  The present invention relates to a PHS (Personal Handy-phone System) wireless communication system, a wireless communication control device, a wireless slave, a PHS wireless communication method, a PHS wireless communication program, and a program recording medium, and more particularly in a wireless communication system such as a PHS system. , PHS wireless communication system, wireless communication control device, wireless slave unit, PHS wireless communication method, PHS wireless communication program, and program recording capable of minimizing delay of call timing of wireless slave unit (PS) It relates to the medium.

  In a PHS wireless communication system using a PHS (Personal Handy-phone System) system, as shown in FIG. 8, an incoming call (individual incoming call) to a destination wireless slave station (PS) is a button telephone in a local network. From a wireless communication control device (main device) such as a device, a PBX (Private Branch Exchange) system, or a telephone exchange device in a public network, to each subordinate base station (CS: Cell Station), for example, base stations CS1, CS2, CS3 An incoming call is notified to a destination wireless station (PS: Personal Station), for example, the wireless station PS1. FIG. 8 is a sequence diagram for explaining an incoming call operation in a PHS radio communication system using the PHS system, and is connected to a radio communication control apparatus that is a main apparatus of the PHS radio communication system and the radio communication control apparatus. The flow of signals transmitted and received between each base station CS1, CS2, CS3 and the destination wireless slave device PS1 is shown.

  In FIG. 8, the destination radio handset PS1 is in a state of waiting for a signal from the base station CS3 so as to monitor the incoming message channel PCH1 from the base station CS3 for incoming notification in the standby state. It is assumed that it is set.

  In FIG. 8, the radio communication control apparatus, which is the main apparatus of the PHS radio communication system, notifies each base station CS1, CS2, CS3 connected to the subordinate of the incoming call to the radio slave unit PS1. (Sequence Seq1, Seq2, Seq3), each base station CS1, CS2, CS3 has a plurality of incoming call message channels (PCH: Paging Channel) for notification of incoming calls allocated in the control channel (CCH: Control Channel). Among them, an incoming call message channel (PCH) corresponding to an incoming call group of the destination wireless slave unit PS1, for example, an incoming message channel PCH1 of the first group is used to transmit an incoming call to the wireless slave unit PS1 (sequence). Seq4, Seq5, Seq6).

  The destination wireless slave unit PS1 is set to a standby state among the incoming call message channels PCH1 for notification of incoming calls to the first group of wireless slave units (PS) transmitted from the base stations CS1, CS2, and CS3. By receiving the incoming call message channel PCH1 from the base station CS3 being detected and detecting that the incoming call message channel PCH1 includes a PS number indicating the wireless slave unit (PS), Receiving notification of incoming call to handset PS1 and starting incoming call processing (sequence Seq7).

  If it is determined by the activated incoming call processing that the incoming call can be accepted, a link channel (LCH: Link Channel) allocation request signal is returned to the base station CS3 from the destination wireless slave unit PS1 ( Sequence Seq8). Receiving the link channel assignment request signal, the base station CS3 returns a link channel assignment signal including information on a traffic channel (TCH: Traffic Channel) for communication (sequence Seq9). Through the sequence as described above, the destination wireless slave unit PS1 enters a state in which a call is made with the communication partner that has made a call using the allocated traffic channel (TCH) for the call via the base station CS3. Transition (sequence Seq10).

  By the sequence as described above, an incoming call operation for the wireless slave device PS1 is performed using an incoming message channel (PCH) corresponding to the incoming call group of the wireless slave device PS1, for example, the incoming message channel PCH1.

  Here, when an incoming call is received from the base station (CS) to the wireless slave unit (PS), as shown in FIG. 9, the PS indicating the destination wireless slave unit (PS) in the incoming call message channel (PCH). Sent with a number. FIG. 9 is an explanatory diagram for explaining the message format of the incoming call message channel (PCH) in the PHS wireless communication system, established by the RCR STD-28 standard (Research & Development Center for Radio Systems (RCR)). Incoming call message channel that is compliant with the 2nd generation cordless telephone system's domestic standard for wireless interface and is transmitted in the downlink direction from the base station (CS) to the wireless slave unit (PS) for incoming call notification. The message format of (PCH) is shown. As shown in FIG. 9, the incoming call message channel (PCH) is composed of 8 octets, and the PS number (1st digit) of the 4th to 1st bits after the 1st octet and the 7th octet PS. Up to the number (12th number) and PS number (13th number), the PS number indicating the destination wireless slave device (PS) is included together with the first octet calling service type (service type indicating incoming call notification). ing.

