Description

Method for allocating radio resources for WLAN {METHOD FOR ALLOCATING RADIO RESOURCES FOR A WLAN}

The present invention relates to a method for allocating radio resources to wireless stations in a wireless communication system in which messages are transmitted between wireless stations by being forwarded through other wireless stations. In addition, the invention relates to a wireless device for implementing the method.

In a wireless communication system, messages such as voice messages, messages with image information, video information, Short Message Service (SMS), Multimedia Messaging Service (MMS) or other data are transmitted over the air interface with the aid of electromagnetic waves. And between the receiving station. In this regard, depending on the particular embodiment of the wireless communication system, the wireless stations may be various types of wireless stations on the subscriber side or wireless stations on the network side, such as wireless access points, repeaters or base stations. In a mobile wireless communications system, at least some of the wireless stations on the subscriber side are mobile wireless stations. Radiation of electromagnetic waves is carried out using carrier frequencies located in the frequency band provided for each system.

Mobile wireless communication systems, for example, have a network infrastructure consisting of base stations, devices for control and management of base stations, and additional devices on the network side, such as Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications (UMTS). System) is often designed as cellular systems according to the standard.

In addition to these cellular, hierarchical wireless networks that are organized for long-term (transnational) use, there are also Wireless Local Area Networks (WLANs), which generally have a much more limited range of wireless coverage. With a diameter of up to several hundred meters, the cells covered by wireless access points (APs) for WLANs are smaller than normal mobile wireless cells. Examples of different standards for WLANs are HiperLAN, DECT, IEEE 802.11, Bluetooth and WATM.

An unlicensed frequency range of about 2.4 GHz is generally used for WLANs. Data rates up to 11 Mbit / s. Future WLANs can operate in the 5 GHz range and can achieve data rates higher than 50 Mbits / s. Thus, much higher data rates are possible for subscribers of WLANs than are provided by third generation mobile radio. For this reason, access to WLANs for high-bit rate connections is useful for the transmission of large amounts of data, especially with regard to Internet access.

Therefore, connection to other communication systems, such as the Internet, may occur via WLAN wireless access points. To this end, the radio stations for the WLAN at the subscriber side communicate directly with the radio access point, or for other stations further away, via other radio stations that forward messages between the subscriber side radio station and the wireless access point. In general, scarce available radio resources are partitioned among wireless stations in the WLAN. If splitting occurs in such a way that a large number of radio resources are available to the first station forwarding messages, while very few radio resources are available to the second station forwarding messages, consequently congestion in the transmission of messages, Overloading of the second forwarding radio station, and finally loss of messages may occur.

It is an object of the present invention to provide an efficient method for allocating radio resources to radio stations in a wireless communication system in which message transmissions between radio stations are made by forwarding messages through other radio stations. In addition, a wireless device for the allocation of radio resources should be introduced for the implementation of the method.

The object is achieved by a method having the features of claim 1 and a wireless device having the features of claim 10.

Useful embodiments and refinements are the subject matter of the dependent claims.

The method according to the invention allocates radio resources to radio stations of a wireless communication system. In a wireless communication system, message transmissions between wireless stations are made by forwarding the messages through other wireless stations. There are different classes of stations whose respective functions are available while the messages are being sent. The wireless device receives request messages from the radio stations to request the allocation of radio resources necessary for the transmission or forwarding of the messages. According to the present invention, a wireless device allocates radio resources to radio stations that have requested allocation of radio resources in consideration of the classes of the radio stations. In addition, the wireless device provides notification of the assignment using one or more messages.

Messages can only be transmitted over the air between radio stations, which means that the infrastructure for transmitting over wires is not included. For example, wireless stations in a wireless communication system may involve wireless stations in a WLAN, for example in the form of wireless stations, relay stations and wireless access points on the subscriber side. The wireless device may, for example, involve a base station of a cellular wireless communication system. Each radio station of the wireless communication system participating in the transmission of messages belongs to one or more classes. In this regard, the classes relate to the function of the radio station while the messages are being sent. Equally-equipped wireless stations may belong to different classes. If a radio station belongs to multiple classes, the wireless device can identify from which class of radio station the query was generated from a request message from the radio station for radio resources. The membership status of a station in one or more classes may change over time.

