GPRS Roaming Exchange (GRX)

The GSM Association (through its GPRS Working Party within the International Roaming Expert Group) has collected information on potential providers of GPRS Roaming Exchange (GRX) services.

The process used for obtaining this information is the RFI Process and is described below.

The information obtained was compiled into a single file, which you can download as a zip file. The format of the file was chosen to allow for easy comparison of the various GRX Providers' answers.*

The information will be updated by the GSM Association upon request by the respective GRX Provider in accordance with these Rules, which also apply, to companies that wish to offer GRX services in the future.

RFI Process

The initial RFI process consisted of 2 rounds:

During the initial round potential GRX Providers were able to describe their future service offerings by answering a few fairly general questions.

Based on the results of the first round a group of experts from the GPRS Working Party (GPRSWP) of the GSMA's IREG compiled a questionnaire containing 83 detailed questions. This questionnaire was sent back to the potential GRX Providers. Additional GRX Providers who did not take part in the first round were able to join in during the second round.

The questionnaire contained two types of questions: those covering basic require-ments and those covering additional aspects.

The potential GRX Providers were requested to answer the question concerning the basic requirements, the other questions were sent in order to give an impression of which additional questions may be put by the GPRS Operators. Answers from the potential GRX Providers were compiled and the results were made available to the GSMA members.

The GPRSWP decided on the future publishing and updating rules for the compiled information

The RFI did NOT cover commercial issues since the individual GPRS Operators entering into a Roaming relationship should negotiate those issues with the GRX Providers directly.

Publishing and Update Rules

1.

The compiled results of the GRX RFI are published on the internet. This requires an initial legally binding statement authorizing the GSMA to "publish the information that has been and will be provided to the GSMA within the GRX RFI process on its public internet web page". Please send those statements to the surface mail address stated at the bottom. In the absence of such authorization the GSMA will not be able to publish the respective GRX Provider's information.

2.

The GSMA is NOT and will NOT be "qualifying", "evaluating", "recommending" etc. GRX Providers. There-fore the GRX Providers shall refrain from giving any such impression when advertising their services. The fact that information on their service offer is published by the GSMA does ONLY mean that they provided it in a format suitable for publication.

3.

There will be an update mechanism for the information as described below:

  • New versions of the results shall be made available as soon as new information is available from any of the previously known and / new GRX Providers.

  • To avoid releasing updated versions in short intervals, new releases shall only be made over the weekend.

  • New releases will include any information received before Friday 08:00 GMT.

  • If no new information has been received no new release will be made.

  • In order to be included in the processing of information, the respective GRX operators have to use the most recent version of the Questionnaire and have to restrain their answers and changes to those fields of the questionnaire that are intended for that.

  • As need arises, the GPRSWP will decide on additions to the Questionnaire.

  • Whenever changes are introduced, the available information of every GRX Provider will be transferred to the new format and the resulting file will be forwarded to the respective GRX Provider.

  • The version number of the answer file ("x.y.z") is used for two different purposes: "x.y" is used to reflect changes to the questionnaire and will only be changed by the GSMA while "z" is to be used by the re-spective GRX Provider to reflect changes to the information content of the answer file. Please remem-ber to increment "z" whenever you submit a new answer file.

  • The compilation of results will be based on the most recent version of the respective answer files.

  • Please send the information to the following email address: Brian Hunter.

  • New GRX Providers may obtain an empty Questionnaire by sending an E-Mail to the address stated at the bottom.

4.

The GSMA will NOT host ANY original material on the GRX Providers due to the effort required to update and test the links. It was decided that the compiled results will include one (1) link to the respective page on the GRX Provider's web site. This link will be contained in the "Contact" worksheet.

5.

The "Contact" worksheet of the compiled results will also contain the date of last update of the information provided by the respective GRX Provider as well as the identification of the answer file. This information will be generated automatically during the compilation process.
