Description

  The present invention relates to a communication terminal accommodating apparatus and a scheduling method applied to a wired communication system and a mobile communication system, and more particularly to a communication terminal accommodating apparatus and a scheduling method capable of supporting a plurality of networks having different structures.

  In the multimedia interface whose demand has been rapidly increasing in recent years, high-speed and large-capacity data transmission is desired in various user environments such as the public, office, and home. High-speed wireless access networks, high-speed wireless access networks, and the like are attracting attention as one of multimedia interfaces for realizing high-speed and large-capacity data transmission.

  Typical examples of these networks include a master / slave network and a direct connection network. A master / slave network is a network in which a plurality of terminal devices communicate with a communication terminal accommodating device through centralized control by one communication terminal accommodating device. On the other hand, in the direct connection type network, a plurality of terminal devices and other communication terminal accommodating devices communicate with each other by centralized control by the communication terminal accommodating device that has acquired the control right among one or more communication terminal accommodating devices. Is what you do.

  The master / slave network shown in FIG. 14 includes a communication terminal accommodating apparatus 11 having an access point (AP) function corresponding to a base station apparatus in a mobile communication system, and a mobile station apparatus such as a mobile phone. MT terminal devices 12, 13, and 14 having a terminal (MT) function are provided. In the master / slave network, the communication terminal accommodating apparatus 11 executes scheduling for allocating communication resources such as a time domain and a frequency, and always performs communication between MT terminal apparatuses via the communication terminal accommodating apparatus 11.

  The direct connection type network shown in FIG. 15 includes CC / WT terminal devices 21 and 22 having a central controller (CC) function and a wireless terminal (WT) function, and WT terminal devices 23 and 24 having only a WT function, Direct communication between WT terminal devices. At this time, the control right is transferred between the CC / WT terminal devices 21 and 22 having the CC function, and the device having the control right executes scheduling.

  As the range of use of the network expands, there is an increasing demand to use a network that combines a master / slave network and a direct connection network. Therefore, as shown in FIG. 16, a communication terminal accommodating device 31 having a CC / WT / AP function capable of accommodating both an MT terminal device of a master / slave type network and a WT terminal device of a direct connection type network is provided. Consider the network you have.

  Here, in order to perform high-speed and large-capacity data transmission in the multimedia wireless communication system, it is important to perform efficient scheduling for limited communication resources, and various scheduling methods have been proposed so far. Yes. For example, Japanese Patent Laid-Open No. 11-243578 discloses that terminal devices are divided into groups when accommodating terminal devices in order to reduce the management burden of the base station and reduce the buffer size even if the number of terminal devices increases. A method for allocating communication resources in units of groups is described.

  Also in the conventional communication terminal accommodating apparatus 31 in the network shown in FIG. 16, when communication is performed between the WT terminal apparatus and the MT terminal apparatus, scheduling is performed so that communication resource contention and collision do not occur. Hereinafter, the scheduling operation in the conventional communication terminal accommodating apparatus 31 will be described with reference to the timing chart of FIG. 17 taking as an example a case where a communication request is made from the WT terminal apparatus 24 to the MT terminal apparatus 14. Note that FIG. 17 illustrates a case where communication resources are divided in the time domain.

  First, the communication terminal accommodating apparatus 31 performs scheduling for allocating the communication resource Ta-b in the period of time a to b that is not currently used in the direct connection type network, and instructs to transmit data using the communication resource Ta-b. Control information 41 to be transmitted is notified to the WT terminal device 24. Next, the WT terminal device 24 transmits the data 42 using the communication resource Ta-b, and the communication terminal accommodating device 31 receives it.

  Next, the communication terminal accommodating apparatus 31 performs scheduling for allocating the communication resource Tc-d in the period from time c to d which is not currently used in the master / slave network, and receives data by the communication resource Tc-d. Is notified to the MT terminal device 14. Next, the communication terminal accommodating apparatus 31 transmits the data 42 using the communication resource Tc-d, and the MT terminal apparatus 14 receives this.