For example, the radio resources that the wireless device allocates to the radio stations may be one or more radio frequencies, such as, for example, OFDM bands, and / or time slots and / or codes and / or directions in space. Allocation of a combination of time slots and radio frequencies is particularly useful. Allocation of radio resources by the wireless device occurs taking into account the ratings of the radio stations. For example, such allocation may be realized by prioritization of different classes and the allocation of radio resources based on the order for the prioritization. Thus, for example, it is possible to allocate radio resources to lower priority radio stations only if higher priority radio stations are not used and thus the requested radio resources are not allocated. Consideration of prioritization may be limited to some radio resources; Thus, for example, different priority settings may occur for each of the radio resources and may also be limited to some radio stations; Thus, for example, consideration of setting some priorities may only occur for stations in some geographical range. After the assignment is made, the wireless device provides notification of the assignment. The dispatch of a message with information about an assignment may only be sent from the wireless device to all stations, or to those stations that have been assigned radio resources and / or subsequently to those stations forwarding the information about the assignment to other stations. Can be.

In an embodiment of the present invention, stations of the first class of wireless stations forward the messages received from the wireless stations to other wireless stations in order for the messages to be forwarded. In this regard, for example, repeaters or relay stations may be involved which do not introduce any new messages into the wireless communication system but instead forward messages introduced into the wireless communication system by other wireless stations. Radio stations of the first class may in particular involve radio stations on the network side.

In an embodiment of the present invention, the second class of wireless stations forward messages received from the wireless stations to the wireless stations to which the respective messages are addressed. In this regard, for example, repeaters or relay stations may be involved which do not introduce any new messages into the wireless communication system but instead forward messages introduced into the wireless communication system by other wireless stations. Class 2 radio stations may in particular involve radio stations on the network side.

The radio station may belong to the first and second class of radio stations; The station's class membership status for a particular message depends on which station the received and forwarded message is intended for.

In an embodiment of the present invention, the third class of wireless stations forward messages received from other communication systems to the wireless stations for the messages to forward. Class 3 wireless stations may involve wireless access points, for example, for a WLAN having a connection to the Internet. Other communication systems can be designed as wireless communication systems. Class 3 radio stations may in particular consist of radio stations on the network side.

In an embodiment of the present invention, wireless stations of the fourth class among the wireless stations forward messages received from other communication systems to the wireless station to which each message is addressed. Class 4 wireless stations may, for example, involve wireless access points for a WLAN having a connection to the Internet. Other communication systems can be designed as wireless communication systems. The fourth class radio stations may in particular consist of radio stations on the network side.

The radio station may belong to third and fourth class radio stations; The rank membership of a station for a particular message depends on which station the message received and forwarded from another communication system is intended.

In an embodiment according to the invention, radio stations of the fifth class among the radio stations transmit their messages to the radio stations. The messages have not been received from another radio station for forwarding, but instead carry a newly transmitted message to the wireless communication system by the radio station. Class 5 radio stations may in particular be subscriber stations.

The ranks while radio resources are allocated in such a way that time slots are sequentially assigned to radio frequencies in accordance with prioritization settings for the stations, i.e. assigned to stations of the first class and then to stations of the third class. It is useful to have consideration of these fields happen. In this case, all or at least some of the first and third classes of radio stations use the same radio frequency. Radio stations of the first class are preferentially handled in the allocation of radio resources, and radio stations of the first class are those that forward messages that already exist in the wireless communication system. In contrast, the lower class radio station of the third class sends new messages to the wireless communication system. Thus, the newly transmitted messages in the wireless communication system are placed after the messages already present in the wireless communication system.

According to a useful refinement of the invention, consideration of ratings while radio resources are allocated is based on the manner in which time slots are sequentially assigned to one or more radio frequencies in accordance with prioritization for radio stations, ie first and second. It occurs in a manner that is assigned to the fourth grade and then assigned to the fifth grade. In this case the second and fourth classes, i.e. the two classes where the radio stations forward messages to the destinations of the messages together, receive a higher priority. Differentiation between the priorities of the two classes is also possible. New dispatches of messages to wireless communication systems in turn have lower priorities. A combination of the second, fourth and fifth priority settings described herein and the priority of the first and third grades described above is also possible. Advantageously, the radio frequencies or frequencies divided between the stations of the second, fourth and fifth classes involve radio frequencies which are not those divided between the stations of the first and third classes.

According to an embodiment of the invention, wireless stations in a wireless communication system communicate with each other using a first air interface and with a wireless device using a second air interface. For example, the first wireless interface may involve a wireless interface of a WLAN and the second wireless interface may involve a cellular wireless interface.

A wireless apparatus in accordance with the present invention for allocating radio resources to wireless stations of a wireless communication system comprises: means for receiving and processing request messages for requesting allocation of radio resources to send or forward messages from wireless stations; Means for allocating radio resources to the radio stations that have requested allocation of radio resources in view of the ratings of the stations, and means for generating and transmitting one or more messages with information regarding the allocation of radio resources.

