TECHNICAL FIELD
[001] The present disclosure relates to a field of Mobile Number
Portability (MNP), and specifically to a system and a method for communication.
15 BACKGROUND
[002] The following description of related art is intended to provide
background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only
20 to enhance the understanding of the reader with respect to the present disclosure,
and not as admissions of prior art.
[003] Conventional methods and systems involve complex procedure
which consumes several days (may take 7 days to complete a Mobile Number Portability (MNP) porting process). Furthermore, the existing Short Message
25 Service Centre (SMSC) do not have the functionally to selectively route the SMS
over a Short Message Peer to Peer (SMPP) basis A-Party MSISDN.
[004] In conventional system architecture (100), as depicted in FIG. 1,
since MCH is not maintaining a mesh connection with MNP-UPC-Gateway (MNP-UPC-GW) (110), in case of link failure with any MCH instance, 1900 messages
30 destined to it through that UPCGW instance gets failed. Furthermore, the MCH
vendors associated in the system lacks the capacity to enhance the system and caters
2

the requirement. Hence, the need evolved to design a new architecture with an internal communication link between two active gateways.
[005] Further, in the conventional methods and systems, if the primary
(Primary UPCGW) goes down, the MCH may be informed, and manual activation
5 of the bind may be done by the MCH towards a disaster recovery (DR) UPCGW.
Also, manual activation of the binds may be done by DR UPCGW towards Application to Person (A2P) SMSC. If the Primary MNP Clearing House (PR MCH) goes down, the MCH may switch to Disaster recovery MNP Clearing House (DR MCH) and manually activate the binds with the PR/DR UPCGW. If MCH
10 instance 1 (S1) goes down, UPCGW instance 1 (S1) may not refrain from receiving
SMPP traffic from the SMSC. Instead, incoming traffic from SMSC may be tried to MCH instance 2 (S2) through UPCGW instance 2 (S2) (through internal communication between UPCGW S1 and UPCGW S2). If UPCGW S1 goes down, all incoming and outgoing traffic may be handled through UPCGW S2 until
15 UPCGW S1 is restored back. For this duration, MCH may confirm the handling of
incoming and outgoing traffic through the single UPCGW S2, which leads to link failure and fails to deliver the messages.
[006] There is, therefore, a need in the art to improve state of
communication by overcoming the deficiencies of the prior arts.

DETAILED DESCRIPTION
[0064] The following is a detailed description of embodiments of the
disclosure depicted in the accompanying drawings. The embodiments are in such
15 detail as to clearly communicate the disclosure. However, the amount of detail
offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
20 [0065] At present, a length of existing Mobile Number Portability (MNP)
porting process is curtailed from 7 days to 2 days. As a part of this change, a Unique Porting Code (UPC) may be generated by a MNP Clearing House (MCH) instead of a donor operator. The donor operator is defined as the operator in whose network the ported number had been before the port has taken place. Thus, the donor
25 operator is a cellular mobile service provider providing service to the subscriber
before porting. In such case, basis A-Party Mobile Station Integrated Services Digital Network (MSISDN), the donor operator needs to route an UPC request Short Message Service (SMS) to respective MCH. The existing Short Message Service Centre (SMSC) do not have the functionally to selectively route the SMS
30 over a Short Message Peer to Peer (SMPP) basis A-Party MSISDN.
11

[0066] The present disclosure may deploy a (MNP) Unique Porting Code
Gateway (UPCGW) to maintain complete MSISDN ranges and map the MSISDN
to Short Message Peer to Peer (SMPP) account basis respective region served by
given MCH. The present disclosure may provide MNP UPCGW to receive UPC
5 request SMS (to 1900) from whole SMSCs over the SMPP and lookup in its

