Design, Develop, and Install Central Equipment Identity Register (CEIR) for Mobile Networks in Sri Lanka                                                                     (Download PDF)

1. Overview

 The Telecommunications Regulatory Commission of Sri Lanka (TRCSL) is an independent Government body established in 1997 under the Sri Lanka Telecommunications (Amendment) Act No.27 of with view to regulating the Telecommunications sector in Sri Lanka.

TRCSL regulates telecommunications sector by implementing regulatory policies, granting licenses to operators, setting equipment standards, managing radio spectrum promoting fair competition among the players, and protecting consumers by solving disputes.

There are five mobile operators currently operating in Sri Lanka, namely Dialog Axiata, Mobitel, Etisalat Lanka, Hutchison Lanka and Bharti Airtel Lanka.

2. Introduction

International Mobile Equipment Identity (IMEI) is a unique identification code for each mobile device. The IMEI is a 15 digit number that is used to identify the device. The IMEI also reveals the manufacturer, make & model, type approval details and country of production.

The Equipment Identity Register(EIR) is a database that contains a list IMEIs of mobile terminals which are active in a mobile network. EIR maintains a white, grey and black list. The white list is composed of IMEIs of mobiles that are permitted for use. The gray list consists of devices that does not conform to the standards but could be permitted to connect under supervision or triggering an alert. The black list contains IMEIs of devices which have been reported stolen or lost and they are be denied access to the network.

3. Purpose

The theft of mobile phones has become an increasingly serious problem in Sri Lanka. The theft of mobile phones is not just a financial loss but also a threat to personal life of the citizens as well as national security as the vital information stored in the stolen mobile phones are prone to misuse.

Presence of counterfeit mobile phones in the market is an another issue for telecom regulators around the world where Sri Lanka is no exception. A substantial number of counterfeit mobile phones are active in our mobile networks with fake IMEI numbers. They are illegal copies of popular brands and models of mobile phones and do not carry a valid and unique IMEI(ie. no IMEI, all zero IMEI or same IMEI). Counterfeit mobile phones congest mobile networks thereby affecting the quality of service to consumers. They can pose health risks to the users as they have not been tested against safety standards and may emit higher level of radiation than recommended.

Mobile network Operators are expected to deploy EIR in their individual networks to determine whether mobile terminals (e.g. mobile phones, laptop data cards, etc.) registered with them are genuine, authorized and not defective. However, none of the mobile Operators in Sri Lanka has deployed EIR in their networks from the inception.

4. Objective

With the aim to curtail the counterfeit mobile phone market, discourage mobile phones theft and protect consumer interest, TRCSL intends to implement Central Equipment Identify Register (CEIR) that connects to the IMEI database of   all the mobile Operators. CEIR acts as a central system for all network Operators to share black listed mobile terminals so that devices blacklisted in one network will not work on other networks even if the Subscriber Identity Module(SIM) card in the device is changed.

TRCSL now invites qualified consulting firms to submit Expressions of Interest(EOI) to   design, develop, and install CEIR that will determine the status of the IMEIs of the mobile terminals being used in Sri Lanka.

5. Scope of Work 

The Consulting firm shall   design, develop, and install CEIR that performs the following functions:

i. CEIR shall have a capability to maintain the database of IMEIs of all the devices registered on the mobile networks;

ii. CEIR shall be able to identify IMEIs such as;

             a.IMEIs which are not allocated

             b.IMEIs which are null, duplicate or all zero

iii. Database of CEIR shall contain the following information of the devices that registered with all mobile networks in Sri Lanka;

            a.  IMEIs

            b.  IMEI status (white, grey, black)

            c.  Date of record creation

            d.  Date of last record update

            e.  Device model number

            f.  IMEI status reason (invalid, stolen, cloned, valid)

iv. CEIR shall be able to block services to subscribers with registered devices with invalid or blacklisted IMEIs;

v. CEIR shall be able to identify the device model, version and other information;

vi. CEIR shall allow the creation of a new record in the database containing the IMEIs whenever a new subscriber account is activated;

vii. CEIR shall make available Operators’ updated local black/white/grey list database information so as to prevent cloning across networks and keeping database information up to date;

viii. CEIR shall be updated periodically IMEI database with the latest information on valid IMEI assignments by the most efficient method available;

ix. CEIR shall have facility to access GSMA’s IMEI database and shalla capability to identify counterfeit IMEIs by comparing the IMEIs database provided by the GSMA;

x. CEIR shall be interoperableall the appropriate network elements and interfaces of mobile Operators;

xi. Database shall support a flexible method of input (via manual entry of data, flat file containing IMEI range updates;

xii. CEIR shall perform a check on the IMEI format to verify it is of a valid format and range.

6. Qualifications of the Consulting Firm

The Consulting firms should have relevant knowledge and experience in the mobile communications sector particularly technical, operational, and regulatory aspects of successfully implementing CEIR.

Interested consulting firms should provide information indicating that they are qualified to perform the services (brochures, description of similar assignments, experience in similar conditions, availability of appropriate skills among staff, CVs etc.).

7. Selection Procedure

The EOIs received will be reviewed and the highest-ranked consulting firms will be invited to submit detailed Technical & Financial proposals for the assignment. The ranking of consulting firms will be primarily based on their experience and capacity in carrying out this type of consultancy.

In assessing the EOIs consideration will be given to the following: -

i.  Company Profile: Copies of documents defining legal status of the firm to be submitted;

ii. Previous Experience: Submit list of similar assignments previously carried out indicating amount for each  assignment, name of the client and contact addresses and year of completion of the project;

iii. Qualification and experience of key staff: Certified copies of Cvs to be submitted;

iv. Financial Position: Consulting firm is expected to be financially sound to undertake the assignment. They are required to submit Audited financial statements of past three years to prove financial soundness of the firm to carry out the assignment;

v. Any other relevant information for evaluation.
