Definitions
- the invention relates to a method for assigning radio resources to radio stations of a radio communication system, in which messages are transmitted between radio stations by forwarding these messages via other radio stations. Furthermore, the invention relates to a radio device for performing the method.
- messages such as voice messages, messages with image information, video information, SMS (Short Message Service), MMS (Multimedia Messaging Service) or other data
- the radio stations can be different types of subscriber-side radio stations or network-side radio stations such as radio access points, repeaters or base stations.
- the subscriber-side radio stations are mobile radio stations.
- the electromagnetic waves are emitted at carrier frequencies which lie in the frequency band provided for the respective system.
- Mobile radio communication systems are often described as cellular systems e.g. according to the standard GSM (Global System for Mobile Communication) or UMTS (Universal Mobile Telecom unications System) with a network infrastructure consisting e.g. formed from base stations, devices for controlling and controlling the base stations and other network-side devices.
- GSM Global System for Mobile Communication
- UMTS Universal Mobile Telecom unications System
- WLANs wireless local networks Networks
- AP Access Point
- WLANs wireless local networks Networks
- the cells covered by the wireless access points (AP: Access Point) of the WLANs are small with a diameter of up to a few hundred meters in comparison to conventional mobile radio cells. Examples of different standards for WLANs are HiperLAN, DECT, IEEE 802.11, Bluetooth and WATM.
- the unlicensed frequency range around 2.4 GHz is used for WLANs.
- Data transfer rates are up to 11 Mbit / s.
- Future WLANs can be operated in the 5 GHz range and achieve data rates of over 50 Mbit / s. This means that the subscribers to the WLANs have data rates that are considerably higher than those offered by the third generation of mobile communications. This means that access to WLANs for high-bit-rate connections is advantageous for the transmission of large amounts of data, especially in connection with Internet access.
- the WLAN radio access points can be used to connect to other communication systems, such as the Internet.
- the subscriber-side radio stations of the WLAN either communicate directly with a radio access point or, in the case of more distant radio stations, via other radio stations, which forward messages between the subscriber-side radio station and the radio access point.
- the available, generally scarce, radio resources are shared between the radio stations of the WLAN or are divided among the radio stations of the WLAN. If the division takes place, for example, in such a way that radio resources are largely available to a first radio station transmitting messages, while radio resources are scarcely available to a second radio station transmitting messages, traffic jam, overloading of the second radio station, and eventually result in a loss of news.
- the invention is based on the object of demonstrating an efficient method for assigning radio resources to radio stations of a radio communication system, in which message transmissions between radio stations are carried out by forwarding these 5th messages via other radio stations. Furthermore, a radio device for assigning radio resources to carry out the method is to be presented. This object is achieved by a method with the features of claim 1 and by a radio device with the features of claim 10.
- the method according to the invention is used to assign radio resources to radio stations of a radio communication system.
- messages are transmitted between radio stations by forwarding these messages via other radio stations.
- a radio device receives request messages from radio stations to request an allocation of radio resources for the transmission or forwarding of messages.
- the radio device assigns radio resources to radio stations which have requested the allocation of radio resources, taking into account the classes of these radio stations. Furthermore, she informs about the assignment by at least one message.
- the radio stations of the radio communication system can, for example, be radio stations Trade WLAN, in the form of, for example, subscriber-side radio stations, relay stations and radio access points.
- the radio device can be, for example, a base station of a cellular radio communication system.
- Each radio station of the radio communication system which takes part in the transmission of messages via radio, belongs to one or more classes.
- the classes refer to the function of a radio station in the transmission of messages. It is possible that identically designed radio stations belong to different classes. If a radio station belongs to several classes, the radio device can recognize from the request of this radio station for radio resources in relation to which class this request is made. It is possible that the affiliation of a radio station to one or more classes changes over time.
- the radio resources which the radio device assigns to the radio stations may e.g. around one or more radio frequencies, e.g. OFDM bands act, and / or time slots and / or codes and / or spatial directions.
- radio frequencies e.g. OFDM bands act, and / or time slots and / or codes and / or spatial directions.
