| Abstract | "Personal Handy-Phone System (PHS)" can be functioned as a digital cordless phone in
homes and offices, and as a cellular phone outdoors. PHS system can be established by either
utilizing an existing .PSTN network or constructing a separate network. This study considers an
impact of PHS system on an existing PSTN signaling network, by calculating the size of PHS
signaling traffic load per hour generated from all key wireless activities as a function of PHS
service penetration, and then compare it with land-line signaling traffic load. To reduce this
impact, this study proposes by reducing the signaling load due to location update and paging
procedure. By increasing the number of cells per location area, the rate of location update is
reduced. By applying an alternative paging strategy (AP), which is ·based on multiple step
paging as well as paging related information of the users, instead of a single step paging, which
is PHS standardization, the unnecessary signaling load due to paging procedure can be reduced.
The major drawback for AP compared to a single step paging is the increased paging delay.
The value of some parameters used in this study are taken from the real case of
establishing a PHS system in Bangkok, Thailand. The real message sizes for all key wireless
activities of PHS have not been available, the GSM figures are used instead. In addition, this
study can be considered as the worst case of PHS, since it is likely that the real message sizes
for all PHS key wireless activities are smaller than for GSM. However, this study does show
that signaling traffic load generated from PHS can have an impact on an existing signaling
network, and the number of cells per location area as well as an effective paging strategy can be
used to reduce this impact. |
