2 Overview
2.1 Feature Introduction
Every cell under the management of ZXG10 BSS can acquire the authority to activate the
Enhanced Data rates for GSM Evolution (EDGE) service through configuration. Flexible
configuration mechanism enables operators to determine whether to activate EDGE or
retain existing functions based on user demands in every cell.

This cell-based configuration properly utilizes resources and efficiently lowers costs.
2.2 Correlation with Other Features
None.
3 Technical Description
Enhanced General Packet Radio Service (EGPRS) adopts an 8-PSK modulation mode,
which enhances data throughput capability and delivers faster transmission rates for
users.
ZTE BSS is already EGPRS-capable in terms of hardware. It also supports flexible
setting of EGPRS in terms of software. The activation of EGPRS is cell-based, that is, if a
cell is set to “Support EDGE”, all users in this cell can initiate EGPRS. ZTE BSS allocates
radio and ABIS resources based on user requests and cell configurations to support the
high rate data service.
Therefore, operators can activate or deactivate the EGPRS function based on their actual
needs. This realizes more flexible configuration and more appropriate resource
utilization.

4.2 Parameter Configurations
Log in to the configuration management interface.
In the configuration resource tree window, select [OMC → GERAN Subnetwork →
BSC Managed Element → Config Set → BSC Function → BTS Config → BTS ID],
and double-click [Cell ID]. In the displayed [Cell] window, select the [Basic Parameter 1]
tab and set “Support GPRS” to “Support EDGE” to activate the EDGE of the cell, as
shown in Figure 4-1.

There are no counters for this function.
5.2 Related Alarms
There are no relevant alarms for this function.
6 Engineering Guide
6.1 Application Scenario
This function is applicable to the places where the activation of EDGE service is required.
6.2 Configuration Description
The precondition for activating this function is that the Gb interface of iBSC is normally
activated.
This function requires the BTS carriers to support EDGE (At present, some old carriers of
V2 BTS do not support EDGE).
6.3 Network Impacts
Impacts on network
The EDGE imposes strict requirements for radio environment and system capacity. The
rate of MCS4 is lower than that of CS4, so forced activation of EDGE may achieve
negative effects. If the current network cannot support EDGE activation in all cells, you
ZGO-03-05-007 EGPRS Activation Per Cell

may activate EDGE in some cells to make full use of resources without any impact on
network.
Impacts on NEs
This function has no direct effect on NEs, but after activation of EDGE, more resources
are needed, including PDCHs, ABIS links and PCU modules. In addition, you need to
check whether the original radio environment can meet the new coding requirements.