  The wireless handset PS1 that has received the incoming call message channel PCH1 has a PS number (first number) to PS number (13th number) included in the incoming call message channel PCH1 that indicates the own wireless handset PS1. By recognizing that it is a number, it is detected that there has been an incoming call addressed to its own wireless handset PS1.

  In addition, as defined in the RCR STD-28 standard, the incoming call group is a group of a plurality of wireless slave units (PS) as a unit that enables simultaneous incoming calls through the incoming call message channel (PCH). The group is configured by a numerical value obtained by adding “1” to the remainder when the PS number indicating the wireless slave unit (PS) is divided by the number of incoming call groups. For example, when the number of incoming call groups is “4” and the wireless slave unit (PS) has a PS number of “200”, the incoming group (group) of the wireless slave unit (PS) is “1” (= 200 (MOD4) +1).

  Also, the downlink control signal from the base station (CS) to the wireless slave unit (PS) is transmitted as a logical control channel (LCCH) superframe as shown in FIG. Has been. FIG. 10 is an explanatory diagram showing a frame structure of a logical control channel (LCCH) superframe for transmitting a downlink control signal in the PHS wireless communication system. The logical control channel (LCCH) superframe is a broadcast channel ( It consists of BCCH (Broadcasting Control Channel), a plurality of incoming message channels (PCH) corresponding to the number of incoming call groups, and a plurality of signaling control channels (SSCH) for dedicated cells.

  FIG. 10 shows an example in which the number of incoming call groups of the plurality of incoming message channels (PCH) included in the logical control channel (LCCH) superframe is “4”. The case where the number of incoming call message channels PCH4 consists of four channels is shown. The incoming message channel PCH1 to incoming message channel PCH4 are transmitted as a general calling channel at a timing synchronized with the reception timing of the wireless slave unit (PS) of each incoming call group. During battery saving, the device (PS) receives and synchronizes the reception timing of the incoming call message channel (PCH) for the wireless slave device (PS) with the incoming message channel for the wireless slave device (PS). (PCH) is received.

  That is, as shown in FIG. 10, the wireless slave unit PS1 with a PS number of “200” and the wireless slave unit PS5 with a PS number of “204” are both in the standby state where the incoming call group is “1”. In the standby state, each of the wireless slave units PS1 and PS5 belonging to the incoming call group 1 turns on the reception gate Rx at the transmission timing of the incoming message channel PCH1, and At other timings, the receiving gate Rx is turned off. In addition, the wireless slave device PS3 with the PS number “202” belongs to the incoming call group 3 whose incoming call group is “3”, and the wireless slave device PS3 belonging to the incoming call group 3 receives an incoming call in a standby state. At the transmission timing of the message channel PCH3, the reception gate Rx is turned on, and at other timings, the reception gate Rx is turned off.

  As described above, in the current PHS wireless communication system compliant with the RCR STD-28 standard, a plurality of wireless slaves (PS: Personal) are connected to the same incoming call message channel (PCH: Paging Channel) as the same incoming call group. Station, mobile station, mobile terminal).

  As a result, when there is an individual incoming call to a plurality of wireless slave units (PS) belonging to the same incoming call group at the same time, in order to call the first wireless slave unit (PS), During an incoming call to the second wireless slave unit (PS), the corresponding incoming call message channel (PCH) in the CCH (Control Channel) is used to call only one of the first wireless slave units. Therefore, it will be occupied. That is, even if there is an incoming call to another wireless slave device (PS) belonging to the same incoming call group, the incoming call to the first wireless slave device (PS) that has been called first is terminated, etc. Until the incoming call message channel (PCH) is released, the incoming call to the subsequent wireless slave unit (PS) is waited (that is, the incoming call is not notified to the subsequent wireless slave unit (PS)). There was a problem of becoming.

  Furthermore, if there is an individual incoming call to a plurality of wireless slave units (PS) belonging to the same incoming call group at the same time, transmission is made to the first wireless slave unit (PS). There is a problem that the incoming calls of the second and subsequent wireless slave units (PS) are delayed because the incoming call message channel (PCH) in the control channel (CCH) is waiting to be released.