- the assignment of a combination of time slot and radio frequency is particularly advantageous.
- the assignment of radio resources by the radio device takes into account the classes of radio stations. This can e.g. can be realized by prioritizing different classes and
- Allocation of radio resources according to an order of prioritization For example, it is possible to assign radio stations of a lower priority class only when there are no radio stations of a higher priority class to which the requested radio resources are not assigned.
- the consideration of the prioritization can be restricted to certain radio resources, for example a different prioritization can take place from radio resource to radio resource, and also to certain radio stations, for example the consideration of a specific prioritization can only take place with respect to radio stations of a certain geographic region.
- After successful Instruction informs the radio device of this assignment.
- the transmission of a message with information about the assignment can be sent by the radio device to all radio stations, or only to those radio stations to which radio resources are assigned and / or to radio stations which subsequently forward the information about the assignment to other radio stations.
- radio stations of a first class of radio stations forward messages received from radio stations to other radio stations for forwarding the messages.
- This can e.g. are repeaters or relay stations which do not introduce any new messages into the radio communication system, but instead forward messages already brought into the radio communication system from other radio stations.
- the radio stations of the first class can in particular be network radio stations.
- radio stations of a second class of radio stations forward messages received by radio stations to the radio stations to which the respective message is addressed. This can e.g. are repeaters or relay stations which do not introduce any new messages into the radio communication system, but instead forward messages already introduced into the radio communication system by other radio stations.
- the radio stations of the second class can in particular be network radio stations.
- a radio station can belong to the first and the second class of radio stations; their class affiliation with regard to a specific message then depends on the radio station for which a message received and to be forwarded is intended.
- radio stations of a third class of radio stations forward messages received from another communication system to radio stations for forwarding the messages.
- Third-class radio stations can be, for example, radio access points of a WLAN with a connection to the Internet.
- the other communication system can be designed as a radio communication system.
- the radio stations of the third class can in particular consist of network radio stations.
- radio stations of a fourth class of radio stations forward messages received from another communication system to the radio station to which the respective message is addressed.
- Fourth-class radio stations can e.g. around
- the other communication system can be designed as a radio communication system.
- the fourth class radio stations can in particular consist of network radio stations.
- a radio station can belong to the third and fourth classes of radio stations, their class membership in relation to a specific message then depends on the radio station for which a message received and to be forwarded by the other communication system is intended.
- radio stations of a fifth class of radio stations send their own messages to radio stations.
- a message of its own is a message that was not received by another radio station for forwarding, but is newly sent from the radio station to the radio communication system.
- the fifth-class radio stations can in particular be subscriber-side radio stations. It is advantageous if classes are taken into account when allocating radio resources in such a way that time slots are allocated for a radio frequency in accordance with a prioritization of radio stations in the sequence: first first class, then third class. In this case . all or at least some of the radio stations of the first and third class use the same radio frequency.
- the radio stations of the first class are preferably dealt with in the allocation of radio resources, that is to say those radio stations before an existing one in the radio communication system
- classes are taken into account when allocating radio resources in such a way that time slots are allocated for one or more radio frequencies in accordance with a prioritization of radio stations in the order: first second and fourth class, then fifth class.
- the second and fourth classes ie the two classes whose radio stations forward messages to the addressees of these messages, have the higher priority together.
- a distinction between the priorities of these two classes is also possible.
- the new sending of a message to the radio communication system has lower priority.
- a combination of the prioritization of the second, fourth and fifth class described here with the prioritization of the first and third class described above is also possible.
- the radio frequency or frequencies which are divided between radio stations of the second, fourth and fifth class are advantageously different radio frequencies than that which is divided between the radio stations of the first and third class.
- the radio stations of the radio communication system communicate with one another using a first radio interface and with the radio device using a second radio interface.
- the first radio interface can be, for example, a radio interface of a WLAN and the second radio interface can be a cellular radio interface.
- the radio device according to the invention is particularly suitable for carrying out the method according to the invention, and this also applies to the refinements and developments. For this purpose, it can have other suitable means. It is possible to implement the radio device according to the invention by a plurality of interconnected devices which have the respective means.
