METHOD AND APPARATUS FOR SENDING MEASUREMENT REPORTS IN A RADIO COMMUNICATION SYSTEM

The invention relates to a method for operating a Funkkommumkationssystems, m which a plurality of mobile stations residing in one cell. The invention also relates to a radio communication network, an instance in the radio communication system, a proxy server, a mobile station and a proxy mobile station and a base station having means for carrying out the method.

Reports on measurements (measurement reports) represent a significant portion of the total load within a radio cell. To support functions such as hand over, link adaptation, power control, etc. However, they are inevitably necessary.

The invention has the object of providing an efficient

A method of operating a radio communication system re duced on ¬ ¬ zuzeigen, which caused the total load in a radio cell, inter alia, by so-called measurement reports. Furthermore, devices are to be identified for carrying out the method.

This object is achieved by a method and apparatus having the features of the independent claims. Advantageous embodiments and further developments are characterized by the dependent claims.

Due to a special scenario own sheep ¬ th some mobile stations can be almost identically.

Example scenarios: subway,

- train,

- Hot-Spot, et c.

Em aspect of the invention resides in a method of operating a radio communication system in which a plurality of persons present in a radio cell mobile stations are assigned to the characteristic of a common group. Such mobile stations are assigned to a group when the exchange of the respective mobile stations with the Funkkommunika ¬ tion system information to each other in their properties in correlation.

The invention also relates to a Funkkommumkati- onsnetz, an instance in the radio communication system, a proxy server, a mobile station and a proxy mobile station so-as a base station having means for carrying out said method.

Zukunftig eg in railway stations and on trains also called (WLAN) hot spots be available. Can receive the hot spot on the train, a mobile station, but the hot spot of the station not received, then it should be ensured that the mobile station is in train. Thus, HO can customize location update, channel estimation well to changing Gege ¬ various high. For this purpose advantageously carried out the supply order of a mobile station to a group when they receive certain signals or may maintain a connection with another communications network. Reverses defines a mobile station may be assigned to a group advantageously when they do not receive certain signals, or can not maintain connection with another communications network. In the specific signals, it may preferably be a so-called CPC (Cogmtive / Common Pilot Channel), as has been proposed, for example in EP 05027892.8. Definition of the group:

A group is defined by its physical and non-physical properties. These could be lower alia, the following parameters or a value derived therefrom combination of parameters: for example,

current position - RSSI - Level - interference level speed required data rate achievable data rate required QoS (Quality of Service, including delays) - guaranteed QoS - Level maturities (distances) supported services specific routes, geographical proximity simultaneity of events (HO)

In principle, this is the proposal is a predictor tion based on measurements / requirements from the past. One should therefore only summarize mobile stations in a group when the measurement reports of mobile stations were strongly correlated over a 'long' time. From this it is close to a correlation for the future, allowing only act to have some mobile stations representative. A mobile station can belong to multiple groups. It can accommodate groups with different parameter combinations and weightings exist simultaneously.

Note on routes:

Such routes may be defined using sequences of HO-cells. Promising routes for groups from the viewpoint of HO are railway or subway lines. Roads and highways are less suitable for HO groups. Although many participants place with mobile stations back the same distance aller- recently distributed at different speeds and continuously over time. Here the group can only be used to control the measurement reports, actions can not be derived from it.

Construction / initiation of a group or access a mobile to a group:

Variants :

Request by mobile station

The mobile station is similar to its properties from those of the group. If at least one of (or parts or all) group of properties is met (are) the requirement is transmitted tion for group membership. Mesh side / base station can then confirm accession (ACK). In case of rejection, it can be transmitted. The number of requests should be limited. The interval between the request can vary.

Allocation on the base station or subsequent instance (in this central entity)

The mobile station reports measurement reports to a central ¬ rale instance. Is the central authority determines that one of (or parts or all) group property (s) is satisfied (are) determined, the allocation to this group is signaled to the mobile station. The mobile station should acknowledge this message. In Nichtbestatigung the message can be sent repeatedly. The interval be- see the Signalisierungsnachπchten can be varied (see above).

Based on identical Reports

Reports more mobile stations identical conditions with regard to one or a number of parameters, these can be summarized as a group. Receipt of certain signals or networks, if any, of the receipt of an ICE-Fi's the easiest way mobile detect the presence of a train. However, other mobile Ubertra- gungstechmken such as blue tooth etc. conceivable.