  For this reason, in Japanese Patent Application Laid-Open No. 8-340572, “Simultaneous incoming call synchronization method, wireless line connection device and wireless terminal” in Japanese Patent Laid-Open No. 8-340572, a plurality of wireless slave units (PS) constituting the same incoming call group are described. As a method for receiving all calls at once, a simultaneous call receiving method has been proposed in which a common incoming call flag (incoming operation instruction bit) is attached to an incoming message channel (PCH) and transmitted. Thereby, it is possible to call a plurality of wireless slave units (PS) at the same time, and proposes a mechanism that can make incoming calls to the second and subsequent wireless slave units (PS) without delay.

JP-A-8-340572 (page 3-4)

  In the incoming call system of the current PHS wireless communication system compliant with the RCR STD-28 standard, as described above, the incoming call message channel (PCH) for notification of incoming calls is a plurality of wireless slave units constituting the corresponding incoming call group. Since only one of the wireless slave units (PS) can be notified among (PS), the individual incoming calls are made individually to a plurality of wireless slave units (PS) in the same incoming call group at substantially the same time. I can't let you.

  That is, the incoming call notification for the next wireless slave unit (PS) is not executed until the incoming call message channel (PCH) used for the incoming call notification to any one of the first wireless slave units (PS) is released. . In particular, when the first called wireless slave unit (PS) is in a power-off or out-of-service state, the incoming call message channel (PCH) is not immediately released, so the next wireless slave unit (PS) Incoming calls are greatly delayed.

  In order to solve such a problem, as described above, Patent Document 1 proposes a method of simultaneously receiving a plurality of wireless slave units (PS) constituting the same incoming call group (simultaneous incoming call method). Then, a proposal has been made to transmit an incoming call flag common to a plurality of wireless slave units (PS) through an incoming call message channel (PCH). However, in the case of the simultaneous incoming call system as in Patent Document 1, it cannot be applied in a situation where individual incoming calls frequently occur for a plurality of wireless slave units (PS).

  The present invention has been made to solve such a problem, and even when individual incoming calls are generated for a plurality of wireless slave units (PS) constituting the same incoming call group, the respective wireless slave units are provided. PHS wireless communication system, wireless communication control device, wireless slave unit, PHS wireless communication method, and PHS wireless communication having a mechanism that does not cause waiting for an incoming message channel (PCH) for individually calling (PS) The object is to provide a program and a program recording medium.

  In order to solve the above-described problems, the PHS wireless communication system according to the present invention employs the following characteristic configuration.

  (1) A PHS wireless communication system including a wireless communication control device that controls wireless communication performed between a base station and a wireless slave unit based on a PHS (Personal Handy-phone System) standard, The communication control apparatus includes one or a plurality of the incoming message channels that each of the base stations has as an incoming message channel (PCH) for transmitting an incoming call notification from the base station to the wireless slave unit. A PHS wireless communication system that controls to assign one-to-one the incoming call message channels of the different base stations for each of the wireless slaves waiting for the incoming call message channel.

  According to the PHS wireless communication system, the wireless communication control device, the wireless slave, the PHS wireless communication method, the PHS wireless communication program, and the program recording medium of the present invention, the following effects can be obtained.

  Since the incoming call message channel (PCH) for notifying each wireless slave device (PS) is individually assigned in a one-to-one correspondence with each wireless slave device (PS). Even when there is an individual incoming call to a plurality of wireless slave units (PS) belonging to the same incoming call group at substantially the same time, without waiting for a free call message channel (PCH) for notification of incoming call, An incoming call message channel (PCH) can be immediately transmitted individually to each wireless slave unit (PS), and incoming notification can be performed at high speed.

(Description of operation of embodiment)
Next, as an example of the operation of the PHS wireless communication system in FIG. 1, each incoming message channel (PCH) from each base station (CS) is stored in the “incoming message channel (PCH) table” of the wireless communication control device 10. An example of the operation of registering the PS number of the standby wireless slave device (PS) will be described with reference to FIGS. 3, 4, and 5. FIG.

  FIG. 3 shows a radio in which each incoming message channel (PCH) from each base station (CS) is stored in the “incoming message channel (PCH) table” of the wireless communication control device 10 in the PHS wireless communication system shown in FIG. FIG. 7 is a sequence diagram showing an example of an operation sequence for registering a PS number of a slave unit (PS), taking a base station CS1 as a standby target base station (CS) by taking the case of a radio slave unit PS1 as an example ) Shows the sequence when selected as.