- FIG. 1 a radio communication system
- FIG. 2 schematically the content of a message sent in accordance with the method according to the invention
- Figure 3 schematically the structure of a base station according to the invention. - ⁇ •
- FIG. 1 shows a WLAN which consists of the radio access point AP, the two mobile stations MSI and MS2, and the two relay stations N1 and N2.
- the radio access point AP has a connection to the Internet INTERNET.
- the relay stations N1 and N2 are stationary, network-side radio stations which are used to forward messages between the mobile stations MSI and MS2 and the radio access point AP. Additionally or alternatively, it is possible that the forwarding of messages is carried out partially or completely by fixed or mobile subscriber-side radio stations.
- the WLAN can - not shown in FIG. 1 for the sake of clarity - comprise further radio access points, subscriber-side radio stations and relay stations.
- the message transmission between the radio stations AP, MSI, MS2, Nl and N2 of the WLAN takes place using a WLAN radio interface.
- a subscriber-side radio station is within the radio range of the radio access point AP, like the mobile station MSI in FIG. 1, it can communicate directly with the radio access point AP.
- the message is transmitted between the radio access point AP and the subscriber-side radio station by relaying the messages through relay stations.
- a message can thus be sent from the radio access point AP to the mobile station MS2 from the radio access point AP to the relay station N1, which forwards the message to the relay station N2, which forwards the message to the mobile station MS2.
- a first radio frequency is available to the WLAN, which is used for communication between the relay stations N1 and N2 and between the relay stations N1 and N2 and the radio access.
- AP is used.
- three further radio frequencies are available, which are used for communication between the relay stations N1 and N2 and the mobile stations MSI and MS2, and between the radio access point AP and the 5th mobile stations MSI and MS2.
- the three other radio frequencies are therefore always used when a subscriber radio station is involved in the communication.
- the radio stations AP, MSI, MS2, NI and N2 of the WLAN are located within a radio cell of a base station BS of a cellular radio communication system, illustrated by a cloud, such as a system according to the UMTS standard.
- the radio access point AP, the relay stations N1 and N2, and possibly also the mobile stations MSI and MS2 can communicate with the base station BS using the cellular radio interface. Since a lower radio frequency is used for communication using the cellular radio interface than for communication within the WLAN, the radio access point AP, the relay stations N1 and N2, and possibly also the mobile stations MSI and MS2 can communicate directly with the base station BS without that the messages are forwarded.
- the equipment of a subscriber radio station can communicate with the base station BS using the cellular radio interface 'does not apply, a communication between the respective subscriber radio station and the base station BS can be done via that relay station, the subscriber radio station is currently located in the vicinity thereof ,
- the mobile station MS2 could communicate with the base station BS via the relay station N2 if it is not possible to communicate using the cellular radio interface parts. If a mobile station MSI or MS2 intends to send a message, it requests radio resources for this. ?
- the message that the mobile station MSI or MS2 intends to send can consist, for example, of a request for data from the Internet INTERNET.
- the mobile station MSI or MS2 sends out a request message RR-MS (RR: Resource Request) for the allocation of radio resources.
- the request message RR-MS can either be sent directly to the base station BS, or to the relay station N2 in the case of the mobile station MS2 or to the radio access point AP in the case of the mobile station MSI, which then forwards it to the base station BS.
- a subscriber-side radio station uses one of the three radio frequencies which can be used for communication from subscriber-side radio stations.
- the relay station N2 If the relay station N2 has received a message to be forwarded from the mobile station MS2 to the radio access point AP via the relay station N1, it sends a request message RR-NN to the base station BS, which causes the base station BS to assign radio resources to the relay station N2 to send a message to another relay station. It is possible that the request message RR-N-N contains identification information of the relay station Nl. However, it is also possible for the base station BS to simply take from the request message RR-N-N that the radio resources are required by the relay station N2 for sending a message to another relay station.
- the relay station N2 If the relay station N2 has received a message to be forwarded to the mobile station MS2 from the relay station N1, it sends a request message RR-N-MS to the base station BS.