  In this way, the conventional communication terminal accommodating apparatus performs scheduling for each network so that communication resource contention and collision do not occur, and temporarily receives data transmitted from the transmitting terminal apparatus with a certain communication resource by itself. However, it is transmitted to the receiving side terminal device using other communication resources.

  However, in the conventional scheduling method in the communication terminal accommodating apparatus, when communication is performed between terminal apparatuses accommodated in different networks, communication resources for different periods are allocated for transmission and reception, so high speed, There is a problem that the realization of large-capacity data transmission is hindered. For example, in the case of FIG. 17, the communication resource Ta-b and the communication resource Tc-d for two periods are required to transmit the data 42 from the WT terminal apparatus 24 to the MT terminal apparatus 14.

  The present invention has been made in view of the above points, and provides a communication terminal accommodating apparatus and a scheduling method capable of efficiently using communication resources when communication is performed between terminal apparatuses accommodated in different networks. The purpose is to provide.

  The communication terminal accommodating apparatus of the present invention manages an acquisition means for acquiring information indicating a communication resource allocation status managed by another communication terminal accommodating apparatus of the first network, and a communication resource allocation status of the second network. Both the transmission side and the reception side receive the same communication resource that is currently unused in both of the two networks when communication is performed between the management means that performs and the terminal devices accommodated in either of the two different networks. Communication resource allocating means for allocating to the terminal device.

  The scheduling method of the present invention includes a step of selecting the same communication resource that is currently unused in both of the two networks when performing communication between terminal devices accommodated in either of two different networks; Allocating the same communication resource selected to the transmitting terminal device and the receiving terminal device.

  According to the scheduling method of the present invention, when communication is performed between terminal apparatuses accommodated in one of two different networks, the first communication terminal accommodating apparatus performing scheduling of the first network uses the first network. Assigning communication resources to the first terminal device accommodated in the second terminal device accommodated in the second network at the second communication terminal accommodating device performing scheduling of the second network Allocating the same communication resource as the communication resource allocated to the first terminal device.

  When communication is performed between terminal apparatuses accommodated in different networks, the communication resource allocation unit 205 refers to a table managed in the DL resource management unit 203 and the MS resource management unit 204 and is not used in each network. The same communication resource (for example, T0391-0450) is allocated.

  Next, the scheduling operation of the communication terminal accommodating apparatus 101 will be described with reference to FIGS. 3 and 4 and the timing chart of FIG. 5 in the case where a communication request is made from the WT terminal apparatus 104 to the MT terminal apparatus 106. To do.

  First, a transmission request signal for requesting the MT terminal apparatus 106 to transmit data is transmitted from the WT terminal apparatus 104.

  Hereinafter, the operation of the communication terminal accommodating apparatus 701 when there is a communication request from the WT terminal apparatus 704 to the MT terminal apparatus 706 will be described.

  In this case, first, a transmission request signal requesting the MT terminal apparatus 706 to transmit data is transmitted from the WT terminal apparatus 704. Next, the communication terminal accommodating apparatus 702 that has received the transmission request signal transmits to the communication terminal accommodating apparatus 701 control information for requesting information on communication resources that can be allocated to the master / slave network. This control information is received by the DL interface unit 208 and input to the communication resource allocation unit 801 via the DL control information processing unit 802.

And T1351-2000, the communication terminal accommodating apparatus 702 allocates communication resources for transmission within the range of communication resources T0391-1000 and T1351-2000 that are unused in both networks.

  The communication terminal accommodating apparatus 701 cooperates with the scheduling performed by the communication terminal accommodating apparatus 702. FIG. 9 is a timing chart for explaining a scheduling operation performed by the communication terminal accommodating apparatuses 701 and 702 when there is a communication request from the WT terminal apparatus 704 to the MT terminal apparatus 706.

  The communication terminal accommodating apparatus 702 generates control information 901 instructing data transmission using the allocated communication resource (for example, T0391-0450), and transmits the control information 901 to the WT terminal apparatus 704 and the communication terminal accommodating apparatus 701. In the communication terminal accommodating device 701, the control information 901 is received by the DL interface unit 208 and input to the MS control information generation unit 207 via the DL control information processing unit 802.

