As an example, the provisioning required in each equipment for PSTN services is shown in TABLE 11/C-SV1.00.
1.3.

Basic Call Handling

FWA system provides the same function as ordinary telephone network to FWA users. Basic callhandling include calls from a FWA user to a PSTN or ISDN user, from a PSTN or ISDN to a FWA
user, and from a FWA user to the another FWA user.
1.3.1. Basic Call Handling of PSTN
1.3.1.1. Individual Subscriber
FWA system provides individual subscriber service by connecting ordinary telephone to WSU. Basiccall handling of individual subscriber is composed of originating and terminating call handling.
(1) Originating call handling
Originating call is a feature by which a FWA subscriber can make a originating call from TE/WPS; theoutgoing call request includes a number identifying the called user. This request is given to thenetwork en bloc including all the required information.
(2) Terminating call handling
Terminating call is a feature by which terminating calls to a FWA subscriber are presented at theterminal address. Termination to the subscriber is realized paging procedure in air interface. Paging isa feature that pages the WSU/WPS in the location registration area based on the stored location
information, and determines the cell by the response from the terminal. When several WCSs areequipped within a location registration area, paging to all the WCSs in the area simultaneously can beconsidered.
1.3.1.2. PBX Subscriber
WLL FWA system provides PBX service by connecting PBX to WSU. There are two types in startsignal of PBX; loop start and ground start.
(1) Loop Start
Call setup is transmitted from PBX to network with loop signal. The call handling of originating calland terminating call refer to 1.3.1.1(1) and (2).
(2) Ground Start
Call setup transmitted from PBX to network with ground start signal. The call handling of originatingcall and terminating call refer to 1.3.1.1(1) and (2).

2C-SV1.00-02-TS

1.3.1.3. Coin Phone Subscriber
FWA system provides coin phone service by connecting coin phone to WSU. Coin phone service issupported by the transmission of meter pulsing signal. Meter pulsing signal is transferred from PSTN
to WLL FWA , and coin collection signal is returned to inform the acknowledge of coin collection.
1.3.2. Basic Call Handling of ISDN
FWA system provides individual subscriber service by connecting TE or NT to WSU. The callhandling of originating call and terminating call at the point of WIF1, WIF2 and WIF3 refer to CIF1.00 series, C-IF2.00 series, and C-IF3.00 series, respectively.
2.

Supplementary Services

PHS-FWA subscribers will be provided various services as same as PSTN and ISDN subscribers.
2.1.

Supplementary Services of PSTN

2.1.1. Direct Dialing In
Direct Dialing In service is a service to provide a direct call to a user accommodated in PBX. When acall is terminated to the user registered in Direct Dialing In service, Network sends digits information
to PBX through dialing -in link. The call is directly terminated to the user without termination toattendant.
2.1.2. CLIP (Calling Line Identification Presentation)
CLIP is a service which present the calling user’s number to the called user. When CLIP is applicableand activated, the network presents the called user with the number of the calling user at call set-up on
all terminating calls.
2.1.3. Meter Pulsing Signal Transmission
Meter Pulsing Signal Transmission is the function to transfer charging signal from PSTN to WSU tocollect coin. Meter Pulsing Signal Transmission is executed in Coin Phone Service.
2.1.4. Terminating-only Line
Terminating-only Line is the line for terminating calls. Terminating procedure is same as individualcall. Originating call is restricted at SN.
2.2.

Supplementary Services of ISDN

ISDN subscribers are provided certain supplementary services by operating companies. The service
specification is same as the existing ISDN service.
3.

Functional Services for Operators

PHS-FWA system provides network operators with convenient network management functions.
3.1.

Location Registration

C-SV1.00-02-TS

3

Location Registration is a feature by which the identify of WSU/WPS is registered to WAC. The
identify of WSU/WPS is used to deliver calls to the WSU/WPS. This feature is realized within FWAnetwork.
3.2.

Authentication

The authentication is a feature by which the validity of WSU/WPS is confirmed. Authentication
should be executed at each location registration, originating call and terminating call. When aWSU/WPS requires of the network to access it, the network requests to the WSU/WPS to executeauthentication. After the network confirms the validity of the WSU/WPS, it sends the message
indicating acknowledgment to the WSU/WPS, and the WSU/WPS is allowed to access the network.
This feature is realized within FWA network.
3.3.

Interference Avoidance

TCH (Traffic Channel) switching can be switched during conversation to avoid interference in airinterface. The default of TCH switching function is described below.
(1) Switching function within carrier within WCS, among carriers present.
(2) No TCH switching function to other WCS.
(3) No CS-ID designation switching function to other WCS.
(4) No re-calling type connection function to other WCS within paging area.
(5) No re-calling type connection function to other WCS among paging areas.
(Note) Re-call type connection function is option.
3.4.

Analogue Services for PSTN

3.4.1. Howler Tone Sending
Howler Tone is sent to the user who keeps off-hook more than specified time after the call iscompeted, and informs ‘long time off hook’ to the user.

4C-SV1.00-02-TS

3.4.2. Hooking Signal Transmission
Hooking signal from FWA terminal is transferred to PSTN. The examples of PSTN services which areprovided by hooking signal transmission are described below.
(1) Call waiting service(2) Three party call service(3) Malicious call service(4) Call transfer service
3.4.3. DTMF Signal Transmission
There are methods in DTMF Signal Transmission; In-channel DTMF tone sending and Out-channel
DTMF signal transmission. In-channel DTMF tone is sent from TE connected with WSU. Out-channel
DTMF signal is transmitted from WPS.

3.5.

Services of Operation

3.5.1. Emergency Call Connection
Emergency Call Connection depends on operator implementation.
3.5.2. Emergency Call Holding
Emergency Call Holding depends on operator implementation.

The list of PSTN services for PHS-FWA is shown in TABLE 1-2/C-SV 1.00.