14

[0079] FIG. 3 illustrates an exemplary architecture (300) of an active model
in an MNP-UPC-GW (202), in accordance with an embodiment of the present disclosure.
[0080] With respect to FIG. 3, the MNP-UPC-GW (202) may be deployed
5 to maintain whole MSISDN ranges and map the MSISDN to MCH vendor SMPP
account basis respective region served by a given MCH. The MNP-UPC-GW (202) may receive UPC request SMS (to 1900) from SMSCs over a SMPP and lookup in its MSISDN DB. The MNP-UPC-GW (202) may route the same SMS to the MCH again over a SMPP interface. The SMPP interface is a standard protocol in telecom
10 industry standards that is used for message exchange between a message centre
(MC) and an external short messaging entities (ESME's) or routing entities. The SMPP protocol is put to use by establishing a SMPP session which is based on transmission control protocol (TCP)/internet protocol (IP) suite between the MC and the ESMEs. The SMPP protocol is standardized and maintained by the SMPP
15 developers forum with versions v3.4 and v5.0 as widely accepted in the open
market.
[0081] Further, the SMPP account is a terminology used at MNP_UPC_GW
to associate a MCH vendor with a SMPP session. The SMPP account comprises of a System_id, System_password, System_type, Bind_type, CSM handling, Allowed
20 session count as the relevant parameters. The SMPP account detail is configured at
MNP_UPC_GW and used while onboarding the ESME (e.g., MCH vendor). Further, the SMPP session needs to be authenticated prior to exchange of messages. The authentication is ensured using a combination of the System_id and System password, Bind type and Allowed sessions count. All these parameters constitute a
25 SMPP account and MNP_UPC_GW maintains a separate account for each MCH
vendor to ensure segregation. The relevant parameters are defined below:
[0082] System ID - The system identifier (ID) is a unique ID assigned for
the ESME and may be used by the MC to authenticate the ESME requesting to bind.
[0083] System password - The system password may be used by the MC to
30 authenticate the ESME requesting to bind.
15

[0084] Bind type - An ESME may bind to the MC as either a transmitter
(called ESME transmitter), a receiver (called ESME receiver) or a transceiver (called ESME Transceiver).
[0085] System type – This parameter is used to categorize the type of ESME
5 binding to the MC.
[0086] CSM handling - This parameter depicts the mechanism that
MNP_UPC_GW will apply while dealing with concatenated (long) messages for a
particular ESME. The supported mechanisms are SAR_TLV (tag length value) and
UDH (user data header).
10 [0087] Allowed session count - This parameter denotes the maximum
number of connections that the MNP_UPC_GW will allow per MCH vendor.
[0088] In an embodiment, the MNP-UPC-GW (202) may support the
functionality as mentioned below:
1. The MNP-UPC-GW (202) may support SMPP interface in a server as well
15 as in a client mode.
2. The MNP-UPC-GW (202) may be able to maintain a database of all
MSISDN ranges allocated till date for all operators along with
corresponding MCH SMPP account mapping.
3. The MNP-UPC-GW (202) may support SMPP 3.4v with backward
20 compatibility.
4. The MNP-UPC-GW (202) may support any new version of SMPP as a part of roadmap requirement.
5. The MNP-UPC-GW (202) may have a support to receive a dump of entire MSISDN to MCH SMPP account mapping table in Comma-Separated
25 Values (CSV) format.
6. The MNP-UPC-GW (202) may have a suitable interface for operations team to add/delete/modify the given MSISDN range/SMPP account.
7. The MNP-UPC-GW (202) may support bulk modify option to make changes of SMPP account for multiple MSISDN ranges.
16

8. The MNP-UPC-GW (202) may be able to generate report/alarm for any A-Party MSISDN range mapping if missing in database table for a given UPC request.
9. The MNP-UPC-GW (202) may be able to generate all standard reports.
5 10. For a single SMPP account, the MNP-UPC-GW (202) may support multiple
sessions.

[0089] FIG. 4 illustrates an exemplary sequential diagram (400) of internal
communication channel between two active instances through replication and
clustering (RPC), in accordance with an embodiment of the present disclosure.
[0090] With respect to FIG. 4, an internal communication channel may be
5 an interface between two active instances through the RPC. This interface may be
designed internally. In an embodiment, the SMSC (401) sends a 1900 port out
message to the MNPUPCGW instance (402). The MNPUPCGW instance (402)
may unable to forward the 1900 port out message to the MCH system (404).
[0091] In an embodiment, internal communication may be enabled through
10 a replication and clustering framework. In this, a logical cluster of active instances
(402,403) may be formed with the help of client server architecture. Each instance (402) may be aware of its other instance (403) through configurations and when any of the instances (402,403) run first, one instance (402) may try to connect with the other configured instance (403). When one instance (402) is unable to connect
15 with the other configured instance (403), the instance (403) may assume the role of
server. The other instance (403) when run, may perform the same and may be able to establish a connection and becomes part of the cluster. The connection may enable all the data received by any one instance (403) to be replicated to other instance (403). However, in case of MNP-UPC-GW, replication happens only when
20 one instance (402) of MNP-UPC-GW fails to deliver the message to a MCH vendor
(404). As soon as other MNP-UPC-GW active instance (404) delivers the message to the MCH vendor (404), the response may be sent by following a complete path. The messages may be encoded before dispatching to other instance and similarly the messages may be decoded on recipient instance.
25 [0092] FIG. 5 illustrates an exemplary flow diagram (500) of the MNP-
UPC-GW operation, in accordance with an embodiment of the present disclosure.
[0093] With respect to FIG. 5, the subscriber (502) may be attached to either
4G or 5G network. MSISDN range provisioning may be done via a pre-loaded excel sheet at start up and runtime addition/deletion and similar MACD operations may
30 be done through an application CLI. The data may be stored in a cache and a DB.
18

