3. Network Function Allocation
3.1 PHS-FWA Elements and Function Allocation
Figure 3-1/C-NW1.00 shows the network elements and the function allocation in PHS-FWA network.
PHS-FWA network is composed of radio access network elements such as WAC/WCS, WSU and
WPS. A typical function allocation using this network configuration is described below.
3.1.1 FWA Access Controller (WAC) and FWA Cell Station (WCS)
WAC/WCS has the function to control network services for PSTN, ISDN and leased line. WAC
controls location registration information, authentication information, and various supplementary
services. WCS controls radio interface. WCS has the radio interface with FWA subscriber unit
(WSU) and FWA personal station (WPS). The radio interface includes interference detection andavoidance functions.
3.1.2 FWA Subscriber Unit (WSU)
WSU is a subscriber unit which consists of radio equipment made up of antenna, transmitter, receiverand so on, and interface to TE or NT.
3.1.3 Terminal Equipment (TE)In the case of PSTN, TE is an existing analogue telephone. TE may support CLIP (Calling Line
Identification Presentation) functionality.
In the case of ISDN, TE is ISDN terminal equipment (ISDN TE).
3.1.4 FWA Personal Station (WPS)
WPS is a user terminal that has the radio interface with WCS.
3.1.5 Service Node (SN)In this document, Service Node (SN) is same as a Local Exchange (LE) for Public Switch Telephone

3.2 Location Registration Procedure
Location registration function includes holding location information of WSU (WPS) and updating thelocation information. "Area Number" is used as location information. The purpose of the location
registration is to inform the location information to database in WAC when WSU (WPS) is located to
the location registration area. Figure 3-2/C-NW1.00 shows an example of location registration
procedure.
(1) WSU (WPS) recognizes the present location registration area by information from WCS.
(2) When WSU recognizes a new location registration area, WSU transmits the location registration
request message to WAC after the authentication procedure is executed.
(3) The location information in WAC is updated.
(4) WAC sends the complete message of the location registration is transferred to WSU (WPS)
through WCS.

3.3 Authentication Procedure
When the necessary function request declared by the user ends, the WAC proceeds the authentication
procedure based on RCR standard STD-28.. Figure 3-3/C-NW1.00 shows an example ofauthentication procedure.

(1) WAC/WCS sends authentication request to WSU (WPS).
(2) WSU (WPS) performs calculation by using an authentication algorithm.
(3) WSU (WPS) sends the authentication response to WAC/WCS.
(4) WAC/WCS verifies the result and permits WSU (WPS) to communicate with SN.

3.4 Interference Avoidance Procedure
The WCS and WSU (WPS) perform continuous line monitoring after a service channel established.
When WCS or WSU (WPS) detects some interfering condition in the using service channel,
interference avoidance procedure based on STD-28 is performed.
Figure 3-4/C-NW1.00 shows an example of channel switching procedure which averts interference.
(1) WSU (WPS) recognizes that the quality of the service channel becomes error condition.
(2) WSU (WPS) sends TCH switching request to WCS. (NOTE1)(3) WCS sends TCH switching indication to WSU (WPS).
(4) WCS and WSU (WPS) start to change channel, and new channel are established.

NOTE1: Unnecessary in case of WCS activation.

NOTE1:
There are four cases described as following.
Bilateral agreement about procedure is necessary between WSU and WCS+WAC.
case1 : En-bloc sending procedure
case2 : Overlap sending procedure
In case of the case 1, WSU once accumulates all dial digits from TE. Then WSU will send Setup
message based on the en-bloc sending procedure, and WAC will send dial digits to SN one by one. So
it takes more long delay time than case2.
The case2 includes following types.
Type1 : Using inband DTMF, after en-bloc sending procedure on WIF2.
Type2 : Overlap sending procedure, using inband DT from SN.
Type3 : Overlap sending procedure, using DT generated locally in WSU.
Type1 : Using inband DTMF, after en-bloc sending procedure on WIF2
When WSU detects off hook condition, WSU initiates the en-bloc sending procedure on WIF2
and connects a pass from WSU to SN. Dial tone is transmitted to TE from SN. Then TE transmits
the dial signal which used DTMF signal. This DTMF signal is sent to the SN through theestablished path.
Type2 : Overlap sending procedure, using inband DT from SN
When WSU detects off hook condition, WSU initiates the overlap sending procedure andconnects a pass from WSU to SN. Dial tone is transmitted to TE from SN. Then TE transmits thedial signal which is received by WSU. WSU sends additional dial information to SN, using
overlap sending procedure.
Type3 : Overlap sending procedure, using DT generated locally in WSU
When WSU detects off hook condition, WSU generates DT locally. Then TE transmits the dialsignal which is received by WSU. WSU initiates the overlap sending procedure.

