a) OFF-SWITCH OPTIONS

There could be two ways to access the database, making use of the All-Call-Query, or the Query-on-Release techniques.

a. 1 ALL-CALL-QUERY TECHNIQUE

The stemming network very first checks the location of the called qual operadora in the central data source and afterwards routes the call directly to the recipient network.

a. 2 QUERY-ON-RELEASE

The originating network initial checks the status of dialed number with the contributor network. The donor network returns a message to the originating network determining if the number has actually been ported or not. The originating network after that inquires the main data source to get the info pertaining to the recipient network and directs the call straight to the recipient network.

b) ON-SWITCH OPTIONS

The two methods to implement on-switch options are:

b. 1) ONWARD ROUTING (CALL FORWARDING).

Here, the coming from network connects to the contributor network. If the dialed number has been ported, the contributor network itself transmits the call to the recipient network.

b. 2) PHONE CALL HANG BACK.

Here the contributor network checks if the number is ported and also if it is, releases the call back to the coming from network together with information identifying the correct recipient network. The coming from network after that routes the call to the recipient network.

On-switch services are normally considereded as a short-term interim solution for number transportability.

DATABASE MANAGEMENT.

The various technical choices connected to the application of MNP stated above involve using data sources which contain transmitting details. The data sources can be centralized or dispersed.

The centralized model involves a solitary reference database having information for all mobile numbers or alternately, all ported numbers. This recommendation information is usually duplicated to operational databases in each getting involved network on a regular basis. A consortium of network drivers might manage this central number data source for mobile number portability, or it may be out-sourced to a 3rd party.

The dispersed version includes numerous databases consisting of parts of the total information. For instance, in the on-switch situation each different database in the distributed version could comprise only the numbers ported from a particular mobile network driver. The full collection of information about all mobile numbers (or all ported mobile numbers) is only available from these different databases when taken all at once.

CONTRASTING THE TECHNICAL CHOICES.

Forward transmitting is often considered as the simplest transmitting method to apply as well as the all call inquiry approach as one of the most intricate, with the various other techniques lying in between these 2 extremes. This is additionally mirrored in the prices of establishment, with forward routing regarded as more affordable to establish compared to the all call inquiry technique. By contrast, the ongoing costs connected with the all call question technique are typically considered as less than those of the forward directing technique. Again, the expenses associated with the various other two techniques exist in between those of all call inquiry as well as onward directing.

The central database solution is perceived as a long-term consulta operadora option for number transportability. It supports optimum telephone call transmitting as well as is adjusted to an environment where all operators share number information. Nonetheless, it is practically much more complicated to implement, involves significant financial investment (also from operators that are not directly worried about number transportability such as nationwide far away operators selected as indirect access companies), as well as calls for considerable national co-ordination.

OPERATIONAL ASPECTS.

Although the technical execution of number transportability involves specific obstacles, the challenges in devising the administrative arrangements helping with porting of numbers might require equivalent, if not even more, interest. Inefficiently created, complicated or flawed treatments for porting of mobile numbers might work as a traffic jam to the effective application of mobility and badly influence the anticipated advantages.

Creating effective, basic, secure but useful porting procedures for number portability might involve attending to concerns such as the duty of sellers, the should alter SIM cards or handsets, existing client commitments, verification of consumers asking for a port, interaction plans between entities during the porting procedure, rejection to port, time to port, and procedures for porting big amounts of numbers at an offered time. These concerns can be resolved via a Consultation at a later phase.