The wireless device according to the invention is particularly suitable for the implementation of the method according to the invention, whereby the wireless device also applies to embodiments and improvements. For this purpose, the wireless device may further comprise suitable means. It is possible to implement a wireless device according to the invention using a plurality of devices associated with one another, each with its own means.

The invention is explained in more detail below on the basis of an exemplary embodiment.

1 is a diagram of a wireless communication system,

2 is a schematic diagram of the contents of a message transmitted according to the method of the present invention, and

3 is a schematic diagram of a design of a base station according to the present invention;

A WLAN consisting of a wireless access point (AP), two mobile stations MS1, MS2, and two relay stations N1, N2 is shown in FIG. The wireless access point (AP) has a connection to the Internet (INTERNET). The relay stations N1 and N2 are fixed radio stations on the network side that forward messages between the mobile stations MS1 and MS2 and the wireless access point AP. Additionally or alternatively, all or part of the message forwarding may be performed by fixed or mobile radio stations on the subscriber side. The WLAN may include relay stations, as well as additional wireless access points—not shown in FIG. 1 for simplicity — at the subscriber side.

The transmission of messages between wireless stations AP, MS1, MS2, N1, N2 of the WLAN takes place using the WLAN wireless interface. As with the mobile station MS1 of Fig. 1, when the subscriber station's radio station is located within the radio range of the radio access point AP, the subscriber station radio station can communicate directly with the radio access point AP. For mobile stations on the subscriber side further away, such as mobile station MS2 of FIG. 1, the transmission of messages between the wireless access point AP and the subscriber station radio station is accomplished by forwarding the messages through relay stations. Therefore, the message from the wireless access point AP to the mobile station MS2 is transmitted by the wireless access point AP to the relay station N1, and the relay station N1 forwards the message to the relay station N2, The relay station N2 forwards the message to the mobile station MS2.

The first radio frequency is available in the WLAN for communication between the relay stations N1 and N2 and the wireless access point AP as well as between the relay stations N1 and N2.

In addition, three other radio frequencies are available for communication between the radio access point AP and the mobile stations MS1, MS2 as well as between the relay stations N1 or N2 and the mobile stations MS1 or MS2. Thus, three additional radio frequencies are always used when the subscriber station's radio station is participating in communication.

The wireless stations AP, MS1, MS2, N1, N2 of the WLAN are located in a radio cell (shown in clouds) of a base station BS of a cellular wireless communication system, such as a system according to the UMTS standard. Additional components of the cellular wireless communication system are not shown for simplicity. The wireless access point (AP), relay stations (N1, N2), and mobile stations (MS1, MS2) may optionally communicate with the base station (BS) using a cellular air interface. Since lower radio frequencies are used for communication using a cellular air interface rather than communication within a WLAN, the wireless access point (AP), relay stations (N1, N2), and mobile stations (MS1, MS2) may optionally It can communicate directly with the base station BS without forwarding. If the equipment does not allow the subscriber station to communicate with the base station (BS) using the cellular air interface, the communication between each radio station on the subscriber side and the base station (BS) is currently located in the vicinity of the subscriber station. It can be done through the relay station. Thus, mobile station MS2 may be able to communicate with base station BS via relay station N2 if it is unable to communicate using the cellular air interface.

If the mobile station MS1 or MS2 wishes to send a message, the mobile station MS1 or MS2 requires radio resources for this. The message to be transmitted by the mobile station MS1 or MS2 may be, for example, a data request message to the Internet INTERNET. The mobile station MS1 or MS2 sends a request message (RR-MS) (RR: Resource Request) for allocation of radio resources. The request message RR-MS is transmitted by the mobile station MS2 directly to the base station BS or by the relay station N2 or by the mobile station MS1 to the wireless access point AP so as to transmit the radio. An access point (AP) may forward the message to the base station (BS). For dispatch of a request message (RR-MS) to a relay station or a wireless access point, the subscriber station's radio station uses one of three radio frequencies that can be used for communication by the subscriber station's radio stations.

When the relay station N2 receives a message from the mobile station MS2 to be forwarded to the wireless access point AP through the relay station N1, the relay station N2 transmits a request message RR-NN to the base station BS. Thereby, the base station BS is requested to allocate radio resources to relay station N2 for transmission of a message to another relay station. By doing so, the request message RR-N-N may include identification information for relay station N1. However, the base station BS can also infer from the request message RR-N-N that radio resources will be required by the relay station N2 for transmission of the message to the other relay station.