[0094] The subscriber (502) may initiate an SMS to 1900 (short code) for
porting out by sending a UPC request SMS to 1900, at 504.
[0095] In case the subscriber (502) is attached to 4G, the SMS may be
received from IPSMGW and may be forwarded to the MNP-UPC-GW (508) by a
5 serving SMSC (506) over a SMPP.
[0096] In case the subscriber is attached to 5G, the SMS may be received
from SMSF and may be forwarded to the MNP-UPC-GW (508) by the serving
SMSC (506) on the SMPP.
[0097] On receipt of the SMS, the MNP-UPC-GW (508) may perform a DB
10 query to lookup whether the A-Party MSISDN belongs to MCH vendor.
[0098] Based on the series, the MNP-UPC-GW (508) may further route the
SMS to MCH vendor over the SMPP account.
[0099] To cancel porting, a port cancel request SMS may be initiated by the
subscriber (502) and forwarded to the MNP-UPC-GW (508) by the serving SMSC
15 (506) on the SMPP, at 512. Further, the port cancel request SMS may be sent to a
serving MCH (510) over the SMPP to cancel porting of messages.
[00100] At 514, the serving MCH (510) may send notifications
corresponding to the porting status to the subscriber (502).
[00101] FIG. 6 illustrates an exemplary flow chart (600) of port out message
20 flow, in accordance with an embodiment of the present disclosure.
[00102] With respect to FIG. 6, 1900 message may be received at the MNP-
UPC-GW from the SMSC for porting out to a recipient operator, at 602. At 604, the MNP-UPC-GW may validate the subscriber’s MSISDN range for MCH provisioning.
25 [00103] In case the MSISDN range is not provisioned, the 1900 message may
fail and the MNP-UPC-GW may send negative response back to the SMSC, at 606.
[00104] In case MSISDN range is provisioned, the MNP-UPC-GW may
perform query to fetch MCH vendor corresponding to the range, at 608.
[00105] If the MSISDN range of the subscriber belongs to a first region and
30 a second region, a MCH vendor may be selected as the MCH vendor, and another
19

MCH vendor may be selected if the range belongs to a third region and a fourth
region.
[00106] Once the message is submitted to the MCH vendor, process for UPC
generation may get initiated at their end, at 610.
5 [00107] FIG. 7 illustrates an exemplary flow chart (700) of UPC notification
flow, in accordance with an embodiment of the present disclosure.
[00108] With respect to FIG. 7, once the UPC generation is initiated at 610,
the UPC may be generated at the MCH end, and the MCH vendor may deliver the
UPC in a form of notification message towards the MNP-UPC-GW, at 702.
10 [00109] At 704, the MNP-UPC-GW may prepare the notification which is to
be delivered to the subscriber who had opted for the port-out.
[00110] At 706, the MNP-UPC-GW may deliver the notification to the
SMSC.
[00111] FIG. 8 illustrates an exemplary flow chart (800) of message
15 replication flow, in accordance with an embodiment of the present disclosure.
[00112] With respect to FIG. 8, once the MCH vendor is selected as per the
subscriber’s MSISDN range and the 1900 message is forwarded to the selected
MCH vendor at 802, the MNP-UPC-GW may check for existence of session with
selected MCH vendor, at 804.
20 [00113] If session exists, the message may be delivered to that MCH vendor
for further processing, at 806.
[00114] If session do not exist, the message may be replicated to other active
MNP-UPC-GW for delivery attempt, at 808.
[00115] At 810, the MNP-UPC-GW may check for existence of session with
25 selected MCH vendor. If the session with the selected MCH vendor exists, the
message may be delivered to the selected MCH vendor for further processing, as at
806.
[00116] If the session does not exist even on that MNP-UPC-GW instance,
then a negative response may be initiated and sent to the MCH vendor, at 812.
