 Hello friends, myself, Darshan Pandit, assistant professor, department of computer science and engineering from Waltron Institute of Technology, Sulapur. So today we are going to discuss about mobile number portability. So at the end of the session, student will be able to explain the concept of mobile number portability and the process for switching service provider. So in this we are going to learn about mobile number portability, its introduction, types of mobile number portability, basic terminologies in mobile number portability, number portability process and process to switch service provider in India. So mobile number portability offers the subscriber the flexibility to retain his telephone number even when he switches to another operator in service area. So the number portability is a feature that allows a mobile subscriber to use same number across different service provider. The person or a user has the liberty to opt any service provider without time consuming exercise of letting the rest of the world know about the change of the number. So let us see the challenges in mobile number portability. So first is huge cost. So the telecom service sector in India requires an investment of 50,000 crore over next three year to meet the growing demand of GSM. A substantial share would be required for the mobile service market. So the GSM service provider are not yet to justify the huge investment made in the field of MNP. So the next is customer retention or increased competition. So here the service provider are not on guard against the risk of losing customer and revenue in post MNP area. So infrastructure upgrade to support MNP a company has to upgrade both its hardware and software capability which will amount to some cost. So cost recovery and build reconciliation or query processing. So that is when customer plans to shift the old service provider has to perform a query to identify if there is any billing amount pending which they need to recover before subscriber moves to the new service provider. So these are the challenges in MNP. So next are types of MNP. So first is location based which enables a mobile subscriber to use same number when shifting from one geographical area to another. So operator based makes it possible for a mobile subscriber or a fixed telephone subscriber to shift from one mobile service provider to another but in same area and written is original number two. Service based enables subscriber of a company to use same number across different mobile technologies that is it may be GSM technology or CDM technology but it is based in wireless local loop. So next is convergence based. So this allows usage of same number while shifting from fixed to mobile telephone. So lastly total number portability. So this enables usage of same number across different technologies, different geographical region and different national boundaries but ultimate aim is of number portability. So it will also allow the user to implement and would require a collaborated effort on a global scale among different service provider. So it is a combination of different types of portability option. Just think and write what is mobile number portability. So number portability is a feature which allows mobile subscriber to use same number across different service provider. So these are the basic terminologies in mobile number portability. So the first is donor network. So it is an initial network where number was located before being ported. Originating network. So it is a network where calling party is connected. Recipient network is a network where number is located after being ported. So database it is a data store of a ported number with the relevant routing number. Routing number is a specific number that is derived and used by the network to route the call towards the ported number. New service provider. So it is a recipient carrier that is a new service provider to which a subscriber wish to subscribe. New service provider is a donor carrier is a old service provider which subscriber wish to leave. Number portability administration center and PAC. So is an authority responsible for maintaining number portability solution in different region. So here in terminology both OSP and NSP that is old service provider and new service provider carrier will have access to their own wireless network, order entry and point of sale terminal. So these are the elements of MNP that is mobile number portability, clearing house, MCH and its disaster recovery site. So it shall receive a MNP request from a recipient operator and forward it to the donor operator for verification. So NPDatabase and its disaster recovery site with security provision. So here MCH will send all details of number portability database and update its own database by appropriate routing number which is also known as location routing number LRN. So it uses logical centralized database with regionally located database with setup and managed by third party operators. So this logical centralized approach may serve as a common platform for ordering provisioning and notification process for number portability. So NPDatabase at operator end, so here service provider can deploy its separate local MNP database and connect it to the central MNP database through its number portability gateway. That is we can use the gateway, NPDatabase at operator end. So here service provider can connect it gateway to central MNP database of mobile number portability service provider and perform MNP querying. So NP process it is one stop shopping process or two stop shopping process. So here in one stop shopping process customer only needs to contact the recipient operator and authorize this operator to handle the porting. So in two stop shopping process the customer request the existing mobile operator and cancel the contract of old operator with the and generate porting authorization code. So this is done in first step and in second step the customer apply new contract with new operator and ask him to port his number with the porting authorization code. So these are the two steps followed in two stop shopping process. So the figure shows NP process so which consist of three phases negotiation phase, activation phase and porting phase. So the negotiation phase consist of the mobile subscriber who fills the application form for number porting. So it is sent to the recipient network. So from recipient network number porting request is sent to mch and mch will response to the recipient network and forward the request to the donor network and donor network request acknowledgement will be sent to the mch and mch will send number porting request acknowledgement response to the donor network and the recipient network in step 7. So this all seven steps are followed in negotiation phase. So in step 8 service disconnect from mch is sent to the donor network and service disconnect acknowledgement is received by mch from donor network. After that service connect is received from recipient network to mch and service connect acknowledgement is sent back to the recipient network from mch. So this all done in activation phase. So lastly the porting phase so that is donor network sends service connect notice to the all service providers after that service connect notice acknowledgement is received to the donor network and recipient network in the porting phase. So this is how porting is done. So this is the procedure to switch service provider in India. So first send an sms port space your mobile number to 1900 so that you will get an reply sms with a unique porting code from 1901 after that you need to submit an application to service provider where you want to shift along with your id proof address proof and photograph. After that in step 3 your application will be processed by new service provider and you will get an application received confirmation and details of porting date. So in next seven days mch will check whether you have any outstanding dues and then process your request. So once your porting is completed you will receive an confirmation message and your new service will start on your old number. So these are the references which are referred to create this video. Thank you.