When relay station N2 receives a message to be forwarded from relay station N1 to mobile station MS2, relay station N2 sends a request message RR-N-MS to base station BS. The base station BS recognizes from the request message RR-N-MS that the relay station N2 requests radio resources for forwarding the message to the radio station on the subscriber side. The request message RR-N-MS may include identification information for mobile station MS2.

In addition, when the relay station N1 needs to forward a message from the wireless access point AP to the relay station N2 or from the relay station N2 to the wireless access point AP, the relay station N1 sends a request message RR-NN to the base station. Send similarly to (BS). If no identifying information about the radio stations to which the message should be forwarded is included in the request messages RR-NN received from the relay stations N1 and N2, the message is forwarded to the relay station N1 or N2 or wirelessly. It is not possible to infer from the request messages whether or not it is forwarded to an access point (AP). This is because the same radio frequency is used for communication between relay stations N1 and N2 and between relay station N1 and the wireless access point AP.

When a message received at the mobile station MS1 from the Internet INTERNET is available to the wireless access point AP, the wireless access point AP sends a request message RR-AP-MS. The base station BS infers from the request message RR-AP-MS that the message is sent directly from the wireless access point (AP) to the subscriber station's radio station and that resources are required for the transmission. Identification information for the mobile station MS1 may be included in the request message RR-AP-MS. In contrast, when the destination of the message received from the Internet (INTERNET) by the wireless access point (AP) is the mobile station MS2, the transmission of the message to the relay station at the same time, optionally referring to the identification information for the relay station N1. A request message (RR-AP-N) having contents for requesting radio resources for the radio access point (AP) is transmitted to the base station (BS).

Each of the described request messages (RR-MS, RR-NN, RR-N-MS, RR-AP-MS, RR-AP-N) contains information about the message or range of messages to be transmitted in each case. As a result, the base station BS can infer from the request messages what range of radio resources are allocated to each radio station.

Thus, there are request messages (RR-MS, RR-N-N, RR-N-MS, RR-AP-MS, RR-AP-N). The differences between the request messages are due to the functions of the wireless stations AP, MS1, MS2, N1, N2 of the WLAN while the messages are being sent. This means that different classes of radio stations are available for the functions of the radio stations AP, MS1, MS2, N1, N2 of the WLAN while the messages are being transmitted. The request messages (RR-MS) come from radio stations on the subscriber side that do not forward any messages but instead send new messages. The request messages RR-N-N come from relay stations which forward messages to other relay stations from other relay stations or from the subscriber's radio station or from a wireless access point. The request messages RR-N-MS come from relay stations which forward a message received from another relay station or from a wireless access point to the radio station of the subscriber side addressed in the message. The request messages (RR-AP-MS) come from a wireless access point which forwards the message received from another communication system for the radio station on the subscriber side directly to the radio station on the subscriber side. The request messages RR-AP-N come from a wireless access point which forwards the message received from another communication system to the relay station for forwarding the message.

Upon receiving the request messages, the base station BS allocates radio resources to the wireless stations AP, MS1, MS2, N1, N2 of the WLAN at regular time intervals. When determining which radio resources are to be assigned to which radio station, the base station BS considers the ratings of the above-mentioned radio stations from which they have received respective request messages. After deciding on the assignment, the base station (BS) sends a message to the corresponding stations to inform about the assignment.

2 shows the design of such an information message (RESOURCE MESSAGE) transmitted by a base station (BS). The first part (PREAMBLE) of the message RESOURCE MESSAGE indicates that the time interval starts a new radio resource allocation. The following parts tell the radio stations which radio resources are allocated to the radio stations. The base station (BS) transmits a message (RESOURCE MESSAGE) to all relay stations and radio access points to which radio resources are allocated. To this end, a message (RESOURCE MESSAGE) may be broadcast by the base station (BS) for each broadcast. Radio stations on the subscriber side to which radio resources have been allocated receive information (RESOURCE MESSAGE) directly from a base station (BS) or information or message regarding radio resources allocated to the radio stations by a relay station or a wireless access point (RESOURCE MESSAGE). Receive a message (RESOURCE MESSAGE) by receiving.