- the base station BS recognizes from the request message RR-N-MS that the relay station N2 radio resources for forwarding a message to a subscriber radio station required. It is possible that the request message RR-N-MS contains identification information of the mobile station MS2.
- the relay station N1 also sends a request message RR-NN to the base station BS in the event that it has to forward a message from the radio access point AP to the relay station N2 or from the relay station N2 to the radio access point AP. Include the request messages sent by the relay stations N1 and N2
- RR-N-N no identification information of those radio stations to which a message is to be forwarded it cannot be seen from these whether a message is to be forwarded to a relay station N1 or N2 or to the radio access point AP. This is due to the fact that the same radio frequency is used for the communication between the relay stations N1 and N2 and between the relay station N1 and the radio access point AP.
- the radio access point AP If the radio access point AP has a message received from the Internet INTERNET to the mobile station MSI, it sends a request message RR-AP-MS.
- the base station BS takes from the request message RR-AP-MS that a message from the radio access point P is to be sent directly to a subscriber-side radio station and that resources are required for this transmission.
- Identification information of the mobile station MSI can be contained in the request message RR-AP-MS.
- a request message RR-AP-N is sent to the base station BS with the content that the radio access point AP has radio resources for sending a message to a Relay station required, possibly with identification information from relay station Nl.
- Each of the request messages RR-MS, RR-NN, .RR-N-MS, RR-AP-MS, RR-AP-N described can contain information about the scope of the message or messages to be sent, so that the base station BS The request messages can tell the extent of radio resources to be assigned to the respective radio station.
- the request messages RR-MS, RR-N-N, RR-N-MS, RR-AP-MS and RR-AP-N are due to the functions of the radio stations AP, MSI, MS2, Nl and N2 of the WLAN in the message transmission. Ie there are in terms of the functions of the radio stations AP, MSI, MS2, Nl and N2 of the WLAN at • before DER messaging different classes of radio stations.
- the request messages RR-MS come from subscriber-side radio stations which do not forward messages, but send new messages.
- the request messages RR-NN originate from relay stations which forward messages received from other relay stations or from a subscriber-side radio station or from a radio access point to other relay stations.
- the request messages RR-N-MS originate from relay stations which forward a message received from another relay station or from a radio access point to the subscriber-side radio station addressed with the message.
- the request messages RR-AP-MS originate from a radio access point which forwards a message received from another communication system for a subscriber-side radio station directly to this subscriber-side radio station.
- the request messages RR-AP-N originate from a radio access point which forwards a message received from another communication system to a relay station for forwarding the message.
- the base station BS Upon receipt of request messages, the base station BS assigns radio resources to the radio stations AP, MS1, MS2, N1 and N2 of the WLAN at regular intervals. In the Deciding which radio resources are allocated to which radio station *, the Basi.ss : tation BS takes into account the classes of radio stations described above, from which it received the respective request messages. After the decision about the assignment, the base station BS sends a message informing the radio stations concerned about the assignment.
- FIG. 2 shows the structure of such an information message RESSOURCE MESSAGE sent by the base station BS.
- the first part PREAMBLE of the RESSOURCE MESSAGE message indicates that a period of time begins with a new radio resource allocation.
- the following parts inform the radio stations about "which radio resources are assigned to them.
- the base station BS sends the RESSOURCE MESSAGE message to all relay stations and radio access points to which radio resources are assigned. It is possible for this to happen that the RESSOURCE MESSAGE message is broadcast by the Base station BS is broadcast The subscriber-side radio stations to which radio resources are assigned receive the
- RESSOURCE MESSAGE message either directly from the base station BS, or by forwarding the RESSOURCE MESSAGE message or information about the radio resources assigned to it from a relay station or a radio access point.
- the first radio frequency F1 is used by the relay stations N1 and N2 and the radio access point AP, ie for all message transmissions or forwardings within the WLAN in which no subscriber-side radio station is involved.
- the base station BS thus assigns time slots to the radio stations N1, N2 and AP. The assignment takes place depending on the received request messages or on the class of the radio station requesting the radio resources.
