Basic Information of Capacity

Planning Compared with the CS services, GPRS/EDGE features higher

efficiency and utilization of radio resources. It is applicable to

the services with the following features：

Burst data transmissions at intervals much longer than the

transmission delay

Frequent data transmissions with a small amount of data, such

as several transmissions per minute and less than thousands of

bytes per transmission.

Infrequent data transmissions with a large amount of data,

such as several transmissions per hour and more than tens of

thousands of bytes per transmission.

Traffic Model

Currently, GPRS/EDGE and GSM share the CCCH. If the PCCCH

access mode is used, there are great changes in the signaling

channel planning, parameter planning.

It is difficult to accurately predict the GPRS/EDGE traffic model,

because the GPRS/EDGE traffic model cannot be described

simply by traffic volume (Erlang) per user.

The GPRS/EDGE traffic model should be modified with the

development of new services. In addition, the risk of traffic

model mutation due to the introduction of new services should

be avoided.

Traffic Model

Pay attention to the following contents of the

GPRS/EDGE traffic model:

User model: total traffic volume of data services,

proportions of different services, distribution of services by

time, and distribution of services by space

Traffic model: length of packet and interval between

packets of a single service.

Radio transmission model: coding scheme distribution and

signaling overhead

Calculate the average bearing rate over the IP layer according

to the data rate of each coding scheme and the ratio of each

coding scheme to the overall coding schemes.

Calculate the bandwidth of each GPRS channel.

Calculate the traffic volume per GPRS MS in busy hours

Determine whether the CS services and PS services are limited

under a certain number of MSs.

Use the double Iterative algorithm to calculate the maximum

number of MSs in a cell.

Calculate the number of PDCHs occupied by GPRS services.

Coverage Planning

The valid coverage area is subject to two parameters: signal-

to-noise ratio (C/N) and signal strength. C/N determines the

signal transmission quality (bit error rate BER or block error

rate BLER). The coverage area analysis is based on the

similarity between the two parameters in the GPRS system and

the two parameters in the GSM system.

For different coding schemes on the same channel, the BERs

are different. For the same BER on the same channel, the

coverage areas under different coding schemes are different.

The BER performance mentioned later refers to the BLER.

Coverage Planning

Compared with the GSM network coverage, the GPRS/EDGE

network coverage has the following characteristics:

Same EIRP

Except the body loss, other loss between the transmit end and the

receive end is the same as that in the GSM system.

The GPRS/EDGE services are mainly affected by the C/I instead of

the receiver sensitivity. CS-3 coverage area

When the BLER is lower than 10%, the network coverage

in CS1 coding scheme is the same as the network

coverage of speech services.

speech services.

The quality and C/I relationship

When the BLER in CS1 coding scheme is lower than 10%, the requirement

is the same as the C/I requirement of voice quality level 4.

When the BLER in CS2 coding scheme is lower than 10%, the requirement

is the same as the C/I requirement of voice quality level 3.

Therefore, you can analyze the GPRS network coverage based on the

existing GSM network coverage and voice quality. In CS1 coding scheme,

the coverage area of the GPRS network is almost the same as that of the

GSM network. In CS2 coding scheme, as the C/I is improved, the coverage

area of the GPRS network is about 80% of that of the GSM network.

Frequency Planning

Determine the frequency reuse pattern based on the C/I

requirement, capacity planning requirement, and

available bandwidth.

The requirement of capacity planning in the early stage is

not high. According to the coverage planning, the C/I of

TCH on the BCCH meets the requirement of GPRS services.

If the PDCH is configured on the TRX carrying the BCCH,

factors such as 1X3, 1X1, MRP, concentric cell, frequency

hopping, and power control need not be considered

during frequency planning.

Page44


35pt

32pt

) :18pt

Frequency Planning

On the existing network, the BCCH carrier does not use

the power control, DTX, frequency hopping techniques.

The 4X3 frequency reuse pattern is used. Therefore, the

advantages of PDCH configuration on the BCCH

frequency are as follows:

The C/I can meet the requirement of GPRS network

coverage.

There is no additional interference brought by data services

to the GSM services.

If the TRX carrying the BCCH is configured with baseband

frequency hopping, considering the multi-timeslot capability

of the GPRS MS, all the PDCHs must have the same MAIO Page45


Network Planning

) :18pt

Frequency Planning

If the PDCH is configured on the non-BCCH frequency, as

the TCH uses the power control, DTX, tight frequency

reuse, and concentric cell techniques,

The C/I probably cannot meet the requirement of GPRS

network coverage.

Data services may bring about addition interference to the

GSM services. This will decrease the service area of the

speech services.

If frequency hopping is used, the PDCHs on the same TRX

must have the same MAIO and HSN. However, for the GPRS

network, frequency hopping does not have the benefits as

expected. Page46


35pt

) :18pt

Frequency Planning

When the PDCHs are insufficient even if all the TCHs on

the BCCH are configured as PDCHs, can configure PDCHs

on other TRXs. In this case, use frequency hopping to

reduce the MS' requirement on C/I

When the EDGE network is configured with baseband

frequency hopping, all the TRXs participating in the

frequency hopping must support EDGE services.

When calculating the increment of paging channels, you

need to consider that the CS paging messages of some

PDPACTIVE GPRS MSs will be retransmitted because

these MSs cannot listen to the PCH during the data

transfer process.

According to the current network conditions, the

capacity expansion of the RACH and PCH is unnecessary.

However, more AGCHs should be configured to support

the GPRS services.

Page52

) :18pt


To avoid AGCH congestion, you can use the following

methods:

Use non-combined CCCH configuration mode. Increase the

number of reserved AGCH blocks (pay attention to the PCH

load). Configure multiple non-combined CCCHs.

Use PCCCH as early as possible.

The allocation of the routing area (RA) also affects the

planning of signaling channels. Currently, the RA can be the

same as the LA.

However, with the increase of GPRS users, the RA size and the

number of packet paging messages should be reduced to

decrease the PCH load.

Check whether the PCH is overloaded and whether the traffic

volume of packet paging is oversized according to the traffic

measurement results, and then determine whether to re-

allocate the RA .

network is as follows ：

In the dual-band network, if the traffic on the GSM1800

network are preferred, the GPRS/EDGE services are

concentrated on the GSM1800 network, leading to network

congestion. However, the network cannot use the service

handover method as used in the GSM network to switch the

traffic to the GSM900 network.

The coverage of the GSM1800 network is poor, which

affects the quality of the PS services. However, the network

cannot actively switch the traffic to the GSM900 network.

To solve the problem of GPRS/EDGE traffic congestion on

the GSM1800 network, use the following methods :

Configure more dynamic PDCHs on the GSM1800 network.

When the GPRS/EDGE traffic congestion on the GSM1800

network occurs, trigger the handover of the speech services

occupying the dynamic PDCHs to the GSM900 network.

The dynamic PDCHs released after the handover can be

used for the GPRS/EDGE services.

GPRS throughput should be CS1 to 4 and EDGE should

support MCS1 to MCS9. Also be able to cater for 2 TS in

the uplink direction and 4 in the download direction.

Expect averages of 100 Kbits for GPRS and 250 Kbits for

EDGE (UL: 30% and DL:70%) for each subscriber under

high load.
