5, the mobility information or the information about assigned or required mobility classes can be transmitted and evaluated within the various network-side devices and stations. In addition to the illustrations of the above figures, the mobile switching centers MSC (Mobile Switching Center) and / or a serving FIG. 5 shows a connection of the radio network controller RNC to other radio network controllers RNC, external devices, GPRS support nodes SGSN (Serving GPRS Support Node) (GPRS: General Packet Radio Service). These different stations can in turn be interconnected. In particular, connections to a visitor location register VLR (visitor location register) and a home location register HLR (home location register) can also be switched. On the part of the serving GPRS support node SGSN, a packet data connection to another network, for example a network under the control of the Internet protocol, can also be set up via a gateway GPRS support node GGSN.

Information about a predefined or restricted mobility or mobility class MC as well as derived information for example statistical purposes or controls certain Network functions can be distributed in the UMTS communication network. Aim this Information distribution can be, for example, the Administrative control in the access network of the UMTS communication network which improved with the help of this information Resource allocation determined. Forwarding is also possible such information to external institutions, for example at network maintenance terminals, Position control units (HLR, VLR or Packet networks.

The information of the mobility classes can by the UMTS communication network used in various ways become. This includes in particular information about the Mobility classes MC for a specific one or more subscriber-side stations UE, derived information that for Example statistics about the mobility class distribution in include a cell Z, or combined information, at those of the mobility class or mobility classes with others Information can be used in combination.

This makes it possible in particular to optimize the radio and cellular network internal resources. Processes can also within the communication network or cellular network as well can be optimized on the radio interface V. In this regard, is especially the reduction in the frequency of measurements cited which is for a static subscriber-side Station UE are needed to a lesser extent than for mobile or fully mobile subscriber stations UE.

When providing services depending on the Mobility class can be a static subscriber station UE, for example, when resources are required for reduced an error correction also allocated a larger bandwidth as a mobile subscriber-side station UE. It is also possible to restrict the provision of one Service with high quality requirements on lower ones Mobility classes if the required level of service in the case a fully mobile subscriber station UE is not could be achieved.

In general, the reliability of services increases. Becomes for example for the provision of a service of actual location of a subscriber station UE important, the information represents that this subscriber-side station UE is static or stationary, ensure that this service after a one time determination of the Location always provided in a reliable degree can be.

In particular, it is also a combination or cooperation can be set up advantageously with charging facilities. This can create an incentive with a view to Depending on the class, there is a lower charge for mobility classes and thus resources only to the extent actually required occupy.
