GPRS: General Packet Radio Service
Written by telecom expert R.J. "Bud" Bates, this straightforward, abundantly illustrated text reveals GPRS s features, functions, and architecture--information crucial whether you re providing or applying GPRS.
TABLE OF CONTENTS GPRS: General Packet Radio Service
System Information Type 13 (SI 13)
SI 13 message is broadcast by the network on the BCCH. The message provides the mobile station with GPRS cell-specific, access-related information. The information in this message should be the same as provided in the PSI 13 message on PACCH. If GPRS is required, the MS reads the SI 13 message. SI 13 may indicate if PBCCH is present in the cell.
If PBCCH is present in the cell, the MS camps on it. If PBCCH is not present in the cell, the necessary system information related to GPRS is contained in the SI 13 message (and extended to the SI 14 and SI 15 messages if necessary).
SI 13 Message Contains One of the Two Indications
If PBCCH is present,
-
Channel description for the PBCCH
-
TN Time slot number used for PBCCH and PCCCHs
-
TSC Training sequence code for PBCCH and corresponding PCCCH
-
ARFCN Nonhopping radio frequency absolute RF channel number
-
Localization of PSI type 1 information
If PBCCH is not present,
-
The routing area code (RAC)
-
Options available in GPRS cell include
-
Network Mode of Operation (NMO) (mode I, mode II, mode III)
-
ACCESS_BURST_TYPE (PRACH on 8 or 11 bits)
-
Network control order parameters (NC0, NC1, NC2)
-
GPRS power control parameters