3.5.2 Howler Tone Sending Procedure
When a call cleared by another terminal, WSU starts the supervisory timer which detects the on-hookcondition of its telephone. If the supervisory timer is expired, WSU sends warning signal i.e. howler
tone to the telephone. Figure 3-7/C-NW1.00 shows an example of howler tone sending procedure.

(1) A disconnect information is sent to SN from a telephone in the condition of connection inprogress.
(2) SN sends the disconnect information is sent to WSU via WAC and WCS to proceed clear callprocedure.
(3) WSU proceeds clear call procedure, and starts the supervisory timer which detect on-hookcondition.
(4) If the supervisory timer is expired, WSU sends the howler tone to a telephone (TE).

Figure 3-12/C-NW1.00 shows an example of meter pulsing signal delivery procedure.
(1) Meter pulsing signal is sent to WAC during communication in progress.
(2) WAC detect the charging signal, and puts in this information to INFOrmation message to WSU.
(3) WAC receives INFOrmation message, and generates meter pulsing signal to TE.

3.6 ISDN Procedure
ISDN service is realized by Type 2 system. In Type 2 system, the communication channels are
established by using public PHS interface, and those channels are act as B channels and D channel ofthe Network. The signaling messages of Layer 2 and/or Layer 3 are transparently conveyed throughthe D channel.
Figure 3-13/C-NW1.00 shows an example of ISDN call set up sequence.

C-NW1.00-04-TSSN(1) Location Registration
Location Registration procedure conforms to sub-clause 3.3 of this specification.
(2) Authentication
Authentication procedure conforms to sub-clause 3.4 of this specification.
(3) D channel establishment
D channel is using a part of 32kbit/s physical communication channel of PHS.
D channel establishment sequence conforms to C-IF2.01.
(4) B channel (B1ch/B2ch) establishment
B channel (B1ch/B2ch) is using 64kbit/s physical communication channel of PHS.
B channel establishment sequence conforms to C-IF2.01.
(5) Layer 1 activation
Layer 1 activation sequence conforms to C-IF1.02, C-IF3.02, C-IF3.03, C-IF3.05.
(6) Call control
In call control sequence, the signaling messages of Layer 2 and/or Layer 3 are transparently
conveyed through the D channel.

3.7 Leased Line Procedure
Leased line service is realized by Type 2 system. In Type 2 system, the communication channels are
established by using public PHS interface.

Location Registration procedure conforms to sub-clause 3.3 of this specification.
(2) Authentication
Authentication procedure conforms to sub-clause 3.4 of this specification.
(3) Pre-connected channel establishment
Pre-connected channel is using 32kbit/s, 64kbit/s and 128kbit/s (= 64kbit/s * 2) physicalcommunication channel of PHS.
Physical communication channel establishment sequence conforms to C-IF2.01.

Appendix A. Example of SequenceThis appendix indicate some examples of message sequence. The Network signaling protocol isassumed to be the signaling system No.7. Network messages are indicated only essential messages
which effect to the FWA network. These figures are intended to complement the description in theproceeding text and do not illustrate all possible situations.
The definition of messages, signals, in-band tones, and timers are described in C-IF series documents.
< NOTE >The timer T15 is equivalent to the timer T5 of C-IF1.01. T35 is equivalent to the release guard timingof C-IF3.01 or re-answer timing of C-IF3.03.