  The MS control information generation unit 207 generates control information 902 for instructing data reception using the same communication resource as the transmission communication resource, and transmits the control information 902 to the MT terminal device 706 via the MS interface unit 209.

  Then, the WT terminal apparatus 704 transmits data 903 using the communication resource indicated by the control information, and the transmitted data 903 is transmitted to the MT via the DL interface unit 208 and the MS interface unit 209 of the communication terminal accommodating apparatus 701. It is received by the terminal device 706.

  It should be noted that the transmission interval between the control information 901 and the control information 902 only needs to be separated within the specified range of the network to be accommodated, other communication may be established at equal intervals, and further continuous. May be. Further, communication such as bandwidth request and communication control may be performed before and after the information communication, but it is only necessary to comply with the communication protocol of each network.

  Next, the operation of communication terminal accommodating apparatus 701 when there is a communication request from MT terminal apparatus 706 to WT terminal apparatus 704 will be described.

  In this case, the MT transmission request processing unit 202 processes the transmission request signal transmitted from the MT terminal device 706 and outputs it to the communication resource allocation unit 801.

  The communication resource allocation unit 801 refers to the table managed by the MS resource management unit 204 and outputs communication resources suitable for communication to the DL control information processing unit 802. The DL control information processing unit 802 generates information indicating communication resources suitable for communication in the master / slave network, and transmits the information to the communication terminal accommodating device 702 via the DL interface unit 208.

  The communication terminal accommodating apparatus 702 refers to the information received from the DL control information processing unit 802 and the current communication resource allocation status of the direct connection type network, and performs scheduling for allocating reception communication resources.

  The communication terminal accommodating apparatus 701 cooperates with the scheduling performed by the communication terminal accommodating apparatus 702. FIG. 10 is a timing diagram for explaining a scheduling operation performed by the communication terminal accommodating apparatuses 701 and 702 when there is a communication request from the MT terminal apparatus 706 to the WT terminal apparatus 704.

  The communication terminal accommodating apparatus 702 generates control information 1001 instructing data reception with the allocated communication resource (for example, T0391-0450), and transmits the control information 1001 to the WT terminal apparatus 704 and the communication terminal accommodating apparatus 701. In communication terminal accommodating apparatus 701, control information 1001 is received by DL interface unit 208 and input to MS control information generation unit 207 via DL control information processing unit 802.

  The MS control information generation unit 207 generates control information 1002 instructing data transmission using the same communication resource as the reception communication resource, and transmits the control information 1002 to the MT terminal apparatus 706 via the MS interface unit 209.

  Then, the MT terminal device 706 transmits the data 1003 using the communication resource indicated by the control information, and the transmitted data 1003 is transmitted to the WT via the MS interface unit 209 and the DL interface unit 208 of the communication terminal accommodating device 701. It is received by the terminal device 704. Since the MT terminal device 706 is a terminal device in the master / slave network, it transmits data to the communication terminal accommodating device 701. However, the communication terminal accommodating device 701 does not operate on the received data. Therefore, communication from the MT terminal device to the WT terminal device can be established after all.

  It should be noted that the transmission interval between the control information 1001 and the control information 1002 only needs to be separated within a specified range of the accommodated network, other communications may be established at equal intervals, and further, they are continuous. May be. Further, communication such as bandwidth request and communication control may be performed before and after the information communication, but it is only necessary to comply with the communication protocol of each network.

  As described above, according to the second embodiment, when communication is performed between terminal apparatuses accommodated in different networks, the communication terminal accommodating apparatus having the AP function performs scheduling in cooperation with the communication terminal accommodating apparatus having the CC function. By doing so, one communication resource can be allocated to one data communication, and the communication resource can be used efficiently.

(Embodiment 3)
Here, there are a plurality of types of wireless network standards, and some of them can be merged as in the first and second embodiments. For example, although the network configurations of HiSWAN and HiperLAN are different from each other, the arrangement of channels is almost the same, so that communication can be performed with the same communication resource between terminal devices accommodated in different networks. The network configuration of HiSWAN is generally a master / slave type, and the network configuration of HiperLAN is a master / slave type or a direct connection type.