- assigning the time slots for the first radio frequency F 1 the highest priority is given to the relay stations which issue a request message RR-NN have sent. This is followed by the access points which have sent a request message RR-AP-N.
- the assignment of time slots for the first radio frequency F1 to radio access points therefore only takes place if each relay station, before the request for the assignment of radio resources, has been allocated to the extent it requires.
- the reason for this procedure is that the messages to be forwarded by the relay stations already come from other radio stations of the WLAN and are therefore to be transmitted to the addressed radio station quickly, ie without unnecessary delay due to a long stay at a relay station.
- the news which sent a wireless access point using a request message RR-AP-N towards the assigned resources • but get from the radio access point AP new to the WLAN.
- Preferring new messages sent to the WLAN over messages already existing in the WLAN would increase the number of messages currently to be forwarded in the WLAN and thus lead to longer transmission times or congestion and bottlenecks in the transmission of messages.
- the allocation of time slots in relation to the other three radio frequencies F2, F2 and F4 takes place independently of the allocation of the time slots for the first radio frequency F1.
- the other radio frequencies are used for communication between a subscriber radio station and a relay station or a radio access point.
- the base station BS also takes the prioritization of radio stations into account when assigning time slots for the radio frequencies F2, F3 and F4.
- the highest priority is given to the relay stations which have to forward messages directly to a subscriber-side radio station, ie those relay stations which have sent a request message RR-N-MS.
- the second priority is assigned to the radio access points that have to forward messages directly to a subscriber-side radio station, ie to those radio access points that have a request message sent RR-AP-MS. It is also possible that no distinction is made between the radio stations belonging to the request messages RR-N-MS and RR-AP-MS when allocating resources in terms of their priorities, ie that both have the highest priority.
- the lowest priority is assigned to the subscriber radio stations which have sent a request message RR-MS. These are assigned time slots for the radio frequencies F2, F3 and F4 only if, after the assignment of time slots to the relay stations from which the request messages RR-N-MS originate, and to the radio access points from which the request messages RR-AP -MS originate, free time slots are still available.
- each cluster consisting of a relay station and the associated radio stations associated with it, only has time slots for one the radio frequencies F2, F2 and F4 is assigned.
- a frequency band which is divided into a number of OFDM bands, is available for the communication of the subscriber-side radio stations, so the OFDM bands can be divided between the different clusters from which radio resources have been requested.
- the radio stations of the clusters are assigned time slots of their respective cluster frequencies.
- the above statements regarding the prioritization of radio stations when allocating radio resources are particularly useful with regard to radio stations whose signals can interfere undesirably. For example, it is possible to assign the same time slot to the mobile station MS2 and the radio access point AP with respect to the same frequency of the three radio frequencies F2, F2 and F4, since the signals from the mobile station MS2 and the radio access point AP Stand between the mobile station MS2 and the radio access point; AP does not interfere. If the base station BS knows the distances between the radio stations AP, MSI, MS2, N1 and N2 of the WLAN or the network topology of the WLAN, the base station can carry out the prioritization described above in relation to radio stations in which the same radio resource is allocated would cause transmission interference.
- the method described above is carried out in relation to a restricted geographical area. If the distances between the radio stations AP, MSI, MS2, N1 and N2 of the WLAN are not known to the base station BS, however, prioritization can be carried out as described above with respect to all radio stations AP, MSI, MS2, N1 and N2 of the WLAN.
- time slots are primarily assigned to the relay station or the radio access point, followed by the assignment to the subscriber-side radio stations.
- FIG. 3 shows schematically the structure of a base station BS according to the invention.
- An antenna A is used to send and receive messages via the cellular radio interface.
- Request messages received via antenna A reach the means RECEIVE RR, where they are processed and analyzed.
- RECEIVE RR the information taken from the request messages for the allocation according to the method described above is passed on by the RECEIVE RR means.
- the information relevant to the radio stations is passed on to the means TRASNMIT RESSOURCE MESSAGE, which creates a message for the radio stations and emits it via antenna A.
