1 GPRS (General Packet Radio Service)

GPRS is a new non-voice value added services that allows information to be sent and received across a GSM mobile telephone network. It supplements today’s Circuit Switched Data (CSD) and Short Message Services (SMS). GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. This gives the option to use a packet-based data service. The information is split into separated but related “packets” before being transmitted and reassembled at the receiving end. Theoretically, maximum speeds of up to 171.2 kilobits per second (kbps) are achievable with GPRS using all eight timeslots at the same time. This is about 3 times as fast as the data transmission speed possible over today’s fixed telecommunications networks and 10 times as fast as current Circuit Switched Data services on GSM networks

Example: Cell with 1 Frequency channel: 1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical channels for Packet switched.

Note: ESD concept; the internal circuits will be more susceptible to ESD because of

the use of exchangeable housing. The construction of the internal block must be/is designed, in the best possible way, to protect the circuit against sparks.

The keypad must be completely closed to prevent any occurrence of an ESD disruptive discharge.

The SIM contacts may be open, thus reachable for ESD contact discharge. This could lead to damage or destruction of the E-Gold pins.

It is a requirement for the service personnel to observe ESD protection rules while performing servicing the M55.

9 Mobile Software Programming

The common mobile software available is divided into language groups. However, this

software does not contain the specific settings, such as ringing tones, greeting text, and

short dial list etc., required by the operator or service provider. Therefore, it is common to

have some menu item(s) differ in different variants or are not visible at all. These settings

are stored in different memory area of the mobile and will be activated depending on the

customer specific model or variant of the phone by a separate test step during the

production process.

Due to this separation of common mobile software and customer specific initialization, it

is possible to fulfil the demands of the market requiring customization and flexibility. As a

consequence the software programming process in the LSO is divided into two different

steps as followed:

- Software update to actual version and appropriate language group

- Programming of CUSTOMER SPECIFIC INITIALIZATION

10 Siemens Service Equipment User Manual

Introduction

Every LSO repairing Siemens handset must ensure that the quality standards are

observed. Siemens has developed an automatic testing system that will perform all

necessary measurements. This testing system is known as:

Siemens Mobile Service Equipment

Using this system vastly simplifies the repair of the phones and will make sure that:

1. All possible faults are detected

2. Sets, which pass the test, will be good enough to return to customer.

Starting from the P35 Series, Siemens will introduce a simpler and faster testing platform

for testing a repaired Siemens mobile phone. The testing platforms are either base on

R&S CMD 53/55 or CTS55 GSM test set.

There is also test software under development for testing with the Wavetek 4201S and

the 4107 GSM test set.

Level 2.5 service software is also under development for more elaborate testing for the

repair for the L55 series mobile phone.

THE LSO WILL HAVE TO PURCHASE THE SYSTEM, CHOOSING BETWEEN THE COMPLETE PACKAGE AND SUB-SET OF IT.

A FULLY AUTOMATIC TEST PROCEDURE IS ONLY POSSIBLE IF THE COMPLETE SYSTEM IS INSTALLED.

Make sure that your CTS firmware is Version 3.01 or higher. For CMD 55 it must be Version 4.03 and higher. Please check with the Service Info SB_0500 for the CTS/CMD Hardware Options.