  On the other hand, some wireless network standards cannot be easily integrated using the present invention. For example, IEEE802.11 and HiperLAN have completely different channel arrangements, so that terminal devices accommodated in networks of different standards cannot communicate with each other with the same communication resource. In such a case, a plurality of communication frames are prepared as shown in FIG. 11 (FIG. 11 shows a case where two communication frames 1101 and 1102 are prepared), and information on standards that cannot be merged with each other in each communication frame. In a time zone in which information is transmitted in a certain communication frame, scheduling is performed so that information is not transmitted in other communication frames. FIG. 11 shows a case in which IEEE802.11 information is transmitted in the communication frame 1101, HiperLAN or HiSWAN information is transmitted in the communication frame 1102, and the communication frame for transmitting the information is scheduled to be switched every 2 ms.

  A plurality of communication frames prepared for transmitting information between standards that cannot be merged with each other is referred to as “multiframe”. In Embodiment 3, a communication terminal accommodating apparatus and a scheduling method in a multiframe network will be described.

  FIG. 12 is a block diagram showing a configuration of a network including a communication terminal accommodating apparatus according to Embodiment 3 of the present invention. In FIG. 12, a first network 1201 is a network obtained by merging a master / slave network and a direct connection network as shown in the first embodiment. The second network 1202 is a standard network that cannot be merged with the first network 1201. For example, the first network 1201 is a network that combines HiperLAN and HiSWAN, and the second network 1202 is an IEEE802.11 network. The multiframe scheduler 1203 allocates communication resources between the first network 1201 and the second network 1202.

  Compared with the network shown in FIG. 1, first network 1201 is different from communication terminal accommodating apparatus 101 only in the internal configuration of communication terminal accommodating apparatus 1211 according to the present embodiment. FIG. 13 is a block diagram showing the configuration of the communication terminal accommodating apparatus 1211. In the communication terminal accommodating device 1211 shown in FIG. 13, the same components as those in the communication terminal accommodating device 101 shown in FIG.

  The communication terminal accommodating apparatus 1211 shown in FIG. 13 differs from the communication resource allocating unit 205 in the operation of the communication resource allocating unit 1301 with respect to the communication terminal accommodating apparatus 101 shown in FIG. 13 adopts a configuration in which an MF (multi-frame) control information processing unit 1302 and an MF interface unit 1303 are added to the communication terminal accommodating device 101 shown in FIG.

  The MF control information processing unit 1302 receives information indicating the communication resource allocated to the first network 1201 by the multiframe scheduler 1203 via the MF interface unit 1303 and outputs the information to the communication resource allocation unit 1301.

  The communication resource allocation unit 1301 refers to the information input from the MF control information processing unit 1302 and performs scheduling within the range of communication resources allocated to the first network 1201.

  For example, when there is a communication request between terminal apparatuses accommodated in different networks of the first network 1201, the communication resource allocation unit 1301 performs the DL resource management unit 203 and the MS resource management unit as in the first embodiment. Referring to the table managed by 204, scheduling is performed to allocate communication resources suitable for communication within the range of communication resources allocated to the first network 1201.

  Further, when there is a communication request from the terminal device accommodated in the first network 1201 to the terminal device accommodated in the second network 1202, it is currently not within the range of communication resources allocated to the first network 1201. Scheduling to allocate the used communication resource as a communication resource for transmission is performed, and the MF control information processing unit 1302 is notified. In response to the notification from the communication resource allocation unit 1302, the MF control information processing unit 1302 generates control information for scheduling, and transmits the control information to the multiframe scheduler 1203 via the MF interface unit 1303.

  Thus, by performing scheduling within the range of communication resources allocated by the multiframe scheduler, the present invention can be applied to a multiframe network configuration.

  Note that even standards such as HiperLAN and IEEE802.11 that cannot be easily merged at the time of the present invention will be expanded in the future according to the arrangement of channels due to message extension and extension for interconnection. It is conceivable that the failure can be reduced and communication can be performed with the same communication resource in part or all of the communication period. In this case, the method shown in the present invention can be applied in communication between these standards.