The first radio frequency F1 is used by the relay stations N1 and N2 and the radio access point AP, which means transmissions or forwardings for all messages in a WLAN that do not involve any radio station on the subscriber side. do. Therefore, for the first radio frequency F1, the base station BS assigns time slots to the radio stations N1, N2, AP. The assignment occurs depending on the received request messages and the class of the radio station that requested the radio resources. The relay stations that have sent the request message RR-N-N have the highest priority in the allocation of time slots for the first radio frequency F1. The access points that sent the request message (RR-AP-N) follow. The allocation of time slots for the first radio frequency F1 at the radio access points therefore only takes place if the requested radio resources are assigned to each relay station which has requested allocation of radio resources within the required range. The reason for this solution is that the messages forwarded by the relay stations are already coming from other relay stations in the WLAN and are therefore quickly sent to the addressed radio station, since unnecessary delays due to long stopovers at the relay station Means none. However, messages that the wireless access point transmits using the resources allocated for the request message RR-AP-N arrive at the WLAN newly from the wireless access point (AP). Prioritizing newly transmitted messages to the WLAN over messages already present in the WLAN may increase the number of messages forwarded simultaneously in the WLAN, thus resulting in longer transmission times or congestion and bottlenecks in the transmission of messages. Induce phenomena.

The assignment of time slots for the other three radio frequencies F2, F3, F4 is made independent of the assignment of time slots for the first radio frequency F1. Additional radio frequencies are used for communication between the subscriber station radio station and the relay station or radio access point. Even while time slots for radio frequencies F2, F3, F4 are allocated, the base station BS considers prioritization for radio stations. While resources are allocated, the highest priority is given to the relay station (the relay station that sent the request message (RR-N-MS)) that has been asked to forward the messages directly to the subscriber station's radio station. The second priority is assigned to the wireless access points (the wireless access point that sent the request message RR-AP-MS) requested to forward the messages directly to the subscriber station's wireless station. In addition, the radio stations related to the request messages (RR-N-MS, RR-AP-MS) may not be distinguished about their priorities during resource allocation, which means that both receive the highest priority. The lowest priority will be assigned to the stations on the subscriber side that sent the request message (RR-MS). The time slots for radio frequencies F2, F3, F4 are then relayed to which the request messages RR-N-MS are transmitted and to which radio the request messages RR-AP-MS are transmitted. After time slots have been assigned to access points, they are assigned to the radio frequencies only if free time slots are available.

While time slots are allocated for the additional three radio frequencies F2, F3, F4, each cluster of relay stations and their associated stations on the subscriber side is for one of the radio frequencies F2, F3, F4. It is useful for the above-described priority setting to take place using a constraint assigned to time slots. If a frequency band is available to wireless stations on the subscriber side, for example, for communication divided into multiple OFDM bands, the OFDM bands may be divided between different clusters for which radio resources have been requested. As described above for each cluster frequency, time slots are allocated to radio stations in the cluster.

The above embodiments regarding prioritization of radio stations while radio resources are allocated are particularly sensitive to each radio station whose signals may interfere in an undesired manner. Thus, for example, it is possible to assign the same time slots to the mobile station MS2 and the radio access point AP for the same frequency of the three radio frequencies F2, F3, F4, because from the mobile station MS2 And because signals from the wireless access point AP do not interfere due to the distance between the mobile station MS2 and the wireless access point AP. If the distances between the wireless stations AP, MS1, MS2, N1, N2 in the WLAN or WLAN's network topology are known to the base station BS, then the base station may cause transmission disruptions due to the same allocation of radio resources. With respect to those stations, the priority setting described above may be taken in each case. The method described above is carried out in this case with regard to the limited local area. In contrast, if the wireless stations AP, MS1, MS2, N1, N2 of the WLAN are unknown to the base station BS, the priority setting is with respect to all the wireless stations AP, MS1, MS2, N1, N2 of the WLAN. It may be performed as described above.

If the OFDM bands are divided between clusters, the same OFDM bands can be allocated to clusters that are sufficiently far apart. Within any cluster, time slots are preferentially assigned to a relay station or a wireless access point and then to radio stations on the subscriber side.

3 shows a schematic diagram of a design of a base station (BS) according to the invention. Antenna A provides for the transmission and reception of messages over a cellular air interface. The request messages received via the antenna A arrive at the means (RECEIVE RR), where the request messages are processed and analyzed. In order to determine the allocation of radio resources in the DETERMINE ALLOCATION, the information deduced from the request messages relating to the allocation according to the method described above is forwarded from the RECEIVE RR. After the determination regarding the assignment, the information related to the radio stations is forwarded to the means (TRANSMIT RESOURCE MESSAGE), and the means (TRANSMIT RESOURCE MESSAGE) generates a message for the stations and broadcasts the generated message through the antenna (A). do.