  FIG. 4 shows a radio in which each incoming message channel (PCH) from each base station (CS) is stored in the “incoming message channel (PCH) table” of the wireless communication control device 10 in the PHS wireless communication system shown in FIG. It is a flowchart which shows an example of operation | movement in a radio | wireless subunit | mobile_unit (PS) at the time of registering PS number of a subunit | mobile_unit (PS). FIG. 5 also shows each incoming message channel (PCH) from each base station (CS) in the “incoming message channel (PCH) table” of the wireless communication control device 10 in the PHS wireless communication system shown in FIG. It is a flowchart which shows an example of operation | movement in the radio | wireless communication control apparatus 10 at the time of registering the PS number of the radio | wireless subunit | mobile_unit (PS) to receive.

  First, the wireless communication control device 10, base station CS1, and wireless slave device PS1 when registering the PS number of the wireless slave device PS1 that waits for each incoming message channel (PCH) in the “incoming call message channel (PCH) table”. An example of the exchange of control signals between them will be described with reference to the sequence diagram of FIG. A control signal between the base station CS1 and the wireless slave unit PS1 is transmitted and received in the uplink direction from the wireless slave unit PS1 to the base station CS1 using an individual cell signal control channel (SSCH). Further, the downlink direction from the base station CS1 to the wireless slave unit PS1 is transmitted / received using an incoming call message channel (PCH).

  In FIG. 3, when the base station CS1 is first selected as a candidate for a base station (CS) on which the wireless handset PS1 waits for an incoming call message channel (PCH) for notification of incoming calls, the wireless handset PS1 transmits to the base station CS1. The incoming call message channel (PCH) registration request is transmitted using the signal control channel (SSCH) (sequence Seq1). Receiving the incoming call message channel (PCH) registration request, the base station CS1 transfers the incoming call message channel (PCH) registration request received from the wireless slave unit PS1 to the radio communication control apparatus 10 as a main apparatus (sequence Seq2). ).

  Receiving the incoming call message channel (PCH) registration request from the wireless slave device PS1 via the base station CS1, the wireless communication control device 10 activates the incoming call message channel (PCH) table registration process (sequence Seq3). Of the incoming call message channel PCH1 to incoming call message channel PCH4 in the transfer source base station CS1, the incoming call message channel (PCH) to be assigned to the incoming call group indicated by the PS number of the wireless slave unit PS1 of the registration request source (this embodiment) In the embodiment, the incoming message channel PCH1 corresponds).

  By searching the “incoming message channel (PCH) table” using the incoming message channel PCH1 of the base station CS1 obtained as a result of the calculation, the incoming message channel PCH1 of the base station CS1 is in an empty state. If not assigned yet to the wireless slave device (PS), the incoming call message channel PCH1 of the base station CS1 is registered as an incoming call notification channel (PCH) for notification of incoming calls to the registration request source wireless slave device PS1. .

  If the incoming call message channel PCH1 in the base station CS1 has already been assigned to another wireless slave unit (PS) and is not an empty channel, the incoming call message channel of the registration request source wireless slave unit PS1 ( (PCH) registration is rejected.

  After that, the radio communication control apparatus 10 generates a PCH registration permission / rejection signal indicating whether or not the registration of the “calling message channel (PCH) table” is successful, and receives the incoming message channel (PCH) registration request. To the transmission source base station CS1 (sequence Seq4). The base station CS1 that has received the PCH registration permission / rejection signal uses the incoming call message channel (PCH) to transmit the PCH registration permission / rejection signal received from the wireless communication control apparatus 10 to the wireless slave device PS1 that is the registration request source. (Sequence Seq5).

  The wireless handset PS1 that has received the PCH registration permission / rejection signal determines whether or not the incoming call message channel (PCH) has been successfully registered, based on the received PCH registration permission / rejection signal. If the registration of the base station CS1 selected as a candidate for the reception is successful, the reception gate Rx is set to a reception state in which the reception gate Rx is turned on at a timing synchronized with the transmission timing of the incoming message channel PCH1 from the base station CS1. . On the other hand, if the registration of the base station CS1 as the standby base station fails, the wireless handset PS1 selects the next base station (CS), for example, the base station CS2, as the standby base station candidate, and then selects the next base station (CS) For example, an operation of transmitting an incoming call message channel (PCH) registration request to the base station CS2 is performed, and registration of a standby base station that waits for an incoming call notification incoming call message channel (PCH) is successful. The above operation is repeated.