Measurement reports of the group:

The measurement reports of the radio cell can be reduced with the help of the group without the condition description of the radio cell or the individual mobile stations significantly degraded.

To this end, there are several possibilities:

Initiation by a central instance

The network side selects the mobile stations for the measurement report. The selection is transmitted to the mobile stations. A default would be in this case, no report to generate (inversion of this principle is possible). For the sake of fairness (power consumption, etc.), the measured mobile stations should be 'replaced' from time to time.

- Decentralized mechanisms / initiation by Mobile

For example, network side determines the rate for reports and a fixed probability (the more mobile of the group m is smaller the rate). Mobiles generate their reports at random. Frequency is determined by a Wahrschemlichkeitsparameter. The Wahrschem- lichkeitsparameter must be signaled.

Measurement reports of individual mobile stations of the group:

The central entity disposes of the possibility of a corresponding signaling reports of individual Mobilsta ¬ functions on or off (optional). Announcement of the group properties:

3 variants are possible:

- Dynamic: current group properties to the mobile stations via signaling central instance (preferably broadcast repeatedly, preferably periodically) over ¬ averages.

Static:

Group properties during the existence of a group set. Here, it is sufficient for allocation to a group properties stuffs to ubermit- to the mobile station.

Special case: standard groups. The properties of these groups are, for example, defined by the standard.

Quasi Static: As indicated above, in the case of static, but at a Eigenschaftsanderung this is additionally transmitted to the mobile stations via signaling.

Outlet individual mobiles from the group:

A mobile station must leave the group when at least one group property (or parts or all) is not more he ¬ filled.

According to the entry into the group results in several variants:

The mobile station is similar to its properties from the Properties group. In "injury" of the properties of a request for an outlet to a central instance is transmitted. Optionally, the self-ursachliche ¬ shaft or a value which can be supplied to the central entity. The decision on leaving the group-PE can then from the central instance to be taken. The mobile station is informed of a signaling.

As stated above, however, the mobile station informs only the central authority of its exit. The decision falls the mobile station.

As stated above, however, the mobile station does not make any selection, but initiated independently only own MEA surement reports. These are repeated until a reac tion of the central entity ¬ takes place. (Such as "Exit group 'or' spot Reportmg a ')

Elimination of the reception of certain beacon signals or networks.

Dissolution of the group

The central entity may be via a signaling make the solution Auflo- the group known (optional).

Peer-to-Peer (point-to-point) communications:

The invention let advantageously combine with a point to point communication between locally adjacent Mobilsta- functions. Here is a proxy mobile station was able to gather, process the measurements of the neighbors and forward it to the central authority. The same is true for the signaling in jerk direction. The proxy mobile station appears here as a kind of group spokesman on. Logically, this function is allocated by the central entity.

Enhancements to protocol and data services:

Previous VERSIONS was based on the idea to reduce the effort for the measurement reports. But also log data and data services can smnvollerweise by a group that has been formed in accordance with the rules listed above, are supported.

Examples: - HO @ Zugszenario. Relative addressing of the resources m the new cell. Here are just a is transmitted "vector", which determines the offset of the old to the new resource. In the simplest case this is for all Mobilstatio nen same. Per HO is thus the transmission of vector-tors to the whole group is sufficient. For some Mobilsta ¬ tions of the group, it may be interesting to separately provide a dedicated, new 'resource (absolute or relative) to ver ¬, that overrides the relative addressing the group. a suitable resource management (m of al th and new cell) to group HO here under clip (eg Bundein of group members in resource blocks and releasing corresponding resources m the new cell). same applications for members of a group (MuIti- Cast) (football match in which followers of a club with a parallel soccer game Ex. on want to be kept informed) addressing for the multicast (for IPV4. 4 bytes per packet) can here (in the group address some bits per packet) r be eduziert. In a decimal all official allocation of the resource for the group can be dispensed with an address.

The measurement reports of a radio cell can with the help of

Groups are reduced without significantly degrading the state description of the cell or of the individual mobiles.

It is also achieved a higher efficiency of the air interface of Ie by reduction of the signaling overhead. That go with a reduction of inter-cell interference and increase capacity. the one relates to the

Group parameter to inter-frequency or inter-RAT observations, the reduction of the interference is particularly efficient, since such measurements are always wall with a raised up are connected. If you have formed local groups, this information is also known as MU-MIMO Algorrthmen or generally for so-called scheduler of interest, since it orthogonal groups can be detected, ie preferred mobile stations len to schedu- from different groups.
