12. Principles
All of PHS interface specification documents have following principles.
I)
ii)
iii)
iv)
v)
vi)

PHS networks are able to be applied any network topologies.
PHS networks are able to be constructed from Multi-vendor equipment.
Any operator can use the common one Network as PHS base network.
Any operator can develop unique-supplementary services by oneself.
All of PHS interface specifications can protect each operator' subscriber profile.
PHS interface specifications have capabilities for PHS network to connect any kind of current
networks.
vii) PHS interface specifications can support the functional expansion of Switch, Database and PHS
Public Cell Station.
3. Network Model and Reference Points
This clause indicates the typical PHS network model and reference points, PHS numbering plan.
These explanations are in sub-clauses.
3.1. Network Model and Reference Points
Typical PHS network model and reference points are described in figure 1-1. Figure 1-1 indicates theover view of typical PHS network model, it's means that more detail network model is described as
the part of network model in the General Description B-IFx.x0 of each interface defined document.

In Figure 1-1, each reference point is explained as follows.
IF 1 :PHS Common Air Interface
PHS uses the PHS common air interface. The specifications are described in B-IF1.00
document.

IF 2 :

Public Cell Station - Network Interface
IF 2 is the reference point of interface between Public Cell Station and PHS Switching
Network. The current IF 2 specification is specified as Interface between Public CS - ISDN.
In this case, Network is Integrated Services Digital Network(ISDN). This interfaces are
divided into 2 reference points. These reference points are "T" and "U" reference point.
Basic Rate Interface and Primary Rate Interface are prepared for "T" reference point inaccordance with access rate. This interface specification is described in B-IF2.0X
specifications.
In the future, IF 2 will also include the other types, Non-ISDN interface, be defined in BIF2.xx series interface specification documents.

IF 3:

Network - Network Interface for Call Control
IF 3 is the reference point of the SSP-SSP (CCF-CCF) interface between Networks. In thecurrent PHS network, ISUP of Signaling System No.7 is being used. The coming
description of the specification will be ISUP. The other interface specifications are furtherstudy .

IF 4:

Network - Network Interface for SCP Exchange
IF 4 is the reference point of the SCP/SDP-SCP/SDP (SCF-SDF or SDF-SDF) interface
between Networks. In the current PHS network, INAP of Signaling System No.7 is beingused. The coming description of the specification will be INAP. The other interface
specifications are further study .

IFb, IFc, IFf, IFg:

These interfaces are for further study.

3.2. PHS Service Numbering Plan
PHS number is based on ITU-T Recommendation E.164. ITU-T Recommendation E.164 number
structure is indicated in figure 1-2. General Description of Numbering Plan is in B-NW0.00
document.

4. Further Study Items
4.1 Roaming
The Interface specification about roaming function will be described in IF 3 and IF 4 interface
specification documents. General Description of Roaming is in B-SV1.00 document.
4.2. Supplementary Services
PHS supplementary services are specified for each operator can define fully and uniquely. The
following items are decided for further study items. The other items will be set for further study.
