MNP

Mobile Number Portability (MNP) is a service that allows you to switch over to another mobile service provider while retaining your existing mobile phone number.

Mobile number portability is implemented in different ways across the globe. The International and European standard is for a customer wishing to port his/her number to contact the new network (recipient), which then sends the number portability request (NPR) to the current network (donor). This is known as “recipient-led” porting. The UK and India are the only exceptions to implement the donor-led system. The customer wishing to port his/her number is required to contact the donor to obtain a code (Porting Authorisation Code (PAC) in the UK and Unique Porting Code (UPC) in India) which is then given to the recipient network. The recipient continues the porting process by contacting the donor with porting code. This form of porting is known as “donor-led” and has been criticised by some industry analysts as being inefficient, though prevents MNP scams. It has also been observed that it may act as a customer deterrent as well as allowing the donor an opportunity of “winning back” the customer.

South Korea introduced MNP more than 10 years ago, in 2004.

To know if your country has the MNP implemented, the easiest way to check is ask your mobile providers. MNP gives mobile carriers a good opportunity to lurk in more customers, as retaining one’s mobile number while switching to a better option of service is indeed very attractive.

Here are some of the websites you may use to know about different countries’ policies on MNP:

DLR – delivery report

Delivery Report

Delivery report (DLR) is a feature provided for MT SMS, informing the Sender of the current status of the message sent. There are various types of  DLRs, varying from the SMSC DLRs, handset reports or simple bind acks. All of those are provided to give the Sender an opportunity of following up on all the MT SMS sent and catch on any issues in the delivery.

All users of SureM service can receive delivery reports for the message they send. We provide both get/post method in passing on the delivery reports to the clients.

There are two types of delivery reports :

  • Handset acknowledgment
    This report will give the clients the exact information whether the target handset has received the messages or not.
  • System delivery report
    This report will give the clients the notification of the transmission of the messages to the SMSC

Whether you choose SMPP, HTTP or any other type of system integration, we can provide DLRs for all message sent by the clients in real time.

If you have any technical inquires, please contact us at sureminternational@gmail.com

 

Auto-Calling System (ACS)

Auto-Calling System (ACS) – a type of voice call service, automatically dialing the end user and playing the provided record of the message.

ACS service is widely used :

  1. To cover the areas, where SMS reception can not be guaranteed
  2. When the end user is in roaming
  3. For users with disabilities, preventing them to read the messages

In general, ACS is a good way to improve delivery rates if used in combination with SMS.

Below you may see the flow for ACS service at SureM

Benefits of ACS

  • A subscriber can still receive the verification code when a text message cannot be delivered.
  • A subscriber is given a choice to make to receive a voice call instead of a text message.
  • Speech can be recorded in different languages to suit the recipients that makes it much easier and more convenient for the recipients.

Korean LMS : similar to concatenated SMS?

What happens when I send a really long message through A2P line? Is it delivered in one piece to cell phone? Or is it cut into parts and delivered as multiple SMS? If so is the order correct?

Every company that needs to send long messages for whichever purpose faces these questions. And truth is – depending on a lot of factors the answer will be different.

Not all countries and networks support the so-called Concatenated SMS (C-SMS, Concats).

Concatenated SMS – a service, allowing delivery of SMS longer than the standard 160 GSM characters in one piece to the handset.

Number of SMS

GSM characters

Unicode characters

1 standard SMS

160

70

2 concatenated SMS

306

134

3 concatenated SMS

459

201

4 concatenated SMS

612

268

Basically, the process involves breaking the message first into multiple parts and then reattached together in the correct order into one message when delivered to the handset.

There is no fixed limit for concatenated SMS, depending on the device capacity it may vary. As for the destination and network – here’s the catch. CDMA networks do not support concatenation. So the messages will be delivered in parts to the handset, which is why for some countries SMS Hub providers always mention that they can not guarantee 100% delivery of the messages over 160 bytes (e.g. USA).

Another case where concatenation is not supported – South Korea. South Korea has a unique service called LMS (Long Message Service). Unlike other countries, for A2P providers Korean message length limit is different :

Message type

GSM characters

Unicode characters

1 standard SMS

90

45

1 standard LMS

91~2000

46~1000

From technical side, the process does not involve concatenation, the message is delivered in one whole piece from the Sender all the way to the handset.

The biggest difference and the benefit of LMS over C-SMS is it’s price. While A2P SMS providers charge the total price as SMS price x (Num. of parts in C-SMS ), Korean providers offer single pricing for LMS. It means, that no matter how long the message you sent is, 200 or 2000 bytes – you still pay the same price, while with C-SMS for really long promotional text you might have to pay 10 x SMS price.

SMPP?

The Short Message Peer-to-Peer (SMPP) is an open, industry standard protocol widely used in the telecommunication industry.

SMPP is desinged to provide a flexible data communication interface for the transfer of SMS messages between Short Message Service Centeres (SMSC), Routing Entities (RE), and SMS Application Systems (or External Short Messaging Entities (ESME)).

SMPP is an application protocol over TCP/IP, which allows fast and reliable delivery of SMS messages. The latest version of SMPP specification currently is 5.0 ( can be found at http://opensmpp.org/specs/smppv50.pdf ). At SureM, we support SMPP 3.4 and 5.0 so whichever protocol the customer prefers – we can easily modify the system or even customize it upon request.

Supported PDUs

  • bind_transmitter
  • bind_receiver
  • bind_tranceiver
  • unbind
  • submit_sm
  • data_sm
  • deliver_sm
  • enquire_link

Data Coding Schemes

  • 0 or 1 : ASCII
  • 3 : Latin 1
  • 8 : UCS2
  • 14: KSC5601

2-way SMS

2-way SMS service – a combination of MT and MO services, allowing the CLIENT to transmit messages and receive replies from the End User.

The service is provided through a virtual number, issued by the provider. Depending on the destination country, virtual numbers can be presented by long codes, short codes or standard phone numbers.

Example:

  1. Short code : 114, 4565,.. (usually up to 5-6 digits)
  2. Long code : 0133-xxxx-xxx (Korea) (special virtual number, does not look like a real phone number; issued by designated entity in each country)
  3. Standard phone number : 7-914-xxx-xx-xx, 82-10-xxxx-xxxx (in some countries Mobile carriers provide numbers similar to standard mobile numbers)

2-way service is widely used for various purposes:

  • Advertisement opt-out (unsubscribing)
  • Customer care lines (*with TOLL-free numbers)
  • Polls and surveys
  • Marketing campaigns