  Next, the operation in the wireless slave unit (PS) when registering the PS number of the wireless slave unit (PS) waiting for the incoming call message channel (PCH) for notification of incoming calls in the “incoming call message channel (PCH) table” An example will be described with reference to the flowchart of FIG.

  In the flowchart of FIG. 4, when the wireless slave device (PS) first selects and determines a candidate for the base station (CS) that waits for the incoming call message channel (PCH) (step S1), the wireless slave device PS1 receives the standby candidate. An incoming call message channel (PCH) registration request is transmitted to the base station (CS) using the signal control channel (SSCH) (step S2). The standby candidate base station (CS) that has received the incoming call message channel (PCH) registration request transfers the received incoming call message channel (PCH) registration request to the radio communication control apparatus 10 as the main apparatus.

  Upon receiving the incoming message channel (PCH) registration request transferred from the standby candidate base station (CS), the radio communication control apparatus 10 is designated by the incoming call message channel (PCH) registration request. Whether or not the incoming call message channel (PCH) of (CS) can be assigned as a channel for notification of incoming calls of the wireless slave unit (PS) that is the registration request source is determined as an incoming call message channel (PCH) table registration process. As an execution result of the incoming call message channel (PCH) table registration process, the incoming call message channel (PCH) from the base station (CS) that is the standby candidate for incoming call notification by the wireless slave device (PS) that is the registration request source PCH registration permission / rejection signal indicating whether or not waiting for the incoming call message channel ( Through CH) base station of the transfer source of standby candidate registration request (CS), coming back to the registration requesting radio personal station (PS).

  The wireless slave device (PS) that has transmitted the incoming call message channel (PCH) registration request uses the incoming call message channel (PCH) via the base station (CS) selected as the standby candidate, and the wireless communication control device 10 The PCH registration permission / rejection signal returned from the terminal is waited (step S3), and when the PCH registration permission / rejection signal is received (YES in step S3), the wireless communication control device 10 receives the standby candidate base station (CS). It is confirmed whether or not it is permitted to register the incoming call message channel (PCH) in the “incoming call message channel (PCH) table” (step S4).

  When the registration is permitted by the wireless communication control device 10 (YES in step S4), the base station (CS) selected as the standby candidate is set to the standby base station that waits for the incoming call message channel (PCH) for notification of incoming calls. Then, the reception gate Rx is set to a reception state in which the reception gate Rx is turned on at a timing synchronized with the transmission timing of the incoming message channel (PCH) from the standby base station (CS).

  On the other hand, if the registration is rejected by the wireless communication control device 10 (NO in step S4), the standby candidate base station (CS) is changed and reselected (step S6), and then the process returns to step S1. Until the registration of the standby base station is successful, the operation of transmitting an incoming call message channel (PCH) registration request to the newly selected standby candidate base station (CS) is repeated.

  Next, an example of the operation in the wireless communication control apparatus 10 when registering the PS number of the wireless slave unit (PS) waiting for the incoming message channel (PCH) in the “incoming message channel (PCH) table” is shown in FIG. This will be described with reference to the flowchart of FIG.

  In the flowchart of FIG. 5, when the wireless communication control device 10 receives an incoming call message channel (PCH) registration request from the wireless slave device (PS) via the standby candidate base station (CS) (step S11), The incoming message channel (PCH) table registration process is started, and the PS of the wireless slave device (PS) that is the registration request source among the incoming message channels PCH1 to PCH4 in the standby candidate base station (CS). An incoming call notification message channel (PCH) to be assigned to the incoming call group indicated by the number is calculated.

  By searching the “incoming message channel (PCH) table” by the incoming call message channel (PCH) for incoming call notification of the base station (CS) of the standby candidate obtained as the calculation result, the incoming call message for the incoming call notification is searched. If the channel (PCH) is empty and has not yet been assigned to another wireless slave unit (PS) (YES in step S12), the base station of the standby candidate calculated as the incoming call notification channel ( CS) incoming call message channel (PCH) is registered in the “incoming call message channel (PCH) table” as an incoming call message channel (PCH) for notification of incoming calls to the wireless slave device PS1 that is the registration request source. Wait for incoming call notification to the wireless slave unit (PS) that is the source of the call message channel (PCH) registration request Transmitting the PCH registration permission signal indicating that registered the call message channel (PCH) of the candidate base station (CS) (step S13).

  On the other hand, in the “incoming call message channel (PCH) table”, the incoming call message channel (PCH) of the standby candidate base station (CS) calculated as the incoming call notification channel is not an empty channel but is already in another state. If it is assigned as an incoming call message channel (PCH) for notification of incoming calls to the wireless slave unit (PS) (NO in step S12), it is registered in the “incoming call message channel (PCH) table”. And the incoming call message channel (PCH) of the standby candidate base station (CS) for notification of incoming call to the wireless slave unit (PS) that is the transmission source of the incoming call message channel (PCH) registration request. A PCH registration rejection signal indicating that registration has been rejected is transmitted (step S14).

  By performing the operations as shown in FIG. 3 to FIG. 5 described above, each wireless slave unit (PS) is individually distributed for each incoming message channel (PCH) unit of each base station (CS). Thus, it is possible to wait for the presence or absence of an incoming call, and even if a plurality of wireless slave units (PS) belonging to the same incoming call group are received substantially simultaneously, each wireless slave unit (PS) In contrast, it is possible to notify the incoming call without delay.

  That is, in the PHS wireless communication system shown in FIG. 1, for example, a registration result of an “incoming message channel (PCH) table” as shown in FIG. 2 is obtained, and as a result, as shown in FIG. Incoming call message channels (PCH) for individually receiving incoming calls for the respective wireless slave devices PS1 to PS9 can be allocated to the incoming call message channels PCH1 to PCH4 of the respective base stations CS1 to CS3. Incoming calls to each wireless slave unit (PS) can be distributed and waited. FIG. 6 is a schematic diagram schematically showing an example of an allocation state of an incoming call message channel (PCH) for each wireless slave device (PS) in the PHS wireless communication system shown in FIG. 1, and each wireless slave device (PS). An example of an allocation state of an incoming call message channel (PCH) when an incoming call notification is individually performed for each is shown.

  For example, in FIG. 6, when there is an incoming call to the wireless slave device PS1, the wireless communication control apparatus 10 refers to the “incoming message channel (PCH) table” as shown in FIG. 2 to the wireless slave device PS1. By extracting that the incoming call message channel (PCH) for notifying the incoming call is the incoming call message channel PCH1 of the base station CS1, the wireless slave unit using the incoming call message channel PCH1 is sent to the base station CS1. A signal instructing notification of incoming call to PS1 is transmitted.

  Here, even if an incoming call to the wireless slave units PS5 and PS9 belonging to the same incoming call group as the wireless slave unit PS1 occurs almost simultaneously with an incoming call to the wireless slave unit PS1, the radio communication control apparatus 10 is shown in FIG. Referring to the “incoming call message channel (PCH) table” as described above, the incoming message channel (PCH) to the wireless handset PS1 is the incoming call message channel PCH1 of the base station CS1, and It is extracted that the incoming message channel (PCH) is the incoming message channel PCH1 of the base station CS2, and the incoming message channel (PCH) to the wireless slave device PS9 is the incoming message channel PCH1 of the base station CS3. Will do.

  Therefore, as indicated by the thick solid arrows in FIG. 7, the radio communication control apparatus 10 receives incoming calls for the radio slave units PS1, PS5, PS9 via the incoming call message channel PCH1 to the base stations CS1, CS2, CS3, respectively. Signals instructing notification are individually transmitted, and each base station CS1, CS2 and CS3 uses the incoming message channel PCH1 for notification of incoming calls as indicated by the thick broken line arrows in FIG. The incoming notification can be transmitted almost simultaneously to each of the machines PS1, PS5 and PS9 without delay.

  Here, FIG. 7 shows an example of the transmission status of the incoming call message channel (PCH) when the PHS wireless communication system shown in FIG. FIG. 5 is a schematic diagram for explaining, and incoming call message channels PCH1 for notifying incoming calls to wireless slave devices PS1, PS5, PS9 belonging to the same incoming call group are individually and substantially simultaneously transmitted from base stations CS1, CS2, CS3. An example of transmission is shown.
